Special-shaped pipe extrusion molding mold and using method thereof

Abstract

The invention discloses a special-shaped pipe extrusion molding mold and a using method thereof, and relates to the technical field of molds. Through cooperative use of an auxiliary stripping assembly, clamping force between a first clamping plate and an upper movable clamping plate, clamping force between a second clamping plate and a lower fixed clamping plate, position determination of a second positioning plate, and driving of a transverse distance between a first positioning plate and the second positioning plate under the action of a third hydraulic cylinder, the position of an inner mold core is determined at the moment, the precision is guaranteed, the material taking space is increased through overturning of an upper fixing plate, and the problems that the structure of a special-shaped pipe is relatively complex, after the special-shaped pipe is produced, the complex structure easily causes demolding difficulty of a product, the produced product is difficult to demold and take out from a mold, and the fixed mold core structure fixes the part taking space, product taking is not flexible, and the production process is affected are solved.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a mold for extrusion molding of heterosexual pipes and a method for using the same. Background technique [0002] Mold (mújù), various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material. Known as the "Mother of Industry". [0003] Under the action of external force, the blank becomes a tool with a specific shape and size. Widely used in blanking, die forging, cold heading, extrusion, powder metallurgy parts pressing, pressure casting, and compression molding or inje...

AI Technical Summary

Problems solved by technology

[0004] The traditional molds for heterosexual tubes have certain defects in use. Due to the structural characteristics of heterosexual tubes, the structure of heterosexual tubes is relatively complicated, so that after the production of the heterosexual tubes, the complex structure is easy to cause difficulty in demoulding the product , it is not easy to remove the produced product from the mold, and the fixed core structure even fixes the space for picking, and the product picking is not flexible, which affects the production process
