Description

Technical Field

[0001] This utility model relates to the technical field of automotive parts production equipment, specifically a cooling device for die-cast parts used in automotive parts production. Background Technology

[0002] In the production of automotive parts, the cooling process for die-cast parts is crucial. Existing cooling devices have numerous problems in practical applications, affecting production efficiency and product quality. For example, patent document No. 202222597794.7 discloses a cooling device for forged die-cast parts in automotive parts production. It uses a first water spray head on the top cover and a second water spray head on the inner wall of the water tank to initially cool various surfaces of the casting. Then, a slotted box is pulled into a water tank filled with cool water via ropes for comprehensive cooling. While this device can cool the casting to some extent, it has the following problems: First, the cooling process is relatively complex, requiring manual control of the rope-pulling of the slotted box, which is inconvenient and inefficient. Second, in the initial cooling stage, the water spray head has a limited cooling range on the casting, failing to achieve all-around cooling, potentially leading to uneven cooling and affecting product quality. Third, during the cooling process, the contact between the casting and the cooling device is not stable enough, and it is prone to loosening or falling off during movement, posing a safety hazard.

[0003] In summary, existing die-casting cooling devices suffer from problems such as low cooling efficiency, uneven cooling, and poor stability. There is an urgent need for a new type of cooling device that can effectively solve these problems in order to improve the quality and efficiency of automotive parts production.

[0014] (III) Beneficial Effects

[0015] This utility model provides a cooling device for die-cast parts in automotive parts production, which has the following advantages:

[0016] 1. This utility model achieves omnidirectional and continuous initial cooling of die-cast parts through the installation of a spray assembly and a driving component. The spray assembly has multiple nozzles on a rotating ring, allowing the nozzles to spray water onto the die-cast parts from all directions. Simultaneously, the driving component moves the fixing assembly along the length of the cooling tank, ensuring the die-cast parts are continuously cooled by the spray during movement, thus avoiding insufficient cooling caused by prolonged residence time on the placement platform. This omnidirectional and continuous water spray cooling method significantly improves the cooling efficiency of die-cast parts, shortens cooling time, and thereby improves the overall efficiency of automotive parts production.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0026] Please see Figures 1 to 4 The present invention provides a technical solution: a cooling device for die-cast parts used in the production of automotive parts, comprising a cooling tank 1, a drive component, and a primary cooling component.

[0027] The primary cooling component includes a spray assembly and two fixed assemblies. The two fixed assemblies are slidably mounted on the upper edges of the two side walls of the cooling tank 1, and the fixed assemblies move along the length of the cooling tank 1. A driving component is connected to the two fixed assemblies and drives the two fixed assemblies to slide.

[0028] The cooling tank 1 holds coolant, which can also be water. The initial cooling component provides preliminary cooling to the die-cast part 6. The spray assembly cools the high-temperature die-cast part 6 with spray. Two fixing components clamp and hold the die-cast part 6, and also serve as support for the spray assembly. The driving component drives the two fixing components to slide along the length of the cooling tank 1.

[0029] The fixing assembly includes a mounting block 7, an electric telescopic rod 16, and a connecting rod 17. The connecting rod 17 is slidably mounted on the upper edge of the side wall along the length of the cooling tank 1. One end of the mounting block 7 is fixedly connected to one end of the connecting rod 17. The electric telescopic rod 16 is embedded in the mounting block 7, and a clamping plate is fixedly connected to the output shaft end of the electric telescopic rod 16.

[0030] The mounting block 7 serves to support and secure other components. The electric telescopic rod 16 is used to extend and retract the clamping plate, thereby clamping and releasing the die-cast part. When the electric telescopic rod 16 is energized, the extension and retraction of its output shaft causes the clamping plate to move closer to or further away from the die-cast part 6, achieving the clamping and releasing function. By precisely controlling the extension and retraction stroke of the electric telescopic rod 16, it can be ensured that the clamping force of the clamping plate on the die-cast part 6 is uniform and stable, avoiding loosening or damage to the die-cast part due to insufficient or excessive clamping force. In actual implementation, a servo electric cylinder can also be used to level the electric telescopic rod 16. The clamping plate is made of high-temperature resistant material.

