DETAILED DESCRIPTION

[0022] In order to further explain the technical scheme of the utility model, the following specific embodiments are described in detail.

[0023] As shown in Figure 1 The utility model provides a metal casting rapid cooling device, including box 1 and the box door 2 of hinged in the front end surface edge of box 1,

[0024] As shown in Figures 1 to 3 In the embodiment, the inside bottom of box 1 is provided with a collecting groove 3, and a support hole plate 4 is installed in the box 1 to completely cover the inside top of the collecting groove 3. The support plate 4 is used to provide support for the metal casting.

[0025] The right end surface of the box 1 is fixedly penetrated by a second conveying pipe 15 for conveying cooling water;

[0026] The upper side of the support hole plate 4 is provided with a sliding hole plate 5 movably connected with the inner wall of the box 1. The sliding hole plate 5 can move horizontally along the inner wall of the box 1 to realize the movement and conveying of the metal casting during the horizontal movement of the sliding hole plate 5. The holes on the sliding hole plate 5 correspond to the holes on the support hole plate 4. The upper side of the sliding hole plate 5 is provided with an electric sliding rail 6 installed on the inner wall of the box 1.

[0027] The sliding frame 7 is slidably installed on the electric sliding rail 6. The bottom end surface of the sliding frame 7 is installed with a first conveying pipe 8. The bottom of the first conveying pipe 8 is installed with two or more first atomizing nozzles 9. The upper side of the first conveying pipe 8 is provided with a corrugated pipe 10 for conveying cooling water.

[0028] The second conveying pipe 15 movably extends into the collecting groove 3. The top of the second conveying pipe 15 is installed with two or more second atomizing nozzles 16 distributed at equal intervals.

[0029] The first atomizing nozzles 9 at the bottom of the first conveying pipe 8 are distributed at equal intervals, which facilitates the uniform spraying of the cooling water on the metal casting by the first atomizing nozzles 9.

[0030] In the embodiment, the outer side of the box 1 is provided with a drain hole 18. The drain hole 18 penetrates the inner bottom of the collecting groove 3, which facilitates the connection of the drain hole 18 with a drain pipe to discharge the used cooling water in the collecting groove 3.

[0031] In the embodiment, one reflective photoelectric position sensor 11 is installed at each of the left and right ends of the inner wall of the box body 1, and one reflective sticker 12 is pasted at each of the left and right end faces of the sliding frame 7. The two reflective stickers 12 correspond to the two reflective photoelectric position sensors 11 respectively, and the reflective photoelectric position sensors 11 cooperate with the reflective stickers 12 to detect and determine the position of the sliding frame 7, so that the controller connected with the reflective photoelectric position sensors 11 and the arc-shaped electric sliding rail 6 can timely control the arc-shaped electric sliding rail 6 to stop working, thereby preventing the sliding frame 7 on the arc-shaped electric sliding rail 6 from colliding with the inner wall of the box body 1.

[0032] In the embodiment, a column of rolling balls 13 is movably embedded at each of the left and right ends of the top of the support hole plate 4, and two arc-shaped guide grooves 14 are formed at the bottom of the sliding hole plate 5. The two guide grooves 14 correspond to the two columns of rolling balls 13 respectively, and the rolling balls 13 are in rolling connection with the inner sides of the guide grooves 14, thereby reducing the friction between the support hole plate 4 and the sliding hole plate 5, and facilitating the horizontal movement of the sliding hole plate 5 to drive the metal casting.

[0033] In the embodiment, a vibration motor 17 is installed at the bottom end face of the support hole plate 4, thereby facilitating the vibration motor 17 to drive the metal casting to vibrate, so as to shake off the water droplets remaining on the metal casting, and reduce the subsequent cleaning workload of the water droplets.

[0034] Specifically, in use, the corrugated pipe 10 and the second conveying pipe 15 are connected to the external cooling water conveying equipment. The metal casting is placed on the sliding hole plate 5 by opening the box door 2, and the sliding hole plate 5 is pushed to drive the metal casting to be placed in the box body 1, and then the box door 2 is closed.

[0035] The external cooling water conveying equipment sends cooling water into the corrugated pipe 10 and the second conveying pipe 15. The cooling water in the second conveying pipe 15 is sprayed upward through the holes of the support hole plate 4 and the sliding hole plate 5 to act on the bottom end face of the metal casting, thereby cooling the bottom of the metal casting. The cooling water in the corrugated pipe 10 enters the first conveying pipe 8, and is sprayed downward through the first atomizing nozzle 9 to act on the top of the metal casting, thereby cooling the top of the metal casting. Then, the arc-shaped electric sliding rail 6 is controlled to be started, so that the sliding frame 7 drives the first conveying pipe 8 and the first atomizing nozzle 9 to move along the arc-shaped electric sliding rail 6, so as to make the cooling water sprayed by the first atomizing nozzle 9 gradually cover the side surface and the top end face of the metal casting in the moving process, thereby ensuring that the cooling water is uniformly distributed on the surface of the entire metal casting, improving the cooling effect and the cooling speed of the metal casting. The used cooling water flows downward into the collecting groove 3 for storage, thereby preventing the outflow of the cooling water from affecting the environment.

[0036] The above merely describes preferred examples of the present application and is not intended to limit the present application, and although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
