[0018] Specifically, by setting up two cutters 14, the runner residue and the injection molded parts can be sheared and separated in one shearing process, and by moving the setting of the cylinder 7, the cylinder 7 drives the connecting plate 9 and the cutter 14 to move up and down, which can reduce the labor intensity of workers. By setting up the mold base 3 and the mold cavity 4, the shearing accuracy can be improved. By setting up the pressing assembly, the injection molded parts can be fixed, thereby avoiding shaking of the injection molded parts during the shearing process and causing shearing errors.

[0019] Furthermore, the pressing assembly is mainly composed of a slide rod 10, a spring 11 and a pressure plate 12. The slide rod 10 is slidably connected to the connecting plate 9. A pressure plate 12 is provided at the lower end of the slide rod 10. A spring 11 is provided on the outside of the slide rod 10, and the spring 11 is provided between the pressure plate 12 and the connecting plate 9. The upper end of the slide rod 10 is connected to the nut through a thread.

[0020] In this arrangement, when the connecting plate 9 drives the pressing assembly and the tool 14 to move downward, the pressing plate 12 first contacts the injection molded part, and then the connecting plate 9 drives the tool 14 to continue to move downward and squeeze the spring 11, so that the pressing plate 12 fixes the injection molded part, so that the tool 14 can shear and separate the injection molded part from the runner residue.

[0021] Furthermore, a rubber pad is provided at the bottom of the pressing plate 12, and the provision of the rubber pad can prevent the pressing plate 12 from crushing the injection molded parts.

[0022] Furthermore, the adjustment assembly is mainly composed of a handwheel 15, a screw 16, a mounting seat 19 and a guide rod 20. The mounting seat 19 is arranged between the two support blocks 2. The screw 16 is screwed in the middle of the mounting seat 19. A handwheel 15 is provided at one end of the screw 16. The other end of the screw 16 is rotatably connected to the lower knife seat 17. Guide rods 20 are provided on the front and rear sides of the screw 16. The guide rod 20 is slidably connected to the mounting seat 19, and one end of the guide rod 20 is connected to the lower knife seat 17.

[0023] Specifically, the mounting seat 19 is fixed to the base 1 by bolts, the screw rod 16 and the guide rod 20 are arranged perpendicular to the mounting seat 19, but the guide rod 20 is slidingly connected to the mounting seat 19, and the screw rod 16 is connected to the mounting seat 19 by threads.

[0024] With this arrangement, by turning the hand wheel 15, the screw 16 is rotated, thereby adjusting the distance between the lower tool holder 17 and the mold cavity 4, thereby facilitating positioning of the injection molded part by one end of the lower tool holder 17; at the same time, if the distance between the two cutters 14 needs to be adjusted, the bolts fixing the two cutters 14 can be removed, and then a pad is added between the cutter 14 and the tool mounting block 13 so that the distance between the two cutters 14 is consistent with the distance between the outermost sides of the two lower tool holders 17, and then the two cutters 14 are fixed.

[0025] Furthermore, a drop hole 18 is provided in the middle of the base 1 , through which residual material in the flow channel can be discharged, thereby facilitating collection by workers.

[0026] Furthermore, the lower knife seat 17 is mainly composed of a knife seat 21 and a connecting seat 22. A connecting seat 22 is provided at the bottom of the knife seat 21, which is connected to the adjustment component through the connecting seat 22. One end of the connecting seat 22 is rotatably connected to the screw 16, and the connecting seat 22 is guided by the guide rod 20.

[0027] During use: according to the shape of the injection molded part, replace the corresponding mold base 3, and fix the mold base 3 to the support block 2 with bolts, then turn the hand wheel 15 to rotate the screw 16, thereby adjusting the distance between the lower tool holder 17 and the mold cavity 4, so as to facilitate the positioning of the injection molded part by one end of the lower tool holder 17; at the same time, it is necessary to adjust the distance between the two tools 14, and the bolts fixing the two tools 14 can be removed, and then a pad is added between the tool 14 and the tool mounting block 13 to make the distance between the two tools 14 consistent with the distance between the outermost sides of the two lower tool holders 17, and then fix the two tools 14.

[0028] Afterwards, the worker can place the injection molded parts in the mold cavity 4 of the mold base 3, and place the runner residue between the two injection molded parts on the lower tool holder 17. Then the cylinder 7 drives the connecting plate 9, the pressing assembly and the tool 14 to move downward. First, the rubber pad on the pressing plate 12 contacts the injection molded parts. Then the connecting plate 9 drives the tool 14 to continue to move downward and squeeze the spring 11, so that the pressing plate 12 fixes the injection molded parts, so that the tool 14 can shear and separate the injection molded parts from the runner residue, and the runner residue is discharged from the blanking hole 18. Then the cylinder 7 drives the connecting plate 9, the pressing assembly and the tool 14 to move upward for reset.
