Abstract
The invention relates to a method for the hot vulcanization of rubber part products, in particular to a method and equipment for rubber vulcanization. The method comprises: firstly, winding a little amount of mixed rubber on a workpiece; secondly, placing the workpiece in a cavity of a lower mold of a mold; thirdly, closing an upper mold and the lower mold, placing a feeding tank at the position of a rubber pouring opening of the upper mold, and placing a certain amount of mixed rubber in a tank body; fourthly, placing a core body of the feeding tank into the feeding tank and screwing an exhaust nozzle; fifthly, placing the mold in a vulcanizing machine and slowing pressurizing the mold; and finally, after the exhaust nozzle spray rubber, closing an exhaust valve, continuing to pressurize the mold for 5 to 10 seconds (determined according to the size of the workpiece), stopping the pressurization, and keeping the pressure till the end of the vulcanization time. The method and the equipment are suitable for the vulcanization of rubber parts with or without cables. The method and the equipment have the advantages that: the internal structures of the rubber parts are compact, firm and free from bubbles; and the surfaces of the rubber parts are smooth and free from rubber shortage.
Description
Technical field
The present invention relates to a kind of method of rubber part products hot vulcanization process.Be a kind of method of tape cable rubber part products hot vulcanization process specifically.
Background technology
General sulfuration is that the sizing material that mixes is directly put into mold cavity, and matched moulds is put into vulcanizer and carried out heat cure, or with the workpiece encapsulate, puts into the die cavity matched moulds then and puts into vulcanizer and carry out heat cure.Specific practice is: before the rubber sulfuration, need heating and cleaning mold cavity, the spraying releasing agent.Put into mold cavity to the rubber that mixes then, if the goods of tape cable then need twine glue earlier, the volume that twines glue is greater than mold cavity volume, puts into die cavity to workpiece then, and matched moulds is also put into vulcanizer and carried out heat cure.Above-mentioned situation is mobile the increase in rubber heating back.Die cavity is full of back rubber to be continued outwards to flow along flash groove, and interior pressure will reduce like this, cause a certain amount of bubble, produce the starved phenomenon.The sketch map of the rubber parts of producing for prior art shown in Figure 2 produces bubble 12 in the workpiece 11.
Summary of the invention
For solving the problems of the technologies described above, the purpose of this invention is to provide the equipment of method and realization the inventive method of a kind of rubber part products hot vulcanization process, concrete scheme is:
A kind of vulcanization of rubber method comprises the steps:
(1). the film that mixes is twined on workpiece, and volume is less than mold cavity;
(2). the workpiece that winds is put into the counterdie of mould;
(3). upper mould and counterdie are lumped together;
(4). place feed pot at patrix injection port place;
(5). a certain amount of elastomeric compound is put into feed pot;
(6). the feed pot core body is put into feed pot;
(7). exhaust nozzle is screwed on the exhaust outlet of patrix, opens drain tap;
(8). mould is put in the middle of the vulcanizing press;
(9). slowly the adhesive tape of discharging in the exhaust nozzle is observed in pressurization;
(10). close the exhaust nozzle valve;
(11). continue slowly to pressurize for 5～10 seconds.(deciding) according to the workpiece size.
(12). stop pressurization, carry out pressurize by the vulcanized rubber curing time.
The invention also discloses a kind of equipment of realizing said method, comprise upper die and lower die; Patrix is provided with injection port, on the said injection port feed pot is set, and is provided with core body in the said feed pot; Said patrix is provided with exhaust outlet, and said exhaust outlet is provided with drain tap.
Be the rubber of processing belt cable, said upper and lower mould also is provided with folder cable cover.
For processing has the rubber of workpiece and cable, said upper and lower mould also is provided with workpiece cavity.
The invention of this technology has following advantage:
1. need not purchase glue-injection machine equipment, just can reach the effect of injecting glue.Therefrom saved the spending of purchasing injecting glue equipment;
2. be fit to the production of small lot and accurate rubber;
3. be fit to the production of tape cable rubber;
4. it is high to vulcanize the product strength that, and internal structure density is good, surface no starved phenomenon and smooth;
5. use the product percent of pass of this explained hereafter high;
6. range of application is wider, is fit to tape cable goods and the not production of tape cable goods;
7. sizing material is saved in this technology invention in sulfidation, reduces the cost of product.
Description of drawings
Fig. 1 is the present device structure diagram;
Fig. 2 is the prior art constructions sketch.
The specific embodiment
Below in conjunction with description of drawings the present invention, as shown in Figure 1, equipment of the present invention comprises patrix 210, counterdie 213; Patrix is provided with injection port 28, and said injection port 28 is provided with feed pot 26, is provided with core body 25 in the feed pot 26; Said patrix 210 is provided with exhaust nozzle 23, and said exhaust nozzle 23 is provided with drain tap 21;
Patrix 210, counterdie 213 also are provided with folder cable cover 211 and are used for clamping cable 212;
Patrix 210, counterdie 213 also are provided with workpiece 24 die cavities.
Method for using of the present invention is:
(1). the film that mixes is twined on workpiece 24, and volume is less than mold cavity;
(2). the workpiece that winds is put into the counterdie 213 of mould;
(3). upper mould 210 and counterdie 213 are lumped together;
(4). place feed pot 26 at patrix 210 injection ports 28 places;
(5). a certain amount of elastomeric compound 27 is put into feed pot 26;
(6). feed pot core body 25 is put into feed pot 26;
(7). exhaust nozzle 23 is screwed on the exhaust outlet of patrix 210, opens exhaust nozzle valve 21;
