Abstract

Use1 in the manufacture of casting molds with tunnel sprues The essence of the invention is that the mold contains a forming plate 3 with sockets 4, diverting channels 5, made in the form of grooves in the forming plate 3 with a longitudinal section in the shape of a triangle, and inlet tunnel sprues with axes located perpendicular to the longitudinal axis of the diverting channel 5. In this case, the angle between the larger side opposite the tunnel inlet gating channel and the plane of the connector is made not exceeding the angle between the upper generator final year at tunnellnyh runner 6 and the same plane, and the latter is chosen not less than 45 ° 5 il A-A
