摘要： PROBLEM TO BE SOLVED: To facilitate a setup operation by almost eliminating the need for adjustment of a contact condition between the nozzle tip of a cold runner apparatus and a port for injecting a molding material into a cavity by pressing the nozzle tip to the injection port side with the feed pressure of the molding material and preventing the leakage of the molding material such as a rubber. SOLUTION: An injection molding die has a metallic die 10 comprising the upper and lower dies 12 and 13 to form a cavity 11, a cold runner block 20 and a nozzle block 30. The nozzle block is composed such that: a cylindrical piece 33 is fixed to the inner hole 32 of a nozzle body 31 by a screw means; a nozzle piece 35 having a gate 38 is loosely fitted to the inside of the cylindrical piece 33 and is provided so as to be able to protrude or retreat its lower end protruded downward; and the lower end face of the nozzle piece 35 is brought into press-contact with the periphery of the port 15 for injecting a molding material into the cavity by the feed pressure of the material.
