[0002] Precision casting is also known as lost wax casting. Compared with the traditional sand casting process, the castings obtained by precision casting are more accurate in size and smoother in surface, close to the final shape of the parts, and can be used directly without or with little processing. Precision casting is divided into investment casting, ceramic casting, metal casting, pressure casting, and lost foam casting, which generally include the following process flows: wax pressing, wax repair, tree assembly, shell making, dewaxing, roasting, pouring, shelling, cutting, grinding, and shot blasting. In the process of silica sol shell making, it is necessary to go through multiple steps of slurry dipping, sanding, and air drying, among which sanding needs to be done in a floating sand bucket.
[0003] The existing floating sand bucket includes a column and a connecting pipe. A working chamber is arranged inside the column. A partition with a plurality of air holes is arranged horizontally in the working chamber. The partition divides the working chamber into an upper chamber and a lower chamber. The lower chamber is connected to the blower through the input end of the connecting pipe. The upper chamber is used to place the wax model. Sand is placed on the partition. The blower sprays the sand on the wax model through the air holes on the partition, and a sand shell is formed on the surface of the wax model. However, some floating sand buckets need to be manually poured and loaded, and the work efficiency is insufficient. Summary of the invention

[0018] Preferably, a grid plate is provided between the collecting chamber and the upper chamber.
[0019] By adopting the above technical solution, the grid plate can block the larger particles of sand, and then the sand falls back onto the filter screen to prepare the sand shell.
[0020] Preferably, the upper chamber is provided with a movable door above the filter screen.
[0021] By adopting the above technical solution, when there are many large-grained sands on the filter screen that affect the pores of the filter screen, the movable door can be opened to clean it.

DETAILED DESCRIPTION
[0029] The present application is further described in detail below in conjunction with the specific contents. Example
[0030] A floating sand bucket with automatic feeding function, such as Figure 1 and Figure 2 As shown, it includes a floating sand bucket body 1, in which a filter screen 2 is detachably installed, and the filter screen 2 divides the floating sand bucket body 1 into an upper chamber 3 and a lower chamber 4. A blower 5 is connected to one side of the lower chamber 4. A sand inlet pipe 31 is connected to one side of the upper chamber 3, and the other end of the sand inlet pipe 31 is connected to an automatic feeding device.
[0031] When the floating sand barrel body 1 is working, the upper chamber 3 is used to place the wax model (existing technology). The automatic feeding device blows the sand onto the filter screen 2 through the sand inlet pipe 31, and then the blower 5 is turned on to blow the sand on the filter screen 2 upward to the surface of the wax model, so that a sand shell is formed on the surface of the wax model. Among them, the holes of the filter screen 2 are small enough to prevent sand from passing through, but gas can pass through.
[0032] like Figure 1 As shown, the automatic feeding device includes an open sand hopper 6, a sand storage bucket 7 is installed at the lower end of the sand hopper 6, a pneumatic butterfly valve 8 and a solenoid valve 9 are installed between the sand hopper 6 and the sand storage bucket 7, and the solenoid valve 9 is connected to a blowing pipeline 91. The bottom of the sand storage bucket 7 is connected to the sand inlet pipeline 31.
[0033] When loading is required, the pneumatic butterfly valve 8 is started to open the channel at the bottom of the sand hopper 6, and the sand in the sand hopper 6 enters the sand storage bucket 7; then the solenoid valve 9 opens the air blowing pipe 91, and the sand in the sand storage bucket 7 is blown into the sand inlet pipe 31, and the sand enters the upper chamber 3 along the sand inlet pipe 31 and reaches the filter screen 2, completing the loading.
[0034] like Figure 3 As shown, an infrared position sensor 32 is installed on the inner wall of the upper chamber 3. The infrared position sensor 32 is electrically connected to the pneumatic butterfly valve 8 and the solenoid valve 9. The infrared position sensor 32 can sense the height of the sand on the filter screen 2. When the height drops to a set value, the infrared position sensor 32 transmits the electrical signal to the pneumatic butterfly valve 8 and the solenoid valve 9, so that the pneumatic butterfly valve 8 opens, the sand in the sand hopper 6 enters the sand storage bucket 7, and then the solenoid valve 9 opens to blow the sand onto the filter screen 2, completing the automatic feeding.
[0035] like Figure 1 and Figure 2 As shown, the filter screen 2 is installed by being placed between the upper chamber 3 and the lower chamber 4. When installing the filter screen 2, the upper chamber 3 is lifted up as a whole, and the filter screen 2 is placed on the lower chamber 4, with the edge of the filter screen 2 extending outside the lower chamber 4, and then the upper chamber 3 is placed on the lower chamber 4, and the filter screen 2 is squeezed and fixed by the upper chamber 3 and the lower chamber 4.
[0036] like Figure 1 and Figure 3 As shown, a collection assembly for collecting fine dust is provided on the upper chamber 3. The collection assembly includes collection chambers 10 provided on both sides of the upper chamber 3. The collection chambers 10 are wedge-shaped, wherein the larger end is away from the blower 5, and the collection chambers 10 are connected to the upper chamber 3. An exhaust duct 101 is connected to the side of the collection chamber 10 away from the blower 5. When the floating sand bucket body 1 is working, some fine fine dust can be sucked away through the exhaust duct 101.
[0037] like Figure 3As shown, a grid plate 102 is provided between the collecting chamber 10 and the upper chamber 3. The grid plate 102 can block the sand with larger particles, and then the sand falls back onto the filter screen 2 to prepare the sand shell.
[0038] like Figure 3 As shown, the upper chamber 3 is provided with a movable door 33 above the filter screen 2, and a lock is provided between the movable door 33 and the side wall of the upper chamber 3 for fixing the movable door 33. When there are many large particles of sand on the filter screen 2 that affect the pores of the filter screen 2, the movable door 33 can be opened to clean it.
[0039] The implementation principle of the floating sand bucket with automatic loading function in this embodiment is as follows: when the floating sand bucket body 1 is working, when the infrared position sensor 32 senses that the height of the sand on the filter screen 2 is less than the set value, the infrared position sensor 32 transmits this electrical signal to the pneumatic butterfly valve 8, opens the channel between the sand hopper 6 and the sand storage bucket 7, and the sand in the sand hopper 6 falls into the sand storage bucket 7, then the solenoid valve 9 starts the blowing pipe 91, and the sand in the sand storage bucket 7 is blown onto the filter screen 2 through the sand inlet pipe 31, completing the automatic loading.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
