Abstract

A die-casting die for motor casings comprises a moving die set (1), a fixed die set (2), a forming part, and a core pulling mechanism, and is characterized in that the forming part is mounted on the moving die set (1) and the fixed die set (2). A die guide mechanism is arranged on the moving die set (1) and the fixed die set (2). Five side cores are mounted on five side sliders respectively. Each side slider matches with a corresponding T-shaped guide slide (10) on a moving die (3) and capable of sliding in the slide. The core pulling mechanism pulls out the cores through an angle guide pin. A wedge (13) assists in locking or loosening the core pulling mechanism. Finished products made by the die-casting die are high in size precision, stable in quality, excellent in appearance quality and high in process yield. In addition, the die-casting die is low in cost and convenient to mechanically operate and automatically control.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a motor casing die-casting mold. Background technique [0002] The motor casing is an important part of the motor, and the motor stator and the high-speed rotating rotor are installed inside the casing. Therefore, dimensional accuracy and mechanical properties determine the quality of the product. [0003] Usually the motor housing is produced by gravity casting. Gravity casting requires manual pouring. Factors such as the working temperature of the mold, the casting temperature of the alloy liquid, the casting speed, and the residence time of the casting in the mold are difficult to control in actual production. [0004] Die casting refers to a method in which molten metal fills the cavity at high speed under pressure to form a casting. It has the following characteristics: 1. High production efficiency; 2. Good forming performance of castings, high dimensional accuracy, high...
