たノズル用ヒーター構造。 In a heater for a hot chip nozzle for a synthetic resin mold, the outer peripheral surface forms a male taper part, a slotted part for tightening is formed on the side wall, and a tightening screw part is formed at the end of the side wall. An electric heating element is buried inside a cylindrical fitting that is inserted and fixed into the hot chip nozzle, and a cylindrical good heat conductive member that has a female tapered inner surface that is inserted into the male tapered part. A heating part whose outer peripheral surface is made of a heat-resistant material having poorer heat conduction than the heat-conducting member forms a pair of assembled bodies, and is configured to be attached to and detached from the nozzle using a tightening fitting. Heater structure for nozzle.
