[0002] Fins are an indispensable part of air conditioners and other refrigeration equipment, primarily enhancing heat exchange and improving heat dissipation efficiency. The molds used for fin production need to meet high precision and high efficiency requirements. Air conditioner heat exchanger fins increase heat exchange efficiency by increasing surface area; common fin structures include corrugated and honeycomb types. Fin design must balance thermal conductivity and airflow resistance to ensure optimal heat exchange performance.

[0003] Although existing technologies use production molds to process and transport fins, the specifications of the fins are different, and existing production equipment cannot meet the problem of producing fins of different specifications, resulting in reduced production efficiency. Therefore, those skilled in the art provide a mold for producing air conditioning heat exchanger fins to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to provide a mold for producing air conditioner heat exchanger fins that is simple in structure and reasonably designed in order to solve the above problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A mold for producing air conditioner heat exchanger fins includes a support frame. A second bidirectional lead screw is rotatably connected to the middle of the top of the support frame. Limiting rods are fixedly connected to both sides of the top of the support frame. A rotating handle is fixedly connected to one end of the second bidirectional lead screw. Driving devices that cooperate with the two limiting rods are respectively provided on both sides of the second bidirectional lead screw. Limiting devices are respectively provided at the top of the two driving devices. Conveying devices are respectively provided inside the two limiting devices.

[0007] As a further optimization of this utility model, the driving device includes a slider that is threadedly connected to the side wall of the second bidirectional lead screw, and the two sides of the slider are slidably connected to the side walls of two limit rods respectively. A mounting bracket is fixedly connected to the front end of the slider, and a first servo motor is fixedly connected to one side of the mounting bracket. A rotating shaft that is rotatably connected to the inner wall of the mounting bracket is fixedly connected to the output end of the first servo motor.

[0008] As a further optimization of this utility model, the limiting device includes a fixed frame fixedly connected to the top of the slider. Three first bidirectional lead screws are rotatably connected to the inner wall of the fixed frame. The bottom ends of the three first bidirectional lead screws respectively rotatably pass through the bottom end of the inner wall of the fixed frame and are fixedly connected to the middle of three driven helical gears. Slide plates are threadedly connected to both sides of the three first bidirectional lead screws. Several stabilizing mechanisms are provided between two slide plates.

[0009] As a further optimization of this utility model, the stabilizing mechanism includes a support rod fixedly connected to the slide plate, and a ball bearing is rotatably connected to one end of the support rod.

[0010] As a further optimization of this utility model, the conveying device includes an electric telescopic rod fixedly connected to the inner wall of the fixed frame, an adjusting frame fixedly connected to the output end of the electric telescopic rod, and sliding rods fixedly connected to both sides of the rear end of the adjusting frame. Sleeves are slidably sleeved on the side walls of the two sliding rods, and the other ends of the two sleeves are fixedly connected to the inner wall of the fixed frame. A power mechanism is provided on the inner wall of the adjusting frame.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, by setting a driving device and a limiting device, the first servo motor drives the rotating shaft to rotate, thereby driving the transmission helical gear to rotate, which in turn drives the driven helical gear to rotate the first bidirectional lead screw, thereby adjusting the distance between the two slide plates. This allows the balls in the support rods located on the two slide plates to contact the top and bottom of the workpiece respectively, achieving stable support for the workpiece. Since the support rods are equipped with balls, the friction of the workpiece during transportation is reduced, improving the stability of transportation.

It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0022] Example 1

[0023] like Figure 1 , Figure 2As shown, a mold for producing air conditioner heat exchanger fins includes a support frame 4. A second bidirectional lead screw 7 is rotatably connected to the top center of the support frame 4. Limiting rods 5 are fixedly connected to both sides of the top of the support frame 4. A rotating handle 6 is fixedly connected to one end of the second bidirectional lead screw 7. Driving devices 1 that cooperate with the two limiting rods 5 are respectively provided on both sides of the second bidirectional lead screw 7. Limiting devices 2 are respectively provided at the top of the two driving devices 1. Conveying devices 3 are respectively provided inside the two limiting devices 2. According to the specifications of the air conditioner heat exchanger fin workpiece, rotating the rotating handle 6 causes the second bidirectional lead screw 7 to rotate, adjusting the distance between the two sliders 101 so that the two sides of the workpiece are respectively located in the middle of the two limiting devices 2, facilitating the conveying of the workpiece.

