Auxiliary supporting and sliding guiding mechanism for ejection of rear mold push plate

Abstract

The invention relates to an auxiliary supporting and sliding guiding mechanism for ejection of a rear mold push plate, which comprises a rear mold, a rear mold bottom plate and a sliding guiding assembly, the rear mold bottom plate is L-shaped and comprises a horizontal part and a vertical part, a plurality of horizontal guide columns are symmetrically arranged on the vertical part of the rear mold bottom plate, the rear mold is in sliding connection with the rear mold bottom plate through the guide columns, and the sliding guiding assembly is arranged on the rear mold bottom plate. The sliding guide assembly is used for assisting the rear mold to move along the guide column and comprises a rolling assembly and a sliding part, the rolling assembly is arranged on the horizontal part of the rear mold bottom plate, the sliding part is arranged at the bottom of the rear mold, and the rear mold slides on the rolling assembly through the sliding part; the horizontal part of the rear mold bottom plate can achieve a certain supporting effect on the rear mold, the force borne by the guide column is reduced, meanwhile, the guide sliding assembly enables the rear mold to freely and smoothly slide along the guide column, the stability of the mold ejection action is enhanced, meanwhile, the risk that the guide column is deformed and even broken due to the fact that the guide column is excessively stressed is avoided, and stable production is guaranteed.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to an auxiliary support and sliding guide mechanism for pushing out of a rear mold push plate. Background technique [0002] Mold is a variety of molds and tools used to obtain the required products by injection molding, blow molding, foundation, die-casting or forging, smelting, stamping and other methods in industrial production; mold is a tool used to make shaped products, composed of various parts, The processing of the product shape is mainly realized by changing the physical state of the formed material; after the product is formed, the mold needs to be opened and the product needs to be pushed out smoothly by the ejector mechanism to carry out the production cycle of the next product; [0003] The existing mold structure such as figure 1 As shown, a is the frame of the rear mold, b is the guide post of the rear mold, and c is the bottom plate. When the ejector mechani...

Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is to overcome the prior art. In die-casting production, when the back mold of the mold is pushed away from the back mold bottom plate, the whole back mold is suspended, and the back mold is hung on the rear mold bottom plate as a whole. On the guide post, due to the heavy weight of the rear mold, the guide post is easily deformed or even broken after being stressed
