Tee pipe injection mold and using method thereof

Abstract

The invention provides a tee pipe injection mold and a using method thereof. The tee pipe injection mold comprises a mold frame structure, a first position core loosing and demolding mechanism for a mold core loosing and demolding part, a second core loosing and demolding mechanism for a mold core loosing and demolding part, a third core loosing and demolding mechanism for a mold core loosing and demolding part and a fourth core loosing and demolding for a mold core loosing and demolding part, wherein the first position core loosing and demolding mechanism and the second position core loosing and demolding mechanism are a dual-linkage mechanism driven by the same oil cylinder; and the third position core loosing and demolding mechanism and the fourth position core loosing and demolding mechanism are circular pipe circular sliding block type core loosing and demolding mechanisms. Through the adoption of the technical scheme of the tee pipe injection mold provided by the invention, the complexity of a core loosing mechanism of a middle bent pipe location when a conventional multi-cavity tee pipe product is designed by a multi-cavity mold is simplified, and the mold structure of the tee pipe injection mold is simplified, so that the reliability of an arc core loosing mechanism and the production efficiency of the mold injection are improved; the production and manufacturing cost of the mold is reduced; and the tee pipe injection mold is reasonable in structural design, compact in structure, stable to operate, and safe and reliable.

Description

[0001] This application is a divisional application for an invention patent application with the application number: 2015104032275, the name of the invention-creation: a three-way pipe injection mold, and the application date: July 10, 2015. technical field [0002] The invention relates to the field of injection mold mechanism design, in particular to a three-way pipe injection mold and a method for using the same. Background technique [0003] like figure 1 As shown in the figure, when the three-way pipe product is molded, the difficulty in demoulding the product lies in the core-pulling and demoulding of the 90° elbow in the middle part. It is difficult for the mechanism to achieve multiple cavities in one mold. Therefore, it is necessary to design a special core-pulling and demolding mechanism for the elbow part to complete the demoulding of the elbow part of the product with more than two cavities and the corresponding mold structure; at the same time, it is also necess...

Problems solved by technology

[0003] like figure 1 As shown, when the three-way pipe product is molded, the difficulty of demoulding the product lies in the core-pulling demoulding of the 90° elbow part in the middle part. It is difficult for the mechanism to achieve multiple holes in one mold. Therefore, it is necessary to design a special core-pulling and demoulding mechanism for the elbow part to complete the demoulding of the elbow part and the corresponding mold structure for products with more than two cavities; at the same time, it is also necessary to ensure that the core-pulling mechanism is more accurate. The simpler the mold, the easier it is to process, and the principle of relatively reducing the production cost of the mold, and the simpler the mechanism, the better its reliability and stability
