Abstract

The invention discloses a cylinder body full core assembly pouring system and relates to the technical field of casting of castings. The system comprises a transverse pouring gate, a sprue and a slowflow filtering cavity. Slow flow channels are symmetrically connected to the discharging side of the bottom of the sprue. Discharging openings of the slow flow channels are connected with the transverse pouring gate through the slow flow filtering cavity. A sprue nest is arranged at the bottom end of the sprue. The cylinder body full core assembly pouring system has a good metal liquid filtering function, and is provided with a reasonable slag storing cavity structure, the cross section changes smoothly, and metal liquid is guided smoothly.

Description

technical field [0001] The invention belongs to the technical field of casting castings, and in particular relates to a pouring system for a full set of cylinder cores. Background technique [0002] Automobile companies continue to shorten the product development cycle, and the core castings such as engine cylinder block adopt mold opening and trial production within 60-90 days, which is difficult to meet the needs of prototypes for product development process verification. The use of 3D printing manufacturing technology to directly print sand cores, and then assemble the cores for pouring, and carry out moldless rapid manufacturing of cylinder castings can greatly shorten the trial production cycle of castings. [0003] Rapid prototyping is a small-batch production, which requires high molding pass rate but not high casting process yield rate. In the design of the casting gating system, it is necessary to meet the requirements of the filling process to the greatest extent,...
