Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a structure between two mold fixing plates disposed opposite to each other, which are movable toward each other when the mold is closed, and movable away from each other when the mold is opened. The present invention also relates to a quick exchange and fixing device for molds of an injection molding machine of the type in which the two mold halves can be aligned in the push-in guide and in which the clamping can be fixed by a mechanism in the aligned position.

The mold-quick fixing device of the above style for injection molding machine mold is “FNGKL-Enformation A767-
TV-9/81 (This brochure is from A-4311 Osley/Luc1wig Eng in Schubertberg.
θIKG (published by Maschinenfabrik).

With this mold-quick change device, both halves of the mold of the injection molding machine can be fixed to the fixed plate in a short time, and they can be removed from this fixed plate, thus reducing the installation time when changing the mold. is shortened.

However, the essential drawback of this known mold-quick change device is that the two mold halves cannot be connected to the mold via a large number of fixing bolts which protrude significantly from the two mold halves, which must be provided on the rear side of the two mold halves. They must be aligned and centered within the fixation plate and then fixed. Due to the unique design of this known mold-fastening device, the mold can only be changed by a relative movement of the two mold halves or the entire mold parallel to the adjustment device of the mold clamping plate. Therefore, these two halves not only have to be moved away from each other each time a tool is changed until the fixing bolts present on the two halves at the back are pulled out over their entire length; In order for the fixing bolts to properly hold each other when the mold fixing plates are combined, it is troublesome that the fixing bolts of the mold halves have to be accurately aligned with the accommodating parts to which the mold fixing plates belong. .

It turns out that changing the master mold using this known mold-quick fixing device is particularly cumbersome and therefore time-consuming. This is because the molds each time have to be removed from the exchange area of the injection molding machine by means of a lifting tool and brought into the area of the claws and calluses. Especially in the latter case,
In order to ensure that the mold suspended from the lifting tool is accurately connected to the fixing bolts of both mold halves, and the mold fixing plates are combined together, the notches to which these die fixing plates belong are made. The problem is that it has to be oriented against.

The object of the invention is to avoid all the above-mentioned disadvantages of known type-rapid fixation devices.

Therefore, it is an object of the present invention to not only allow easy and reliable mold exchange even if the interval between both mold fixing plates of an injection molding machine is as narrow as possible, but also to solve mold problems in the exchange area of the injection molding machine. The object of the present invention is to create a quick-change and fast-fastening device of the type described above, which also guarantees accurate removal and installation without any problems.

The above-mentioned problem is solved by configuring the above-mentioned device as follows according to the features recited in claim 1. That is, the crowd guide part formed on the mold fixing plate of the injection molding machine is oriented essentially horizontally and perpendicularly to the mold adjustment direction, and the rail is fixed to the injection molding machine by a guide mechanism. a feed movement mechanism for the injection tool movable laterally with respect to the crowd guide along the feed movement mechanism, and at least one feed movement mechanism extending in the direction of the crowd guide; The solution is achieved by carrying a transverse feed which allows the injection tool to be moved into and out of the crowd guide.

In order to optimize the tool change, according to the structure set forth in claim 2, there is provided a crowd guide section which can be controlled by a terminal switch and whose lateral feed section is formed by a mold fixing plate of an injection molding machine. The feed travel mechanism is provided with a travel drive unit that orients the feed travel mechanism.

Optimal control of the feed travel mechanism by means of a terminal switch can be achieved by designing the travel drive as an electrohydraulic drive unit. This is because this power unit can be controlled without problems in terms of running speed.

According to the structure set forth in claim 4, the guide mechanism of the feed traveling mechanism is composed of a pair of rollers that grip a fixed guide rail.

The important features of the present invention are as follows from claim 5. That is, two transverse feeders of equal or similar style are provided on the feed run mechanism next to each other and can be aligned alternately with respect to the crowding guide beside the mold fixing plate of the injection molding machine. It is to be.

In this case, according to claim 6, a first cross-feeding section for accommodating the injection tool to be drawn out and a second cross-feeding section for accommodating the injection tool to be attached are provided. .

In another embodiment of the quick exchange and quick fixing device according to the invention, each of the cross-feeding sections comprises a roller gang, and the feeding surface of the roller gang is arranged in the crowd guiding section according to claim 7. It is adjustable for the intrusion surface. Furthermore, according to the structure set forth in claim 8, each roller gang is provided with a sliding drive part that can be connected and disconnected from the injection tool. According to a particularly important feature of claim 9, each roller gang has two laterally spaced apart rows of rollers which are arranged parallel to each other, one row of rollers having no contact with the injection tool. A guide mechanism is provided which is oriented in the feed direction for the guide strip that is provided or formed thereon.

