[0016] The utility model is further described below in conjunction with the accompanying drawings.

[0017] like Figure 1 and Figure 2 The utility model is an automatic continuous forming device for electrical flanges, comprising a hydraulic press 1, an upper mold 2, a lower mold 3, a feed pipe 41, a discharge pipe 42, a high-temperature flow meter 43, a heat preservation and pressure bag 44 and a smelting furnace 45. The lower mold 3 is fixed on the workbench of the hydraulic press 1, the upper mold 2 is fixedly connected to the pressure shaft of the hydraulic press 1, and a mold cavity 31 for pouring molten aluminum is provided on the lower mold 3.

[0018] One end of the feed pipe 41 is connected to the smelting furnace 45, and the other end is connected to the heat preservation and pressure bag 44. One end of the discharge pipe 42 is connected to the heat preservation and pressure bag 44, and the other end faces the mold cavity 31. The feed pipe 41 and the discharge pipe 42 are both connected to the control valve and the high-pressure meter. The molten aluminum liquid is discharged into the heat preservation and pressure bag. The heat preservation and pressure bag 44 is connected to the air pipe 45, and the air port connected to the air pipe on the heat preservation and pressure bag 44 is higher than the pipe port connected to the feed pipe 41. Air is introduced into the heat preservation and pressure bag 44, and the aluminum liquid in the heat preservation and pressure bag 44 is quantitatively pressed into the mold cavity 31 after passing through the high-temperature flowmeter 43 through the pressure difference.

[0019] After the aluminum is hydraulically pressed into the mold cavity 31, it is formed in the mold cavity 31 (no need to wait for complete cooling and forming), and then the discharge pipe 42 is removed, and the pressing shaft of the hydraulic press 1 drives the upper mold to press down, and the secondary pressure forming is performed under high temperature, so that the aluminum flange product has better tissue density. This device allows the product to be pressed after "casting", without the need for secondary heating, low energy consumption, no waste, and therefore energy-saving and environmentally friendly, and low cost.

[0020] After the pressing is completed, the pressing shaft of the hydraulic press 1 drives the upper mold to move upward, and the top cylinder 11 at the bottom of the hydraulic press 1 rises to push out the flange and the inner core 32 together. The flange is supported by the manipulator, and the top cylinder descends again, and the inner core 32 and the flange are completely disengaged. The manipulator removes the flange and starts the next flange filling and pressing.

[0021] In order to facilitate the removal of the discharge pipe 42, the utility model removes the discharge pipe by rotating, thereby preventing the discharge pipe from interfering with the downward pressure of the upper mold 2. The rotation method is as follows: the discharge pipe 42 is rotatably connected to the heat preservation and pressure pack 44 through a bearing. When the mold is pressed down, just rotate the discharge pipe. The outer wall of the discharge pipe 42 is wrapped with a heating wire and wrapped with heat preservation cotton, which can keep the aluminum liquid warm and avoid scalding the staff. The same is true for the heat preservation and pressure pack.

[0022] The discharge pipe 42 is arranged at an angle, and the discharge end of the discharge pipe 42 is higher than the feed end thereof, and the feed end of the discharge pipe 42 extends to the bottom side of the inner cavity of the heat preservation and pressure bag 44. The discharge pipe is arranged at an angle downward mainly so that when the pouring is stopped (the air supply is directly stopped), the remaining aluminum liquid in the discharge pipe 42 flows back to the heat preservation and pressure bag 44 under the action of gravity.

[0023] The utility model adopts low-pressure punching of metal solution and then adopts a hydraulic press for compression and reinforcement technology. The metal solution is continuously injected into the mold cavity, the production rhythm is high, the product has better tissue density, high strength, low energy consumption, no waste, so it is energy-saving, environmentally friendly and low cost.

[0024] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements without departing from the principle of the present invention, and these improvements should also be regarded as within the protection scope of the present invention.
