Description

Technical Field

[0001] The utility model relates to the technical field of sealing component equipment, and particularly relates to a sealing component used in the anodic oxidation surface treatment process of aluminum die-castings. Background Technique

[0002] Anodic oxidation is the electrochemical oxidation of metals or alloys. Aluminum and its alloys, under the action of an applied current in a corresponding electrolyte and specific process conditions, form an oxide film on the aluminum product (anode) during the anodic oxidation process. If not specifically specified, anodic oxidation usually refers to sulfuric acid anodic oxidation. When aluminum die-castings are placed in an oxidation tank for oxidation, in order to prevent sulfuric acid from entering the inner cavity of the aluminum die-castings and causing internal corrosion during the anodic oxidation on the surface of the aluminum die-castings, generally, stoppers such as wooden plugs are stuffed into the holes on the outer wall of the aluminum die-castings to seal them and prevent sulfuric acid from entering. After the aluminum die-castings are oxidized, the stoppers are not easy to remove, and the sealing effect is not good.

[0003] The application number is CN202021690953.2, which discloses a sealing component used in the anodic oxidation surface treatment process of aluminum die-castings, belonging to the technical field of sealing components. It includes a handle. A fixing rod is fixedly connected to the lower surface of the handle. A fixing plate is fixedly installed below the fixing rod. A rubber plug is embedded in the fixing plate. A first collar is welded to the outer wall of the rubber plug. Connecting rods are fixedly installed on the left and right sides of the first collar respectively. Sleeves are fixedly installed on the left and right sides of the two connecting rods respectively. A rotating shaft is embedded in the fixing plate. A fixing frame is movably connected below the rotating shaft. The lower surface of the rubber plug is movably connected to the aluminum die-casting body. Through the sealing ring on the upper surface of the fixing frame, the sealing ring is in a semi-circular arc shape. When the two sealing rings are closely attached, they form a circle, surrounding the outer wall of the aluminum die-casting body and closely attaching to seal the aluminum die-casting body to prevent sulfuric acid from entering through the holes on the lower surface of the aluminum die-casting body.

[0004] The following defects exist in the sealing component disclosed in the above document used in the anodic oxidation surface treatment process of aluminum die-castings: When the sealing component is in use, when the casting is impacted, the casting will shake in the sealing component. At this time, it is necessary to fix the casting and the positioning component, otherwise it may cause the sealing component to fall off the positioning component when the casting shakes.

[0005] It can be seen that the existing sealing component does not have a function of fixing and limiting the positioning component and the outside of the casting. It is necessary to improve the existing deficiencies and provide a function that can fix and limit the positioning component and the outside of the casting. Content of the Utility Model

[0006] The purpose of the utility model is to provide a sealing component used in the anodic oxidation surface treatment process of aluminum die-castings to solve the problems raised in the above background technique.

A positioning ring is sleeved on the side of the four blocks that is closer. A spring is provided on the outer wall of the collar. The tops of the four blocks are located on the inner wall at the bottom of the spring. The purpose of such a setting is that during the use of this sealing component, the rubber ring part of this component is sleeved into the positioning component and fixed in the positioning component through a threaded groove. The casting is inserted into the positioning ring. The positioning ring pushes the tops of the blocks outwards. The blocks limit the periphery at the bottom of the spring. At this time, the connecting ring is on the outer wall of the casting. The connection between the connecting ring and the casting is fixed through a sealing ring. The collar is connected to the sleeve block. The sealing ring in the sleeve block seals the connection between the sleeve block and the sleeve. The fixing ring and the positioning component are fixed in the air vent groove of the sleeve block through a snap ring, so that the casting is fixed on the positioning component. When the casting shakes, the vibration is conducted inwards to the sleeve block. The sleeve block conducts the vibration to the air vent groove through the gap. The air vent groove slows down the vibration. The spring and the connecting ring limit the outside of the casting, reducing the shaking amplitude of the casting and increasing the stability of this sealing component.

[0009] Furthermore, a connecting ring is welded to the top of the spring. A sealing ring is sleeved on the inner walls of the collar and the connecting ring. The purpose of such a setting is that during the use of this sealing component, the casting is inserted into the positioning ring. The positioning ring pushes the tops of the blocks outwards. The blocks limit the periphery at the bottom of the spring. At this time, the connecting ring is on the outer wall of the casting. The connection between the connecting ring and the casting is fixed through a sealing ring.

[0010] Furthermore, the sealing structure includes a fixing ring. A rubber ring is sleeved on the outside of the fixing ring. A threaded groove is provided on the outer wall of the rubber ring. The purpose of such a setting is that during the use of this sealing component, the rubber ring part of this component is sleeved into the positioning component and fixed in the positioning component through the threaded groove.

[0011] Furthermore, a snap ring is welded to one end of the fixing ring. A gap is provided on the outer walls around the snap ring. The purpose of such a setting is that during the use of this sealing component, when the casting shakes, the vibration is conducted inwards to the sleeve block. The sleeve block conducts the vibration to the air vent groove through the gap. The air vent groove slows down the vibration.

[0012] Further, the other end of the snap ring is provided with a sleeve block. An air vent groove is formed in the outer wall of the sleeve block close to the snap ring, and the sleeve block is sleeved on the outer wall of the snap ring through the air vent groove. The purpose of such a setting is that during the use of this sealing assembly, the fixing ring and the positioning assembly are fixed in the air vent groove of the sleeve block through the snap ring, so that the casting is fixed on the positioning assembly.

[0013] Further, the sleeve ring is sleeved on the outer walls around the sleeve block, and the inner ring sealing ring of the sleeve ring is connected to the snap ring. The purpose of such a setting is that during the use of this sealing assembly, the sleeve ring is connected to the sleeve block. The sealing ring in the sleeve ring seals the connection between the sleeve block and the sleeve ring. The fixing ring and the positioning assembly are fixed in the air vent groove of the sleeve block through the snap ring, so that the casting is fixed on the positioning assembly.
