Sectional type detachable neck ring mold of hollow blow molding machine

Abstract

The invention discloses a sectional type detachable neck ring mold of a hollow blow molding machine, and relates to the technical field of blow molding machines. The sectional type detachable neck ring mold comprises a neck ring mold body, the neck ring mold body comprises an inner mold core and an outer neck ring mold, the inner mold core comprises an inner upper mold core body and an inner lowermold core body, an inner lower groove is formed in the top of the inner lower mold core body, an annular groove corresponding to the inner lower groove is formed in the top of the inner upper mold core body, and the outer neck ring mold comprises an outer upper neck ring mold body and an outer lower neck ring mold body. According to the sectional type detachable neck ring mold of the hollow blowmolding machine, the neck ring mold body is divided into the inner mold core and the outer neck ring mold, the inner mold core is divided into the inner upper mold core body and the inner lower mold core body, and the outer neck ring mold is divided into the outer upper neck ring mold body and the outer lower neck ring mold body, so that when the neck ring mold body is replaced, only the two partsof the inner lower mold core body and the outer lower neck ring mold body need to be replaced, the size is small, the weight is light, assistance of carrying tools and other people is not needed, only the replaced inner lower mold core body and the replaced outer lower neck ring mold body need to be heated, time and heating energy are saved, the occupied space is small, and maintenance resourcesare saved.

Description

technical field [0001] The invention relates to the technical field of blow molding machines, in particular to a segmented detachable die of a hollow blow molding machine. Background technique [0002] Blow molding machine is a kind of plastic processing machine. After the liquid plastic is sprayed out, the plastic body is blown and attached to a mold cavity of a certain shape by using the wind blown out of the machine to make a product. Blow molding is also called hollow blow molding. A rapidly developing plastic processing method, the tubular plastic parison obtained by extrusion or injection molding of thermoplastic resin is placed in the split mold while it is hot, and compressed air is injected into the parison immediately after the mold is closed to make the plastic parison Inflate and cling to the inner wall of the mold, and after cooling and demoulding, various hollow products can be obtained. The manufacturing process of blown film is very similar to the blow moldin...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a segmented detachable mouth die of a hollow blow molding machine, which solves the problem that the die of a common hollow blow molding machine is large in size and heavy in weight, and the replacement process requires the use of handling tools and multiple people. Assisted to complete, and the traditional die assembly is difficult to locate, the replacement takes a long time, after the replacement is completed, the heating ring needs to be reheated, and the heating time is long, resulting in low utilization rate of the equipment shift, which greatly affects the production efficiency. Moreover, the power consumption is high, and the traditional die will also take up a lot of space and spend a lot of resources on maintenance and maintenance.
