Abstract

PURPOSE:To manufacture a highly accurate tyre mold by making a groove that broadens toward the interior at the position where a lug of a holder is provided, and installing a mold having a precise tyre pattern inside of the holder opposing the groove and the lug part of the tyre pattern, and pouring molten substance into a space between the mold and holder. CONSTITUTION:A holder 12 is so cast that the inner face 12a becomes a face that is slightly retired from an inner face 11b of the mold 11 which is to be obtained finally, and a groove 12b that broadens toward the interior is provided at a position where a lug part 11a is to be fitted. A mold 13 in which a precise type pattern is formed is placed at a position that faces the inner face 12a of the holder 12. By installing the mold 13, a space 14 is formed between the inner face 12a of the holder 12 and the inner face 13a of the mold 13. At the same time, the lug part 13b of the mold 13 is opposed to the groove 12b. Next, molten substance is poured into the space 14 from a sprue 15 and the mold 13 is removed after cooling and solidification.
