[0030] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0031] Please refer to Figures 1-9. The present invention will be described in detail below with reference to the accompanying drawings and embodiments:

[0032] As shown in Figures 1-3, a vertical sand-shooting conversion mechanism for a horizontal and vertical dual-purpose core-making machine includes a sand-shooting cylinder 1, an upper adapter plate 2, a lower adapter plate 3, and a vertical core box 4 arranged sequentially from top to bottom. The sand-shooting cylinder 1 is filled with core sand mixture for core making. Several connecting components 5 are arranged around the upper adapter plate 2 and the lower adapter plate 3, as well as around the lower adapter plate 3 and the vertical core box 4, to fix the upper adapter plate 2, the lower adapter plate 3, and the vertical core box 4. A first sealing groove 21 and a second sealing groove 31 are respectively opened on the lower end face of the upper adapter plate 2 and the lower adapter plate 3. Sealing rings are installed in both the first sealing groove 21 and the second sealing groove 31 to enhance the airtightness of the connection between the upper adapter plate 2 and the lower adapter plate 3, as well as between the lower adapter plate 3 and the vertical core box 4. The aforementioned vertical core box 4 and sealing rings are existing technologies, and the vertical core box 4 here is a general core box in the prior art, which will not be drawn and described in detail here.

[0033] The vertical sand-shooting conversion mechanism can be installed at the sand-shooting station of the horizontal and vertical dual-purpose shell core machine. A hydraulic cylinder is fixed on the upper surface of the upper adapter plate 2 to drive the vertical sand-shooting conversion mechanism to lift and lower for sand-shooting. In this embodiment, the inner cavities of the upper adapter plate 2 and the lower adapter plate 3 are used to compensate for the stroke of the hydraulic cylinder to avoid a short stroke. The reinforcing ribs on both sides of the upper adapter plate 2 and the lower adapter plate 3 are used to improve the support. The above-mentioned hydraulic cylinder and the horizontal and vertical dual-purpose shell core machine are existing technologies and will not be drawn and described in detail here.

[0034] Furthermore, during vertical sand blasting, the upper and lower adapter plates are fixedly connected by a connecting assembly to perform vertical sand blasting. During horizontal sand blasting, the lower adapter plate and vertical core box are removed, and then a special sand blasting plate is installed at the lower end of the upper adapter plate to perform horizontal sand blasting.

[0035] As shown in Figures 4-9, the connecting component 5 includes a first clamping block 51 and a second clamping block 52 arranged symmetrically at the top and bottom. Both the first clamping block 51 and the second clamping block 52 are L-shaped. Rubber pads 53 are fixedly provided on the corresponding horizontal surfaces of the first clamping block 51 and the second clamping block 52. The rubber pads 53 can protect the connecting surfaces from being damaged by excessive pressure, and at the same time, they can enhance the friction between the first clamping block 51 and the second clamping block 52 and the connecting surfaces, preventing the first clamping block 51 and the second clamping block 52 from loosening.

[0036] As shown in Figure 4-9, the upper surface of the first clamping block 51 has a through hole 56, and countersunk holes 55 are symmetrically formed on both sides of the through hole 56. The upper surface of the second clamping block 52 has a bolt hole 523 at a position relative to the through hole 56. Guide shafts 521 are symmetrically fixed on both sides of the bolt hole 523. The guide shaft 521 is positioned corresponding to the countersunk hole 55, and the diameter of the guide shaft 521 is matched with the diameter of the small hole below the countersunk hole 55. A circular top head 524 is threaded onto the upper end face of the guide shaft 521. The diameter of the top head 524 is matched with the diameter of the large hole above the countersunk hole 55. The top head 524, in conjunction with the guide shaft 521, can ensure that the first clamping block 51 and the second clamping block 52 can move stably relative to each other, and that the two will not completely separate.

[0037] As shown in Figure 4-9, a fastening bolt 54 is slidably disposed in the through hole 56 of the first clamping block 51. After the fastening bolt 54 is inserted into the through hole 56, it can be threadedly engaged with the bolt hole 523 of the second clamping block 52, so that the first clamping block 51 and the second clamping block 52 are fixedly connected together.

[0038] In this embodiment, the first clamping block 51 and the second clamping block 52, which are separately configured, can fix the upper adapter plate 2, the lower adapter plate 3 and the vertical core box 4 of different thicknesses, without the need for clamping components of various sizes, thus improving the installation efficiency.

