Plastic injection mould for plastic pipe material, plastic molding, plastic plate plastic extrusion products, such as shape and size of the tool, the changshu smooth plastic processing factory introduced plastic extrusion die structure.
1, the mouth of the plastic extrusion die mold and core rod, plastic extrusion mould opening mould for the outer surface of the plastic forming parts, core rod is used for forming the inner surface of the plastic extrusion products, plastic mold opening mold and core rod decided the cross-section shapes of plastic extrusion products;
2, filters and filter plate, plastic extrusion die is the role of filter plastic melt by spiral movement into linear motion, filtering impurities and formation pressure; Also known as porous plate, plate plays a role of supporting filter at the same time also.
3, shunt and stent shunt: diverter makes the plastic melt through it split into thin ring to smoothly into the forming area, at the same time further heating and plasticizing; Shunt stand are mainly used for supporting the shunt and core rod, as well as strengthen shear mixing effect of shunt after plastic melt, but the weld mark impact strength of plastic parts. Small nose shunt and stent can be designed as a whole;
4, the nose: the nose is equal to the die set, used to assembly and supporting the nose of the parts. The nose should be connected to the plastic extruder barrel body, joint should be sealed to prevent plastic melt leakage;
5, the temperature control system: in order to ensure that the plastic melt in the nose and the normal flow of plastic extrusion molding quality, generally on the nose with can adjust the temperature of the heating system;
6, adjusting screw: adjust the screw to adjust control molding in the mouth and the clearance between the mandrel and the degree of shaft, in order to make sure the plastic extrusion plastic pieces of uniform wall thickness. Generally regulate the number of screws for 4 & ndash; — 8;
7, finalize the design model: after leaving the forming area of plastic melt has been with the given cross-section shape, but because of its high temperature still can't resist gravity deformation need to finalize the design for cooling, in order to make the surface of the plastic extrusion products have good quality, accurate size and geometry shape.
