Description

Technical Field

[0001] This invention relates to the field of axial magnetic field motors, and more particularly to an axial magnetic field motor rotor disk, manufacturing equipment, rotor assembly, and manufacturing method. Background Technology

[0002] Axial field motors, also known as disc motors, have advantages such as small axial dimensions, high torque density, high power density, and high efficiency, and are widely used in electric vehicles, general industrial applications, and household appliances. When an axial field motor is running, the rotor is rotating and simultaneously subjected to gravity, bearing support force, centrifugal force, torque, and eccentric magnetic pull. Maintaining stable and vibration-free rotation requires close and consistent fit among all rotor components.

[0003] refer to Figure 1 Existing rotors generally include several magnets 1, a cage 2, and a retaining ring 3. The magnets 1 are integral structures and are magnetized, with their magnetic poles distributed axially. The magnets 1 are inserted into the cage 2, and the retaining ring 3 is fitted around the outer periphery of the cage 2 to limit and fix the magnets 1. However, it has the following drawbacks:

[0004] 1. The retainer 2 and the fixing ring 3 are made of prepreg, which is a sheet product made by impregnating the matrix with reinforcing fibers. The matrix material is mainly resin, which makes the material cost high. Moreover, the special shape of the retainer 2 makes the material utilization rate low, further increasing the cost.

[0005] 2. Both the retaining ring 3 and the retainer 2 require molding followed by machining. The retaining ring 3 is manufactured using winding molding, and the retainer 2 is manufactured using lamination molding. Lamination molding involves cutting the prepreg to the required size and shape of the product, stacking it into the required number of layers, and then placing it into a metal mold for forming. Winding molding involves winding the prepreg onto a mold core of a specific shape and then forming it in a metal mold. Stacking or winding the material before placing it into the mold consumes a significant amount of time, directly leading to low production efficiency. Furthermore, the manufacturing precision of molding is not high, requiring machining to adjust the dimensions, further reducing production efficiency and increasing production costs.

[0006] 3. To ensure a tight fit between the magnet 1, the retainer 2, and the fixing ring 3, all assembly contact surfaces must be coated with glue before assembly, resulting in low production efficiency, inability to automate, and high manual assembly costs.

[0007] 4. The existing technical route involves many assembly processes. In order to ensure assembly accuracy, the assembly dimensions of each component are required to be high, resulting in a low part qualification rate and high production management difficulty. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides an axial magnetic field motor rotor disk, manufacturing equipment, rotor assembly, and manufacturing method that improve production efficiency and reduce material costs.

[0009] According to one objective of the present invention, the present invention provides a manufacturing apparatus for an axial magnetic field motor rotor disk, the manufacturing apparatus comprising:

[0023] When there are gaps between the magnetized magnet and the upper and lower molded surfaces respectively, the forming cavity includes an inner ring forming cavity, an outer ring forming cavity, an inter-pole forming cavity, and an axial forming cavity. The area enclosed by the radially inner side of the magnetized magnet forms the inner ring forming cavity, the area between the radially outer side of the magnetized magnet and the annular surface forms the outer ring forming cavity, the area between two adjacent magnetized magnets forms the inter-pole forming cavity, and the axial forming cavity is formed between the magnetized magnet and the lower and upper molded surfaces respectively. The assembly includes an inner ring joint and an outer ring joint. The magnet comprises a joint, an inter-pole joint, and an axial joint. The inner ring joint is connected to the radially inner side of the magnetized magnet and is formed within the inner ring forming cavity. The outer ring joint is connected to the radially outer side of the magnetized magnet and is formed within the outer ring forming cavity. The inter-pole joint is connected between two adjacent magnetized magnets and is formed within the inter-pole forming cavity. The axial joint is provided on both axial sides of the magnetized magnet and is formed within the axial forming cavity.

[0024] In a preferred embodiment, the first positioning member includes two first frustum portions, which are connected to the lower mold surface, and the two first frustum portions are spaced apart circumferentially.

[0025] The magnetized magnet has positioning holes on both sides of its circumference, which are respectively connected to two adjacent first frustum portions located in different first positioning parts. The magnetized magnet abuts against the lower surface, and there is a gap between the magnetized magnet and the annular surface.

[0026] In a preferred embodiment, the first positioning member further includes a stepped portion, which connects the lower molded surface and the first frustum portion.

[0027] In a preferred embodiment, at least one of the lower mold, the upper mold, the first positioning member, the second positioning member, and the limiting member is made of a non-magnetic material.

