FIG. 1 is a schematic diagram of a system 100 according to an aspect of the present disclosure. The system 100 includes a mold 30 for die-casting the die-cast integrated object 10, a chuck 40 for chucking the flow path portion 11 of the die-cast integrated object 10 and taking out the die-cast integrated object 10 from the mold 30, and an overflow from the die-cast integrated object 10. A jig 20 for separating the

parts

16, 17, 18 and the die cast product part 15 is provided. The movement trajectory of the die-cast integrated object 10 chucked by the chuck 40 is indicated by a broken-line arrow in FIG.

The die-cast integrated body 10 includes a flow path part 11, one or more die cast product parts 15 coupled to the flow path part 11, and at least one

overflow part

16, 17, 18 coupled to the die cast product part 15 (see FIG. 2 and FIG. 3). The flow path part 11 of the die-cast integrated object 10 can have a sprue part 12 and a runner part 13. The die cast product part 15 is a product or a product part. Alternatively, the die-cast product part 15 is a semi-finished product or a semi-finished product part.

In some cases, the die cast product part 15 is a metal part for a slide fastener. Specifically, the die-cast product part 15 is a handle or a slider body. In some cases, a plurality of

overflow portions

16, 17, 18 are coupled to each die cast product portion 15 at different positions. In order to distinguish the

overflow parts

16, 17, 18 shown in FIG. 2, they are named as a first terminal overflow part 17, a second terminal overflow part 18, and an intermediate overflow part 16.

The die cast product part 15 is connected to the runner part 13 via the gate part 14. The intermediate overflow part 16 is connected to the die cast product part 15 via the gate part 14. The first end overflow portion 17 is connected to the die cast product portion 15 and the runner portion 13 via the gate portion 14. A second end overflow portion 18 is connected to each of the die cast product portion 15 and the runner portion 13 via the gate portion 14. The gate portion 14 is a flow passage portion that connects the runner portion 13 and the die cast product portion 15, or a flow passage portion that connects the

overflow portions

16, 17, 18 and the die cast product portion 15, or the

overflow portion

16, 17 and 18 and a flow path portion connecting the runner portion 13. In other words, the gate part 14 is not limited to the flow path part that connects the runner part 13 and the die-cast product part 15.

The mold 30 has a lower mold 31 and an upper mold 32. The lower mold 31 and the upper mold 32 may be a fixed mold or a movable mold. When the upper mold 32 is separated from the lower mold 31, the lower mold 31 is separated from the upper mold 32, or a combination thereof, the mold 30 is opened. When the upper mold 32 approaches the lower mold 31, or the lower mold 31 approaches the upper mold 32, or a combination thereof, the mold 30 is closed. Each of the lower die 31 and the upper die 32 is attached to a die attachment surface of a die casting machine (not shown). A reduction in the die casting molding cycle time (for example, the time required for cycles C1, C2, and C3 in FIG. 13) contributes to a reduction in the manufacturing cost of the die casting product section 15.

One cycle of die casting includes closing the mold 30, supplying molten metal (molten metal) into the mold 30, cooling the mold 30, and opening the mold 30. The mold 30 may have a molten metal flow path, a cavity in space communication with the flow path, and an overflow in space communication with the cavity and / or the flow path. The molten metal flow path may include a sprue and a runner. The molten metal flowing into the sprue flows into the runner and then into the cavity and / or overflow. The molten metal that flows into each cavity flows into an overflow that communicates with each cavity. The runner and the cavity communicate with each other through a gate. The runner and the overflow communicate with each other through the gate.

The molten metal supplied to the mold 30 is solidified by cooling the mold 30. The die-cast product part 15 of the die-cast integrated object 10 is a metal part that flows into the cavity of the mold 30 and solidifies. The

overflow parts

16, 17, and 18 of the die-cast integrated object 10 are metal parts that flow into the mold 30 and solidify. The flow path part 11 of the die-cast integrated object 10 is a metal part that flows into the flow path of the mold 30 and solidifies. When the flow path of the mold 30 has a sprue and a runner, the flow path part 11 of the die-cast integrated object 10 has a sprue part 12 and a runner part 13. The gate part 14 of the die-cast integrated object 10 is a metal part that flows into the gate of the mold 30 and solidifies.

