No-thimble-plate core pulling molding mold

Abstract

The invention provides a no-thimble-plate core pulling molding mold, and relates to the technical field of mold equipment. The no-thimble-plate core pulling molding mold comprises an upper mold base,a molding fixed block, a molding module, a core pulling module, a fixed plate, a lower mold base, a thimble module, two inclined guide columns, two side pulling modules and two cushion block modules;the molding fixed block is used for achieving a positioning effect on the molding module before parting; the molding module and the core pulling module are used for molding products; a molding part isdriven by a limiting part to perform an internal shrinkage motion near the axis of an internal shrinkage guide block to realize demolding of molded products; thimbles are contacted with the top endsof the inner surfaces of molded workpieces; and during opening of molds, support springs are continuously located in a rebound state to realize support fixation of the molded workpieces by the thimbles after internal shrinkage of the core pulling module. The no-thimble-plate core pulling molding mold is simple in structure, saves a thimble plate, and can effectively realize stable support of the molded workpieces.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to a core-pulling forming mold without a thimble plate. Background technique [0002] Mold, 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 shape an article. 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. [0003] After the mold is opened, a layer of thimble plate is generally provided in the traditional mold and several thimbles are arranged on the thimble plate to eject the product after the mold is opened. , because its caliber is very small, it is very difficult to use the thimble plate to eject it through the thi...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a core-pulling molding die without a ejector plate, which has a simple structure, eliminates the ejector plate and can effectively realize stable support for the molded workpiece for taking out. It is very difficult to eject the long cap-shaped product after it is formed, and the number of ejector pins required is not much, which leads to the technical problem of high manufacturing cost
