Abstract

The invention discloses a height-limit feeding head structure for a bearing seat. A casting sand core of the bearing seat is in a one-template and four-piece layout structure. Two first dead heads and a plurality of second dead heads are arranged, and the first dead heads are arranged between sand core cavities of two adjacent bearing seats, so that a ductile iron liquid flows into a water inlet channel through a sprue gate, and then flows into the cavities of the four bearing seats through the water inlet channel; the first dead heads perform feeding on bottom plates of the bearing seats, and the second dead heads are arranged in windows of the bearing seat cavities and perform the feeding on the tops of the bearing seats. Through the scientific selection, according to the structural characteristics of parts that the top is thick and large and the bottom is thin-walled and is not processed, the feeding heads at the top are arranged in the windows at two oblique sides, accordingly, the amount of the feeding liquid can be effectively ensured, the shrinkage porosity defect can be prevented; the densification of a microstructure is ensured and further the dimensional accuracy of castings is ensured.

Description

technical field [0001] The invention relates to the technical field of automobile parts manufacturing, more specifically, it relates to a height-limiting feeding process of a bearing seat. Background technique [0002] The support seat is a part of the automobile saddle. Its structure is not complicated, but it has a partially thick structure and the bottom of the thick part is thin-walled. For example, when it is manufactured on a casting production line, the sand box height of the production line is uniform. It is 300mm, and the top of the support seat is thick, and the thick part is at the highest position during pouring. Due to the limitation of the height of the static pressure molding line flask, it is not possible to add a feeder on it. Therefore, limited by the height of the flask, It is not possible to add feeders on the top of thick and large parts, and other technological methods need to be considered to ensure the dimensional accuracy and casting quality of casti...
