Detailed Implementation
[0022] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] Please see Figure 1-4 The present invention provides a technical solution: an adjustable core mold for winding transformer cores, including a mounting base 1, an mounting groove is provided on the upper part of the mounting base 1, a displacement mechanism 2 is installed inside the mounting base 1 to realize the width of the core mold is adjustable, a fixed core mold 3 is fixedly connected in the mounting groove above the mounting base 1, and a movable core mold 4 is slidably connected to one side of the fixed core mold 3. The fixed core mold 3 and the movable core mold 4 together constitute the core mold whole for winding the core.
[0024] A column 5 is welded above the mounting base 1. Several positioning holes are evenly opened on one side of the column body. An adjusting ring 6 is slidably connected to the column body of the column 5 to realize the height adjustment of the core mold. A locking mechanism 7 is welded at the connection between the adjusting ring 6 and the column 5. A limit plate 8 is welded to the top of the column 5 to prevent the adjusting ring 6 from slipping.
[0025] refer to Figure 2 , 3The displacement mechanism 2 includes a drive gear 21, the output end of a motor is fixedly connected to the middle of the drive gear 21, and the motor is installed inside the mounting base 1. A driven gear 22 is installed on one side of the drive gear 21, a first sliding plate 23 is installed on one side of the driven gear 22, and a second sliding plate 24 is installed on the other side of the drive gear 21. Several toothed grooves are opened on the opposite side of the first sliding plate 23 and the second sliding plate 24. The toothed grooves on the first sliding plate 23 mesh with the driven gear 22, and the toothed grooves on the second sliding plate 24 mesh with the drive gear 21. The drive gear 21 and the driven gear 22 are meshed and connected. When the motor is started, the drive gear 21 rotates, driving the driven gear 22 to rotate together, so that the first sliding plate 23 and the second sliding plate 24 achieve displacement in the same direction. The reciprocating displacement of the first sliding plate 23 and the second sliding plate 24 can be achieved by controlling the forward and reverse rotation of the motor.
[0026] Both the first sliding plate 23 and the second sliding plate 24 are riveted to the bottom surface of the moving core mold 4, so that while the first sliding plate 23 and the second sliding plate 24 are displaced, the moving core mold 4 is also moved in a stable manner, and the farthest distance of the moving core mold 4 is the lateral edge of the mounting groove in the mounting base 1.
[0027] refer to Figure 4 The locking mechanism 7 includes a connecting ring 71, which is welded above the adjusting ring 6 and sleeved on the outside of the column 5. A connecting plate 72 is welded to one side of the connecting ring 71, and a positioning member 73 is hinged to the connecting plate 72. The positioning member 73 is a column, and a telescopic spring 74 is fixedly connected to the lower end of the positioning member 73. The telescopic spring 74 is fixedly connected to the surface of the connecting ring 71. A positioning protrusion 75 is fixedly connected to the upper end of the positioning member 73, and the positioning protrusion 75 is adapted to the positioning hole on the column 5. The telescopic spring 74 and the positioning protrusion 75 are located on the same plane. Pressing one end of the telescopic spring 74 of the positioning component 73 will drive the adjusting ring 6 to move in the direction of the column 5. After releasing one end of the telescopic spring 74 of the positioning component 73, the positioning protrusion 75 is inserted into the positioning hole on the surface of the column 5, thereby fixing the adjusting ring 6 and adjusting its height. The evenly set positioning holes can accurately control the height distance on the column 5, saving measurement time. The core winding height is the height of the core mold above the adjusting ring 6.
[0028] In this embodiment, the required core width and height are set, and the displacement mechanism 2 is adjusted by driving the motor according to the set values, so that the moving core mold 4 is displaced within the mounting base 1, and the width formed by the moving core mold 4 and the fixed core mold 3 is adapted to the set core winding width; the height of the adjusting ring 6 is controlled by pressing the end of the telescopic spring 74 of the positioning member 73, so that the core winding height can be set. After the adjustment is completed, the core can be wound onto the core mold.
[0029] When the core needs to be removed after winding, the moving core mold 4 is moved towards the fixed core mold 3 by the displacement mechanism 2, so that the two half core molds are merged together. At this time, the core will automatically fall off the core mold and can be taken out directly from the top of the core mold. This avoids the frictional force that would cause damage to the core and core mold if the core is taken out directly after being tightly wound with the core mold.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