The gate has a small volume compared to the runner, cavity and overflow. Separation of the die-cast product portion 15 from the die-cast integrated body 10 can be easily achieved by breaking the gate portion 14. The same applies to the separation of the

overflow portions

16, 17, and 18 from the die-cast integrated body 10. In some cases, the mold 30 includes a gate that connects the runner and the overflow, and the die-cast unit 10 includes a gate portion 14 that connects the runner portion 13 and the

overflow portions

17 and 18.

In some cases, a plurality of die-cast product parts 15 are provided symmetrically with respect to the runner part 13 of the die-cast integrated object 10. In addition, a plurality of

overflow portions

16, 17, 18 are provided symmetrically with respect to the runner portion 13. In FIG. 2, “A” is attached to one side of the runner portion 13 (upper side in FIG. 2), and “B” is attached to the other side of the runner portion 13 (lower side in FIG. 2). The A-side die cast product part 15 is symmetrical with respect to the B-side die cast product part 15 and the runner part 13. The

overflow portions

16, 17, 18 on the A side are symmetrical with respect to the

overflow portions

16, 17, 18 on the B side and the runner portion 13.

As described above, the chuck 40 chucks the flow path portion 11 of the die-cast integrated object 10 and takes out the die-cast integrated object 10 from the mold 30. The chuck 40 chucks the flow path portion 11 of the die-cast integrated object 10 by any method such as gripping, suction, and suction. The system 100 has a mechanism for moving the chuck 40. The mechanism for moving the chuck 40 may include a first linear actuator and a second linear actuator. The first linear actuator causes the chuck 40 to move in the direction in which the die-cast integrated object 10 is removed from the mold 30. The second linear actuator causes the chuck 40 to move in a direction that intersects or is orthogonal to the direction in which the die-cast integrated object 10 is removed from the mold 30. Although not necessarily limited thereto, when the first and second linear actuators are ball screws, the screw shaft of the other ball screw can be fixed to the nut of one ball screw. In another case, the chuck 40 is attached to the tip of a robot arm having links connected by joints. Based on a command from the control unit, pivoting or rotation of a certain link with respect to the base or another link is executed, resulting in a change in the posture of the robot arm and a displacement of the chuck 40.

The jig 20 for separating the

overflow parts

16, 17, 18 and the die cast product part 15 from the die-cast integrated object 10 is placed on the

overflow parts

16, 17, 18 of the die-cast integrated object 10 during the movement of the die-cast integrated object 10. At least one

first obstacle part

26, 27, 28 provided to contact and at least one provided to contact the die-cast product part 15 of the die-cast integrated object 10 while the die-cast integrated object 10 moves. There are two second obstacles 25. The terms “first” and “second” are used to distinguish an obstacle for separating the

overflow parts

16, 17, and 18 from the die-cast unit 10 and an obstacle for separating the die-cast product unit 15 from the die-cast unit 10. It is done. The first and second do not mean the first or second order.

The jig 20 may optionally include a base portion 22 to which the first and

second obstacle portions

25, 26, 27, and 28 are fixed, and a plate 21 on which the base portion 22 is disposed. The plate 21 has an opening 21 a for avoiding interference with the die-casting unit 10 that is chucked and moved by the chuck 40. In some cases, the pair of base portions 22 are arranged so as to sandwich the opening 21a of the plate 21 therebetween. One base portion 22 included in the pair of base portions 22 has first and

second obstacle portions

25, 26, 27 and 28 are provided. The other base part 22 included in the pair of base parts 22 has first and

second obstacle parts

25, 26, 26 to which the die cast product part 15 on the other side and the

overflow parts

16, 17, 18 should contact with respect to the runner part 13. 27 and 28 are provided.

1st obstacle part

26,27,28 and 2nd obstacle part 25 each include the extension part extended so that it may cross | intersect or orthogonally cross to the moving direction of the die-casting integrated object 10. FIG. Specifically, the

first obstacle portions

The extension part of the

first obstacle part

26, 27, 28 and the extension part of the second obstacle part 25 can be positioned at different positions or heights in a certain direction. For example, when a certain direction is a vertical direction, the extension part of the 2nd obstruction part 25 is positioned higher or lower than the extension part of the

1st obstruction part

26,27,28. Assuming that the die-cast integrated object 10 moves upward in the vertical direction, the extending part of the second obstacle part 25 is positioned higher than the extending parts of the

first obstacle parts

26, 27, 28. Assuming that the die-cast integrated object 10 moves downward in the vertical direction, the extending part of the second obstacle part 25 is positioned at a position lower than the extending parts of the

first obstacle parts

26, 27 and 28. In any case, the contact timing between the

first obstacle portions

26, 27, 28 and the

overflow portions

16, 17, 18 is earlier than the contact timing between the second obstacle portion 25 and the die cast product portion 15.

