A pore-free tire segmented mold pattern block (100) and a segmented mold are provided. The pore-free tire segmented mold pattern block (100) is used for forming a tire segmented mold. The pattern block (100) comprises pattern pieces (1) that are stacked one on top the other. The pattern block (100) has an exhaust channel (20) communicated with an inner circumference surface (11) of each pattern piece (1) and an end surface (12) of the pattern block. The exhaust channel (20) comprises axial exhaust holes (27) that are axially disposed on the pattern block (100), communicate each pattern piece (1), and are communicated with the end surface (12) of the pattern block. Also disclosed is a cleaning method for the pore-free tire segmented mold pattern block (100) and the segmented mold. When the mold is cleaned, the exhaust channel (20) is used as a cleaning channel, and the axial exhaust holes (27) of the exhaust channel are used as an entrance for a cleaning medium. Through the foregoing structure, an approximately closed container is formed by an inner cavity (200) of the mold. An organic solution is injected into the inner cavity (200) of the mold through a cleaning hole. Under the effect of certain pressure, the organic solution is discharged through an exhaust gap (11). A discharging process is a process of cleaning the exhaust gap (11). By using the cleaning method, a glue scale is removed more thoroughly and effectively, an operation is easy, and the cleaning cost is low. |
