Description

Technical Field

[0001] This utility model relates to the field of injection molding product processing, and in particular to an automated processing equipment for injection molding products. Background Technology

[0002] After the injection-molded product is completed and the product with the sprue is removed from the injection molding machine, it needs to undergo operations such as sprue removal, sanding, and applying a protective film to the outer surface. Currently, after the product is injected and cooled, the sprue is usually removed manually using a blade. The product with the sprue removed is then sanded manually using sandpaper. After sanding, the product is then coated manually before flowing into subsequent processes.

[0003] However, the existing manual processes of cutting sprues, grinding, and applying film are distributed across different workstations and require manual transfer. This not only results in high labor costs but also low work efficiency. Furthermore, fatigue from prolonged work can lead to inadequate work and affect product yield. Therefore, this has greatly troubled the injection molding industry. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an automated processing equipment for injection molded products that achieves fully automated operation, thereby greatly improving production efficiency.

A first carrier and a second carrier are slidably arranged on the worktable, with the first carrier and the second carrier spaced apart. A sprue milling assembly, a transfer assembly, a grinding assembly, and a feeding assembly are sequentially arranged on the worktable. The feeding assembly is located at the connection between the worktable and the production line. A film-applying assembly is mounted on the production line. The first carrier carries the product from its initial position and moves it towards the sprue milling assembly and the transfer assembly. The sprue milling assembly cuts off the sprue of the product. The transfer assembly picks up the product from the first carrier and places it on the second carrier. The second carrier carries the product from the transfer assembly and moves it towards the grinding assembly and the feeding assembly. The grinding assembly grinds the outer surface of the product. The feeding assembly picks up the product from the second carrier and places it on the production line. The film-applying assembly applies a protective film to the outer surface of the product fed into the production line from the feeding assembly.
