BORE BRIDGE COOLING PASSAGE |
摘要 |
A tool and a method of using the tool are provided for forming an engine component. The engine has a block defining a first cylinder and a second cylinder spaced apart by a bore bridge. The bore bridge defines a first cooling passage spaced apart from a deck face and extending transversely, and a second cooling passage positioned between the first passage and the deck face and extending transversely. The first and second passages are formed by a casting skin. In forming the engine component, a die is provided that defines a locator recess and at least one core. An insert is positioned into the recess on the die. The insert has a cast shell surrounding a lost core. The component is die cast with the die and the insert to form a cooling jacket. The insert is adapted to form the cooling passages for the bore bridge. |

1. A tool for forming an engine component comprising:
a die having a support member defining first and second locator recesses positioned between first and second cores adapted to form a cylinder cooling jacket; and an insert having a lost core generally encapsulated by a cast shell, the insert having first and second locator protrusions sized to be received by the first and second locator recesses respectively, the insert adapted to form a cooling passage for a bore bridge of the engine component between adjacent cylinders. |
