| titleOfInvention | Metal mold for shoe sole molding |
| abstract | The present invention relates to a metal mold for shoe sole molding. Air holes and air channels are formed on the upper metal mold so as to prevent blockage and damage of the air holes and air channels caused by materials. Vacuum valve, thereby preventing product yellowing caused by reverse flow of external air during foam molding. In order to achieve the above object, the technical gist of the present invention is, for the metal mold for shoe sole forming that is made of an upper metal mold and a lower metal mold, wherein, the upper metal mold has a protrusion; the lower metal mold has a The molding groove into which the protrusion of the upper metal mold is inserted, the invention includes: a vent hole formed through the upper metal mold, and absorbing the air existing in the lower metal mold by the suction action of the vacuum pump installed outside. the air of the forming tank; and a vacuum valve, which is arranged in the air hole and prevents the reverse flow of external air. |
