Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning system cleaning technology, specifically a cleaning mold assembly for automotive air conditioning system repair. Background Technology

[0002] When a car's air conditioning is in cooling mode, the heat pump system absorbs heat from inside the vehicle and transfers it to the outside. In this mode, the heat pump radiator acts like the condenser in a traditional air conditioning system. The refrigerant absorbs heat from the vehicle's interior in the evaporator, becoming a high-temperature, high-pressure gas, which then flows into the heat pump radiator. Inside the radiator, the high-temperature, high-pressure gaseous refrigerant exchanges heat with the outside air, dissipating heat to the surrounding environment while gradually cooling and liquefying into liquid refrigerant. Existing automotive air conditioning system cleaning kits on the market work by connecting the heat pump radiator to a cleaning plate. A water pump then pumps cleaning fluid into the cleaning plate, which in turn enters the heat pump radiator to clean its internal pipes and cooling fins. This cleaning method effectively removes dirt from inside the radiator and restores its heat exchange capabilities.

[0003] Existing heat pump radiators and cleaning plates are typically connected by bolts, such as... Figure 1 As shown. During each cleaning operation, operators need to precisely align the bolt holes on the cleaning plate with the bolt holes on the heat pump radiator to install the bolts. This process is not only cumbersome but also time-consuming and labor-intensive. Furthermore, in existing cleaning mold assemblies, each cleaning plate can only be connected to one size of heat pump radiator because the size, shape, and interface location of heat pump radiators vary in different car air conditioning systems. Utility Model Content

[0004] The purpose of this invention is to provide a cleaning mold assembly for automotive air conditioning system repair, addressing the problem mentioned in the background section that existing heat pump radiators and cleaning plates are typically connected by bolts. During each cleaning operation, operators need to precisely align the bolt holes on the cleaning plate with the bolt holes on the heat pump radiator to complete the bolt installation. This process is not only cumbersome but also time-consuming and labor-intensive. Furthermore, in existing cleaning mold assemblies, one cleaning plate can only be connected to one size of heat pump radiator because the size, shape, and interface position of heat pump radiators vary in different automotive air conditioning systems.

[0005] To solve the above problems, this utility model provides the following technical solution: a cleaning mold assembly for automotive air conditioning system repair, comprising a cleaning plate and a limiting part:

[0006] The cleaning plate has two sets of conveying pipes inside. The cleaning plate has an inlet a and an outlet a inside, and an outlet a and an inlet b inside. The limiting part is located at the top of the cleaning plate. The limiting part has a slider that is slidably installed on the top of the cleaning plate. A pressure rod is rotatably installed on the top of the slider. The pressure rod abuts against the edge of the heat pump radiator. The pressure rod rotates to press the heat pump radiator. A connecting block is slidably installed on the top of the cleaning plate. A connecting bolt is installed on the top of the connecting block. The pressure rod is connected to the connecting block through the connecting bolt.

[0007] By adopting the above technical solution, cleaning media such as cleaning fluid can be delivered into the cleaning plate through inlet a and inlet b. After cleaning the heat pump radiator through two sets of delivery pipes, the cleaning media is discharged from outlet a and outlet b. At the same time, by utilizing the sliding of the slider, the rotation of the pressure rod, and the cooperation of the connecting block and connecting bolts, heat pump radiators of different sizes can be easily fixed and limited, allowing them to be stably placed on the cleaning plate for cleaning operations.

[0008] Preferably, the cleaning plate also has a groove a formed on the top of the cleaning plate, and the slider is embedded in the groove a and is laterally slidably connected to the cleaning plate.

[0009] By adopting the above technical solution, the slider can be flexibly slid laterally in the slide groove a according to the size of the heat pump radiator, and the position of the slider can be adjusted so that the pressure rod can accurately abut against the edge of the heat pump radiator, thereby achieving adaptability and fixation for heat pump radiators of different specifications.

[0010] Preferably, the cleaning plate also has a groove b formed on the top of the cleaning plate, and the connecting block is embedded in the groove b and slidably connected to the cleaning plate laterally.

[0011] By adopting the above technical solution, after the slider position is adjusted, the connecting block can slide laterally in the slide groove b, so that the position of the connecting block matches the position of the pressure rod, making it easy to connect the pressure rod and the connecting block with connecting bolts, and further enhancing the fixing effect on the heat pump radiator.

