Novel HALF block mold opening structure

Abstract

The invention provides a novel HALF block mold opening structure. The novel HALF block mold opening structure comprises two matched HALF blocks, an ejector sleeve, a threaded mold core and an inner mold core, wherein the threaded mold core and the inner mold core are arranged in the ejector sleeve; a sealing glue hole is formed in the junction between the two HALF blocks; the lower end face of each HALF block is provided with a mold opening bevel inclining to the inner wall of the sealing glue hole and extending to the inner wall of the sealing glue hole; the mold opening bevels of the inner walls of the sealing glue holes are opposite in the mold opening direction; and the two sides of the ejector sleeve are provided with mold opening slopes matched with the two mold opening bevels. The novel HALF block mold opening structure at least has the advantages that the structure is compact, the size is small, damage is unlikely to occur, the equipment processing and maintenance cost is greatly reduced, processing and control are easy, the number of mold cavities is increased, the production efficiency is greatly improved, assembling and disassembling are convenient, and the like.

Description

technical field [0001] The invention relates to a novel HALF block mold opening structure applied in the field of mold opening. Background technique [0002] The structure of the HALF block (one of the two halves that make up a whole) is a common structure in the field of molds. Usually, the mold opening of the HALF block is realized by moving up and down the oblique guide pillars obliquely inserted in the two HALF blocks. The disadvantages of the mold-opening structure of the inclined guide post are: since the HALF must have an assembly hole for the installation of the inclined guide post, the HALF block will be made quite large, and the material cost is high; the inclined guide post is suitable for mold opening within an angle of 30 degrees , it is not suitable for mold opening at an angle of more than 30 degrees. The mold opening structure of the entire HALF block is large and will occupy a large mold space; the number of cavities of the mold in the injection molding mach...

[0002] The structure of the HALF block (one of the two halves that make up a whole) is a common structure in the field of molds. Usually, the mold opening of the HALF block is realized by moving up and down the oblique guide pillars obliquely inserted in the two HALF blocks. The disadvantages of the mold-opening structure of the inclined guide post are: since the HALF must have an assembly hole for the installation of the inclined guide post, the HALF block will be made quite large, and the material cost is high; the inclined guide post is suitable for mold opening within an angle of 30 degrees , it is not suitable for mold opening at an angle of more than 30 degrees. The mold opening structure of the entire HALF block is large and will occupy a large mold space; the number of cavities of the mold in the injection molding machine of the same specification is not high, and the production efficiency is low; The size of the hole and the hanging table is difficult to control, which is not conducive to processing, and the size is difficult to ensure uniformity; the inclined guide post is easily damaged due to uneven force, and the maintenance cost is high. , the mold must be removed from the whole machine to replace it when disassembling and assembling. The maintenance time is long and the downtime is long, which affects the production progress and efficiency.
