PURPOSE:To obtain the molding without occurrence of flash, even if a long member has dimensional error or fluctuation by achieving injection molding, while providing a cooling device adjacent to the contact part of an injection mold with the long member and cooling said contact part. CONSTITUTION:The long member 6 in which a resin part is formed by extruding, feeding a metal part 2 and decorative films 3, 4 to an extrusion mold, is out into a specified length, and its final end is inserted into the injection mold composed of a cavity mold 8 and a core mold 9 and then, said molds are clamped. Then, the resin is injected into a cavity 12 through a gate 11 from an injection nozzle such that thermal conductive material 16 is caused to be in contact with the adjacent final end of the long member 6. Low temperature cooling fluid is caused to flow into a cooling fluid chamber 17 from a fluid inlet 18, and the contact part 13 of the fluid with the long member 6 is cooled. The resin adjacent to the contact part 13 becomes high viscous by cooling, and the flowing out from the contact part 13 is prevented. Flash 15 never occur at a relief part 14. |
