Abstract
The utility model discloses a die assembly of an extruder, which has high quality, energy consumption conservation property and high production efficiency. The die assembly comprises a die body, a die sleeve arranged on the periphery of the die body and a baffle ring arranged at one end of the die sleeve, wherein the baffle ring is fixedly connected with the die sleeve; and the die body is made of polytetrafluoroethylene. The die assembly is used for forming the outer surface of a plastic pipe.
Description
Technical field
The utility model relates to a kind of extruder, relates in particular to a kind of for the mouth membrane module on the extruder.
Background technology
At PPR, need to use extruder in the production process of the pipelines such as PE, plastics become uniform melt by the extruder fusion plastification, enter mould after the further compacting of melt, because pipeline had both had inner surface, has again outer surface, thereby need to cooperatively interact by mouth membrane module and core assembly, just can produce qualified product, the effect of mouth membrane module is the outer surface of moulding pipeline, the mouth membrane module comprises a mouthful die body, the outside dimension of pipeline and surface quality are guaranteed that by dimensional accuracy and the quality of mouth die body a mouthful die body is steelwork usually, because molding runners need to have less frictional resistance in the pipeline forming process, and the coefficient of friction of steel is larger, and do not allow again in process of production the existence of any lubricant, thereby affect the Forming Quality of pipeline, increased simultaneously energy consumption; In addition, the mouth die body of steelwork produces ramming material in process of production easily, thereby need to regularly clear up, and clears up very trouble, thereby affects production efficiency.
The utility model content
The extruding dies assembly that the technical problems to be solved in the utility model provides a kind of good product quality, saves energy consumption, production efficiency is high.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises a mouthful die body, be located at mouthful die body periphery the mouth die sleeve, be located at the back-up ring of mouthful die sleeve one end, described back-up ring is fixedly connected with a mouthful die sleeve, described mouth die body is made by polytetrafluoroethylmaterial material.
The utility model compared with prior art has following obvious advantage and beneficial effect:
1, good product quality.Because the mouth die body in the utility model adopts polytetrafluoroethylmaterial material to make, polytetrafluoroethylmaterial material has good self-lubricating property, is conducive to improve the surface quality of extruding pipe material.
2, save energy consumption.Because the mouth die body in the utility model adopts polytetrafluoroethylmaterial material to make, the coefficient of friction of polytetrafluoroethylmaterial material is very low, and the shaping runner frictional resistance that mouthful die body is formed reduces greatly, effectively reduces extrusion pressure, reduce output power of motor, thereby saved energy consumption.
3, because the mouth die body in the utility model adopts polytetrafluoroethylmaterial material to make, and polytetrafluoroethylene (PTFE) has not viscosity, thereby can prolong cleaning cycle, and cleaning is also very easy, thereby has improved production efficiency.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
The specific embodiment
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail:
As shown in drawings: the utility model comprises mouthful die body 1, be located at mouthful die body 1 periphery mouth die sleeve 2, be located at the back-up ring 3 of mouthful die sleeve 2 one ends, back-up ring 3 is fixedly connected with a mouthful die sleeve 2, mouth die body 1 is made by polytetrafluoroethylmaterial material.
Claims (1)
1. extruding dies assembly, comprise a mouthful die body, be located at mouthful die body periphery the mouth die sleeve, be located at the back-up ring of mouthful die sleeve one end, described back-up ring is fixedly connected with a mouthful die sleeve, it is characterized in that described mouth die body made by polytetrafluoroethylmaterial material.
