Resin molding apparatus with metallic mask for substrate contact
A resin molding apparatus has been granted a patent (Publication Number: US11833722B2) with claims detailing its unique features. The apparatus includes a lower mold with a side surface member and a bottom surface member that can move up and down to form a cavity, an upper mold to hold a substrate, and a metallic mask designed to make partial contact with the side surface member and the substrate when the molds are clamped. The metallic mask is formed in the shape of the cavity and includes a flow portion for the pressurized resin material to flow through during molding.
The patent also covers a method of manufacturing a resin molded product using the described resin molding apparatus. The method involves placing the metallic mask in contact with the side surface member of the lower mold, clamping the molds together with a substrate in place, and pressurizing the resin material in the cavity to flow through the flow portion in the metallic mask. This innovative approach to resin molding aims to improve the efficiency and precision of the molding process, with the flow portion strategically located on the outer peripheral portion of the metallic mask for optimal resin flow control.
