Abstract
An extrusion mould-head for producing plastic pipes with sound-insulated holes of the utility model is provided with a porous plate, a mould head body, a diffluence body, a core mould, a neck mould, a gland bush, a core base, and sound insulated hole pipe type cores. The core base is arranged on the lower end of the core mould, and the core base and the core mould are installed on the diffluence body. A material feed path is formed between the core base and inner holes of the neck mould, and the material feed path positioned on the core mould part is a conical material feed path and a pipe wall mould cavity. The sound insulated hole pipe type cores are arranged along the circumference of the pipe wall mould cavity, are inserted in a core hole arranged on the core base through the core hole arranged on the taper part of the core mould, and then are fixed on the core base. Sectional materials extruded from the pipe wall mould cavity are turned to sound-insulated plastic pipes through shaping and cooling.
Description
The utility model relates to a kind of extrusion die that is used to make the plastic pipe with sound insulation hole pipe.
Axial direction along pipe in the tube wall of plastic pipe is provided with the penetrating sound insulation hole pipe in two ends, and sound insulation hole pipe is laid along the circumferencial direction of tube wall promptly becomes the plastic pipe with deadening, obviously, with known be used for making plastic pipe to make this plastic pipe with sound insulation hole pipe by porous plate, die head body, the extrusion die that divides fluid, core, mouthful mould and gland to assemble be not all right.
The purpose of this utility model provides a kind of extrusion die that is used to make the plastic pipe with sound insulation hole pipe.
Solution of the present utility model is the improvement design to the plastic pipe extrusion die, the lower end that is described core is provided with the fuse seat, and be installed in together on the branch fluid with core, fuse seat and core are with forming the defeated material road that connects with the defeated material road that divides on the fluid between the endoporus of mouthful mould, and the defeated material road that is positioned at the core position is taper material road and tube wall die cavity, along the circumferential direction lay sound insulation hole cast core in the tube wall die cavity, this sound insulation hole cast core passes to insert behind the cored hole of the cone portion that is located at core and is located at the cored hole of fuse seat and is fixed on the fuse seat.
The essence of above-mentioned technical solution is by to the improvement of core and mouthful mould and make the sound insulation hole cast core that forms sound insulation hole pipe can pass core after setting up the fuse seat to obtain the location at the fuse seat, like this, can make the section bar of from the tube wall die cavity, extruding after Vacuum shaping and cooling, become plastic pipe with sound insulation hole pipe.
Illustrate particular content of the present utility model below in conjunction with drawings and Examples.
Fig. 1: structure chart of the present utility model;
Fig. 2: A-A cutaway view.
As shown in the figure, the extrusion die that is used to make the plastic pipe with sound insulation hole pipe described in the utility model also has porous plate 1, die head body 2, divide fluid 3, core 4, mouth mould 5 and gland 6, wherein the die head body 2, divide fluid 3 and gland 6 to be bolted together by screw 7, the inward flange 8 that is located at simultaneously on the gland 6 fastens and mouth mould 5 is bearing on the end face of branch fluid 3 with the outward flange 9 that is located on mouthful mould 5, pass of the periphery contact of gland 6 backs along the adjustment screw 10 that radially is provided with of gland 6 with the outward flange 9 of mouthful mould 5, be provided with between the cone-shaped wall 14 of cone portion 11 with the die head body 2 that is provided with tapered hole and material road import 13 of branch fluid 3 in cone portion 11 and defeated material road 12 and form taper material road 15,1 of porous plate is inlaid in material road import 13 places of die head body 2, the utility model is provided with fuse seat 16 in the lower end of core 4, and be installed in together on the branch fluid 3 with core 4, fuse seat 16 and core 4 are with forming the defeated material road 17 that connects with the defeated material road 12 that divides fluid 3 between the endoporus of mouthful mould 5, and the defeated material road 17 that is positioned at core 4 positions is taper material road 18 and tube wall die cavity 19, along the circumferential direction lay sound insulation hole cast core 20 in the tube wall die cavity 19, this sound insulation hole cast core 20 passes to insert behind the cored hole of the cone portion 21 that is located at core 4 and is located at the cored hole of fuse seat 16 and is fixed on the fuse seat 16.In addition, it is tight that core 4 and the mounting means of fuse seat 16 on minute fluid 3 generally adopt screw 22 to piece together, and screw 22 screws in the screwed hole that is located at branch fluid 3 centers after normally passing the bolt hole that is located at core 4 and fuse seat 16 centers.Die head body 2 is extrusion die connectors with extruder, so die head body 2 is provided with connecting thread 23, and the quantity of adjustment screw 10 generally is four, is distributed on the platen 6, and its effect is the position of adjusting mouthful mould 5, makes the pipe thickness unanimity.
