[0018] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0019] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0020] Example 1, such as Figure 1-4 As shown, this utility model provides a rigid flip-top support frame for a square sand box for resin sand molding, including two supports 1, a base plate 2 fixed between the two supports 1, a connecting block 10 in each of the two supports 1, a top plate 3 rotatably connected between the two connecting blocks 10, a cross-shaped slide rail 4 at one end of the top plate 3 and the base plate 2, a telescopic rod 5 installed at each of the four ends of the inner wall of the cross-shaped slide rail 4, a connecting plate 6 fixed at the output end of the telescopic rod 5, a clamping plate 7 fixed at one end of the connecting plate 6, a flipping shaft 11 fixed inside the top plate 3, one end of the flipping shaft 11 passing through one of the connecting blocks 10 and fixed with a first ratchet 12, a first motor 14 on one side of the connecting block 10, a second ratchet 15 fixed at the output end of the first motor 14, the first ratchet 12 and the second ratchet 15 meshing and connected, and a drive structure 16 for driving the top plate 3 to lift and lower inside the support 1.
[0021] The overall effect of Embodiment 1 is as follows: by placing the two square sand boxes to be used at one end of the bottom plate 2 and the top plate 3, respectively, where the cross-shaped slide rail 4 is provided, the movement of the telescopic rod 5 inside the bottom plate 2 and the top plate 3 drives the connecting plate 6 and the clamping plate 7 to move and clamp the square sand boxes. After clamping, the operation of the first motor 14 drives the second ratchet 15 to rotate, thereby driving the first ratchet 12 to rotate, which in turn drives the top plate 3 connected to the flipping shaft 11 to rotate, so that the upper sand box is aligned with the lower sand box. At this time, the... The operation of the drive structure 16 causes the two top plates 3 to descend, thereby causing the square sand box held on its bottom side to align with the square sand box held on the top of the bottom plate 2. The four telescopic rods 5 allow the clamping plate 7 to be adjusted according to the size of the sand box, and also allow the clamping plate 7 to apply clamping force to the four ends of the sand box simultaneously, making the clamping more stable. This device, through the setting of the first ratchet 12 and the second ratchet 15, and the positioning slots of the first ratchet 12 and the second ratchet 15 every fifteen degrees, can precisely control the flipping angle.
[0022] Example 2, as Figure 1-4As shown, the drive structure 16 includes a second motor 1601 located at the top of one of the brackets 1. The output end of the second motor 1601 passes through the inner top wall of the bracket 1 and is fixed with a screw 1602. One of the connecting blocks 10 is threadedly connected to the screw 1602. A limit post 1603 is slidably connected inside the other connecting block 10. One end of the clamping plate 7 has a grid-like stress dispersion pattern 9. One end of the clamping plate 7 and the connecting plate 6 are jointly fixed with a grid-shaped reinforcing rib 8. The end of the screw 1602 away from the second motor 1601 is rotatably connected to the bracket 1. Both ends of the limit post 1603 are fixed to the bracket 1. A second fixing frame 17 is fixed at the top of the bracket 1. A first motor 14 is installed at the end of the second fixing frame 17 facing the bracket 1. One end of one of the connecting blocks 10 is fixed with a first fixing frame 13. The first motor 14 is installed at the end of the first fixing frame 13 facing the connecting block 10.
[0023] The overall effect of embodiment 2 is that the friction between the clamping plate 7 and the square sand box is increased by setting the grid-like stress dispersion pattern 9, making the clamping more stable. The strength of the connecting plate 6 and the clamping plate 7 is increased by setting the grid-shaped reinforcing rib 8, avoiding deformation and making the stability stronger. The operation of the second motor 1601 drives the screw 1602 to rotate, so that the top plate 3 is raised and lowered under the limiting cooperation of the limiting post 1603 and the two connecting blocks 10.
[0024] Working principle: When using this device, the two square sand boxes to be used are placed on the bottom plate 2 and the top plate 3 respectively, where the cross-shaped slide rails 4 are provided. The movement of the telescopic rods 5 inside the bottom plate 2 and top plate 3 drives the connecting plate 6 and clamping plate 7 to move, clamping and fixing the square sand boxes. After clamping, the operation of the first motor 14 drives the second ratchet 15 to rotate, which in turn drives the first ratchet 12 to rotate, causing the top plate 3 connected to the flipping shaft 11 to rotate, aligning the upper sand box with the lower sand box. The operation of the second motor 1601 drives the screw 160... 2. Rotation causes the top plate 3 to rise and fall under the limiting action of the limiting post 1603 and the two connecting blocks 10, thereby driving the square sand box held on its bottom side to connect with the square sand box held on the top of the bottom plate 2. The four telescopic rods 5 allow the clamping plate 7 to be adjusted according to the size of the sand box, and also allow the clamping plate 7 to apply clamping force to the four ends of the sand box at the same time, making the clamping more stable. This device, through the setting of the first ratchet 12 and the second ratchet 15, and the positioning slots of the first ratchet 12 and the second ratchet 15 every fifteen degrees, can precisely control the flipping angle.
[0025] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
