A method for detaching elastomer particles that adhere on microvalves () disposed on the internal surface of a vehicle tire mold () comprises vibrating the microvalve () at a constant amplitude ranging between approximately 0.05 and 0.2 mm and at a frequency ranging between 20,000 and 30,000 Hz during the detachment of the particles from the microvalve ().

Method for detaching elastomer particles

A method for cleaning a vulcanization mold for tires in a curing press uses device having a collaborative mobile robot and incorporating a computer program. The robot includes an autonomous mobile platform mounted on drive wheels and having batteries supplying electricity, a dry ice dispenser, sensors for identifying the location of the mold to be cleaned, and motors ensuring its displacement between a storage location of the device and the mold to be cleaned and the displacement of an articulated mobile arm of the robot. The robot bears a nozzle for spraying dry ice from the dispenser. The device comprises means for communication with a control unit. The control unit sends a mission instruction to the device, which navigates between a storage location and the location of the mold and automatically cleans the vulcanization mold.
