Description

Technical Field

[0001] This utility model relates to the field of casting application technology, and in particular to a flange positioning structure for casting molds. Background Technology

[0002] Casting molds are molds used to manufacture metal castings during the casting process. They can pour molten metal into the mold according to the designed shape and size, and after cooling and solidification, form parts or products of a specific shape. Casting molds are very important in industrial production, enabling the mass production of metal parts with complex shapes.

[0003] In the current casting process, it is necessary to position and fix the mold. The traditional fixing method usually uses bolts for fastening. However, when facing different types of casting processing, the corresponding casting mold must be replaced. This involves disassembling the original mold and re-fixing it. This operation method significantly reduces work efficiency. Therefore, this utility model proposes a casting mold flange positioning structure. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a flange positioning structure for casting molds. By configuring a clamping mechanism with rotation adjustment function on the positioning flange, this utility model realizes fast and effective clamping of different casting molds, ensuring the stability of the casting molds during processing. In addition, a locking component is provided on one side, which can lock the position of the adjusted clamping mechanism to prevent loosening caused by vibration during operation, thereby ensuring processing quality.

[0005] To solve the above-mentioned technical problems, the present invention provides a technical solution: a flange positioning structure for a casting mold, including a flange positioning plate, a convex ring fixedly connected to the top of the flange positioning plate near the center, a clamping mechanism detachably installed inside the convex ring, a locking component threaded to the side wall of the clamping mechanism, and a protective pad bolted to the top of the convex ring.

[0006] The present invention is further configured such that: a plurality of bolt holes are evenly provided in the circumferential direction near the outer wall of the flange positioning plate, and a positioning ladder is fixedly connected to the top center of the flange positioning plate.

[0007] The above technical solution facilitates the positioning and fixing of the entire flange positioning plate using bolt holes, and the positioning ladder seat can be used to position and fix the bottom of different molds, improving stability during processing.

[0008] The present invention is further configured such that: the clamping mechanism includes a rotating ring rotatably connected to the outer wall of the convex ring near the bottom position; a toothed ring is fixedly connected to the top of the rotating ring; multiple bevel teeth are meshed with the inner wall of the toothed ring; clamping blocks are fixedly connected to the other side of each of the multiple bevel teeth; and adaptation grooves are provided on the opposite surfaces of each of the multiple clamping blocks.

[0009] Through the above technical solution, the rotating ring drives the toothed ring to rotate on the outer wall of the convex ring, thereby causing the meshing bevel teeth to rotate inside the convex ring, which in turn causes the clamping blocks to rotate. Multiple clamping blocks can clamp and fix the casting mold placed at the center.

[0010] The present invention is further configured such that: the plurality of bevel teeth are respectively rotatably connected to the interior of a plurality of movable grooves opened near the top position on the outer wall of the convex ring.

[0011] The above technical solution facilitates stable rotation of the bevel gear within the movable slot when driving it, thus improving stability during clamping and fixing.

[0012] The present invention is further configured such that: the locking assembly includes a handle, a slide rod is fixedly connected to the bottom of the handle near the clamping mechanism, an inclined block is slidably connected to the outer wall of the slide rod, a spring is wrapped around the outer wall of the slide rod, and a protrusion is fixedly connected to the side wall of the inclined block near the top.

[0013] The above technical solution allows for quick driving of the rotating ring using a handle. The elasticity of the spring causes the bottom inclined block to engage with the bottom locking block, thus fixing the rotating ring after rotation. When it needs to be rotated back later, simply lift the inclined block with the protrusion to move it away from the bottom locking block to complete the rotation operation of the rotating ring.

[0014] The present invention is further configured such that: the two ends of the spring are respectively pressed against the top of the inclined block and the bottom of the handle, and the bottom of the inclined block is engaged with multiple locking blocks provided on the top of the flange positioning plate.

[0015] The above technical solution allows the bottom inclined block to engage with the corresponding locking block when the handle is rotated, thereby locking and fixing the position of the rotating ring.

[0016] The present invention is further configured such that: the protective pad is made of rubber material, and the inner wall is evenly provided with multiple slots.

[0017] The above technical solution allows the protective pad to be fitted onto the outside of the casting, preventing some debris from entering the flange positioning plate during processing and facilitating internal cleaning.

