AI Technical Summary

Technical Problem

The drive power source of the mold slider is complicated, the lateral locking pressure is insufficient to resist the high pressure expansion force, and it is highly dependent on the direct thrust of the spring during the demolding and reset stage, which leads to easy fatigue failure. It also lacks a stable and reliable automatic reset mechanism.

Method used

The hydraulic cylinder drives the inclined extrusion block and the push block to cooperate. The vertical power is converted into horizontal mold closing force by using the mechanical wedge principle. Automatic disengagement and reset are achieved through the linkage of the reset component and the spring. Combined with the cleaning mechanism, it moves synchronously with the power source to remove impurities.

Benefits of technology

It achieves high-strength, stable locking and automatic reset without the need for additional horizontal drive equipment, reducing equipment manufacturing costs and operation and maintenance difficulties, and ensuring efficient mold operation and product quality.

Abstract

This utility model relates to the field of mold manufacturing machinery technology, and discloses a reset and locking structure for a mold slider. It includes a base and a hydraulic cylinder fixed to the top of the base. The output end of the hydraulic cylinder is fixedly connected to a telescopic column and a pressing block. The bottom end of the pressing block is equipped with a fixing mechanism. The pressing block moves downward with the hydraulic cylinder, and its side surface abuts against the side surface of a pushing block slidably connected to the base. The vertical pressure is converted into horizontal thrust through the inclined surface cooperation, achieving a dead-angle lock. A reset component is provided at the front end of the pushing block, with an inclined block slidably connected inside. When the hydraulic cylinder rises, the inclined block engages with the fixing strip, pulling the pushing block back to its original position. When it returns to the safe position, the spring inside the rotating plate releases potential energy, pushing the inclined block out to complete the unhooking. This utility model achieves high-strength locking and precise reset without additional horizontal drive, and the bottom cleaning mechanism simultaneously cleans dust, significantly reducing manufacturing costs and improving stability.
