Description

Technical Field

[0001] This utility model relates to the field of automatic sandblasting and cleaning technology for casting molds, and more specifically, to an automatic sandblasting and cleaning device for casting molds. Background Technology

[0002] During routine maintenance of casting molds, it is necessary to clean residual paint and rust from the cavity surface. Currently, the most common method is sandblasting. Because the shapes of cast products vary, the cavity designs of casting molds differ greatly, leading to variations in the sandblasting locations. Currently, the following two methods are mainly used for sandblasting cleaning:

[0003] (1) Manually hold a sandblasting gun to clean multiple locations inside the casting mold cavity one by one. When sandblasting, the sandblasting nozzle of the sandblasting gun needs to be kept 15-20cm away from the casting mold cavity. The position of the sandblasting gun is constantly moved and adjusted according to the sandblasting location. However, this manual cleaning is labor-intensive and inefficient.

[0004] (2) Use sandblasting equipment installed in the sandblasting room to clean multiple locations of the casting mold cavity at the same time. That is, set up multiple sandblasting heads on the top and sides of the sandblasting room to perform sandblasting cleaning at a fixed interval. However, it is inconvenient to adjust the sandblasting interval according to the different depths of the casting mold cavity, and thus the sandblasting effect is generally poor.

[0005] In addition, excessive sand accumulation in some deep cavities of the casting mold cavity during the sandblasting process affects the sandblasting effect.

[0006] In summary, the aforementioned problems exist in the current process of sandblasting to clean the coating and rust on the surface of casting mold cavities and urgently need to be solved. Utility Model Content

[0007] The purpose of this utility model is to solve the problems mentioned in the background art and to propose an automatic sandblasting cleaning device for casting molds.

[0008] The technical solution adopted by this utility model to solve its technical problem is:

[0009] An automatic sandblasting cleaning device for casting molds includes a first mounting frame, a six-degree-of-freedom robotic arm, a mounting plate, a sandblasting pipe, an air passage pipe, a sand inlet pipe, a first flexible hose, a first air compressor, a sand box, and a purging assembly.

[0010] The six-degree-of-freedom robotic arm is fixed on the first mounting frame inside the sandblasting room and is connected to a mounting plate.

[0011] The sandblasting pipe and the purging assembly are both mounted on the mounting plate and pass through the mounting plate. The bottom of the sandblasting pipe has a sandblasting port and the purging assembly is located on the side of the sandblasting port.

[0012] The air pipe connects to the inside of the sandblasting pipe, and one end of the air pipe is connected to the first air compressor via a hose.

[0013] The sand inlet pipe is inclined and connected to the inside of the sandblasting pipe;

[0014] The first hose is connected to the end of the sand inlet pipe away from the sandblasting pipe via a quick connector, and the end of the first hose is connected to the sand box.

[0015] Furthermore, the purging assembly includes a direct-fire nozzle, a second hose, and a second air compressor. The direct-fire nozzle, located on one side of the sandblasting port, is movably mounted on the mounting plate, and the direct-fire nozzle is connected to the second air compressor via the second hose.

[0016] The above solution can effectively blow away the sand accumulated in the mold cavity during the sandblasting process using the blowing component, thereby reducing the amount of sand accumulated in the mold cavity after sandblasting.

[0017] Furthermore, the six-degree-of-freedom robotic arm is connected to the mounting plate via connecting rollers.

[0018] In the above scheme, the connecting roller is used to increase the range of motion of the six-degree-of-freedom robotic arm driving the sandblasting pipe and the blowing assembly, thereby enabling an automatic sandblasting cleaning process for larger casting mold cavities.

[0019] Furthermore, the sandblasting pipe is made of ceramic.

[0020] In the above scheme, the sandblasting pipe is made of ceramic, thereby reducing the replacement frequency and extending its service life.

[0021] Furthermore, the top of the sandblasting chamber is provided with a second mounting frame and electromagnetic doors spaced apart from the second mounting frame, and a visual inspection device is provided on the second mounting frame above the electromagnetic doors.

[0022] Furthermore, the visual inspection device is one of a CCD camera, a visual camera, or a high-definition camera.

[0023] In the above scheme, after the trolley automatically enters the sandblasting chamber, the electromagnetic door opens, and the visual inspection component automatically photographs and identifies the casting mold, then feeds the results back to the controller. The controller then automatically starts the sandblasting process corresponding to the casting mold, thus enabling sandblasting of different casting mold cavities without the need for manual visual identification, reducing the error rate during operation. After the visual inspection is completed, the electromagnetic door automatically closes to protect the visual inspection component.

[0024] Compared with the prior art, the beneficial effects of this utility model are:

[0025] Compared to existing technologies, this device can automate the sandblasting cleaning and maintenance process of casting mold cavities. This effectively removes the coating and rust adhering to the cavity during the casting process, eliminating the need for manual sandblasting and significantly reducing labor intensity. Furthermore, it can be programmed to approach or move away from different parts of the cavity to improve the sandblasting effect. Additionally, during the sandblasting process, scattered sand after cleaning the coating and rust can be blown away, reducing the amount of sand accumulating in certain deep cavities of the casting mold. Therefore, this device offers superior sandblasting cleaning and maintenance for casting mold cavities. Attached Figure Description

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0033] like Figure 1 and Figure 2 As shown, an automatic sandblasting cleaning device for casting molds includes a first mounting frame 1, a six-degree-of-freedom robotic arm 2, a mounting plate 3, a sandblasting pipe 4, an air passage pipe 5, a sand inlet pipe 6, a first flexible hose 7, a first air compressor, a sand box, and a purging assembly.

