Abstract

PURPOSE:To improve the quality of a formed product by arranging a vacuum sub-vent separately from a vacuum main vent, shutting the main vent at the time of coming of molten metal and next, maintaining reduced pressure in a cavity through the sub-vent. CONSTITUTION:A recessed part 14 for forming the cavity and the vacuum main vent 15 are arranged in the movable die 4 and also the vacuum sub-vent 19 is arranged and an overflow part 20 and a vacuum port 17 are communicated. Further, shut-out pins 23, 24 are set in first and a second penetrating holes 21, 22, respectively. At the time of pouring the molten metal 30 into a sleeve 5 at low speed, air exhausts through a vent 18 and the first pin 23 shakes a shaking arm 27 and the second pin 24 shuts the main vent 15. After that, the sub-vent 19 continues vacuum suction through a vacuum device 16 till completing filling-up of the molten metal 30. As the reducing pressure for the vacuum is always maintained under good condition, the quality of the formed product is improved.
