Abstract
A high-speed extrusion mould for CPVC (chlorinated polyvinyl chloride) pipes comprises a flange and a head connector, the flange is mounted on a head of an extruder, a die is mounted in an opening of the head connector, a die pressing plate is mounted outside the die and is fixed with the head connector by screws, a mandrel is mounted in the die, and an extrusion cavity is formed between the mandrel and the die. The high-speed extrusion mould is characterized in that a diverting plate is mounted in the head connector, a diverting hole is manufactured in the diverting plate, a diverting cone is connected inside the diverting plate and is connected with the mandrel by a screw bolt, a diverting cavity is formed between the diverting cone and the head connector, the diverting cavity, the diverting hole and the extrusion cavity are communicated with each other, and the extrusion cavity is flared-shaped and is gradually narrowed. Since the flared-shaped extrusion cavity is gradually narrowed, high-pressure extrusion is formed, extrusion speed of the pipes is high and production efficiency is improved.
Description
Technical field
The utility model relates to the CPVC pipe mold that a kind of high speed is extruded, and belongs to the mould of plastics field.
Background technology
The CPVC material is a kind of novel engineering plastics, is characterized in corrosion such as hear resistance, acid and alkali resistance, salt, therefore, is mainly used in tubing such as producing hot-water line, chemical industry carrier pipe and electric power pipe.Producing CPVC tubing needs CPVC tubing extrusion die, and the CPVC tubing extrusion die of prior art mainly is that its shortcoming is that extruded velocity is slow with reference to traditional P VC tubing extrusion die, and production efficiency is low.
Summary of the invention
The purpose of the utility model is in order to overcome the shortcoming of prior art, to provide a kind of extruded velocity fast, the high speed CPVC tubing extrusion die that production efficiency is high.
The technical scheme of the utility model high speed CPVC tubing extrusion die is: comprise the ring flange and the head connector that are installed on the cross-head, installing port mould in the oral area of head connector, the outer installing port moulded board of mouthful mould; The mouth moulded board fixes through screw and head connector, and plug is installed in mouthful mould, and die cavity is extruded in formation between plug and mouthful mould; It is characterized in that in the described head connector flow distribution plate being installed; Be shaped on tap hole in the flow distribution plate, connect in the flow distribution plate and divide flow cone, divide flow cone to connect plug through double-screw bolt; Divide and form the shunting chamber between flow cone and the head connector; Shunting chamber, tap hole and extrude die cavity and interconnect, the described die cavity of extruding is bell mouth shape, and cavity is by dwindling greatly gradually.
The utility model discloses a kind of high speed CPVC tubing extrusion die, in the head connector, flow distribution plate is installed, be shaped on tap hole in the flow distribution plate, connect in the flow distribution plate and divide flow cone; Divide flow cone to connect plug through double-screw bolt, divide to form the shunting chamber between flow cone and the head connector, the described die cavity of extruding is bell mouth shape, and cavity is by dwindling greatly gradually; When extruding, because the cavity of shunting chamber and tap hole is bigger, the cavity of extruding die cavity is by dwindling greatly gradually; Be bell mouth shape, material flows into the shunting chamber from cross-head, flows into tap hole and extrudes the die cavity from the shunting chamber again; The formation high pressure is extruded, and makes the tubing extruded velocity fast, and production efficiency improves.
The high speed CPVC tubing extrusion die of the utility model, described flow distribution plate connect through flat key and divide flow cone, and be easy to connect, reliable by flat key.In the described head connector puller bolt is installed, puller bolt contacts with a mouthful mould, and it is firm that mouthful mould is installed, and is not loosening.
Description of drawings
Fig. 1 is the utility model high speed CPVC tubing extrusion die structural representation.
The specific embodiment
The utility model relates to a kind of high speed CPVC tubing extrusion die, and is as shown in Figure 1, comprises the ring flange 1 and head connector 2 that are installed on the cross-head; Installing port mould 9 in the oral area of head connector 2, mouthful mould 9 outer installing port moulded boards 7, mouthful moulded board 7 fixes through screw 11 and head connector 2; In the mouth mould 9 plugs 8 are installed, are formed between plug 8 and mouthful mould 9 and extrude die cavity 12, it is characterized in that installation flow distribution plate 4 in the described head connector 2; Be shaped on tap hole 13 in the flow distribution plate, connect in the flow distribution plate 4 and divide flow cone 3, divide flow cone 3 to connect plug 8 through double-screw bolt 6; Divide and form shunting chamber 14 between flow cone 3 and the head connector 2; Shunting chamber 14, tap hole 13 and extrude die cavity 12 and interconnect, the described die cavity 12 of extruding is bell mouth shape, and cavity is by dwindling greatly gradually.This programme is installed flow distribution plate 4 in head connector 2, be shaped on tap hole 13 in the flow distribution plate 4, connects in the flow distribution plate 4 to divide flow cone 3, divides flow cone 3 to connect plug 8 through double-screw bolt 6; Divide to form shunting chamber 14 between flow cone 3 and the head connector 2, the described die cavity 12 of extruding is bell mouth shape, and cavity is by dwindling greatly gradually; When extruding, because the cavity of shunting chamber 14 and tap hole 13 is bigger, the cavity of extruding die cavity 12 is by dwindling greatly gradually; Be bell mouth shape, material flows into the shunting chamber 14 from cross-head, flows into tap hole 13 and extrusion die 12 chambeies from shunting chamber 14 again; The formation high pressure is extruded, and makes the tubing extruded velocity fast, and production efficiency improves.Described flow distribution plate 4 connects through flat key 10 and divides flow cone 3, and is easy to connect, reliable by flat key.Puller bolt 5 is installed in the described head connector 2, and puller bolt 5 contacts with a mouthful mould 9, and it is firm that mouthful mould is installed, and is not loosening.