[0028] In a preferred embodiment, the positioning ring is slidably connected relative to the base plate, so that the positioning ring, the fastener, the limiting member, and the second positioning member are pushed out as a whole relative to the base plate.

[0029] According to another objective of the present invention, the present invention also provides a method for manufacturing an axial magnetic field motor rotor disk, comprising the following steps:

[0030] a. A plurality of magnetized magnets are placed in the lower mold of a manufacturing equipment, wherein the lower mold is provided with a plurality of first positioning members arranged at circumferential intervals, and the magnetized magnets are circumferentially and radially confined between two adjacent first positioning members;

[0031] b. Arrange a second positioning member in the lower mold to axially limit the magnetized magnet between the first positioning member and the second positioning member;

[0032] c. Place the molding material into the molding cavity formed by the upper mold and the lower mold, and make the molding material form a composite body. The composite body is combined with the magnetized magnet to obtain the rotor disk.

[0033] According to another objective of the present invention, the present invention also provides an axial magnetic field motor rotor disk, comprising:

[0034] Several magnetized magnets;

[0035] A composite body is connected between each of the magnetized magnets, and the magnetized magnets are arranged at circumferential intervals.

[0036] The axial sides of the magnetized magnet are exposed outside the assembly, or the assembly completely encloses the magnetized magnet.

[0037] According to another objective of the present invention, the present invention also provides an axial magnetic field motor rotor assembly, including the rotor disk of the above embodiment. The axial magnetic field motor rotor assembly further includes a rotor shaft, bolts and a washer, the rotor disk being sleeved on the rotor shaft and fixed by the bolts and the washer.

[0038] Compared with existing technologies, this technical solution has the following advantages:

[0039] The assembly is injection molded, which ensures good consistency among the components of the rotor disk, improves the product qualification rate, and at the same time uses the assembly to limit and fix the magnetized magnet, that is, to combine the existing cage and fixing ring into one, reduce the number of parts and assembly steps, simplify the process route, avoid the use of prepreg molding process to increase material costs, and improve production efficiency.

[0040] The manufacturing equipment provides the first positioning element and the second positioning element, which circumferentially position a plurality of the magnetized magnets on the lower mold. Then, within the molding cavity formed by the upper and lower molds, an assembly of the magnetized magnets is injection molded, ensuring that the magnetized magnets do not shift due to mutual attraction, thereby guaranteeing product consistency and effectively improving the product qualification rate. The manufacturing equipment is made of a non-magnetic material to avoid affecting the positioning effect of the magnetized magnets. The positioning ring is slidably connected relative to the base plate, allowing the positioning ring, the fasteners, the limiting element, and the second positioning element to be ejected as a whole relative to the base plate, so that the rotor disc can be removed.

Detailed Implementation

[0062] The following description is intended to disclose the present invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art. The basic principles of the invention defined in the following description can be applied to other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0063] First Embodiment

[0064] like Figures 2 to 4 As shown, the axial magnetic field motor rotor disk 1000 includes:

[0065] Several magnetized magnets, 100;

[0066] A connector 200 is connected between each of the magnetized magnets 100, and the magnetized magnets 100 are arranged at circumferential intervals.

[0067] Preferably, the composite body 200 completely encloses each composite body 200 so that the plurality of magnetized magnets 100 are circumferentially spaced within the composite body 200, thereby ensuring structural strength.

[0068] refer to Figure 3 The assembly 200 includes an inner ring assembly 210, an outer ring assembly 220, and an inter-pole assembly 230. The inner ring assembly 210 is injection-molded radially inside the magnetized magnet 100, and the outer ring assembly 220 is injection-molded radially outside the magnetized magnet 100, so that the magnetized magnet 100 is radially limited between the inner ring assembly 210 and the outer ring assembly 220. The inter-pole assembly 230 is injection-molded between two adjacent magnetized magnets 100, so that the magnetized magnet 100 is circumferentially limited between two adjacent inter-pole assemblies 230. Since the inner ring assembly 210, the outer ring assembly 220, and the inter-pole assembly 230 are integrally injection-molded onto the magnetized magnet 100, they provide axial positioning for the magnetized magnet 100. (Reference) Figure 2 Furthermore, axial joint portions 240 can be injection molded on both sides of the magnetized magnet 100 to axially limit the magnetized magnet 100 between the two axial joint portions 240. The inner ring joint portion 210, the outer ring joint portion 220, the inter-pole joint portion 230, and the axial joint portion 240 are integrally injection molded.

