金型。[Claims for Utility Model Registration] (1) A lower mold, an upper mold that is clamped to the lower mold, and a plurality of intermediate molds arranged between the lower mold and the upper mold,
In a mold for molding the end portion of the preform, the end portion of the preform is inserted into the cavity, and the end portion of the preform is inserted between the intermediate mold and the lower mold and/or between the intermediate molds. A biasing member for biasing the intermediate mold in the direction of opening the mold is provided between the upper mold and the intermediate mold, and the upper mold and the intermediate mold press the intermediate mold against the biasing force of the biasing member when the molds are closed. the intermediate mold is biased by the biasing member by releasing mold clamping pressure when inserting the preform;
A molding die characterized in that a gap is formed between the preform and the intermediate mold. (2) The molding die according to claim 1, wherein the gap between the preform and the intermediate mold is about 0.5 to 1.0 mm. (3) The molding die according to claim 1, wherein the upper mold and the intermediate mold have tapered surfaces that are in sliding contact with each other, and the tapered surfaces constitute a mold clamping mechanism.
