The Sealing Structure of Gas-Assisted Injection Molding Process Hole on Automobile Door Handle

Abstract

The invention relates to a sealing structure for a gas-assisted injection molding process hole on an automobile door handle, including a door handle, and the door handle has a gas-assisted injection molding process hole, and is characterized in that it also includes a sealing structure for sealing the gas-assisted injection molding process hole Blocking cover, the blocking cover includes a main body and a cap part which are integrally arranged, the main body is used to plug into the gas-assisted injection molding process hole, the outer diameter of the cap part is larger than the aperture of the gas-assisted injection molding process hole, and the cap part There is a circle of plugging welding wire that can be melted under ultrasonic high-frequency vibration on the lower surface of the lower surface. In the molten state, the blocking cover and the door handle are welded together. The invention has simple structure and convenient operation, can ensure that the gas-assisted injection molding process hole on the automobile door handle remains sealed during the electroplating process, ensures the electroplating quality, improves the yield rate of the handle electroplating, avoids cross-contamination accidents of electroplating solutions, and reduces losses of electroplating manufacturers.

Description

technical field [0001] The invention relates to a sealing structure for a gas-assisted injection molding process hole on an automobile door handle, and belongs to the technical field of automobile assembly. Background technique [0002] With the development of the economy, cars have become a common means of transportation for people. The market demand for cars continues to increase, and customers have higher and higher requirements for all aspects of cars. The durability and aesthetics of car door handles have also been recognized by customers. focus of attention. [0003] In order to ensure the strength of the car handle and control the manufacturing cost of the car door handle, an advanced gas-assisted injection molding process is usually used to produce the door handle, which can solve both the strength problem and the material cost problem of the car door handle. In order to make the appearance of the car door handle more beautiful, we electroplate a layer of light chro...

Problems solved by technology

Rubber plug 4 is usually used now to block gas-assisted injection molding process hole 1a (such as figure 2 shown), but this plugging method has the following disadvantages: Because there will be temperature difference changes during the electroplating process, the rubber plug will expand with heat and contract with cold, and the plugging effect is very poor, which will easily cause the hollow door handle cavity to be filled with electroplating chemicals. The potion will overflow in other subsequent electroplating stages. After the potion overflows, it will first flow to the surface of the door handle, forming unremovable stains, missing plating, and other defects; secondly, it will cause the potions of different cylinders to mix, appearing Cross-contamination accidents cause pollution to the electroplating pool, causing the potion to be invalidated and causing great losses
