Product Description
eadpiece and mould: the nose consists of alloy steel inner sleeve and carbon steelcoat, inside the nose with molding mold.It is the role of head rotation movement of the plastic melt into a parallel straight line, import the die set is steady, and give necessary to plastic molding pressure.Plastic plasticizing compaction in the barrel, is approved by the flow of porous filter plate along a certain head neck into the head forming die, die core die set appropriate coordination, the formation of cross section and decreases the annular space, make the plastic melt around the conductor to form a continuous solid tubular cladding layer.In order to ensure the nose in plastic flow is reasonable, eliminate accumulated plastic corner, placed tend to have a split sleeve, to eliminate the plastics extrusion pressure fluctuations, also has a set of equalizing ring.The nose is also equipped with mold correction and adjustment device, easy adjustment and correction of mold core and mold set of concentricity.Extrusion molding machine according to the head material flow direction and the Angle of the center line of the screw, will head into bevel head Angle of 120 o and crosshead.The nose of the shell is bolted on the fuselage, the mold has a mold core inside the head, with a nut fixed in the nose into the line port, the front of the mold core cities with mold core, mold core and mold core of the center hole, used by conducto
