Precision forming mold for engineering composite material transmission pieces

Abstract

The invention discloses a precision forming mold for engineering composite material transmission pieces. The mold comprises an upper mold, a middle mold, a lower mold, a mold body, a mold core, a tray, a heating device and the like, wherein the mold body and the middle mold, the mold core and the lower mold, and the tray and the mold body are positioned in a taper fit mode; a sprue gate communicated with a cavity is formed on the upper mold; the upper mold, the mold body, the mold core and the tray form the cavity; and an intelligent control electric heating device around the mold body is arranged in the middle mold. By the mold, the uniformity of a temperature field of a mold pressing effective vulcanization system can be ensured, the whole physicochemical properties, dimensional accuracy, material compactness and surface quality of the product are improved, mold pressing vulcanization time is shortened, and high efficiency, energy conservation and environment friendliness are achieved; in addition, a workpiece can be respectively separated from the mold core and the mold body through a demolding hole formed on the lower mold, the automation degree is improved, the operating strength of workers is reduced, and the mold can be widely applied to precision forming manufacturing equipment of high-performance engineering composite material transmission pieces such as various bearings, sealing bodies, shock absorbers, elastic couplings and the like.

Description

technical field [0001] The invention relates to a mold, in particular to a mold for precise forming of transmission parts made of engineering composite materials. Background technique [0002] With the continuous development of science and technology, based on the requirements of resource conservation and environmental friendliness, engineering composite materials are gradually replacing traditional metal materials in the manufacture of key components in mechanical transmission systems, bearings, seals, couplings in high-efficiency transmission systems It is more and more widely used in the manufacture of important basic components such as shock absorbers and shock absorbers. Such as water-lubricated rubber alloy bearings made of engineering composite materials, high-performance seals, high-elastic couplings and other new engineering composite transmission parts are widely used in machinery, ships, aviation, aerospace, petroleum, chemical, water conservancy and other fields....

AI Technical Summary

Problems solved by technology

[0003] The traditional production process of engineering composite transmission parts mainly uses upper and lower heating plates for molding heating and manual demoulding. The traditional production process has the following problems: 1) The temperature of each part of the vulcanized engineering composite transmission parts is uneven and difficult to control, resulting in The dimensional accuracy of the product is poor, and the quality is difficult to guarantee; 2) The hot press vulcanization time is long, the effective heat utilization rate is low, and the production efficiency is low; 3) The degree of automation is low and the operation intensity is high
