Changshu smoothly to squeeze SuChang plastic extrusion die structure are introduced

In the modern industrial production of 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 smoothly reach below crowded SuChang introduce large plastic extrusion die structure.



the first, the internal plastic extrusion die structure



plastic extrusion die 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 second way, plastic extrusion die work



plastic extrusion 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 plastic extrusion die



plastic extrusion die is precision tools, complex shape, bear the expansion force of billet, the structural strength, stiffness, surface hardness, surface roughness and machining accuracy have higher requirements.
