Description

Technical Field

[0001] The utility model relates to the technical field of mold auxiliary equipment, in particular to a rust removal device used for cleaning the surface of a mold. Background Art

[0002] Molds are tools used in industrial production to manufacture products by methods such as injection molding, blow molding, extrusion, smelting, and stamping. Molds are basically made of metal materials. After a period of use, the outer surface of the metal material will wear out, causing the oxide layer on the surface of the metal mold to be damaged, thus causing the metal mold to rust.

[0003] Traditional mold rust removal methods are basically done by manual brushing, which is inefficient and greatly increases the labor intensity of operators. A metal mold surface rust removal and polishing device disclosed in the Chinese utility model patent No. 202022919323.4 uses a motor-controlled grinding wheel rotation and a motor-controlled mold rotation structure to evenly grind and polish the surface of the mold. Although it can achieve the effect of surface rust removal of the mold, it still has the following technical defects:

[0004] 1. The rust removal and polishing components composed of multiple sets of motor grinding wheels result in high equipment cost investment;

[0005] 2. Due to the shape and size of the grinding wheel, the rust in some gaps on the mold surface cannot be polished away.

[0006] Therefore, it is necessary to research and develop a rust removal device with low cost and good rust removal effect for rust removal of mold surface. Summary of the invention

[0007] The utility model aims to provide a rust removal device for cleaning the surface of a mold, which can improve the rust removal effect and efficiency while reducing the manufacturing cost of the rust removal device.

[0008] In order to achieve the above purpose, the utility model provides a rust removal device for cleaning the mold surface, and the specific implementation scheme is as follows:

[0010] A workbench, a top surface of which is formed with a mounting surface;

[0011] A containing barrel is arranged on the mounting surface and has a rust removal cavity formed therein;

[0012] An ultrasonic generator is arranged on the inner wall of the rust removal chamber;

[0013] A positioning frame, arranged at the bottom of the rust removal chamber, for fixing the mold;

[0014] A first mechanical arm is disposed on the mounting surface, and a cleaning component is disposed on a movable end thereof, wherein the cleaning component can cover the top of the containing barrel and spray a chemical rust removal solvent or a high-pressure liquid into the containing barrel;

[0015] The second mechanical arm is arranged on the installation surface, and a drying component is arranged on the movable end of the second mechanical arm. The drying component can cover the top of the containing barrel to transport high-temperature gas into the containing barrel.

[0016] The utility model discloses a rust removal device for cleaning the surface of a mold. Compared with the prior art, a accommodating barrel with a rust removal chamber is arranged on the installation surface of a workbench, a positioning frame for fixing the mold is arranged at the bottom of the rust removal chamber, and then an ultrasonic vibrator is arranged on the inner wall of the rust removal chamber. A first mechanical arm and a second mechanical arm are arranged on the installation surface of the workbench, a cleaning component that is covered with the accommodating barrel is arranged on the first mechanical arm, and a drying component that is covered with the accommodating barrel is arranged on the second mechanical arm. When actually used, the mold is first fixed in the rust removal chamber by using the positioning frame, and then the cleaning component is covered on the accommodating barrel by using the first mechanical arm, and then the cleaning component injects a chemical rust removal solvent into the rust removal chamber to soak the mold, so that the metal rust on the surface of the mold reacts chemically with the chemical rust removal solvent.
