[0030] like Figures 1 to 7 As shown, the bearing mold 100 for stator core winding provided in this embodiment includes a mold body 10 and a guide adjustment block 20. The mold body 10 has a first surface 1a and a second surface 1b facing each other. A positioning groove 11 is formed on both the first surface 1a and the second surface 1b for inserting and removing the ends of the segmented stator core 101. The guide adjustment block 20 is movably mounted on the mold body 10 along the length direction (direction of D1 in the figure). The guide adjustment block 20 has a guide surface 2a for abutting against the enameled wire 102. The guide surface 2a is an arc-shaped surface that protrudes outward along the length direction. At least one adjustment member 30 is provided between the mold body 10 and the guide adjustment block 20 for adjusting the relative position of the guide adjustment block 20 and the mold body 10 in the length direction.

[0031] The aforementioned support mold 100 for stator core winding includes a mold body 10 and a guide adjustment block 20. The guide adjustment block 20 is movably mounted on the mold body 10 along its length direction. The guide adjustment block 20 has a guide surface 2a for abutting against the enameled wire 102. An adjustment member 30 is provided between the mold body 10 and the guide adjustment block 20 to adjust the relative position of the guide adjustment block 20 and the mold body 10 in the length direction. In this way, by adjusting the position of the guide adjustment block 20 relative to the mold body 10 in the length direction through the adjustment member 30, the length dimension of the support mold in the length direction can be adjusted to shorten the bridge wire and thus ensure the motor performance.

[0032] See Figure 1The bearing mold 100 for stator core winding provided in this embodiment is provided with a positioning groove 11 for mounting segmented stator cores 101. In this embodiment, the bearing mold includes a mold body 10 and a guide adjustment block 20. The mold body 10 has a length direction (direction D1 in the figure) and a width direction (direction D2 in the figure). The guide adjustment block 20 is detachably connected to the mold body 10 and can move relative to the mold body 10 in the length direction. In this way, the position of the guide adjustment block 20 on the mold body 10 is adjusted to change the distance in the length direction between the end of the mold body 10 and the end of the guide adjustment block 20 in the bearing mold 100, thereby adjusting the length of the bridge wire formed by the enameled wire 102 on the guide adjustment block 20.

[0033] from Figure 1 and Figure 8 As can be seen, in this embodiment, the mold body 10 has a first surface 1a and a second surface 1b with opposite sides. A positioning groove 11 is formed on both the first surface 1a and the second surface 1b for inserting and removing the ends of the segmented stator cores 101. It is easy to understand that before winding, the two segmented stator cores 101 are respectively installed in the positioning groove 11 on the first surface 1a and the positioning groove 11 on the second surface 1b, and the two segmented stator cores 101 are respectively held on the supporting mold 100.

[0034] Please continue reading Figure 8 In this embodiment, the carrier mold 100 with the segmented stator core 101 installed is placed on the rotating seat 103 of the winding machine (not shown). The top of the rotating seat 103 is provided with a removable bottom mold base 1031. The bottom of the segmented stator core 101 located in the positioning groove 11 on the second surface 1b is supported in the groove (not shown) of the bottom mold base 1031. The rotating seat 103 is connected to a motor (not shown) and rotates under the drive of the motor, so as to drive the carrier mold 100 and the segmented stator core 101 located thereon to rotate together to realize winding. A wire clamp is installed on one side of the rotating seat 103. Component 104 clamps and secures the end of the enameled wire 102, and rotates together with the rotating seat 103. A pressing seat 105 is provided above the rotating seat 103. The pressing seat 105 is vertically and vertically positioned above the rotating seat 103. After the bearing mold 100 is placed on the rotating seat 103, it descends and abuts against the top of the segmented stator core 101 in the positioning groove 11 on the first surface 1a, thereby pressing the bearing mold 100 and the segmented stator core 101 onto the rotating seat 103, and can rotate together with the rotating seat 103.

[0035] See back Figures 1 to 7In this embodiment, the guide adjustment block 20 is movably mounted on the mold body 10 along its length. The guide adjustment block 20 has a guide surface 2a for abutting against the enameled wire 102, and the guide surface 2a is an arc-shaped surface that protrudes outward along the length direction. An adjustment member 30 is provided between the mold body 10 and the guide adjustment block 20 to adjust the relative position of the guide adjustment block 20 and the mold body 10 in the length direction. In this embodiment, the number of adjustment members 30 is, but not limited to, two. The two adjustment members 30 are spaced apart in the width direction. Each adjustment member 30 has a cross-section that is, but not limited to, circular, and extends along the length direction. Each adjustment member 30 has an abutment top 31 located at its end and abutting against the guide adjustment block 20. A first threaded portion 32 is provided on the adjustment member 30. An adjustment hole 12 extending along the length direction is formed on the mold body 10. A first threaded mating portion (not shown) that mates with the first threaded portion 32 is formed on the inner wall of the adjustment hole 12. It can be understood that the adjusting member 30 is installed on the mold body 10 and is connected to the mold body 10 through the first threaded part 32. The abutting top 31 of the adjusting member 30 extends out of the mold body 10 and abuts against the guide adjusting block 20. In this way, the length of the adjusting member 30 extending out of the mold body 10 can be adjusted by turning the adjusting member 30, thereby changing the position of the guide adjusting block 20 on the supporting mold 100.