This guide mechanism can be aligned with respect to the crowding guide of the mold fixing plate, especially with respect to the immovable mold fixing plate of the injection molding machine.
It is ensured that each inserted injection tool engages directly and without problems with the crowding guide.

According to the structure set forth in claim 10, the guide mechanism is formed from jaws or rails that are respectively provided above the feed surface of the roller gang with a space therebetween, and the injection tool is provided between these jaws or rails. It has turned out to be particularly advantageous to design the guide strip in such a way that it is recessed. It has also turned out to be advantageous, according to claim 11, for the roller row with the guiding mechanism to have a construction width that is significantly shorter than the other roller row. This is because this roller bank only needs to carry only the tool part with the guide strip, regardless of the particular structural dimensions of the injection tool.
On the other hand, the tool is carried by a wide row of rollers.

In accordance with an embodiment of the invention, the carrying and/or connecting beam of the sliding drive projects from the feed surface of the roller gang through the spacing region between the two roller rows. This thus ensures that the injection tool to be removed and installed is actuated by the sliding drive above the feed plane of the transverse feed. According to an important feature as defined in claim 13 of the invention, one or each of the traversing parts rests on a support frame, which support frame is height-adjustable on the feed run mechanism. It is set in. In this way, the height difference that sometimes arises between the feed surface of the crossfeed and the injection molding machine crowding guide is balanced out. According to the structure set forth in claim 14, another fixed roller gang is provided between the feed running mechanism and the crowd guide of the injection molding machine, and according to the structure set forth in claim 15, another fixed roller gang is provided. The feed surface of this fixed roller gang is likewise height-adjustable relative to the crowd guide.

The quick exchange and fixing device according to the present invention is described in claim 1.
The structure described in item 6 is formed as follows. That is, there is at least one other roller gang arranged parallel to the roller gang next to the injection molding machine, for which the feed travel mechanism is removed together with the roller gang from the changing area of the injection molding machine. It can be aligned in the driving position. This roller gang transports, for example from a tool storage, the injection tool which is provided for the installation of the mold into the injection molding machine and the withdrawal of the mold from the injection molding machine one after the other, from a tool storage. It serves to guide the injection tool along the feeder or to move the injection tool from the feed travel mechanism to the tool storage.

The invention will be explained in more detail below with reference to embodiments illustrated in the accompanying drawings.

An injection molding machine 100 of conventional construction is shown in a purely schematic diagram in FIG. 1 and in FIGS. 21 and 5. FIG. At this time, it can be seen that this injection molding machine is equipped with a large number of ronds 103 having a circular cross section, for example four.

These rondos are the immovable mold fixing plate 10 of the mold fixing plate 102.
Serves for orientation with respect to 1 and a relatively slidable guide. Furthermore, especially from FIG.
It can be seen that a mold 104 is assembled from 06 and a mold chamber is formed between these mold halves.

The exchange of the mold 104 takes place horizontally in the injection molding machine, as can be readily seen in FIG.

The two mold halves 105 and 106 are locked together with special connecting elements (not shown) with the safety upper mold 104 closed for mold exchange. Both type fixing plates 101 and 102
After installing the mold 104 during this process, the connecting element is unraveled. That is, both mold halves 105 and 106 are selectively attached to the mold 10.
4 can be moved away from each other when the mold is opened, and moved closer to each other when the mold is closed.

The mold half 105 of the mold 104 rests on a flat adapter plate 109 according to FIG. 3, while the mold half 106 is similarly assembled onto a flat adapter plate 11oJ:2.

In particular, all adapter plates 109 and 110 have the same dimensions as one another, even if the different molds 104 have different dimensions.

Exchange of molds, i.e. mold 104 between mold fixing plates 101 and 102
The dismantling and assembly of the molding machine 100 takes place horizontally beside the injection molding machine 100, in particular in a direction oriented transversely to the opening and closing movement of the mold 104. This mold change is accomplished using a quick change and locking device, the structure and mode of operation of which will be described in detail below.

Mold 104 and therefore both mold halves 105 and 106
are inserted into the crowding guides 121 and 122 of the mold fixing plates 101 and 102 via adapter plates 109 and 110, in which the clamping in the manner of slidable cams 123 and 122' is carried out via a mechanism. Fixed.

