[0032] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0033] like Figures 1 to 11 As shown, a dual-purpose horizontal and vertical shell core machine includes a mounting support frame 1, a sliding frame 11 on the mounting support frame 1, the sliding frame 11 being slidable along the front-rear direction of the mounting support frame 1, a first top core plate 12 on the sliding frame 11, the first top core plate 12 being mounted on the sliding frame 11, a pin being provided below the first top core plate 12, a sandblasting device on the sliding frame 11, the sandblasting device including a sand-shooting plate 4 on the sliding frame 11, the first top core plate 12 and the sand-shooting plate 4 being independently controllable for lifting and lowering by a driver, the driver being a cylinder, a first module and a second module on the mounting support frame 1, the first module and the second module being usable independently on the mounting support frame 1.

[0034] The first module includes an upper mold 3 located below the sliding frame 11 and mounted on the mounting support frame 1. The upper mold 3 has through holes that cooperate with ejector pins on the first core plate 12. When the sand-shooting plate 4 moves above the upper mold 3 via the sliding frame 11, it descends to cooperate with the upper mold 3. First mounting plates 31 are provided on both sides of the upper mold 3. First positioning plates 13 are provided on both sides of the interior of the mounting support frame 1. The first positioning plates 13 contact the first mounting plates 31 and are fixed with bolts. A mounting base 6 is located at the lower interior of the mounting support frame 1. A lifting base 61 is located above the mounting base 6. A lower mold 2 corresponding to the upper mold 3 is mounted on the lifting base 61. A second positioning plate 21 is provided on both the left and right sides. Four fixed clamping plates 611 are symmetrically arranged on the upper two ends of the mounting base 6. The cooperation between the fixed clamping plates 611 and the second positioning plates 21 facilitates the installation or disassembly of the lower mold 2. The second positioning plate 21 is located between the two corresponding fixed clamping plates 611. The fixed clamping plates 611 are provided with positioning elements 612, which are bolts and nuts. The two corresponding fixed clamping plates 611 are fixed to the second positioning plate 21 by the positioning elements 612. In order to further limit the front and rear position of the second positioning plate 21, in this embodiment, the two ends of the second positioning plate 21 are provided with positioning grooves 211 that correspond to the fixed clamping plates 611.

[0035] In the above scheme, when the lower mold 2 and the upper mold 3 are in use, the lower mold 2 is driven to rise by the lifting base 61 and contact and close with the upper mold 3. Then, the sand-shooting plate 4 is positioned above the upper mold 3 by the sliding frame 11, and the sand-shooting plate 4 moves down to correspond with the sand inlet hole on the upper mold 3, spraying sand into the space between the lower mold 2 and the upper mold 3. At this time, the lower mold 2 and the upper mold 3 are heated by electricity to solidify the sand. Finally, the lower mold 2 is lowered by the lifting base 61 and separated from the upper mold 3. At the same time, the first core plate 12 is moved to the upper mold 3 by the sliding frame 11, and the ejector pin on the first core plate 12 is lowered and enters the through hole on the upper mold 3, thereby separating the product from the upper mold 3, so that the sand core is located on the lower mold 2. When the lower mold 2 is at its lowest position during descent, the sand core is removed from the lower mold 2.

[0036] like Figures 6 to 11 As shown, the second module includes two core-making molds 5, which are symmetrically distributed inside the mounting support frame 1. A drive unit for moving the two core-making molds 5 relative to each other is provided between the core-making molds 5 and the mounting support frame 1. A sand-shooting interface 41 is installed below the sand-shooting plate 4, and the sand-shooting interface 41 is adapted to the sand inlet hole between the two core-making molds 5.

