Description

Technical Field

[0001] The invention relates to the technical field of die-casting processing cooling, and in particular to a cooling device for die-casting equipment of loom accessories. Background Art

[0002] Metal die-casting parts are usually produced continuously. After smelting, the molten metal is sent to the die-casting machine and filled into the die-casting machine for continuous die-casting, continuously producing metal die-casting parts. In the die-casting automated production line, the formed metal die-casting parts need to be cooled to facilitate subsequent processing.

[0003] For example, the Chinese patent publication number CN205270805U discloses an air cooling device for aluminum alloy die-castings, which includes a frame, a heat preservation cover, a conveyor belt and an exhaust fan. A horizontal conveyor belt is provided on the top of the frame, and the conveyor belt is a metal mesh conveyor belt. The surface of the conveyor belt is evenly distributed with a number of metal horizontal bars. A heat preservation cover is provided in the middle of the conveyor belt, and the heat preservation cover has openings only on the left and right sides. A fan is provided on the front side of the heat preservation cover, and a protective cover is provided on the fan. A digital thermometer is provided in the middle of the front side of the heat preservation cover, and the temperature measuring component of the digital thermometer is provided inside the heat preservation cover. In addition, a collection trough is provided at the bottom of the frame, and a metal mesh is provided above the collection trough; an air suction hood is provided on the rear side of the heat preservation cover corresponding to the fan.

[0004] However, the above patent has some shortcomings. During the air cooling process of the die-casting after heat treatment, the die-casting will come into contact with the air. After contact with the air, an oxide layer will be generated on the surface of the die-casting. At this time, if a fan is used directly for air cooling, the die-casting surface will be attached with an oxide layer, resulting in uneven wind reception, causing uneven cooling of various parts of the die-casting, which will affect the performance of the die-casting. At the same time, since the die-casting is in contact with the conveyor belt, it is difficult for the air cooling airflow to enter the contact position between the die-casting and the conveyor belt, affecting the cooling efficiency and causing uneven cooling effects on various parts of the die-casting.

[0019] Compared with the existing technology, the advantages of the present invention are:

[0020] 1. The conveyor belt system in this application utilizes perforated stainless steel chain plates. The hole density increases from the edge to the center of the die-casting, compensating for differential heat dissipation at the edges. Combined with the upward-angled second and third fans and the introduction of low-temperature nitrogen into the tunnel, this creates forced convection through the die-casting, allowing cool air to penetrate from above, below, and through the gaps, significantly improving cooling efficiency. The semi-enclosed tunnel structure maintains a slightly positive internal pressure, preventing oxygen ingress and reducing surface oxidation. This dynamic transmission process avoids static accumulation, ensuring uniform and stable heat dissipation and addressing the localized overheating and oxidation issues associated with traditional cooling.

[0021] 2. This application utilizes multiple sets of electric telescopic rods (first through fourth) and spherical connectors to independently adjust the height and angle of the gaskets, creating a curved support surface that adapts to the contoured surface of the die-cast part, limiting movement and expanding the support area. The conveyor belt and telescopic rods work together to achieve non-stop conveying. When the first set of rods supports the die-cast part to the middle position, the second set resets to take over the next die-cast part, improving automation efficiency. The telescopic rods alternately lift the die-cast part and rotate it 15°, shifting the support point while avoiding fixed contact. This ensures that all parts are fully exposed to the cold air, eliminating localized cooling blind spots, and ensuring uniform temperature distribution.

[0022] 3. This application utilizes dynamic wind speed adjustment during the three stages of pre-cooling, forced cooling, and natural cooling, combined with die-casting rotational speed and direction control (alternating forward and reverse), to avoid thermal stress concentration caused by sudden changes in wind speed. Multiple fans are arranged symmetrically and diagonally (blowing from below, staggered from above, and combining blowing and suction on both sides), providing full surface coverage without blind spots. The combined effect of rotating airflow direction and die-casting linear speed extends contact time and enhances convection. For complex die-castings, reverse airflow removes heat buildup in dead corners, reduces the risk of residual stress and deformation, and improves cooling quality consistency.

