[0017] The casting sand box turning device of the present invention will be described in more detail below with reference to the accompanying drawings and through specific implementation methods.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they should not be understood as limitations on the present invention.

[0019] See also Figure 1-2 The present embodiment provides a casting sand box turning device, which realizes the rapid turning of the casting sand box without hanging the sand box in mid-air. The turning rhythm is easy to control, which greatly improves the safety of the sand box during turning. The device mainly includes a base frame 1 and a rotating frame installed on the base frame 1.

[0020] The turret is rotatably connected to both sides of the base frame 1. Arc grooves 2 are provided at both ends of the base frame 1. Support pulleys 3 are installed on the inner side of the arc grooves 2. The turret includes an annular bracket 4 and a connecting plate 15. The two annular brackets 4 are fixedly connected by the connecting plate 15. The connecting plate 15 is located at the lower part of the annular bracket 4, so that the center of the sand box is located at the center line position of the annular bracket 4, thereby improving the overall stability. The outer edge of the annular bracket 4 contacts the support pulley 3, and the annular bracket 4 is supported by the support pulley 3. A driving mechanism is provided at the end of the annular bracket 4, and the driving mechanism includes a driving motor 14, a pulley 12 and a belt 13.
