Description
Technical field
The present invention relates to a kind of for the production of MULTILAYER COMPOSITE extrusion moulding equipment, be specially multi-layer composite mold extrusion die.
Background technology
At present, existing multilayer extrusion die head product is out generally by distributor compound, and this scheme is only applicable to the close raw material (± 10 °) of fusing point, if between raw material, melting temperature is greater than (± 10 °), this scheme just cannot reach requirement, as shown in Figure 1.Now, the transmission being intercepted temperature between different material by thermal insulation hole is needed between three charging apertures.Due to inner skeleton limited space, the distance between each runner is too near, and the effect that thermal insulation hole is played is unsatisfactory.
Summary of the invention
The object of the present invention is to provide heat insulation type Multilayer composite extrusion die head, while multilayer raw material compound, the temperature of its each layer can be controlled separately again.
Above-mentioned purpose is achieved through the following technical solutions:
Heat insulation type Multilayer composite extrusion die head, it is characterized in that: include upper die and lower die body, upper front mould and lower front mould, wherein go up the front end that front mould is arranged on patrix, lower front mould is arranged on the front end of counterdie, upper die and lower die form first flow, first flow, together with the first charging aperture, ensures technique for producing raw material temperature by the heating rod arranged on patrix; Patrix and upper front mould form the second runner, and the second runner, together with the second charging aperture, ensures technique for producing raw material temperature by being provided with heating rod at upper front mould; Counterdie and lower front mould form the 3rd runner, and the 3rd flow passage the 3rd charging aperture, ensures technique for producing raw material temperature by being provided with heating rod at lower front mould; Upper front mould and lower front mould form compound runner, and compound runner connects first flow, the second runner, the 3rd runner; At first flow and the second runner, be respectively equipped with thermal insulation hole between first flow and the 3rd runner to intercept the transmission of temperature.
Further, described thermal insulation hole is double setting, and the thermal insulation hole between first flow and the second runner is arranged on patrix, and the thermal insulation hole between first flow and the 3rd runner is located at counterdie.
Further, described compound runner is at the discharging joint of first flow, the second runner and the 3rd runner and first flow, the second runner, the 3rd flow passage.
Further, described heating rod is separately positioned on upper die and lower die, upper front mould and lower front mould.
Further, described insulation hole is long deep hole, and the aperture of each insulation hole is in communication with the outside.
Further, described insulation hole is oil/water circulation port, and insulation hole inner passage is interconnected and forms cool cycles oil/water road.
Adopt the heat insulation type Multilayer composite extrusion die head of said structure, die body is provided with three charging apertures, form three road runners, and the structure in thermal insulation hole between each runner, while multilayer raw material compound can be made, avoid the technological temperature between each raw material to influence each other, thus destroy the characteristic of raw material, make produced product reach requirement, structure of the present invention is simple, is easy to realize.

Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described.
As in Figure 2-4, heat insulation type Multilayer composite extrusion die head, include patrix 1, counterdie 2, upper front mould 3 and lower front mould 4, wherein go up the front end that front mould 3 is arranged on patrix 1, lower front mould 4 is arranged on the front end of counterdie 2, patrix 1 and counterdie 2 form first flow 10, and first flow 10, together with the first charging aperture a, ensures technique for producing raw material temperature by the heating rod 17 arranged on patrix 1; Patrix 1 and upper front mould 3 form the second runner 20, second runner 20 together with the second charging aperture b, ensure technique for producing raw material temperature by being provided with heating rod 18 at upper front mould 3; Counterdie 2 and lower front mould 4 form the 3rd runner the 30, three runner 30 and are communicated with the 3rd charging aperture c, ensure technique for producing raw material temperature by being provided with heating rod 19 at lower front mould 4; Upper front mould 3 and lower front mould 4 form compound runner 40, and compound runner 40 connects first flow 10, second runner 20, the 3rd runner 30; At first flow 10 and the second runner 20, be respectively equipped with thermal insulation hole 11,12 between first flow 10 and the 3rd runner 30 to intercept the transmission of temperature.
As Figure 2-3, thermal insulation hole 11,12 is double setting, and the thermal insulation hole 11 between first flow 10 and the second runner 20 is arranged on patrix 1, and the thermal insulation hole 12 between first flow 10 and the 3rd runner 30 is located at counterdie 2.First flow 10 and the second runner 20 are by thermal insulation hole 11 thermal insulation, and first flow 10 and the 3rd runner 30 are by thermal insulation hole 12 thermal insulation.In the present embodiment, insulation hole 11,12 is long deep hole, and the aperture of each insulation hole is in communication with the outside.When in order to improve effect of heat insulation, can be designed to oil/water circulation port by insulation hole, insulation hole inner passage is interconnected and forms cool cycles oil/water road.
As shown in Figure 2, compound runner 40 is communicated with first flow 10, second runner 20, the 3rd runner 30 with the discharging joint 14,15,16 of the 3rd runner 30 at first flow 10, second runner 20.After raw material enters respective runner from charging aperture a, b, c, then discharging enters compound runner 40 again and carries out compound, then extrudes from final discharging opening 50 production that raw material that compound is good carries out product.
Thermal insulation hole 11,12 of the present invention be arranged so that heat insulation type Multilayer composite extrusion die head directly can carry out compound in same die head, even if the temperature difference of different material technological temperature reaches 50 degree can well intercept temperature transmission, thus makes raw material keep original characteristic thus reach the requirement of production.Structure of the present invention is simple, is easy to realize.
