Abstract
The utility model discloses a T-shaped polytetrafluoroethylene tube forming mold. The T-shaped polytetrafluoroethylene tube forming mold comprises an outer mold and also comprises an upper pressing piece, a lower pressing piece and a core rod, wherein an inner cavity of the outer mold forms a molding cavity together with the upper pressing piece and the lower pressing piece; the molding cavity is matched with a T-shaped tube in shape; the core rod penetrates through the upper pressing piece and the lower pressing piece and extends out of the upper pressing piece; a pressurizing tube is also arranged on the upper pressing piece; the core rod is sleeved with the pressurizing rod; and the lower end face of the pressurizing rod is in contact with the upper end face of the upper pressing piece. By utilizing the forming mold having the abovementioned structure, the T-shaped tube can be formed by one-time compression molding; the forming mold is simple in structure, low in processing cost, low in waste of raw materials and suitable for mass production; the raw materials are greatly saved; and the production efficiency is improved. In addition, a manufactured T-shaped tube product is uniform in density distribution and high in quality.
Description
Technical field
The utility model relates to a kind of mould, the mould of the T-shaped pipe of especially a kind of polytetrafluoroethylene (PTFE).
Background technology
Polytetrafluoroethylene (PTFE) is a kind of artificial synthesized polymer material that has used fluorine to replace all hydrogen atoms in polyethylene.This material has the feature of antiacid alkali resistant, anti-various organic solvents, is dissolved in hardly all solvents.Meanwhile, polytetrafluoroethylene (PTFE) has resistant to elevated temperatures feature, and its coefficient of friction is extremely low, so after can making lubrication, also become the desirable coating of water pipe internal layer.
Because polyflon is Powdered, when compressing, almost there is no mobility, if fruit is difficult to moulding with general mould compacting.So existing method is generally first to make cylinder, then secondary machine moulding.Its operation is various, and waste of raw materials is large, and goods cost is high.
Utility model content
For the technical problem of above-mentioned existence, the utility model provides a kind of polytetrafluoroethylene (PTFE) T-shaped pipe shaping mould, polyflon time processing can be pressed into T-shaped pipe.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
The T-shaped pipe shaping mould of polytetrafluoroethylene (PTFE), comprises external mold, also comprises a upper holder block, a lower lock block and a plug; The inner chamber of described external mold and upper holder block and lower lock block surround forming cavity; The shape of described forming cavity and T-shaped pipe profile match; Described plug runs through described plug and runs through upper and lower briquetting, and extends upper holder block; On described upper holder block, be also provided with a forcing pipe, described in add pressure bar and be placed on plug, and its lower surface contacts with upper holder block upper surface.
Usefulness of the present utility model is: utilize the mould with said structure, and compressing T-shaped pipe once, it is simple in structure, processing cost is low, and the mould that wastage of material is little is applicable to batch production, greatly save raw material, improved production efficiency.And the T-shaped tubing products Density Distribution of making is even, and quality is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Mark in figure: 1 external mold, 2 upper holder blocks, 3 lower lock blocks, 4 forcing pipes, 5 forming cavities, 6 plugs.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in detail.
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1:
The utility model comprises external mold 1, also comprises a upper holder block 2, lower lock block 3 and a plug 6; The inner chamber of described external mold 1 and upper holder block 2 and lower lock block 3 surround forming cavity 5; The shape of described forming cavity 5 and T-shaped pipe profile match; Described plug 6 runs through lower lock block 3, upper holder block 2, and extends upper holder block 2; On described upper holder block 2, be also provided with a forcing pipe 4, described in add pressure bar 4 and be placed on plug 6, and its lower surface contacts with upper holder block 2 upper surfaces.
The upper and lower end face of upper holder block 2 and the T-shaped pipe of lower lock block 3 moulding, external mold 1 inner chamber moulding outer surface remainder, the T-shaped tube cavity of core rod forming.For the time upper holder block 2 of suppressing, be positioned among external mold 1 inner chamber, increase a forcing pipe 4 and conveniently upper holder block 2 is exerted pressure, the length of forcing pipe 4 can change according to the condition of production.This mould adopts secondary charging when producing T-shaped pipe, once finished product is made in compressing a, demoulding.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
