Rail transit rubber anti-vibration pad mold with anti-displacement and anti-sliding functions

Abstract

The invention provides a rail transit rubber anti-vibration pad mold with anti-displacement and anti-sliding functions. The rail transit rubber anti-vibration pad mold with the anti-displacement and anti-sliding functions comprises a vulcanizing press upper flat plate, a hot press forming mold and a vulcanizing press lower flat plate which are arranged from top to bottom; the hot press forming mold comprises an upper mold plate, a middle mold plate and a lower mold plate which are combined together from top to bottom; the upper mold plate is fixedly mounted on the lower surface of the vulcanizing press upper flat plate, and the lower mold plate is fixedly mounted on the upper surface of the vulcanizing press lower flat plate; and the lower surface of the upper mold plate is fixedly provided with an upper air leakage structure, the upper surface of the lower mold plate is fixedly provided with a lower air leakage structure, and the middle mold plate is fixed to the lower surface of the upper air leakage structure. The surface of the upper air bleeding structure and the surface of the lower air bleeding structure are respectively provided with through vent holes.

Description

technical field [0001] The invention relates to the technical field of hot-pressing molds, in particular to a rubber damping pad mold for rail transit with anti-displacement and sliding functions. Background technique [0002] With the development of society and the advancement of science and technology, major cities are paying more and more attention to the development of urban rail transit. The construction of urban rail transit, especially underground railways, has been greatly expanded. The vibration and noise generated when rail vehicles run quickly have a great impact on the running track bed and rail transit. If the upper part and surrounding properties and residents have great damage and impact, it is necessary to have technical products that can reduce vibration and noise to ensure the safety of line operation and surrounding properties. The rubber vibration damping pad can meet the requirements of railway vibration isolation and noise reduction, and this product ha...

Problems solved by technology

The other is to add cloth between the upper and lower plates of the vulcanization press to form two gas diversion layers, which is more effective. Using the cloth as a gas diversion layer must use transmission components before and after the vulcanization press , that is, the padding is opened and the padding is taken up, which increases the purchase cost of the equipment, increases the length of personnel and production equipment, and correspondingly expands the production site. At the same time, the padding will age after a certain period of use, and must be replacement, which increases the total cost of the product accordingly
