Abstract
The invention discloses a high-speed CPVC (chlorinated polyvinyl chloride) pipe extrusion mould which comprises a flange plate and a head connecting body which are mounted on the head of an extruder, wherein a mouth mould is mounted in the mouth part of the head connecting body; a mouth mould pressing plate is mounted outside the mouth mould and fixed with the head connecting body through a bolt; a core rod is mounted in the mouth mould; an extrusion mould cavity is formed between the core rod and the mouth mould; the high-speed CPVC pipe extrusion mould is characterized in that: a distribution plate is mounted in the head connecting body; a distribution hole is formed in the distribution plate; the distribution plate is internally connected with a distribution cone; the distribution cone is connected with the core rod through a stud; a distribution cavity is formed between the distribution cone and the head connecting body; the distribution cavity, the distribution hole and the extrusion mould cavity are communicated with each other; and the extrusion mould cavity is of a bell mouth shape and turns smaller gradually. According to the invention, the extrusion mould cavity is of a bell mouth shape and turns smaller gradually to form high-pressure extrusion, thereby realizing fast pipe extrusion and improving the production efficiency.
Description
Technical field
The present invention relates to the CPVC pipe mold that a kind of high speed is extruded, belong 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 pvc pipe material extrusion die, and production efficiency is low.
Summary of the invention
The objective of the invention is provides a kind of extruded velocity fast in order to overcome the shortcoming of prior art, the high speed CPVC tubing extrusion die that production efficiency is high.
The technical scheme of high speed CPVC tubing extrusion die of the present invention 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 mouth mould, the mouth moulded board fixes through screw and head connector, in the mouth mould plug is installed, form between plug and mouthful mould and extrude die cavity, 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, the 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 invention 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, 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, forms high pressure and extrudes, make the tubing extruded velocity fast, production efficiency improves.
High speed CPVC tubing extrusion die of the present invention, 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 a high speed CPVC tubing extrusion die structural representation of the present invention.
The specific embodiment
The present invention relates to a kind of high speed CPVC tubing extrusion die, as shown in Figure 1, comprise the ring flange 1 and the head connector 2 that are installed on the cross-head, installing port mould 9 in the oral area of head connector 2, mouth mould 9 outer installing port moulded boards 7, mouth moulded board 7 fixes through screw 11 and head connector 2, in the mouth mould 9 plugs 8 are installed, form between plug 8 and mouthful mould 9 and extrude die cavity 12, it is characterized in that installing in the described head connector 2 flow distribution plate 4, 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, 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, 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 bell mouth shape by dwindling greatly gradually, and material flows into the shunting chamber 14 from cross-head, flow 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.
