Abstract

The invention discloses an integral sand core casting method for a spiral waterway of a new-energy automobile motor casing and a sand core structure. The integral sand core casting method comprises the steps of automatic mold closing and core injection molding. In the step of automatic mold closing, a core pulling mold, a bottom mold, a first mold closing and a second mold closing are closed automatically; a fourth mold cavity matched with the integral sand core of the spiral waterway is formed by a cylinder body of the core pulling mold, a first mold cavity located in the semi-circle groove of the bottom mold, a second mold cavity of the first mold closing, a third mold cavity of the second mold closing; and the fourth mold cavity comprises a sand inlet. In the step of core injection molding, ceramsite in a workbin is injected into the fourth mold cavity through the sand inlet; and the integral sand core of the spiral waterway is molded preliminarily in the fourth mold cavity. According to the integral sand core casting method for the spiral waterway of the new-energy automobile motor casing, by means of automatic mold closing, the fourth mold cavity matched with the integral sandcore of the spiral waterway is formed; then the ceramsite is injected into the fourth mold cavity, and the integral sand core of the spiral waterway is acquired in an integrally-molded manner; the molding operation of the integral sand core of the spiral waterway is simplified; and thus the molding rate of the sand core is improved, and the molding quality of the sand core is also improved.

Description

technical field [0001] The invention relates to the field of new energy automobile motor casings, in particular to a new energy automobile motor casing spiral water channel integral sand core casting method and a sand core structure. Background technique [0002] New energy vehicles refer to vehicles with advanced technical principles, new technologies and new structures that use unconventional vehicle fuels as power sources and integrate advanced technologies in vehicle power control and drive. The new energy vehicles on the market now use the motor as the power drive device. Due to the fast speed and high heat generation of the motor, a spiral water cooling channel is generally provided inside the motor housing to cool down and dissipate heat. Therefore, it is necessary to produce a motor housing with a water-cooled structure. [0003] The existing process for producing motor housings with water-cooling structures is as follows: pour molten aluminum into a die-casting mol...