[0037] The drive unit includes a guide push plate 51 and a fixing frame 54. The fixing frame 54 is fixed to the outside of the mounting support frame 1 by bolts. A second mounting plate 52 is fixedly connected between the guide push plate 51 and the core-making mold 5. A first driver 55 is provided on the mounting support frame 1. The first driver 55 is a cylinder. The guide push plate 51 is located inside the mounting support frame 1 and connected to the first driver 55. A fixing cover 511 is provided between the guide push plate 51 and the first driver 55. A rotating shaft 514 is rotatably mounted inside the fixing cover 511. The rotating shaft 514 passes through the guide push plate 51 and the second mounting plate 52. Plate 52 is fixedly connected, and a transmission gear 501 located inside the fixed cover 511 is sleeved on the rotating shaft 514. A drive gear 502 is provided around the transmission gear 501. A second driver 56 is installed on the side of the fixed cover 511 away from the guide push plate 51. The second driver 56 is a motor. The drive end of the second driver 56 passes through the fixed cover 511 and is connected to the drive gear 502. In order to further limit the guide push plate 51 and prevent the guide push plate 51 from rotating, a guide rod 512 is installed on the outside of the mounting support frame 1. One end of the guide rod 512 passes through the mounting support frame 1 and is connected to the guide push plate 51.

[0038] In order to demold the product between the two core-making molds 5, in this embodiment, a second top core plate 53 is provided between the core-making mold 5 and the second mounting plate 52. There is a gap between the core-making mold 5 and the second mounting plate 52 for the movement of the second top core plate 53. The second top core plate 53 is provided with ejector pins on the side facing the core-making mold 5. The core-making mold 5 is provided with through holes corresponding to the ejector pins on the second top core plate 53. The guide push plate 51 is provided with a receiving groove on the side facing the second mounting plate 52. A third driver 513 is installed in the receiving groove. The third driver 513 adopts a small cylinder or a small electric telescopic rod. The driving end of the third driver 513 passes through the second mounting plate 52 and corresponds to the second top core plate 53.

[0039] In the above scheme, when the two core-making molds 5 are in use, the two core-making molds 5 are brought close to each other by two first drivers 55. After the two first drivers 55 merge, the sand injection interface 41 moves between the two core-making molds 5 through the sliding frame 11, and the sand injection interface 41 is lowered to correspond with the sand inlet between the two core-making molds 5, spraying sand into the cavity between the two core-making molds 5. Then, the inside of the two core-making molds 5 is heated to heat and solidify the outer shell of the sand core. At this time, the drive gear 502 drives the rotating shaft 514 on the transmission gear 501 to rotate through the first driver 55. The rotating shaft 514 drives the core-making mold 5 on the second mounting plate 52 to rotate, pouring out the excess sand between the two core-making molds 5. At this time, the two core-making molds 5 are reset. During the reset, the third driver 513 passes through the second mounting plate 52 and contacts the second top core plate 53. The ejector pin on the second top core plate 53 passes through the through hole on the core-making mold 5 and pushes the product between the two core-making molds 5 down.

[0040] To facilitate the installation and disassembly of the core-making mold 5, in this embodiment, two symmetrically arranged third mounting plates 503 are provided on the side of the core-making mold 5 facing the second mounting plate 52. The two end faces of the third mounting plates 503 are provided with mounting grooves 531. The second mounting plate 52 is provided with a T-shaped groove. The second mounting plate 52 is provided with a clamping member 504. The clamping member 504 is equipped with a mounting member 541 located in the T-shaped groove. The mounting member 541 is made of bolt and nut, with the head of the bolt located in the T-shaped groove. One end of the clamping member 504 is located in the mounting groove 531, and the third mounting plate 503 is fixed to the second mounting plate 52 through the mounting member 541.

[0041] Working principle of this utility model:

[0042] When the first module is in use, the second module is not installed on the mounting support frame 1, allowing the first module to be used independently on the mounting support frame 1. When the second module is in use, the first module is removed from the mounting support frame 1, and the second module is installed on the mounting support frame 1. At the same time, the sand-shooting interface 41 is installed on the sand-shooting plate 4, so that the sand-shooting interface 41 and the second module can be used together, thus enabling the second module to be used independently, thereby increasing the application scenarios and scope of the shell core machine.

[0043] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
