Abstract

A nozzle (26) for a hot runner mold (10) having a cavity (29) and a runner (27) formed in a body (24) thereof and communicating with the cavity. The nozzle leads to the runner and has a heating means (36), a heat-insulating groove (37), and a heat transmitting ring (38) provided on an outer peripheral surface (35) thereof. The nozzle has a flow passageway (33) formed therein. The heating means, the groove, and the ring are arranged in order along a direction of flow of resin (51) within the passageway. The groove serves to prevent heat generated by the heating means from being transferred to a distal end portion (43a) of the nozzle. The ring serves to release the heat of the distal end portion to the body. With this arrangement, the resulting molded product (11) can be removed from the mold without causing any stringiness between the runner and the distal end portion.
