A recently granted patent (Publication Number: US11969922B2) discloses a method for manufacturing resin molded products using a specialized resin molding apparatus. The apparatus includes a molding mold with a mold wedge mechanism and a mold cavity block driving mechanism. The method involves setting the height position of the mold cavity block, injecting resin into the mold cavity, and performing resin molding by adjusting the depth of the mold cavity using the wedge mechanism and driving mechanism. The apparatus also includes a plunger for resin injection and features such as mold clamping and mold releasing film for enhanced molding processes.

Furthermore, the method includes steps for adjusting the depth of the mold cavity, moving the cavity block towards or away from the other mold, and ensuring the proper positioning of the mold cavity block to avoid interference with objects to be molded. The patent emphasizes the precise control and manipulation of the mold cavity block to achieve accurate resin molding results. Additional features like the mold clamping mechanism and the use of mold releasing film contribute to the efficiency and quality of the resin molding process. Overall, the patent highlights a comprehensive method and apparatus for manufacturing resin molded products with a focus on precision and control throughout the molding process.
