[0016] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0017] The utility model of the application discloses a die-casting device for a low-pressure gravity casting casing.

[0018] Reference Figure 1-2 The die-casting device of the low-pressure gravity casting casing includes a mounting frame 1, a heating furnace 2 arranged on the mounting frame 1, a core 3 arranged on the mounting frame 1 for lifting and lowering, a plurality of mounting plates 4 arranged on the mounting frame 1, and a plurality of control components 5 for controlling the movement of the mounting plates 4.

[0019] The mounting frame 1 is provided with a support plate 11, the support plate 11 is located between the core 3 and the heating furnace 2, a plurality of mounting plates 4 are slidably arranged on the support plate 11, a plurality of mounting plates 4 are mutually supported to form a cavity 41, and the control assembly 5 is correspondingly arranged with the mounting plate 4. Specifically, in this embodiment, four mounting plates 4 are provided, and four groups of control assemblies 5 are provided.

[0020] The mounting frame 1 is also provided with a sliding protrusion 12, and the bottom end of the heating furnace 2 is provided with a sliding groove 21 adapted to the sliding protrusion 12, and the heating furnace 2 is slidably arranged on the mounting frame 1. Specifically, in this embodiment, the cross-sections of the sliding protrusion 12 and the sliding groove 21 are both triangular.

[0021] The mounting frame 1 is also provided with a lifting cylinder 13 for controlling the lifting of the core 3, and the piston rod of the lifting cylinder 13 is connected to the core 3. Specifically, in this embodiment, the mounting frame 1 is provided with a round hole (not numbered in the figure) for passing the piston rod.

[0022] The mounting frame 1 is provided with a plurality of ash receiving grooves 14. Specifically, in this embodiment, the ash receiving grooves 14 are located below the support plate 11, and four ash receiving grooves 14 are provided, and the four ash receiving grooves 14 are respectively located around the support plate 11. When the housing is die-cast, the material overflowing from the gap between the core 3 and the cavity 41 surrounded by the plurality of mounting plates 4 flows into the ash receiving grooves 14 along the support plate 11, thereby collecting the overflowing material and reducing the waste of the material.

[0023] The control assembly 5 includes a rotating motor 51, a rotating screw 52 and a sliding block 53. The output shaft of the rotating motor 51 is coaxially fixed with the rotating screw 52.

[0024] The die casting device of the low-pressure gravity casting housing also includes a fixing assembly 6 for fixing the heating furnace 2, the fixing assembly 6 includes a connecting pipe 61 connecting the support plate 11 and the heating furnace 2, and a first magnetic block 62 arranged on the connecting pipe 61 and a second magnetic block 63 arranged on the heating furnace 2, the first magnetic block 62 and the second magnetic block 63 attract each other. Specifically, the mounting frame 1 is provided with a mounting hole (not numbered in the figure) for passing the connecting pipe 61.

[0025] When die casting is completed and cooling and demoulding are required, force is applied to the heating furnace 2 so that the second magnetic block 63 on the heating furnace 2 is separated from the first magnetic block 62 on the connecting tube 61, thereby stopping the heating of the material and facilitating cooling and demoulding. When heating is required, the heating furnace 2 is slid along the sliding protrusion 12 on the mounting frame 1 until the second magnetic block 63 on the heating furnace 2 and the first magnetic block 62 on the connecting tube 61 attract each other, so that the heating furnace 2 and the connecting tube 61 are relatively fixed, so that the heating furnace 2 can heat the material in the cavity 41 surrounded by the plurality of mounting plates 4.

Then put the material into the cavity 41 formed by a plurality of mounting plates 4 supporting each other, and then start the lifting cylinder 13, and the piston rod of the lifting cylinder 13 drives the core 3 to descend until the material in the pressing cavity 41 is formed. In this way, it is possible to achieve casings suitable for the production of different wall thicknesses.
