摘要： PROBLEM TO BE SOLVED: To realize a die casting die where, when a die casting die is cooled with cooling water, high water cooling effect can be obtained in a part having a high die surface temperature, and cooling water can be quickly dried in a part having a low die surface temperature.
SOLUTION: The cavity face 12 of the die casting die 2 is covered with a hydrophilic surface treatment layer 28, thus a Leidenfrost phenomenon is prevented, and a water film of cooling water 22 widely spreading to the surface treatment layer 28 can be formed. The cavity face 12 can be uniformly cooled. By covering a parting plane 18 with a hydrophobic surface treatment layer 24, the cooling water 22 is repelled at the parting plane 18, thus the time taken for drying can be shortened. Since the time required for the cooling and the time required for the drying in the die casting die 2 can be shortened, a precise die-cast product can be mass-produced in a short period of time.

摘要： PROBLEM TO BE SOLVED: To provide a foreign matter removal device for a molten metal where the same passage of a molten metal is changed into a molten metal discharge passage or a molten metal suction passage with a simple constitution, and without back-washing foreign matters captured by a filter, a molten metal freed from foreign matter can be discharged. SOLUTION: A molten metal 2 in a vessel 3 is discharged via a molten metal passage 5, and further, the molten metal is sucked into the vessel 3. The edge part 5b of the molten metal passage is provided with a filter 6 made of a material having a specific gravity lower than that of the molten metal in a floating state. Upon the suction of the molten metal, the filter 6 is depressed, and the molten metal does not pass through the filter 6 and passes through a gap made between a passage port and the filter 6 so as to flow into a storage vessel 3. Upon the discharge of the molten metal, the filter 6 covers the passage port of the edge part 5b, and the molten metal passes through the filter 6 and is discharged. In this way, only upon the discharge of the molten metal, foreign matters are captured by the filter 6, and the foreign matter sticks to the lower face side of the filter 6. Thus, the phenomenon that the foreign matter at the upper face side of the filter is back-washed and is intruded into the molten metal upon the discharge of the molten metal does not occur, and a clean molten metal can be discharged.
