    摘要: In order to prevent casting with an abnormal hollow core having partially thin wall or filled in parts, a new method suitable for forming good hollow core stably and suitable for checking the hollowness of the moulded core before casting is proposed. This method comprises a step of providing a filling hole and an air inlet hole in a mould for core formation, a step of filling the mould with core sand with the air inlet hole in a closed state, a step of heating the mould and a step of sucking out unhardened sand through the filling hole with the air inlet hole in an open state. Unhardened sand is sucked out with the air flow from the air inlet hole to the filling hole, and the hollowness of the core is checked by measuring the pressure at the filling hole.

    摘要: In pouring molten metal in a die casting device wherein a shot sleeve for supplying molten metal in a die cast mold is substantially horizontally arranged, a guide means for conducting molten flow is obliquely removably inserted into said shot sleeve through an opening provided at a top portion of said shot sleeve so as to guide a flow of molten metal directly into a molten holding space provided at a forward end portion of said shot sleeve.
