[0021] The technical solution of this utility model will be further described in detail below with reference to specific embodiments.

[0022] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0023] Example

[0024] A die-casting sandblasting device with automatic abrasive recovery, such as Figures 1-4 As shown, the device includes a sandblasting device body 1, the upper half of which is a sandblasting chamber, and the lower half of which is a recovery chamber. An annular ventilation chamber is provided between the sandblasting chamber and the recovery chamber. A collection mechanism 3 is provided on the ventilation chamber. A drive mechanism 4 is provided at the rear end of the sandblasting device body 1. A sandblasting mechanism 5 is provided on the drive mechanism 4. A recovery box 2 is slidably provided in the recovery chamber of the sandblasting device body 1. The shell of the recovery box 2 away from the sandblasting device body 1 is a transparent shell, and a handle is provided on the transparent shell.

[0025] The parts to be processed are placed in the sandblasting chamber, and then the drive mechanism 4 is used to drive the sandblasting mechanism 5 to move and sandblast the parts. During the sandblasting process, the collection mechanism 3 is used to generate negative pressure inside the sandblasting device body 1, and the sand generated by sandblasting is collected on the recycling box 2 in the recycling chamber of the sandblasting device body 1, so that the sand can be recycled and processed again later.

[0026] This device is further configured such as Figures 1-3 As shown, the collection mechanism 3 includes a connecting pipe 9. The air exchange chamber of the sandblasting device body 1 is provided with several mounting holes in the circumferential direction. The connecting pipe 9 is detachably installed in the holes. A filter plate 10 is detachably installed at the end of the connecting pipe 9 near the sandblasting device body 1.

[0027] The collection mechanism 3 also includes an air extractor 7, which is mounted on the rear end of the main body 1 of the sandblasting device via a bracket. The air intake of the air extractor 7 is connected to the connecting pipe 9 via a connecting pipe 8.

[0028] A baffle 11 is installed at the junction of the air exchange chamber and the recovery chamber of the main body 1 of the sandblasting device. The cross-section of the baffle 11 is an acute triangle. When the air extractor 7 is started, air is drawn in through the connecting pipe 8 and the connecting pipe 9, creating a negative pressure inside the main body 1 of the sandblasting device. This negative pressure treats the sand on the sandblasting chamber, causing it to sink into the collection mechanism 3 through gravity and negative pressure, thus improving the recovery efficiency. The filter plate 10 prevents sand from entering the air extractor 7 and facilitates disassembly and replacement. The baffle 11 reduces the probability of sand moving upwards from the bottom.

[0029] This device is further configured such as Figure 2 As shown, the sandblasting device also includes a support plate 6, which is arranged in the spray chamber of the main body 1 of the sandblasting device.

[0030] This device is further configured such as Figure 1 , Figure 4 As shown, the sandblasting mechanism 5 includes a lifting shell 16. The top of the lifting shell 16 has a feed inlet and a conveying channel. A rotating seat 17 is detachably mounted circumferentially on the inner side of the lifting shell 16. A sandblaster 18 is rotatably mounted on the rotating seat 17 via a limiting structure. The structure and working principle of the sandblaster 18 are existing technologies and will not be described in detail here. The sandblaster 18 is connected to the conveying pipe. By adjusting the pitch angle of the sandblaster 18 using the limiting structure, the sandblasting angle can be adjusted as needed. Then, sand is fed into the feed inlet of the lifting shell 16 using a feeding device. The sand enters the sandblaster 18 through the conveying pipe, and the sandblaster 18 is driven to perform sandblasting treatment on the accessories.

[0031] This device is further configured such as Figure 1 , Figure 2 , Figure 4 As shown, the drive mechanism 4 includes a slide rail 12, which is installed at the rear end of the sandblasting device body 1. A screw 14 is rotatably installed inside the slide rail 12. A stepper motor 13 is installed at the end of the slide rail 12 away from the sandblasting device body 1. The output end of the stepper motor 13 is connected to the screw 14.

[0032] The sandblasting mechanism 5 is slidably mounted on the screw 14 via the slide block 15, and the slide block 15 is fixedly mounted on the top of the rear end of the lifting housing 16.

[0033] Working principle: The pitch angle of the sandblaster 18 is adjusted by using a limiting structure. Then, the sand is put into the feed port of the lifting shell 16 by using a feeding device. The parts to be processed are placed in the sandblasting chamber. The sandblaster 18 is driven to sandblast the parts. During the sandblasting process, the stepper motor 13 drives the screw 14 to rotate, so that the sandblasting mechanism 5 moves vertically to sandblast the surface of the parts. At the same time, the air pump 7 is started to draw air through the connecting pipe 8 and the connecting pipe 9, so that negative pressure is generated in the main body 1 of the sandblasting device. The sand on the sandblasting chamber is subjected to negative pressure treatment. By gravity and negative pressure, the sand sinks to the collection mechanism 3, realizing automatic recovery of abrasive.

[0034] The above are merely preferred embodiments of this utility model. For parts that do not require creative effort in circuit control, signal control and transmission, please refer to the prior art. However, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and utility model concept of this utility model, should be included within the protection scope of this utility model.
