Resin molding device, and method for producing resin molded article

A resin molding apparatus comprising:

• a mold including an upper mold and a lower mold and having a cavity formed in at least one of the upper mold and the lower mold;
• a clamping mechanism that clamps the upper mold and the lower mold;
• a pot block provided in the lower mold and formed with a pot that houses a resin material;
• a transfer mechanism that moves a plunger in the pot and injects the resin material into the cavity;
• and
• a conveying mechanism that unloads a resin molded product after resin molding from the lower mold,
• wherein
• the pot block includes an overhang overhanging between at least a part of the resin molded product and the upper mold,
• the conveying mechanism includes:
• a first holder that holds the resin molded product;
• a second holder that holds an unnecessary resin on the pot block;
• a first lifting movement mechanism that lifts the first holder such that the resin molded product held by the first holder moves upward under the overhang;
• and
• a horizontal movement mechanism that moves the first holder in a horizontal direction such that the resin molded product held by the first holder moves outward with respect to the overhang in a state where the first holder is lifted by the first lifting movement mechanism, and
• the lower mold is lowered by the clamping mechanism and the plunger is lifted with respect to the lower mold by the transfer mechanism, in a state where the resin molded product is moved outward with respect to the overhang and the second holder is in contact with the unnecessary resin on the pot block.