Crowd guiding part 121 formed beside mold fixing plate 101
is formed by two strips which are arranged mirror-symmetrically to each other on their end faces, which on the one hand touch the adapter plate 10, as can be clearly seen in FIG.
Guide surface 121 oriented parallel to the crowd direction of No. 9
', but on the other hand, the end face I of the adapter plate 109
It has a support surface 121' attached to the front surface of Q9'.

The support surface for the adapter plate 109, which can be inserted into the insertion guide 121 of the mold fixing plate 101 parallel to its surface, is provided in particular by a projection 121 integrally formed on the strip 121.
It is advantageous in this case for the supporting surface 121 ′ and the cooperating end face portion 109 ′ of the adapter plate 109 to be oriented obliquely to the end face of the mold fixing plate 101 .

Crowd guide portion 21 of mold fixing plate 102 of adapter plate 109
In order to facilitate the introduction into the crowd, inclined guide surfaces 118 are formed at the entrance ends of the crowd guide section 121.
(FIG.), such that this guide surface cooperates with an associated counter surface 120 in the crowding surface of the adapter plate 109.

Guide surface 1 of crowd guide section 121 formed by strips
21' and the supporting surface 121' ensure that the adapter plate 109 and thus the entire mold 104 are centered and aligned with respect to the stationary mold fixing plate 101 exactly parallel to the crowd direction and also laterally. Ru.

The cam 123 used as a tightening mechanism to fix the adapter plate 109 to the mold fixing plate 101 has a wedge-shaped surface 124.
, and this wedge-shaped surface forms the inclined end surface portion 109' of the adapter plate 109, as seen in FIG.
contact so that the action takes place. A cam 123 with a wedge-shaped surface 124 is slidably mounted in the strip forming the crowd guide 121 and, as can be clearly seen from FIGS. It is actuated by a pressurized medium cylinder 125 seated on the outside of the piece.

After the entire mold 104 is accurately fixed to the fixed mold fixing plate 101 via the adapter plate 109 of the mold half 105, the slidable mold fixing plate 102 is moved in the direction of the adapter plate 110 of the mold half 106. be approached. In this case, adapter plate 1
10 is formed as a strip through its horizontal longitudinal edge and is connected to the mold fixing plate 1, as can be seen in FIG.
It is in operational contact with the horizontal surface 122' of the crowd guide part 122 assembled on the end surface of 02.

Before the adapter plate 110 abuts the end face of the mold fixing plate 102 with its back side, the fine protrusion 11 of this mold fixing plate
3 engages in the centering notch 115 of the mold clamping plate 102, so that a precise alignment of the mold half 106 in the mold clamping plate 102 to which it belongs is achieved.

A slidable cam 122″′ is used to finally secure the adapter plate 110 and the mold halves 1o6 to the mold fixing plate 102.
is helpful. This cam 122″′ is guided in a strip forming the crowd guide 122 and
It forms a wedge-shaped surface 124 in the same manner as the cam 123 belonging to the. The cams 123 are preferably moved individually onto the cams 122'' via a pressure medium cylinder 125, which is also provided on the outer side of the strip 122 according to FIG. A correspondingly obliquely formed wedge-shaped surface 1 of the adapter plate 110 via a wedge-shaped surface 124 of the adapter plate 110.
10', an effective clamping mechanism is thus formed for securely fixing the adapter plate 110 to the mold fixing plate 102.

Due to its structurally simple design, the quick fixing device according to FIG. 5 requires little installation space and is therefore also suitable for use in combination with molds 104 which have only a small structural height. It's easy to see if there is one.

Of particular importance is that the mold 104 to be replaced is removed and installed using a quick change device. The rapid change device is equipped with a transport transport mechanism 103, by means of which the molds 104 are moved from and/or into the original exchange area of the injection molding machine. In this case, the feed travel mechanism 103 is moved along a guide rail 152, which is fixed to the guide mechanism 131. This guide rail connects the feed traveling mechanism 103 to the crowd guide sections 121 and 12 of the mold fixing plates 101 and 102 of the injection molding machine 100.
2, the injection molding machine 100 is provided in the injection molding machine 100 so as to be guided to move in an angular position that is reliably perpendicular to the molding machine 2. The feed travel mechanism 106 in this case runs on a flat running surface and is in particular designed as an electrohydraulic power unit and thus has a travel drive that is infinitely controllable in terms of travel speed. In this case, the relative movement of the feed travel mechanism 103 with respect to the injection molding machine 100 is controlled via a terminal switch 155. This terminal switch is arranged in a suitable manner along the guide rail 152 and cooperates as an operating element with, for example, the guide Ws131 of the feed travel mechanism 103. As shown in FIG. 1, the guide mechanism 13 of the feed travel mechanism 130
1 is formed by a pair of rollers that grip the guide rail 132 from above in a pincer shape.

