PROBLEM TO BE SOLVED: To solve such a problem that a pot might be damaged in a resin mold apparatus in which a diameter of a cull is reduced smaller than hat of the pot. SOLUTION: The resin mold apparatus comprises a lower mold 1 in which a cylindrical pot 2 is passed through, and an upper mold 5 having the cull 6 in which a diameter of an opening is a diameter of an intermediate value between an inner diameter and an outer diameter of the pot 2 and the cull 6 is concentrically disposed with the pot 2 to relatively approach to or separate from the mold 1 in such a manner that an annular recess 11 opposed to an end face of the pot 2 is formed at a peripheral edge of the opening of the cull 6. |