[0012] Preferably, the cleaning plate also has a rubber pad embedded on the top of the cleaning plate, which abuts against the bottom of the heat pump radiator.

[0013] By adopting the above technical solution, the elasticity of the rubber pad can be used to cushion the heat pump radiator when it is placed on the cleaning plate, preventing damage caused by direct rigid contact between the heat pump radiator and the cleaning plate. At the same time, the rubber pad can also increase the friction between the heat pump radiator and the cleaning plate, making the heat pump radiator more stable.

[0014] Preferably, the rubber pad has an opening inside that is connected to the inlet a, outlet a, inlet b and outlet b.

[0015] By adopting the above technical solution, it can be ensured that cleaning fluid and other cleaning media can smoothly pass through the openings on the rubber pad, flow into the cleaning plate from inlet a and inlet b to clean the heat pump radiator, and then flow out from outlet a and outlet b, ensuring the normal progress of the cleaning operation.

[0016] Preferably, the limiting part also has a rotating groove formed on the top of the slider, and one end of the pressure rod is provided with a rotating shaft, which is embedded in the rotating groove and rotatably connected to the slider. There are four sliders.

[0017] By adopting the above technical solution, the pressure rod can be easily rotated to a position that abuts against the edge of the heat pump radiator by rotating the shaft in the rotating groove, thereby achieving rapid fixation of the heat pump radiator.

[0018] Preferably, the limiting part also has a threaded groove on the top of the connecting block, and a through hole is provided at the end of the pressure rod away from the slider. The connecting bolt passes through the pressure rod and is threadedly connected to the threaded groove.

[0019] By adopting the above technical solution, after the pressure rod is rotated to a suitable position, the connecting bolt can be passed through the through hole of the pressure rod and threadedly connected to the threaded groove on the top of the connecting block, thereby firmly fixing the pressure rod to the connecting block.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: By setting a limiting part, cleaning medium such as cleaning fluid can be delivered into the cleaning plate through inlet a and inlet b. After cleaning the heat pump radiator through two sets of delivery pipes, the cleaning medium is discharged from outlet a and outlet b. At the same time, by utilizing the sliding of the slider, the rotation of the pressure rod, and the cooperation of the connecting block and connecting bolts, heat pump radiators of different sizes can be easily fixed and limited, so that they are stably placed on the cleaning plate for cleaning operations.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1

[0030] Please see Figure 2 , Figure 3 and Figure 4 This embodiment provides a technical solution: a cleaning mold assembly for automotive air conditioning system repair, comprising a cleaning plate 1 and a limiting part 2.

[0031] The cleaning plate 1 has two sets of delivery pipes inside. The cleaning plate 1 has an inlet a104 and an outlet a105, and an outlet a105 and an inlet b106. A rubber pad 103 is embedded in the top of the cleaning plate 1, abutting against the bottom of the heat pump radiator. The elasticity of the rubber pad 103 acts as a buffer when the heat pump radiator is placed on the cleaning plate 1, preventing direct rigid contact and damage. Simultaneously, the rubber pad 103 increases the friction between the heat pump radiator and the cleaning plate 1, making the heat pump radiator more stable.

[0032] The rubber pad 103 has openings inside and is connected to the inlet a104, outlet a105, inlet b106 and outlet b107. This ensures that cleaning fluid and other cleaning media can pass smoothly through the openings on the rubber pad 103, flow into the cleaning plate 1 from the inlet a104 and inlet b106 to clean the heat pump radiator, and then flow out from the outlet a105 and outlet b107, ensuring the normal progress of the cleaning operation.

[0033] A limiting part 2 is located on the top of the cleaning plate 1. The limiting part 2 has a slider 201 slidably mounted on the top of the cleaning plate 1. A pressure rod 203 is rotatably mounted on the top of the slider 201. The pressure rod 203 abuts against the edge of the heat pump radiator. The pressure rod 203 rotates to press down on the heat pump radiator. A connecting block 205 is slidably mounted on the top of the cleaning plate 1. A connecting bolt 207 is mounted on the top of the connecting block 205. The pressure rod 203 is connected to the connecting block 205 through the connecting bolt 207. Cleaning medium such as cleaning fluid can be delivered into the cleaning plate 1 through the inlet a104 and the inlet b106. After cleaning the heat pump radiator through two sets of delivery pipes, the cleaning medium is discharged from the outlet a105 and the outlet b107. At the same time, by utilizing the sliding of the slider 201, the rotation of the pressure rod 203, and the cooperation of the connecting block 205 and the connecting bolt 207, heat pump radiators of different sizes can be easily fixed and limited, so that they are stably placed on the cleaning plate 1 for cleaning operations.

