Embodiment Construction

[0030] Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:

[0031] Such as Figure 1~3 As shown, a new energy vehicle water-cooled motor casing manufacturing process is manufactured in the following steps,

[0032] (a) Install the cast sand core piece 1 into the die-casting mold, the sand core piece 1 is divided into an installation part 11 and a spiral part 12, and the installation part 11 is clamped and positioned in the groove of the die-casting mold;

[0033] (b) Put the aluminum ingot into the melting furnace, the aluminum ingot is AC4B or AC2B or AC3AM or AC4C or A357, the melting furnace is heated to 700 ~ 720 ℃ to melt the aluminum ingot into molten aluminum, and the air pump drives the aluminum liquid to flow from the pipe In the die-casting mold, the spiral part 12 of the sand core piece 1 is completely immersed in the molten aluminum, and the mounting part 11 is exposed from the molten aluminum, so...

Abstract

The invention relates to a new energy vehicle water-cooling motor shell manufacturing process and its structure. The water-cooling motor shell manufacturing process is reasonably designed and is capable of increasing the various performance parameters of the water-cooling motor shell. According to the invention, after eleven steps of processing and manufacturing referred to as from (a) to (k), the water-cooling motor shell is characterized by its stable and reliable structure, absence of casting defects and residual sand cores in spiral waterway and up-to-scratch hardness. Therefore, the service life time of the water-cooling motor shell is increased and the actual utilization need can be met.

Description

technical field [0001] The invention relates to the field of new energy vehicle motor casings, in particular to a manufacturing process and structure of a new energy vehicle water-cooled motor casing. Background technique [0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrate advanced technologies in vehicle power control and drive, and form vehicles with advanced technical principles, new technologies, and new structures. The new energy vehicles on the market now use motors as power drives. Due to the fast speed and high heat generation of the motors, water-cooling structures are generally used on the motor housing to cool down and dissipate heat. The traditional process of producing motor casings with water-cooled structures is to pour molten aluminum into a die-casting mold, which is pre-installed with a spiral sand core, and the die-casting machine works to die-cast the motor casing with a spiral water channel, an...
