AI Technical Summary

Technical Problem

Existing injection molds are easily shaken by equipment operation when opening and closing the mold, resulting in unstable mold clamping, affecting the mold forming quality of plastic products, and prone to flashing.

Method used

An injection mold is designed including a frame, a mold mechanism, a hydraulic cylinder, a preheating assembly and a gate assembly, through the extension and contraction of the hydraulic cylinder, the support of the guide column, the heating of the preheating assembly and the gate assembly. Thermal conduction ensures stable mold clamping of the dynamic and fixed molds, reduces external forces and vibration effects, and realizes limiting and self-locking of the dynamic and fixed molds through the clamping assembly.

Benefits of technology

It effectively reduces the shaking of the moving mold during the opening and closing process, improves the stability of the mold, ensures the molding quality of the plastic products, and avoids the occurrence of flashing.

Abstract

The present invention discloses an injection mold that is easy to close the mold for plastic processing. The present invention relates to the technical field of injection molding equipment, including a frame, a mold mechanism, and the mold mechanism includes a base and a hydraulic cylinder. The top of the base is fixedly connected to a fixed mold, the output end of the hydraulic cylinder is fixedly installed with a movable mold, a clamping assembly is respectively installed on the top of the fixed mold and the top of the movable mold, a support guide column is fixedly installed in the middle of the outer side of the base, a preheating assembly is installed at the bottom of the movable mold and the bottom of the fixed mold, a gate assembly is installed in the middle of the outer side of the fixed mold, the preheating assembly is used to heat the movable mold and the fixed mold, a fan and an air supply pipe are respectively installed at both ends of the air channel, the bend of the outer side of the air supply pipe is fixedly connected to the side of the outer side of the movable mold, the air inlet end of the fan is connected to a connecting pipe, and the top of the connecting pipe is connected to a sleeve. The injection mold that is easy to close the mold for plastic processing achieves the effect of easy closing the mold, reduces the influence of external force and vibration, is not prone to shaking, and makes opening and closing the mold convenient.
