Claims

1. A cleaning method for the production of vehicle tire full-molds having profile, characterized in that the process steps comprising respectively, the contaminated full-mold (1) is taken a pre-treatment with at least one 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).

2. A cleaning method according to claim 1, wherein the step of process comprises the depurated full-mold (2) is suspended on a rack within a basket (54) in a cabinet (30) having cleaning liquid (50) at the second cleaning station (20).

3. A cleaning process according to any one of the preceding claims, wherein a washing step of process via spraying from at least one jet (62) onto the depurated full-mold (2) at the rinsing station (60).

4. A cleaning process according to any one of the preceding claims, wherein depurated full-mold (2) is taken into a cabinet (30) for a process at the first cleaning station (10) in the step of process.

DETAILED DESCRIPTION OF THE INVENTION

[0015] The process steps of the application which is subject matter of the invention as an illustration of the cleaning method is shown in FIG. 1 schematically. Accordingly, contaminated full-mold (1) is taken a pre-treatment with an ultrasonic cleaning apparatus (10), so movement of contamination by eliminating the dirt on full-molds that occurred in the valves at the air ventilation openings is achieved. From here, the full-mold (2) is taken into the first cleaning station (20) via dry ice blasting through a cabin (30). The period of the ultrasonic process is shortened on the second ultrasonic station (40) by providing elimination of coarse dirt and contamination via process of dry ice application. Thus, through increase in the contamination period, the usage efficiency of the cleaning liquid (50) of the bath having chemicals is increased. In the one embodiment of the invention, frequency of application increases in the same bath prepared at the second cleaning station (40).

[0016] Then the full-mold (2) is immersed into a basket (54) is situated in a a loaded tank with cleaning fluid (50) at the second cleaning station (40), and is cleaned by means of the ultrasonic device (51, 52, 53) are placed around the basket (54) which is actuated by a drive system. The dirth and contamination adhered on the surface are dissolved owing to the effect inside cleaning fluid (50) generated by the ultrasonic device (51, 52, 53) wherein the cleaning operation. Furthermore, the churning influence due to movable basket (54) during the cleaning of full-mold (2) provides removal of the contamination from the surface of the full-molds.

[0017] Besides, lower prices reduction is takes placed in the amount of cleaning liquid (50) containing waste water and waste chemicals discharged from the second cleaning station provides lower cost for the process. Likewise, providing this cost reduction also ecologically decreases the pollution of environment.

[0018] After the ultrasonic cleaning process at least one depurated full-mold (2) having profile preferably multiple depurated full-mold (2) having a profile is taken in to rinsing station (60) and is washed by spraying water from jet (64) by means of at least one motor (61). Meanwhile, usage of optimum amount of wash water is provided by means of water recirculation formed by a circulation pump (62). After this step, full-mold (2) is taken to a passivation station where spraying is employed from pintle nozzle(72), and finally in the drying station (80) where spraying hot air is employed from nozzles (82).

[0019] A preferred application of the invention has a microprocessor control unit is used for operating with adjusting the value amounts of the temperature, pressure, time, ultrasonic wave and movement in the stations (20, 40, 60, 70, 80). A preferred application of the invention has a PLC (Programmable Logic Controller) is used for operating with adjusting the value amounts of the temperature, pressure, time, ultrasonic wave and movement in the stations (20, 40, 60, 70, 80).
