The second linear module (31) is fixedly installed on the base (1), and the lifting and rotating cleaning component and the dust and impurity collection component are installed on the moving end of the base (1). The lifting and rotating cleaning component is used to clean the mold cavity of the mold on both sides, and the dust and impurity collection component is used to collect the dust and impurities on the lifting and rotating cleaning component.

6. The mold visual inspection device according to claim 5, characterized in that, The lifting and rotating cleaning assembly includes a rotating cleaning assembly and a reciprocating lifting assembly. The rotating cleaning assembly is installed at the moving end of the second linear module (31), and the reciprocating lifting assembly is installed at the lower end of the rotating cleaning assembly.

7. The mold visual inspection device according to claim 6, characterized in that, The rotating cleaning assembly includes a rotating shaft (32), a brush roller (33), a first gear (34), and a first rack (35). The first gear (34) is rotatably mounted on the lower end of the moving end of the second linear module (31) via a bearing. The rotating shaft (32) is connected to the first gear (34) via a key, so that the rotating shaft (32) can slide along the axial direction of the first gear (34) and rotate synchronously with the first gear (34). A receiving groove for avoiding the rotating shaft (32) is provided on the base (1). The first rack (35) is fixedly installed on the inner wall of the receiving groove. The first gear (34) and the first rack (35) are meshed together. The brush roller (33) is fixedly installed on the upper end of the rotating shaft (32).

8. The mold visual inspection device according to claim 7, characterized in that, The reciprocating lifting assembly includes a roller (36) and a limiting guide rail (37). The roller (36) is rotatably mounted on the lower end of the rotating shaft (32), and the limiting guide rail (37) is fixedly mounted on the lower end of the base (1). The side of the limiting guide rail (37) is provided with a wave groove that is rotatably connected to the roller (36).

9. The mold visual inspection device according to claim 8, characterized in that, The dust and impurity cleaning assembly includes a desorption hood (38) and an air suction pipe (39). The two desorption hoods (38) are fixedly installed on the moving end of the second linear module (31) and located on the front and rear sides of the brush roller (33). The air suction pipe (39) is fixedly connected to the desorption hood (38) through a connector and is located on the inner side of the brush roller (33). The air suction pipe (39) is evenly provided with a plurality of air suction holes (310) facing the molds on both sides.

10. A detection method for the mold visual inspection device according to claim 9, characterized in that, Includes the following steps: Step 1: Hoist the mold onto the moving mold support assembly and the fixed mold support assembly, and control the fixed mold support assembly to move away from the moving mold support assembly through the first linear module (24) so ​​that the fixed mold and the moving mold separate; Step 2: The second linear module (31) drives the brush roller (33) to move between the fixed mold and the moving mold. During the process of moving the brush roller (33), it will move back and forth vertically and rotate at the same time, cleaning the fixed mold and the moving mold simultaneously. Dirt and impurities adhere to the brush roller (33), and when the brush roller (33) passes through the desorption cover (38), the dirt on the brush roller (33) is sucked away and collected through the desorption cover (38). Step 3: The third linear module (413) drives the vertical moving component to move between the fixed mold and the moving mold, and then the vertical moving plate (46) moves back and forth vertically. During the movement of the vertical moving plate (46), the first scanner (411) continuously shakes its head to scan the mold without dead angles, while the second scanner (412) cooperates to judge whether there are defects on the surface of the mold. Step 4: Control the distance between the fixed mold and the moving mold to increase through the first linear module (24), and apply red lead to the fixed and moving molds; Step 5: Control the fixed mold to impact the moving mold to close the mold by controlling the first linear module (24), and then observe the coloring of the parting surface of the fixed mold and the moving mold to judge their matching performance.
