Description

Technical Field

[0001] The utility model belongs to the technical field of motor processing, and more specifically relates to a production mold for a motor shell. Background Art

[0002] When using the production mold in the process of producing motors, the molten molten iron is directly poured into the interior of the production mold body. After the molten iron cools down, the extrusion block is manually taken out of the interior of the production mold body through the connecting frame. In this way, the motor housing can be taken out of the interior of the production mold body, so that the motor housing can be produced well.

[0003] The inventors have found in their daily work that there are still at least the following problems in the processing of motor housing components: the motor housing produced by using a production mold is cast by molten iron, and then the formed motor housing can be taken out of the production mold body after the extrusion block is manually taken out of the interior of the production mold body. However, in actual use, because the motor housing is cast by molten iron, the formed motor housing is tightly stuck in the interior of the production mold body, and it is rather troublesome to take the formed motor housing out of the production mold body, which will affect the production efficiency of the motor housing to a certain extent. Utility Model Content

Positioning holes 807 are opened at both ends of the surface of the positioning plate 805. The inner wall of the positioning hole 807 is slidably connected to the inner wall of the positioning rod 806. When the production mold body 1 is turned upside down, the positioning rod 806 is inserted into the inner wall of the positioning hole 807 after passing through the support rod 802, so as to well control the round rod 801 to rotate on the surface of the support rod 802.

After the molten iron cools down, manually take out the extrusion block 2 from the interior of the production mold body 1 through the connecting frame 3, so that the motor shell can be taken out from the interior of the production mold body 1, so that the motor shell can be well produced. When using the extrusion device 7, manually control the limit bar 707 to slide inside the rectangular frame 705, so that the limit bar 707 is away from the connecting plate 703, because the rectangular frame 705 is longer than the production mold body 1, so that the limit bar 707 is away from the production mold body 1, so that the extrusion rod 702 can be inserted into the interior of the production mold body 1, and then manually hold the handle 704, and then extrude the formed motor shell in the direction close to the production mold body 1, so that the motor shell is well squeezed out of the interior of the production mold body 1, and then The motor housing can be easily taken out of the production mold body 1. When the extrusion device 7 is not in use, the second spring 709 is used to squeeze the limit bar 707 toward the direction close to the connecting plate 703, thereby well limiting the limit bar 707 inside the slide rail 708, and thus well limiting the extrusion rod 702 to the bottom of the production mold body 1.
