Abstract

The invention discloses a casting method of an integrated water-cooled motor casing of a prefabricated spiral channel. The casting method comprises the steps of providing the prefabricated spiral channel: fixing the prefabricated spiral channel to a casting die; introducing a cooling medium to the spiral channel; and forming by adopting a low-pressure casting process so as to obtain the high-quality integrated water-cooled motor casing. According to the casting method, the cooling medium is introduced into the circulating channel during casting, so that a pipeline of the prefabricated spiral channel can be prevented from being softened and deformed and even molten by alloy liquid during casting, an inner cavity of the pipeline is not damaged, and the production process and the product reliability are guaranteed. According to the casting method, the prefabricated spiral channel is made of materials which are the same as or close to that of the motor casing, so that the pollution of thechannel materials on the base material of the motor casing can be avoided or reduced when the waste motor casing is recycled and melted.

Description

technical field [0001] The invention belongs to the technical field of manufacturing new energy motor housings, and in particular relates to a casting method for an integral water-cooled motor housing of a prefabricated spiral water channel. Background technique [0002] combine figure 1 As shown, the motor casing 11 used to cool the electric drive on the new energy vehicle, its built-in water channel 12 is not allowed to have leakage, cracks, etc. The top-down feeding effect makes casting more difficult. [0003] At present, there are two main types of motor housings on the market: [0004] One type is the split water-cooled circulating motor housing. The inner sleeve and the outer sleeve are mainly assembled by gravity casting, processing, thermal sleeve, welding and other processes. Since this method has many production processes, the production process has certain instability. The investment is large, and gravity casting is difficult to have good compactness; and afte...
