Injected rubber mold and method for injected molding rubber footwear with lining

A rubber injection mold for rubber footwear with a lining, wherein the rubber injection mold is configured to overmold the lining on a footwear body shell, and the rubber injection mold comprises:

• a combined outer mold, comprising a first outer mold and a second outer mold which correspond to a footwear body, wherein the first outer mold and the second outer mold are drivable to move towards each other so as to close the combined outer mold and are drivable to move away from each other so as to open the combined outer mold, wherein the combined outer mold forms a footwear cavity when the combined outer mold is closed, and an inner wall of the first outer mold and an inner wall of the second outer mold define a first footwear body space for accommodating the footwear body shell;
• and
• an inner mold, covered with the lining, wherein the inner mold is configured to be placed in the footwear cavity and cooperate with the closed combined outer mold to adhere the lining to a surface of the footwear body shell in the first footwear body space,
• wherein the inner mold is provided with a guide groove, in which a movable insert is slidably arranged, the movable insert has an exposed part extending to an outer surface of the inner mold, and the exposed part is arranged corresponding to the mold closing part of the combined outer mold, and
• wherein the movable insert is configured to be driven to:
• before the combined outer mold is closed, move in the guide groove in a first direction until the exposed part retracts inward of the outer surface of the inner mold, providing a space for the lining to keep away from the combined outer mold when the combined outer mold is closed;
• and after the combined outer mold is closed, move in a second direction until the exposed part is flush with or protrudes from the outer surface of the inner mold, enabling the lining to be closely attached to the footwear body shell.
