Abstract
A multilayer molded product is formed by a multilayer molding apparatus including: a plurality of injection units on the part of a fixed platen; a moving platen caused to open and close the molds by a mold clamping unit; and a rotary platen mounted with different mold cavities on its surfaces facing the fixed platen and the moving platen respectively and having a mechanism enabling to move between the fixed platen and the moving platen in a mold opening/closing direction in conjunction with a mold opening/closing operation, stop at an arbitrary position, and rotate. The multilayer molded product is formed according to a multilayer molding method of switching the cavity to be formed by a mold core mounted on the fixed platen and a mold cavity mounted on the rotary platen by rotating the rotary platen, and performing injection-filling into the respective cavities from the plurality of injection units in accordance with preset injection patterns.
