Clamp the inner support cylinder 4 at the center of the upper end of the intangible cultural heritage bronze drum casting base 2, and limit it through the inner ring set at the center of the upper end of the intangible cultural heritage bronze drum casting base 2. Clamp the two drum body half-molds 5 outside the inner support cylinder 4. Then fill the casting sand between the inner support cylinder 4 and the two drum body half-molds 5 and tamp it. Then level the tamped casting sand with the upper end faces of the two drum body half-molds 5 as the reference. Then limit it through the outer ring set at the center of the upper end of the intangible cultural heritage bronze drum casting base 2 and clamp the two intangible cultural heritage bronze drum casting outer molds 6 outside the two drum body half-molds 5. And screw out the stud 10 from the inner cavity between the two intangible cultural heritage bronze drum casting outer molds 6. At the same time, sleeved with a strengthening and fixing sleeve outside the two intangible cultural heritage bronze drum casting outer molds 6. Then place the intangible cultural heritage bronze drum casting drum surface mold 7 directly above the two drum body half-molds 5. And fill the casting sand between the two drum body half-molds 5 and the two intangible cultural heritage bronze drum casting outer molds 6 and tamp and level it. The intangible cultural heritage bronze drum casting upper mold 9 is clamped at the upper ends of the two intangible cultural heritage bronze drum casting outer molds 6 by rotation. And place a diaphragm between the intangible cultural heritage bronze drum casting upper mold 9 and the drum body half-molds 5, the intangible cultural heritage bronze drum casting outer molds 6 and the intangible cultural heritage bronze drum casting drum surface mold 7. Fill the casting sand into the intangible cultural heritage bronze drum casting upper mold 9 and tamp it. And before filling the casting sand, four casting pipes need to be pre-buried inside the intangible cultural heritage bronze drum casting upper mold 9. The casting pipes should be placed at the upper edge of the intangible cultural heritage bronze drum casting drum surface mold 7. After the casting sand is filled, separate the intangible cultural heritage bronze drum casting upper mold 9 and the tamped casting sand inside it from the intangible cultural heritage bronze drum casting outer molds 6 by rotation through the diaphragm. Remove the strengthening and fixing sleeves outside the two intangible cultural heritage bronze drum casting outer molds 6. Separate the two intangible cultural heritage bronze drum casting outer molds 6 and the casting sand inside them from the middle and move them away. Take out the two drum body half-molds 5 and the intangible cultural heritage bronze drum casting drum surface mold 7. And engrave patterns on the outer wall of the casting sand outside the inner support cylinder 4, the inner wall of the casting sand inside the intangible cultural heritage bronze drum casting outer molds 6, and the lower outer wall of the casting sand inside the intangible cultural heritage bronze drum casting upper mold 9. Then clamp the two intangible cultural heritage bronze drum casting outer molds 6 and the casting sand inside them outside the inner support cylinder 4 and the casting sand outside it. Cover the intangible cultural heritage bronze drum casting upper mold 9 on the upper ends of the two intangible cultural heritage bronze drum casting outer molds 6. Cast through the casting pipes pre-buried inside the intangible cultural heritage bronze drum casting upper mold 9. After cooling inside, remove the two intangible cultural heritage bronze drum casting outer molds 6. Screw away the intangible cultural heritage bronze drum casting upper mold 9. Then demold the casting sand to obtain a rough bronze drum blank. Finally, obtain the finished bronze drum after polishing.

[0027] Preferably, a through hole is provided at the center inside the base 2 for casting the intangible cultural heritage bronze drum. The inner support cylinder 4 has an opening facing downward, and the opening can communicate with the outside through the through hole inside the base 2 for casting the intangible cultural heritage bronze drum.

[0028] Preferably, a plurality of stud bolts 10 all penetrate inside the outer mold 6 for casting the intangible cultural heritage bronze drum, and the central axes of the plurality of stud bolts 10 are all perpendicular to the central axis of the outer mold 6 for casting the intangible cultural heritage bronze drum. The plurality of stud bolts 10 are evenly distributed inside the outer mold 6 for casting the intangible cultural heritage bronze drum. After the casting sand is tamped, the plurality of stud bolts 10 are screwed into the inner cavities of the two outer molds 6 for casting the intangible cultural heritage bronze drum, which can make the inside of the tamped casting sand more compact and prevent the occurrence of hollow areas inside the casting sand.