It is assumed that the die-cast integrated object 10 taken out from the mold 30 takes various movement trajectories. The first and second obstacles are arranged at appropriate positions according to the movement trajectory of the die-cast integrated object 10. The relative positions of the die-cast product part 15 and the

overflow parts

16, 17, 18 in the die-cast integrated body 10 are also considered. When the relative positions of the die-cast product portion 15 and the

overflow portions

16, 17, and 18 in the die-cast integrated object 10 change, the relative positions of the

first obstacle portions

26, 27, and 28 and the second obstacle portion 25 are changed. obtain.

When the first and second obstacles 25 to 28 are arranged in this order in the direction of taking out the die-cast integrated object 10 from the mold 30, the

overflow parts

16, 17, 18 are separated from the die-cast integrated object 10, and subsequently It is easy to separate the die-cast product part 15 from the die-cast integrated object 10. When the first and second obstacles 25 to 28 are arranged in this order in the direction in which the die-cast integrated object 10 is removed from the mold 30, the first and second obstacles 25 to 28 are die-cast from the mold 30. It arrange | positions in a different position or height in the direction (for example, vertical direction) orthogonal to the taking-out direction of the integrated object 10.

The removal direction of the die-cast integrated object 10 from the mold 30 is, in some cases, a direction that coincides with or extends along the horizontal direction orthogonal to the vertical direction. The first and second obstacles 25 to 28 are arranged at different positions or heights in the vertical direction.

In some cases, the plurality of

first obstacle portions

26, 27, 28 are at least a pair provided so as to sandwich a space for passage of the runner portion 13 included in the flow path portion 11 of the die-cast integrated object 10. The

first obstacles

26, 27, and 28 are included. The plurality of second obstacles 25 include at least a pair of second obstacles 25 provided so as to sandwich a space for passage of the runner part 13 of the die-cast unit 10. The plurality of

first obstacle portions

26, 27, and 28 can be arranged symmetrically with respect to a space for passing the runner portion 13 included in the flow path portion 11 of the die-cast integrated object 10. The plurality of second obstacle portions 25 may be arranged symmetrically with respect to a space for passing the runner portion 13 of the die-cast integrated object 10.

During the movement of the runner part 13, the

overflow parts

16, 17, 18 provided symmetrically with respect to the runner part 13 come into contact with the

first obstacle parts

26, 27, 28 provided so as to sandwich the movement space of the runner part 13. , Separated from the die-cast integrated object 10. The

overflow portions

16, 17, and 18 separated from the die-cast integrated object 10 can fall downward in the vertical direction according to gravity. During the movement of the runner part 13, the die-cast product part 15 provided symmetrically with respect to the runner part 13 comes into contact with the second obstacle part 25 provided so as to sandwich the movement space of the runner part 13, and is separated from the die-cast integrated object 10. To do. The die-cast product part 15 separated from the die-cast integrated object 10 can fall downward in the vertical direction according to gravity. The

overflow parts

16, 17, 18 and the die cast product part 15 are separated at different timings. Therefore, although not necessarily limited to this, the

overflow parts

16, 17, 18 and the die cast product part 15 can be managed separately by dropping them into separate boxes. The die-cast product part 15 separated from the die-cast integrated body 10 is optionally polished to remove burrs caused by the parting line of the mold.

When the

overflow parts

16, 17, 18 are provided asymmetrically with respect to the runner part 13, the

first obstacle parts

first obstacle portions

26, 27, and 28 and the

overflow portions

16, 17, and 18, and the contact timing and contact position of the second obstacle portion 25 and the die cast product portion 15. .

