SPRUE STRUCTURE FOR LOW-PRESSURE DIE CASTING DEVICE AND LOW-PRESSURE DIE CASTING DEVICE HAVING SAID SPRUE

Document Type and Number:

WIPO Patent Application WO/2016/132503

Kind Code:

A1

Abstract:

A sprue 1 for a low-pressure die casting device is provided with, as is shown in FIG. 1: a stalk connection part 11 for connecting to a stalk; a melt reservoir 12; and a cavity connection part 13 for connecting to the cavity. The melt reservoir 12 has a shape such that the length of the perimeter of the melt reservoir 12 at a cross-section in a direction perpendicular to the direction of flow of the melt gradually lengthens moving toward the cavity connection part 13 and the area of that cross-section is constant.
