[0002] The 048 motor cover is a key component of the blower or motor housing, typically referring to a specific model (such as the 048 type) blower motor cover. In casting, it is a thin-walled complex structural component that requires sand core assembly to form the inner cavity. The sand core is made of casting sand, resin binder, and other materials, and must possess high strength, permeability, and collapsibility to withstand the impact of high-temperature molten metal. Currently, when the tooling is assembled and then cast, the connection between the sand core components is relatively unstable, and it is prone to loosening under the impact of molten metal, affecting the product yield. Therefore, a 048 motor cover core assembly tooling is proposed. Utility Model Content

[0005] Preferably, the base includes a support frame, two sets of brackets are connected and arranged on the inner side of the support frame, and fitting grooves are opened on both sides of the support frame. The side plate is connected and arranged on the inner side of the fitting groove, and an insertion hole is opened at the bottom end of the support frame. The sand core seat is connected and arranged between the brackets.

[0006] Preferably, the sand core holder has side blocks on both sides, and a positioning block is connected to the top of the side blocks. The cover plate has mating holes on both sides corresponding to the positioning blocks, and the two positioning blocks are of different sizes.

[0007] Preferably, the top of the sand core holder has a slot, and the bottom of the sand core frame is connected to a corresponding slot with a mounting bracket.

[0008] Preferably, the base has multiple threaded holes at its bottom end.

[0009] Preferably, the middle end of the cover plate is located between the inner sides of the sand core frame.

[0010] In summary, this application includes the following beneficial technical effects:

[0011] The combination of the base and side plates facilitates the positioning of the sand core holder during placement. After placement, the top cover plate and the splicing of the base and sand core holder provide support for the sand core frame, thereby ensuring the accuracy of the sand core assembly, preventing loosening, ensuring its molding effect, and thus improving the yield rate.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-3 The present invention provides a technical solution: including a base 1, a side plate 2 connected to one side of the base 1, a guide hole 3 opened at the top of the base 1, a sand core seat 4 provided inside the base 1, a sand core frame 5 provided at the top of the sand core seat 4, a cover plate 6 connected to the top of the sand core frame 5 and the top of the sand core seat 4, and a positioning cone 7 connected to the bottom of the cover plate 6 corresponding to the guide hole 3.

[0018] Reference Figure 3 As shown, the base 1 includes a support frame 11. Two sets of brackets 12 are connected to the inner side of the support frame 11 for placing and supporting the sand core seat 4. The stability of the placement can be ensured by the restriction of the side plate 2. The support frame 11 has a fitting groove 13 on both sides, and the side plate 2 is connected to the inner side of the fitting groove 13. The bottom end of the support frame 11 has a insertion hole 14. When the sand core seat 4 is installed, the rod under the sand core seat 4 can be inserted into the insertion hole 14 to complete the positioning.

[0019] The top of the sand core holder 4 is provided with a slot 43, and the bottom of the sand core frame 5 is connected to the slot 43 with a bracket 51. After the sand core holder 4 is installed, the bracket 51 is used to lock into the slot 43, thereby assembling the sand core frame 5 on the top of the sand core holder 4.