DETAILED DESCRIPTION

[0035] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0036] Reference Figures 1 to 11A cooling device for die-casting equipment for loom accessories includes an outer mounting housing 1. The outer mounting housing 1 consists of a base located below and a cooling housing located above, with a tunnel-like design formed between the two. The outer mounting housing 1 has a convex shape when viewed from the side. Two parallel conveyor belts 5 are mounted above the base. These conveyor belts 5 are conventional stainless steel perforated chain conveyor belts, with a gap between them. The die-casting parts are placed on their respective ends on the corresponding conveyor belts 5, with the center of the conveyor belts located above the gap between the two conveyor belts 5. Multiple air outlets 7 are provided on the side walls of the base.

[0037] Second fans 9 are fixedly installed on both sides of the lower part of the base. The two second fans 9 are arranged in mirror symmetry and both face the side of the conveyor belt device 5. The wind blown out by the second fans 9 passes through the conveyor belt device 5 to cool the die-casting. Multiple third fans 10 are fixedly installed between the two second fans 9. The third fans 10 also face the side of the conveyor belt device 5 and are used to cool the die-casting.

[0038] A fixed plate 17 is provided at the middle position inside the base, and the fixed plate 17 is arranged perpendicular to the conveyor belt device 5. A first limiting rod 15 and a first screw rod 23 are provided on one side surface of the fixed plate 17 in parallel, and a second limiting rod 16 and a second screw rod 24 are provided on the other side surface in parallel. The first limiting rod 15 and the second limiting rod 16 are fixedly connected to the fixed plate 17 and the inner wall of the base, and the first screw rod 23 and the second screw rod 24 are rotatably connected to the fixed plate 17 and the inner wall of the base. The first screw rod 23 is driven by a first motor 6 fixedly mounted on the base, and the second screw rod 24 is driven by a second motor 12 fixedly mounted on the base.

[0039] A movable housing 18 is installed between the first limiting rod 15 and the first screw rod 23, and another movable housing 18 is installed between the second limiting rod 16 and the second screw rod 24. The structures of the two movable housings 18 are exactly the same. An annular housing 19 is fixedly installed at the middle position of the movable housing 18. A first outer gear ring 25 is rotatably installed on the upper part of the annular housing 19, and a second outer gear ring 27 is rotatably installed on the lower part of the interior. A second gear 30 is rotatably installed on one side of the interior of the movable housing 18, and the second gear 30 is driven by a fourth motor 31 fixedly installed on the movable housing 18, and the second gear 30 is meshed with the outer surface of the first outer gear ring 25. A first gear 28 is rotatably installed on the other side of the interior of the movable housing 18, and the first gear 28 is driven by a third motor 29 fixedly installed on the movable housing 18, and the first gear 28 is meshed with the outer surface of the second outer gear ring 27. By setting the third motor 29 and the fourth motor 31, the corresponding second outer gear ring 27 and the first outer gear ring 25 can be individually controlled to rotate.

[0040] A plurality of horizontally distributed first electric telescopic rods 20 are fixedly installed on the inner side wall of the first outer gear ring 25 at equal intervals, and the telescopic end of the first electric telescopic rod 20 is fixedly connected to the second electric telescopic rod 21 arranged perpendicularly thereto, and the telescopic end of the second electric telescopic rod 21 is connected to a gasket 32 through a spherical connector. A plurality of horizontally distributed fourth electric telescopic rods 26 are fixedly installed on the inner side wall of the second outer gear ring 27 at equal intervals, and the fourth electric telescopic rods 26 are staggered with the first electric telescopic rod 20. The telescopic end of the fourth electric telescopic rod 26 is fixedly connected to the third electric telescopic rod 22 arranged perpendicularly thereto, and the telescopic end of the third electric telescopic rod 22 is connected to a gasket 32 through a spherical connector. The gasket 32 on the second electric telescopic rod 21 and the gasket 32 on the third electric telescopic rod 22 alternately support the middle position of the die-casting and lift it up, and the rotation of the first outer gear ring 25 and the second outer gear ring 27 can drive the die-casting to rotate.

