Description

Technical Field

[0001] The utility model relates to the technical field of injection molded part burr processing, in particular to an injection molded part burr automatic shearing device. Background Art

[0002] Injection molding is a manufacturing method for industrial product production, usually using rubber injection molding and plastic injection molding. It is to inject thermoplastic plastics into molds to make plastic products of various shapes. When the plastic product is in the state of a blank, there are some burrs on its surface. The reason is that there is a gap between the two molds. Some plastic fluid will also fill the gap when filling the mold cavity, resulting in burrs on the plastic product blank.

[0003] When removing burrs from existing game injection molded parts, workers usually manually scrape off the burrs on the surface of the injection molded parts with a tool, which not only has low work efficiency but also easily scratches the injection molded parts. To solve the above problems, this application proposes a device for removing burrs from game injection molded parts.

[0004] The Chinese utility model patent with the current announcement number: CN218053594U discloses a deburring device for game injection molded parts, which drives the adjusting screw to rotate by turning the hand wheel. The adjusting screw can push the upper clamping seat down under the action of the surface thread, and the game injection molded parts can be clamped and fixed by the upper clamping seat and the lower clamping seat. The lower clamping seat can be driven by the No. 1 driving motor. The center of the top surface of the upper clamping seat is connected to the adjusting screw through a rotating seat. Therefore, when the lower clamping seat is driven, the upper clamping seat and the game injection molded parts can rotate synchronously. The grinding roller is driven by the No. 2 driving motor. The burrs of the game injection molded parts can be driven by the grinding roller during the rotation process. The burr removal efficiency is faster and it is not easy to cause the injection molded parts to be shoddy.

[0006] Therefore, an automatic burr trimming device for injection molded parts is proposed. Utility Model Content
