Embodiment
[0077] Next, embodiments of the rubber mold for resin molding, the resin molding apparatus, and the resin molding method of the present invention will be described with reference to the drawings.
[0078] Such as Figure 1 to Figure 4 As shown, the rubber mold 2 for resin molding of this example forms a cavity 213 for pressurizing and filling the thermoplastic resin 5 in a molten state. The rubber mold 2 is composed of a core box 21 made of a rubber material and forming a cavity 213 and a base mold 22 made of a rubber material and having a structure 220 in which the core box 21 is disposed. shape. The core box 21 combines a plurality of divided mold parts 211 (a pair of divided mold parts 211 in this example) on a parting surface 212 for opening a cavity 213 . The base model 22 has at least a lower surface portion 221 and a pair of first side surfaces 222 erected from two opposite sides of the lower surface portion 211, and the pair of first side surfaces 222 are formed on a p...
