Description

Molding parts of plastic molding machines

Technical Field

The utility model relates to the technical field of plastic molding, and more specifically to a molding component of a plastic molding machine.

Background technique

Plastic molding processing equipment is developed on the basis of rubber machinery and metal die-casting machines. It heats the plastic film and then blows or blister-forms it.

At present, in the process of using plastic molding machines, molding molds are needed to mold plastic products. However, it is not easy to quickly position the molding molds during use, which makes the molds easy to collide when closing the molds, shortening the service life. In addition, the plastic molded parts after opening the molds need to be manually removed by the user, which is time-consuming and reduces production efficiency and convenience of use.

For example, the molding parts of the plastic molding machine disclosed in announcement number CN219256441U include an assembly frame, an upper template and a lower template. The outer surface of the assembly frame is respectively installed with a motor frame and a mounting block, the outer surface of the mounting block is fixed with a positioning rod, the outer surface of the positioning rod is respectively sleeved with an upper pressure plate and a lower pressure plate, and the outer surfaces of the upper pressure plate and the lower pressure plate are fixed with a plug-in frame and a hinge block.

It can be seen from the above-mentioned public scheme that although the upper and lower templates are plugged into and positioned with the plug-in racks set on the upper and lower pressure plates, the mold mounting efficiency is improved, but the positioning firmness is insufficient and it is easy to cause displacement due to vibration, which in turn causes damage to the mold when the mold is closed, shortening the service life. In addition, the molded plastic parts are not easy to remove from the mold cavity, reducing production efficiency and convenience of use.
