う構成してなることを特徴とする射出成形における滞留
材料の漏出防止装置。In the passage of the sprue 3 of the mold 1, there is a two-part shutoff valve 7.
8 was slidably disposed so as to be able to be separated and opened, and a through hole 9 was bored in the cut-off valve 7.8 which met and communicated with the sprue 3 in the connected state, and molding material was injected and supplied to the mold 1. Afterwards, the shutoff valve 7.8 is opened to shut off the sprue 3, and at the same time, the negative pressure chamber 1'0 generated in the gap of the opened shutoff valve 7.8 is made to communicate with the passage on the gate 5 side of the sprue 3.