[0039] As shown in Figure 4-9, the first clamping block 51 has symmetrical horizontal sliding grooves 510 on both sides, and an installation groove 511 is provided outside the horizontal sliding groove 510. A sealing plate 517 is fixedly installed in the installation groove 511. The lower surface of the first clamping block 51 has symmetrical vertical sliding grooves 57 at a position away from the countersunk hole 55. The horizontal sliding grooves 510 and the vertical sliding grooves 57 are connected and can form an L-shaped through groove.

[0040] As shown in Figure 4-9, a first snap-fit ​​plate 512 is slidably disposed in the transverse slide groove 510. Several snap-fit ​​teeth are fixedly disposed on the outer side of the first snap-fit ​​plate 512. A second snap-fit ​​plate 522 is symmetrically fixedly disposed on the upper surface of the second clamping block 52. The second snap-fit ​​plate 522 can slide in the vertical slide groove 57. Several snap-fit ​​teeth are also fixedly disposed on the outer side of the second snap-fit ​​plate 522. The first snap-fit ​​plate 512 and the second snap-fit ​​plate 522 are adapted to each other, and the snap-fit ​​teeth on the outer sides of the two can mesh.

[0041] As shown in Figure 4-9, a cover plate 514 is fixedly provided on the outer surface of the first snap-fit ​​plate 512 on the other side of the snap-fit ​​tooth. A sliding shaft 515 is symmetrically fixed on the outer side of the cover plate 514. The sliding shaft 515 passes through the sealing plate 517 and slides. A spring 516 is provided between the cover plate 514 and the sealing plate 517, which is sleeved on the surface of the sliding shaft 515. The spring 516 can assist the first snap-fit ​​plate 512 to reset.

[0042] In this embodiment, after placing the first clamping block 51 and the second clamping block 52 at the connection position of the upper adapter plate 2 and the lower adapter plate 3, simply join the first clamping block 51 and the second clamping block 52 by hand, so that the second snap-fit ​​plate 522 enters the vertical slide groove 57 and engages with the first snap-fit ​​plate 512. At this time, the first snap-fit ​​plate 512 will slightly slide in the horizontal slide groove 510, and the spring 516 will help it return to its original position until the rubber pads 53 of the first clamping block 51 and the second clamping block 52 are tightly attached to the connection surface. At this time, the fastening bolt 54 can be tightened to make the first clamping block 51 and the second clamping block 52 form a final fixed state, thus completing the fixed connection of the upper adapter plate 2 and the lower adapter plate 3. The connection process of the lower adapter plate 3 and the vertical core box 4 is the same as above. This connection and installation method is simple and quick, greatly improving the installation efficiency.

[0043] As shown in Figure 4-9, a nut seat 518 is fixedly provided on the outer side of the sealing plate 517, and a rotating bolt 519 is provided on the outer side of the sealing plate 517. Part of the surface of the rotating bolt 519 is a smooth axial surface, and part of it is an axial surface with a threaded groove. The threaded groove is located on the end surface of the rotating bolt 519, which can be threadedly engaged with the nut seat 518 and can also slide through the sealing plate 517. The smooth axial surface part of the rotating bolt 519 can slide through the nut seat 518.

[0044] As shown in Figure 4-9, a rotating plate is threadedly fixed to the end face of the sealing plate 517 by the rotating bolt 519. The rotating plate is rotatably positioned between the first snap-fit ​​plate 512 and the cover plate 514.

[0045] In this embodiment, when the first snap-fit ​​plate 512 engages with the second snap-fit ​​plate 522, the first snap-fit ​​plate 512 will move within the transverse slide groove 510, and the first snap-fit ​​plate 512 will drive the rotating bolt 519 to move synchronously. At this time, the smooth axial surface of the rotating bolt 519 is engaged with the nut seat 518, so it will not affect the movement of the first snap-fit ​​plate 512.

[0046] In this embodiment, when it is necessary to disconnect the upper adapter plate 2 and the lower adapter plate 3, simply unscrew the rotating bolt 519 outwards so that the threaded groove of the rotating bolt 519 engages with the nut seat 518, causing the first snap-fit ​​plate 512 to slide outwards and disengage from the second snap-fit ​​plate 522. Then, unscrew the fastening bolt 54 to complete the fixed connection between the first clamping block 51 and the second clamping block 52 and the upper adapter plate 2 and the lower adapter plate 3. The disassembly process is simple and quick.
