RESIN INJECTION-MOLDED OBJECT, INJECTION MOLD, SYRINGE SLEEVE AND INJECTION MOLD FOR SYRINGE SLEEVE

摘要

PROBLEM TO BE SOLVED: To provide a resin injection-molded object free from burrs generated due to a runner near a gate position, and an injection mold for molding the resin injection-molded object.;SOLUTION: This injection mold 1 is for the resin injection-molded object with a draft angle formed on the exterior surface and has a cavity 2 which forms at least an exterior shape of the injection-molded object and also assumes the draft angle. The cavity 2 has an undercut formation part 20 with a scarfed area 21 as a back draft to the draft angle. In addition, a molten resin injection gate 5 is formed in the tilted area 21 of the undercut formation part 20.;COPYRIGHT: (C)2007,JPO&INPIT
