Mold for facilitating demolding of rubber part

Abstract

The invention relates to a mold for a rubber part, in particular to a mold for facilitating demolding of the rubber part, and belongs to the technical field of mold equipment. The mold comprises an upper mold, an upper mold core, a lower mold, a first lower mold core and a second lower mold core; the upper mold and the lower mold are vertically correspondingly arranged; an upper mold cavity is formed in one end, facing the lower mold, of the upper mold; the upper mold core is arranged in the upper mold cavity; a lower mold cavity is formed in one end, facing the upper mold, of the lower mold; the first lower mold core and the second lower mold core are arranged in the lower mold cavity; the lower half of the second lower mold core is sleeved with the first lower mold core; the lower end of the second lower mold core is connected with a piston rod of a demolding oil cylinder; and the upper mold core and the second lower mold core are connected through multiple opening and closing devices. The mold is simple, compact and reasonable in structure, time-saving and labor-saving, demolding of the rubber part comprising a reverse buckle structure can be accurately and efficiently completed, pull-damage to the structure of the rubber part is avoided, and the demolding working efficiency is improved.

Description

technical field [0001] The invention relates to a mold for rubber parts, in particular to an easy-release mold for rubber parts, which belongs to the technical field of mold equipment. Background technique [0002] As an engineering material, rubber is widely used in the entire industrial production, such as rolling stock, ships, automobiles, instruments, aviation and bridges, etc. For most rubber parts, it is used as a vibration damping element, called rubber spring Or rubber spring pads, etc., there are also many rubber parts used for seals. In recent decades, in order to slow down the vibration and noise generated in the operation of vehicles, ships, aircraft, etc., rubber parts have received more and more attention and application in my country's engineering, and a number of large-scale professional manufacturers of rubber parts have been developed. . [0003] In the prior art, when the rubber part with an undercut structure is demolded, the demoulding is generally carr...

AI Technical Summary

Problems solved by technology

When the size of the undercut structure of the rubber part is small, manual demoulding can still be carried out normally, but when the size of the undercut structure of the rubber part is large, it is not only time-consuming and labor-intensive, but also easy to pull Injury to rubber parts, resulting in product damage
