It is a kind of for improve product quality and with die cavity lug boss die casting
Technical field
The present invention relates to die casting mold field, more particularly to it is a kind of for improve product quality and with die cavity protrusion
The die casting in portion.
Background technology
Electric machine casing is usually the important component of motor, and motor itself can send out larger heat when motor rotates, so
The thickness of electric machine casing is extremely important to motor, but electric machine casing generally selects die casting and produced, the material of itself
Matter can not change, in order to ensure electric machine casing is molded, it will usually which electric machine casing is designed to thicker structure, thicker electricity
The heat that casing body can not merely generate motor carries out rapid drainage and also substantially increases production cost, in order to save production
Material, while making to facilitate electric machine casing to be molded while the thickness reduction of shell, design a kind of new structure of cast die right and wrong
Often it is necessary to.
