Technical Field

[0001] The utility model relates to the technical field of transformer coil manufacturing, in particular to a combined mold for a planar transformer. Background Technique

[0002] The biggest difference between a planar transformer and a traditional transformer lies in the iron core and the coil winding. Small-sized E-shaped, RM-shaped or toroidal ferrite cores are used, and the winding is formed by stacking multiple printed circuit boards. The winding or copper sheets are stacked on the planar high-frequency iron core to form the magnetic circuit of the transformer.

[0003] A combined mold for manufacturing a transformer coil disclosed in the existing patent (publication number: CN219534281U) can wind copper wire through a first mold body and a second mold body, can block the coil through a first retaining disc and a second retaining disc, can adjust the length of the coil combined mold through a length adjusting mechanism, so that the coil combined mold can process and manufacture transformer coils of different models, can block the copper wire through a plurality of telescopic shielding mechanisms, can enable the coil combined mold to be installed on a winding device through a first round hole, a second round hole and two circular openings, can drive the first mold body and the second mold body to approach or move away from each other by the threaded rotation of a screw on the inner wall of a screw hole, can facilitate driving the screw to rotate through a wrench block and a hexagonal groove, can respectively install and fix the first retaining disc and the second retaining disc on the first mold body and the second mold body through a plurality of bolts, can enable the length of the telescopic shielding mechanism to be adjustable through a sleeve and an extension rod, and can threadedly connect the sleeve and the extension rod with the first retaining disc and the second retaining disc respectively through two stud bolts.

[0004] However, there are still certain deficiencies in the above technical solution when it is applied to the coil winding of a planar transformer. First of all, this equipment needs to disassemble multiple groups of bolts to connect and separate the upper mold and the lower mold before and after winding, and the operation is cumbersome and time-consuming, reducing production efficiency. Therefore, a combined mold for a planar transformer is proposed. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a combined mold for a planar transformer to solve the technical problem of cumbersome and time-consuming connection of multiple groups of bolts mentioned in the above background technique.

[0006] To achieve the above object, the utility model provides the following technical solution: a combined mold for a flat transformer, including a first retaining disc and a second retaining disc. The upper surface of the first retaining disc is provided with multiple groups of through holes in an equally spaced circular array. The center position of the upper surface of the first retaining disc is rotatably connected with a turntable. The upper surface of the turntable is provided with multiple groups of clamping holes in an equally spaced circular array. The upper surface of the turntable is threadedly connected with a fixing bolt, and the bottom end of the fixing bolt extends into the interior of the first retaining disc. The upper surface of the second retaining disc is fixedly connected with multiple groups of telescopic rods in an equally spaced circular array. The outer walls of the top ends of the telescopic rods are all provided with clamping grooves. The center position of the second retaining disc is rotatably connected with a rotating ring.

[0007] By adopting the above technical solution, first, twist and remove the fixing bolt, then rotate the turntable. At this time, the inner wall of the clamping hole disengages from the inside of the clamping groove. Then, move the first retaining disc and the turntable as a whole upward. At this time, multiple groups of telescopic rods are pulled out from the through holes, and finally, the rapid disassembly of the device is completed. The above operations are reversed to complete the rapid installation, improving the disassembly and assembly efficiency of the device. Secondly, the device is threadedly connected by a rotating cylinder and a threaded sleeve. First, hold the first handle and the second handle with both hands respectively, and then rotate the second handle and the rotating ring. At this time, the rotating cylinder drives the second retaining disc and multiple groups of second arc rods to move downward, realizing the rapid expansion of the length of the device. Then, multiple groups of first arc rods and second arc rods are interlaced and fastened, which can limit the second retaining disc and avoid generating a large lateral gap at the same time, preventing the situation of uneven thickness in some parts during coil winding and improving the winding quality.

[0008] Further, the cross-sectional area of the clamping hole is larger than the cross-sectional area of the top end of the telescopic rod. A fixing hole is opened at the contact position between the first retaining disc and the fixing bolt, and the outer wall of the top end of the telescopic rod penetrates through the through hole.

[0009] By adopting the above technical solution, the cross-sectional area of the clamping hole being larger than the cross-sectional area of the top end of the telescopic rod can reserve a moving space when the turntable rotates, and the fixing hole can limit and fix the turntable when the fixing bolt is inserted.

[0010] Further, the curved outer wall of the first retaining disc is fixedly connected with a first handle. The lower surface of the first retaining disc is fixedly connected with multiple groups of first arc rods in an equally spaced circular array. The center of the lower surface of the first retaining disc is fixedly connected with a threaded sleeve, and the inner wall of the threaded sleeve is provided with a threaded groove.

[0011] By adopting the above technical solution, multiple groups of first arc rods can cooperate with the second arc rods for connection and limitation. The threaded connection between the threaded sleeve and the rotating cylinder can facilitate moving the distance between the first retaining disc and the second retaining disc.

[0012] Further, the upper surface of the second retaining disc is fixedly connected with multiple groups of second arc rods in an equally spaced circular array, and the second arc rods are matched with the first arc rods.

[0013] By adopting the above technical solution, multiple groups of first arc rods can cooperate with the second arc rod to connect and limit the first retaining disc and the second retaining disc.

[0014] Furthermore, a rotating cylinder is fixedly connected to the center position of the upper surface of the rotating ring, and the outer wall of the rotating cylinder is in a threaded socket connection with the inner wall of the threaded sleeve.

[0015] By adopting the above technical solution, when rotating the rotating ring, it can drive the rotating cylinder to cooperate with the threaded sleeve to quickly adjust the distance between the first retaining disc and the second retaining disc.

[0016] Furthermore, a second handle is fixedly connected to the curved side wall of the rotating ring.

[0017] By adopting the above technical solution, the first handle and the second handle can facilitate the holding and rotation of the rotating ring of the device.

[0018] Furthermore, perforations of the same size are provided at the center positions of the first retaining disc, the rotating disc, the second retaining disc and the rotating ring.

[0019] By adopting the above technical solution, the perforation can pass through the rotating shaft rod of the driving device, facilitating subsequent installation and use.

[0020] In summary, the main beneficial effects of the present utility model are as follows:

[0021] The present utility model first twists and removes the fixing bolts, then rotates the rotating disc. At this time, the inner wall of the card hole disengages from the inside of the card slot. Then, the first retaining disc and the rotating disc as a whole are moved upward. At this time, multiple groups of telescopic rods are pulled out from the through holes, and finally the rapid disassembly of the device is completed. The above operations can be reversed to complete the rapid installation, improving the disassembly and assembly efficiency of the device. Secondly, the device is threadedly connected by the rotating cylinder and the threaded sleeve. First, hold the first handle and the second handle with both hands, and then rotate the second handle and the rotating ring.
