Description

Double-slider outer secondary core-pulling structure for mold

Technical Field

The utility model relates to the technical field of mold, specifically be an outer secondary structure of loosing core of double slide block for mould.

Background

Moulds (Mule) are used for obtaining various moulds and tools of required products by injection moulding, blow moulding, extrusion, die casting or forging forming, smelting, stamping and other methods in industrial production. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The processing of the appearance of an article is realized mainly through the change of the physical state of a formed material. It is a tool for making blank into product with specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.
