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...

Abstract

A resin molding rubber mold (2) comprises a cavity (213) into which a pressurized molten thermoplastic resin is placed. The rubber mold (2) comprises a core mold (21) consisting of a rubber material and having the cavity (213) formed therein, and also comprises a base mold (22) consisting of a rubber material and having a shape for allowing the core mold (21) to be placed in the base mold. The core mold (21) is formed by combining together a pair of split molds (211) along split surfaces (212) for opening the cavity (213). The base mold (22) has a lower surface section (221) and a pair of first side surface sections (222) which are formed on both sides of the direction in which the pair of split molds (211) is combined together.

Description

technical field [0001] The present invention relates to a rubber mold for resin molding for obtaining molded articles of thermoplastic resin, a resin molding device, and a resin molding method. Background technique [0002] As a method of obtaining a resin molded article of a predetermined shape from a thermoplastic resin, there are generally various molding methods such as injection molding, blow molding, extrusion molding, and press molding. [0003] In contrast, for example, Patent Document 1 discloses a resin molding method in which a resin molded article made of a thermoplastic resin is molded by vacuum injection molding using a molding die (rubber mold) made of rubber such as silicone rubber. The molding die can selectively heat the thermoplastic resin. In this resin molding method, when filling a molten thermoplastic resin into the cavity of a molding die, the thermoplastic resin is irradiated through the molding die with electromagnetic waves including a wavelength ...
