In the injection molding mold, the hot chip is tightly fitted and supported in the tip fitting hole formed at the top of the hot chip storage part with a gap between the hot chip and the inner surface of the hot chip storage part, and the base end is hot at room temperature. An injection molding die characterized in that it is loosely fitted into a base end fitting hole formed in a runner block and supported to allow thermal expansion due to temperature rise during use. (2) The injection mold according to claim 1, wherein the bottom surface of the proximal end fitting hole and the proximal end surface of the hot chip come into contact with each other at high temperatures due to use. (3) The gap between the bottom of the proximal end fitting hole and the proximal end of the hot chip is 0.03 mm at high temperatures due to use.
The injection mold according to claim 2, which abuts on: (4) Claim 1, wherein a runner and a gate are formed between the tip of the hot chip storage section and the cavity.
The injection mold according to one of items 1 to 3. (5) Claim 1, wherein the hot runner block is provided on the mold body with a bolt via a spacer.
The injection mold according to one of items 1 to 4.
