Abstract

The utility model relates to a PVC section bar production field specifically is no steel lining PVC profile shapes mould. No steel lining PVC profile shapes mould includes mould main part, WPC crowded runner and PVC passageway altogether, the WPC whole straight line that is of crowded runner altogether link up the mould main part, is equipped with WPC feed inlet, core clearance lane, compression section, stable section and WPC feed runner in proper order, the PVC passageway includes PVC feed inlet, decompression angle, decompression runner, PVC feed runner, and PVC feed inlet and WPC be crowded runner mutually perpendicular altogether, and through the decompression angle, the decompression runner turns to and connect PVC feed runner, the export of PVC feed runner becomes more and more the level with the export of WPC feed runner.

Description

The mould of PVC profile without steel lining

Technical field

This utility model relates to PVC profile production field, specifically without steel lining PVC profile mould Tool.

Background technology

Plastic-steel door and window has become one of situation of selling well building materials, although people have appreciated that plastic-steel door and window Insulation, sound insulation, the aspect such as ageing-resistant be superior to the door and window of other materials.Joining of plastic-steel door and window Side is hard PVC polychloroethylene section bar, needs to add resin, interpolation during it manufactures Agent etc., owing to formula is different, can directly influence section bar uvioresistant, aging-resistant ability, And the intensity of section bar.It addition, no matter be window frame or sash, in four edges, generally add steel Lining, to strengthen the wind pressure resistant strength of door and window, the performance such as tension.PVC is most popular moulding One of material, PVC material is a kind of amorphism material, and in molecular resin chain, great majority are head-tails Head-the header structure of structure, only minority and tail-stern construction.The degree of polymerization of industrial PVC Between 500-2000.

In plastic-steel door and window, steel lining used all must reach certain thickness now, adds section bar Holistic cost and weight.The anticorrosion of steel lining, antirust treatment edge steel lining operation is cumbersome, adds Manufacturing time and cost.

Utility model content

This utility model aims to provide a kind of simple in construction for mould that PVC profile produces.

For overcoming the shortcoming of prior art, the technical scheme that this utility model provides is as follows:

The mould of PVC profile without steel lining, including die main body, WPC co-extruding flow channel and PVC passage, The described WPC the most through die main body of co-extruding flow channel entirety, be sequentially provided with WPC charging aperture, Shunting, core body gap, compression section, stable section and WPC feed runner；Described PVC passage includes PVC charging aperture, decompression angle, decompression runner, PVC feed runner, PVC charging aperture and WPC Co-extruding flow channel is mutually perpendicular to, and is turned to by decompression angle, decompression runner and is connected PVC feed runner, PVC feed runner exit and WPC feed runner exit tend to level.

Preferably, described PVC passage is divided into PVC integument runner and PVC profile molding Runner；Described PVC integument runner is distributed in top and the both sides of WPC feed runner；Described PVC profile molding runners is located at the bottom of WPC feed runner.

Preferably, described die main body mainly by die body, rebound, gripper shoe, cylinder manifold, Mouth template one, mouth template two, mouth template three stack gradually connection composition.

It is furthermore preferred that described die body, rebound, gripper shoe, cylinder manifold, mouth template one, mouth Screw is used to connect between template two, mouth template three.

This utility model has the advantages that

1, production mould simple in construction, production cost is low, is suitable for large application scope.

Accompanying drawing explanation

Fig. 1 is that this utility model is without steel lining PVC profile mold sections structural representation.

Fig. 2 is that this utility model is without steel lining PVC profile die face structural representation.

Detailed description of the invention

Below in conjunction with embodiment, this utility model content is described in further detail.

The mould of PVC profile without steel lining, as it is shown in figure 1, include die main body 1, WPC co-extrusion Runner 2 and PVC passage 3, the described WPC co-extruding flow channel 2 the most through die main body of entirety 1, it is sequentially provided with WPC charging aperture 21, shunting, core body gap 22, compression section 23, stable section 24 and WPC feed runners 25；Described PVC passage 3 includes PVC charging aperture 31, decompression angle 32, decompression runner 33, PVC feed runner 34, PVC charging aperture 31 and WPC co-extruding flow channel 2 are mutually perpendicular to, and are turned to by decompression angle 32, decompression runner 33 and are connected PVC feed runner 34, PVC feed runner 34 outlets tend to level with the outlet of WPC feed runner 25.Described mould Tool main body mainly by die body 4, rebound 5, gripper shoe 6, cylinder manifold 7, mouth template 1, Mouth template 29, mouth template 3 10 stack gradually connection composition.Described die body 4, rebound 5, Adopt between gripper shoe 6, cylinder manifold 7, mouth template 1, mouth template 29, mouth template 3 10 Connect with screw.

As in figure 2 it is shown, described PVC passage 3 is divided into PVC integument runner 341 and PVC Profile shapes molding runners 342；Described PVC integument runner 341 is distributed in WPC feed runner The top of 25 and both sides；Described PVC profile molding runners 342 is located at WPC feed streams The bottom in road 25.

Operation principle of the present utility model: WPC cycle stock is squeezed by two respectively with PVC material two Going out machine co-extrusion and enter WPC charging aperture and PVC charging aperture, WPC cycle stock is by die main body WPC co-extruding flow channel form core body, PVC material is respectively by the PVC profile in PVC passage Molding runners PVC molding outside to core with PVC integument runner and the cladding of PVC, formed Profile shapes.

It is obvious to a person skilled in the art that this utility model is not limited to above-mentioned exemplary reality Execute the details of example, and in the case of without departing substantially from spirit or essential attributes of the present utility model, This utility model can be realized in other specific forms.Therefore, no matter from the point of view of which point, Embodiment all should be regarded as exemplary, and be nonrestrictive, model of the present utility model Enclose and limited by claims rather than described above, it is intended that will fall in claim All changes in the implication of equivalency and scope are included in this utility model.Should will not weigh Any reference during profit requires is considered as limiting involved claim.
