Problems solved by technology

[0002] As we all know, the frame is one of the main components of the motor. The quality of the frame has a great impact on the quality of the motor. The existing aluminum frame of the motor has a built-in water-cooled copper tube. During casting, a water-cooled tube is installed in the mold. The copper tube is poured to obtain a water-cooled aluminum frame. The aluminum frame of the motor produced by this method has poor strength and is prone to cracking, etc., resulting in a short service life of the aluminum frame of the motor and greatly increasing the cost of reproduction or maintenance.

Abstract

The invention discloses a casting method of a water-cooling aluminum engine base embedded with a support. The method is characterized by comprising the following steps: preheating an iron support and a die, wherein, the iron support is wound with a cooling copper pipe; installing and positioning the iron support wound with a cooling copper pipe in the die; making a sprue; casting; demolding; and cleaning a casting head. By adopting the casting method, the iron support is taken as a skeleton to successfully carry out inlay casting on the water-cooling copper pipe aluminum engine base, the overall mechanical strength of the engine base is ensured, and the purpose for reducing the weight of the engine base is achieved.
