The frame 1 is slidably connected to an upper mold base 6 in the vertical direction, and the upper mold base 6 can abut and fix the position of the injection molded parts and the injection nozzle after moving downward, and the upper mold base 6 is provided with a penetration hole 7 for the injection nozzle to penetrate and limit the movement of the injection nozzle. The frame 1 is provided with a translation cylinder 8 for driving the slide 2 to move horizontally, and a lifting cylinder 9 for driving the upper mold base 6 to move downward. Two sets of cutting mechanisms for automatically cutting the injection molded parts and the injection nozzles are arranged between the slide 2, the lower mold base 3 and the upper mold base 6.

[0034] The parts after injection molding are two injection molded parts connected to the injection nozzles at the same time and are symmetrically arranged. When disassembly is required, the slide 2 is first moved away from the upper mold base 6 by the translation cylinder 8, and the injection molded workpiece can be placed in the corresponding position of the lower mold base 3 by a robot or manually, that is, the injection molded part is located in the positioning chamber 4, and the injection nozzle is located in the accommodating groove 5, and then the slide 2 is driven by the translation cylinder 8 to move to the bottom of the upper mold base 6, and the upper mold base 6 is driven downward by the lifting cylinder 9, and the upper mold base 6 is abutted against and fixed to the injection nozzle and the injection molded part, and then the injection nozzle and the injection molded part are cut by two sets of cutting mechanisms. After the cutting is completed, the translation cylinder 8 drives the slide 2 to move away from the upper mold base 6 again, and then the injection molded parts and the injection nozzle are taken away by a robot or manually, so as to achieve the effect of quickly disassembling the injection molded parts, realize mechanized operation, and reduce labor intensity.

[0035] In this embodiment, the lower die base 3 is slidably connected to the slide 2 in the vertical direction. The slide 2 is fixed with a plurality of vertically arranged guide posts 10, and the guide posts 10 are inserted through the lower die base 3. The upper end surface of the guide posts 10 is arranged in a conical shape. The upper die base 6 is provided with guide holes 11 for the guide posts 10 to penetrate, and the lower die base 3 is guided to be lifted and lowered by the guide posts 10. In addition, the cutting mechanism includes a spring 12 arranged between the slide 2 and the lower die base 3 and pushing the lower die base 3 to move upward, a cutting knife 13 arranged on the slide 2 and used to cut the injection molded parts and the injection nozzle, and a cutting opening 14 opened on the lower die base 3 for the cutting knife 13 to extend out. The cutting opening 14 is located between the receiving groove 5 and the positioning chamber 4. In this embodiment, the cutting opening 14 and the cutting knife 13 are arranged in two groups and correspond to the corresponding positioning chamber 4 and the receiving groove 5 respectively. The spring 12 is arranged vertically, and a guide rod for the spring 12 to be sleeved can be arranged between the lower die seat 3 and the slide 2. The cutting knife 13 is arranged with the blade facing upward, and the lower end surface of the upper die seat 6 is provided with an avoidance groove 15 for accommodating the protruding part of the cutting knife 13. When the lower die seat 3 moves to the right below the upper die seat 6 and splits the injection molded parts, the upper die seat 6 is driven downward by the lifting cylinder 9, and the upper die seat 6 abuts against the injection molded parts and the lower die seat 3, and pushes the lower die seat 3 to continue to move downward, so that the cutting knife 13 moves upward relative to the lower die seat 3, and the cutting knife 13 extends between the accommodating groove 5 and the positioning chamber 4 to cut the injection molded parts and the injection nozzle; in addition, the avoidance groove 15 prevents the cutting knife 13 from touching the upper die seat 6; the guide column 10 simultaneously guides the lower die seat 3 and the upper die seat 6.

[0036] The lower end surface of the lower die seat 3 is provided with a guide block 16 for guiding the cutting knife 13. The guide block 16 is provided with a guide groove 17. The side wall of the guide groove 17 is flush with the cutting opening 14, and the side wall of the cutting knife 13 is attached to the side wall of the guide groove 17. That is, when the lower die seat 3 is not pressed, the cutting knife 13 is located below the lower die seat 3 and attached to the side wall of the guide groove 17. The cutting knife accurately locates the position of the blade of the cutting knife 13, improves the cutting accuracy, and the guiding effect of the cutting knife 13 is achieved through the guide block 16, so that correct punching is achieved.

[0037] The frame 1 is provided with a positioning assembly for limiting the horizontal sliding position of the slide 2, and positioning assemblies are provided on both sides of the sliding direction of the slide 2. The positioning assembly includes a positioning frame 18 fixed to the frame 1, an adjusting screw 19 threadedly connected to the positioning frame 18, and an abutment block 20 provided at the end of the adjusting screw 19 and capable of abutting against the side wall of the slide 2. The adjusting screw 19 is horizontally arranged and parallel to the sliding direction of the slide 2. When in use, the slide 2 abuts against the corresponding abutment block 20 to limit the moving position of the slide 2, thereby playing a positioning role, ensuring that the lower die base 3 can accurately move to the bottom of the upper die base 6, thereby improving the moving accuracy.

[0038] A space is provided between the lower die base 3 and the slide 2 for the manipulator to take and place the injection molded parts. The positioning chamber 4 penetrates the side wall of the lower die base 3 and allows the injection molded parts to extend to the outer side of the lower die base 3. The slide 2 is provided with positioning blocks 21 that fit the sides of the injection molded parts. The positioning blocks 21 are provided on both sides of the injection molded parts to play a certain positioning and guiding role, and the injection molded parts are correctly taken and placed.