[0041] A telescopic device is fixedly installed inside the gasket 32, and the working end of the telescopic device is connected to the telescopic plate 34. The side wall of the gasket 32 is provided with a slot for the telescopic plate 34 to pass through. The gasket 32 and the telescopic plate 34 are both made of graphite, which can withstand the high temperature after the pressure casting is demolded and will not affect the supporting effect due to thermal deformation.

[0042] Two front and rear support mechanisms are provided above the conveyor belt device 5, and the two support mechanisms are respectively located on both sides of the fixed plate 17. The support mechanism includes two support nets 14 that are symmetrically distributed on the left and right. The support nets 14 span the corresponding conveyor belt device 5, and the end of the support net 14 close to the gap is slidably connected to the side wall of one end of the conveyor belt device 5 through a slider, and the end of the support net 14 away from the gap is slidably connected to the side wall of the other end of the conveyor belt device 5 through a lifting assembly. The lifting assembly includes a U-shaped sliding plate 11 that is slidably connected to the side wall of the conveyor belt device 5, and the U-shaped sliding plate 11 is fixedly installed with a sliding groove 37 on one end close to the support net 14, and a sliding block 38 is slidably connected inside the sliding groove 37. The sliding block 38 has its own power and can move up and down inside the sliding groove 37, thereby driving one end of the support net 14 to move up and down. Specifically, the support net 14 is made of graphene electric heating film material and has a super heat dissipation effect. It can improve the heat dissipation effect while ensuring support. A magnet is fixedly installed on the inner side of the lower end of the U-shaped sliding plate 11, and an electromagnet 33 corresponding to the position of the magnet is fixedly installed on the side of the movable shell 18. The electromagnet 33 can generate magnetic force after being energized, thereby adsorbing the U-shaped sliding plate 11, so that the movable shell 18 can drive the U-shaped sliding plates 11 on both sides to move synchronously while moving.

[0043] Ventilation windows 2 are installed on the left and right side walls of the cooling shell, and an inner layer installation shell 4 is fixedly installed inside the cooling shell. Multiple first fans 8 are installed on the left and right side walls of the inner layer installation shell 4. The first fan 8 on one side is responsible for suction, and the first fan 8 on the other side is responsible for blowing. A cavity is formed between the inner layer installation shell 4 and the inner top wall of the cooling shell. An air intake pipe 3 connected to the interior of the cooling shell is fixedly installed on the top of the cooling shell. The air intake pipe 3 is used to continuously pass high-purity low-temperature nitrogen into the cavity. Multiple fourth fans 13 are staggered and distributed on the top wall of the inner layer installation shell 4. Multiple micro motors 35 are evenly distributed inside the second fan 9, the third fan 10 and the fourth fan 13. The output end of each micro motor 35 is keyed to a blade 36. The deflection angle of each blade 36 can be adjusted by the micro motor 35, thereby realizing the adjustment of the airflow direction.

[0044] After the die-casting is demolded, the present invention places the die-casting at the entrance of the device, and places both sides on the conveyor belt device 5, and limits the middle with a second electric telescopic rod 21. The conveyor belt device 5 is then started, and the die-casting will move along with the conveyor belt device 5, and then the die-casting is cooled. The die-casting is cooled while continuously moving on the conveyor belt device 5, which can avoid local overheating caused by static accumulation and ensure that the heat dissipation process is uniform and stable. In addition, the conveyor belt device 5 is a stainless steel perforated chain plate conveyor belt. The punching allows cold air to penetrate from below, and cooperates with the upwardly inclined second fan 9 and the third fan 10 to form a through-flow cooling. The cold air forms forced convection through the gap between the perforated chain plate and the die-casting, thereby improving the cooling efficiency. The distribution of holes on the conveyor belt device 5 follows the principle of denser distribution near the die-casting and sparser distribution near the sides to compensate for the fast heat dissipation at the edge. The tunnel cooling method is adopted above the conveyor belt device 5, which can more effectively control the wind distribution during the cooling process. For this semi-enclosed space, high-purity low-temperature nitrogen is continuously introduced through the air inlet pipe 3 as a cooling medium, so that the internal air pressure is slightly higher than the external pressure, preventing oxygen from entering, which can effectively reduce the degree of oxidation on the surface of the die-casting.

