Detailed Description

The following embodiments are only intended to illustrate the present invention in detail, and do not limit the scope of the present invention in any way. The unit module components, structures, mechanisms, sensors and other devices referred to in the following examples are all conventional and commercially available products unless otherwise specified.

Example (b): as shown in fig. 1-3, a motor casing casting mold comprises an upper moving plate 10 and a lower moving plate 11 which can reciprocate along a vertical direction, wherein three upper modules 12 are arranged on the lower surface of the upper moving plate 10, three lower modules 13 are arranged on the upper surface of the lower moving plate 11, three middle modules 14 which can reciprocate along a horizontal direction are arranged between the upper moving plate 10 and the lower moving plate 11, the upper parts of the middle modules 14 are connected with the upper modules 12 in a sliding manner, the lower parts of the middle modules 14 are connected with lower molds 13 in a sliding manner, first grooves 18 corresponding to heat dissipation fins 27 are arranged on the inner sides of the upper modules 12, the middle modules 14 and the lower modules 13, and when the molds are closed, the upper moving plate 10, the lower moving plate 11, the upper modules 12, the middle modules 14 and the lower modules 13 enclose a molding cavity 15, and sand core modules 16; the two ends of the middle module 14 are provided with second grooves 17 corresponding to the connecting blocks 26, and the middle module 14 can move along the radial direction of the forming cavity 15 under the driving of the power mechanism.

In this embodiment, in order to fix sand core mold 16, positioning block 29 is provided on lower moving plate 11, and positioning groove is provided at the bottom end of sand core mold 16.

In this embodiment, in order to reduce the subsequent processes of the motor housing, the forming cavity 15 includes a main cavity 19 and an auxiliary cavity 20 which are communicated, a clamping groove 21 is provided on the upper module 12 and the lower module 13, a mud seat mold 22 is clamped in the clamping groove 21, and the mud seat mold 22 is located in the auxiliary cavity 20.