[0036] In other embodiments, the adjusting member 30 may also be threaded onto the guide adjusting block 20 and abut against the mold body 10.

[0037] See Figures 1 to 7The bearing mold 100 provided in this embodiment also includes a fastener 40, on which a second threaded portion 41 is provided, and a fastening hole 21 is formed on the guide adjustment block 20. A second threaded mating portion (not shown) that mates with the second threaded portion 41 is formed on the inner wall of the fastening hole 21. The mold body 10 has an assembly hole 13 through which the fastener 40 passes. In this embodiment, the fastener 40 has, but is not limited to, a circular cross-section. The fastener 40 is located between two adjusting members 30. The fastener 40 has a head 42 in the mounting hole 13 of the mold body 10. A stepped structure 131 is formed in the mounting hole 13, which is matched with the head 42 of the fastener 40 to limit the fastener 40 from moving towards the guide adjusting block 20. The mounting hole 13 and the fastener 40 are in clearance fit. A second threaded portion 41 is formed on the end sidewall of the fastener 40. Thus, the fastener 40 can be turned, and the guide adjusting block 20 is driven to move by the threaded engagement of the second threaded portion 41 with the fastening hole 21. It should be noted that when adjusting the position of the guide adjusting block 20, the position of the adjusting member 30 is adjusted first. After the position of the adjusting member 30 is adjusted, the fastener 40 is turned to drive the guide adjusting block 20 to move towards the center of the mold body 10 until the guide adjusting block 20 abuts against the top 31 of the adjusting member 30, thus completing the adjustment of the position of the guide adjusting block 20.

[0038] See Figures 2 to 6 In this embodiment, the mold body 10 has a slot 14 for mounting the guide adjustment block 20. A mounting groove 141 is formed on the slot 14 for the guide adjustment block 20 to slide. The width dimension of the mounting groove 141 (the dimension in the width direction shown in the figure) is adapted to the width dimension of the guide adjustment block 20. In this way, when the guide adjustment block 20 is installed in the mounting groove 141 of the slot 14, the guide adjustment block 20 can be limited in the width direction by the groove wall of the mounting groove 141, that is, limited in the left and right direction (width direction shown in the figure), so that the overall structure is more stable.

[0039] See Figure 3 , Figure 4 and Figure 7 In this embodiment, a protrusion 142 is provided on the wall of the mounting groove 141. The protrusion 142 extends along the length direction. The guide adjustment block 20 has an insertion groove 22 for the protrusion 142 to slide. One end of the adjustment hole 12 and one end of the assembly hole 13 are formed on the surface of the protrusion 142. The thickness dimension of the protrusion 142 (the dimension in the vertical direction shown in the figure) is adapted to the height dimension of the insertion groove 22 (the dimension in the vertical direction shown in the figure). In this way, when the protrusion 142 slides into the insertion groove 22 of the guide adjustment block 20, it can be limited in the thickness direction (vertical direction shown in the figure) through the sliding cooperation between the insertion groove 22 and the protrusion 142, so that the mold has a stable connection structure.

[0040] See Figures 1 to 7 In this embodiment, a pair of guide limiting posts 50 are provided on the guide adjustment block 20. The two guide limiting posts 50 define a channel for the enameled wire 102 to move. In this way, the enameled wire 102 can be limited by the guide limiting posts 50, so that the enameled wire 102 can only be wound between the guide limiting posts 50, thereby preventing the enameled wire 102 from moving out of the channel defined by the two guide limiting posts 50, thus achieving the effect of protecting the wire.

[0041] See Figures 2 to 4 , Figure 7 In this embodiment, a bar magnet 60 is provided in the positioning groove 11 to attract and fix the segmented stator core 101. In this way, the bar magnet 60 has stronger magnetism and better attraction force.

[0042] See Figures 2 to 4 , Figure 8 The bearing mold 100 provided in this embodiment can have a positioning protrusion 15 in one of the positioning grooves 11 for positioning the segmented stator core 101, or it can have a positioning protrusion 15 in both positioning grooves 11. In this embodiment, a positioning protrusion 15 is provided in the positioning groove 11 of the first surface 1a and in the groove (not shown) of the bottom mold base 1031. The positioning protrusion 15 is located on the bottom surface of the positioning groove 11.

[0043] See Figures 1 to 7 In this embodiment, the mold body 10 includes an adjustment seat 16, a frame seat 17, and a tail seat 18 that are sequentially and detachably connected. The adjustment seat 16, the frame seat 17, and the tail seat 18 are connected by screws. The slot 14, the adjustment hole 12, and the assembly hole 13 are formed on the adjustment seat 16, and the positioning slot 11 is formed on the frame seat 17. In this way, the mold body 10 with a split structure is assembled. When it is necessary to wind a segmented stator core 101 of other specifications and sizes, only the matching frame seat 17 needs to be replaced. In this way, the mold has higher versatility and can reduce costs.

[0044] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
