PURPOSE: A mold for forming a paper container and a forming device thereof are provided to remarkably reduce an error rate when a paper container is formed by preventing stress concentration. CONSTITUTION: A mold for forming a paper container comprises a base core (200'), a main core (210), a center core (220), a fixed stripper (230). The base core is fixed to a fixed mold frame of a forming device. The main core has a first flat surface (211), a curved surface (212), and a first inclined surface (213). The first flat surface corresponds to the bottom surface of a base portion (2) of a paper container. The curved surface and the first inclined surface correspond to the bottom surfaces of an upward curved portion (5) and an extended inclined portion (2) of the paper container. A push pin (221) penetrating through the main core and the base core is formed on the bottom of the center core and slides in a vertical direction. The fixed stripper slides along the edge of the main core. A support (233) is protruding upward from one side of the fixed stripper. |
