DIE ASSEMBLY

摘要

CASE 4196 DIE ASSEMBLY A die assembly is comprised of vertically split upright support blocks formed with flat-surfaced recesses, and includes a plurality of rectilinear members formed with flat surfaces abutting the recess surfaces. The members include flat surfaces located opposite the abutting surfaces and defining a lower die cavity having an open upper end to receive molten metal for squeeze casting. The rectilinear and flat surface construction simplifies the fabrication and repair of the lower die members. The die assembly includes a guide member positioned above the lower die and formed with a through-passage communicating with the die cavity. The passage is formed with outwardly divergent upper and lower end sections. During the squeeze casting operation, an upper die is inserted into the guide member and cooperates with the lower end section to form a narrow cavity communicating with the die cavity. The narrow cavity acts to contain the initial spit-out of metal and allows it to solidify rapidly, thus forming a seal to prevent further molten metal spit-out from the lower die cavity during the squeeze casting operation.
