Abstract
In a method for cleaning profile molds for producing tire profiles on treads of vehicle tires, the profile molds are cleaned in rinsing suds by using ultrasound. The profile molds are moved successively through a pre-cleaning and a primary cleaning chamber between which they are rinsed in a rinsing bath. After cleaning in the primary cleaning chamber, the profile molds are checked with respect to remaining contaminants and valves disposed in air vent openings in the profile molds are inspected and loosened by ultrasound application to ensure their mobility. Subsequently, the profile molds are cleaned again. The invention also relates to an arrangement for carrying out the method.
Claims8
A cleaning method for cleaning profile molds for producing tire profiles on treads of vehicle tires, the profile molds having recesses with openings for discharging air and gases when pressing the tire profiles, and the openings including movable valves which are to be opened and closed, the method comprising the steps of:
- cleaning the profile molds in rinsing suds in a primary cleaning chamber by applying ultrasound, checking the valves after the first cleaning step for remaining contaminants and inspecting the valves and, if stuck loosening the valves to ensure the mobility of the same by using ultrasound, and subsequently again cleaning the profile molds in a secondary cleaning chamber.
A cleaning arrangement for cleaning profile molds for producing tire profiles on treads of vehicle tires, the molds having openings for discharging air and gases when pressing the tire profiles, with movable valves disposed in the openings for opening and closing the openings, the cleaning arrangement comprising a primary cleaning chamber (8) which, for cleaning the profile molds in rinsing suds (13), includes ultrasound transducers (15a, 15b) which generate ultrasound and are used in the rinsing suds, for the profile molds to be cleaned in the primary cleaning chamber (8), an inspection unit (11) arranged downstream of the primary cleaning chamber (8) for checking for remaining contaminants in the profile molds, an inspection unit (11) for checking the mobility of the valves and which, for loosening the same, includes an ultrasound device (17), and a secondary cleaning chamber (9) arranged downstream of the inspection unit (11) for a secondary cleaning of the profile molds.