[0069] The inner ring joint 210 and the outer ring joint 220 are annular. The inter-pole joint 230 connects the inner ring joint 210 and the outer ring joint 220. The inter-pole joint 230 is injection molded between two adjacent magnetized magnets 100. The magnetized magnets 100 are trapezoidal, and their width gradually increases radially from the inside to the outside. Therefore, the width of the inter-pole joint 230 also gradually increases radially from the inside to the outside, i.e., the inter-pole joint 230 is also trapezoidal. The axial dimensions of the inner ring joint 210, the outer ring joint 220, the inter-pole joint 230, and the magnetized magnets 100 are equal. At this time, the axial joint 240 can uniformly cover the inner ring joint 210, the outer ring joint 220, the inter-pole joint 230, and the magnetized magnets 100 to obtain a result as shown in the figure. Figure 3 The rotor disk 1000 is shown.

[0070] refer to Figure 2 and Figure 3 The magnetized magnet 100 has filling grooves 110 on both sides of its circumference, and the composite body 200 is filled in the filling grooves 110 to increase the bonding ability between the magnetized magnet 100 and the composite body 200.

[0071] The filling groove 110 extends radially through the magnetized magnet 100. The cross-section of the filling groove 110 may be semi-circular, but is not limited to this. Moreover, there may be multiple filling grooves 110.

[0072] Continue to refer to Figure 2 The magnetized magnet 100 has positioning holes 120 on both circumferential sides, and the positioning holes 120 penetrate the magnetized magnet 100 along its axial direction. The positioning holes 120 have a semi-circular cross-section, but are not limited to this. The positioning structure of the manufacturing equipment, in conjunction with the positioning holes 120, positions the magnetized magnet 100 within the manufacturing equipment, ensuring its stable positioning and thus guaranteeing product consistency. Specifically, the magnetized magnet 100 is a magnetic steel, which allows it to be firmly secured within the manufacturing equipment. Then, an assembly 200 encapsulating the magnetized magnet 100 is formed by injection molding. (Refer to...) Figure 3 The assembly 200 completely encloses the outer surface of each of the magnetized magnets 100 to form a rotor disk 1000 with a radial dimension much larger than its axial dimension.

[0073] Continue to refer to Figure 2 The positioning hole 120 is located at the radial center of the magnetized magnet 100, thereby ensuring the positioning effect. Furthermore, the positioning hole 120 and the filling groove 110 intersect.

[0074] In summary, the assembly 200 is formed by injection molding, prepreg molding, or molding with short-fiber resin material, ensuring good consistency among the components of the rotor disk and improving the product qualification rate. At the same time, the assembly 200 is used to limit and fix the magnetized magnet 100, that is, to combine the existing cage and fixing ring into one, reducing the number of parts and assembly steps, simplifying the process route, avoiding the increase in material costs caused by the use of prepreg molding process, and improving production efficiency.

[0075] Second Embodiment

[0076] like Figure 5 As shown, the axial magnetic field motor rotor disk of the second embodiment differs from that of the first embodiment in that the axial sides of the magnetized magnet 100 are exposed outside the assembly 200.

[0077] The assembly 200 includes an inner ring assembly 210, an outer ring assembly 220, and an inter-pole assembly 230. The inner ring assembly 210 is injection molded on the radially inner side of the magnetized magnet 100, and the outer ring assembly 220 is injection molded on the radially outer side of the magnetized magnet 100, so that the magnetized magnet 100 is radially limited between the inner ring assembly 210 and the outer ring assembly 220. The inter-pole assembly 230 is injection molded between two adjacent magnetized magnets 100, so that the magnetized magnet 100 is circumferentially limited between two adjacent inter-pole assemblies 230. Since the inner ring assembly 210, the outer ring assembly 220, and the inter-pole assembly 230 are integrally injection molded on the magnetized magnet 100, they serve to axially limit the magnetized magnet 100.

[0078] Third Embodiment

[0079] like Figures 6 to 8 As shown, the axial magnetic field motor rotor assembly includes a rotor disk 1000 in the first embodiment or the second embodiment. The axial magnetic field motor rotor assembly also includes a rotor shaft 2000, bolts 4000 and a pad 3000. The rotor disk 1000 is sleeved on the rotor shaft 2000 and fixed by the bolts 4000 and the pad 3000.

