Abstract

The invention discloses a vertical parting arrangement casting system and process for crankshafts, and relates to the technical field of crankshaft casting. The vertical parting arrangement casting system comprises a transverse gate, three vertical gates connected to the lower portion of the transverse gate, pressing edges symmetrically connected to the peripheral sides of the vertical gates, sheets connected to the lower portions of the vertical gates, vertical cranks connected to one ends of the sheets and connected with the pressing edges, a sprue gate reversely connected to the lower portion of the pressing edge located in the middle of the three pressing edges in a lap joint mode, and transverse cranks connected to the two ends of the sprue gate. According to the vertical parting arrangement casting system and process, the vertical cranks are vertically placed, molten iron enters from the pressing edges and the sheets, the molten iron flow during molten iron entering is increased, and the vertical crank casting speed is increased; and molten iron impurities can be filtered out by arranging the sheets, upward molten iron pressure reduction is facilitated through the pressing edges, the casting speed is reduced, and vertical crank sand washing is conveniently reduced.

Description

technical field [0001] The invention belongs to the technical field of crankshaft pouring, and in particular relates to a pouring system and pouring process for crankshaft vertical split arrangement. Background technique [0002] The crankshaft is the most important component in the engine. It bears the force transmitted by the connecting rod and converts it into torque through the crankshaft output and drives other accessories on the engine to work. The crankshaft is affected by the centrifugal force of the rotating mass, the periodically changing gas inertial force and the reciprocating inertial force, so that the crankshaft is subjected to the bending torsional load. Therefore, the crankshaft is required to have sufficient strength and rigidity, and the surface of the journal needs to be wear-resistant, work evenly, and have good balance. [0003] However, the pouring efficiency of the existing crankshaft is relatively slow, and sand washing is easy to affect the pourin...
