DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The following further details the specific embodiments of the utility model with reference to the accompanying drawings.

[0017] Provided by Figures 1 to 3 A multi-station centrifugal casting machine with high cooling efficiency includes a frame 1. Above the frame 1, there is a body 2. Inside the body 2, there is a pouring cavity 3. At the left end of the body 2, a front cover 4 is installed. On the front cover 4, there is a feeding port 5. At the right end of the body 2, a rear cover 6 is fixed. The rear cover 6 seals the pouring cavity 3;

[0018] Below the body 2, there is a box body 7. The upper part of the box body 7 is an open mouth. Inside the box body 7, there is coolant. Inside the box body 7, multiple nozzles 8 facing the body 2 are installed. The nozzles 8 are communicated with the coolant. On the front and rear sides of the box body 7, nuts 9 are fixed. The nuts 9 are threadedly connected with screw rods 10. The screw rods 10 are rotatably connected to the frame 1. At the lower end of the screw rod 10, a first bevel gear 11 is coaxially fixed. On the frame 1, a rotating shaft 12 in the front-rear direction is rotatably connected. On the rotating shaft 12, a second bevel gear 13 is coaxially fixed. The first bevel gear 11 and the second bevel gear 13 are meshed.

[0019] A first motor 14 is installed on the frame 1. The first motor 14 is fixedly connected to the right end of the rear cover 6 through a coupling.

[0020] In order to ensure a suitable rotational speed of the rotating shaft 12, a second motor 15 is installed on the frame 1, and the second motor 15 is coaxially and fixedly connected to the rotating shaft 12 through a speed reducer.

[0021] In order to facilitate the vertical alignment of the box body 7 and the main body 2, arc-shaped grooves 16 corresponding to the main body 2 are provided at both left and right ends of the box body 7.

[0022] In order to ensure the stability of the overall vertical sliding of the box body 7, a plurality of vertically arranged guide rails 17 are fixed on the frame 1. The nut 9 slides up and down along the guide rails 17. A positioning plate 18 is fixed at the upper end of the guide rails 17, and the screw rod 10 is rotatably connected to the positioning plate 18.

[0023] A pouring tray 19 is slidably connected left and right on the frame 1.

[0024] When the multi-station centrifugal casting machine needs to be poured during the use of the present utility model, the first motor 14 is started. The first motor 14 drives the rear cover 6 to rotate through a coupling. The rear cover 6 drives the main body 2 and the front cover 4 to rotate integrally. The pouring tray 19 is moved left and right on the frame 1, and the right end of the pouring tray 19 is extended into the pouring cavity 3 through the feeding port 5 to a suitable position. The pouring liquid is poured into the pouring tray 19. The pouring tray 19 pours the pouring liquid into the pouring cavity 3, and by moving the pouring tray 19 left and right, the orderly pouring of the pouring liquid into the pouring cavity 3 is realized. Under the action of the centrifugal rotation of the main body 2, the centrifugal pouring of the pouring liquid is realized;

[0025] When the multi-station centrifugal casting machine needs to be cooled, the second motor 15 is started. The second motor 15 drives the rotating shaft 12 to rotate coaxially through a speed reducer. The rotating shaft 12 drives the second bevel gear 13 to rotate. The second bevel gear 13 drives the first bevel gear 11 to rotate. The first bevel gear 11 drives the screw rod 10 to rotate. The screw rod 10 drives the nut 9 to move upward along the guide rail 17. The nut 9 drives the box body 7 to move upward. When the arc-shaped groove 16 is close to the main body 2, there is a gap between the arc-shaped groove 16 and the main body 2, which does not affect the rotational movement of the main body 2. At this time, the nozzle 8 is opened, and the nozzle 8 sprays the cooling liquid onto the surface of the main body 2. Combining the structures of the arc-shaped groove 16 and the box body 7, the outward spraying of the cooling liquid is effectively prevented, ensuring the recycling of the cooling liquid and avoiding waste of resources. As the main body 2 rotates, the nozzle 8 can cover the entire surface of the main body 2 with the cooling liquid, effectively reducing the temperature of the main body 2 and achieving the effect of rapid cooling.

[0026] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the present utility model. Any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present utility model all belong to the protection scope of the technical solution of the present utility model.