[0080] like Figure 7 As shown, the rotor disk 1000 has a central hole 1002 located at the center of the rotor disk 1000. The rotor shaft 2000 includes a shaft body 2001 and a stepped plate 2002 connected to the shaft body 2001. During assembly, the shaft body 2001 passes through the central hole 1002 of the rotor disk 1000, and the stepped plate 2002 and the pad 3000 are clamped on both axial sides of the rotor disk 1000. Then, the stepped plate 2002, the rotor disk 1000, and the pad 3000 are connected by bolts 4000 to complete the assembly of the rotor assembly. (Refer to...) Figures 6 to 8 .

[0081] Continue to refer to Figure 7 The rotor disk 1000 is also provided with a plurality of mounting holes 1001, which surround the central hole 1002. The mounting holes 1001 are used for the bolts 4000 to pass through. Similarly, the pad 3000 is provided with a pad through hole 3001 for the bolts 4000 to pass through. The stepped plate 2002 is provided with a threaded hole 2003 for the bolts 4000 to be screwed in.

[0082] Fourth embodiment

[0083] like Figures 9 to 23As shown, the manufacturing equipment for the axial magnetic field motor rotor disk is used to manufacture the rotor disk 1000 with magnetized magnets 100 and a coupling body 200 in the first embodiment. The manufacturing equipment includes:

[0084] Lower mold 6100;

[0085] A plurality of first positioning elements 6300 are arranged circumferentially on the lower mold 6100, and the magnetized magnet 100 is circumferentially and radially confined between two adjacent first positioning elements 6300.

[0086] A plurality of second positioning elements 6400 are detachably fixed to the lower mold 6100. The second positioning elements 6400 correspond one-to-one with the first positioning elements 6300. The magnetized magnet 100 is axially confined between the first positioning elements 6300 and the second positioning elements 6400.

[0087] When the lower mold 6100 and the upper mold 6200 are closed, a forming cavity 6000 is also formed between the lower mold 6100 and the upper mold 6200, wherein the connecting body 200 is formed in the forming cavity 6000, and the connecting body 200 is combined with the magnetized magnet 100 to form the rotor disk 1000.

[0088] The manufacturing equipment injection molds the magnetically charged magnets 100, forming a composite body 200 that connects and limits the magnets 100, so that a plurality of magnets 100 are circumferentially spaced and confined between the composite body 200. The manufacturing equipment provides a first positioning member 6300 and a second positioning member 6400 to circumferentially limit the plurality of magnets 100 on the lower mold 6100. Then, within the molding cavity 6000 formed by the upper mold 6200 and the lower mold 6100, the composite body 200 connecting the magnets 100 is injection molded, ensuring that the magnets 100 do not shift due to mutual attraction, thereby ensuring product consistency and effectively improving the product qualification rate.

[0089] like Figure 9 and Figure 22 As shown, the lower mold 6100 further includes a lower mold base 6130, which has a lower mating surface 6130a. The upper mold 6200 includes an upper mold base 6220, which has an upper mating surface 6220a. The lower mating surface 6130a and the upper mating surface 6220a are opposite each other, and the upper mold 6200 and the lower mold 6100 are opened and closed.

[0090] Continue to refer to Figure 9 and Figure 22 The lower mating surface 6130a is provided with a guide post 6140, and the upper mating surface 6220a is provided with a guide hole 6240 adapted to the guide post 6140. That is, the guide post 6140 is inserted into the guide hole 6240 so that the lower mold 6100 and the upper mold 6200 move along the axial direction of the guide post 6140 and complete the mold opening and closing.

[0091] like Figure 11 , Figure 17 , Figure 18 and Figure 22 As shown, the lower mold 6100 includes:

[0092] The base plate 6110 has a lower profile 6000a on one side of its axial direction, and the first positioning member 6300 is disposed on the lower profile 6000a.

[0093] A positioning ring 6120 is arranged around the lower molded surface 6000a. A fixing surface 6120a is provided on one side of the positioning ring 6120 along its axial direction. The lower molded surface 6000a is recessed relative to the fixing surface 6120a to form the annular surface 6000b inside the positioning ring 6120. When the upper mold 6200 and the lower mold 6100 are closed, the upper mold 6200 abuts against the fixing surface 6120a.

[0094] Several first positioning elements 6300 are arranged circumferentially at intervals on the lower molded surface 6000a, with one magnetized magnet 100 positioned between adjacent two elements. (Reference) Figure 17 and Figure 18 The magnetized magnets 100 are arranged in a circularly spaced manner. The magnetized magnets 100 are arranged within the area enclosed by the annular surface 6000b, and gaps exist between each magnetized magnet 100 and both the lower molding surface 6000a and the annular surface 6000b to form the space of the molding cavity 6000. This allows the assembly 200 formed within the molding cavity 6000 to enclose the magnetized magnets 100.

