Abstract
The utility model discloses a reinforced polymer plasticizing device of a CPVC (Chlorinated Polyvinyl Chloride) pipe extrusion die. The reinforced polymer plasticizing device is characterized by comprising a reinforced polymer plasticizing template, wherein fixing holes are formed in the template; a boss is arranged on one side of the template; an extrusion molding hole is formed in the template and the boss; the extrusion molding hole comprises an inlet, a necking opening and an outlet; the diameter of the necking opening is less than that of the inlet and that of the outlet; when materials are input from the inlet of the extrusion molding hole, as the pore diameter of the inlet is large and the diameter from the inlet to the necking opening is reduced gradually, the materials around the inlet are blocked by the inner wall of the inlet so as to be conveyed to the inlet center and extruded by the materials in the inlet center, and thus the materials are extruded out of the necking opening under high pressure; the extruded materials are compact and excellent in mechanical property; the materials are heated evenly in the die; the defect that one part is excessively heated to produce coke and shadow while one part is not heated completely can be eliminated, so that the yield of the pipes can be ensured.
Description
Technical field
The utility model relates to CPVC tube extrusion die, particularly relates to the enhancing polymer plasticizing apparatus of CPVC tube extrusion die.
Background technology
CPVC(chliorinated polyvinyl chloride) material is a kind of novel engineering plastics, and this material has the feature 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 CPVC tube extrusion die, but the CPVC tube extrusion die of prior art is mainly with reference to original pvc pipe material extrusion die, its shortcoming is that production efficiency is low, when extruding, material strengthens polymer plasticizing owing to not passing through, poor mechanical property, be heated inhomogeneous, easily turn black and be mingled with burnt material, the yield rate of tubing is reduced.
Summary of the invention
The purpose of this utility model is the shortcoming existing in order to overcome prior art, provides a kind of mechanical property of extruded material good, when material is extruded, is heated evenly, and guarantees the enhancing polymer plasticizing apparatus of the CPVC tube extrusion die of pipe finished rate.
The technical scheme of the enhancing polymer plasticizing apparatus of the utility model CPVC tube extrusion die is: it is characterized in that comprising the template that increases polymer plasticizing, in template, have fixing hole, in template one side, be shaped with boss, in template and boss, be shaped with extrusion molding hole, described extrusion molding hole comprises entrance, reducing and outlet, and reducing aperture is less than the aperture of entrance and exit.
The utility model discloses a kind of enhancing polymer plasticizing apparatus of CPVC tube extrusion die, by the template that increases polymer plasticizing is set in CPVC tube extrusion die, when material is inputted from the entrance in extrusion molding hole, because aperture, porch is large, and entrance to the aperture of reducing dwindles gradually, therefore at entrance material around, being subject to stopping to entrance center place of entrance inwall carries, and form extruding with the material of entrance center, material is extruded from reducing high pressure, the material of extruding is finer and close, mechanical property is better, material obtains homogeneous heating in mould, eliminate part over-heating and produce burnt material and shadow, and the part defect such as heating completely not, guarantee the yield rate of tubing.
The enhancing polymer plasticizing apparatus of the utility model CPVC tube extrusion die, the inwall of described entrance, reducing and outlet is arc inner wall.The inwall of described entrance, reducing and outlet is linear pattern inwall.
Accompanying drawing explanation
Fig. 1 is that the master of the enhancing polymer plasticizing apparatus of CPVC tube extrusion die looks schematic diagram;
Fig. 2 is the structural representation that the enhancing polymer plasticizing apparatus of CPVC tube extrusion die is arc inner wall;
Fig. 3 is that the enhancing polymer plasticizing apparatus of CPVC tube extrusion die is the structural representation of linear pattern inwall.
The specific embodiment
The utility model relates to a kind of enhancing polymer plasticizing apparatus of CPVC tube extrusion die, as shown in Fig. 1-Fig. 3, it is characterized in that: comprise the template 1 that increases polymer plasticizing, in template, have fixing hole 2, in template one side, be shaped with boss 3, in template and boss, be shaped with extrusion molding hole 4, described extrusion molding hole 4 comprises entrance 5, reducing 6 and exports 7, and reducing aperture is less than the aperture of entrance and exit.By the template 1 that increases polymer plasticizing is set in CPVC tube extrusion die, when material is inputted from the entrance 5 in extrusion molding hole 4, because aperture, porch is large, and entrance to the aperture of reducing 6 dwindles gradually, therefore at entrance material around, being subject to stopping to entrance center place of entrance inwall carries, and form extruding with the material at entrance 5 centers, material is extruded from reducing 6 high pressure, the material of extruding is finer and close, mechanical property is better, material obtains homogeneous heating in mould, eliminate part over-heating and produce burnt material and shadow, and the part defect such as heating completely not, guarantee the yield rate of tubing.Described entrance 5, reducing 6 and to export 7 inwall be arc inner wall.Described entrance 5, reducing 6 and to export 7 inwall be linear pattern inwall.
