Their core function is to process raw materials (metal, plastic, etc.) into standardized parts required for motors through specific processes (such as stamping, casting, injection molding, etc.).

[0003] However, the following problems were found in the implementation of the relevant technologies:

[0004] Existing motor end cover molds often lack positioning accuracy, which can easily lead to cavity misalignment during mold closing, resulting in poor dimensional consistency of the motor end cover. Inadequate design of the gating and venting structures can also lead to incomplete venting, causing defects such as air bubbles and shrinkage cavities, which affect the surface quality and structural strength of the end cover.

[0005] Furthermore, most ejection structures are poorly designed, resulting in an unstable demolding process that can easily damage the product; the high degree of integration between inserts and modules makes them difficult to process, replace, and maintain individually, leading to high maintenance costs; the base plates are not securely fixed and lack auxiliary positioning structures, resulting in poor overall mold stability and significant impact of vibration on product quality.

[0022] 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.

[0023] like Figures 1 to 4 As shown, this utility model provides a motor end cover mold, including an upper moving mold 5 and a lower moving mold 10. An upper fixed mold 6 is provided on the lower side of the upper moving mold 5, and a lower fixed mold 11 is provided on the lower side of the lower moving mold 10. An ejector plate 4 is provided on one side of the upper moving mold 5, the upper fixed mold 6, the lower moving mold 10 and the lower fixed mold 11. After molding, the upper moving mold 5 is separated from the upper fixed mold 6, and the lower moving mold 10 is separated from the lower fixed mold 11 (mold opening).

[0024] Specifically, an ejector plate 4 is provided with an ejector cover plate 3 on one side, and a foot plate 1 is symmetrically provided on one side of the ejector cover plate 3. Driven by the ejector cover plate 3, the ejector plate 4 transmits power through the ejector half holes 13 symmetrically opened on the outer side of the foot plate 1. The ejector ejects the molded motor end cover, completing the demolding process.

[0025] Furthermore, sleeves 2 are symmetrically arranged between the foot plate 1 and the ejector cover plate 3. The upper moving mold 5, the upper fixed mold 6, the lower moving mold 10, the lower fixed mold 11, the ejector plate 4, and the ejector cover plate 3 are all provided with positioning pins 9 that cooperate with the sleeves 2. The sleeves 2 symmetrically arranged between the foot plate 1 and the ejector cover plate 3 provide a reference for the positioning of subsequent modules in advance.

[0026] The upper moving mold 5 and the upper fixed mold 6, and the lower moving mold 10 and the lower fixed mold 11 are precisely connected through their respective positioning pins 9 (which cooperate with the sleeve 2) to ensure that there is no misalignment between the modules.

[0027] Furthermore, the outer side of the base plate 1 is symmetrically provided with ejector pin half holes 13, and the upper surface of the base plate 1 is symmetrically provided with bolt mounting grooves 12. The base plate 1 is fixed to the molding equipment through the bolt mounting grooves 12 symmetrically provided on its upper surface, providing stable support for the mold as a whole.

[0028] It is worth noting that sprue inserts 7 and venting inserts 8 are provided between the upper moving mold 5 and the upper fixed mold 6, as well as between the lower moving mold 10 and the lower fixed mold 11. Molten material is injected into the closed cavity through the sprue inserts 7 provided between the upper moving mold 5, the upper fixed mold 6, the lower moving mold 10, and the lower fixed mold 11. Gas inside the cavity is discharged in time through the venting inserts 8 to avoid defects such as air bubbles and material shortages in the product, and to ensure that the material fully fills the cavity and solidifies.

[0029] It is worth noting that an upper mold moving groove 51 is provided on one side of the upper mold moving mold 5, and an upper mold fixed groove 61 is provided on one side of the upper mold fixed mold 6. The upper mold fixed groove 61 and the upper mold moving groove 51 are used together. A lower mold moving groove 101 is provided on one side of the lower mold moving mold 10, and a lower mold fixed groove 111 is provided on one side of the lower mold fixed mold 11. The lower mold fixed groove 111 and the lower mold moving groove 101 are used together. The upper mold moving groove 51 of the upper mold moving mold 5 and the upper mold fixed groove 61 of the upper mold fixed mold 6 are closed. The lower mold moving groove 101 of the lower mold moving mold 10 and the lower mold fixed groove 111 of the lower mold fixed mold 11 are closed, together forming a complete cavity that matches the shape of the motor end cover.

[0030] Working principle: The base plate 1 is fixed to the molding equipment through the bolt mounting grooves 12 symmetrically opened on its upper surface, providing stable support for the mold as a whole; at the same time, the sleeves 2 symmetrically arranged between the base plate 1 and the ejector cover plate 3 provide a reference for the positioning of subsequent modules in advance.

[0031] The upper moving mold 5 and the upper fixed mold 6, and the lower moving mold 10 and the lower fixed mold 11 are precisely connected by their respective positioning pins 9 (which cooperate with the sleeve 2) to ensure that there is no misalignment between the modules. At this time, the upper moving groove 51 of the upper moving mold 5 and the upper fixed groove 61 of the upper fixed mold 6 are closed, and the lower moving groove 101 of the lower moving mold 10 and the lower fixed groove 111 of the lower fixed mold 11 are closed, together forming a complete cavity that matches the shape of the motor end cover.

[0032] The molten material is injected into the closed cavity through the sprue insert 7, which is installed between the upper moving mold 5, the upper fixed mold 6, the lower moving mold 10, and the lower fixed mold 11; the gas inside the cavity is discharged in time through the venting insert 8 to avoid defects such as air bubbles and material shortage in the product, and to ensure that the material fully fills the cavity and solidifies.

[0033] After molding is completed, the upper moving mold 5 separates from the upper fixed mold 6, and the lower moving mold 10 separates from the lower fixed mold 11 (mold opening); the ejector plate 4, driven by the ejector cover plate 3, transmits power through the ejector pin half holes 13 symmetrically opened on the outside of the foot plate 1, and the ejector pin pushes out the molded motor end cover, completing the demolding process.
