Utility model content
Technical problem to be solved in the utility model is for above-mentioned the deficiencies in the prior art, a kind of plastics blow moulding extruder head plug is provided, this plug is provided with multiple splitter box interconnected vertically from top to bottom on outer wall, it forms the runner for fused materials circulation on plug outer wall, ensure that the smoothness that fused materials flows, impel fused materials more uniformly to carry out circumferential movement, ensure that wall thickness of plastic container is more even, intensity is better.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of plastics blow moulding extruder head plug, comprise the plug body of hollow, it is characterized in that, the outer wall of described plug body is disposed with feed well vertically from top to bottom, first splitter box, second splitter box, 3rd splitter box, vertical slot, helical shunt groove, first ring-type direct current groove and the second ring-type direct current groove, described feed well is horizontally set, the two ends of described feed well are communicated with two the first splitter boxs respectively, the two ends of described first splitter box are communicated with two the second splitter boxs respectively, the two ends of described second splitter box are communicated with two the 3rd splitter boxs respectively, the end of described 3rd splitter box is communicated with the vertical slot vertically arranged, the end of described vertical slot is communicated with helical shunt groove, the end of described helical shunt groove is connected with the first ring-type direct current groove, described first ring-type direct current groove parallels with the second ring-type direct current groove.
Above-mentioned a kind of plastics blow moulding extruder head plug, is characterized in that, described two the first splitter boxs, described two the second splitter boxs and described two the 3rd splitter boxs are all in splayed.
Above-mentioned a kind of plastics blow moulding extruder head plug, is characterized in that, the groove depth of described feed well, the first splitter box, the second splitter box, the 3rd splitter box, vertical slot and helical shunt groove reduces successively.
The utility model compared with prior art has the following advantages:
1, the utility model is provided with feed well, the first splitter box, the second splitter box, the 3rd splitter box, vertical slot, helical shunt groove, the first ring-type direct current groove and the second ring-type direct current groove vertically from top to bottom on plug outer wall, these grooves be connected form the runner for fused materials flowing on plug outer wall, 16 helical shunt grooves wherein on plug outer wall make fused materials repeatedly shear on plug outer wall, make the plasticizing effect of fused materials better, product quality is more excellent.
2, the groove depth of feed well of the present utility model, the first splitter box, the second splitter box, the 3rd splitter box, vertical slot and helical shunt groove reduces successively, both ensure that the fluency of fused materials in runner, impel again fused materials more uniformly to carry out circumferential movement, ensure that the wall thickness of Bulk plastic containers is more even.
3, helical shunt groove of the present utility model is connected with the first ring-type direct current groove, can effectively the fused materials in helical shunt groove be converged in the first ring-type direct current groove, and then flow into the second ring-type splitter box paralleled with the first ring-type direct current groove, fused materials is flowed in storage cavity more equably, form the parison of uniform wall thickness, eliminate the clinkering line of pipe embryo, avoiding Bulk plastic containers causes product to occur breaking the problem of leakage due to the existence of clinkering line, ensure that and use Bulk plastic containers safety in utilization.
Below in conjunction with drawings and Examples, the utility model is described in further detail.