The

first obstacles

The L-shaped member 23 has a first flat plate 23d and a second flat plate 23e, and bends between the first flat plate 23d and the second flat plate 23e. The wide side surface of the first flat plate 23 d is placed and fixed on the side surface of the base portion 22. The end of the first flat plate 23d is brought into contact with the main surface of the plate 21. The main surface of the plate 21 is one surface of a pair of surfaces that defines the thickness of the plate 21. The second flat plate 23 e is orthogonal to the vertical direction and extends in a direction away from the base portion 22. The die cast product part 15 and the

overflow parts

16, 17, 18 are in contact with the second flat plate 23 e of the L-shaped member 23. The length of the second flat plate 23e is set so that the contact and dropping of the die cast product portion 15 and the

overflow portions

16, 17, 18 occur more reliably. By appropriately setting the length of the first flat plate 23d, the height of the second flat plate 23e along the vertical direction is appropriately set.

It is assumed that the height of the second obstacle portion 25 in the vertical direction is higher than the height of the

first obstacle portions

26, 27, and 28 in the vertical direction (see FIG. 6). It is easy to separate the

overflow parts

16, 17, 18 from the die-cast integrated object 10, and subsequently to separate the die-cast product part 15 from the die-cast integrated object 10. It is assumed that the space intervals W26, W27, W28 between the pair of

first obstacle portions

26, 27, 28 are different from the space interval W25 between the pair of second obstacle portions 25.

The number of first faulty parts can depend on the number of overflow parts. The number of second obstacles may depend on the number of die cast product parts. One first fault part is provided corresponding to one overflow part, or a plurality of first fault parts are provided. One second obstacle part is provided corresponding to one die-cast product part, or a plurality of second obstacle parts are provided. In the case of FIG. 4, six first obstruction parts are provided corresponding to a total of six overflow parts. Two second obstacles are provided corresponding to a total of two die cast product parts.

Hereinafter, based on the above description, it will be described more specifically that the

overflow parts

16, 17, 18 and the die-cast product part 15 are separated from the die-cast integrated object 10. The sprue portion 12 of the die-cast integrated object 10 is gripped by the chuck 40, removed from the mold 30, and displaced in the order of the first position P1 to the fourth position P4. The direction from the mold 30 to the first position P1 is the horizontal direction, the direction from the first position P1 to the second position P2 is the vertical direction, and the direction from the second position P2 to the third position P3 is the horizontal direction. The direction from the third position P3 to the fourth position P4 is the vertical direction.

7 to 10, all the

overflow portions

16, 17, 18 are removed from the die-cast integrated object 10 in the process in which the die-cast integrated object 10 reaches the second position P2 from the first position P1. When the die-cast integrated object 10 is in the first position P1, none of the

overflow parts

16, 17, 18 has fallen (see FIG. 7). When the die-cast integrated object 10 is moved upward in the vertical direction toward the second position P2, first, the intermediate overflow portion 16 comes into contact with the first obstacle portion 26, and the gate portion 14 breaks and falls (see FIG. 8). When the die-cast integrated body 10 is further moved upward in the vertical direction toward the second position P2, the second end overflow portion 18 contacts the first obstacle portion 28, and the gate portion 14 breaks and falls (see FIG. 9). ). When the die-cast integrated body 10 is further moved upward in the vertical direction toward the second position P2, the first end overflow portion 17 comes into contact with the first obstacle portion 27, and the gate portion 14 breaks and falls (see FIG. 10). ).

After all the

overflow parts

16, 17, 18 are removed from the die-cast unit 10, the die-cast unit 10 is moved in the horizontal direction from the second position P2 to the third position P3, and then the die-cast unit 10 is moved to the first position. It is moved vertically upward from the third position P3 to the fourth position P4. Moving the die-cast integrated object 10 from the second position P2 to the third position P3 is performed in order to dispose the die-cast product part 15 immediately below the second obstacle part 25. Moving the die-cast integrated object 10 from the third position P3 to the fourth position P4 is performed in order to remove the die-cast product portion 15 from the die-cast integrated object 10.

Although not necessarily limited to this, in some cases, moving the die-cast integrated object 10 from the second position P2 to the third position P3 means that the die-cast integrated object 10 is along the direction in which the die-cast integrated object 10 is removed from the mold 30. Is performed after the movement of the die-casting unit 10 for separating the

overflow parts

16, 17, 18 and before the movement of the die-casting unit 10 for separating the die-cast product part 15. It is assumed that the second obstacle 25 is positioned above the

first obstacles

26, 27, and 28 in the vertical direction.

