Description

A plastic mold with its own anti-scratch coating

Technical field

The utility model relates to the technical field of plastic molds, in particular to a plastic mold with its own anti-scratch coating.

Background technique

Plastic mold is the abbreviation of a combined mold used for compression molding, extrusion, injection, blow molding and low foaming molding. The coordinated changes of the convex mold, concave mold and auxiliary molding system can process different shapes and sizes. A series of plastic parts, various tools and products we use in daily production and life, ranging from the base of machine tools and fuselage shells to as small as a blank head screw, button and the shell of various household appliances, all related to Molds are closely related.

By referring to the authorized patent number "CN214056117U", "a plastic mold with its own anti-scratch coating", it can be seen that this patent uses a cylinder to push down the upper mold, so that the upper mold contacts the lower mold for the molding operation. After the molding of the plastic part is completed, the cylinder lifts the upper mold, and then starts the adjusting motor. The adjusting motor drives the driving bevel gear to rotate through the rotating shaft. The meshing effect of the driving bevel gear and the driven bevel gear is used to drive the two rotating screws to rotate synchronously. The threaded connection between the rotating screw and the drive block causes the drive block to drive the lower end of the ejector rod to move, so that the upper end of the ejector rod pushes the discharge plate upwards, thereby quickly pushing the plastic parts to the upper end of the lower mold. It can achieve rapid demoulding, which greatly facilitates demoulding operations, improves work efficiency, and solves the technical shortcomings of existing plastic molds that are inconvenient for rapid demoulding.

The utility model provides another solution to solve the above problems.

The information disclosed in this Background section is merely intended to increase understanding of the general background of the present invention and should not be construed as an admission or in any way implying that the information constitutes prior art that is already known to those of ordinary skill in the art.
