CASTING DIE AND ALUMINUM CASTING METHOD

To provide a casting die capable of shorting a distance from a pouring gate to a second cavity terminal without causing casting defects.SOLUTION: A molten metal 12 is fed from a pouring gate 58 to a main runner 59 and is branched to a first runner 61 and a second runner 62 while along a conical face 57b of a conical part 57, and the molten metal passing through the first runner 61 is poured into a first cavity 53 and the molten metal passing through the second runner 62 is poured into a second cavity 54.EFFECT: The molten metal flows along the conical face, thus is not disturbed. The pouring gate and the main runner are provided between the first cavity and the second cavity, thus a distance from the pouring gate to the second cavity terminal is shortened.SELECTED DRAWING: Figure 5 【課題】鋳造欠陥を伴わないで、湯口から第２キャビティ末端までの距離を短くすることができる鋳造金型を提供する。【解決手段】溶湯１２は、湯口５８から主湯道５９に供給され、円錐部５７の円錐面５７ｂに沿いながら第１湯道６１と第２湯道６２に分流され、第１湯道６１を通る溶湯が第１キャビティ５３に注湯され、第２湯道６２を通る溶湯が第２キャビティ５４に注湯される。【効果】溶湯は円錐面に沿って流れるために、乱れない。第１キャビティと第２キャビティの間に湯口及び主湯道を設けたので、湯口から第２キャビティ末端までの距離が短くなる。【選択図】図５
