Abstract
The invention discloses an assembling mould of a shock-isolation rubber bearing, belonging to the technical field of manufacturing and designing of a rubber product mould. The assembling mould comprises a lower mould base, a hoisting plate, a lower flange plate and a lower pressure mould ring, a middle mould, an upper flange plate and an upper pressure mould ring from top to bottom in sequence after being assembled, wherein the upper end surface of the lower mould base and the lower end surface of the upper mould base are respectively provided with fixing slots of the lower pressure mould ring and the upper pressure mould ring; heat conduction rods which are uniformly distributed are vertically upwards fastened on the hoisting plate; a mandrel is vertically upwards fastened in the middle of the hoisting plate; the middle mould is formed by the enclosing of four same joining blocks; the two end surfaces of each jointing block are ladder-shaped; the ladder-shaped end surfaces of adjacent two joining blocks can be engaged; and a heat conduction oil cavity for the feeding of hot oil is formed in the middle mould. The assembling mould provided by the invention is convenient to pre-assemble; the auxiliary oil-bath heating is adopted by the middle mould, so that not only can operating personnel make overall arrangements for the assembling time, but also heat in the vulcanizing process is uniformly transmitted. The film has good vulcanizing uniformity, the vulcanizing time of the shock-isolation rubber bearing can be shortened, and the production efficiency is improved.
Description
Technical field [0001] The invention belongs to the technical field of design and manufacture of rubber product molds, and in particular relates to a mold for vulcanizing a shock-isolating rubber support. Background technique [0002] The vibration isolation rubber bearing is a thick building product made of rubber and steel plate. Rubber is a poor conductor of heat. As the thickness of the product increases, the temperature difference between the inner and outer layers of the product increases during the vulcanization process. Therefore, the vulcanization effects of the inner and outer layers obtained within the same vulcanization time are not equal, resulting in a difference in vulcanization uniformity. The higher the curing temperature, the greater the difference, so thick products must be cured at a relatively low temperature for a longer time. [0003] Pre-heating the frame plate, film, and sealing plate of the shock-isolating rubber support can improve the uniformity of the ...
