Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a forming mold for the shell of a stepping linear motor. Background Technique

[0002] An electric motor refers to an electromagnetic device that realizes the conversion or transmission of electrical energy based on the law of electromagnetic induction.

[0003] The patent with the publication number of CN219273770U discloses a production and processing mold for an electric motor shell, including a lower mold; a support column is fixedly connected to the bottom of the lower mold, an upper mold is arranged at the top of the lower mold, a pouring port is opened at the top of the upper mold, and a demolding component is arranged on one side of the lower mold. The demolding component includes a connecting block; by starting the rotating motor, the rotating motor drives the first gear arranged at the bottom to rotate, the first gear drives the transmission belt to rotate, and the transmission belt drives the second gear at the other end to rotate. Since a thread is arranged on the inner wall of the second gear, the rotation of the second gear will drive the lead screw to move upward. At the same time, when the lead screw moves upward, it will drive the push plate and the bottom plate at the top to move upward, and push the cooled electric motor shell at the top of the bottom plate upward until the electric motor shell is pushed out of the inner wall of the lower mold, so as to facilitate the demolding of the electric motor shell and solve the problem that the mold of the electric motor shell is not easy to demold.

[0004] The above patent uses a motor to take out the high-temperature shell after casting from the lower mold. In actual use, the upper mold and the lower mold need to be accurately and quickly connected before casting. Ordinary factories rely on the operating experience of workers and are prone to errors. In addition, after connection, ordinary casting molds only rely on the gravity of the top mold to connect with the bottom mold. Once the production personnel touch the shell of the top mold during the forming process, it is extremely easy to cause the shell of the stepping linear motor during the forming process to be skewed, affecting the final quality of the product.

A top mold 3 is movably connected to the top of the bottom mold 2. Connection components 4 for extrusion and limitation are fixedly connected to both sides of the surface of the top mold 3. The connection component 4 includes a top plate 41 fixedly connected to the surface of the top mold 3. Bottom blocks 42 are fixedly connected to both sides of the surface of the bottom mold 2. Dovetail grooves 43 are formed on both sides of the surface of the bottom block 42. A dovetail track block 44 is movably connected to one side of the inner wall of the dovetail groove 43. A limit sleeve 45 is fixedly connected to one side of the surface of the dovetail track block 44. An elastic sheet 46 is fixedly connected to the top of the inner wall of the limit sleeve 45.

Lifting rings 6 are fixedly connected to both sides of the top of the top mold 3. Anti-slip bumps are provided on the surface of the lifting ring 6. By using the setting of the connection component 4, the device can be limited by the limit sleeve 45 through the top plate 41 and the bottom block 42 at the same time, and the top plate 41 is pressed and limited by the elastic sheet 46, so that the bottom of the top mold 3 can firmly fit with the top of the bottom mold 2, effectively avoiding position changes caused by simple touch, and solving the problem that once the production personnel touch the housing of the top mold during the forming process, it is extremely easy to cause the housing of the stepping linear motor during the forming process to be skewed, affecting the final quality of the product.

[0024] Example 2, the main difference from Example 1 is: a forming die for the housing of a stepping linear motor. The guiding mechanism 5 includes an adapter plate 51 fixedly connected to the top die 3. The surface of the adapter plate 51 is provided with reinforcing ribs. The bottom of the adapter plate 51 is fixedly connected with a guiding rod 52. The bottom end of the guiding rod 52 is polished smoothly.
