Mold having a gas release structure and the structure of the mold

It is constituted by a sliding member acceptor having a sliding member and a gas outlet for receiving a pressing force by the bottomed hole and has a side surface opening elastic body, the molten material flow passage or cavity in the mold of the molten material flow passage in the gas discharge structure mounted near the ends, forming a gap S1 to S5 flow front portion of the molten mass enters, also reliably actuate the sliding member by expanding the volume of the blind hole, the sliding member bottom surface was an inclined surface SF1, the left and right outer sides of the right and left in the side surface and the sliding member of the sliding member acceptor as an inclined surface SF2, SF3, SF4, SF5, to block the exit of the molten mass by the action of the respective inclined surfaces It is configured. Then, a blind hole, side opening, the ejector pin for taking out the molten material filled in the gas outlet.
