Title: Pressure casting device
Inventor: UOZUMI MINORU
IPC: B22D18/08
Filed: 1980-07-09
Abstract: PURPOSE: To achieve the pressure charging of molten metal efficiently by holding the head of a molten metal supply passage to a metallic mold in a constant level by the internal pressure of a heat-insulation furnace and by performing the pressure charging from the molten metal supply passage to the metallic mold by means of a pump.  
     CONSTITUTION: Molten metal A reserved in the soaking pit 2 is compressed by the pressure of a pressure space 8 to maintain the bath surface of a molten metal supply channel 10 at a constant height. The molten metal surface in the supply channel 10 is detected with a molten metal surface detector 11. A gas supply valve 5 and an evacuation valve 7 are operated to open or close with a valve regulator 13. When the molten metal surface is lowered, the pressure gas is supplied from a pressure source 6 to a pressurized space 8. When the molten metal surface is elevated, the pressure gas in a pressurized space 8 is released into the atmosphere to keep the molten metal surface at a constant level. Under these conditions, an electromagnetic pump 17 permits to fill the mold with molten metal A. In this case, the molten metal surface in the supply channel 10 is lowered, but the controlling operations of the molten metal surface detector and the valve regulator 13 permit to maintain the molten metal surface in the supply channel 10 at a constant level. On the other hand, molten metal A is supplied from a molten metal supply channel 9 suitably.
