Description
Technical field
The utility model relates to a kind of extrusion molding machine head mould.
Background technology
Extrusion molding is generally used for the production of the contact such as tubing, bar, sheet material, film, the wire rod section bar of thermoplastic, the plastic obtained has stable cross sectional shape, and extrusion molding is a kind of of many uses, a kind of process that proportion is very large in thermoplastic plastics shaping.In extrusion molding process, homogenous plasticized plastic melt moves to barrel leading portion along with the rotation of screw rod, screw rod rotary squeezing effect once, the section bar consistent with Oral incision is obtained by the mouth mould of definite shape, temperature is one of important parameter in this process, and the fluctuation of its temperature all can affect the quality of plastic, makes plastic produce residual stress, each point intensity is uneven, and surface ash is dim unglazed.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of plastic melt homogeneous temperature, circulation a kind of extrusion molding machine head mould smoothly.
In order to solve the problems of the technologies described above, the technical solution of the utility model is:
A kind of extrusion molding machine head mould, comprise cope match-plate pattern and lower bolster, combine between wherein said cope match-plate pattern and described lower bolster and form stream road, described stream road is shunted in tree successively at many levels along charging aperture to discharging opening direction, described material runner inner wall covers and is linked with Electric radiant Heating Film, and described Electric radiant Heating Film is provided with inner insulating layer from inside to outside successively, thick film circuit layer and external insulation layer, also be provided with a thermocouple in described stream road, described stream road charging aperture is provided with a pressure sensor.
Preferably, above-mentioned a kind of extrusion molding machine head mould, wherein said thick film circuit layer comprises thick film circuit, and this thick film circuit is made up of the heater circuit that multichannel is parallel with one another, and it is also electrically connected with a step switch.
Preferably, above-mentioned a kind of extrusion molding machine head mould, wherein said stream road becomes two strands by one along charging aperture successively to discharging opening direction, then becomes four strands by two strands, then becomes stereotyped writing by four strands, and stereotyped writing becomes 16 strands.
Preferably, above-mentioned a kind of extrusion molding machine head mould, tributary runner size, the shape of wherein said stream road every one deck bifurcation are corresponding.
Preferably, above-mentioned a kind of extrusion molding machine head mould, wherein said cope match-plate pattern is also connected with a die lip adjustment screw corresponding with die lip position and adjustment screw.
Compared with prior art, the utility model technique effect is mainly reflected in: in the utility model, stream road is shunted in tree successively at many levels along charging aperture to discharging opening direction, this branched stream runner form, easy guarantee whole die orifice discharging uniformity, and on, the part of Gong the arrangement joint bolt of lower bolster is more, even if pressure height is not yielding yet, expect that runner inner wall covers simultaneously and be linked with Electric radiant Heating Film, it effectively can alleviate long flow path, the problem that resistance is large, ensure that the plastic melt homogeneous temperature of circulation in stream road is consistent, there is overburden phenomenon for preventing during low temperature simultaneously, in stream road, charging aperture place should arrange pressure sensor.
In addition, die lip carrys out the sheet material of production plurality of specifications and different-thickness by adjustment screw, then can be finely tuned the thickness uniformity of local discharging by die lip adjustment screw.
Accompanying drawing explanation
Fig. 1: the utility model structure side view;
Fig. 2: the utility model structure sectional view.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail, is easier to make technical solutions of the utility model understand and grasp.
As shown in Fig. 1 ~ Fig. 2, a kind of extrusion molding machine head mould, comprise cope match-plate pattern 1 and lower bolster 2, combine between wherein said cope match-plate pattern 1 and described lower bolster 2 and form stream road 3, described stream road 3 is shunted in tree successively at many levels along charging aperture to discharging opening direction, described stream road 3 inwall covers and is linked with Electric radiant Heating Film, described Electric radiant Heating Film is provided with inner insulating layer from inside to outside successively, thick film circuit layer and external insulation layer, also be provided with a thermocouple 7 in described stream road, described stream road 3 charging aperture is provided with a pressure sensor 6.
Wherein, described thick film circuit layer comprises thick film circuit, and this thick film circuit is made up of the heater circuit that multichannel is parallel with one another, and it is also electrically connected with a step switch.
As shown in Figure 2, described stream, 3 become two strands by one along charging aperture successively to discharging opening direction, then become four strands by two strands, then become stereotyped writing by four strands, and stereotyped writing becomes 16 strands.
Tributary runner size, the shape of the every one deck bifurcation in described stream road 3 are corresponding.
Described cope match-plate pattern 1 is also connected with a die lip adjustment screw 9 corresponding with die lip 5 position and adjustment screw 8.
In this technical scheme, stream road is shunted in tree successively at many levels along charging aperture to discharging opening direction, this branched stream runner form, easy guarantee whole die orifice discharging uniformity, and on, the part of Gong the arrangement joint bolt of lower bolster is more, even if pressure height is not yielding yet, expect that runner inner wall covers simultaneously and be linked with Electric radiant Heating Film, it effectively can alleviate long flow path, the problem that resistance is large, ensure that the plastic melt homogeneous temperature of circulation in stream road is consistent, there is overburden phenomenon for preventing during low temperature simultaneously, in stream road, charging aperture place should arrange pressure sensor.
In addition, die lip carrys out the sheet material of production plurality of specifications and different-thickness by adjustment screw, then can be finely tuned the thickness uniformity of local discharging by die lip adjustment screw.
Certainly, be more than representative instance of the present utility model, in addition, the utility model can also have other multiple detailed description of the invention, and all employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop within the claimed scope of the utility model.
