摘要

PURPOSE:To facilitate adjustment for aligning the axial line of a raw material feeding hole and the axial line of a plunger inserted therein in a mold and to improve durability of the plunger in a transfer molding machine. CONSTITUTION:An annular groove 21 is provided on the outer peripheral face of the apex part of a plunger 19 pushed into a raw material feeding hole and a ring body 22 tightly fitting to the raw material feeding hole is mounted in such a way that the ring body is freely movable in the right angle direction to the axial line of the plunger and a communicating hole 23 communicated with the annular groove is provided in such a way that the communicating hole is opened on the apex face 19a of the plunger.
