Description

Technical Field

[0001] The utility model relates to the field of plastic product processing equipment, in particular to a pressing device for producing plastic products. Background Art

[0002] Plastic products are a general term for daily necessities, industrial products, etc. that are made of plastic as the main raw material, including products made from all processes such as injection molding and blister molding. Plastic is a type of synthetic polymer material with plasticity. Plastic products need to be polished to increase their aesthetics. Plastic products usually need to be polished by a polishing device after production. When plastic products complete the initial processing, some edges will have defects such as burrs and need to be polished.

[0003] The existing patent authorization announcement number is: CN218984403U, and the patent name is: A clamping device for plastic product production, which moves the upper clamping plate downward by extending the telescopic end of the third electric cylinder, and clamps and fixes the plastic product body on the top of the lower support plate through the upper clamping plate, thereby achieving clamping and fixing of the plastic product body;

[0004] When polishing the plastic ring-shaped product to be processed, not only the outside of the plastic ring-shaped product to be processed needs to be polished, but also the side wall of its inner cavity needs to be polished. The existing clamping device can only polish the outer side wall of the plastic ring-shaped product to be processed after pressing the plastic ring-shaped product to be processed. When the side wall of the inner cavity needs to be polished, other equipment needs to be replaced. The operation process is cumbersome and inconvenient to use. For this reason, we propose a clamping device for plastic product production. Utility Model Content
