Description
Technical field
The present invention relates to the technical fields of extrusion die, and in particular to a kind of extruder head.
Background technology
The production of plastic pipe be by high viscosity molten resin under the promotion of extrusion pressure by head from die extrusion
It is molded pipe.The prior art it is widely used be spreader cooperation center bearing bracket design, pass through in melt uniformly distributed along spreader
Branch flow passage bottle neck chamfering after sectional area be gradually expanded, several branch flow passages of the runner from holder gradually expand and shape
At a few ribbon melts, then, each band-like melt connects together, and pipe is pressed into using the larger compression ratio of postposition.So
The pipe of production has following deficiency：1. it is in circumferentially that longitudinal direction weld mark occurs that band-like melt, which merges, so that the force of explosion of tubing declines,
Tubing slow crack growth in use simultaneously, it is easy to crack；2. spreader causes runner to separate and merges pressure increasing simultaneously again
Add and reduce, causes Pipes Density small, poor dimensional stability.3. melt is increased by pressure, the branch flow passage of spreader causes to melt
Body is increased by pressure, is not suitable for the larger melt of melt viscosity and is passed through, for example, ultra-high molecular weight polyethylene UHMWPE tubing or
Other composite pipes.
Taiwan Liu provides rich patent document CN2516337Y and devises helical flow path after branch flow passage, and weld mark is allowed to exist
Lock-out in spiral course, but this be it is a kind of after the method remedied, surface weld mark disappears, and still suffers from spiral inside
The weld bond of shape brings hidden danger to product quality.Then, spreader but not branch flow passage are designed how simple in structurely
Extruder head becomes the problem of industry extruder head general character urgently to be resolved hurrily.

The extruder head solves by following technical spirit and " has designed spreader how simple in structurely but do not had
Have the extruder head of branch flow passage " the technical issues of：
1) ring set ontology and filter house integral structure are solved by adopting 2.1 integral structure of filter house 2.2 and ring set ontology
Filter house needs fixed problem in extrusion channel, at the same also solve filter bypass body 2 with and couple the connection of baffle 1
Fixation problem is killed two birds with one stone.
2) integrated design balances tapering and shunting tapering respectively before and after filter house
Shunting tapering 2.4 is to play to carry out extruded cross section to filtered melt, to which the gas in melt be discharged, pressure
The effect of contracting fusant density, the tubing squeezed out in this way just can dense materials.If but filter house is only equipped with spreader in rear side
Portion, then before it is empty after the massive tail of band, move after center of gravity, part is easily deformed, and it is flat that one is then also designed on front side of filter house
Weighing apparatus tapering, which is balance elements, and the center of gravity for the part that moves forward is near filter house central part, another effect
It exactly does primary extruding in advance to melt flow stream, by the extruding twice before and after filter house, reaches exhaust effect.
3) inner concave conical of filter house and balance tapering and shunting taper fit
The inner concave conical of filter house and balance tapering and shunting taper fit, the first annular compression runner 21 of formation and the
Second ring compresses runner 31, is the compression exhaust of melt, while cylindrical melt flow channel being diverted in annular channel.
Compared with prior art, the present invention by the improvement in terms of three above, spreader but no tributary have been designed
The extruder head in road avoids after melt filtration during cylindrical melt flow channel is diverted to annular channel inevitably first
The type of flow closed after point, fundamentally solves the problems, such as the weld mark of spreader branch flow passage, the pipe fitting dense materials of extrusion,
Pore-free, weldless trace.