[0031] The spray assembly includes a ring 8 and multiple nozzles 5. The ring 8 is rotatably mounted on a connecting rod 17 in two fixed components. The interior of the ring 8 is hollow. Each nozzle 5 is fixedly mounted on the inner wall of the ring 8 and communicates with the interior of the ring 8. The spray assembly also includes a water inlet pipe 14 and a water pump. The water pump is fixedly mounted on the outside of the cooling tank 1, and the water inlet end of the water pump communicates with the interior of the cooling tank 1. One end of the water inlet pipe 14 is fixedly mounted to the outlet end of the water pump. The outlet end of the water inlet pipe 14 passes through the slider 3 and the connecting rod 17 in sequence, and communicates with the internal cavity of the ring 8.

[0032] The ring 8 is used to store and distribute coolant. The design of the ring 8 allows the coolant to be evenly distributed to each nozzle 5, achieving omnidirectional water spray cooling of the die-cast part 6. Through the rotation of the ring 8, the nozzles 5 can cover all surfaces of the die-cast part 6, ensuring that the coolant is sprayed evenly on the die-cast part 6 and avoiding uneven cooling. The nozzles 5 are used to evenly spray coolant onto the surface of the die-cast part 6, achieving initial cooling of the die-cast part 6. A water pump is used to extract coolant from the cooling tank 1 and transport it through the inlet pipe 14 to the internal cavity of the ring 8, providing a stable coolant supply to the nozzles 5.

[0033] Specifically, the fixing component also includes a slider 3, which is slidably mounted on the upper edge of the side wall along the length of the cooling tank 1, and the connecting rod 17 is fixedly connected to the slider 3.

[0034] The slider 3 is installed on the upper edge of the side wall of the cooling tank 1. Through the fixed connection with the connecting rod 17, the fixing components (including the mounting block 7, the electric telescopic rod 16, etc.) are firmly installed on the cooling tank 1.

[0035] Specifically, the spray assembly also includes two gears 15, which are respectively fitted on the outer side wall of the connecting rod 17, and the gears 15 are fixedly connected to the ring 8.

[0036] More specifically, the driving components include a reciprocating lead screw 2 and a motor 13. The motor 13 is fixedly mounted on the cooling tank 1, and the reciprocating lead screw 2 is rotatably mounted on the cooling tank 1. The reciprocating lead screw 2 passes through a slider 3 laterally and the two are threadedly connected. The motor 13 is connected to the reciprocating lead screw 2 in a transmission connection, and the motor 13 drives the reciprocating lead screw 2 to rotate.

[0037] More specifically, the drive component also includes a guide rod 12 and two racks 9. The guide rod 12 is fixedly installed on the cooling tank 1 and passes through another slider 3 laterally, with the two being slidably connected. Both racks 9 are fixedly installed on the cooling tank 1 and are arranged in parallel. The two racks 9 mesh with two gears 15 respectively.

[0038] The gear 15 is mounted on the outer wall of the connecting rod 17 and meshes with the rack 9 fixed to the cooling tank 1. When the slider 3 moves along the cooling tank 1, the rack 9 drives the gear 15 to rotate. The gear 15 is fixedly connected to the ring 8, so the rotation of the gear 15 will drive the ring 8 to rotate synchronously. This design allows the nozzles 5 on the ring 8 to spray water for cooling in all directions during the movement of the die-cast part, significantly improving cooling efficiency and cooling uniformity.

