Description

Technical Field

[0001] The present invention relates to the technical field of aluminum casting production, and particularly to an even cooling device for automotive aluminum castings. Background Art

[0002] Automotive aluminum castings refer to equipment components made of pure aluminum or aluminum alloy obtained by casting, and are specifically used in automotive manufacturing. These components are generally formed by pouring molten aluminum or aluminum alloy into the mold cavity of a sand mold or metal mold, and then forming various shaped and sized aluminum parts or aluminum alloy parts after cooling. Due to their excellent physical and chemical properties, such as light weight, high strength, good thermal conductivity, and corrosion resistance, aluminum castings have become an ideal material for automotive lightweighting. However, automotive aluminum castings need to be evenly cooled during the cooling process; otherwise, various defects such as porosity, shrinkage cavity, hot crack, and shrinkage crack are likely to occur, rendering them unusable.

[0003] The patent with the patent number CN214557324U discloses an even cooling device for aluminum castings. Above the base of this patent, there is a rectangular fixing plate, which is connected to the base by at least four support columns; below the fixing plate, there is a positioning plate fixedly connected to each support column. There is a cooling pool with an open upper end at the position directly below the positioning plate on the base. The cooling pool is filled with coolant. There are also two lifting boxes below the positioning plate. The bottom of the lifting box is provided with multiple through holes. The top of the lifting box is fixedly connected to a pull rod, which movably penetrates through the positioning plate and is connected to a connecting block located above the positioning plate. At the positions corresponding to the two lifting boxes above the fixing plate, sprockets are respectively installed. A chain is connected between the two connecting blocks. The chain between the two connecting blocks sequentially bypasses the two sprockets, and one of the sprockets is connected to a motor. This application includes two lifting boxes, and the two lifting boxes alternately cool down, with high efficiency. Although this patent solves the above problems, it still has the drawback that it only pursues cooling efficiency while having a low cooling uniformity, which easily leads to defects such as porosity, shrinkage cavity, hot crack, and shrinkage crack in aluminum castings, rendering them unusable. Therefore, an even cooling device for automotive aluminum castings is proposed to solve the above-mentioned problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide an even cooling device for automotive aluminum castings in view of the deficiencies in the above-mentioned prior art.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is: a uniform cooling device for automobile aluminum castings, comprising a cooling pool, a cooling temperature controller is fixedly connected to the left side of the cooling pool, a water pipe is fixedly connected to the left side of the cooling temperature controller, a support frame is fixedly connected to the top surface of the cooling pool, a protective frame is fixedly connected to the upper surface of the support frame, a reciprocating screw is rotatably connected to the inner surface of the top end of the support frame, a transmission nut is threadedly connected to the circumferential surface of the reciprocating screw, a movable base plate is fixedly connected to the circumferential surface of the transmission nut, and protective plates are fixedly connected to the front and rear sides of the upper surface of the movable base plate.

The interior of the cooling pool is provided with a limiting device for clamping the aluminum casting to prevent the aluminum casting from floating in the water, and the interior of the cooling pool is provided with a locking device for locking the clamping component to prevent the clamping component from loosening and causing the aluminum casting to detach. The water pipe is fixedly connected to the left side of the cooling pool, and the top of the reciprocating screw is connected to the output shaft and the electric The motor is fixedly connected, and the motor is installed on the upper surface of the support frame. The reciprocating screw is rotatably connected to the bottom surface of the inner wall of the cooling pool. The reciprocating screw is connected to the sliding groove shaft through a synchronous belt. The bottom end of the return spring is fixedly connected to the bottom surface of the inner wall of the cooling pool. The bottom end of the sliding sleeve shaft and the upper surface of the resistance ring are in contact with each other. The lower surface of the movable base plate and the top of the sliding sleeve shaft are in contact with each other. The movable base plate and the circumferential surface of the sliding groove shaft are slidably connected. Place the aluminum casting of the automobile on the movable base plate and start the motor. The motor drives the reciprocating screw to rotate, and the reciprocating screw drives the transmission nut to move downward, and the transmission nut drives the movable base plate to move downward. The movable base plate then drives the protective plate and the aluminum casting downward and immerses the aluminum casting in the cooling water in the cooling pool, so that the aluminum casting cools down quickly. When the reciprocating screw rotates, it simultaneously drives the three slide shafts to rotate. The slide shaft then drives the sliding sleeve to rotate through the spline. The sliding sleeve drives the blades to rotate and stirs the cooling water to keep the cooling water flowing. When the movable base plate moves downward, it pushes the sliding sleeve and the blades to move downward, so that the blades always remain in the position below the movable base plate. When the reciprocating screw drives the movable base plate upward through the transmission nut, the elastic reset effect of the reset spring pushes the resistance ring upward, and the resistance ring then pushes up the sliding sleeve and the blades.

