Demolding equipment for cylindrical mandrels

Abstract

The invention discloses a demolding device of a cylindrical core mold and belongs to the demolding field of core molds. The demolding device of the cylindrical core mold comprises a base, an upper rack and a lower rack, wherein the upper rack and the lower rack are fixedly connected with each other through bolts; travel guide rails and sliding blocks which are matched with the travel guide rails are mounted on the upper rack; the side walls of two ends of a demolding travel block with through holes formed in the middle and two sides of the lower bottom surface are fixedly connected with the sliding blocks through the bolts; a hydraulic cylinder is mounted in a center of a part between stand columns on the same side of the lower rack; the top of an output shaft in the hydraulic cylinder stretches into the demolding travel block through the through holes in two sides of the lower bottom surface of the demolding travel block; a mold fixing module is clamped and matched with the demolding travel block. Detachable and replaceable mold fixing blocks and lining plate structures can met the demolding usage requirement of cylindrical core molds such as a cylinder core mold and a prismatic core mold with length being less than 1,500nm and diameter being less than 300nm, so that the effect that a machine serves several purposes can be achieved; the structure of a previous mechanical demolding machine is simplified; the demolding operation is facilitated; the overall size of the demolding machine is reduced.

Description

technical field [0001] The invention belongs to the field of core mold demoulding, and in particular relates to a demoulding device for a cylindrical core mold. Background technique [0002] At present, with the development of industry, parts in many fields of products must be manufactured by mold forming, which involves the demoulding problem of the core mold after the mold is manufactured, and the demoulding machine appears. In the Chinese patent "a pipe demoulding machine with a diameter of 300-4000mm", publication number: CN102179929, a pipe demoulding machine for demoulding a mold and a mandrel is disclosed, which can release a large winding pipe from the mould. However, the pipe demoulding machine has a complex structure; and because the demoulding machine is a horizontal demoulding machine, that is, the mold is parallel to the ground, the centering requirements of the demoulding machine of this structure are relatively high, and the clamping of the mold is very inconv...
