[0002] As a type of part that is easy to mold, has good strength, and has a variety of functions, injection molded parts are increasingly used in industry, and the amount used is also increasing. However, after the injection molded parts are formed, a gate will be left on the workpiece, and the gate needs to be removed to obtain the finished injection molded part. Because injection molded parts are usually diverse and the gate positions are different, the gates on injection molded parts are usually cut manually. This process is time-consuming and labor-intensive, and the production speed is low. Especially when the gate on the injection molded part is thick, it is more time-consuming and labor-intensive to cut, and it is even easy to damage or scratch the injection molded part during the process of cutting the gate, resulting in the product becoming a defective product. In addition, the quality of manual shearing is usually difficult to unify, which is easy to affect product quality. Utility Model Content

When a workpiece 10 with a different structure needs to be pressed, only the conformal pressing block 9 on the pressing manipulator 3 needs to be replaced.

[0030] The support seat 2 is detachably connected to a conformable support membrane 12 adapted to the bottom structure of the workpiece 10. The support seat 2 supports the workpiece 10 through the conformable support membrane 12 so as to better support the workpiece 10 and prevent it from being crushed or scratched during the process of cutting the gate. When it is necessary to support a workpiece 10 of a different structure, it is only necessary to replace the conformable support membrane 12 on the support seat 2.

[0031] The height adjustment assembly 8 includes an upper mounting plate fixedly connected to the movable end of the linear drive mechanism 7 and a lower mounting plate fixedly connected to the shearing mechanism 6. Both the upper mounting plate and the lower mounting plate are provided with vertical adjustment grooves that can be used in conjunction with each other. The upper mounting plate and the lower mounting plate are positioned and fixed by locking bolts passing through the adjustment grooves to adjust the height of the shearing mechanism 6 as needed to adapt to the precise shearing of the gates of different workpieces 10.

[0032] In this embodiment, two sets of shear gate tooling are symmetrically arranged on a frame, so that one pick-and-place robot can be used to place and take out parts from two support seats, saving equipment costs and improving production efficiency.

[0033] The shear gate tooling includes two supporting seats 2 and two pressing manipulators 3 that cooperate with each other, and are used to fix the workpiece 10 from both sides so that the workpiece is fixed more stably, thereby achieving a better shearing effect.

[0034] The pressing robot 3 includes a lifting cylinder 13 fixed on a support seat with its movable end facing upward and a rotating motor 14 arranged on the movable end of the lifting cylinder. The conformable pressing block 9 is detachably arranged on a connecting block fixedly connected to the movable end of the rotating motor 14.

[0039] Working process: After the workpiece 10 is injection molded, it is taken out from the injection mold by the pick-and-place robot and placed on the supporting fetal membrane 12 on the support seat 2. Then, the workpiece 10 is pressed by the pressing robot 3 through the conformal pressure block 9, the end of the gate 11 is clamped by the clamp 4, and then the gate 11 is sheared by the shearing mechanism 5. After the shearing is completed, the finished workpiece is removed by the pick-and-place robot and sent to the next process.

[0040] Among them, before the workpiece 10 is placed on the support seat 2, the shearing mechanism 6 is driven by the linear drive mechanism 7 to move away from the support seat 2, and the pressing robot 3 is also driven away from the support seat 2 to make room for the workpiece 10 to be put down. After the workpiece 10 is placed in place, the pressing robot 3 presses the workpiece 10, and then the shearing mechanism 6 is driven by the linear drive mechanism 7 to move to the shearing position for shearing.

[0041] The gate cutting tool of the utility model has an ingenious structure. Through the mutual cooperation of the support seat, the pressing manipulator, the clamp and the shearing device, the workpiece is in a state similar to being fixed by humans and the gate is pulled before the gate is sheared. The gate is sheared off in a stable state with the gate end fixed. This makes the shearing mechanism more effective during shearing, so that the shearing can be very smooth and accurate, and the automation of gate shearing is realized. The shearing effect is good, especially when the gate is rough. Compared with the original manual shearing method of gate, the shearing time is greatly shortened, the shearing quality is improved, the practicability is strong, and it is worthy of promotion.
