Abstract
PURPOSE: To suppress the outflow of impurities on the top surface of molten metal and improve quality by providing a valve opening and closing the runner communicating part above a lower sleeve in a method of packing the molten metal into cavities by the upward movement of a lower plunger.
CONSTITUTION: Molten metal M is teemed through a sprue 7 into a sleeve 6, and flows into a sleeve 4 above a plunger 13, where it is stored. The sprue 7 is closed and the boundary part is closed by moving a control valve 11 downward and when the plunger 13 is moved upward, the metal M ascends and impurities M3 contact a ceiling 5a, then part of a solidified film M2 contacts the inner side of the valve 11. Next, the valve 11 is moved upward to the prescribed height to form an opening in the boundary part. When the ascending of the plunger 13 is continued, the solidified film in the opening part is broken and the molten metal M packs the cavities through a runner 10. The floating impurities M3 in the upper part of the metal M of this time are held in the lower part of the valve 11, and are prevented from flowing out into the runner 10, thus their inclusion into the packed molten metal is obviated.
