Problems solved by technology

[0004] In addition, the integral furnace pressurization described in Chinese invention patent 201210290058.5 has only a very small share in the market. The reason is that the integral furnace pressurization has an area of ​​about 80 - More than 200 times, the possibility of high-temperature molten aluminum contacting air and producing oxidized slag is greater, and the entire furnace body must be strictly manufactured, and slight pressure leakage will lead to inaccurate soup delivery, strict furnace body manufacturing and precise processing The pressure control system has caused the price of this furnace to remain high, which does not conform to the actual economic effect
At the same time, because the area of ​​the pressurized chamber is too large, the amount of compressed air required for each product is larger, which virtually increases the energy input of the manufacturer. Regular cleaning of the pipe will greatly reduce the operating rate of the user's equipment

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0023] Such as figure 1 The aluminum liquid quantitative dispensing system shown includes a stopper rod 20, an outer cylinder 14, a first probe 4, a second probe 5, a driving mechanism for driving the stopper rod 20 to rotate and vertically move up and down, and a In the vacuum or pressurized air pressure generating device, the lower end of the outer cylinder 14 is set as the beak opening 141; the stopper rod 20 is placed in the outer cylinder 14, and the lower end of the stopper rod 20 is inserted into the beak opening 141, and the beak opening 141 is connected with the beak opening. The opening 141 is sealed and slidably fitted, and protrudes downward from the beak opening 141. The upper end of the stopper rod 20 seals upwards and passes through the outer cylinder 14 and is connected with the driving mechanism; the air pressure gene...

Abstract

The invention discloses a molten aluminum quantified feeding system comprising a stopper rod, an outer barrel, a first probe, a second probe, a drive mechanism for driving the stopper rod to rotate and to vertically move up and down, and an air pressure generating device for vacuuming or pressurizing. The lower end of the outer barrel is provided with a sharp opening. The stopper rod is arranged inside the outer barrel. The lower end of the stopper rod is inserted in the sharp opening and is hermetically in sliding fit with the sharp opening; the lower end of the stopper rod stretches outside the sharp opening downward; and the upper end of the stopper rod hermetically extends outside the outer barrel upward and is connected with the drive mechanism. The air pressure generating device is communicated with the outer barrel. The first probe and the second probe are respectively and fixedly inserted inside the outer barrel, and the first probe is located above the second probe. The molten aluminum quantified feeding system is able to pick and place the molten aluminum neatly, with the energy consumption being low and the cost being low.

Description

technical field [0001] The invention relates to an aluminum liquid quantitative dispensing system. Background technique [0002] For the current die casting of aluminum alloy, it is mainly divided into four types: 1. High pressure casting; 2. Low pressure casting; 3. Gravity casting; 4. Semi-solid casting. The above casting methods are different, and the production models are different, but the common point is that they all use the melting and holding furnace on the machine side. When the aluminum liquid in the melting and holding furnace is ready or the alloy is blended, it is necessary to transfer the most accurate amount of aluminum liquid to the die casting. At the receiving port of the machine, it is finally transferred to the mold cavity of the die-casting machine for die-casting; in this process, the purpose of accurate quantitative is to transfer the aluminum liquid just right, if the aluminum liquid is too small, the die-casting will fail, and the aluminum liquid wi...