When the die-cast integrated object 10 is in the third position P3 (see FIG. 11), the die-cast product part 15 is still connected to the runner part 13. When the die-cast integrated object 10 is moved upward in the vertical direction from the third position P3 to the fourth position P4, the die-cast product part 15 comes into contact with the second obstacle part 25 and falls (see FIG. 12).

The moving direction of the die-casting unit 10 for separating the

overflow parts

16, 17, and / or 18 and / or the moving direction of the die-casting unit 10 for separating the die-cast product unit 15 are determined by the die-casting unit 10 from the mold 30. It is different from the take-out direction. Using the jig 20 as a stationary or fixed member is facilitated.

The moving direction of the die-cast integrated object 10 for separating the die-cast product part 15 is parallel to the moving direction of the die-cast integrated object 10 for separating the

overflow parts

16, 17, 18. Simplification of the structure of the jig 20 is promoted.

Referring to FIG. 13, the separation of the overflow part and the die cast product part synchronized with the die casting is described. In FIG. 13, M <b> 1 indicates the state of the mold 30. H (high) indicates the mold 30 in the closed state, and L (low) indicates the mold 30 in the open state. In M2, the H level pulse indicates the fall timing of the overflow portion. In M3, the H level pulse indicates the drop timing of the die cast product part 15. In M4, the H level pulse indicates the timing at which the chuck 40 releases the sprue portion 12. The horizontal axis of FIG. 13 is a time axis.

At time t1, the chuck 40 grips the sprue portion 12 of the die-cast integrated object 10 remaining in the lower mold 31 of the fixed mold. Between time t <b> 1 and time t <b> 2, the chuck 40 moves the gripped die-cast integrated object 10 in the horizontal direction so as to leave the mold 30. As a result, the die-cast integrated object 10 reaches the first position P1. Immediately before time t2, the chuck 40 starts moving the die-cast integrated object 10 from the first position P1 to the second position P2. Between the time t2 and the time t3, the intermediate overflow part 16, the second terminal overflow part 18, and the first terminal overflow part 17 fall in contact with the

first obstacle parts

26, 27, and 28 having different heights in this order. To do. At time t3, the die-cast integrated object 10 reaches the second position. Between time t3 and time t4, the die-cast integrated object 10 moves from the second position to the third position P3. Immediately before time t4, the chuck 40 starts moving the die-cast integrated object 10 from the third position P3 to the fourth position P4. Between time t4 and time t5, the die-cast product part 15 contacts the second obstacle part 25 having a height different from that of the

first obstacle parts

26, 27, 28 and falls.

Between time t4 and time t5, after the die-cast product portion 15 is dropped, the chuck 40 moves the die-cast integrated object 10 from the fourth position P4 to the fifth position P5 (see FIG. 1), and at the fifth position P5, the sprue portion. 12 is released, and the die-cast integrated object 10 falls. The die-cast integrated product 10 to be released is obtained by removing all of the die-cast product portion 15 and the

overflow portions

16, 17, and 18. At time t <b> 6, the chuck 40 grips the sprue portion 12 of the die-cast integrated object 10 that is next die-cast by the mold 30. The description regarding the time t6 to the time t10 is the same as that described regarding the time t1 to t5, and is omitted.

As can be seen from the above description, the

overflow parts

16, 17, 18 are separated from the die-cast integrated object 10 in synchronism with the die-casting of the die-cast integrated object 10 in the mold 30, and the die-cast formed of the die-cast integrated object 10 in the mold 30. In synchronism with this, the die-cast product part 15 is separated from the die-cast integrated product 10. The chuck 40 for taking out the die-cast integrated product 10 from the mold 30 cooperates with the jig 20 to remove the overflow portion and the die-cast product portion from the die-cast integrated product 10. Even if the overflow part and the die-cast product part are removed from the die-cast integrated product 10 taken out from the mold 30, it is possible to avoid or suppress delaying the die-cast molding cycle.