[0095] Furthermore, the shapes of the lower molding surface 6000a and the annular surface 6000b define the shape of the rotor disk 1000. Since the base plate 6110 is circular, the lower molding surface 6000a is circular. Similarly, since the positioning ring 6120 is annular, the annular surface 6000b and the fixing surface 6120a are also annular. Because the lower molding surface 6000a is circular and the annular surface 6000b is annular, the rotor disk 1000 formed by injection molding in the molding cavity 6000 is disk-shaped. (Refer to...) Figure 3Of course, the shape of the molding cavity 6000 can be adjusted according to design requirements.

[0096] like Figure 9 As shown, the base plate 6110 and the positioning ring 6120 are embedded in the lower mold base 6130, and the fixing surface 6120a is flush with the lower mating surface 6130a, and the lower molding surface 6000a is recessed relative to the lower mating surface 6130a.

[0097] like Figure 13 and Figure 14 As shown, the first positioning member 6300 includes a stepped portion 6310 and two first frustum portions 6320. The stepped portion 6310 is connected between the lower profile 6000a and the first frustum portions 6320, and the two first frustum portions 6320 are arranged circumferentially.

[0098] refer to Figure 2 , Figure 14 , Figure 17 and Figure 18 The magnetized magnet 100 has positioning holes 120 on both circumferential sides, which are respectively connected to two adjacent first frustum portions 6320 located at different first positioning members 6300. The magnetized magnet 100 abuts against the stepped portion 6310. There is a gap between the magnetized magnet 100 and the lower molded surface 6000a for injection molding to form an axial joint portion 240. There is a gap between the magnetized magnet 100 and the annular surface 6000b for injection molding to form the outer ring joint portion 220. The area enclosed by the radially inner side of the magnetized magnet 100 is used to injection mold the inner ring joint portion 210. The area between two adjacent magnetized magnets 100 is used to injection mold the interpole joint portion 230. (Reference) Figure 3 , Figure 4 and Figure 18 .

[0099] The shape of the first frustum portion 6320 is adapted to the shape of the positioning hole 120. The magnetized magnet 100 is inserted axially between two adjacent first positioning members 6300 along the base plate 6110 and is located in different first positioning members 6300. The two adjacent first frustum portions 6320 are respectively inserted into the positioning holes 120 on both sides of the same magnetized magnet 100 to limit the magnetized magnet 100 radially and circumferentially.

[0100] refer to Figure 14 The stepped portion 6310 is waist-shaped, and the two first frustum portions 6320 are located on both sides of the length direction of the stepped portion 6310, and the distance between the two first frustum portions 6320 defines the distance between the two magnetized magnets 100.

[0101] like Figure 15 As shown, the second positioning member 6400 has an oblong cross-section, and its bottom has two second frustum portions 6410. When the second positioning member 6400 and the first positioning member 6300 jointly limit the axial movement of the magnetized magnet 100, the second positioning member 6400 and the first positioning member 6300 correspond one-to-one, and the two second frustum portions 6410 of the second positioning member 6400 are respectively positioned and connected to two adjacent positioning holes 120 of different magnetized magnets 100, for reference. Figure 20 That is, each of the second positioning elements 6400 is the same as the first positioning element 6300, and corresponds to two of the magnetized magnets 100 respectively.

[0102] like Figure 16 and Figure 19 As shown, the manufacturing equipment also includes a plurality of limiting members 6500, each of which corresponds to one of the magnetized magnets 100. One end of each limiting member 6500 is fixed to the fixing surface 6120a, and the other end of each limiting member 6500 is disposed opposite to the magnetized magnet 100. A second positioning member 6400 is limited between two adjacent limiting members 6500.

[0103] The function of the limiting member 6500 is to limit the second positioning member 6400, so that the magnetized magnet 100 is axially limited between the first positioning member 6300 and the second positioning member 6400. Specifically, the limiting member 6500 has limiting holes 6510 on both sides of its circumference, corresponding to the positioning holes 120. The second positioning member 6400 is inserted into two adjacent limiting holes 6510 located in different limiting members 6500, and the second positioning member 6400 is provided with a second frustum portion 6410 that is positioned and connected in the positioning hole 120.