[0034] The six-degree-of-freedom robotic arm 2 is fixed on the first mounting frame 1 located inside the sandblasting room, and the six-degree-of-freedom robotic arm 2 is connected to the mounting plate 3;

[0035] The sandblasting pipe 4 and the blowing assembly are both mounted on the mounting plate 3 and pass through the mounting plate 3. The bottom of the sandblasting pipe 4 has a sandblasting port and the blowing assembly is located on the side of the sandblasting port. The sandblasting port is not shown in the figure.

[0036] The air pipe 5 is connected to the inside of the sandblasting pipe 4 and one end of the air pipe 5 is connected to the first air compressor through a hose (the hose and the first air compressor are not shown in the figure. The air compressor is existing technology and its operating principle is not described).

[0037] The sand inlet pipe 6 is inclinedly installed on the sandblasting pipe 4 and is connected to the inside of the sandblasting pipe 4;

[0038] The first hose 7 is connected to the end of the sand inlet pipe 6 away from the sandblasting pipe 4 via a quick connector, and the end of the first hose 7 is connected to the sand box, which is not shown in the figure. The quick connector is shown in the figure but is not labeled.

[0039] Further refinements of the embodiments of this utility model, such as... Figure 1 and Figure 2 As shown, the purging assembly includes a direct nozzle 8, a second hose 9, and a second air compressor. The direct nozzle 8, located on one side of the sandblasting port, is movably mounted on the mounting plate 3 and is connected to the second air compressor via the second hose 9. The second air compressor is also not shown in the figure.

[0040] In a further optimization of the embodiment of this utility model, the sandblasting pipe 4 is made of ceramic.

[0041] It should be noted that the six-degree-of-freedom robotic arm 2, the first air compressor, and the second air compressor are all electrically connected to the controller, which is not shown in the figure and is specifically installed on the outer wall of the sandblasting room.

[0042] The working process of this utility model:

[0043] First, the casting mold to be sandblasted is placed on the trolley and fixed (the trolley is not shown in the figure; the fixing of the casting mold and the movement of the trolley are existing technologies and no improvements are made; after fixing, the cavity of the casting mold is placed upwards). Then, the trolley is driven into the fixed area inside the sandblasting room and the door of the sandblasting room is closed. Then, the operator selects the model of the casting mold in the controller and starts the sandblasting process (it should be noted that the sandblasting program corresponding to the cavity of each model of casting mold is preset, that is, the six free robotic arms move according to a fixed trajectory to simulate manual sandblasting).

[0044] During the sandblasting process, the six-degree-of-freedom robotic arm 2 continuously changes its position and angle according to the pre-set program to carry out an efficient sandblasting process for the casting mold cavity. At the same time, during the sandblasting process, it can blow away the scattered sand after cleaning the coating and rust, thereby reducing the amount of sand accumulated in the cavity. In addition, after sandblasting some deep cavity parts of the casting mold, the amount of sand accumulated inside is greatly reduced, thus improving the sandblasting effect.

[0045] Compared to existing technologies, this device can automate the sandblasting cleaning and maintenance process of casting mold cavities. This effectively removes the coating and rust adhering to the cavity during the casting process, eliminating the need for manual sandblasting and significantly reducing labor intensity. Furthermore, it can be programmed to approach or move away from different parts of the cavity to improve the sandblasting effect. Additionally, during the sandblasting process, scattered sand after cleaning the coating and rust can be blown away, reducing the amount of sand accumulating in certain deep cavities of the casting mold. Therefore, this device offers superior sandblasting cleaning and maintenance for casting mold cavities.

[0046] In some embodiments, such as Figure 3 and Figure 4 As shown, the top of the sandblasting room is provided with a second mounting frame 11 and electromagnetic doors 13 spaced apart from the second mounting frame 11. A visual inspection device 12 is provided on the second mounting frame 11 above the electromagnetic doors 13 (specifically, the visual inspection device 12 is one of a CCD camera, a visual camera or a high-definition camera).

[0047] Further optimizations of the above-described embodiments, such as... Figure 1 and Figure 2 As shown, the six-degree-of-freedom robotic arm 2 is connected to the mounting plate 3 via a connecting roller 10. In this embodiment, after the trolley automatically enters the sandblasting chamber, the electromagnetic door opens, and the vision inspection component automatically photographs and identifies the casting mold, then feeds the results back to the controller. The controller then controls the sandblasting process corresponding to the casting mold to automatically start and carry out the subsequent sandblasting process. In this way, sandblasting processing can be performed on different casting mold cavities without the need for manual visual identification, reducing the error rate during operation. After the vision inspection is completed, the electromagnetic door automatically closes to protect the vision inspection component. The function of the connecting roller 10 is to increase the trajectory range of the six-degree-of-freedom robotic arm 2 driving the sandblasting pipe 4 and the blowing component, thereby enabling the sandblasting cleaning process to be performed on larger casting mold cavities.
