[0002]
In the process of forming a new energy motor shell, the inventor found the following problem: the motor shell corresponds to the installation hole for installing the motor shaft, and the strength, hardness, wear resistance and other performance requirements of this hole are high, and the molten liquid die-casting Forming, the performance cannot meet the requirements of use, and in the existing technology, the performance of the mounting hole is improved by adding a 40Cr annular reinforcement; at present, the processing method of clamping the reinforcement to the motor housing after processing is most commonly used , but the fixing effect of this method is not ideal. First, in a long-term vibrating working environment, the reinforcement is easy to fall off from the mounting hole due to the vibration inertia; secondly, when the reinforcement is installed in the mounting hole , since the mounting hole and the reinforcing piece need an interference fit, the reinforcing piece with better performance will easily cause the deformation of the motor shell during the installation process, resulting in damage to the motor shell

The invention provides a moving mold mechanism for forming a new energy motor shell. The moving mold mechanism comprises a moving mold core plate provided with a forming part, and a positioning pin extending out of the forming part, wherein an insert is embedded in a motor shell, and is coated with a molten liquid so as to form the whole motor shell, before forming, the insert is transferred to the positioning pin, the forming part comprises a first forming insert, the first forming insert is detachably connected to the moving mold core plate, the positioning pin penetrates upwards from the bottom of the moving mold core plate in the direction of the center line perpendicular to the first forming insert and extends out of the first forming insert, and the top end of the positioning pin bears the insert. The moving mold mechanism is convenient to use and simple in structure.