[0104] The limiting hole 6510 is semi-circular to accommodate the installation of the second positioning member 6400, which has an oblong cross-section. Preferably, refer to... Figure 16 and Figure 19 The limiting hole 6510 is provided with an angled 6511 on the side opposite to the magnetized magnet 100 so that the second positioning member 6400 can pass through and be inserted into the limiting hole 6510.

[0105] The limiting member 6500 and the magnetized magnet 100 are adapted to each other so that the limiting holes 6510 on both sides of the circumference of the limiting member 6500 correspond to the positioning holes 120 on both sides of the circumference of the magnetized magnet 100. The limiting member 6500 is trapezoidal, and the width of the limiting member 6500 gradually increases radially from the inside to the outside.

[0106] like Figure 16 , Figure 19 and Figure 22 As shown, the manufacturing equipment also includes a fastener 6600. A limiting notch 6520 is provided on the radially outer side of the limiting member 6500. The fastener 6600 is adapted to be installed in the limiting notch 6520 and screwed onto the fixing surface 6120a. An avoidance hole 6230 is provided on the upper mold 6200 to avoid the fastener 6600.

[0107] refer to Figure 11 and Figure 12 The positioning ring 6120 has several circumferentially spaced countersunk holes 6121. The fastener 6600 includes a bolt 6610 and a nut 6620. One bolt 6610 is arranged in each countersunk hole 6121. The head of the bolt 6610 is embedded in the side of the positioning ring 6120 away from the fixing surface 6120a, while the tail of the bolt 6610 protrudes from the fixing surface 6120a and is located in the notch 6520 of the limiting member. The nut 6620 is screwed onto the tail of the bolt 6610, so that the limiting member 6500 is clamped between the fixing surface 6120a and the nut 6620. The surface of the bolt 6610 that contacts the limiting member 6500 is a smooth surface.

[0108] The limiting member 6500 is positioned opposite the fastener 6600 via the limiting member notch 6520 and is inserted between the fixing surface 6120a and the nut 6620, so that the fastener 6600 is fixed within the limiting member notch 6520 of the limiting member 6500, and the limiting member 6500 is fixed on the fixing surface 6120a. Figure 22 and Figure 23 As shown, a filler 6210 is provided on the upper mold 6200. The filler 6210 fills between the limiting members 6500, so that the surface of the filler 6210 and the limiting members 6500 facing the lower mold surface 6000a is the upper mold surface 6000c. There is a gap between the upper mold surface 6000c and the magnetized magnet 100, that is, the gap between the two is used for injection molding the axial joint 240. (Refer to...) Figure 3 .

[0109] The thickness of the filler 6210 is equal to the thickness of the limiting member 6500, so that the filler 6210 and the limiting member 6500 are flush with the surface of the lower molded surface 6000a and form the upper molded surface 6000c.

[0110] Specifically, the filler 6210 includes a disk 6211 and a plurality of support rods 6212. The plurality of support rods 6212 are circumferentially spaced and connected to the outer periphery of the disk 6211. The disk 6211 fills the area enclosed by the radially inner side of the limiting member 6500. The support rods 6212 fill the space between two adjacent limiting members 6500. The support rods 6212 are provided with filler notches 6213 to avoid the second positioning member 6400.

[0111] like Figure 22 and Figure 23 As shown, the upper mold 6200 includes an upper mold base 6220, the upper mold base 6220 having an upper mating surface 6220a and a fitting surface 6250, the fitting surface 6250 being recessed relative to the upper mating surface 6220a, the filler 6210 being approximately flush with the upper mating surface 6220a, the fitting surface 6250 being provided between two adjacent support rods 6212, and the clearance hole 6230 being formed on the fitting surface 6250, that is, when the lower mold 6100 and the upper mold 6200 are closed, the limiting member 6500 is fitted onto the fitting surface 6250 and accommodated between two adjacent support rods 6212.

[0112] refer to Figure 18 If the fixed surface 6120a and the lower mold surface 6000a are flush, then the annular surface 6000b is formed on the upper mold 6200.

[0113] refer to Figure 3 , Figure 4 , Figure 20 and Figure 23The molding cavity 6000 includes an inner ring molding cavity 6001, an outer ring molding cavity 6002, an inter-pole molding cavity 6003, and an axial molding cavity 6004. The area enclosed by the radially inner side of the magnetized magnet 100 forms the inner ring molding cavity 6001, which is used for injection molding the inner ring joint 210. The outer ring molding cavity 6002 is formed between the radially outer side of the magnetized magnet 100 and the annular surface 6000b, and is used for injection molding the outer ring joint 220. The inter-pole molding cavity 6003 is formed between two adjacent magnetized magnets 100, and is used for injection molding the inter-pole joint 230. The axial molding cavity 6004 is formed between the magnetized magnet 100 and the lower molded surface 6000a and the upper molded surface 6000c, respectively, and is used for injection molding the axial joint 240.

