摘要： PROBLEM TO BE SOLVED: To provide a hot runner mold structure which can mold a small circular disk by improving the important structure of a valve gate mechanism and/or the mold.
SOLUTION: This hot runner die structure is equipped with a valve gate mechanism which can fill a molten resin of a specified amount in a cavity by opening/closing the gate at the entrance of the cavity by a valve pin 13. In the hot runner mold structure, a straight guide part which guides the distal end of the valve pin when the gate is closed is provided on the mold side. At the same time, a resin release groove which releases the molten resin when the gate is closed is provided on the straight guide part. The outer diameter of the valve pin is set to be larger than the diameter of the gate, and the hot runner mold structure is constituted in such a manner that the gate is closed by the distal end surface of the valve pin.

CONSTITUTION:The mold surface side of an insert die 5 to be accommodated in the center of a base mold 3 is formed on a round recessed section 7 and a guide component 11 of short cylindrical shape is provided projectingly on the center of the recessed section, and a mirror board 16 which is mounted on the mold surface by means of an inner peripheral ring 18 fitted with a stamper 21 fitted in its center and an outer peripheral ring 20 fitted on the periphery, is fitted in the recessed section 7 by fitting the inner peripheral ring 18 in the guide component 11 and fixed in the insert die 5 integrally. Thus, the stamper 21 can be replaced by using the insert die 5 removed from a base mold 3 as a supporting bed, and if necessary, the mirror bed 16 is released from the insert die 5 together with the stamper 21 for the replacement of the stamper. The replacement of the stamper 21 can be carried out easily simply by removing the mirror board 16 in said arrangement.
