[0027] The relative arrangement of parts and steps, numerical expressions, and numerical values set forth in the examples are not intended to limit the scope of the present application unless otherwise specifically stated. It is to be understood that the drawings are not necessarily to scale of the various parts shown in the drawings. Techniques, methods, and apparatus known to those of ordinary skill are not discussed in detail because they would be understood that such techniques, methods, and apparatus are considered part of the art. In all examples shown and discussed herein, any specific values are to be interpreted as merely illustrative and not limiting. Thus, other examples of example embodiments can have different values. It is noted that like numbers and letters on the figures identify like parts throughout the several views, and thus, once an item is defined in one figure, it is not necessary to discuss it further in connection with other figures where it is understood that the item will be similarly constructed and function in the same manner.

[0028] In the description of the present application, it is to be understood that the orientation words such as "front, back, up, down, left, right", "horizontal, vertical, perpendicular, horizontal" and "top, bottom" and the like indicated orientation or position relationship is usually based on the orientation or position relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, these orientation words do not indicate and imply that the device or element referred to must have a particular orientation or be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the scope of protection of the present application; the orientation words "inner, outer" refer to the inner and outer relative to the contour of each component.

Since the two sliding shafts are coaxially arranged and there is no height difference, the rear mold assembly 1 and the front mold assembly 2 can share the same linear guide rail, simplifying the structure and reducing costs. Furthermore, only one motor I 41 is needed to drive both sliding shafts to rotate simultaneously. Specifically, the motor I 41 is connected to one of the sliding shafts through a transmission mechanism (which can be gear transmission, belt transmission, chain transmission, etc.). The first sliding shaft 31 and the second sliding shaft 32 are both screws, and the first sliding shaft 31 and the second sliding shaft 32 are coaxially connected by a spline joint. Rectangular splines, involute splines, and triangular splines can be used for connection, or other methods such as...

After the model of the wound coil is determined, the distance between the rear mold assembly 1 and the front mold assembly 2 is fixed, and only when the model of the coil is changed, the motor I 41 is used to drive the two sliding shafts to adjust the distance between the rear mold assembly 1 and the front mold assembly 2.

[0033] In one embodiment, as shown in the figure, Figure 2 The wire clamping assembly I 12 includes a wire clamping cylinder I 121, a wire clamping pull rod 122 and a wire clamping head, the wire clamping head includes a wire clamping base 123, a first wire clamping block 124, a second wire clamping block 125 and a pushing block 126, a wire clamping groove is formed on the top of the wire clamping base 123, the first wire clamping block 124 and the second wire clamping block 125 are installed in the cavity of the wire clamping base 123, the pushing block 126 is slidingly installed between the first wire clamping block 124 and the second wire clamping block 125 through the protrusions on the two sides, and the opposite surfaces of the left and right clamping blocks for installing one end of the pushing block 126 are inclined surfaces, so that the left and right clamping blocks can form a wedge-shaped or triangular or trapezoidal space at this end, and the space is narrow at one end close to the wire clamping groove and wide at the other end, and the pushing block 126 matches the shape of the space and is wedge-shaped or triangular or trapezoidal; the wire clamping cylinder 1 pulls the pushing block 126 through the extension and contraction of the wire clamping pull rod 122, so that the first wire clamping block 124 and the second wire clamping block 125 are close to or separated from each other, thereby clamping or releasing the bridge wire.

[0034] In one embodiment, as shown in the figure, Figure 3As shown, the clamping assembly II 14 includes a clamping cylinder II 141, a clamping base 142, a clamping pressure plate 143 and two clamping guide plates 144, the two clamping guide plates 144 are slidingly installed on the two sides of the clamping base 142, specifically, one end of the clamping guide plate 144 is fixed on the clamping pressure plate 143 through a screw, and the other end is located in the sliding groove on the two sides of the clamping base 142, the clamping cylinder II 141 drives the clamping pressure plate 143 to move close to or away from the clamping base 142 under the guidance of the clamping guide plate 144, which can be used to clamp the wire selected by the wire selection mechanism, so that the mold can be wound.

[0035] In one embodiment, the front mold assembly 2 is installed on the linear guide rail through the second sliding seat 23; the front mold assembly 2 includes a front mold arm 21 and a wire pushing ring 22, the outer profile of the front mold arm 21 has multiple steps, the wire pushing ring 22 is slidingly installed on the linear guide rail pair 25 on the front mold arm 21 through the U-shaped wire pushing plate 24, specifically, a linear guide rail is installed on the side of the front mold arm 21 close to the rear mold arm 11 along the vertical direction, two sliding grooves are opened on the side of the front mold arm 21 away from the rear mold arm 11 along the vertical direction, the wire pushing ring 22 is connected with the U-shaped wire pushing plate 24 and the two open ends of the wire pushing ring 22 are located in the sliding grooves to slide up and down along the sliding grooves, the wire pushing plate 24 is installed on the linear guide rail on the front mold arm 21 through a sliding block, the wire pushing plate 24 is connected with the wire pushing lifting cylinder 26 and drives the wire pushing ring 22 to slide down along the front mold arm 21 under the drive of the wire pushing lifting cylinder 26, so as to push the wound coil down.

[0036] Because the coil is wound tightly on the rear mold arm 11 and the front mold arm 21, it is difficult to push it down through the wire pushing ring 22 on the front mold assembly 2 at this time, but if the rear mold assembly 1 and the front mold assembly 2 move towards each other to reduce the distance therebetween at this time, the coil is easy to be pushed down, the movement of the front mold assembly 2 will damage the wire hanging cup, therefore, the moving seat 42 is installed on the first sliding shaft 31 through a bearing and the moving seat 42 is driven by the moving seat cylinder 43, because the first sliding shaft 31 and the second sliding shaft 32 are key matched through the way as shown, and in the initial state, the first end of the first sliding shaft 31 is at a certain distance from the side wall of the insertion hole in the second sliding shaft 32, so at this time, the piston rod of the moving seat cylinder 43 is retracted (the piston rod is in the extended state when the coil is wound), so that the first sliding shaft 31 moves to the side close to the second sliding shaft 32 in the insertion hole of the second sliding shaft 32, so that the rear mold arm 11 moves to the direction close to the front mold arm 21, the distance between the rear mold arm 11 and the front mold arm 21 is reduced, which facilitates the pushing down of the coil.
