Embodiment Construction
[0019] In order to further illustrate the purpose, features and effects of the present invention, the following details are described in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, it is the lost foam casting method of the integrated spiral channel aluminum alloy motor shell of the present invention, including:
[0021] Step 1. Design of the mold structure of the white mold of the motor shell: specifically, in combination with the structural characteristics of the product, the inner cavity of the motor shell of the spiral channel and the bottom end cover are designed as one; the purpose is to reduce a foam bond and ensure the front cover and the inner cavity coaxiality accuracy.
[0022] Step 2, pre-foaming and mold forming: specifically, pre-foaming with large copolymerized foam beads and small copolymerized foam beads at the same time, controlling the steam source pressure 0.05--0.08Mpa, adjusting the electric contact pressure gauge (0.05...

Abstract
The invention discloses a casting method for an integrated spiral water channel aluminum alloy motor casing evanescent mold. The casting method can achieve the purpose of casting the integrated spiral water-cooling motor casing evanescent mold which is large in spiral water channel diameter, large in number of spiral rings and small in spiral water channel cross section. The production efficiency is effectively improved, the product precision is high, the inner cavity draft angle is very small, the machining allowance is small, the cast wall reaches 5 mm, and the light manufacturing process is achieved through effective integrated water-cooling motor shell casting. Meanwhile, the service life of the mold is long, the production takt is greatly shortened, and the automation degree is high.
Description
technical field [0001] The invention relates to the field of casting technology, in particular to a lost foam casting method for an integrated spiral channel aluminum alloy motor casing. Background technique [0002] With the continuous over-exploitation of non-renewable energy and the damage to the earth's atmospheric ecology, clean energy vehicles have become a new means of transportation in this century. As for the core auto parts—the motor, the spiral water channel forming of the motor casing has an extremely important influence on the thermal cycle of the whole motor, and the water channel structure is very complicated, and it cannot be processed in the closed clamp cavity, so the clamp The precision of the cavity is very accurate, and the surface cleanliness is very high. The integrated water-cooled shell casting is currently facing the difficulty of casting and molding, and the application that cannot achieve mass production. [0003] At present, the metal gravity ca...
