Abstract
The utility model belongs to the technical field of pipeline injection-mold dies, and in particular relates to a die for a hollow spiral sound attenuation pipe. A large mouth molded board and a mouth molded board are arranged on the molding section of the die. The die is characterized in that the large mouth molded board is provided with an inner wall adjusting device, and the mouth molded board is provided an outer wall adjusting device. The die provided by the utility model has adjustable inner and outer walls aiming at the special design of uneven wall thickness of two layers of pipes, and can ensure the evenness of the thickness of the pipe wall. The die provided by the utility model is compact in structure and easy to operate, is suitable for being used as the molding die of similar products, has very high stability in production, and can be used for effectively reducing the defective index in production.
Description
Technical field
The utility model belongs to pipeline injection mold technical field, particularly a kind of mould of hollow spiral hush pipe material.
Background technology
In the prior art, melt differs because melting the material mobility status in extrusion die profiled section zone when producing pipeline, the imperfectly equalized situation of temperature, hollow spiral hush pipe material wall thickness can not be guaranteed effectively that percent defective is high in the production process, dismounting repairs a die frequently, and production efficiency is low.
The utility model content
Problem to be solved in the utility model is to overcome the deficiencies in the prior art, and a kind of mould that can solve the hollow spiral hush pipe material hollow spiral hush pipe material that inside and outside wall thickness is effectively guaranteed when producing is provided.
For achieving the above object, the technical solution of the utility model is:
The utility model provides a kind of mould of hollow spiral hush pipe material, comprises large mouthful of moulded board, mouthful moulded board in the mould molding section, it is characterized in that: be provided with the inwall adjusting device at large mouthful of moulded board place.
In the such scheme, described inwall adjusting device comprises the large mouth tight screw of mold pressing and the inwall adjustment screw that is fixed on the large mouthful of moulded board.
Further, in the such scheme, the place is provided with the outer wall adjusting device at the mouth moulded board.
In the such scheme, described outer wall adjusting device comprises mouth moulded board housing screw and the outer wall adjustment screw that is fixed on mouthful moulded board.
Compared with prior art, the utlity model has following beneficial effect:
The utility model mould is for the inhomogeneous particular design of two-layer tube wall thickness, and the equal capable of regulating of inside and outside wall can be guaranteed the uniformity of tube wall thickness.The utility model the mould features compact structure, simple to operate.The utility model mould can adapt to similar product forming mould to be used, and production stability is high, can effectively reduce the production percent defective.
Description of drawings
Fig. 1 is pipe material product figure;
Fig. 2 is the assembly drawing of die of the utility model hollow spiral hush pipe material;
Fig. 3 is the local enlarged diagram of the I of Fig. 2.
The specific embodiment
Below in conjunction with embodiment and accompanying drawing the utility model is described in detail.
Such as Fig. 2, shown in Figure 3, the mould of the open hollow spiral hush pipe material of the utility model, among the figure, comprise large mouthful moulded board 1 in the mould molding section, be enclosed within large mouthful of mould contraction cover 2, mouthful mould 4, be located at typing mouth mould 4 spacer shells 3, spacer shell holding screw 9, mouthful moulded board 5 on mouthful mould 4, be fixed on large mouthful of tight screw 10 of mold pressing and inwall adjustment screw 11 on the large mouthful of moulded board 1 and be fixed on mouth moulded board housing screw 7 and outer wall adjustment screw 8 on mouthful moulded board 5, be core rod 6 in the middle of the mould, the pipe material product 12 that mould is made, as shown in Figure 1.
Specifically such, plastic melt enters by extruder extruding and enters mould molding section → by observing profiled section mouth mould exit discharging situation after the compressed shunting of extrusion die → melt, the preliminary tubing inside and outside wall discharging uniformity → tubing of regulating is measured tubing wall thickness deflection → again regulate part accurate adjustment mould inside and outside wall discharging distribution by inside and outside wall behind cooling forming, guarantee that tubing is within control range.
Among Fig. 3, melt overlaps 2 parts through the contraction of mould, arrives a mouthful mould 4, core rod 6 moulding sections, and melt is through moulding section, by observing initial discharging situation in mouth mould 4 exits, by outer wall adjustment screw 8 and the inwall adjustment screw 11 preliminary discharging uniformities of regulating.
Measure the actual wall thickness deflection of tubing behind tubing 12 cooling formings, according to measuring the data obtained, again adjust inside and outside wall thickness by outer wall adjustment screw 8 and inwall adjustment screw 11, through 1-2 tiny adjustment, reach the production control requirement.
Above embodiment only is used for the explanation the technical solution of the utility model, is not intended to limit; Although with reference to preferred embodiment the utility model is had been described in detail; those of ordinary skill in the field are to be understood that; still can make amendment or the part technical characterictic is equal to replacement the specific embodiment of the present utility model; and not breaking away from the spirit of technical solutions of the utility model, it all should be encompassed in the middle of the technical scheme scope that the utility model asks for protection.
