Sealed structure for gas aided injection molding technological hole of automobile door handle

Abstract

The invention relates to a sealed structure for a gas aided injection molding technological hole of an automobile door handle. The sealed structure comprises a door handle, and is characterized by further comprising a blocking cover used for blocking the gas aided injection molding technological hole, wherein the gas aided injection molding technological hole is formed in the door handle; the blocking cover comprises a main body part and a cap part which are integrally arranged; the main body part is used for being plugged into the gas aided injection molding technological hole; the outer diameter of the cap part is greater than the opening diameter of the gas aided injection molding technological hole; a circle of blocking cover welding wire capable of fusing under the ultrasonic high-frequency vibration is arranged on the peripheral edge of the lower surface of the cap part; the blocking cover is buckled on the hole edge of the gas aided injection molding technological hole; the blocking cover welding wire is fused under the ultrasonic high-frequency vibration to weld the blocking cover with the door handle. According to the invention, the structure is simple, the operation is convenient, the gas aided injection molding technological hole of the automobile door handle can be kept sealed during the electroplating process, the electroplating quality is ensured, and the yield of the handle electroplating is improved; the electroplate liquid cross contamination accident is avoided, and the loss of the electroplating factory is reduced.

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
