Abstract:
PROBLEM TO BE SOLVED: To accurately produce a porous body having a plurality of pores. SOLUTION: A production device comprises a fixed mold 2 having a sub cavity C2, a core (movable mold) 4 forming a main cavity C1 between the core 4 and the fixed mold 2 by moving backward in a direction away from the fixed mold 2, a molding pin group 10 having its tip end facing the inside of the main cavity C1 by passing slidably through the core 4, an injection device for filling a molding material into the sub cavity C2, and a braking mechanism for controlling the movement of the core 4 so that the core 4 moving backward in a direction away from the fixed mold 2 by the filling pressure of the molding material moves while pressuring the molding material in the main cavity C1. A gate 13 injecting the molding material R into the sub cavity C2 is arranged at a position facing the surrounding of the molding pin group communicating with the sub cavity C2.
