[0002] There are nine major processes in the casting of automobile stamping molds, among which modeling sand embedding is an indispensable process and also one of the most important processes. Only with good sand quality and good molding process can high-precision and high-quality products be manufactured. Sand is known as the life of casting. The transmission of casting sand used in casting molding usually requires the use of a conveying device for transportation, and the existing sand conveying device mainly adopts belt transmission or mechanical spiral transmission to transport sand from one place to another by the principle of mechanical transmission. However, the equipment volume occupies a large space, and mainly uses electricity as the source of power, with high power consumption and complicated mechanical transmission parts. At the same time, during the transmission of sand, serious wear will occur, and huge manpower and material resources will be invested in equipment inspection and maintenance. The high failure rate of equipment seriously affects production efficiency and causes great economic losses. Therefore, in view of this, the existing structure is studied and improved, and a two-stroke air sand conveying device for casting is provided to achieve a more practical purpose.

[0049] See also Figure 4The top and bottom ends of the supercharger middle section 2 are sealed and connected with the supercharger upper section 1 and the supercharger lower section 3 at contact positions through sealing rings.

[0050] See also Figure 1 A split fixing plate 16 is clamped on the outer periphery of the supercharger upper section 1, and an upper section fixing base 17 and a middle section fixing base 18 are respectively integrally formed at the bottom end of the supercharger middle section 2 and the top end of the supercharger lower section 3, and the split fixing plate 16, the upper section fixing base 17 and the middle section fixing base 18 are fixedly connected by multiple fixing rods 19.

[0051] See also Figure 2 A rotating rod 20 is installed on the top of the supercharger upper section 1 , and the bottom end of the rotating rod 20 extends to the inside of the supercharger upper section 1 and is fixedly connected to a rotating cover plate 21 , which corresponds to the inspection window 6 .

[0052] See also Figure 1 A level meter 22 is provided at the lower portion of the outer periphery of the middle section 2 of the supercharger.

[0053] See also Figure 5 The bottom end of the supercharger lower section 3 is integrally formed with a lower section fixing base 23.

[0054] See also Figure 2 The sand inlet 5 is connected to the interior of the supercharger upper section 1, and the sand outlet 11 is connected to the interior of the supercharger lower section 3.

[0055] Working principle: First, the sand in the pipeline is passed into the upper section 1 of the supercharger from the sand inlet 5, and the compressed air is introduced into the middle section lifting support 9 through the middle section air inlet 7. The middle section lifting head 10 is lifted up by the power of the compressed air and then opened to allow the regenerated sand to flow into the middle section 2 of the supercharger. When the sand is full, the level meter 22 of the middle section should know it, and the air in the middle section is discharged through the middle section air outlet 8, and the middle section lifting head 10 falls down, and the sand is stored in the middle section 2 of the supercharger; then the compressed air is introduced into the lower section through the lower section air inlet 12 again. Lift the support 14, lift up the lower section lifting head 15, and at the same time, the middle section air inlet 7 enters the compressed gas again, and the sand is quickly pushed into the lower section 3 of the supercharger. When the lower section 3 of the supercharger is full of sand, the lower section lifting head 15 falls, and the compressed air in the middle section 2 of the supercharger stops entering. At the same time, the compressed air enters the lower section 3 of the supercharger through the lower section air inlet 12 and is pressurized again, and the sand is driven out from the sand outlet 11 of the lower section 3 of the supercharger. The sand will enter the transmission pipeline until it enters the sand mixer. After a short mixing and stirring by the sand mixer, it is used for lost foam embedding sand.
