The automatic removal mold structure of the scrap according to the present invention will be described with reference to the accompanying drawings.

First, in the present specification, the workpiece is a concept including an interlayer paper, an insulating paper, a double-sided tape, various films, and the like, which can be cut into a desired shape by a press.

As shown in Figures 1 to 3, the automatic removal mold structure of the scrap according to the present invention is

Discharge part 13 having a cut part 11, a support block 13b arranged on one side of the cut part 11, and a pushing pin 13c connected to the support block 13b to push out the scrap S. An upper base 10 comprising a; A guide plate 20 arranged at a corresponding position of the discharge part 13 and having a guide hole 21 for discharging the scrap S; And a support part 31 arranged at a corresponding position of the cutout part 11 of the upper base 10, and a collecting part 33 arranged under the guide plate 20 to collect scraps S. It comprises a lower base (30).

As shown in Figures 1 to 3 in the mold structure that is easy to discharge the scrap (S) according to the present invention, the upper base 10 is

It comprises a cutting portion 11, and the discharge portion 13 arranged on one side of the cutting portion (11).

First, the elevating means 1 for raising and lowering the upper base 10 is provided at the upper portion of the upper base 10 according to the present invention.

The elevating means (1) is provided with a press (not shown) using a working fluid, such as pneumatic or hydraulic.

And one side of the upper base 10, attached to the right side in Figure 1 is provided with a cutting portion 11,

The cutting part 11 is made of a cutting plate (11a) coupled to the lower right portion of the upper base 10 and a plurality of cutters (11b) connected to the lower surface of the cutting plate (11a),

The cutter 11b is formed with a plurality of notches 11c (or split blades) in the blade portion.

Therefore, when the upper base 10 is lowered by the elevating means (1) to press the workpiece (SH)

The remaining attachment portion SE is formed in the scrap S to be cut and separated from the workpiece SH by a gap between the notches 11c of the cutter 11b, so that the scrap S is the workpiece SH. It will remain completely unplugged from the.

Next, the upper base 10 according to the present invention is provided with a discharge part 13 on the left side of the cutting part 11,

The remaining attachment portion SE of the scrap S attached to the workpiece SH is completely separated by the support block 13b and the pushing pin 13c and discharged to the collection portion 33 of the lower base 30. To collect the scrap (S).

However, the discharge part 13 according to the present invention introduces a pushing pin 13c as a configuration for easily and simply separating the scrap S from the workpiece SH.

This is to solve the following problems that occur when the scrap (S) is pushed only by the pinching unit in order to separate and discharge the scrap (S) attached to the workpiece (SH).

In other words, a predetermined gap is formed in each notch 11c portion of the cutter 11b.

In this case, the frequent use of the cutter 11b may cause the distance between the gaps of the blades of each notch 11c to be widened or narrowed. In this case, the residual of the scrap S adhered to the workpiece SH may be caused. The amount of attachment of the attachment portion SE may vary.

In this state, by pushing the scrap S by the support block 13b of the discharge part 13, the amount of attachment of the remaining attachment part SE is increased when the remaining attachment part SE is separated from the workpiece SH. Many parts are attached as they are without being separated from the work (SH)

Even though the support block 13b is completely lowered, the remaining attachment portion SE is held in the state in which the scrap S is suspended from the workpiece SH by the remaining attachment portion SE which is not separated from the workpiece SH. Only the portion of the scrap (S) separated from the (SH) is moved in the downward direction and the problem that the scrap (S) is attached to the workpiece (SH) as it may occur,

In addition, such a phenomenon may occur continuously during subsequent work, and thus the failure rate may be increased.

In addition, the work efficiency is reduced due to the inconvenience that the worker has to remove the scrap S, which is not separated from the work SH, by hand, and the unnecessary expense such as labor costs,

In severe cases, the problem is that the product cannot be used and the economic losses that must be disposed of cannot be prevented.

In the present invention to solve the conventional problems as described above

Pushing pins (13c) connected to each of the support blocks (13b) is projected in the downward direction to press the scrap (S) attached to the workpiece (SH) in the vertical direction,

In this case, the lower portion of each of the pushing pins 13c has a pointed wedge shape, so that the scrap S is pushed downward in the state where the scrap S is taken, so that the scrap S together with each pushing pin 13c. Come down,

At this time, the remaining attachment portion SE of the scrap S which is not separated from the workpiece SH also has to fall completely from the workpiece SH.

Therefore, the introduction of the pushing pin according to the present invention allows the scrap to be completely separated and removed from the steel product, thereby lowering the defective rate of the product, and also reducing the work efficiency and economic loss due to unnecessary work. Will have

 On the other hand, the upper base 10 according to the present invention is composed of a cut portion 11 and the discharge portion 13,

The cutting work of the work SH and the discharge work of the cut scrap S can be simultaneously performed by one stroke of the press, so a separate post work is required to separate the scrap S from the work SH. To reduce labor costs for this,

In addition, it can improve productivity and economic efficiency by improving work efficiency through automated process.