In FIG. 2.1, the guide mechanism 131 may be formed by three rollers, two of these rollers on one side (outer side) of the guide rail 132 and a third roller on the guide rail 132. The other side (inner side) of the rail 132
It is shown that it is installed in

The feed travel mechanism 130 has at least one lateral feed section 13
Advantageously, this transverse section is designed as a horizontal roller gang.

However, as can be seen from FIG.
' and 1351 are particularly advantageous. Advantageously, the two transverse sections 135' and 1331 are also formed by horizontal roller gangs.

From FIG. 1, a mold 104 installed in the injection molding machine 100
can be seen resting on the roller gang 136, for example by the lower longitudinal edges of its adapter plates 110 and 109. In this case, a sliding device 134 similarly provided on the feed traveling mechanism 130 and driven by the power
For example, a clamp that acts like a pincer is connected to the mold 104 via a rail 136. For this tightening, the rail 136 moves the mold 104 horizontally through the traversing section 133 to the injection molding machine 10.
This makes it possible to load the mold into the machine and transport it out of the injection molding machine.

The transport mechanism 130 comprises, according to FIG. 2.1, two equal sliding devices 134' and 1341 which are arranged parallel to each other at the same time and which belong to the same side as the transverse parts 136' and 153'. The traveling mechanism makes it possible to accommodate not only the molds 104 to be installed in the injection molding machine during one working cycle, but also the molds 104 to be transported out.

According to FIG. 2.1, the first installation of the mold 104 into the injection molding machine 100 is taking place. That is, here, the mold 104 to be disassembled from the injection molding machine 100 is not shown in order to simplify the drawing.

In order to assemble the mold 104 into the injection molding machine 100, the mold 1
A feed traveling mechanism 15 driven by a drive unit 1 that brings 04 closer
0 is correspondingly precisely controlled for the injection molding machine 100 via the terminal switch 135, as already mentioned. What is important in this case is the type 104 to be incorporated.
As shown in FIG. 2.1, the mold fixing plate 101 is accurately oriented with respect to the crowd guiding portion 121 of the mold fixing plate 101 which is fixed at least by the adapter plate 109 thereof.

In order to ensure this exact alignment of the mold 104 to be installed, the roller gang of each transverse section 133' and 133' is provided with a guide mechanism 157 oriented in the direction of feed. 4, this guide mechanism consists of two jaws or rails 158 and 139 which are spaced apart from each other above the feed surface of the roller gang, between which an adapter plate 109 is attached at its lower longitudinal edge. engage at the part.

The roller gangs of each of the two traversing sections 133' and 153' are formed by two rows of rollers 140 and 141 arranged parallel to each other with a lateral spacing.

Guide mechanisms 137 and 138. Roller row 140 with rollers 139 has in this case a significantly shorter structural width than the other roller row 141, as shown in FIG. That is, the roller row 140 is the guide mechanism 137, 1
38 and 139 to directly support the lower longitudinal edge of the adapter plate 109.

On the other hand, the structural width of the second roller bank 141 is such that in any case this roller bank covers the lower longitudinal edge of the second adapter plate 110 of the mold 104, the structural width of the second roller bank 141 is as small as possible. It is designed in such a way that it can be supported regardless of the maximum possible structural width (FIG. 4). Both roller rows 14 of each of the transverse sections 133' and 133' are formed as roller gangs.
A longitudinal gap 142 is maintained between 0 and 141 through which sliding devices 134' and 134'
The collar projects beyond the feed surface of the crossfeed section and rests there on a connecting rail 136 for the mold 104.

When the sliding device 164' is activated, the transverse feed section 133'
The mold 104, supported on a roller gang, is inserted horizontally into the injection molding machine 100. In this case, the mold 104 first reaches the roller gang 134 which is grouped in the injection molding machine 100 at the lower longitudinal edge of its adapters 109 and 110, i.e. is stationary. This roller gang is connected to the roller gang 133' of the feed traveling mechanism 130 and the fixed plate 101 of both types.
and 102, bridging the gap between the integrated area.