[0045] The middle of the die-casting is in contact with a ring formed by multiple independent gaskets 32. The gasket 32 can be independently lifted or rotated through the first electric telescopic rod 20, the second electric telescopic rod 21, the third electric telescopic rod 22, the fourth electric telescopic rod 26 and the spherical connector, which can more comprehensively adapt to the special-shaped surface of the die-casting, and finally form an arc-shaped lifting surface to further limit the movement of the die-casting.

[0046] When the die-casting moves on the conveyor belt device 5, the first motor 6 is started, and the second electric telescopic rod 21 and the third electric telescopic rod 22 are driven to move synchronously through the first screw rod 23. When the die-casting reaches the middle position of the conveyor belt device 5, the middle position of the die-casting is supported by the first second electric telescopic rod 21 and the third electric telescopic rod 22, and the second electric telescopic rod 21 and the third electric telescopic rod 22 return to their original positions to support the next die-casting. In this way, through the cooperation of the conveyor belt device 5 and the second electric telescopic rod 21 and the third electric telescopic rod 22, non-stop automatic conveying and cooling can be achieved, thereby accelerating the heat dissipation rhythm.

[0047] When supporting the die-casting, the second and third electric telescopic rods 21 and 22 are first activated to lift the die-casting to a certain height. This reduces the contact time between the die-casting and the conveyor belt device 5 and disrupts the static thermal boundary layer. The fourth motor 31 is then activated, driving the second electric telescopic rod 21 via the second gear 30 and the first outer gear ring 25, causing the second electric telescopic rod 21 to rotate the die-casting 15°. The third electric telescopic rod 22 remains stationary. The die-casting is then lowered via the second electric telescopic rod 21, and the third electric telescopic rod 22 again lifts the die-casting. The third motor 29 is then activated, driving the third electric telescopic rod 22 via the first gear 28 and the second outer gear ring 27, rotating the die-casting 15° before lowering it. This continuous rotation of the die-casting ensures that all parts of the die-casting are fully exposed to the cooling air, thus preventing local overheating or insufficient cooling. In addition, by alternately raising and rotating the second electric telescopic rod 21 and the third electric telescopic rod 22, the support points are constantly changing and will not overlap within a week, thereby avoiding the problems of local overheating or uneven heating that may be caused by fixed support positions, ensuring that the temperature distribution of the die-casting is more uniform during the cooling process, thereby improving the cooling effect.

[0048] After the die-casting enters the cooling tunnel, the initially lifted die-casting will be pressed against the support nets 14 on both sides. At this time, the electromagnet 33 is activated to adsorb the U-shaped sliding plate 11, and the support nets 14 will move along with the die-casting. During the lifting process of the second electric telescopic rod 21 or the third electric telescopic rod 22, the support nets 14 on both sides will also be lifted along with it through the sliding of the sliding block 38. When the length and width of the die-casting are quite different, the supporting effect of the support net 14 can ensure that the various parts of the die-casting are evenly stressed. When the die-casting starts to rotate, the support net 14 moves downward for a distance as a buffer to prevent the die-casting from directly hitting the conveyor belt device 5 when it falls. At the same time, it can also prevent the die-casting from getting entangled with the support net 14 during rotation. After the rotation is completed, the support net 14 moves upward again to support the die-casting. During the lowering process of the die-casting, the middle second or third electric telescopic rod 21 or 22 descends first, followed by the two side support nets 14, which are then lowered at a slower rate. The cushioning properties of the support nets 14 reduce the shaking or tilting of the die-casting, thereby reducing the possibility of the die-casting colliding with the moving support nets 14. Furthermore, die-castings with a large length-width difference are prone to falling between the two conveyor belts 5 during rotation. Therefore, each time the die-casting is lifted, the telescopic plate 34 within the spacer 32 between the two conveyor belts 5 extends, slightly extending the corresponding first or fourth electric telescopic rod 20 or 26. This not only increases the overall support area, but also compresses the telescopic plate 34 after the die-casting is lowered. Due to the elasticity of the telescopic plate 34, the first or fourth electric telescopic rod 20 or 26 is slightly shortened to apply a certain preload force, thereby clamping the die-casting and ensuring the stability of its rotation and movement. Both the gasket 32 and the expansion plate 34 are made of graphite, which can withstand the high temperatures after the die casting is demolded without thermal deformation affecting the support effect. Graphite's layered structure also gives it excellent self-lubricity, reducing friction and wear between the die casting and the supporting or clamping part. The support mesh 14 is made of graphene electric heating film material, which has excellent heat dissipation, ensuring support while also improving heat dissipation.

