Changshu smoothly for many plastic products factory talk about plastic extrusion die structure

by:CSSSLD     2021-01-23
In modern industrial production of plastic extrusion mould occupies very important position. Extrusion die is under the action of external force make blank into a certain shape and size of tool parts, is widely used for blanking, forging, cold heading, extrusion, powder metallurgy parts suppression, pressure casting, as well as engineering plastics, rubber, ceramics and other products of compression or injection forming. Changshu comfortably for the diversified plastic products factory to introduce plastic extrusion mould and its main structure.



the first, the internal extrusion die structure



the mold with a specific or inner cavity shape, the outline of the application has the edge contour shape can be made according to the outline shape separation ( Blanking) , application of inner cavity shape can make blank to get the corresponding three-dimensional shape.



the workings of a second, extrusion die



mould generally includes moving mould and die ( Or punch and die) Two parts, the two can be divided into can close. When take out the parts separately and closed in billet injection mold cavity forming.



the third, the characteristics of the extrusion mould



mold is a precision tool, complex shape, bear the expansion force of billet, the structural strength, stiffness, surface hardness, surface roughness and machining accuracy have higher requirements.
