<P>PROBLEM TO BE SOLVED: To enable control of injection amount to certainly fill up regular molding space with resin materials without using discarded cavity etc., even for a molding of a small capacity like a clip. <P>SOLUTION: An injection molding apparatus which injects resin materials to a polymerization part 42 of two members 40 and 41, and directly molds a clip to combine two members through a coupling hole 43 which penetrates the resin materials the polymerization part, includes: an upper mold 34 and a lower mold 36 which are arranged at both end sides of the coupling hole 43 holding the polymerization part 42 of two members 40 and 41 and can compose a molding space 44 sealed including inside of the coupling hole; and an injection machine which injects the resin material from one side of these upper mold and lower mold to the molding space 44. <P>COPYRIGHT: (C)2012,JPO&INPIT |
