PROBLEM TO BE SOLVED: To provide an insert molding component which can prevent a weld from being generated without giving rise to cracks in a resin region. SOLUTION: Two insert members 4A and 4B are partially exposed to the outside, and the resin 2aa is cross-linked in the center of the insert members 4A and 4B and interconnected in one piece with a surrounding resin. Thus, the insert members 4A and 4B are securely anchored. In addition, a tunnel gate 8b for packing the resin at an acute angle, is formed in a position G located on a perpendicular area Y to the surface X, in the opening/closing direction, of a mold and at the same time, on the side of the insert member, in the extended direction between the insert members 4A and 4B. Next, the resin is poured through the tunnel gate 8b to form the cross-linked resin 2aa and thereby, the insert members 4A and 4B are securely anchored. The insert molding component 2 has an elliptical gate mark 8bb left at the time of cutting off a sprue runner after the insertion through the tunnel gate 8b. COPYRIGHT: (C)2007,JPO&INPIT |
