Description

Technical Field

[0001] This utility model relates to the field of motor mold technology, specifically a motor core mold for rotor rotation. Background Technology

[0002] An electric motor is a device that converts electrical energy into mechanical energy. It mainly consists of a stator and a rotor. The direction of motion of a current-carrying conductor in a magnetic field depends on the direction of the current and the direction of the magnetic field lines. The working principle of an electric motor is that the magnetic field exerts a force on the current, causing the motor to rotate.

[0003] In the process of motor manufacturing, molds are needed to make iron cores. Most of the molds used for motor iron core production are directly stamped and formed, resulting in iron cores with inconsistent thicknesses, which affects the quality of iron core manufacturing.

[0004] There is an urgent need for a rotor-rotor-rotor motor core mold to address the technical deficiencies mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a rotor-rotating motor core mold to solve the problem of uneven processing thickness mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rotor-rotating motor core mold, comprising a processing table, a lower mold mounted on the top of the processing table, an upper mold disposed above the lower mold, a support frame fixedly connected to the top of the processing table, a hydraulic cylinder mounted on the top of the support frame, the output end of the hydraulic cylinder connected to the top of the upper mold, a fixed frame mounted on the left side of the lower mold, a servo motor mounted on the top of the fixed frame, a first synchronous roller movably connected inside the fixed frame, a first mold cavity movably disposed on the left side inside the lower mold, a second mold cavity movably connected on the right side inside the lower mold, a second synchronous roller mounted at the bottom of both the first and second mold cavities, a synchronous track mounted outside the first and second synchronous rollers, a first mold head mounted on the left side of the bottom of the upper mold, and a second mold head mounted on the right side of the bottom of the upper mold.

[0009] Preferably, mounting plates are provided at both ends of the first mold cavity and the second mold cavity, and mounting bolts are provided on the mounting plates, which are embedded in the interior of the lower mold.

[0010] Preferably, the lower mold has six sets of positioning holes inside, and the bottom of the upper mold is fixedly connected to six sets of positioning pins, with the positioning pins embedded inside the positioning holes.

[0011] Preferably, the lower mold has a pre-drilled hole inside, and the bottom pad of the upper mold is fixedly connected to a limiting post, which can be embedded inside the pre-drilled hole.

[0012] Preferably, the upper mold and the lower mold are of the same size, and the first mold head is positioned above the first mold cavity.

[0013] Preferably, the lower mold has a bearing installed inside, and the first and second synchronous rollers are installed inside the bearing.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the rotor-rotating motor core mold not only realizes the function of enhancing processing uniformity and facilitating stable positioning, but also realizes the function of facilitating disassembly and assembly.

[0015] (1) By setting up a lower mold, an upper mold, a servo motor, a fixed frame, a synchronous track, a first synchronous wheel and a second synchronous wheel, when the hydraulic cylinder pushes the upper mold to move downward, the first mold head and the second mold head on the upper mold can be inserted into the first mold cavity and the second mold cavity. During the pressing process, the servo motor drives the first synchronous wheel to rotate, and the synchronous track on the first synchronous wheel drives the second synchronous wheel to rotate. The second synchronous wheel can drive the first mold cavity and the second mold cavity to rotate to achieve rotary processing. Rotary processing can make the thickness of the stamped iron core uniform, thereby enhancing the processing uniformity and high quality.

[0016] (2) By setting up positioning holes, reserved holes, limit pins and positioning pins, the hydraulic cylinder pushes the upper mold to move downward, the upper mold docks with the lower mold, and the limit pins and positioning pins on the upper mold can be inserted into the positioning holes and reserved holes of the lower mold to achieve positioning. This structure realizes the function of easy and stable positioning.

[0017] (3) By providing a first mold cavity, mounting bolts, a second mold cavity and mounting plate, the first mold cavity and the second mold cavity facilitate the processing of the electrode core. The first mold cavity and the second mold cavity are installed inside the lower mold. During installation, the first mold cavity and the second mold cavity are first installed in the designated position, and then the mounting plate and the corresponding installation are installed and fixed with mounting bolts. Therefore, the first mold cavity and the second mold cavity can be disassembled and cleaned. This structure realizes the function of easy disassembly and cleaning. Attached Figure Description
