DEVICE FOR MANUFACTURE OF RUBBER PRODUCTS Russian patent published in 2009 - IPC B29C33/00 

FIELD: technological processes.

SUBSTANCE: invention is related to equipment for manufacture of rubber technical products by method of compression pressing and vulcanisation in detachable die molds. Technical result is provided by device that consists of press having upper fixed plate and lower fixed plate. Upper plate limits movement of die mold pressed by lower press plate and together with electric heater forms vulcaniser. Die mold is installed in hollow sleeve, which by means of indent is fixed to bracket fastened on lower press part. Via hollow cylindrical sleeve with die mold installed in it axial force is transferred from lower movable plate of press to die mold. Electric heater of vulcaniser that heats die mold up to vulcanisation temperature represents electric heating element with ceramic insulator, which is spirally wound around cylindrically shaped body. Heater temperature is monitored by temperature detector. Device comprises thermostat made of set of fire-resistant incombustible heat insulation materials and is closed with jacket. For loading and unloading of die molds into sleeve outside press and heater action zone, and also for opening of hot die mold, device is equipped with pneumatic cylinders. All pneumatic cylinders are controlled by electric pneumatic valves and air distributor by commands coming from control unit. Monitoring of air pressure value in press is done by pressure detector. All technological process of rubber product making is displayed and recorded in computer memory.

EFFECT: creation of vulcanisation press that makes it possible to produce minor products with high extent of accuracy with simultaneous pressing and vulcanisation of rubber technical product, and also increased safety engineering of operation in vulcanisation press and saving of technological heat and possibility to create robotised section for production of rubber technical products.