When the mold 104 is advanced further forward by the sliding device 134, the adapter plate 109 of this mold is attached to the fixed mold fixing plate 10.
1. In this case, orientation is also performed at the same time. Subsequently, by actuating the pressure medium cylinder 125, a clamping mechanism formed as a slidable cam 123 is actuated. This tightening mechanism presses and fixes the adapter plate 109 against the mold fixing plate 101 via its wedge-shaped surface 124 and the associated wedge-shaped surface 109'.

Subsequently, the movable mold clamping plate 102 is approached towards the mold 104, which mold clamping plate is centered within and fixed to the movable clamping plate 102 in the manner detailed above. Ru.

Before the mold 104 placed on the new cross-feed section 133' is assembled into the injection molding machine again, the injection molding machine 104 is
The feed travel mechanism 130 is moved so that the mold 104 installed therein can first be removed from the injection molding machine.
A second cross-feed section 1" is provided. Since the construction and mode of operation of both cross-feed sections 133' and 133" are the same, each of them can accommodate a mold 104 to be dismantled or assembled. I can do it.

For a reliable and permanent operating method of the rapid change device, it is important that the cross section 133 and the two cross sections 135' and 133' are always precisely aligned with the crowd plane of the crowd guide 121. It is. The traversing parts 133' and 133' therefore also rest on a frame 144, which is supported in a stepless and adjustable manner on the running mechanism 145 via an adjusting mechanism 145, for example via an adjusting spindle with a self-locking effect. ing. Unevenness of the guide path for the transport run 130 in the exchange area of the injection molding machine 100 and/or any possible foundation settling of the injection molding machine 100 can be easily eliminated in the manner described above.

Roller gang 1 fixedly provided on injection molding machine 100
43 must also be provided in such a way that it can in any case adapt exactly to the mounting and dismantling surfaces of the reservoir of the mold 104, in order to achieve an unobjectionable and permanent working mode of the quick-change device. That is, the roller gang 143 with
The feed surfaces of the injection molding machine 100 must be able to be aligned as precisely as possible with the supporting surfaces of the lower crowding guides 121 and 122 of the mold fixing plates 101 and 102 of the injection molding machine 100.

As is clear from FIGS. 5 and 6, for this purpose the roller 146 of the roller gang 143 is coupled with the sliding piece 1.
47 , the slide piece is seated in a bearing pedestal 148 and in which two adjusting spindles 14 are mounted.
It is suspended via 9.

The adjusting spindle 149 is in this case formed, for example, by a screw, which is supported with its polygonal head on a plate 150 of the bearing pedestal 148 and which is connected to the sliding piece 1.
47 into the thread 151 thereof. locking nut 15
2 ensures in each case an adjustment of the adjusting spindle 149 with respect to the sliding piece 147, which is formed in the same manner by a headed screw and which is also formed by a plate 15 of the bearing base 148.
The sliding piece 1 is moved by the presser foot spindle 153 sitting in the
47 is fixed within the bearing stand 148. Presser spindle 1
53 also cooperates with the locking nut 154 in such a way that it is possible to ensure the respective adjustment state.

In FIG. 2.2, two stationary roller gangs 155 are shown on the side of the injection molding machine 100 and spaced apart from it.
' and 155' are shown provided as feeders for mold 104. In this case, these feeding devices 155' and 155' may be driven together with the feeding devices provided opposite to each other. ' is driven to act as a feeder to derive the mold. The head ends of the two feeding devices 155' and 155' are arranged in parallel, so that the feeding traveling mechanism 1 is moved by these devices.
The transverse feeds 133' and 133' present on the feed carriage 30 are brought into the same position by a suitable movement of this feed run 130.

To make this possible, the guide rail 132 is led through the injection molding machine 100 into the area of the feed devices 155' and 155'. This is shown in Figure 2.2. Such an arrangement is suitable for at least the feeding devices 155' and 1.
It is advantageous if 55' does not have an excessive distance from the injection molding machine 100. However, both feeders 155' and 15
5' is located at a significant distance from the injection molding machine 100, the feed travel mechanism 130 is provided with a steerable travel mechanism whose travel movement is directed to the bottom via an inductive control. It is advantageous to control with laid guide rails. However, in the area of the injection molding machine 100 the feed running mechanism 130 itself is guided via a guidance control along a guide rail 132 and therefore its guiding mechanism 15
1 engages this guide rail, thus ensuring precise movement control.

By using the quick change device described above, it is possible to quickly and unobtrusively change the molds in an injection molding machine according to a programmable process, and this significantly reduces the downtime of the injection molding machine. becomes possible.
