Technical Field

[0001] This utility model relates to the field of automotive parts manufacturing technology, and in particular to a cooling mechanism for automotive die-casting parts production. Background Technology

[0002] Automotive die-cast parts remain at high temperatures after demolding and require cooling equipment to facilitate assembly. However, most existing cooling equipment is too simple in structure and has low cooling efficiency, requiring improvement.

[0003] Chinese Patent No. CN222725438U discloses a cooling mechanism for automobile die casting production. This device improves the cooling efficiency of die castings by setting an annular block outside the conveyor belt and a cooling fan that can move on the side wall of the annular block to dissipate heat from multiple angles.

[0004] However, the device still has shortcomings: when cooling the casting, if all points of the casting need to be cooled, the casting needs to be moved intermittently. After each movement, the cooling fan needs to be driven to rotate for one cycle. The overall cooling efficiency of the workpiece is low, and the device is difficult to take into account the side of the casting that is in contact with the conveyor belt. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a cooling mechanism for automobile die casting production.

[0006] The technical solution of this utility model is: a cooling mechanism for automobile die casting production, including a frame, a conveyor belt arranged on the frame, the conveyor belt being a mesh breathable belt, and a drive component for driving the conveyor belt to run on the frame.

[0009] And a fan, which is mounted on the frame. The output end of the fan is connected to the annular groove. When the fan is working, it blows air into the bend, and when the bend is blowing air out, it drives the annular plate to rotate around its axis.

[0010] Preferably, a drive roller and a driven roller are respectively provided at both ends of the frame, the drive roller and the driven roller are connected by a conveyor belt, and a support roller for supporting the load-bearing end of the conveyor belt is provided on the frame.

[0011] Preferably, the drive assembly includes pulley A, pulley B, a synchronous belt, and a motor. Pulley A is coaxially connected to the roller shaft of the drive roller. A rotating shaft is provided on the frame. Pulley B is coaxially connected to the rotating shaft. Pulley A and pulley B are connected by a synchronous belt drive. The motor body is connected to the frame, and the output end of the motor is connected to the rotating shaft.

[0012] Preferably, a bearing is provided inside the opening of the annular groove, and the bearing body is connected to the air guide pipe, while the movable part of the bearing is connected to the annular plate.

[0013] Preferably, the outlets of the bends are offset from the axial and radial directions of the air duct and tilted toward the end of the air duct away from the annular groove, and each bend is equipped with a pressure equalization valve to maintain stable gas pressure in the pipeline.

The heat-conducting rod is connected to a heat dissipation fin. The heat dissipation fin is located outside the temperature control chamber. A heat sink is installed on the frame to assist the heat dissipation fin in heat dissipation.

[0017] Compared with the prior art, the present invention has the following beneficial technical effects:

[0018] By installing an air guide duct with an annular groove and a rotating annular plate at the opening of the groove, and placing a bend in the duct on the annular plate, the reaction force of the airflow automatically rotates the annular plate when air is ejected from the bend, thus providing 360-degree airflow to the die-cast parts during the conveyor belt transmission process, improving their cooling efficiency.

[0024] Example 1

[0025] like Figures 1-3 As shown, this utility model proposes a cooling mechanism for automobile die-casting production, including a frame 1, an air duct 7, an annular plate 9, and a fan 12. A conveyor belt 2, which is a mesh-like permeable belt, is mounted on the frame 1. A drive assembly 5 for driving the conveyor belt 2 is mounted on the frame 1. A driving roller 3 and a driven roller 4 are respectively mounted at both ends of the frame 1, and the driving roller 3 and driven roller 4 are connected by the conveyor belt 2. A support roller 6 for supporting the load-bearing end of the conveyor belt 2 is also mounted on the frame 1. The drive assembly 5 includes a pulley A, a pulley B, a synchronous belt, and a motor. Pulley A is coaxially connected to the roller shaft of the driving roller 3. A rotating shaft is mounted on the frame 1, and pulley B is coaxially connected to the rotating shaft. Pulley A and pulley B are connected by the synchronous belt. The motor body is connected to the frame 1, and the motor output end is connected to the rotating shaft. A guide duct 7 is mounted on the frame 1 and surrounds the outside of the conveyor belt 2, allowing the conveyor belt 2 to carry the die-casting part through the guide duct 7. An annular groove 701 is coaxially formed on the inner wall of one end of the guide duct 7. An annular plate 9 is positioned at the opening of the annular groove 701 and is rotatably connected to the guide duct 7 coaxially. A bearing 8 is positioned inside the opening of the annular groove 701, with its body connected to the guide duct 7 and its movable part connected to the annular plate 9. Several bends 10 are arranged in a circular array on the annular plate 9. The outlets of the bends 10 are offset from the axial and radial directions of the guide duct 7 and tilted towards the end of the guide duct 7 away from the annular groove 701. Each bend 10 is equipped with a pressure equalization valve to maintain stable gas pressure within the pipe. An air inlet pipe 11 is provided on the guide duct 7, communicating with the interior of the annular groove 701. The fan 12 is mounted on the frame 1. The output end of the fan 12 is connected to the air inlet pipe 11. When the fan 12 is working, it sends air to the bend pipe 10, and when the bend pipe 10 is discharging air, it drives the annular plate 9 to rotate around its axis.

[0026] In this embodiment, the die-cast part is placed on the conveyor belt 2, and the motor drives the pulley B to rotate, thereby driving the pulley A and the drive shaft 3 to rotate through the synchronous belt, which in turn drives the conveyor belt 2 to run. The die-cast part moves from one end of the air guide pipe 7 away from the bend pipe 10 to the other end. During this process, the fan 12 is started and blows air into the annular groove 701. The bend pipe 10 blows air and, at the same time, the reaction force of the jet airflow drives the annular plate 9 to rotate. The rotating annular plate 9 causes the bend pipe 10 to continuously change the blowing angle, thereby achieving 360-degree airflow without dead angles on the die-cast part, so that the die-cast part is cooled evenly and its cooling efficiency is improved.

[0027] Example 2

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, the present invention proposes a cooling mechanism for automobile die-casting production. Compared with Embodiment 1, a temperature control chamber 13 is installed on the frame 1. An air filter 14 is installed at the input end of the temperature control chamber 13, and the output end of the temperature control chamber 13 is connected to the input end of the fan 12. Several partitions 15 are staggered inside the temperature control chamber 13 to form a serpentine channel. The input ends of the air filter 14 and the fan 12 are located at the two ends of the serpentine channel, respectively. A semiconductor cooler 16 is installed on the temperature control chamber 13. The cold end of the semiconductor cooler 16 is inserted into the serpentine channel, and the hot end of the semiconductor cooler 16 is connected to a heat-conducting rod. The heat-conducting rod is connected to a heat dissipation fin 17. The heat dissipation fin 17 is located outside the temperature control chamber 13, and a radiator is installed on the frame 1 to assist the heat dissipation fin 17 in heat dissipation.

[0029] In this embodiment, when the fan 12 is in operation, outside air enters the serpentine channel after being filtered by the air filter element 14. Subsequently, the air exchanges heat with the cold end of the semiconductor cooler 16, and the air temperature decreases. The lower temperature air enters the annular groove 701 and is blown towards the die-casting part by the bend pipe 10, further improving the cooling efficiency of the die-casting part.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
