Problems solved by technology

For both the upper and lower body of the bottle cap, the demoulding method of the internal thread usually adopts the rotary demoulding mechanism, and the demoulding of the external thread adopts the Haval structure. Both the rotary demoulding structure and the Haval mechanism are very complicated and bulky. Operation and maintenance are cumbersome, and only a small number of cavities can be set in a mold to produce plastic parts, and the batch production quantity is small

Abstract

The invention discloses a forcible release multi-parting bottle cap injection mold, comprising a mold cavity and a pouring system, wherein a plastic part is arranged under the pouring system; a thirdcore insert is inserted into a first hole; a fourth cavity insert is disposed in a first annular groove; a first cavity insert is disposed at an outer circumferential surface of the plastic part withan external thread; a smooth outer circumferential surface of the plastic part is provided with a second cavity insert; a first core insert is disposed at a first internal thread; a second core insertis inserted into a second hole; and a third core insert is arranged on the end face, far away from the pouring system, of the plastic part. The invention has the advantages that the cavity inserts and the core inserts have a simple structure and a small volume, which is convenient for operation, and dozens or even hundreds of mold cavities can be arranged in a mold as required, thereby greatly improving production efficiency and reducing the number of required molds, and reducing production costs and mold manufacturing costs.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for a bottle cap with strong release and multiple parting. Background technique [0002] The bottle cap is a mass injection molded plastic part, and there are various structural forms for different requirements of the bottle cap. For both the upper and lower body of the bottle cap, the demoulding method of the internal thread usually adopts the rotary demoulding mechanism, and the demoulding of the external thread adopts the Haval structure. Both the rotary demoulding structure and the Haval mechanism are very complicated and bulky. Both operation and maintenance are cumbersome, and only a small number of cavities can be set in one mold to produce plastic parts, and the batch production quantity is small. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device with simple structure, convenient operation, and ma...
