A method for detaching elastomer particles that adhere on microvalves (3) disposed on the internal surface of a vehicle tire mold (2) comprises vibrating the microvalve (3) 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 (3).

Invention is a cleaning assembly for cleaning a tire curing mould comprising a turntable (20) mounted on a base plate (12); a cleaning arm (50) extending on the turntable (20) in a movable manner and configured to blow dry ice, and an insulation hood (60) surrounding the cleaning arm (50) wherein the base plate (12) is having an adapter support (16) configured to be gradually widen or narrow for being adapted to the insulation hoods with different diameters on the base plate.

The invention is a cleaning method for the production of vehicle tire full-molds having profile. The method as the subject of the invention comprising the process steps respectively, the contaminated full-mold (1) is taken a pre-treatment with an ultrasonic cleaning apparatus (10), depurated full-mold (2) is re-cleaned by putting to dry ice process in a first cleaning station (20), cleaning of the full-mold with preferably multiple number of ultrasonic devices (51, 52, 53) by immersing into a cleaning liquid (50) in a second cleaning station (40), rinsing by taken in to a rinsing station (60), putting to another process by taken in to a passivation station (70), and drying by taken in to a drying station (80).

Invention is a cleaning robot for cleaning the inner surfaces (5) of the half mold (4) of tire curing molds comprising a basket (10) wherein a lifting arm (50) placed in a manner pivotal on a proximal end (52), the lifting arm (50) pivoted on a distal end (54) of a support arm (70). The cleaning robot fits completely into the basket (10) when the positioned as close and comprising a movable head (80) having a nozzle (82) coupled in a manner to establish fluid communication to the dry ice inlet (84) and located at the distal end (76) of the support arm (70) and a free end which is configured movably closer to the inner surface (5) such as at a vicinity of the inner surface (5) along the contour of its when the positioned as open.

Invention is a cleaning machine for tire curing sidewall (80) that comprises a basket (10), a rotational base (20) which mounted into thereof, a nozzle (60) provided in a movable manner on the rotational base (20), of extending towards the open side of the basket (10) and having an intake (63) connected to inlet (62) in a fluid transferrable manner. The cleaning machine comprises a rotating joint (40) which mounted radially to the outward direction on the rotational base (20) and a telescopic arm (50) which carrying the nozzle (60) at the free end thereof and which of fastened on a rotational base (20) with the rotating joint (40).

A method is provided for forming an impermeable barrier layer on an inner tire surface of a tire. An assembly is also provided along with a kit for forming an impermeable barrier layer on an inner tire surface of a tire accordingly.

A tire vulcanization mold in which a surface roughness in the groove molding portion of the tread molding surface is made smaller than a surface roughness in the land portion molding portion, in which a surface roughness in the groove molding portion is minimized to 0.12 μm or less in a range including at least a main groove molding portion, and in which a surface roughness in the land portion molding portion is made to be 3.2 μm or more, is used to manufacture a tire, and when cleaning the tread molding surface, the tread molding surface is irradiated with a laser beam to remove contaminant adhered to the tread molding surface.

An automatic plant for cleaning moulds for tyres, wherein the moulds are constituted of sectors and cheeks, includes an apparatus for internal cleaning of sectors and cheeks and an apparatus for external cleaning of sectors and cheeks. The apparatus for internal cleaning of sectors and cheeks comprises fixing means for sectors and cheeks in a stable treatment position, a generating device for generating ultrasonic vibrations, transmitting means for transmitting the vibrations from the device to the sector or cheek treated, in such a way as to carry out cleaning of sectors or cheeks by subjecting them to vibrations.

Vents and micro-structures of rubber molds may become clogged with rubber that is difficult to remove. These vents and micro-structures can be cleaned of rubber, even if heat aged, by subjecting the mold to high temperatures in the presence of a solvent to devulcanize any rubber present. If the rubber used with the mold being cleaned includes carbon black, a solvent may be used to dissolve the devulcanized polymer, leaving the carbon black which can be removed by water jets or other cleaning means.

Provided is a mold cleaning system. On the basis of an identification mark assigned to a mold and detected by a mark detector when cleaning the mold, the mold cleaning system obtains shape data for the molding surface of the mold which is stored in a database, and on the basis of the obtained shape data, the mold cleaning system controls the movement of arms using the control device, moves a laser head along the molding surface thereof while irradiating with a laser beam supplied by a laser oscillator, and as a result, removes the dirt adhered to the molding surface.
