Description

Injection mold of even feeding

Technical Field

The utility model relates to the technical field of injection molds, in particular to an injection mold with uniform feeding.

Background

The die is a tool for making the blank into a workpiece with a specific shape and size under the action of external force. The method is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the molding processing of compression molding or injection molding of engineering plastics, rubber, ceramics and other products. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by using 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 and combined. And taking out the workpiece when the workpiece is separated, and injecting the blank into the die cavity for forming when the workpiece is closed. 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 machining precision, and is one of important marks of the mechanical manufacturing level.
