Description

Technical Field

[0001] This utility model relates to the field of plasma activation treatment technology, specifically to a plasma activation treatment device for mold surface. Background Technology

[0002] As a core tool used in industrial production to shape products, the surface properties of molds directly affect the quality of the products, production efficiency, and the service life of the molds. In processes such as injection molding, die casting, and stamping, the mold surface must possess good wear resistance, corrosion resistance, release properties, and compatibility with the product material. For example, if the release properties of an injection mold surface are poor, it can easily lead to product sticking and deformation, increasing the defect rate; if the corrosion resistance of a die casting mold surface is insufficient, its service life will be shortened due to the erosion and corrosion of molten metal. Therefore, targeted treatment of the mold surface to optimize its performance is a crucial step in industrial production.

[0003] For example, Chinese utility model patent application number 202223390919.5 discloses a plasma activation pretreatment device for glass, including a rotating housing and two plasma spray guns. The spray guns rotate around a fixed axis to form an annular spraying area, reducing the number of spray guns and increasing the coating area, significantly improving the pretreatment efficiency of glass texturing, reducing the number of plasma spray guns, increasing the coating area and processing efficiency, and having the advantages of simple structure, low cost and easy promotion. However, the device still has certain shortcomings; When plasma activation is performed on parts, if the surface of the parts is not cleaned, dust, oxide scale and other contaminants often adhere to the surface of the parts. These substances act as a barrier, preventing the plasma from directly contacting the surface of the parts. This makes it difficult for the active particles in the plasma to fully react with the surface molecules of the parts, and it is difficult to effectively break the surface molecular bonds and introduce polar groups.

[0004] Therefore, we propose a plasma activation treatment device for mold surfaces to solve the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a plasma activation treatment device for mold surfaces, in order to solve the problem mentioned in the background art that, when performing plasma activation treatment on parts in the current market, the surface of the parts is not cleaned, and the surface of the parts is often covered with dust, oxide scale and other contaminants. These substances act as a barrier, preventing the plasma from directly contacting the surface of the parts, making it difficult for the active particles in the plasma to fully react with the surface molecules of the parts, and making it difficult to effectively break the surface molecular bonds and introduce polar groups.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a plasma activation treatment device for mold surface, comprising a support frame and a plasma spraying assembly. Connecting strips are installed on the upper left and right sides of the support frame, and a conveying mechanism is provided between the connecting strips. Support columns are installed above the connecting strips, and movable strips are installed above the support columns via hydraulic rods. A groove is formed on the front surface of the movable strip, and a reciprocating screw is provided inside the groove. A slider is installed on the reciprocating screw, and a plasma spraying assembly is installed on the front surface of the slider. A right-angle bracket is mounted on the front surface of the plasma spraying assembly, a dust removal pump is mounted on the front surface of the support column on the left side, a cleaning brush is mounted on the upper surface of the right-angle bracket, and a strong magnetic block is embedded in the upper surface of the cleaning brush. The strong magnetic block is magnetically connected to the right-angle bracket.

[0007] Preferably, the upper surface of each support column is equipped with a guide rod, the guide rod passes through the movable bar, the movable bar is slidably connected to the guide rod, and the surface of the conveying mechanism is treated with anti-slip treatment.

[0008] With the above structural design, the guide rod on the support column passes through the movable strip, and the movable strip slides along the guide rod, which restricts the lifting trajectory of the movable strip, avoids deviation, and ensures that the plasma spraying component maintains a precise distance from the mold surface.

[0009] Preferably, a servo motor is installed on the left side of the movable bar, and the right side of the servo motor is connected to a reciprocating lead screw via an output shaft.

[0010] With the above structural design, the servo motor on the left side of the movable bar drives the reciprocating lead screw to rotate. Through the cooperation between the lead screw and the slider, the slider and the plasma spraying assembly move back and forth along the slide, realizing automated and uniform spraying. The conveying mechanism drives the mold to move slowly, realizing full spraying of the mold.

[0011] Preferably, a plasma activation processor is installed on the left side of the support frame, and the plasma activation processor is connected to the plasma spraying assembly through a connecting pipe, which has a telescopic structure design.

[0012] With the above structural design, the plasma activation processor on the left side of the support frame generates plasma, which is then delivered to the plasma spraying assembly through a retractable connecting tube. The connecting tube extends and retracts with the movement of the slider, without obstructing the operation of the equipment and ensuring a stable plasma supply.

[0013] Preferably, a dust extraction pipe is installed above the dust pump, and a dust extraction nozzle is installed below the dust extraction pipe. The dust extraction nozzle is located below the right-angle frame, and the dust extraction pipe has a telescopic structure design.

[0014] With the above structural design, the dust pump extracts dust and impurities cleaned by the cleaning brush through the dust extraction pipe and dust extraction nozzle.

[0015] Preferably, the cleaning brush has limit plates installed on both the front and rear sides of its upper surface, and fastening bolts are installed on the limit plates, which are threadedly connected to the right-angle bracket.

[0016] With the above structural design, the limiting plate on the cleaning brush is connected to the right-angle bracket by fastening bolts to fix the cleaning brush, prevent it from loosening during cleaning, and facilitate disassembly and replacement.

[0017] Preferably, threaded rods are installed on both the left and right sides of the slider, and threaded sleeves are installed on both threaded rods. An abutment block is installed on the opposite end of each threaded sleeve. Protective pads are installed on both the left and right sides of the inner wall of the slide groove. Both the abutment block and the protective pad are designed with a circular structure, and the center line of the abutment block and the center line of the protective pad coincide with each other.

[0018] With the above structural design, the threaded sleeves on the threaded rods on both sides of the slider can adjust the position of the abutment block. When the slider moves to both ends of the slide groove, the abutment block contacts the protective pad, buffers the impact force, protects the equipment parts, and extends the service life. Thus, the distance the slider moves left and right can be adjusted according to the width of the mold, reducing empty spraying.

Enhance equipment stability and applicability, and extend service life. The movable strip slides along the guide rod, and in conjunction with the hydraulic rod, precisely adjusts the height of the plasma spraying component; the servo motor drives the reciprocating screw to move the slider smoothly, achieving automated and uniform spraying.