When the

overflow parts

16, 17, 18 and / or the die cast product part 15 are separated from the die-casting unit 10, a die-casting process for another die-casting unit can be performed in the mold 30. FIG. 13 shows that when the mold 30 is in the closed state in the cycle C2, the overflow part falls from the die-cast integrated product 10 taken out from the mold 30 in the cycle C1, and the die-cast product unit 15 is removed from the die-cast integrated product 10 Indicates falling. Even if the overflow part and the die-cast product part are removed from the die-cast integrated product 10 taken out from the mold 30, it is possible to avoid or suppress delaying the die-cast molding cycle.

FIG. 14 describes a method for manufacturing a die-cast product part according to one aspect of the present disclosure. The manufacturing method of the die-cast product part includes the step (S1) of taking out the die-cast integrated product 10 die-cast by the mold 30 from the mold 30, and the

first obstacle parts

26, 27 having at least one

overflow part

16, 17, 18 as an overflow part. , 28 and moving the die-cast integrated product 10 so as to separate from the die-cast integrated product 10 (S2), and after separating the

overflow parts

16, 17, 18 from the die-cast integrated product 10, the die-cast product part 15 Includes a step (S3) of moving the die-cast unit 10 so as to come into contact with the at least one second obstacle 25 and separate from the die-cast unit 10.

The removal of the

overflow parts

16, 17, 18 and the die cast product part 15 from the die-cast integrated object 10 is facilitated by continuously taking out the die-cast integrated object 10 from the mold 30. It is allowed to divert the chuck 40 for taking out the die-cast integrated object 10 from the mold 30. In some cases, the movement of the die-cast integrated object 10 is caused by the movement of the chuck 40 that chucks the flow path portion 11 of the die-cast integrated object 10. The chuck 40 can chuck the sprue part 12 included in the flow path part 11, but is not necessarily limited thereto.

The manufacturing method of the die-cast product part includes a step (S4) of releasing the die-cast integrated object 10 as an option. Release of the sprue portion 12 by the chuck 40 may cause release of the die-cast integrated object 10 from the chuck 40. The die-cast integrated object 10 released from the chuck 40 is composed of only the flow path part 11, but is not necessarily limited thereto.

FIG. 15 shows a case where three pairs of die-cast product parts 15 are coupled to the common runner part 13. Even in such a case, the

overflow parts

16, 17, and 18 are separated based on the movement of the die-cast integrated object 10, and then the die-cast product part 15 is separated as described above. Therefore, the same effect as described above can be obtained. As the number of die cast product parts 15 increases, the number of

overflow parts

16, 17, 18 also increases. The jig 20 has a correspondingly increased number of first and

second obstacles

25, 26, 27, 28. The number of die-cast product parts 15 included in one die-cast integrated object 10 is arbitrary. The same applies to the number of overflow portions that increase as the number of die cast product portions 15 increases.

As shown in FIGS. 16 and 17, in some cases, the

first obstacles

26, 27, 28 and the second obstacle 25 are column parts protruding from the base part 22, respectively. The pillar portions of the

first obstacle portions

26, 27, and 28 and the pillar portions of the second obstacle portion 25 are or are extending portions that extend so as to intersect or orthogonal to the moving direction of the die-cast integrated object 10. Including. The cross-sectional shape of the pillar portion may be a circle, a polygon, or other shapes. The base portion 22 has a two-dimensionally arranged pillar portion, and a specific pillar portion is selectively used for dropping the overflow portion 16 and the die cast product portion 15 respectively. FIG. 17 shows that diagonally hatched pillars are selectively used. The amount of protrusion of the selected column portion from the base portion 22 is set such that contact with the overflow portion 16 or the die cast product portion 15 occurs. The amount of protrusion of the column portion not selected from the base portion 22 is set so that contact with the overflow portion 16 or the die-cast product portion 15 does not occur. Although not necessarily limited to this, the two-dimensional arrangement of the column portions is configured by arranging columns of column portions arranged along the vertical direction in a row direction (horizontal direction) orthogonal to the vertical direction. Although not necessarily limited to this, the outline of the two-dimensional arrangement of the pillars is rectangular. The cross-sectional area and arrangement density of the column portions are appropriately set depending on the application.

As shown in FIGS. 18 and 19, only the die-cast product part 15 and the

overflow parts

16, 17, 18 on the A side of the runner part 13 are formed, and only the part of the jig 20 corresponding to the A side may be used. is assumed.
