Description

Technical Field

[0001] This utility model relates to the field of die casting production technology, specifically a cooling device for thermoformed die castings. Background Technology

[0002] In the production of hot-formed die-cast parts, the cooling process of high-temperature castings directly affects product quality and production efficiency. Hanging air cooling (also known as suspended air cooling or suspended air cooling) is a method of cooling die-cast parts suspended on a conveyor chain or hanger using natural convection or forced ventilation (fans). Although its cooling rate is generally slower than water cooling, it is relatively low-cost, simple to operate, and results in less deformation. Therefore, for hot-formed die-cast parts with through holes or slots, hanging air cooling is usually the preferred method.

[0003] Existing air-cooling systems typically employ fixed suspension or unidirectional linear conveying, with parts moving statically or in a single direction on the hanger. However, the fixed posture of the parts limits the airflow surface, causing a sharp drop in heat dissipation efficiency in leeward areas, complex internal cavities, and thickness-to-thickness junctions. This results in uneven cooling and deformation of the parts. Solving this problem requires human intervention, with personnel periodically turning the parts over. This reduces production efficiency and increases the labor intensity of the workers. Utility Model Content

A pair of discs 15 are rotatably mounted on the inner rings of the fixed rings 4. The side surfaces of the discs 15 are connected to the inner rings of the fixed rings 4 via sliding parts.

The lower end of the main shaft 12 is fixedly connected to the output end of the motor 17, and the upper end is rotatably connected to the top of the housing 18. At least three support shafts 6 are arranged in a circular matrix and rotatably pass through the discs 15. The support shafts 6 are connected by a shaft... The support 8 is rotatably connected to the disc 15 and a gear 3 is fixedly connected to its lower end.

Multiple hangers 7 are evenly arranged on the support shaft 6. The fan 14 is located on the side surface of the housing 18 and can actively ventilate. Exhaust vents 10 are opened on the upper disc 15 and the top of the housing 18. The sliding component includes a sliding groove 9 and multiple sliders 11. The multiple sliders 11 are evenly and fixedly arranged on the side surface of the disc 15. The circumferential groove 9 is formed on the inner ring of the fixing ring 4, and the slider 11 is slidably connected to the circumferential groove 9; a wind equalization plate 5 is provided in the box 18 corresponding to the position of the fan 14, and a plurality of ventilation holes 13 are evenly opened on the wind equalization plate 5; the walking system 1 adopts a transport robot; at least three fans 14 are provided and evenly arranged on the side surface of the box 18; a gear 3 is fixedly connected to the upper end of the support shaft 6, and a gear ring 16 with internal teeth is coaxially provided on the top of the fixing ring 4 above, and the gear 3 meshes with the gear ring 16.

[0020] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, as follows:

[0021] According to the instruction manual Figure 1-3It can be seen that the walking system 1 moves the device to the die-casting equipment and turns on the fan 14. The fan 14 is a type with its own motor 17, which can perform ventilation operations. Personnel open the box door 19 and hang the die-casting parts on the hanger 7 of the support shaft 6. Here, for die-casting parts that can be hung, the motor 17 can also be turned on at this time. The motor 17 is a type of motor with its own reducer. The power supply and control system 2 can provide power to the fan 14 and the motor 17 and control them, which is the existing technology. The die-cast parts are on the hanger 7. The motor 17 drives the main shaft 12 to rotate, and the main shaft 12 drives the disc 15 to rotate within the fixed ring 4. The disc 15 drives at least three support shafts 6 to rotate. The hanger 7 on the support shaft 6 and the parts on the hanger 7 can rotate around the main shaft 12, or they can revolve. Since the lower end of the support shaft 6 is equipped with a gear 3, the gear 3 meshes with the gear ring 16 at the bottom of the fixed ring 4. When the support shaft 6 rotates with the disc 15, under the action of the gear ring 16, the gear 3 and the support shaft 6 can rotate around their axis, so that the parts on the hanger 7 rotate around the support shaft 6, or they can rotate on their own axis. The fan 14 blows air for cooling, and the air is discharged from the exhaust port 10 opened on the top of the disc 15 and the box 18. In this invention, the motor 17 drives the disc 15 to rotate, thereby causing multiple support shafts 6 and parts on the hanger 7 to revolve around the main shaft 12. Through the cooperation of the gear 3 at the lower end of the support shaft 6 and the gear ring 16, the parts can also rotate around the support shaft 6 while revolving, so that both sides of the parts can be exposed to wind, and the movement within the housing 18 is regular, the wind is evenly distributed, deformation is reduced, no manual intervention is required, and the degree of automation is high.

[0022] The sliding component includes a sliding groove 9 and multiple sliders 11. The multiple sliders 11 are evenly and fixedly arranged on the side surface of the disc 15. The sliding groove 9 is opened in the inner ring of the fixing ring 4 in the circumferential direction. The sliders 11 are slidably connected to the sliding groove 9 to ensure the stability of the disc 15, the support shaft 6, the hanger 7 and the parts on the hanger 7 when they rotate.

[0023] Inside the housing 18, a wind equalization plate 5 is provided at the position corresponding to the fan 14. Multiple ventilation holes 13 are evenly opened on the wind equalization plate 5. The air from the fan 14 is more even after passing through the wind equalization plate 5, so that the parts are subjected to more even airflow.

[0024] Among them, the walking system 1 adopts a transport robot for automatic transport and can perform cooling operations during transport, thereby improving work efficiency and automation.

[0025] Among them, at least three fans 14 are evenly distributed on the side surface of the housing 18 to improve cooling efficiency.

[0026] Among them, a gear 3 is fixedly connected to the upper end of the support shaft 6, and a gear ring 16 with internal teeth is coaxially arranged on the top of the upper fixing ring 4. The gear 3 meshes with the gear ring 16 to further ensure the stability of the disc 15, the support shaft 6, the hanger 7 and the parts on the hanger 7 when they rotate.
