Description

Technical Field

[0001] The utility model relates to the technical field of plastic mould processing, in particular to a plastic mould lifting mechanism. Background Art

[0002] Plastic molds are tools used in the plastic processing industry to match plastic molding machines and give plastic products a complete configuration and precise size. Due to the wide variety of plastics and processing methods, the structures of plastic molding machines and plastic products vary in complexity, and the types and structures of plastic molds are also diverse.

[0003] A plastic mold ejection mechanism is proposed in the Chinese utility model patent with application number 201721154499.7, including: a cylinder, a bracket, a guide shaft, an upper mold, a sleeve, a lower mold, an ejector pin, a base, a stopper, an injection hole, a push rod, and a groove; a base is provided at the bottom end of the bracket, and a cylinder is provided at the top end of the bracket; a lower mold is provided at the middle part of the top end of the base, and the upper mold is provided on the guide shaft through a sleeve; a groove is provided at the middle part of the bottom of the lower mold, and a push rod is provided in the groove between the two guide shafts; a stopper is provided on the upper part of the guide shaft, and the piston rod of the cylinder is connected to the upper mold; ejectors are provided on both sides of the top end of the push rod. The device has the advantage that the plastic product can be easily taken out of the plastic mold after cooling and solidification.
