Abstract
The utility model relates to a combined mould for hot-press plastic tube materials, particularly the mould of the tube materials for producing the ultrahigh molecular weight polyethylene or the composite ultrahigh molecular weight polyethylene. The combined mould for hot-press plastic tube materials comprises a base, an upper cover plate, and a tubular internal mould; the tubular internal mould is spliced by three to seven mould plates and three to seven plugging strips. The both ends of the mould plates and the plugging strips are respectively provided with connecting pieces, and the mould plates and the plugging strips are clamped and fixed through screws. The combined mould for hot-press plastic tube materials is suitable for the tube materials of the ultrahigh molecular weight polyethylene which are formed by the hot press and is also suitable for other plastic manufacturing tube materials. The combined mould for hot-press plastic tube materials has the advantages of simple structure, easy manufacturing, and convenient operation.
Description
The utility model relates to a kind of assembling die that is used for hot-pressing plastic tubing, particularly produces the mould of ultra-high molecular weight polyethylene or compound ultrahigh molecular weight polyethylene tubing.
Use thermoforming process to produce plastic pipe at present, adopt extrusion molding or injection mo(u)lding mostly, also have employing hot-forming.Make plastic pipe for using hot-press molding method, because mould and plastic hot expansion coefficient difference, make the demoulding that difficulty take place, particularly for producing ultra-high molecular weight polyethylene or compound ultrahigh molecular weight polyethylene tubing, the demoulding does not solve so far, its key is that mould structure is unreasonable, particularly internal model structure.
The purpose of this utility model provides a kind of novel die of producing plastic pipe, and it and existing mold difference are that the tubulose internal mold has 3～7 templates, insert tent between the adjacent forms, form the removable tubular internal mold.
Below in conjunction with embodiment and accompanying drawing the utility model is described.
Fig. 1 the utility model structural representation.
Fig. 2 tent structure chart
Referring to accompanying drawing, the utility model is an assembling die, is the improvement of producing on the pipe mold basis existing.The mould of existing hot-forming manufacturing plastic pipe comprises base (1), upper cover plate (2) and tubulose internal mold, the edge laterally has half-cylindrical cavity (4) on the chassis, the edge laterally also has half-cylindrical cavity (4) on the upper cover plate, both screw connection with bolt by fastening, and cavity shape is cylindrical.The tubulose internal mold is placed on wherein, and plastic grain is added in base, loam cake and internal mold space, sends into hot press again, makes plastic pipe through heating, hot pressing, the demoulding.The utility model changes the tubulose internal mold by 3～7 templates (5) and 3～7 tents (6) into is put together, and template and tent are fixedly clamped by brace (7).In order to narrate conveniently, base and upper cover plate are generically and collectively referred to as external mold.Be provided with steel ring between internal mold and the external mold, steel ring diameter and width and the pipe diameter of being produced, wall thickness are identical.
The utility model is a kind of assembling die that is used for hot-pressing plastic tubing, comprise external mold and the tubulose internal mold formed by base (1) and upper cover plate (2), comprise external mold and the tubulose internal mold formed by base (1) and upper cover plate (2), it is characterized in that the tubulose internal mold is put together by 3～7 templates (5) and 3～7 tents (6), template and tent two ends respectively are provided with brace (7) and by screw (8) template and tent are fixedly clamped.
Referring to Fig. 1, template is the metallic plate that is the circular arc cylinder.
Referring to Fig. 2, tent is a middle bonding jumper that is provided with high platform (3), and it is high identical with brace thickness, and the tent two ends are thick identical with template thickness.
When using the assembling die demoulding of the present utility model, axially remove a tent along plastic tube, the tubulose internal mold of being made up of a plurality of templates can be easy to and hot-forming plastic pipe is thrown off.
Cavity shape described in the utility model and size can make up according to actual needs, and the length of its goods diameter, pipe can be formed series of products from big to small.
Assembling die of the present utility model is not only applicable to use hot-forming ultrahigh molecular weight polyethylene tubing, is applicable to other plastics manufacturing tubing yet.This assembling die processing simple in structure, easy, easy to use.
