CAST MOLDING DEVICE AND CASTING METHOD

摘要

PROBLEM TO BE SOLVED: To obtain an inner hole of a cast in a cast molding device provided with a pressure pin.SOLUTION: A cast molding device 50 has a cast removal pin 92 for forming an inner hole in a cast. The cast removal pin 92 is a hollow body, and a pressurization pin 96 is penetrated through the interior of the hollow body. The pressurization pin 96 is given oscillation from an oscillator 120 of a microoscillation machine 118 via an oscillation transmission member 112. The oscillation further propagates from the pressurization pin 96 into the cast removal pin 92 and then propagate into a part enclosing the cast removal pin 92 in a molten metal 66 cast into a cavity 60.