[0024] like Figure 1 , Figure 2 and Figure 3 As shown, a slider 101 is threadedly connected to the side wall of the second bidirectional lead screw 7, and the two sides of the slider 101 are slidably connected to the side walls of the two limit rods 5 respectively. A mounting bracket 103 is fixedly connected to the front end of the slider 101. A first servo motor 102 is fixedly connected to one side of the mounting bracket 103. A rotating shaft 106 is fixedly connected to the output end of the first servo motor 102 and rotatably connected to the inner wall of the mounting bracket 103. Three transmission helical gears 104 are fixedly connected to the side wall of the rotating shaft 106. Driven helical gears 105 are meshed on the side walls of the three transmission helical gears 104 respectively. The first servo motor 102 drives the rotating shaft 106 to rotate, so that the rotating shaft 106 can drive the transmission helical gears 104 to rotate, so that the driven helical gears 105 can drive the first bidirectional lead screw 205 to rotate, thereby adjusting the distance between the two sliding plates 204.

[0025] like Figure 2 , Figure 5 As shown, a fixed frame 201 is fixedly connected to the top of the slider 101. Three first bidirectional lead screws 205 are rotatably connected to the inner wall of the fixed frame 201. The bottom ends of the three first bidirectional lead screws 205 respectively rotatably pass through the bottom end of the inner wall of the fixed frame 201 and are fixedly connected to the middle of three driven helical gears 105. Slide plates 204 are threadedly connected to both sides of the three first bidirectional lead screws 205. Support rods 203 are fixedly connected to the slide plates 204. One end of the support rod 203 is rotatably connected to a ball bearing 202. The ball bearings 202 in the support rods 203 on the two slide plates 204 respectively contact the top and bottom ends of the workpiece to achieve stable support for the workpiece. Since the support rods 203 are equipped with ball bearings 202, the friction of the workpiece during conveying can be reduced, thereby improving the stability of the conveying.

[0026] like Figure 4As shown, an electric telescopic rod 301 is fixedly connected to the inner wall of the fixed frame 201. An adjusting frame 306 is fixedly connected to the output end of the electric telescopic rod 301. Slide rods 308 are fixedly connected to both sides of the rear end of the adjusting frame 306. Sleeves 307 are slidably sleeved on the side walls of the two slide rods 308, and the other ends of the two sleeves 307 are fixedly connected to the inner wall of the fixed frame 201. When the two slide plates 204 clamp and fix the two workpieces respectively, the workpieces can be processed. After processing, the extension and retraction of the electric telescopic rod 301 makes the surface of the belt 304 contact the two sides of the workpiece.

[0027] like Figure 4 As shown, a transmission pulley 303 is rotatably connected to one side of the inner wall of the adjusting frame 306, and a second servo motor 302 is fixedly connected to one side of the top of the adjusting frame 306. The output end of the second servo motor 302 rotatably passes through the top of the adjusting frame 306 and is fixedly connected to the middle of the transmission pulley 303. A driven pulley 305 is rotatably connected to the other side of the inner wall of the adjusting frame 306. A belt 304 that mates with the side wall of the driven pulley 305 is provided on the side wall of the transmission pulley 303. The second servo motor 302 drives the transmission pulley 303 to rotate, so that the belt 304 can move the workpiece, realizing the conveying of the processed workpiece, effectively improving the automation of the air conditioner heat exchanger production and increasing production efficiency.

[0028] It should be noted that, in use, this mold for producing air conditioner heat exchanger fins involves rotating the handle 6 according to the specifications of the air conditioner heat exchanger fin workpiece, causing the second bidirectional lead screw 7 to rotate, adjusting the distance between the two sliders 101 so that the two sides of the workpiece are respectively located in the middle of the two limiting devices 2. The first servo motor 102 drives the rotating shaft 106 to rotate, which in turn drives the transmission helical gear 104 to rotate, causing the driven helical gear 105 to drive the first bidirectional lead screw 205 to rotate, thereby adjusting the distance between the two sliding plates 204. This allows the balls 202 in the support rods 203 on the two sliding plates 204 to contact the top and bottom ends of the workpiece, respectively. When the two sliding plates 204 clamp and fix the two workpieces, the workpieces can be processed. After processing, the extension and retraction of the electric telescopic rod 301 causes the surface of the belt 304 to contact the two sides of the workpiece. At this time, the second servo motor 302 drives the transmission pulley 303 to rotate, allowing the belt 304 to move the workpiece, thus realizing the conveying of the processed workpiece.

[0029] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
