Description

Technical Field

[0001] The utility model relates to an injection mold, in particular to a stator frame injection mold. Background Art

[0002] The stator is a fixed part of the machine. It is composed of three parts: stator core, stator winding and frame. The main function of the stator is to generate a rotating magnetic field, while the main function of the rotor is to be cut by magnetic lines of force in the rotating magnetic field to generate (output) current. The stator is usually composed of an iron core, a coil, a skeleton, leads, tension springs, etc. There are two ways to connect the stator, one is a 4-wire type, in which the rotor is connected in series between two stator windings, and the other is a 2-wire type, in which the two stator windings are connected in series with the rotor and then connected in series with the rotor. The two wiring methods are different but can be used interchangeably. There are two ways to lead in: one is soft wire lead-out; the other is lead-out by the connector on the skeleton. The skeleton must be retained during this winding. In the prior art, injection molds have been widely used in the processing of stators in motor frames. However, most of the existing stator frame injection molds are integrated. After the stator frame is injection-molded, it is necessary to use an ejection mechanism to eject the stator frame from the mold. Since the stator frame is relatively soft after the injection molding is completed, it is easy to cause the stator frame to deform during ejection, resulting in defective products. Summary of the invention

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model proposes a stator frame injection mold, which effectively solves the problem that most of the stator frame injection molds on the market are integrated. After the stator frame is injection molded, it is necessary to use an ejection mechanism to eject the stator frame from the mold. Since the stator frame is relatively soft after the injection molding is completed, it is easy to cause the stator frame to deform during ejection, resulting in defective products.

[0005] Furthermore, the decomposable mold shell is fixedly connected to the hydraulic telescopic column, and the hydraulic telescopic column is fixedly connected to the base through a mounting seat.

[0010] Furthermore, the hydraulic telescopic columns are provided in three groups, and the decomposable mold shells are provided in three groups.

[0011] The beneficial effects achieved by the utility model using the above technical solution are as follows:

[0012] The utility model provides a stator frame injection mold. After injection molding, the second hydraulic lifting column drives the upper mold core of the upper mold shell to be pulled out from the stator frame of the lower mold groove, and at the same time controls the hydraulic telescopic column to drive the decomposition mold shell to open outward, so as to take out the stator frame after injection molding to avoid extrusion deformation.