When the movable bottom plate moves downward, it drives the protective plate to move downward, and the protective plate drives the movable side plate to move downward. The protective plate and the movable side plate block the four sides of the aluminum casting. When the movable side plate moves downward, it drives the triangular plate to move downward. When the triangular plate moves downward, its inclined surface contacts the inclined groove of the triangular block of the inclined groove. While moving downward, the guide triangular plate of the inclined groove also moves to the side away from the inner wall of the cooling pool and approaches the aluminum casting to finally clamp the aluminum casting. When the triangular plate approaches the aluminum casting, it drives the connecting plate The connecting rod and the rotating splint approach the aluminum casting. After the rotating splint contacts the aluminum casting, it is affected by the shape and size of the aluminum casting and rotates a certain angle along the hinge with the connecting rod. At the same time, the movable side plate drives the sliding rail and the movable splint to approach the aluminum casting through the elastic telescopic rod and the sliding card. After the movable splint hits the aluminum casting, the movable side plate continues to approach the aluminum casting. At this time, the elastic telescopic rod contracts, and because of the change in the angle of the rotating splint, it pulls the movable splint and the slide rail to slide and deviate on the sliding card, so that the rotating splint and the movable splint form an angle to clamp the aluminum casting.

[0007] Preferably, the locking device includes a movable square tube, a spring piece, a convex shaft, and a fixed square tube. The fixed square tube is fixedly connected to one side of the protective plate close to the inner wall of the cooling pool.

One end of the sliding rod away from the inner wall of the cooling pool is fixedly connected to the movable side plate. One end of the tension spring away from the L-shaped connecting plate is fixedly connected to the movable side plate. The clamping block moves towards the fixed square tube and drives the movable square tube to approach the fixed square tube. When the movable square tube is inserted into the inner wall of the fixed square tube, the convex shaft is offset towards the inside of the movable square tube due to the resistance of the inner wall of the fixed square tube, thereby driving the spring piece to be pressed. When the convex shaft aligns with the lock hole, the elastic force of the spring piece lifts the convex shaft and inserts it into the lock hole, locking the movable square tube and the fixed square tube. Multiple lock holes are opened on the fixed square tube, and the convex shaft is inserted into different lock holes according to the size of the aluminum casting. After the movable bottom plate moves upward and leaves the inside of the cooling pool, the sliding rod is pulled. The sliding rod drives the movable side plate to release the aluminum casting, so that the movable square tube can be quickly withdrawn from the fixed square tube. When the staff pulls the sliding rod, the pulling force of the tension spring can assist the staff to more easily pull apart the movable side plate and the movable square tube.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects:

[0009] 1. For this automotive aluminum casting uniform cooling device, the paddle rotates and stirs the cooling water to make the cooling water flow continuously, improving the contact efficiency between the cooling water and the aluminum casting, and thus enhancing the cooling uniformity. When the movable bottom plate moves downward, it pushes the sliding sleeve shaft and the paddle downward, keeping the paddle always at the position below the movable bottom plate, and the cooling water always flows near the aluminum casting, improving the cooling efficiency. The abutting ring then pushes up the sliding sleeve shaft and the paddle, keeping the paddle near the aluminum casting to stir the cooling water, further improving the cooling efficiency.

[0010] 2. For this automotive aluminum casting uniform cooling device, the protective plate drives the movable side plate to move downward. The protective plate and the movable side plate block the four sides of the aluminum casting, preventing the aluminum casting from sinking to the bottom of the cooling pool and being difficult to fish out. The triangular plate moves away from the inner wall of the cooling pool and approaches the aluminum casting and finally clamps the aluminum casting to fix it, preventing the aluminum casting from floating in the cooling water and affecting the cooling effect. The rotating clamping plate and the movable clamping plate form an angle to clamp the aluminum casting, thus fitting more closely to the surface of the aluminum casting, improving the applicability and clamping effect of the device.

[0011] 3. For the uniform cooling device of the automotive aluminum casting, the elastic force of the elastic sheet lifts the convex shaft and inserts it into the lock hole, locking the movable square tube and the fixed square tube, and further locking the clamping block and the movable side plate, improving the fixing effect.

The triangular plate 72 is fixedly connected to the side of the movable side plate 71 close to the inner wall of the cooling pool 1. The inclined groove triangular block 73 is fixedly connected to both sides of the inner wall of the cooling pool 1. The protective plate 63 drives the movable side plate 71 to move downward. The protective plate 63 and the movable side plate 71 block the periphery of the aluminum casting to prevent the aluminum casting from sinking to the bottom of the cooling pool 1 and being difficult to fish out. The triangular plate 72 moves away from the inner wall of the cooling pool 1 and approaches the aluminum casting and finally clamps the aluminum casting to fix the aluminum casting and prevent the aluminum casting from floating in the cooling water and affecting the cooling effect. The limiting device 7 further includes a connecting support rod 74, a rotating clamping plate 75, an elastic telescopic rod 76, a sliding clamping plate 77, a slide rail 78, a movable clamping plate 79, and a clamping block 710.
