[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] Refer to Figures 1 to 4, the present utility model provides a reinforcement device for a leakage-proof box used in steel casting, which includes a main baffle 1, a movable sand baffle 2, a connection structure 3, side baffles 4 and a limit knob 5. The main baffle 1 is of a U-shaped structure. The length value of the main baffle 1 is adapted to the distance between the inner sides of the box ears on the sand box, and the height value of the main baffle 1 is adapted to the distance between the two sand boxes. The top of the horizontal end of the main baffle 1 is movably connected with a movable sand baffle 2 through a connection structure 3. The connection structure 3 can be a welded hinge. Under the action of an external force, the movable sand baffle 2 can rotate. And when the movable sand baffle 2 is in a vertical state, there is a connection gap between the horizontal end of the main baffle 1 and the movable sand baffle 2, and the size of the connection gap is 2-4 mm. And the side of the movable sand baffle 2 away from the connection structure 3 is flush with the side of the horizontal end of the main baffle 1 away from the connection structure, which is convenient for the use of the device.
[0020] The top of the outer side of the horizontal end of the main baffle 1 is movably connected with a limit knob 5. One end of the limit knob 5 close to the movable sand baffle 2 is a flat surface, and the other end of the limit knob 5 close to the movable sand baffle 2 is an inclined surface. Through the setting of the limit knob 5, when the end of the limit knob 5 with the inclined surface is upward, the movable sand baffle 2 can rotate under the action of an external force until the movable sand baffle 2 contacts the inclined surface of the limit knob 5. At this time, it is convenient for the staff to fill the sand. And when the end of the limit knob 5 with the inclined surface is downward, the limit knob 5 can limit the movable sand baffle 2, so that the movable sand baffle 2 cannot rotate. This device can block sand for the leakage-proof box used in steel casting.
[0021] From the above description, it can be seen that when the device is in use, the user can control the opening and closing of the movable sand baffle 2 by controlling the position of the limit knob 5, which improves the convenience of the device during use.
[0022] Both outer sides of the two ends of the main baffle 1 are fixedly connected with cross braces 9. The outer ring of the cross braces 9 is movably sleeved with side baffles 4. And the side baffles 4 include a plurality of side baffle bodies 8 with different structures. A slot 7 adapted to the cross braces 9 is provided in the middle of the side baffle body 8. The length value of the side baffle 4 is adapted to the width of the reinforcing rib plate on the outer side of the sand box, and the height value of the side baffle 4 is adapted to the distance between the two sand boxes. The side baffle 4 is in close contact with both the main baffle 1 and the limit plate 6. Adjacent two side baffle bodies 8 are in close contact with each other. And when the device is spliced, the number of movable side baffles 4 can be increased or decreased according to requirements, so that the size of the reinforcement device can adapt to the different heights of the combined boxes of various sand boxes on site, improving the adaptability of the reinforcement device and reducing the cost. When the device is in use, by moving the side baffle bodies 8 of different sizes, the device can adapt to the different heights of the combined boxes of various sand boxes on site, improving the convenience of the reinforcement device during use.
[0023] The other end of the cross brace 9 is fixedly connected with a limit plate 6. The limit plate 6 is L-shaped. One end of the limit plate 6 is fixedly connected with the cross brace 9. The other end of the limit plate 6 on the side far from the cross brace 9 is flush with the side of the horizontal end of the main baffle 1 far from the limit knob 5. And the length value of the limit plate 6 is adapted to the distance between the outer sides of the box ears fixing two sand boxes. The limit plate 6 can limit the side baffle 4.
[0024] In summary: When implementing the steel casting leakage-proof box reinforcement device, the user makes the main baffle 1, the movable sand baffle 2, and the side baffle 4 using different thin steel plate materials according to the actual situation to meet the strength requirements for safe production. The user adjusts the length, width dimensions and quantity of the main baffle 1, the movable sand baffle 2, and the side baffle 4 according to the size between the box ears of the sand box, and after welding and splicing, they become an integral whole, as shown in the appendix Figure 2 as shown.
[0025] When using this reinforcement device, place this reinforcement device in the middle of the two sand boxes when they are closed, and fix this reinforcement device to the sand boxes by using the bolts of the box ears, as shown in the appendix Figure 1 as shown.
[0026] Open the movable sand baffle 2, fill the space between the sand boxes here with molding sand, close the movable sand baffle 2, and lock the movable sand baffle 2 with the limit knob 5.
