Abstract:
(EN) According to the invention, slit forming parts are easily formed on split faces of split molds, and changes in a slit vent formed by the slit forming parts are suppressed. Split faces (21), (22) including slit forming parts (23) are formed on split molds (20). The split faces (21), (22) of the split molds (20) are plated to coat the split faces (21), (22), on which the slit forming parts (23) are formed, with plating films (40). The plurality of split molds (20) are combined together, with the split faces (21), (22) thereof facing each other, to mold a rubber article. The slit forming parts (23) of the split faces (21), (22) form a slit vent (30) between the split molds (20).
(FR) Selon l'invention, des parties de formation de fente sont facilement formées sur les faces fendues de moules fendus et des variations d'une fente d'aération formée par les parties de formation de fente sont supprimées. Des faces fendues (21), (22) comprenant des parties (23) de formation de fentes sont formées sur des moules fendus (20). Les faces fendues (21), (22) des moules fendus (20) sont plaquées pour revêtir les faces fendues (21), (22), sur lesquelles les parties (23) de formation de fentes sont formées, de films de placage (40). La pluralité de moules fendus (20) sont combinés les uns avec les autres, leurs faces fendues (21), (22) étant en regard les unes des autres, pour mouler un article en caoutchouc. Les parties de formation de fentes (23) des faces fendues (21), (22) forment une fente d'aération (30) entre les moules fendus (20).
(JA) 分割モールドの分割面にスリット形成部を容易に形成し、スリット形成部により形成されるスリットベントの変化を抑制する。 スリット形成部(23)を含む分割面(21)、(22)を分割モールド(20)に形成する。分割モールド(20)の分割面(21)、(22)にメッキを施して、スリット形成部(23)が形成された分割面(21)、(22)をメッキ皮膜(40)で被覆する。複数の分割モールド(20)は、分割面(21)、(22)を対向させて組み合わされてゴム物品を成形する。分割面(21)、(22)のスリット形成部(23)は、分割モールド(20)の間にスリットベント(30)を形成する。
