Description

Technical Field

[0001] The utility model relates to the technical field of plastic product production, in particular to a pressing device for plastic product production. Background Art

[0002] Plastic products refer to various products that are made by processing and molding plastic as the main raw material. Plastic products are widely used in daily life and industrial production. They have the advantages of light weight, corrosion resistance, flexible molding process and low price.

[0003] After searching, a clamping device for plastic product production with the publication number CN218226254U includes a base and a fixing mechanism, a support column is installed on one side of the top outer wall of the base, and a fixing plate is hinged on the top outer wall of the support column, and a circular groove is provided on the top outer wall of the fixing plate, and a circular block is rotatably connected to the inner wall of the circular groove through a bearing, and the fixing mechanism is located above the circular block, and sliding grooves are provided on both sides of the top outer wall of the circular block, and the fixing mechanism includes a connecting plate that slides on the inner wall of the sliding groove. When the scheme needs to fix the two sides of the plastic product, the connecting plate is fixed to the circular block through a buffer spring and a pressing block, and then the threaded rod is rotated to drive the fixed circular block to move to fix the plastic product, which increases the fixing method of the plastic product and facilitates the subsequent processing of the outer wall of the plastic product. However, the above technical scheme still has the following shortcomings when it is actually used:

[0004] This solution fixes the two sides of the plastic product by rotating the two threaded rods to move the two fixed round blocks toward each other. For cylindrical plastic products, the force exerted by the fixed round blocks on the side walls of the plastic product is concentrated on two points. When the applied force is small or the fixed round blocks are asymmetric, the forces on both sides of the plastic product are uneven, and the plastic product is prone to slipping during processing, affecting the processing efficiency and manufacturing accuracy. When the applied force is large, this concentrated force may cause excessive local force on the plastic product, which may easily cause uneven stress distribution, resulting in deformation or rupture of the plastic product, thereby affecting the processing quality and the service life of the plastic product.

[0005] Therefore, it is necessary to design a clamping device for plastic product production to solve the above problems. Utility Model Content
