Description

Technical Field

[0001] This invention relates to injection molding technology, specifically to a semi-automatic in-mold implantation device for injection molding inserts. Background Technology

[0002] In injection molding insert molding processes, it is often necessary to simultaneously insert various inserts with different structures, such as copper busbars, bushings, and nuts, into the mold cavity before injection molding. Current production methods mostly rely on manual loading and unloading of parts, which leads to problems such as misinstallation, omission, and reversed insertion of inserts, resulting in a high scrap rate of injection molded products. Manual insertion of inserts has poor positioning accuracy, easily causing insert misalignment and interference with the mold, affecting the dimensional accuracy and assembly performance of the product. At the same time, manual loading and unloading is inefficient and labor-intensive, and cannot achieve integrated operation of insert gripping, insertion, and finished product removal, resulting in long production cycles and difficulty in meeting the needs of stable mass production.

[0003] In addition, existing insert insertion equipment is mostly a single insert adapter structure, which cannot be compatible with the simultaneous clamping, positioning and ejection of multiple types of inserts such as copper busbars, bushings and nuts, resulting in poor versatility; and it lacks an automatic detection step after insert loading, so the problem of incorrect or missing inserts cannot be eliminated in advance, further reducing the production yield.

[0004] Therefore, developing a semi-automatic in-mold implantation device that can achieve precise positioning, automatic detection, integrated gripping and implantation, and finished product unloading of various types of inserts has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

If an insert is found to be faulty, it is removed; otherwise, it is sent to the transfer station. A robot drives a fixture to the transfer station, where the copper busbar clamping and ejection mechanisms, bushing clamping and ejection mechanisms, and nut clamping and ejection mechanisms simultaneously grasp the corresponding inserts. The robot moves the fixture into the mold of the molding device, where each ejection mechanism precisely ejects the insert into the mold cavity. The fixture then releases the insert and exits. After mold closing and injection molding, the robot drives a finished product clamping mechanism to grasp the molded product, moves it to the unloading station for release, and the product is conveyed to the full inspection station via a conveyor belt, completing one work cycle.