[0114] like Figure 13 and Figure 23 As shown, the lower molded surface 6000a has a lower central boss 6111 on its central protrusion, and the disc 6211 has an upper central boss 6214 on its central protrusion. When the upper mold 6200 and the lower mold 6100 are closed, the lower central boss 6111 and the upper central boss 6214 abut against each other, so that the center hole 1002 is formed at the center of the rotor disc 1000. (Refer to...) Figure 3 Similarly, the lower molded surface 6000a is provided with a plurality of lower mounting bosses 6112, and the disc 6211 is provided with a plurality of upper mounting bosses 6215. When the upper mold 6200 and the lower mold 6100 are closed, the lower mounting bosses 6112 and the upper mounting bosses 6215 correspond one-to-one and abut against each other to form the mounting hole 1001 of the rotor disc 1000. (Refer to...) Figure 3 .

[0115] At least one of the lower mold 6100, the upper mold 6200, the first positioning member 6300, the second positioning member 6400, and the limiting member 6500 is made of a non-magnetic material. This is to prevent it from being magnetic and affecting the positioning effect of the magnetized magnet 100 on the manufacturing equipment. Preferably, all of the lower mold 6100, the upper mold 6200, the first positioning member 6300, the second positioning member 6400, and the limiting member 6500 are made of non-magnetic materials.

[0116] The positioning ring 6120 is slidably connected relative to the base plate 6110, so that the positioning ring 6120, the fastener 6600, the limiting member 6500, and the second positioning member 6400 are ejected as a whole relative to the base plate 6110. After the lower mold 6100 and the upper mold 6200 are opened, the manufacturing equipment can provide an ejection mechanism, which acts on the positioning ring 6120, so that the positioning ring 6120, the fastener 6600, the limiting member 6500, and the second positioning member 6400 are ejected as a whole relative to the base plate 6110, so as to remove the rotor disk 1000.

[0117] In addition, the rotor disk 1000 can be ejected by a ejector pin, wherein the positioning ring 6120 and the base plate 6110 can be fixedly connected. After the fastener 6600, the limiting member 6500 and the second positioning member 6400 are removed, the ejector pin is ejected from the lower molded surface 6000a so as to remove the rotor disk 1000.

[0118] like Figure 3 As shown, when the rotor disk 1000 is removed from the manufacturing equipment and the assembly 200 is separated from the first positioning member 6300 and the second positioning member 6400, slots 201 are formed on both axial sides of the assembly 200, which are opposite to the first positioning member 6300 and the second positioning member 6400. Then, an insulating member can be filled into the slots 201 to isolate air and prevent the magnetized magnet 100 from rusting. The insulating member can be glue.

[0119] In summary, the manufacturing equipment provides the first positioning element 6300 and the second positioning element 6400, which circumferentially limit the magnetized magnets 100 on the lower mold 6100. Then, within the molding cavity 6000 formed by the upper mold 6200 and the lower mold 6100, an assembly 200 is formed by injection molding, ensuring that the magnetized magnets 100 do not shift due to mutual attraction, thereby ensuring product consistency and effectively improving the product qualification rate. The manufacturing equipment is made of non-magnetic material to avoid affecting the positioning effect of the magnetized magnets 100. The positioning ring 6120 is slidably connected relative to the base plate 6110, so that the positioning ring 6120, the fastener 6600, the limiting element 6500, and the second positioning element 6400 are ejected as a whole relative to the base plate 6110, so that the rotor disk 1000 can be removed.

[0120] Fifth embodiment

[0121] The manufacturing equipment of the fifth embodiment is used to manufacture the rotor disk 1000 with magnetized magnet 100 and assembly 200 in the second embodiment. It differs from the fourth embodiment in that the first positioning member 6300 has only two first frustum portions 6320, so that the magnetized magnet 100 abuts against the lower molded surface 6000a, that is, there is no gap between the upper molded surface 6000c and the magnetized magnet 100, and the limiting member 6500 abuts directly against the magnetized magnet 100.

