[0002] Automotive aluminum castings refer to devices and components made of pure aluminum or aluminum alloys through a casting process, specifically used in automobile manufacturing. These components are generally made by pouring heated liquid aluminum or aluminum alloys into the mold cavity of a sand mold or metal mold, and then forming aluminum parts or aluminum alloy parts of various shapes and sizes after cooling. Aluminum castings are an ideal material for lightweighting automobiles due to their excellent physical and chemical properties, such as light weight, high strength, good thermal conductivity and corrosion resistance. However, automotive aluminum castings need to be cooled evenly during the cooling process, otherwise they are prone to various defects such as shrinkage, shrinkage cavities, thermal cracks and shrinkage cracks, making them unusable.

[0003] Patent number CN214557324U discloses a uniform cooling device for aluminum castings. A rectangular fixed plate is provided above the base of the patent, and the fixed plate and the base are connected by at least four support columns; a positioning plate fixedly connected to each support column is provided below the fixed plate, and a cooling pool with an upper end opening is provided on the base directly below the positioning plate. The cooling pool is filled with coolant, and two lifting boxes are provided below the positioning plate. The bottom of the lifting box is provided with multiple through holes, and the top of the lifting box is fixedly connected to a pull rod, which movably passes through the positioning plate and is connected to the connecting block located above the positioning plate. Connection, sprockets are installed at the positions corresponding to the two lifting boxes above the fixed plate, and a chain is connected between the two connecting blocks. The chain between the two connecting blocks passes around the two sprockets in turn, and one of the sprockets is connected to the motor. The present application includes two lifting boxes, and the two lifting boxes are alternately cooled and cooled with high efficiency. Although the patent solves the above problems, it still only pursues cooling efficiency, but the cooling uniformity is low, which can easily lead to defects such as shrinkage, shrinkage holes, thermal cracks and shrinkage cracks in aluminum castings, making them unusable. Therefore, a uniform cooling device for automotive aluminum castings is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a uniform cooling device for automobile 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.

[0006] Preferably, the limiting device includes a movable side plate, a triangular plate, and an oblique groove triangular block, the movable side plate is slidably connected to the side of the protective plate away from the inner wall of the cooling pool, the triangular plate is fixedly connected to the side of the movable side plate close to the inner wall of the cooling pool, the oblique groove triangular block is fixedly connected to both sides of the inner wall of the cooling pool, the limiting device also includes a connecting rod, a rotating splint, an elastic telescopic rod, a sliding card, a slide rail, a movable splint, and a card block, the connecting rod is fixedly connected to the side of the movable side plate away from the inner wall of the cooling pool, the rotating splint is hinged to the connecting rod away from One end of the movable side panel, the elastic telescopic rod is fixedly connected to the side of the movable side panel away from the inner wall of the cooling pool, the sliding card is hinged to the end of the elastic telescopic rod away from the movable side panel, the movable splint is hinged to the side of the rotating splint close to the elastic telescopic rod, the slide rail is fixedly connected to the side of the movable splint close to the movable side panel, the card block is fixedly connected to the front and rear sides of the movable side panel through a protrusion, the sliding card is slidably connected to the inner surface of the slide rail, the side of the card block close to the movable side panel is in contact with the outer surface of the protective plate, and the upper and lower sides of the protective plate A slide groove is provided, and the inner surface of the slide groove and the movable side plate are slidably connected by a protrusion. 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] The cam is fixedly connected to the locking plate at one end thereof and the locking plate is fixedly connected to the locking plate at one end thereof. When the cam is aligned with the locking hole, the elastic force of the spring lifts the cam and inserts it into the locking hole, so that the movable square tube is locked with the fixed square tube. There are multiple locking holes on the fixed square tube, and the cam is inserted into different locking holes according to the size of the aluminum casting. After the movable bottom plate moves upward and leaves the cooling pool, the sliding rod is pulled, and the sliding rod drives the movable side plate to loosen the aluminum casting, so that the movable square tube is quickly pulled out of the fixed square tube. When the staff pulls the sliding rod, the tension of the tension spring can help the staff to pull the movable side plate and the movable square tube apart more easily.

[0008] The present invention adopts the above technical solution, which can bring the following beneficial effects: 1. This uniform cooling device for automotive aluminum castings uses rotating paddles to stir the cooling water, ensuring continuous flow. This improves the contact efficiency between the cooling water and the aluminum casting, thereby enhancing cooling uniformity. As the movable baseplate moves downward, it pushes the sliding sleeve and paddles downward, ensuring the paddles always remain below the movable baseplate. This allows the cooling water to always flow near the aluminum casting, improving cooling efficiency. The friction ring then lifts the sliding sleeve and paddles, ensuring they remain near the aluminum casting, stirring the cooling water and further enhancing cooling efficiency.

[0009] 2. The uniform cooling device for automotive aluminum castings uses a protective plate to drive the movable side plate to move downward. The protective plate and the movable side plate block the four sides of the aluminum casting to prevent the aluminum casting from sinking to the bottom of the cooling pool and being difficult to pick up. The triangular plate moves toward the side away from the inner wall of the cooling pool and approaches the aluminum casting to finally clamp it and fix it to prevent it 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, thereby better fitting the surface of the aluminum casting and improving the applicability and clamping effect of the device.

[0010] 3. The uniform cooling device for automotive aluminum castings uses the elastic force of the shrapnel to lift the cam and insert it into the lock hole, locking the movable square tube with the fixed square tube, and then locking the clamping block and the movable side plate, thereby improving the fixing effect. The cam is inserted into different lock holes according to the size of the aluminum casting, so that the movable side plate can lock it when clamping aluminum castings of different sizes, improving the applicability of the device. The sliding rod drives the movable side plate to loosen the aluminum casting, so that the movable square tube can be quickly withdrawn from the fixed square tube, facilitating the rapid removal of the aluminum casting and improving the ease of use of the device.
