Abstract
The utility model discloses a pipe bending mold of a plastic pipe. The pipe bending mold comprises an upper mold and a lower mold, wherein the mold surface of the side surface of the upper mold is a convex arc surface; the shape of the arc-shaped surface is the shape of the bent plastic pipe; the corresponding side surfaces of the lower mold and the upper mold are respectively provided with an arc surface matched with the bent plastic pipe; both the upper mold and the lower mold comprise an upper mold shell and a lower mold shell which are respectively and internally provided with a cavity; the positions of the arc surfaces of the upper mold shell and the lower mold shell are respectively provided with an opening; the cavities of the upper mold shell and the lower mold shell are internally filled with cement concrete; the cement concrete at the openings of the upper mold shell and the lower mold shell form smooth arc surfaces. The pipe bending mold disclosed by the utility model has the advantages that the cement concrete is adopted as a main body of the mold, and the smooth arc surfaces of the cement concrete are easily formed by manual work; the cost is low, the effect is good and the promotion value is larger.
Description
Technical field
The utility model relates to a kind of swan neck system technical field, especially plastic tube bend pipe mould.
Background technology
With in, civil building and electric equipment, be widely used plastic pipe, especially the PVC plastic tube of various diameters in various works, for upper and lower conduit and blast pipe, cable penetration pipe etc.Send out trend according to pipeline, tube bending must be become to suitable angle.Used pipe bender adopts the supporter such as spring steel wire, rubber bar of fit diameter is penetrated in pvc pipe, or with sandstone, spring steel wire as filler, on heater, be heated, then, form by required angular bend.
Current plastic tube bend pipe mould is as a kind of tube bender of plastic tube of the Chinese utility model patent ZL200620114554.5 of inventor's mandate, the structure of its mould is for comprising upper die and lower die, the die face of patrix side is the cambered surface that is protrusion, the shape that is shaped as bent plastic tube of arcwall face, the corresponding side surface of counterdie and patrix is respectively equipped with the cambered surface matching with bent plastic tube.This structure adopts the material of cast iron conventionally, and its cost is high.Also have inventor to adopt steel plate materials to be welded, but, upper die and lower die and cambered surface make of steel plate, its shape be difficult to processing, therefore its structure can not get promotion and application.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, provides cost low, upper die and lower die and the easily plastic tube bend pipe mould of processing of cambered surface.
The technical scheme that the technical problem that the utility model solves adopts is:
A kind of plastic tube bend pipe mould, comprise upper die and lower die, the die face of patrix side is the cambered surface that is protrusion, the shape that is shaped as bent plastic tube of arcwall face, the corresponding side surface of counterdie and patrix is respectively equipped with the cambered surface matching with bent plastic tube, it is characterized in that upper die and lower die are provided with upper shuttering and the lower formwork of cavity in comprising respectively, the cambered surface place opening of upper shuttering and lower formwork, filling concrete concrete in the cavity of upper shuttering and lower formwork, the cement concrete of the opening part of upper shuttering and lower formwork forms smooth cambered surface.
The utility model adopts the inserts of cement concrete as upper shuttering and lower formwork, greatly reduces the cost of mould.Adopt cement concrete as the die face that bends plastic tube, in the time making, process the cambered surface of the opening part of upper shuttering and lower formwork by cement mortar, be very easy to moulding, difficulty of processing is low, and the material of cement concrete is high temperature resistant, is not easy to occur metaboly.
Above-mentioned upper shuttering and lower formwork are respectively upper shuttering and the lower formwork of steel plate materials.Upper shuttering of the present utility model and lower formwork adopt steel plate materials, the steel plate of each is welded to each other, and inserts in the cavity of upper shuttering and lower formwork after cement concrete mortar stirs, the artificial smooth arc-shaped surface that is very easy to form cement concrete, after theing cement solidifies, complete.
When use, first the plastic tube workpiece that is provided with the filling supporters such as sandstone, by steam preheating, after pvc pipe is heated, manual or electronic startup patrix, while making pvc pipe be bent to setting or the angle requiring and radian between the cambered surface of upper die and lower die, close air intake valve, open cooling water valve, cooling water enters the pvc pipe of moulding, be cooled to rapidly room temperature, complete bend pipe operation.
The beneficial effects of the utility model are: the utility model adopts the main body of cement concrete as mould, the artificial smooth arc-shaped surface that is very easy to form cement concrete, and its cost is low, effective, has larger promotional value.
Brief description of the drawings
Below in conjunction with drawings and Examples, utility model is further illustrated.
Fig. 1 is the structural representation of the utility model embodiment.
In figure: 1, patrix 2, counterdie 3, concrete 11, upper shuttering 21, lower formwork 31, cambered surface.
Detailed description of the invention
In Fig. 1, a kind of plastic tube bend pipe mould, comprise patrix 1 and counterdie 2, patrix 1 and counterdie 2 are positioned on work top, counterdie 2 is fixed on work top, corresponding patrix 1 be positioned at counterdie 2 before, patrix 1 is provided with the power set that drive patrix 1 to move to counterdie 2, in comprising respectively, patrix 1 and counterdie 2 be provided with upper shuttering 11 and the lower formwork 21 of cavity, upper shuttering 11 and lower formwork 21 are welded with steel plate materials respectively, filling concrete concrete 3 in the cavity of upper shuttering 11 and lower formwork 21, the cement concrete 3 of the opening part of upper shuttering 11 and lower formwork 21 forms smooth cambered surface 31, the die face of patrix 1 side is the cambered surface 31 that is protrusion, the shape that is shaped as bent plastic tube of cambered surface 31, counterdie 2 is respectively equipped with the corresponding side surface of patrix 1 cambered surface 31 matching with bent plastic tube.
Upper shuttering 11 of the present utility model and lower formwork 21 adopt steel plate materials, the steel plate of each is welded to each other, and inserts in the cavity of upper shuttering 11 and lower formwork 21 after cement concrete mortar stirs, the artificial smooth arc-shaped surface that is very easy to form cement concrete, after theing cement solidifies, complete.Its difficulty of processing is low, and the material of cement concrete is high temperature resistant, is not easy to occur metaboly.
Finally, it is also to be noted that, what more than enumerate is only specific embodiment of the utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive or associate from disclosed content of the present utility model, all should think protection domain of the present utility model.
