Technical Field
[0001] The utility model belongs to the technical field of casting moulds, in particular to an error-proofing structure for casting moulds. Background Art
[0002] A casting mold is a material that is easy to form in order to obtain the structural shape of a part. The mold is then placed in a sand mold to form a cavity with the same size as the part structure. A flowing liquid is then poured into the cavity. After the liquid cools and solidifies, a part with the same shape and structure as the mold can be formed.
[0003] The casting mold is composed of an upper and lower sand box. However, since the upper and lower parts of the casting mold cannot be connected in the vertical direction and are offset, the casting mold is prone to misinstallation or offset during use, resulting in defects in the finished product produced by the casting mold. Therefore, an anti-error structure for the casting mold is designed. The structure uses guide rods and hollow guide parts to guide the upper sand box when it is connected to the lower sand box, and uses limit plates, limit blocks and conical heads. After the upper sand box is connected to the lower sand box, the upper and lower sand boxes are fixed and limited, which can avoid the upper and lower parts of the casting mold from being unable to connect in the vertical direction and being offset, which causes the casting mold to be prone to misinstallation or offset during use.

The surface of the triangular limit head 13 is slidably connected to the surface of the triangular limit head 14. The front side of the hollow guide 2 is fixedly connected with a lever plate 15. Through the arrangement of the lever plate 15, the contact area between the operator and the hollow guide 2 can be increased, and the operator can get leverage when sliding the hollow guide 2, which can save the operator more effort when sliding the hollow guide 2.
[0026] Embodiment 2:
[0027] Figure 1-6The utility model shows an error-proofing structure for a casting mold according to an embodiment of the present invention, which comprises: two hollow guide members 2 slidably connected to the front side of a lower sand box 1: the left and right sides of the inner cavity of the hollow guide member 2 are rotatably connected to limit plates 3, the left and right sides of the inner wall of the hollow guide member 2 are fixedly connected to spring sheets 4, the limit plates 3 are fixedly connected to the spring sheets 4, the opposite ends of the two limit plates 3 are fixedly connected to limit blocks 5, the inner cavity of the hollow guide member 2 is slidably connected to a guide rod 6, the bottom end of the guide rod 6 is fixedly connected to a conical head 7, an upper sand box 8 is arranged just above the lower sand box 1, and a ladder panel 11 is fixedly connected to the inner wall of the ladder surface limit groove 10. A spring plate 12 is connected, and a triangular limit head 13 is fixedly connected to the opposite side of the two ladder panels 11. The hollow guide member 2 is located between the two ladder panels 11. Two concave limit blocks 16 are fixedly connected to the rear side of the lower sand box 1, and two auxiliary guide rods 17 are fixedly connected to the rear side of the upper sand box 8. The bottom end of the auxiliary guide rod 17 is slidably connected to the inner cavity of the concave limit block 16. Through the coordinated use of the concave limit block 16 and the auxiliary guide rod 17, the upper sand box 8 can be auxiliary guided when the upper sand box 8 and the lower sand box 1 are vertically docked, which can further avoid the occurrence of deviation when docking in the vertical direction.
[0028] Working principle: When the utility model is used, the user fixes the hollow guide member 2 to the front side of the lower sand box 1, and fixes the guide rod 6 and the support block 9 to the front side of the upper sand box 8. Then, when the upper sand box 8 and the lower sand box 1 are connected in the vertical direction, the conical head 7 at the bottom end of the guide rod 6 enters the inner cavity of the hollow guide member 2, and then the surface of the conical head 7 is made to fit the surface of the limit plate 3. Then, under the special shape of the surface of the conical head 7, the limit plates 3 on both sides are pushed to deflect in opposite directions until the bottom end of the conical head 7 contacts the inner wall of the hollow guide member 2. At the same time, under the action of the spring sheet 4, the limit plate 3 is reset, and the limit block 5 is embedded in the surface of the conical head 7, so as to pass through the guide rod 6 and the hollow guide member 2 are used to fix the lower sand box 1 and the upper sand box 8. When the casting is completed and the lower sand box 1 and the upper sand box 8 need to be removed, the lever plate 15 is pulled to drive the hollow guide member 2 to slide downward, and then the triangular limit head 13 and the triangular limit head 2 14 are used to push the ladder panels 11 on both sides to slide back to each other. After the hollow guide member 2 is separated from the surface of the conical head 7, the ladder panel 11 is reset under the support of the ladder surface limit groove 10 and the resilience of the spring plate 12, and then the hollow guide member 2 is limited again, so as to avoid the upper and lower parts of the casting mold from being unable to dock in the vertical direction and being offset, which makes the casting mold prone to misassembly or offset during use.
[0029] To sum up: the casting mold uses an anti-misalignment structure, which pushes the limit plates 3 on both sides to deflect in opposite directions through the conical head 7. At the same time, under the action of the spring sheet 4, the limit plates 3 are reset, and the limit blocks 5 are embedded in the surface of the conical head 7, and then the lower sand box 1 and the upper sand box 8 are fixed through the guide rod 6 and the hollow guide part 2, so as to avoid the upper and lower parts of the casting mold from being misaligned due to the inability to connect in the vertical direction, which makes the casting mold easy to be misassembled or misaligned during use.
