Description

Technical Field

[0001] The utility model relates to the technical field of plastic molding machines, in particular to an automatic plastic molding machine. Background Art

[0002] Plastics are polymer compounds made from monomers through polyaddition or polycondensation reactions. They have a moderate deformation resistance, somewhere between that of fibers and rubber. They are composed of synthetic resins and additives such as fillers, plasticizers, stabilizers, lubricants, and colorants. The primary component of plastic is resin, which refers to a polymer compound that has not been mixed with various additives. The term "resin" originally derives from lipids secreted by plants and animals, such as rosin and shellac. Resin accounts for approximately 40% to 100% of the total weight of a plastic. The basic properties of a plastic are primarily determined by the properties of the resin, but additives also play a significant role.

[0003] However, when using existing plastic molding machines, manual demoulding is required for plastic products after molding. However, manual demoulding is time-consuming and labor-intensive, resulting in low demoulding efficiency, which in turn affects production efficiency and is not widely practical. Therefore, we propose an automatic plastic molding machine to solve this problem. Utility Model Content
