Changshu smoothly da plastic products factory is introduced plastic extrusion die structure design requirements

Plastic extrusion die is a kind of molding, plastic extrusion mold discharging way is just real phenomena through out this action. It is widely used for blanking, forging, cold heading, extrusion, powder metallurgy parts of repression, pressure casting products such as compression or injection forming. This is inseparable with its special design, the following smoothly da plastic products factory in changshu introduced plastic extrusion die structure design requirements.



1, plastic extrusion die with a particular profile or inner cavity shape, application of plastic injection mould cavity shape can make the blank to get the corresponding three-dimensional shape.



2, plastic extrusion die structure complicated shape, able to withstand the expansion force of the billet, and plastic injection mould for structure strength, stiffness, surface hardness, surface roughness and machining accuracy have higher requirements.



3, 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 plastic extrusion forming mold cavity.



4, plastic extrusion die mainly adopts alloy structural steel, under high temperature and high load can still maintain good dimensional stability, ensure the service life of mould and prolong the service life of the plastic injection mould.