[0049] When the die-casting is placed on the conveyor belt device 5, the second fan 9 is immediately activated for pre-cooling. At this time, the airflow is relatively low, and its main purpose is to reduce its initial temperature in preparation for subsequent cooling. After the pre-cooling stage, the die-casting enters the cooling tunnel. At this time, the wind speed is gradually increased by the third fan 10 to avoid a sudden drop in the surface temperature of the die-casting due to sudden changes in wind speed and reduce thermal stress. At the end of the final stage, the wind speed of the second fan 9 can be reduced or the die-casting can be allowed to cool naturally for a period of time to reduce the thermal stress caused by forced cooling and achieve a uniform drop in the internal temperature of the die-casting. In addition, the entire air cooling process is coordinated with the rotation of the die-casting. Initially, the die-casting rotates at a low speed in the pre-cooling state to avoid direct contact with the high-flow medium, which may cause excessive local temperature differences. At this time, the speed must ensure uniform heat dissipation across all parts of the part rather than rapid cooling. Subsequently, the speed can be slightly increased in sync with the increase in wind speed. Centrifugal force enhances the fluidity of the medium and accelerates heat dissipation. During this stage, the rotation direction can be intermittently changed, alternating between forward and reverse directions, to avoid unilateral stress concentration. Finally, the speed is gradually reduced as the wind speed increases, and the rotation is finally stopped to allow the die-casting to cool naturally, reducing the risk of deformation caused by residual stress.

[0050] A plurality of second fans 9 and third fans 10 are symmetrically arranged below the two sides of the die-casting, blowing air obliquely upward. Most of the airflow penetrates the conveyor belt device 5 and directly acts on the side of the die-casting, and a small part of the airflow acts on the middle gap to form auxiliary convection, thereby improving the uniformity of cooling of the die-casting. The second fans 9 at the inlet and outlet are tilted at a certain angle to blow towards the inlet and outlet, which can effectively prevent outdoor air from entering the interior. Since there is no obstruction above, a plurality of fourth fans 13 are installed above the die-casting in a staggered manner, which can not only cover all areas of the die-casting surface, eliminating the edge blind spots of traditional single fans, but also avoid the overlap of wind directions causing local wind speeds to be too high or too low. The first fans 8 on both sides of the die-casting blow air on one side and inhale air on the other side. In this way, by blowing air at multiple points in the up and down and horizontal directions, uniform cooling of the die-casting can be achieved, avoiding stress concentration and deformation problems caused by local overheating or overcooling. The first fan 8 is closer to the die-casting. After the hot air is generated from the surface of the die-casting, the path to the suction port is shorter. The hot air does not need to diffuse and flow through a longer space and can be sucked away by the first fan 8 more directly and quickly, thereby improving the suction efficiency.

[0051] When the die-casting rotates counterclockwise, the first fan 8 blows air horizontally from left to right. Its surface linear velocity is superimposed in the same direction as the airflow, increasing relative wind speed, significantly enhancing forced convection, and improving heat dissipation efficiency. The second, third, and fourth fans 9, 10, and 13 rotate in the same direction as the die-casting. This aligns the tangential component of the upward and downward blowing airflow with the die-casting's rotational direction, extending the contact time between the airflow and the die-casting and increasing the amount of heat transferred per unit time. By changing the angle of the blades 36 via the micromotor 35, the rotation direction of the second, third, and fourth fans 9, 10, and 13 can be aligned with the die-casting's rotational direction. Furthermore, by rotating the first fan 8 forward and reverse, the airflow direction is adjusted, turning the original air inlet into the outlet and vice versa. When rotating in the same direction as the die-casting, heat dissipation is enhanced. When rotating in the opposite direction, heat accumulation caused by prolonged rotation in the same direction can be eliminated. For cast iron parts with complex geometries, employing reverse airflow in certain areas can also help remove heat buildup in dead corners.
