MOLD APPARATUS AND RESIN MOLDING METHOD

摘要

The mold apparatus (1) includes: the stationary mold (12) of the mold main body (2) that molds the main body part (81); the rotary core (20) that molds the undercut part (82) and mold releases by rotationally moving in a direction separating from the undercut part (82); and the restricting core (40) that restricts movement of the rotary core (20) sandwiching between the stationary mold (12) and rotary core (20) during molding, and releases restriction of the rotary core (20) by moving in a direction exiting from between the stationary mold (12) and rotary core (20) during mold release of the rotary core (20) from the undercut part (82).
