Pores without tire for the split pattern mass (pore-freetiresegmentedmoldpatternblock), split-type and the cleaning method

摘要

The present invention provides split pattern mass for the pores without tire, the split and the cleaning method. In the pore without split patterns chunks tire constituting a split mold for a tire, the pattern mass comprises a plurality of patterns pieces are stacked in a vertical direction, the end faces of the inner and patterns masses of each pattern piece in the pattern mass The provided with an exhaust passage communicating with said exhaust passage, said provided axially pattern mass, the axial exhaust hole in the end face in communication patterns lump together each pattern piece communicating is provided, the exhaust passage is made to function as a cleaning passage when cleaning the mold, the axial exhaust holes in the exhaust passage is the entrance of the cleaning medium. According to the above configuration, to form a mold cavity in the container such as a closed shape, the organic solution is injected into the mold cavity through the cleaning hole, to discharge the organic solvent through the exhaust gap at a constant pressure and can be, the process of discharging is a process of washing the exhaust clearance. According to this cleaning method, it is possible to more fully effectively remove plaque rubber and is easy to operate, clean low cost.
