1, an injection mold 100 is mounted on a trunk of a vehicle. At least one metal mold 200 is mounted on an outer surface of the injection mold 100, and an engaging pin 210 formed on the outer periphery of the metal mold 200 The operator inserts the coupling pin 210 into the injection molded product 100 and then the coupling pin 210 is first bent and temporarily fixed. Thereafter, the coupling pin 210 is further inserted into the injection molded body 100 using the pressing portion 6 according to an embodiment of the present invention. Firmly squeeze it.

The main body 2 is installed on the ground, the workbench 20 is formed in the middle, a top board 3 is formed on the top of the workbench 20, and a space is formed inside.

A hydraulic motor 21 is provided in the lower part of the main body 2 to supply the hydraulic pressure to the driving part 4. A switch 23 for controlling the lowering and elevating of the pressing part 6 manually is formed at one side.

A plurality of coupling grooves 202 having a predetermined length are formed on the upper surface of the work table 20 and the bolts 204 are inserted into the coupling grooves 202.

Therefore, the coupling groove 202 can be inserted into the head of the bolt 204, and has a hat-shaped cross section so that the threaded portion can be inserted.

The worktable 20 can be firmly supported by fastening the bolts 204 to the coupling grooves 202 on both sides of the worktable 20. The workbench 20 can be selected and replaced according to the size of the injection-molded product 100.

The driving unit 4 is mounted on the upper part of the main body 2 and provides the power required for pressing operation of the pressing unit 6. [

The driving unit 4 includes a hydraulic cylinder main body 42 mounted on the upper portion of the main body 2 and an upper plate 3 of the main body 2 for moving up and down in conjunction with the movement of the piston engaged in the hydraulic cylinder main body 42 And a piston rod 44 vertically penetratingly connected to the piston rod 44. A press portion 6 is mounted on an end portion of the piston rod 44. [

Two hydraulic cylinder main bodies 42 are mounted on the upper part of the main body 2, and the number of the hydraulic cylinder main bodies 42 may be increased or decreased as necessary.

The piston rod 44 penetrates through the upper plate 3 of the main body 2 and is coupled to the work table 20 so as to be drawn in.

One piston rod 44 is mounted on one hydraulic cylinder main body 42 and the compression bonding portion 6 is coupled to the piston rod 44. In order to smoothly secure the lifting and driving of the compression bonding portion 6, The guide rods 46 are coupled to the left and right sides of the piston rod 44 so as to connect between the upper plate 3 and the pressed portion 6 of the piston rod 2.

The press portion 6 is connected to the driving portion 4 and is installed in the space of the main body 2, and presses the injection-molded product 100 while moving up and down.

The pressing portion 6 includes a plate 62 mounted on the end of the piston rod 44 and having a plurality of engaging grooves 622 formed on the lower surface thereof; A module plate 64 formed with an engagement hole 643 detachably coupled to the engagement groove 622 of the plate 62 and having a plurality of fasteners 69 protruded from the upper portion thereof; And a press punch 66 vertically arranged to be coupled to each of the plurality of fasteners 69.

The plate 62 is connected to the piston rod 44 at the center thereof and the guide rods 46 are mounted on both sides of the piston rod 44 to be connected to the upper plate 3 of the main body 2.

One plate 62 is connected to one piston rod 44 connected to one hydraulic cylinder body 42 and a module plate 64 is mounted on the plate 62. As shown in FIG.

Therefore, the number of the module plates 64 connected to the two hydraulic cylinder bodies 42 is two.

The module plate 64 is in close contact with the lower portion of the plate 62 and the plate 62 is opened in the lower surface to form a coupling groove 202. The coupling groove 202 is formed in the plate 62, T 'shape. The hooking hole 643 is a hexagonal head bolt and the head of the hexagonal head bolt is inserted into the upper portion of the coupling groove 202. A nut is fastened to the lower portion of the bolt to support the nut to the module plate 64, 64 and the plate 62 can be integrally fixed.

The nut 64 is coupled to the coupling groove 622 of the plate 62 and the coupling groove 641 of the module plate 64 and then the nut is fastened so that the module plate 64 is fixed to the lower portion of the plate 62 And can be mounted in a close contact state.

Therefore, the module plate 64 can be replaced, and the reason why the module plate 64 is replaceable is that it needs to be replaced when the conditions such as the size change or breakage of the pressurizing punch 66 are reached.

The pressing punch 66 is formed in a tapered shape so as to have a smaller area as it goes downward, and a rectangular flat portion 663 is formed at a lower end thereof.

The pressing punch 66 is arranged corresponding to the engaging pin 210 of the metal mold 200 and the lower end of the pressing punch 66 strongly presses the engaging pin 210.

Hereinafter, the operation of the present invention will be described.

The injection mold 100 is first placed on the work table 20 and the metal mold 200 is mounted so that the engagement pin 210 passes through the injection mold 100. After the operator inserts the engagement pin 210 using a tool, Is first folded and fixed.

When the control unit is operated by operating the control unit in a state where the injection molded product 100 is fixed, the pressing unit 66 is lowered by the driving of the driving unit 4, So that the injection molding 100 is pressurized to a certain extent to form a strong stiction operation.

In this way, the coupling pin 210 of the metal mold 200 can be integrated by bending and pressing the injection mold 100 with a strong force.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, It is obvious that the claims fall within the scope of the claims.
