Document Type and Number:
Japanese Patent JP2023066641
Kind Code:
A
Abstract:
To provide a local pressurization device which can suitably use a pressurization member.SOLUTION: A local pressurization device 2 has a pressurization member 41X, and a driving part 45X. The pressurization member 41X has a front end exposed to a runner 107e communicating with a product part 107a of a mold 101, and is movable in a direction crossing a moving direction of a plunger 21. The driving part 45X imparts forward force to the pressurization member 41X. The pressurization member 41X is positioned at an initial position forward from a retreat limit when molten metal reaches the position of the pressurization member 41X, and is retreated from the initial position by being pushed by the molten metal.SELECTED DRAWING: Figure 1
