[0002] Gravity die casting machines primarily rely on the gravity of the molten metal itself to inject it into the mold cavity. During operation, the metal raw material (such as aluminum alloy, zinc alloy, etc.) is first melted in a furnace. After reaching a suitable temperature and liquid state, the molten metal is scooped up manually or mechanically and then poured into the sprue sleeve of the die casting machine. Under the action of gravity, the molten metal flows into the mold cavity along the sprue.

[0003] Traditional gravity die casting machines are inconvenient for adjusting the position of components. When performing maintenance and inspection, they have limited operating space and are not convenient for disassembling and assembling local parts, making them inconvenient to use.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0023] Please refer to Figures 1-4 A turnover type gravity die casting machine, including workbench 1, support leg 2, bearing assembly and die casting assembly, the workbench 1 below four house setting has the support leg 2, the die casting assembly includes hinged seat 3, support 4, first motor 5, worm wheel 6, worm 7, lifter 8, lifting plate 9 and upper die plate 10, the workbench 1 is provided with hinged seat 3, the support 4 is inverted L-shaped, the support 4 below left and right sides symmetry is provided with the rotating shaft 11 through the hinged seat 3, a group of rotating shaft 11 is through the support 4 and is connected with the center of worm wheel 6, the workbench 1 is also provided with first motor 5, the first motor 5 output is provided with the worm 7 that is engaged with the worm wheel 6, the lifter 8 is through the support 4 and is connected with the lifting plate 9, the lifting plate 9 below is also provided with the upper die plate 10, the bearing assembly includes connecting piece and lower die plate 12, the workbench 1 is also provided with the connecting piece that is connected with lower die plate 12, the lower die plate 12 is adapted with the upper die plate 10.

[0024] The workbench 1 provides a stable mounting base for each functional part such as a die-casting assembly, a bearing assembly, etc., and guarantees that each component can maintain a relatively fixed positional relationship during work. The four legs 2 arranged at the lower corners of the workbench 1 support the workbench 1 to be stably placed on a work plane such as the ground. The support 4 is in the shape of an inverted L, and the two symmetrical rotating shafts 11 of the through-hinged seat 3 arranged at the lower left and right sides of the support 4 are connected with the workbench 1, so that the support 4 can rotate relative to the workbench 1 about the rotating shafts 11 to achieve a certain angle of swing. One group of rotating shafts 11 is also connected with the center of the worm gear 6. The first motor 5 arranged on the workbench 1 (a servo motor is adopted, which can accurately control the speed, direction and other parameters) is meshed with the worm 7 arranged at the output end of the first motor 5. When it is necessary to adjust the angle of the upper mold plate 10 (for example, when a larger operating space is needed to repair and check the internal parts of the die-casting assembly), the first motor 5 is started, the motor drives the worm 7 to rotate, and according to the transmission principle of the worm gear 6 and the worm 7, the rotation of the worm 7 will drive the worm gear 6 to rotate synchronously. Since the worm gear 6 is connected with the rotating shafts 11 of the support 4, the support 4 will be driven to rotate about the rotating shafts 11, and then the upper mold plate 10 installed below the lifting plate 9 will also be flipped to change its angle. In this way, the upper mold plate 10 can be flipped to the appropriate angle, thereby effectively expanding the operating space, facilitating the maintenance personnel to approach each part inside the die-casting assembly for inspection, disassembly and other operations, and solving the problem of limited operating space of the traditional gravity die-casting machine during maintenance;

[0025] The lifter 8 penetrates the support 4 and is connected with the lifting plate 9, and the lifting plate 9 is installed below the upper mold plate 10. When it is necessary to perform a mold closing operation to prepare for die-casting, the lifter 8 (such as a common hydraulic lifter 8 or an electric push rod, which can realize stable extension and contraction) is started to extend, and the extension end of the lifter 8 will push the lifting plate 9 to move downward along the vertical direction, thereby driving the upper mold plate 10 to descend and approach the lower mold plate 12 until the upper mold plate 10 is accurately closed with the lower mold plate 12 to form a sealed cavity for the subsequent injection of liquid metal. After the die-casting is completed, the lifter 8 is controlled to contract, and the lifting plate 9 drives the upper mold plate 10 to rise to realize the mold opening operation, which is convenient for taking out the formed casting;

[0026] The guide rod 18 arranged through the top wall of the support 4 plays a key role in guiding and limiting during the lifting process of the lifting plate 9. The guide rod 18 slides along the corresponding guide hole on the top wall of the support 4, which limits the lifting plate 9 to stably lift along the vertical direction only, avoiding unstable conditions such as left-right shaking and deviation, ensuring the positional accuracy of the upper mold plate 10 during the lifting process, and ensuring the accuracy of the mold closing and opening operations as well as the mold matching during the die-casting process, which is helpful to improve the quality of the casting;

[0027] In addition, the cover 13 covering the worm wheel 6 and the worm 7 is arranged on the workbench 1, which mainly serves to protect the transmission components of the worm wheel 6 and the worm 7. During the operation of the die casting machine, the cover 13 can block the dust and sundries from the outside into the meshing area of the worm wheel 6 and the worm 7, prevent these impurities from affecting the transmission accuracy of the worm wheel 6 and the worm 7, ensure the stable and smooth meshing transmission between the two, maintain the normal operation of the entire angle adjusting function, and also help to prolong the service life of the worm wheel 6 and the worm 7, reduce the equipment maintenance caused by the failure of the transmission components, and ensure the reliable operation of the die casting assembly and even the entire die casting machine.

[0028] In the embodiment, the connecting piece includes a second motor 14, a reversible screw rod 15, a sliding block 16, and a clamping plate 17. A sliding groove is arranged on the workbench 1, and the reversible screw rod 15 and two groups of symmetrically arranged sliding blocks 16 are arranged in the sliding groove. The output end of the second motor 14 penetrates through the workbench 1 and is connected with the reversible screw rod 15. The sliding block 16 is threadedly connected with the reversible screw rod 15. The sliding block 16 is further provided with the clamping plate 17 connected with the lower die plate 12. The second motor 14 is started, and the motor drives the reversible screw rod 15 to rotate. Based on the screw transmission principle, the sliding block 16 threadedly connected with the reversible screw rod 15 will move in the sliding groove in the opposite or opposite directions (if the reversible screw rod 15 rotates forward, the sliding block 16 moves in the opposite direction; if it rotates reversely, it moves in the opposite direction). The sliding block 16 is provided with a clamping plate 17 in the shape of a Chinese character, and the clamping plate 17 is connected with the lower die plate 12. With the movement of the sliding block 16, the distance between the clamping plates 17 will change accordingly. When the sliding block 16 moves in the opposite direction, the distance between the clamping plates 17 decreases, thereby clamping the lower die plate 12, achieving stable fixation of the lower die plate 12, ensuring that the lower die plate 12 can accurately cooperate with the upper die plate 10 during the die casting process, and ensuring the stability of the cavity and the dimensional accuracy of the casting. When it is necessary to perform maintenance, inspection, replacement, etc. of the lower die plate 12, the second motor 14 is started in the opposite direction, so that the sliding block 16 moves in the opposite direction, and the distance between the clamping plates 17 is expanded, so that the lower die plate 12 can be easily released and removed from the connecting piece. This detachable connection facilitates the maintenance of the lower die plate 12 and the replacement of lower die plates 12 of different specifications according to actual production conditions, improves the versatility and convenience of use of the equipment, and facilitates the inspection and maintenance of other parts related to the lower die plate 12, further improving the flexibility and maintainability of the entire die casting machine during use.
