Abstract
The utility model relates to a kind of for Gas Pipe internal surface of bloom polishing assembly, comprise plug and mouth mould, a prolongation guide pin bushing is coaxially fixedly mounted with in the end of plug dip section, this prolongation guide pin bushing and plug dip section isometrical, on this prolongation guide pin bushing, coaxial sleeve is equipped with a pipe material inner wall polishing ring, and mouth mould inwall is coaxially installed with outer pipe wall polishing ring.At melting charge by mouth mould and plug process; internal surface of pipe and outer surface obtain friction respectively by pipe material inner wall polishing ring and outer pipe wall polishing ring; half-formed internal surface of pipe and outer surface is made all to obtain friction thus; thus make surface more smooth; the buildup when avoiding producing and the shutdown that causes reset restarts, and meanwhile, reduces the pipe material inner wall flow-disturbing and impedance produced; improve the transporting velocity of the energy, thus save the energy.
Description
Technical field
The utility model belongs to Gas Pipe production equipment field, especially a kind of for PE Gas Pipe internal surface of bloom polishing assembly.
Background technology
In Gas Pipe manufacture process, the shaping needs of pipe by mouth mould to coordinate with plug assemble after form melting charge flow channel cavity realize, it shows as: cavity volume reduces gradually and melting charge is under pressure, shaping pipe when extruding in the flat segments cavity of mouth mould and plug.
The internal diameter of mouth mould is shaping Gas Pipe goods external diameter surface size parts, but when melting charge flows through mouthful mould and core rod end hole cavity, often because transporting velocity fluctuation or density variation cause feeding uneven, not only have impact on the shaping rear smoothness of inner wall of pipe, add pipe internal resistance, thus energy consumption when adding use, more seriously easily cause local buildup serious.Must repairing be shut down, then charging again, allow mouthful mould and plug again operate, waste time and energy, reduce production efficiency; On the other hand, to a certain degree can avoid buildup in Shangdi although pressurizeed by pump or carry out screening to charging, add that manufactures parts thus, not only need reasonable installation, more need timely debugging, add hand labor cost.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provide that a kind of structure is simple, design science and avoid buildup for PE Gas Pipe internal surface of bloom polishing assembly.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of for PE Gas Pipe internal surface of bloom polishing assembly, comprise plug and mouth mould, a prolongation guide pin bushing is coaxially fixedly mounted with in the end of plug dip section, this prolongation guide pin bushing and plug dip section isometrical, on this prolongation guide pin bushing, coaxial sleeve is equipped with a pipe material inner wall polishing ring, and mouth mould inwall is coaxially installed with outer pipe wall polishing ring.
And described pipe material inner wall polishing ring and outer pipe wall polishing ring are concentric arrays.
And, coaxially on described prolongation guide pin bushing be uniformly provided with multiple screw, extend guide pin bushing and fixedly mounted by the plurality of screw engagement construction bolt and plug dip section.
Advantage of the present utility model and good effect are:
1, the utility model passes through in mouth mould and plug process at melting charge; internal surface of pipe and outer surface obtain friction respectively by pipe material inner wall polishing ring and outer pipe wall polishing ring; half-formed internal surface of pipe and outer surface is made all to obtain friction thus; thus making surface more smooth, the buildup when avoiding producing and the shutdown that causes reset restarts.
2, the utility model is by carrying out scientific and effective to core rod end and reasonably transforming, and reduces the pipe material inner wall flow-disturbing and impedance produced, improves the transporting velocity of the energy, thus saved the energy.
Accompanying drawing explanation
Fig. 1 is the structural representation of plug dip section in the utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the longitudinal section view that in the utility model, plug dip section coordinates with mouth mould.
Detailed description of the invention
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of for PE Gas Pipe internal surface of bloom polishing assembly, comprise plug 4 and mouth mould 6, one end of plug is coaxially stretched in mouthful mould, form injection moulding die cavity with mouth mould and produce tubing, coaxially be fixedly mounted with a prolongation guide pin bushing 1 in the end of plug dip section 3, this prolongation guide pin bushing and plug dip section isometrical, on this prolongation guide pin bushing coaxial sleeve be equipped with one pipe material inner wall polishing ring 2, mouth mould inwall is coaxially installed with outer pipe wall polishing ring 7, and pipe material inner wall polishing ring and outer pipe wall polishing ring are concentric arrays.
Extend and coaxially on guide pin bushing be uniformly provided with multiple screw 5, extend guide pin bushing and fixedly mounted by the plurality of screw engagement construction bolt and plug dip section.
Operation principle of the present utility model is:
At melting charge by mouth mould and plug process, internal surface of pipe and outer surface obtain friction respectively by pipe material inner wall polishing ring and outer pipe wall polishing ring, half-formed internal surface of pipe and outer surface is made all to obtain friction thus, thus make surface more smooth, while avoiding buildup, reduce the pipe material inner wall flow-disturbing and impedance produced, improve the transporting velocity of the energy, thus saved the energy.
Although disclose embodiment of the present utility model and accompanying drawing for the purpose of illustration, but it will be appreciated by those skilled in the art that: in the spirit and scope not departing from the utility model and claims, various replacement, change and amendment are all possible, therefore, scope of the present utility model is not limited to the content disclosed in embodiment and accompanying drawing.