[0039] When motor 13 is powered on and started, its output drives the reciprocating screw 2 to rotate. The rotation of the reciprocating screw 2 is converted into linear motion of slider 3 through a threaded connection. When slider 3 moves, gear 15 fixed on it meshes with rack 9, driving gear 15 to rotate. The rotation of gear 15, through a fixed connection with ring 8, drives ring 8 to rotate synchronously. The speed and direction of rotation of motor 13 can be precisely controlled by a programmable logic controller, thereby achieving precise movement of slider 3. The working principle and control program of the programmable logic controller will not be elaborated further. The main function of guide rod 12 is to provide precise guidance for slider 3, ensuring that slider 3 maintains linear motion during movement, avoiding deviation or vibration, thereby improving the stability and reliability of the entire device. It also plays an auxiliary support role, enhancing the structural stability of slider 3.

[0040] Specifically, a placement platform 4 is fixedly installed at one end of the cooling tank 1.

[0041] The placement platform 4 provides a stable placement position for the die-casting part. Before the die-casting part is cooled, it is placed on the placement platform 4 to facilitate the clamping operation of the fixing components.

[0042] Specifically, a gantry frame 10 is fixedly installed on the cooling tank 1, and an electric hoist 11 is fixedly installed on the gantry frame 10. An ultra-high temperature electromagnet is suspended from the free end of the rope of the electric hoist 11.

[0043] The gantry frame 10 is a crucial support structure on the cooling tank 1, used to securely mount the electric hoist 11 and ensure its stability during operation. The ultra-high temperature electromagnet is suspended above the cooling tank 1 via ropes from the electric hoist 11. When it is necessary to lift the die-cast part 6, the electric hoist 11 lowers the ultra-high temperature electromagnet to the cooling tank 1. When energized, the electromagnet generates a strong magnetic field, attracting and holding the die-cast part 6. The electric hoist 11, by suspending the die-cast part 6 via the electromagnet, allows the die-cast part 6 to be moved into or out of the cooling tank 1. The die-cast part 6 is submerged in the coolant within the cooling tank 1, achieving final cooling.

[0044] In use, the high-temperature die-cast part is placed on the placement platform 4 at one end of the cooling tank 1. The placement platform 4 provides a stable placement position for the die-cast part, facilitating subsequent clamping operations.

[0045] Motor 13 starts, driving reciprocating screw 2 to rotate. Reciprocating screw 2 drives slider 3 to move along the length of cooling tank 1 through threaded connection until slider 3 reaches above the placement platform 4.

[0046] After slider 3 reaches the designated position, electric telescopic rod 16 is activated, its output shaft extends, and drives clamping plate closer to die-cast part 6 to complete the clamping action. The clamping plate is made of high-temperature resistant material to ensure stable operation in high-temperature environments.

[0047] Motor 13 continues to drive the reciprocating screw 2 to rotate, causing the slider 3 to move along the length of the cooling tank 1, moving the clamped die-cast part 6 to the designated position above the cooling tank 1.

[0048] During movement, the water pump starts, drawing coolant from the cooling tank 1 and delivering it to the internal cavity of the ring 8 through the inlet pipe 14. The coolant inside the ring 8 is sprayed out through the nozzles 5, providing all-around water cooling to the die-cast part 6. The ring 8 rotates through the meshing of the gear 15 and the rack 9, ensuring that the nozzles 5 can cover all surfaces of the die-cast part 6, achieving uniform cooling.

[0049] After the die-cast part 6 has completed its initial cooling, the electric hoist 11 is started, and the ultra-high temperature electromagnet is lowered into the cooling tank 1 via a rope. When the electromagnet is energized, it generates a strong magnetic field, which attracts and holds the die-cast part 6.

[0050] The electric hoist 11 slowly lowers the die-cast part 6 into the coolant in the cooling tank 1 via a rope, so that the die-cast part 6 is completely immersed in the coolant for final cooling.

[0051] After cooling is complete, the electromagnet is de-energized, the magnetic field disappears, and the die-cast part 6 is released. The electric hoist 11 then uses a rope to lift the electromagnet back to its standby position.

[0052] After cooling, the die-cast part is lifted out of the cooling tank 1 by the electric hoist 11 and placed at the unloading position at the end of the cooling tank 1 to complete the entire cooling process.