[0029] As Figure 3 shown, a screw head 11 is fixedly connected to the outer side of one end of the stud bolt 10 away from the central axis of the outer mold 6 for casting the intangible cultural heritage bronze drum. A heat dissipation inner cavity 12 penetrates outward from the inside of one end of the stud bolt 10 away from the central axis of the outer mold 6 for casting the intangible cultural heritage bronze drum. The stud bolt 10 can be rotated by pulling the screw head 11, and during the pouring and cooling process, the plurality of stud bolts 10 can dissipate heat from the inner cavities of the two outer molds 6 for casting the intangible cultural heritage bronze drum through the heat dissipation inner cavities 12 inside them, improving the heat dissipation efficiency and the cooling efficiency of the casting liquid.

[0030] As Figure 4 and Figure 5 shown, the upper mold 9 for casting the intangible cultural heritage bronze drum can rotate on the upper side of the upper end of the rotating frame 8 through the limiting rotating rod 13. The limiting rotating rod 13 rotates through the rotating shafts provided at the left and right ends and the rotating grooves inside the upper end of the rotating frame 8, and the limiting rotating rod 13 can be limited by two limiting clamping grooves 14 provided inside the lower end and the limiting clamping rods 15 fixedly connected to the inside of the rotating grooves provided at the upper end of the rotating frame 8.

[0031] Preferably, when the upper mold 9 for casting the intangible cultural heritage bronze drum and the limiting rotating rod 13 rotate forward and engage with the two outer molds 6 for casting the intangible cultural heritage bronze drum, the limiting clamping rod 15 limits the upper mold 9 for casting the intangible cultural heritage bronze drum through the limiting clamping groove 14 at the front side of the lower end of the limiting rotating rod 13, making the clamping position between the upper mold 9 for casting the intangible cultural heritage bronze drum and the two outer molds 6 for casting the intangible cultural heritage bronze drum more accurate. When the upper mold 9 for casting the intangible cultural heritage bronze drum and the limiting rotating rod 13 rotate backward and separate from the two outer molds 6 for casting the intangible cultural heritage bronze drum, the limiting clamping rod 15 limits the upper mold 9 for casting the intangible cultural heritage bronze drum through the limiting clamping groove 14 at the rear side of the lower end of the limiting rotating rod 13, enabling the lower end of the casting sand inside the upper mold 9 for casting the intangible cultural heritage bronze drum to be turned over for pattern engraving, reducing the engraving difficulty and improving the engraving efficiency.

[0032] As Figure 6As shown, both the front and rear sides inside the left end of the non-heritage bronze drum casting support frame 1 are penetrated through from front to back with locking chutes 16, and a spring groove is provided at the center inside the locking chutes 16. A locking plug 17 is slidably connected inside the locking chutes 16. A pressing ring 18 is fixedly connected to the outside of the front side at the center of the locking plug 17. A pressing spring 19 is provided at the rear end of the pressing ring 18, and the pressing spring 19 is sleeved outside the locking plug 17. Both the pressing ring 18 and the pressing spring 19 are located inside the spring groove at the center of the locking chutes 16. When filling with casting sand and casting, the locking plug 17 slides inside the locking chutes 16 through the pressing ring 18 and the pressing spring 19, and inserts into the left side inside the front and rear ends of the non-heritage bronze drum casting base 2, so that the non-heritage bronze drum casting base 2 can be locked with the non-heritage bronze drum casting support frame 1 by inserting the locking plug 17, making the bronze drum casting process more stable. When demolding the bronze drum, the left side of the non-heritage bronze drum casting base 2 can be separated from the non-heritage bronze drum casting support frame 1 by pulling out the locking plug 17, allowing the right side of the non-heritage bronze drum casting base 2 to rotate inside the right side of the non-heritage bronze drum casting support frame 1, causing it to tilt, so that the cast bronze drum rough blank and the casting sand fall from the upper end of the non-heritage bronze drum casting base 2, for demolding between the casting sand and the bronze drum rough blank, making the demolding more time-saving and labor-saving.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
