The present invention also provides the production method of the above-mentioned mould of utilization, and it may further comprise the steps:
1), in the die cavity of counterdie upper surface, put into working of plastics to be processed, make the upper die and lower die matched moulds then, the passage of the injection elastomeric material in the patrix is in closed condition;
2), to upper die and lower die heating, the vacuum-pumping pipeline through counterdie vacuumizes simultaneously;
3), reach design temperature when upper die and lower die, the vacuum-pumping pipeline of counterdie is injected elastomeric material through being provided with the passage that injects elastomeric material in the patrix after reaching the vacuum of setting simultaneously;
4), vulcanize for the elastomeric material that injects;
5), after sulfuration reaches setting-up time, open patrix, take out manufactured goods, get into next circulation;
Its key point is: the process of injecting elastomeric material and sulfuration is carried out under vacuum state.
Preferably the vacuum in vacuum-pumping pipeline described in the process of injecting elastomeric material and sulfuration is set at 0.03MPa～0.04MPa.
The design temperature of preferred said upper die and lower die is 175 ℃～185 ℃.
Preferred described cure time is 7.5 minutes～8.5 minutes.
The present invention is provided with the vacuum-pumping pipeline that is communicated to outside vaccum-pumping equipment because the periphery of said die cavity is provided with the sealing ring that seals mutually with the patrix lower surface in the counterdie upper surface in the space that said counterdie upper surface sealing ring surrounds, and on structure, just guarantees like this injecting elastomeric material and need not carry out exhaust to the production process that elastomeric material vulcanizes; The process of injecting elastomeric material and sulfuration is carried out under vacuum state; Thereby shorten the time of producing, the time of sulfuration is also shortened greatly, enhance productivity; Again owing to need not frequent exhaust; Just can better protect mould, reduce the loss of mould, and then improve yield of products.

The specific embodiment
Below in conjunction with accompanying drawing and concrete embodiment the present invention is done further explain.
Fig. 1 is to shown in Figure 6; A kind of mould that is used for adhesive rubber layer on working of plastics; Comprise patrix 1, counterdie 2, counterdie 2 upper surfaces are provided with three and the corresponding die cavity 21 of working of plastics profile to be processed, and the lower surface of patrix 1 is provided with and counterdie 2 upper surface die cavities 21 corresponding three die cavities 11; The periphery of the said die cavity 21 in counterdie 2 upper surfaces is provided with a circle groove 22; Sealing ring 3 is housed on the groove 22, and patrix 1 lower surface also is provided with a circle and said sealing ring 3 corresponding grooves 12, and described sealing ring 3 makes said sealing ring 3 surround when patrix 1 and counterdie 2 are pressed together space forms sealing with the outside; Said counterdie 2 upper surfaces are arranged in the space that the sealing ring 3 in the groove 22 surrounds and are provided with the vacuum-pumping pipeline 23 that is communicated to outside vaccum-pumping equipment, and this vacuum-pumping pipeline 23 can be made up of pipeline 231 that is arranged on counterdie 2 sides and a plurality of through holes 232 that are communicated between the said die cavity 21 of counterdie and said die cavity 21 and the sealing ring 3;
