Abstract
The invention discloses a kind of mould structure for producing PE combustion gas tubing, it includes core roller and main mould, pipe fitting is arranged between described core roller and described main mould, it it is the cylindrical section of cylindrical structure in the middle part of described core roller, being provided with convex shoulder on described cylindrical section, it is the first inclined-plane, end face and the second inclined-plane that described convex shoulder sets gradually from top to bottom；Described first inclined-plane is the most outward-dipping, and described second inclined-plane slopes inwardly from top to bottom, and described end face is vertical plane；The side of described main mould is vertical plane.The PE combustion gas tubing that the mould provided by the present invention is processed, sawing machine is used to separate after manufacture, the parting surface surface condition of pipe fitting is good, the surplus gone mutually on height can be reduced, convenient formation, save the use of material, save raw material about 14～18% than conventional rectangular pipe fitting, save the consumption of the combustion gas homenergic of half；Pipe fitting entirety surplus is little, reduces last machining time, improves efficiency.
Description
Technical field
The invention belongs to a kind of mould structure for producing PE combustion gas tubing.
Background technology
PE combustion gas tubing shape of product is complicated, not easy-formation.At present, traditional PE combustion gas tubing processing mode typically uses
Conventional rectangular manufactures, and machines (reducing follow-up machining allowance, increase through hardening layer depth), at reheating before carrying out heat treatment
Reason, the most machining.Owing to the internal diameter of raceway has bigger gradient, this gradient adds the difficulty of molding.Prior art
Rectangle manufacture use material a lot, cause wasting material, processing cost high, in turn result in the pipe fitting price of raceway also
High.
Summary of the invention
The technical problem to be solved in the present invention is to overcome existing defect, it is provided that a kind of convenient formation, material-saving and being processed into
This low mould structure for producing PE combustion gas tubing.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
A kind of mould structure for producing PE combustion gas tubing of the present invention, it includes core roller and main mould, and pipe fitting is arranged at institute
State between core roller and described main mould, be the cylindrical section of cylindrical structure in the middle part of described core roller, described cylindrical section is provided with convex shoulder
Portion, it is the first inclined-plane, end face and the second inclined-plane that described convex shoulder sets gradually from top to bottom；Described first inclined-plane from top to bottom to
Outer incline, described second inclined-plane slopes inwardly from top to bottom, and described end face is vertical plane；The side of described main mould is vertical plane.
Further, described first inclined-plane is 22 °～36 ° with the angle of vertical direction.
Further, described second inclined-plane is 22 °～36 ° with the angle of vertical direction.
Further, described first inclined-plane is equal with the length on described second inclined-plane, and is four times of described end face length.
The present invention is reached to provide the benefit that:
The present invention, according to the feature of raceway, designs mould, and the gradient making raceway internal diameter is symmetrical, the mould provided by the present invention
The PE combustion gas tubing that tool processes, uses sawing machine to separate after manufacture, the parting surface surface condition of pipe fitting is good, it is possible to reduce on height
The surplus gone mutually, convenient formation, save the use of material, save raw material about 14～18% than conventional rectangular pipe fitting, save
The consumption of the combustion gas homenergic of half；Pipe fitting entirety surplus is little, reduces last machining time, improves efficiency.
Accompanying drawing explanation
Accompanying drawing is for providing a further understanding of the present invention, and constitutes a part for description, with the reality of the present invention
Execute example together for explaining the present invention, be not intended that limitation of the present invention.In the accompanying drawings:
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the structural representation of main mould；
Fig. 3 is the structural representation of core roller.
Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are illustrated, it will be appreciated that preferred reality described herein
Execute example be merely to illustrate and explain the present invention, be not intended to limit the present invention.
As shown in Figure 1 to Figure 3, a kind of mould structure for producing PE combustion gas tubing of the present invention, it includes core roller 1 and master
Mould 2, pipe fitting 3 is arranged between described core roller 1 and described main mould 2, is the cylindrical section 4 of cylindrical structure in the middle part of described core roller 1, institute
Stating and be provided with convex shoulder 5 on cylindrical section 4, it is the first inclined-plane 501, end face 502 and that described convex shoulder 5 sets gradually from top to bottom
Two inclined-planes 503；Described first inclined-plane 501 is the most outward-dipping, and described second inclined-plane 503 slopes inwardly from top to bottom, institute
State end face 502 for vertical plane；The side 201 of described main mould 2 is vertical plane.
Described first inclined-plane 501 is 22 °～36 ° with the angle of vertical direction.
Described second inclined-plane 503 is 22 °～36 ° with the angle of vertical direction.
Described first inclined-plane 501 is equal with the length on described second inclined-plane 503, and is four times of described end face 502 length.
The present invention, according to the feature of raceway, designs mould, and the gradient making raceway internal diameter is symmetrical, the mould provided by the present invention
The PE combustion gas tubing that tool processes, uses sawing machine to separate after manufacture, the parting surface surface condition of pipe fitting is good, it is possible to reduce on height
The surplus gone mutually, convenient formation, save the use of material, save raw material about 14～18% than conventional rectangular pipe fitting, save
The consumption of the combustion gas homenergic of half；Pipe fitting entirety surplus is little, reduces last machining time, improves efficiency.
Finally it is noted that the foregoing is only the preferred embodiments of the present invention, it is not limited to the present invention,
Although being described in detail the present invention with reference to previous embodiment, for a person skilled in the art, it still may be used
So that the technical scheme described in foregoing embodiments to be modified, or wherein portion of techniques feature is carried out equivalent.
All within the spirit and principles in the present invention, any modification, equivalent substitution and improvement etc. made, should be included in the present invention's
Within protection domain.
