Low-pressure casting mold for motor water-cooled housing

Abstract

The invention belongs to the technical field of molds, and relates to a low-pressure casting mold for a water-cooled casing of a motor. A central cavity formed by a base plate is positioned at the bottom of an annular cylinder surrounded by more than three moving modules, and the upper part is fixed by a central column fixing plate. The core column of the casting mold, an annular mold cavity is formed between the side surface of the core column of the casting mold, the inner surface of the annular cylinder and the lower surface of the fixing plate of the core column, and the annular mold cavity is formed between the core column of the casting mold and the upper surface of the base plate and the inner surface of the annular cylinder. The lower mold cavity is connected with the cavity, the annular mold cavity is suspended with a spiral water channel mud core, the bottom of the core column of the casting mold is positioned with the middle mud core of the casting mold, and the middle convex column of the lower bottom of the mud core of the casting mold is sleeved with an insert ring. The base plate is provided with more than two casting liquid inlets that communicate with the lower cavity, and the inner wall of the moving module is provided with grooves for forming the motor housing junction box, the mounting seat, and the spiral water channel inlet and outlet. The advantages are: production cost Low, good thermal conductivity and heat dissipation performance, low failure rate, stable product quality.

Description

Technical field [0001] The invention belongs to the technical field of molds, and particularly refers to a low-pressure casting mold for a motor water-cooled shell. Background technique [0002] With the rapid development of electric vehicles, the number of motors used in automobiles has also increased. The motors of passenger electric vehicles generate large amounts of heat due to their high power. Good heat dissipation has become the key to passenger electric vehicles. Cooling methods include fan cooling and spiral water channel or water jacket cooling. The spiral water channel or water jacket is mostly welded to the outer surface of the motor shell to connect the spiral water channel or water jacket. The disadvantage is that the production process is complicated, the production cost is high, and the failure rate is high. High, poor heat dissipation. Summary of the invention [0003] The purpose of the present invention is to provide a low-pressure casting mold with low product...

[0002] With the rapid development of electric vehicles, the number of motors used in automobiles has also increased. The motors of passenger electric vehicles generate a lot of heat due to their high power. Good heat dissipation has become the key to motors used in passenger electric vehicles. The current The cooling methods include fan cooling and spiral water channel or water jacket cooling. Most of the spiral water channels or water jackets are welded on the outer surface of the motor shell to connect the spiral water channel or water jacket. The disadvantages are complex production process, high production cost, and failure rate. High, poor cooling effect
