[0002] Low-pressure casting is a method of filling the mold cavity with liquid metal under pressure and solidifying under a certain pressure. For aluminum alloy casting production workpieces, it is often necessary to inject aluminum liquid into some narrow spaces.

[0003] In order to facilitate the transfer of aluminum liquid, the existing patent with application number 201920498150.8 discloses a pneumatic ladle for aluminum liquid transfer pouring, which includes a furnace cover, a locking hand wheel, a rotating shaft, a pneumatic ladle, a lifting lug, a reinforcing hoop, a fork hole, a spout, a drain port, a thermocouple socket, a compressed air inlet and outlet, and an aluminum liquid injection port. The above patent adopts a pneumatically driven aluminum liquid filling method, which can smoothly fill aluminum liquid into a designated small area and is easy to operate, but this method will have the following problems:

[0004] First, when pouring aluminum liquid through aeration, the aluminum liquid is easily contaminated by air and oxidized when in contact with air, which in turn leads to more impurities in the aluminum liquid, affecting product quality.

[0005] Secondly, in the prior art, after the pneumatic ladle is transferred to the specified height by a forklift, in the process of adjusting the angle, the worker needs to rely on skilled driving skills to operate the forklift to achieve a good adjustment effect. The adjustment is relatively troublesome and requires high driving skills of the workers. Utility Model Content

[0006] The utility model aims to solve the shortcomings in the prior art and proposes a pneumatic ladle which is convenient for transferring aluminum liquid.

[0010] The angle adjustment mechanism includes a rotating shaft connected through a bearing and a central inner wall of a support seat, a stepper motor fixedly mounted on the outer wall of the lower side of the top of the support seat, a worm fixedly mounted on the output shaft of the stepper motor, and a worm wheel fixedly mounted on the bottom end of the rotating shaft. In this way, workers do not need to rely on skilled driving skills to operate the forklift, and the angle adjustment is more convenient and quick, with low requirements on the workers' driving skills, and is more friendly to workers with unskilled driving skills.

[0011] Preferably, the air extraction end of the air compression pump is connected to the inert gas storage tank through an air extraction pipe, and the air filling end of the air compression pump is connected to the compressed air inlet on the air pressure ladle body through an air filling pipe.

[0012] Preferably, an annular guide groove is opened on the top upper side of the support seat, four annularly distributed guide members are welded to the bottom outer wall of the adjustment disk, and the outer walls of the four guide members are slidably connected to the inner wall of the annular guide groove.

[0018] 2.
