Description
Technical field
The utility model belongs to tube forming field, is related to a kind of head of extruder used by polyvinyl piping materials extrusion molding
Device.
Background technology
High density polyethylene (HDPE) (HDPE) is that a kind of crystallinity is high, nonpolar thermoplastic resin, can be molded into by extrusion
Type technique prepares the products such as tubing, electric wire, cable, flexible pipe.For polyvinyl piping materials extruding production line, extruder is that its is heavy
One of core wanted, and head, as a part for extruder, its main function is to be changed into the plastic melt of rotary motion
Parallel lines is moved, and assigns the shape needed for the necessary briquetting pressure of melt and product, therefore, head for melt into
The quality of type and product plays highly important effect.
At present, in HDPE extruders head is often made of mould steel, and mould steel is being processed into head die by forging
After tool, there is the defects such as coefficient of friction height so that the tubing surfaces externally and internally finish of preparation is poor, it is difficult to reach the requirement of client.
Simultaneously as, it is necessary to change head during different tube diameters tubing is produced, and may also can cause machine during changing
There are the defects such as breach in head surface, influences the quality of product.For above-mentioned situation, remake extrusion die if taking and change
Method, then can greatly improve production cost, and the process is also relatively complicated, influence the production efficiency of product.
The content of the invention
The purpose of this utility model is to provide inside and outside a kind of frame head apparatus of polyvinyl piping materials extruder, the tubing of preparation
Wall surface is smooth, easy to use, reduces cost.
The technical scheme that the utility model solves the technical problem is：
A kind of frame head apparatus of polyvinyl piping materials extruder, including mouth mold, plug, the first pad, the second pad, the first ring
The surface of shape pressing plate, the second annular pressing plate, the first fastening bolt and the second fastening bolt, the first pad and the second pad is set respectively
There are the first fastening bolt holes and the second fastening bolt holes, the first fastening bolt successively passes through first annular pressing plate and the first pad
The first fastening bolt holes after be located by connecting with mouth mold, the second fastening bolt successively pass through the second annular pressing plate and the second pad
The second fastening bolt holes after be located by connecting with plug, the working face of the first pad and the second pad be respectively equipped with first boss and
Second boss, wherein, the first pad and the second pad are polytetrafluoroethylmaterial material, and first boss and second boss are triangle
Shape boss, its interior angle is less than 1.5 °, or, first boss and second boss are arc surface boss, the first pad and the second pad
The thickness of piece is identical, and in same perpendicular, the thickness of first annular pressing plate and the second annular pressing plate is identical, and in same
One perpendicular.
Beneficial effect using the utility model frame head apparatus polyethylene extrusion tubing is, due to polytetrafluoroethylene (PTFE) and poly-
Ethene coefficient of friction is close, polythene material surface can be played using the pad prepared by it and preferably smooth effect, and
The first boss of first pad work surface and the second pad work surface, second boss can form further shaping to plastic melt
Pressure, enables the extrusion of tubing continuous-stable, so for preparing that inside and outside wall surface gloss gets well and conform to quality requirements is poly-
Ethene tubing, meanwhile, frame head apparatus assembling is simple, easy to use, it is to avoid other additives are used in polyethylene raw material,
High degree reduces production cost.