[0018] The beneficial effects of this utility model are as follows:

[0019] 1. The casting mold flange positioning structure proposed in this utility model, by configuring a clamping mechanism with rotation adjustment function on the positioning flange, enables rapid and effective clamping of different casting molds, ensuring the stability of the casting mold during the processing.

[0026] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0027] like Figures 1-4As shown, a flange positioning structure for a casting mold includes a flange positioning plate 1. Multiple bolt holes 11 are evenly distributed around the flange positioning plate 1 near its outer wall. A positioning ladder 13 is fixedly connected to the center of the top of the flange positioning plate 1, facilitating the positioning and fixing of the entire flange positioning plate 1 using the bolt holes 11. The positioning ladder 13 can also be used to position and fix the bottom of different molds, improving stability during processing. A convex ring 2 is fixedly connected to the top of the flange positioning plate 1 near its center. A clamping mechanism 3 is detachably installed inside the convex ring 2. The clamping mechanism 3 includes a rotating ring 31 rotatably connected to the outer wall of the convex ring 2 near its bottom. A toothed ring is fixedly connected to the top of the rotating ring 31. 32. The inner wall of the toothed ring 32 is connected to multiple bevel teeth 33. Each bevel tooth 33 is fixedly connected to a clamping block 34 on the other side. The multiple bevel teeth 33 are rotatably connected to multiple movable grooves 21 opened near the top of the outer wall of the convex ring 2. This allows the bevel teeth 33 to rotate stably inside the movable grooves 21 when driven, improving the stability during clamping. Each clamping block 34 has an adaptation groove on its opposite side. The rotating ring 31 drives the toothed ring 32 to rotate on the outer wall of the convex ring 2, thereby causing the bevel teeth 33 to rotate inside the convex ring 2, which in turn causes the clamping blocks 34 to rotate. The multiple clamping blocks 34 can clamp and fix the casting mold placed at the center.

[0028] like Figure 4 As shown, a locking assembly 4 is threadedly connected to the side wall of the clamping mechanism 3. The locking assembly 4 includes a handle 41. A slide rod 42 is fixedly connected to the bottom of the handle 41 near the clamping mechanism 3. A wedge block 43 is slidably connected to the outer wall of the slide rod 42. A spring 44 is wrapped around the outer wall of the slide rod 42. The two ends of the spring 44 are respectively pressed against the top of the wedge block 43 and the bottom of the handle 41. The bottom of the wedge block 43 is engaged with multiple locking blocks 12 provided on the top of the flange positioning plate 1, so that when the handle 41 is rotated, the bottom wedge block 43 can engage with the corresponding locking block 12, thereby locking and fixing the position of the rotating ring 31. A protrusion 45 is fixedly connected to the side wall of the wedge block 43 near the top. The handle 41 can be used to quickly drive the rotating ring 31, and the elasticity of the spring 44 makes the bottom inclined block 43 engage with the bottom locking block 12, thereby fixing the rotating ring 31 after rotation. When it needs to be rotated back later, simply lift the inclined block 43 with the protrusion 45 to move it away from the bottom locking block 12, and the rotation operation of the rotating ring 31 can be completed. The top of the protruding ring 2 is bolted with a protective pad 5. The protective pad 5 is made of rubber and has multiple slots evenly opened on the inner wall. The protective pad 5 can be fitted onto the outside of the casting, so that some debris will not enter the inside of the flange positioning plate 1 during processing, making it easier to keep the inside clean.

[0029] In use, the casting mold is first inserted into the flange positioning plate 1 through the protective pad 5 and positioned and fixed by the positioning ladder seat 13 at the bottom. Then, the rotating ring 31 is rotated by the handle 41, and the moving tooth ring 32 rotates on the outer wall of the convex ring 2. This causes the meshing bevel teeth 33 to rotate inside the convex ring 2, thereby causing the clamping block 34 to rotate. Multiple clamping blocks 34 can clamp and fix the casting mold placed at the center. At the same time, the inclined block 43 engages with the corresponding locking block 12 at the bottom while rotating, thereby fixing the clamped rotating ring 31. When disassembly is required later, the rotating ring 31 can be rotated back to its original position by lifting the inclined block 43 through the protrusion 45.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
