An automatic sandblasting device for mold processing

Abstract

The invention provides an automatic sand blasting device for mold machining. The automatic sand blasting device comprises a box body, a push-over mechanism, a power mechanism, a sand blasting mechanism, a timer and a controller. Multiple mold positioning grooves are formed in the inner side of a bottom plate of the box body and distributed in a circumferential direction. The push-over mechanism is arranged in the box body. The push-over mechanism comprises multiple sliding blocks. The portion, close to one side of the corresponding mold positioning groove, of each sliding block is provided with a push rod for pushing over molds. The power mechanism is used for driving the sliding blocks to move on the bottom plate of the box body in the radial direction of the circumference where the sliding blocks are located. The sand blasting mechanism comprises multiple sand blasting assemblies. The sand blasting assemblies and the mold positioning grooves are the same in number and are arranged in a one-to-one manner. The controller is connected with the power mechanism, the sand blasting mechanism and the timer and controls the actions of the power mechanism, the sand blasting mechanism and the timer. According to the automatic sand blasting device for mold machining, the push-over mechanism, the power mechanism and the sand blasting mechanism are controlled automatically through cooperation of the timer and the controller, continuous sand blasting of the molds is achieved, and sand blasting is uniform and thorough.

Description

technical field [0001] The invention relates to the technical field of sandblasting, in particular to an automatic sandblasting device for mold processing. Background technique [0002] Sandblasting machine is a kind of mechanical equipment that can spray abrasives onto the surface of the mold with the help of compressed air power. The abrasive is sprayed at high speed to the surface of the mold to be treated for impact grinding, so that the shape or shape of the outer surface of the mold surface changes. Due to the impact and cutting effect of the abrasive on the surface of the mold, the surface of the mold obtains a certain degree of cleanliness and different roughness The degree improves the mechanical properties of the mold surface, thus improving the fatigue resistance of the mold, increasing the adhesion between it and the coating, prolonging the durability of the coating film, and is also conducive to the leveling and decoration of the coating. The existing mold sand...

Problems solved by technology

The existing mold sanding machine is manual sandblasting. People hold a sandblasting gun to manually sandblast the tire mold in the sandblasting cabin. The manual sandblasting process is uneven, causing great damage to the edges and corners of the mold, and high labor intensity. Low production efficiency and will cause harm to the health of workers
