Abstract

PURPOSE:To obtain injected or die-cast product without defects, by mounting the valve movable to a different direction from that of the axis of the degassing groove and also mounting the by-pass for degassing. CONSTITUTION:The injected or die-cast products are to be obtained by means of an apparatus, wherein a vlave 13 is so mounted that is can be moved to a different direction from that of the axis of a degassing groove 11 connected to a cavity 7 and a by-pass 19 is so mounted that it turns along the side of the valve 13. When the resins or the melted metals are injected into the cavity 7, the gases are exhausted to the outside through the degassing grooves 10, 11, by-pass 19, hole 3a and gas outlet 3b. Then the melted materials ascend in the degassing groove 10, 11, turn their direction in a chamber 12 and push themselves violently to the valve 13, to move the valve 13 to the right and settle on the valve seat 13b. As the opening of the by-pass 19 to the chamber 12 is closed by the valve 13, the melted materials do not leak outside.
