Description

Technical Field

[0001] This utility model relates to the field of trimming technology, specifically to a trimming device for processing plastic parts. Background Technology

[0002] In molding processes such as injection molding and blow molding, due to limitations in mold design and manufacturing, as well as the shrinkage and flow of plastic materials during cooling and solidification, excess burrs or uneven surfaces often form on the product edges.

[0003] Burrs on plastic products need to be trimmed. During the operation of the grinding equipment, a large amount of plastic debris and impurities are generated and scattered on the worktable. This not only affects the subsequent processing due to the accumulation of waste material, making it inconvenient to operate, but also requires cleaning the entire impurity-filled worktable after processing, which is time-consuming and labor-intensive. At the same time, existing burr trimming is mostly straight-line trimming, which makes it difficult to trim corners and other areas, resulting in poor trimming effect of the product.

[0004] To address the aforementioned problems, a trimming device for processing plastic parts is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a trimming device for processing plastic parts, which solves the problems in the prior art where existing plastic trimming devices generate a large amount of plastic debris and impurities during operation, and where existing burr trimming is mostly straight-line trimming, making it difficult to trim corners and other areas, resulting in poor trimming effect of the product.
