PROBLEM TO BE SOLVED: To withdraw, while attempting to simplify and miniaturize injection molding molds, a pin from a hole formed on a molding without entailing the deformation of the molding.SOLUTION: The injection molding molds of the present invention comprises: a pair of molds 11 and 12; an injection space 13 formed between the pair of molds 11 and 12; and a pin 61 extractable from and retractable into the injection space 13 in which a molten resin is injected in a state where the pin 61 abuts into the injection space 13 on a mold fastening occasion so as to mold a molding within the injection space 13 and to form, on the molding, a hole corresponding to the pin 61. The injection molding molds further comprises: a first slide unit 62 elastically supported on one mold 11 and sliding along the mold opening direction concomitantly with a mold opening action; a second slide unit 63 elastically supported on the first slide unit 62 and mobilized, concomitantly with the slide action of the first slide unit 62 along the mold opening direction, along a direction for withdrawing the pin 61 from the hole; and a regulating unit 64 configured on the other mold 12 for regulating, upon the commencement of the mold opening action, the slide action of the first slide unit 62 along the mold opening direction. |
