Embodiment 1
[0022] A 200KW energy vehicle integrated water-cooled motor casing, designed with 9 turns of spiral water channel, which is used in the public transportation industry after assembly. The motor casing is required to have good comprehensive performance such as rapid heat dissipation, high strength, good toughness, and light weight Ensure safety and efficiency. The main processes used are:
[0023] The first step is to use the hot core box coated sand core to make the nine-turn spiral water channel core. Among them, 17 positioning core heads are set on the nine-turn spiral water channel core, and the 17 positioning core heads are integrated with the nine-turn spiral water channel core. , 17 positioning core heads match the positioning holes on the mold of the water-cooled motor casing; the method of making the coated sand core is to use 50-100 mesh thermosetting phenolic resin coated sand, the gas production is 11ml / g, and the bending strength at room temperature is 7MPa. The ho...
