[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This embodiment provides a sand casting device for producing a pot rack, including a sand box and a mounting ring 3.

[0019] Specifically, the sand box includes an upper sand box 1 and a lower sand box 2. The upper sand box 1 and the lower sand box 2 are respectively provided with open filling ports. Sand is filled into the upper sand box 1 or the lower sand box 2 through the filling ports. After filling, the mold is removed and the upper sand box 1 and the lower sand box 2 are spliced ​​together. The positioning structure is aligned and the connection is fixed by the connecting structure 6 such as buckles. Molten metal is injected into the internal gap of the upper and lower sand boxes 2. After cooling and forming, the upper and lower sand boxes 2 can be removed to obtain the pot frame blank.

[0020] The mounting ring 3 is equipped with a leveling mechanism 4. The mounting ring 3 has an annular structure with an inner diameter larger than the outer circumference of the sand box. The leveling mechanism 4 includes a bracket 31 fixedly connected to the top of the mounting ring 3. Multiple brackets 31 are arranged in a circular array. The inner ends of the multiple brackets 31 are connected inward and a connecting ring is provided. Preferably, the connecting ring is coaxial with the mounting ring 3. A rotating rod 41 is passed through the connecting ring. The rotating rod 41 can rotate around the connecting ring. One end of the rotating rod 41 is provided with a handle for operating the rotation, and the other end is provided with a scraper 42. The scraper 42 can be rotated by operating the rotating handle.

[0021] The mounting ring 3 is detachably set on the outer periphery of the sand box, and the bracket 31 is located on the side of the filling port, so that the scraper 42 is set facing the filling port. When the scraper 42 rotates, the scraper 42 rotates along the radial direction of the filling port to scrape off the excess sand at the filling port and make the sand at the filling port flat. Preferably, the axis of the rotating rod 41 is coaxial with the center of the filling port, so that the scraper 42 can cover the entire area of ​​the filling port when it rotates a full circle, and the bottom of the scraper 42 is flush with the circumferential edge of the filling port to maintain abutment contact.

[0022] A slope is provided on one side of the scraper 42, with the slope direction facing the filling port. When the rotating rod 41 rotates, the slope of the scraper 42 applies downward pressure to the sand at the filling port, thereby scraping away excess sand while further compacting the sand in the sand box.

[0023] The mounting ring 3 and the sand box are detachably connected through the connecting structure 6. The connecting structure 6 includes a plurality of first connecting ends 5 disposed on the outer peripheral wall of the sand box, and the first connecting ends 5 are disposed close to the filling port. It also includes a plurality of second connecting ends 32 disposed on the inner peripheral wall of the mounting ring 3. When the mounting ring 3 is installed into the sand box, the plurality of second connecting ends 32 are connected to the plurality of first connecting ends 5 in a one-to-one correspondence. Preferably, the mounting ring 3 and the sand box are coaxially arranged, the plurality of first connecting ends 5 are arranged in an array, and the plurality of second connecting ends 32 are arranged in a corresponding array.

[0024] The second connecting end 32 is provided with a sliding groove, which has an opening at the end facing the first connecting end 5. The first connecting end 5 is provided with an insertion hole, which also has an opening at the end facing the first connecting end 5. Thus, when the second connecting end 32 is connected to the first connecting end 5, the two openings are positioned opposite each other. The axial inner wall of the sliding groove has a through hole communicating with the outer wall of the mounting ring 3. A connecting mechanism is provided within the sliding groove, including a pull rod 63 passing through the through hole. One end of the pull rod 63 located within the sliding groove is provided with a... The locking block 61 and the pull rod 63 are provided with a handle at one end outside the mounting ring 3. The handle is used for user gripping and operation. The axis of the pull rod 63 is collinear with the axis of the slide groove. When the axis of the pull rod 63 moves, it drives the locking block 61 to move in the slide groove. When the second connecting end 32 is connected to the first connecting end 5, the locking block 61 is moved so that both ends of the locking block 61 are located in the slide groove and the insertion hole respectively. Then, the second connecting end 32 and the first connecting end 5 are fixedly connected by the force on both ends of the locking block 61, so as to realize the installation of the mounting ring 3 onto the sand box.

[0025] A spring 62 is also fitted on the pull rod 63. The two ends of the spring 62 abut against the inner wall of the locking block 61 and the slide groove, respectively. The spring 62 forms an axial elastic force on the locking block 61 and the pull rod 63, pushing the locking block 61 toward the opening of the slide groove. When the second connecting end 32 is connected to the first connecting end 5, the spring 62 can actively push the locking block 61 into the insertion hole and keep the locking block 61 in the position of both the slide groove and the insertion hole, thus maintaining a reliable connection between the mounting ring 3 and the sand box.

[0026] Furthermore, an arc-shaped notch is provided on the outer edge of the first connecting end 5, and the end of the locking block 61 located outside the slide groove is set as a hemispherical head. When the mounting ring 3 is not installed with the sand box, the hemispherical head is exposed outside the slide groove. When the mounting ring 3 is connected to the sand box, the mounting ring 3 is moved axially towards the sand box. The hemispherical head first contacts the arc-shaped notch of the first connecting end 5 and is subjected to an inward force, causing the locking block 61 to move into the slide groove, so that the opening of the first connecting end 5 and the opening of the second connecting end 32 can gradually align. After they are fully aligned, the locking block 61 is subjected to the elastic force of the spring 62 and enters the insertion hole, realizing the connection between the second connecting end 32 and the first connecting end 5.

[0027] After the installation ring 3 and the sand box are installed in place, when the user operates the handle of any lever 63 and pulls any lever 63 outward, the connection between the other second connecting end 32 and the first connecting end 5 can still maintain the stable connection between the installation ring 3 and the sand box. Therefore, the user can operate any lever 63 to pull it outward and then release it. Under the action of the spring 62, the locking block 61 and the lever 63 will reset inward, and at the same time, the hemispherical head of the locking block 61 can impact the inner wall of the insertion hole, causing the sand inside the sand box to vibrate. By operating multiple levers 63 multiple times, the gaps between the sand inside the sand box can be effectively eliminated, ensuring that the sand is compacted.

[0028] By pulling out multiple levers 63 simultaneously, the mounting ring 3 can be quickly separated and disassembled from the sand box.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
