METHOD AND DEVICE FOR PRODUCING TIRE MOLD

摘要

PURPOSE: To provide a tire mold free from a crack, easy to assemble, having heat conductivity, easy in the removal of gas and made inexpensively and rapidly in forming a mold segment for the tire mold by spraying a molten atomized metal on a mold to form a metal shell and reinforcing the shell with a resin backing. CONSTITUTION: A shell 14 molded by alternately spraying a molten metal on two molds 10 provided on a spraying stand so as to form 20 layers, a backing plate 36 and side plates 38 form a modular shoe container 26 having a chamber 50. A heated liquid resin filler is mixed with metal particles to be injected in the shoe container to form a mold segment 56. During filling, gas is discharged from a groove. The member 36 is replaceable in order to form a mold segment different in size and a spacer for changing thickness is further provided. When a slide block is used, a backing member is unnecessary.
