A deformation compensation device used on the frame of injection molding machine or die-casting machine

Abstract

The invention discloses a deformation compensation device for a rack of an injection molding machine or a die-casting machine. The deformation compensation device comprises a pair of guide blocks and an expansion device, wherein the two guide blocks are embedded in a side plate below the rack and are arranged at an interval along the stressed direction of the side plate; the expansion device is arranged between the two guide blocks and is used for driving the guide blocks to move towards the reverse direction of the stressed direction of the side plate under the action of a driving device. By the adoption of the deformation compensation device, the deformation of a rack track under the action of material ejection pressure is eliminated to the greatest extent, the qualified rate of injection molding or die-casting products is improved, and the production efficiency is further improved.

Description

technical field [0001] The invention relates to the technical field of injection molding or die-casting, in particular to a deformation compensation device used on the frame of an injection molding machine or a die-casting machine. Background technique [0002] When using injection molding or die-casting technology to produce products, it is first necessary to close the movable mold and the fixed mold to form a product cavity, then inject molten raw materials into the cavity, and shape the product under a certain pressure. During the process of injection of raw materials or pressure molding, due to the action of pressure, the movable mold and the fixed mold will have a certain deformation, which directly leads to the change of the original shape of the cavity, and finally leads to the change of the shape of the injection molding or die-casting product, even It is to produce unqualified products, which seriously affects production efficiency and increases production costs.

AI Technical Summary

Problems solved by technology

This deformation intensifies the relative deformation between the movable and fixed molds, which seriously affects the shape of the injection molded product.

However, the impact of the deformation of the frame itself on the product is often ignored by technicians. Therefore, for some products with high injection pressure and high product quality requirements, it is obviously not enough to design the deformation compensation device on the movable mold or the fixed mold.
