Casting pot with stopper used for gravity casting of aluminum alloy

Abstract

Provided is a casting pot with a stopper used for gravity casting of aluminum alloy. The casting pot is characterized in that a pot mouth 1 of a casting pot 5 is provided with a pot stopper 2; the pot stopper 2 is provided with a pot-casting rod 3; the casting pot 5 is provided with a pot block 4 and a casting pot opening 10; the pot block 4 is provided with a pot frame 9, on which a positioning hole 8 of the pot-casting rod is arranged; the positioning hole 8 of the pot-casting rod is connected with the pot-casting rod 3; the pot-casting rod 3 is provided with a pull rod 7 of the pot stopper; the upper end of the pull rod 7 of the pot stopper is provided with a pull ring 13; the upper end of a pot rod 11 on one side of the casting pot 5 is provided with a pot grip 14; and a positioning ring 12 is arranged at the pot rod at the lower portion of the pot grip 14. The casting pot with the stopper used for gravity casting of aluminum alloy has following beneficial effects: the manner that the pot mouth with the pot stopper is soaked under the liquid level of aluminum melt and then the pull rod ring 13 is pulled to open up the pot mouth for taking liquid is adopted instead of taking a conventional method that aluminum melt can only be baled out on the liquid level of aluminum melt for using a casting ladle; dirty aluminum melt is prevented from entering the casting pot; an optimal melt-taking effect is achieved by utilization of the simplest casting pot with a stopper; the pot stopper can not only take melt but also improve controllability of casting a small casting head; and product quality is improved.

Description

technical field [0001] The invention is applied in the field of gravity casting, in particular to a pouring pot with a plug for aluminum alloy gravity casting. Background technique [0002] Gravity casting of aluminum alloy products is a more economical and efficient production method, but the pouring liquid is the aluminum surface solution taken from a ladle or a spoon, which contains more oxide impurities and tiny particles produced by moisture absorption. For air holes, although a filter screen is used, the quality of the product is still inferior to that of the product cast by taking liquid under the liquid surface used in low-pressure casting. Contents of the invention [0003] In view of the above problems, the present invention provides a pouring pot with a plug for aluminum alloy gravity casting. [0004] According to this proposal, a plugged pouring pot for aluminum alloy gravity casting is characterized in that: a pot stopper 2 is arranged on the spout 1 of the ...
