Injection-molding mold for making a resin window panel

An injection-molding mold (9) for making a vehicle resin window panel (1) which has a panel body (3) made of a transparent or semi-transparent first resin (R1), and an annular frame (5) made of an opaque second resin (R2) and formed integrally with a periphery of a back surface side of the panel body (3), and in which an area surrounded by the frame (5) forms a window (7), the injection-molding mold (9) comprising:

• a fixed mold (11) which molds a front surface side of the window panel (1);
• and
• a movable mold (13) which faces the fixed mold (11) and is movable back and forth with respect to the fixed mold (11), and which molds a back surface side of the window panel (1), wherein
• the movable mold (13) includes
• a central mold (23) which molds a back surface side of the panel body (3) corresponding to the window (7),
• separate first sliding molds (25) positioned around the central mold (23), and forming a first cavity (27) for molding the panel body (3), together with the central mold (23) and the fixed mold (11), and
• a second sliding mold (29) positioned so as to surround the central mold (23), and forming a second cavity (33) for molding the frame (5), together with the panel body (3) molded in the first cavity (27) and held on the fixed mold (11),
• each of the first sliding molds (25) is movable back and forth in a direction intersecting a back-and-forth direction of the movable mold (13), comes into contact with a periphery of the central mold (23) when the first sliding molds (25) move forward to form the first cavity (27), and avoids interference with the second sliding mold (29) when the first sliding molds (25) move back to form the second cavity (33), and
• the second sliding mold (29) is movable back and forth in the back-and-forth direction of the movable mold (13), allows a forward movement of the first sliding molds (25) when the second sliding mold (29) moves back to form the first cavity (27), and comes into contact with an inner peripheral edge and an outer peripheral edge of the panel body (3) held on the fixed mold (11), thereby forming sealing portions (29b, 29c), when the second sliding mold (29) moves forward to form the second cavity (33).