[0034] Example 2

[0035] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a cleaning mold assembly for automotive air conditioning system repair, comprising a cleaning plate 1 and a limiting part 2.

[0036] A groove a101 is provided on the top of the cleaning plate 1. The slider 201 is embedded in the groove a101 and is slidably connected to the cleaning plate 1 laterally. The slider 201 can be flexibly slid laterally in the groove a101 according to the size of the heat pump radiator, and the position of the slider 201 can be adjusted so that the pressure rod 203 can accurately abut against the edge of the heat pump radiator, thereby achieving adaptability and fixation for heat pump radiators of different specifications.

[0037] A groove b102 is provided on the top of the cleaning plate 1. The connecting block 205 is embedded in the groove b102 and is slidably connected to the cleaning plate 1. After the slider 201 is adjusted, the connecting block 205 can be slid laterally in the groove b102 to match the position of the connecting block 205 with the pressure rod 203. This makes it easy to connect the pressure rod 203 and the connecting block 205 with the connecting bolt 207, further enhancing the fixing effect on the heat pump radiator.

[0038] A rotating groove 202 is provided on the top of the slider 201. A rotating shaft 204 is provided at one end of the pressure rod 203. The rotating shaft 204 is embedded in the rotating groove 202 and is rotatably connected to the slider 201. There are four sliders 201. The pressure rod 203 can be easily rotated to a position that abuts against the edge of the heat pump radiator by rotating the rotating shaft 204 in the rotating groove 202, so as to quickly fix the heat pump radiator.

[0039] A threaded groove 206 is provided on the top of the connecting block 205, and a through hole is provided at the end of the pressure rod 203 away from the slider 201. The connecting bolt 207 passes through the pressure rod 203 and is threadedly connected to the threaded groove 206. After the pressure rod 203 is rotated to a suitable position, the connecting bolt 207 can be passed through the through hole of the pressure rod 203 and threadedly connected to the threaded groove 206 on the top of the connecting block 205, thereby firmly fixing the pressure rod 203 to the connecting block 205.

[0040] Working principle: First, according to the size of the heat pump radiator, slide the slider 201 laterally in the groove a101 on the top of the cleaning plate 1 to adjust the slider 201 to a suitable position so that the pressure rod 203 roughly corresponds to the edge of the heat pump radiator. Next, place the heat pump radiator on the rubber pad 103 on the top of the cleaning plate 1. Utilize the cushioning effect and friction-increasing properties of the rubber pad 103 to initially stabilize the heat pump radiator. Then, by rotating the shaft 204 in the rotating groove 202 on the top of the slider 201, rotate the pressure rod 203 until it abuts against the edge of the heat pump radiator, achieving initial fixation of the heat pump radiator. Afterward, slide the connecting block 205 laterally in the groove b102 on the top of the cleaning plate 1 so that the position of the connecting block 205 matches the position of the through hole at the end of the pressure rod 203 away from the slider 201. Finally, insert the connecting bolt 207. The pressure rod 203 passes through the through hole and is threaded into the threaded groove 206 on the top of the connecting block 205, thereby firmly fixing the pressure rod 203 onto the connecting block 205 and completing the stable fixation of the heat pump radiator. At this time, the four sliders 201 and the corresponding pressure rods 203 limit the heat pump radiator from multiple directions, ensuring that it is firmly placed on the cleaning plate 1. Finally, cleaning fluid and other cleaning media are delivered into the cleaning plate 1 from the inlet a104 and the inlet b106. The cleaning media cleans the heat pump radiator through the two sets of delivery pipes inside the cleaning plate 1. The cleaned media is discharged from the outlet a105 and the outlet b107, realizing the cleaning operation of the heat pump radiator of the automotive air conditioning system. After cleaning, the above steps are reversed, the connecting bolts 207 are loosened, and the pressure rod 203 is rotated to remove the cleaned heat pump radiator from the cleaning plate 1.
