Abstract
The utility model discloses a chlorinated polyvinyl chloride (CPVC) pipe extruding mould. The mould comprises a flange plate, wherein the flange plate is arranged on a handpiece of an extruding machine; a connecting piece is arranged on the flange plate; a handpiece body is arranged on the connecting piece; a mouth mould is arranged on the handpiece body; a mandril connector and a mandril are arranged in the handpiece body and the mouth mould; a heating rod is arranged in the mandril connector and the mandril; and an extruding mould cavity is formed between the mandril and the mouth mould. The CPVC pipe extruding mould is characterized in that the extruding mould cavity is in a bell mouth shape; a cavity body of the extruding mould cavity is gradually decreased from big to small; a split-flowing screen plate is arranged between the flange plate and the handpiece of the extruding machine; split-flowing small holes are formed in the split-flowing screen plate; a split-flowing plate is arranged between the connector and the handpiece body; split-flowing large holes are formed in the split-flowing plate; a split-flowing cone is arranged at one side of the split-flowing plate; the other side of the split-flowing plate is fixed with the mandril connector; a split-flowing cavity is formed among the split-flowing screen plate, the flange plate, the connecting piece, the split-flowing plate and the split-flowing cone and is communicated with the extruding mould cavity.
Description
Technical field
The utility model relates to the CPVC tube extrusion die, belongs to the mould of plastics field.
Background technology
The CPVC material is a kind of novel engineering plastics, and this material has the characteristics of the corrosion such as heat resistance, acid and alkali resistance, salt, oxidant, makes it be usually used in producing the tubing such as hot-water line, chemical industry carrier pipe and power pipe.Produce CPVC tubing and need the CPVC tube extrusion die, but the CPVC tube extrusion die of prior art mainly is that its shortcoming is that production efficiency is low with reference to original pvc pipe material extrusion die, and is inhomogeneous owing to being heated when material is extruded, easily turn black and be mingled with Jiao and expect, the yield rate of tubing is reduced.
Summary of the invention
The purpose of this utility model is the shortcoming that exists in order to overcome prior art, provides a kind of and enhances productivity, and is heated evenly when material is extruded, and guarantees the CPVC tube extrusion die of pipe finished rate.
The technical scheme of the utility model CPVC tube extrusion die is: comprise the ring flange that is installed on the cross-head, installation connecting element on the ring flange, handpiece body is installed on the connector, installing port mould on the handpiece body, in handpiece body and mouthful mould, be equipped with plug connector and plug, in plug connector and the plug heating rod is installed, form between plug and mouthful mould and extrude die cavity, it is characterized in that: the described die cavity of extruding is bell mouth shape, cavity is by reducing greatly gradually, the shunting sieve plate is installed between described ring flange and the cross-head, have the shunting aperture in the shunting sieve plate, between connector and the handpiece body flow distribution plate is installed, have the shunting macropore in the flow distribution plate, in flow distribution plate one side spreader is installed, flow distribution plate opposite side and plug connector fix, described shunting sieve plate, ring flange, connector, the chamber is shunted in formation between flow distribution plate and the spreader, shunts the chamber and extrude die cavity to communicate.
The utility model discloses a kind of CPVC tube extrusion die, by the shunting sieve plate is installed between ring flange and cross-head, open the shunting aperture in the shunting sieve plate, between connector and handpiece body, flow distribution plate is installed, have the shunting macropore in the flow distribution plate, when extruding, at first shunted first by the shunting aperture of shunting sieve plate by the material that cross-head transports, entering ring flange after the shunting mixes again again, it is heated evenly, then flow in the connector, made the material dispersion of gathering by spreader, when material flow is to the flow distribution plate, again material is shunted by the shunting macropore, be delivered at last the die cavity of extruding of bell mouth shape, form high pressure and extrude, with the material extrusion molding.This programme CPVC tube extrusion die, by the stroke that shunting sieve plate and flow distribution plate carry out second diffluence and integration, material obtains homogeneous heating in extrusion die, eliminates the part over-heating and produces burnt material and shadow, and the part complete defective such as heating not, guarantee the yield rate of tubing, make bell mouth shape and will extrude die cavity, cavity is by reducing greatly gradually, material extrusion place produces high pressure and extrudes, make tube extrusion speed fast, production efficiency is high, and pipe workpiece quality is good.
The utility model CPVC tube extrusion die, through being threaded, easy to connect, reliable between described plug connector and the plug.
Description of drawings
Fig. 1 is the structural representation of the utility model CPVC tube extrusion die.
The specific embodiment
The utility model relates to a kind of CPVC tube extrusion die, as shown in Figure 1, comprise the ring flange 1 that is installed on the cross-head, installation connecting element 2 on the ring flange, handpiece body 3 is installed on the connector, installing port mould 4 on the handpiece body, in handpiece body and mouthful mould, be equipped with plug connector 5 and plug 6, heating rod 7 is installed in plug connector 5 and the plug 6, form between plug and mouthful mould 4 and extrude die cavity 8, it is characterized in that: the described die cavity 8 of extruding is bell mouth shape, cavity is installed shunting sieve plate 9 by reducing greatly gradually between described ring flange 1 and the cross-head, have shunting aperture 10 in the shunting sieve plate, flow distribution plate 11 is installed between connector 2 and the handpiece body 3, have shunting macropore 12 in the flow distribution plate, in flow distribution plate one side spreader 13 is installed, flow distribution plate 11 opposite sides and plug connector 5 fix, described shunting sieve plate 9, ring flange 1, connector 2, chamber 14 is shunted in formation between flow distribution plate 11 and the spreader 13, shunts the chamber and extrude die cavity 8 to communicate.By shunting sieve plate 9 is installed between ring flange 1 and cross-head, open shunting aperture 10 in the shunting sieve plate, flow distribution plate 11 is installed between connector 2 and handpiece body 3, have shunting macropore 12 in the flow distribution plate, when extruding, at first shunted first by the shunting aperture 10 of shunting sieve plate 9 by the material that cross-head transports, enter again ring flange 1 after the shunting and again mix, it is heated evenly, then flow in the connector 2, made the material dispersion of gathering by spreader 13, when material flow is to the flow distribution plate 11, again material is shunted by shunting macropore 12, what be delivered at last bell mouth shape extrudes die cavity 8, the formation high pressure is extruded, with the material extrusion molding.This programme CPVC tube extrusion die, by the stroke that shunting sieve plate 9 and flow distribution plate 11 carry out second diffluence and integration, material obtains homogeneous heating in extrusion die, eliminates the part over-heating and produces burnt material and shadow, and the part complete defective such as heating not, guarantee the yield rate of tubing, make bell mouth shape and will extrude die cavity 8, cavity is by reducing greatly gradually, material extrusion place produces high pressure and extrudes, make tube extrusion speed fast, production efficiency is high, and pipe workpiece quality is good.Connect through screw thread 15 between described plug connector 5 and the plug 6, easy to connect, reliable.
