Feeding spoon for cast aluminium forming

Abstract

The invention relates to a feeding spoon for cast aluminium forming, which comprises a spoon main body and a spoon cover, wherein the spoon cover is covered at the middle part of an upper opening of the spoon main body; the opening positioned in the front part of the spoon cover on the spoon main body forms a feeding port, and an opening in the rear part of the spoon cover forms a discharging port. The feeding spoon for cast aluminium forming of the invention uses the spoon cover to shield the opening part on the upper end of the spoon main body so that oxide layers can be prevented from entering the inside of the spoon main body by the method of immersing the feeding port into the lower part of aluminium liquid in the use process. In addition, the aluminium liquid can be prevented from adhering by making the rear end wall of the spoon main body into a plane shape and designing the front end of the feeding port into a sharp structure. Besides, the discharging port is designed into a semicircle and the section area of the discharging port is increased to reduce feed speed so that the aluminium liquid can be prevented from splashing, thus the feeding precision can be improved. Because of high feeding precision, the feeding quantity can be reduced, and a great amount of aluminium can be saved so that the production cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of cast aluminum forming machinery, in particular to a spoon for casting aluminum forming. Background technique [0002] The production process of steering wheel aluminum core gold is to first heat the aluminum material (ADC-6) to a temperature of 700°C in a melting furnace to melt it into a liquid state, then use a spoon to scoop up the aluminum liquid and move it to the forming machine, and then Pour the molten aluminum into the soup opening on the forming machine, measure it with a spoon at the same time, and finally die-cast the material into a product by the forming machine. figure 1 It is a side view of the soup ladle structure in the prior art. Such as figure 1 Shown, the soup ladle 1 upper end of this prior art is opening shape, and the front portion of opening is as soup inlet 2, and the rear portion of opening then is as soup outlet 3. But, there is following problem in this soup ladle 1 commonl...

AI Technical Summary

Problems solved by technology

But, there is following problem in this soup ladle 1 commonly used at present: 1, as mentioned above, the opening of this soup ladle 1 faces upwards, and aluminum is extremely easy to oxidize in the air again, at this moment the surface of aluminum liquid 4 A layer of oxide layer 5 will be formed. When the soup spoon 1 is used to scoop up the aluminum liquid 4, these oxides will inevitably enter the interior of the soup spoon 1 from the soup inlet 2, resulting in inaccurate soup accuracy.

2. The front end of the soup inlet 2 is not sharp enough, and the aluminum liquid 4 is very viscous, so the aluminum liquid 4 is easily attached there, which will also affect the accuracy of the soup feeding

3. The rear end wall of the soup ladle 1 is arc-shaped, and the viscous aluminum liquid 4 is easy to adhere to the inner wall of this place and is not easy to flow, resulting in a decline in the soup feeding ability

4. The cross-section of the soup outlet 3 is V-shaped and the width of the upper end is small. Therefore, in the process of pouring the aluminum liquid 4 into the forming machine to the soup mouth, because the cross-section at this place is relatively small, the feeding speed is fast, so Aluminum liquid 4 is very likely to splash out, and the result will also cause inaccurate accuracy of the soup

In addition, the thickness of the soup cake on the product is the premise to ensure the quality of the product. As mentioned above, due to the above-mentioned inaccurate problem of the soup ladle 1, the only way to ensure the soup in the production process is to increase the soup quantity. The thickness of the cake will cause a lot of waste of aluminum, which will lead to a substantial increase in production costs
