Casting mold of motor housing of new energy large energy storage fly wheel and process method thereof

Abstract

The invention discloses a casting mold of a motor housing of a new energy large energy storage fly wheel and a process method thereof. The casting mold comprises an integrated fly wheel housing casting mold and a split flywheel housing casting mold; the mold is a resin sand mold which is core-pulled and formed by an aluminum mold; an outer mold adopts at least 30 fan-shaped modules which are tightly spliced to form the round barrel-shaped outer mold; the angles of central angles corresponding to the fan-shaped modules are equally divided angles of the central angles, the resin sand core mold and a base are positioned and assembled in an inner hole of the barrel by means of hoisting equipment; the split flywheel housing comprises a barrel and a bottom plate, and the barrel and the bottom plate are perpendicularly formed mutually by means of robot welding, and the motor housing is manufactured by means of an integrated casting mold process method and a split casting mold process method.The flywheel housing disclosed by the invention adopts an aluminum-silicon alloy and American standard A356, and is produced by means of a resin sand molding low-pressure pouring process, so that thecasting mold is high in production efficiency, low in cost, stable and reliable in product quality and high in rate of finished products.

Description

technical field [0001] The invention relates to the field of casting technical equipment for large-scale energy storage flywheel motor casings, in particular to a new energy large-scale energy storage flywheel motor casing casting mold and a process method thereof. Background technique [0002] With the rapid increase in the scale of new energy power generation, the contradiction between the power grid and new energy is becoming more and more prominent, and the demand for energy storage is more urgent; the flywheel energy storage system is an energy storage device for electromechanical energy conversion of physical energy storage. A typical flywheel energy storage system consists of five main components: the flywheel body, bearings, motor / generator, power converter, and vacuum chamber. [0003] In the prior art, the flywheel housing of Rotnick, a subsidiary of the Boeing Company of the United States, which specializes in kinetic energy storage devices, is 1.2 meters high and...