[0122] That is, the magnetized magnets 100 respectively abut against the upper molded surface 6000c and the lower molded surface 6000a. At this time, the forming cavity 6000 includes an inner ring forming cavity 6001, an outer ring forming cavity 6002, and an inter-pole forming cavity 6003. The area enclosed by the radially inner side of the magnetized magnets 100 forms the inner ring forming cavity 6001. The radially outer side of the magnetized magnets 100 forms the outer ring forming cavity 6002 between the annular surface 6000b. The inter-pole forming cavity 6003 is formed between two adjacent magnetized magnets 100. Only in this way can a shape be formed as described above. Figure 5 The rotor disk 1000 shown, i.e., the magnetized magnet 100, has its axial sides exposed outside the assembly 200.

[0123] Sixth Embodiment

[0124] like Figure 9 , Figure 10 , Figures 17 to 22 As shown, the manufacturing method of the axial magnetic field motor rotor disk includes the following steps:

[0125] a. A plurality of magnetized magnets 100 are placed in the lower mold 6100 of a manufacturing equipment, wherein the lower mold 6100 is provided with a plurality of first positioning members 6300 arranged circumferentially, and the magnetized magnets 100 are circumferentially and radially confined between two adjacent first positioning members 6300.

[0126] b. Arrange a second positioning member 6400 in the lower mold 6100 to axially limit the magnetized magnet 100 between the first positioning member 6300 and the second positioning member 6400;

[0127] c. Place the molding material into the molding cavity 6000 formed by the closing of the upper mold 6200 and the lower mold 6100, and form a composite body 200 with the molding material. The composite body 200 is then combined with the magnetized magnet 100 to obtain the rotor disk 1000.

[0128] In step a, the positioning hole 120 of the magnetized magnet 100 is used in conjunction with the first positioning member 6300 to confine the magnetized magnet 100 between two adjacent first positioning members 6300, for reference. Figure 17 and Figure 18 Then, the limiting member 6500 corresponding to the magnetized magnet 100 is fixed on the fixing surface 6120a, for reference. Figure 19 Repeat the above steps to assemble another magnetized magnet 100 and the corresponding limiting member 6500. Then, in step b, insert a second positioning member 6400 between two adjacent limiting members 6500. The second positioning member 6400 is positioned between the two adjacent limiting members 6500 and is inserted into the positioning hole 120 of the magnetized magnet 100. (Refer to...) Figure 20 The above steps are then repeated until all the magnetized magnets 100 are fully inserted into the lower mold 6100, as shown in the reference. Figure 21 Then, the mold closing and opening steps of the upper mold 6200 and the lower mold 6100 are performed.

[0129] The composite 200 can be injection molded or compression molded, and the molding material can be plastic or prepreg, etc. When the composite 200 is injection molded from plastic, in step c, plastic material is injected into the molding cavity 6000 formed by the upper mold 6200 and the lower mold 6100, so that the plastic material forms the composite 200 after curing.

[0130] After the rotor disk 1000 is removed from the manufacturing equipment and the assembly 200 is disengaged from the first positioning member 6300 and the second positioning member 6400, slots 201 opposite to the first positioning member 6300 and the second positioning member 6400 are formed on both axial sides of the assembly 200. Then, after step e, the method further includes:

[0131] An insulating material is filled into the slot 201 to prevent the magnetized magnet 100 from rusting by isolating it from air. The insulating material can be glue.

[0132] The method for manufacturing the axial magnetic field motor rotor disk can utilize the manufacturing equipment of the fourth embodiment to manufacture the rotor disk 1000 of the first embodiment. Alternatively, the manufacturing equipment of the fifth embodiment can be used to manufacture the rotor disk 1000 of the second embodiment.

[0133] The assembly 200 is injection molded, meaning the rotor disk is produced using an injection mold. This ensures good consistency among the components of the rotor disk, improving product yield. Simultaneously, the assembly 200 is used to limit and fix the magnetized magnet 100, combining the existing retainer and fixing ring into one unit. This reduces the number of parts and assembly steps, simplifies the process, avoids increased material costs associated with prepreg molding, and improves production efficiency. Because of the reduced assembly steps, the injection molding and transfer processes of the assembly 200 can be completed by a robotic arm, thus achieving automated production.

[0134] The embodiments described above are only used to illustrate the technical ideas and features of the present invention. Their purpose is to enable those skilled in the art to understand the content of the present invention and implement it accordingly. The scope of patent application of the present invention should not be limited by these embodiments. That is, any equivalent changes or modifications made in accordance with the spirit disclosed in the present invention still fall within the patent scope of the present invention.
