Abstract
The utility model discloses a mould for producing a plastic pipe, which comprises a hollow cylindrical mould head, a gasket and a polytetrafluoroethylene pipe; groove is arranged on the inner wall of the mould head along the circumferential direction; the polytetrafluoroethylene pipe is installed in the groove; the top of the polytetrafluoroethylene pipe is aligned with the top of the mould head; and the gasket is fixedly installed on the top of the mould head. The mould disclosed by the utility model has the advantages that: the outside surface of the pipe produced by using the mould disclosed by the utility model is smooth; furthermore, the size error of the pipe is low; therefore, the product yield can be increased, thus, the production cost is reduced.
Description
Technical field
The utility model relates to a kind of mould, is that a kind of production plastic tube is used mould specifically.
Background technology
Mould is to be used for the instrument of formed article, and this instrument is made up of various parts, and different dies is made up of different parts, and it mainly realizes the processing of article profile through the change of institute's moulding material physical state.Characteristics such as that PPR, PE pipe has is in light weight, corrosion-resistant, non-scaling, long service life, so their consumption is also more and more.All being the automatic production line that adopts when producing PPR, PE at present, is the hollow cylinder die head exporting mold matched with mixing extruder, and this die head adopts cast iron to process; The tube surface that comes out like this is coarse, and along with the rustization of cast iron, die head well damage; Make that die inner diameter is more and more nonstandard; Therefore the pipe sizing error of producing is big, and this just causes the product disqualification rate to rise, thereby increases production cost.
The utility model content
Goal of the invention: in order to overcome the deficiency of prior art, the purpose of the utility model be to provide a kind of rational in infrastructure, can make the smooth production plastic tube of plastic tube outer wall use mould.
Technical scheme: for realizing above-mentioned technical problem; The technical scheme that the utility model adopts is: a kind of production plastic tube is used mould; Comprise hollow cylinder die head, pad, polyfluortetraethylene pipe, on the inwall of said die head, also along the circumferential direction be provided with groove, said polyfluortetraethylene pipe is installed in the said groove; The top of said polyfluortetraethylene pipe flushes with the top of die head, and said spacers is installed in the top of said die head.
In order to make said polyfluortetraethylene pipe in groove, not produce displacement, the degree of depth of said groove is identical with the thickness of said polyfluortetraethylene pipe.
The internal diameter of said polyfluortetraethylene pipe equates with the external diameter of the plastic tube of being produced.
Beneficial effect: compared with prior art, the utility model has the advantages that: the outer tube surface that adopts the utility model to produce is smooth, and the pipe sizing error is little, and this just can improve product percent of pass, thereby reduces production costs.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done explanation further.
As shown in Figure 1: a kind of production plastic tube is used mould, comprises hollow cylinder die head 1, pad 2, polyfluortetraethylene pipe 3, on the inwall of die head 1, also along the circumferential direction is provided with groove 4, and the internal diameter of polyfluortetraethylene pipe 3 equates with the external diameter of the plastic tube of being produced; Polyfluortetraethylene pipe 3 is installed in the groove 4; The top of polyfluortetraethylene pipe 3 flushes with the top of die head 1; On pad 2, have at least 4 screwed holes; Have and the corresponding screwed hole in pad 2 screwed hole positions at the top of die head 1, through bolt 5 pad 2 is fixed on the top of die head 1 firmly, polyfluortetraethylene pipe 3 has suffered through the inner chamber that pad 2 and groove 4 just can be fixedly mounted on die head 1 like this.
The degree of depth of its further groove 4 is preferably identical with the thickness of polyfluortetraethylene pipe 3, and polyfluortetraethylene pipe 3 can not be moved in groove 4.
On the inwall of groove 4, also can be provided with screw thread, on the outer wall of polyfluortetraethylene pipe 3, be provided with and the suitable screw thread of groove 4 inner threads simultaneously, so just can more firmly polyfluortetraethylene pipe 3 be stuck in the groove 4.
The above only is the preferred implementation of the utility model.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also make some modification and improvement, these also should be regarded as belonging to the protection domain of the utility model.
