Die connection structure

Abstract

The invention belongs to the technical field of forming molds, and particularly relates to a mold connecting structure. The mold connecting structure comprises a formwork which is tubular integrally,annular rib plates which are annularly distributed in the peripheral direction are arranged on the inner wall of the formwork at intervals in the axial direction of the formwork, axial rib plates which are distributed in an extending manner in the axial direction of the formwork are further arranged on the inner wall of the formwork, the shape of the peripheral surface of the formwork is maintained by the annular rib plates and the axial rib plates jointly, and outer plate sides of the annular rib plates and / or the axial rib plates are connected with the inner plate surface of the formwork atintervals in a welded manner. Therefore, a thermal conduction path can be effectively stopped by a gap between two plate bodies which are connected at intervals in a welded manner, heat loss of the formwork can be reduced, temperatures of various parts of the formwork are uniform, deformations of plate surfaces are also uniform, and the quality of products is improved.

Description

technical field [0001] The invention belongs to the technical field of molding dies, in particular to a die connection structure. Background technique [0002] In the prior art, the pipe body or cylindrical container with a relatively large inner diameter usually uses an extruder to extrude strip-shaped molten raw material, which is spirally wound on a preheated mold, and then the newly wound raw material is wrapped by a pressure roller. The belt is compacted with the previous circle of material belt. In this way, the material strip is continuously extruded, and the mold rotates and moves along its axial direction at the same time, so that the material strip is continuously wound as a whole, and after cooling and demoulding, an integrally formed seamless cylinder is formed. [0003] At present, the mold is usually made of metal materials, including the forming panel and the support frame inside the forming panel. Due to the good thermal conductivity of the metal material, t...

AI Technical Summary

Problems solved by technology

[0003] At present, the mold is usually made of metal materials, including the forming panel and the support frame inside the forming panel. Due to the good thermal conductivity of the metal material, the support frame distributed in the forming panel will act as a heat sink, causing the heat loss of the mold to be extremely fast. lead to high energy consumption in production

At the same time, in order to ensure the stability of the mold structure, the support frame is usually seamlessly welded with the forming panel, which makes the heat dissipation effect at the junction of the forming panel and the support frame better than other positions of the forming panel, so that the temperature of the forming panel is uneven, resulting in The uneven deformation of the formed panel seriously affects the product quality
