Description

Technical Field

[0001] The utility model relates to the field of mold sand processing, in particular to a mold sand processing device. Background Art

[0002] Sandblasting is a process for surface treatment of workpieces. Compressed air is used as the power to form a high-speed jet beam to spray the material (copper ore sand, quartz sand, corundum, iron sand, sea sand) at high speed onto the surface of the workpiece to be treated, so that the appearance or shape of the workpiece surface changes. Due to the impact and cutting action of the abrasive on the workpiece surface, the surface of the workpiece obtains a certain degree of cleanliness and different roughness, and the mechanical properties of the workpiece surface are improved, thereby improving the fatigue resistance of the workpiece, increasing the adhesion between it and the coating, extending the durability of the coating, and also facilitating the leveling and decoration of the coating. Mold sandblasting refers to the process of spraying special abrasives onto the mold surface by mechanical or chemical means to achieve the effects of enhancing mechanical strength, improving surface quality, and extending the service life of the mold.

[0003] For example, a sand processing equipment for molds disclosed in the utility model with authorization announcement number CN220241157U, through the setting of two clamping components and the transmission connection between one of the clamping components and the conveying component, can clamp and flip the mold during the sandblasting process, thereby improving the comprehensiveness of its sand processing.
