The specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is elaborated.
As Fig. 1-shown in Figure 3; rubber diaphragm of automobile brake chamber circulation shaped device of the present invention comprises a vacuum vulcanization press 1; two injection vulcanizing press 2; mould emptier 3; diaphragm of rubber curing forming mold and injection vulcanizing press 100; the diaphragm of rubber curing forming mold is the multiple mode structure that includes quadruplet curing forming mold unit; comprise lower bolster 107; middle template 106; first cope match-plate pattern; second cope match-plate pattern 105, counterdie 109; pressure ring 110; once sulfuration is separately positioned on lower bolster 107 with patrix and post-cure with patrix 108; middle template 106; on first cope match-plate pattern and second cope match-plate pattern 105.
The form that is provided with of runner 114 has multiple, can also adopt another kind of form, runner plate is by upper stream guidance tape 101, middle level runner plate 101 ' and underflow guidance tape 102 fit tightly from top to bottom and form, glue feeding opening 115 is arranged on upper stream guidance tape 101 upper surfaces, plastic hole 113 is arranged on underflow guidance tape 102 lower surfaces, be provided with flow path groove at middle level runner plate 101 ' upper surface and underflow guidance tape 102 upper surfaces, up/down perforation is set on the middle level runner plate 101 ' is used for connecting the connecting hole that is positioned at the flow path groove on middle level runner plate 101 ' and the underflow guidance tape 102, flow path groove is at upper stream guidance tape 101, middle level runner plate 101 ' and underflow guidance tape 102 fit tightly down and form runner 104.
The axis of hole for injecting glue 112 parallels with the axis of post-cure with patrix 108, and hole for injecting glue 112 subtracts big bellmouth from the top down gradually for radial dimension.This mode is convenient to the vulcanized rubber in the hole for injecting glue is cleared up, and operating personnel can extract the residual sizing material in the hole for injecting glue 112 very easily.
The axis of plastic hole 113 parallels with the axis of post-cure with patrix 108, and the bellmouth that reduces gradually from the top down for radial dimension of plastic hole 113.Plastic hole 113 is a sizing material passage inside radius minimum with the junction of hole for injecting glue 112, and during the residual sizing material in removing hole for injecting glue 112, the sizing material in the hole for injecting glue 112 is easy fracture more like this.
When if the heat-insulating capability of thermal insulation board 103 can't satisfy, can adopt the mode of circulation cold oil to make the runner plate cooling.
As Fig. 4, shown in Figure 5, for the diaphragm of rubber curing forming mold is the single mode structure that only includes 1 cover curing forming mold unit, the single mode structure is with the difference of multiple mode structure, die unit quantity difference, runner plate also can be from multiple mode structure three, reduce to two in the single mode structure, certainly, the form of runner plate only is not limited to this.
Runner plate divides the body structure except adopting, can also adopt and on the bulk flow guidance tape, utilize drill bit to offer the mode of runner,, can form the runner plate internal structure equally so at last with unnecessary borehole sealing, but divide body structure comparatively time-consuming relatively, also be unfavorable for the cleaning of runner plate inner flow passage.
Referring to Fig. 1, on the sealing moving loop of working plate 5, have four transfer bogiies 4, the quantity of certain also dolly can reduce also and can increase according to the cure time of guide rail 7 length and every press, the following describes its operation process:
1) dolly 4 that is arranged in place, vacuum vulcanization press 1 input port utilizes its driving mechanism that the working plate on the dolly 45 is outputed to vacuum vulcanization press 1;
2) sizing material and the canvas in 1 pair of working plate 5 mold of vacuum vulcanization press carries out vulcanizing treatment one time, and after processing finished, vacuum vulcanization press 1 utilized self driving mechanism working plate 5 to be outputed on the dolly 4 that is positioned at vacuum vulcanization press equipped at outlet port;
3) dolly 4 is transported to working plate 5 on the wherein platform of two injection vulcanizing press 2, be sent to the processing progress which platform injection vulcanizing press 2 depends on three injection vulcanizing press 2, be sent to processing progress that injection vulcanizing press 2 faster, this logic is judged can be by artificial or programme-control;
4) the injection vulcanizing press 100 pair working plates 5 mold injecting glues of injection on the vulcanizing press 2, and carry out post-cure and handle output to working plate 5 on the dolly 4 that is positioned at its equipped at outlet port by self driving mechanism after finishing;
5) dolly 4 carries working plate 5 and moves to mould emptier 3, after moving into place, by self driving mechanism working plate 5 is outputed on the mould emptier 3;
6) mould emptier 3 utilizes wherein the template lifting device that middle template is promoted to break away from lower bolster, take out the diaphragm of rubber finished product by operating personnel, and after in counterdie, putting into a new vulcanized rubber and canvas, middle template relay get back on the lower bolster, finally demould mechanism 3 outputs to working plate 5 on the dolly 4 that is positioned at its equipped at outlet port by self driving mechanism;
7) dolly 4 carries working plate 5 to place, vacuum vulcanization press 1 input port, waits for the beginning of next diaphragm of rubber process-cycle.
Above-mentioned example is used to just illustrate that the present invention, embodiments of the present invention are not limited to these examples, and the various specific embodiment that meet inventive concept that those skilled in the art made are all within protection scope of the present invention.
