Description

Injection mold with quick ejecting structure

Technical Field

The utility model relates to the technical field of injection molds, in particular to an injection mold with a quick ejection structure.

Background

The die is a tool for forming a blank into a product with a 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.
