METHOD FOR MANUFACTURING OF MECHANICAL RUBBER GOODS AND DEVICE FOR ITS REALISATION Russian patent published in 2009 - IPC B29D22/00 B29C35/04 

FIELD: technological processes.

SUBSTANCE: invention is related to production of mechanical rubber goods. Method for production of mechanical rubber goods consists in installation of die mold in vertical vulcanising boiler, product billet installation in it with further moulding, supply of heat for die mold heating. As heating temperature becomes less than vulcanisation temperature by 30-35°C in one of parts of die mold fixed by sensor, electric heating elements controlled by this sensor are disconnected from heat supply. After the same temperature is achieved in another part of die mold, appropriate sensor disconnects electric heating elements of cylindrical part. After heating to the same temperature of the last part of die mold, vulcanisation temperature is established manually or automatically for all sensors, and all parts of die mold are heated by electric heating elements up to vulcanisation temperature. Then mechanical rubber product is vulcanised. Device for method realisation comprises vertical vulcanisation boiler and die mold. Electric heating elements are located on internal surface of vertical vulcanisation boiler in three points: above upper cover, along cylindrical part and under lower cover of die mold. Electric heating elements are controlled by sensors, in the form of needle thermocouples that register temperature of each part of die mold. Sensors are mounted directly on each part of die mold.

EFFECT: provision of even heating of all parts of die mold and maintenance of permanent temperature in process of mechanical rubber product vulcanisation.
