Description

Technical Field

[0001] The utility model relates to the technical field of molding dies, in particular to a rubber molding die. Background Art

[0002] Rubber refers to a highly elastic polymer material with reversible deformation. It is elastic at room temperature and can produce large deformation under very small external force. It can return to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature and a molecular weight that is often large, greater than hundreds of thousands. Rubber is divided into two types: natural rubber and synthetic rubber. Natural rubber is made by extracting gum from plants such as rubber trees and rubber grass, while synthetic rubber is obtained by polymerization of various monomers. Rubber products are widely used in industry or all aspects of life.

[0003] In plastic processing and production, various raw materials and additives need to be mixed together before processing. Existing small and medium-sized production enterprises generally mix the raw materials first, and then add the manually mixed raw materials into the processing equipment. This production method is inefficient, difficult to control the quality, and has high labor intensity. In addition, the existing spiral blades have a single stirring form and cannot stir the raw materials thoroughly and fully, so that solid particles still exist in the dissolved raw materials, which in turn affects the quality of the injection mold.
