Weather-proof high-quality car exterior trimming part injection molding positioning structure

Abstract

The invention discloses a weather-proof high-quality car exterior trimming part injection molding positioning structure. The weather-proof high-quality car exterior trimming part injection molding positioning structure comprises a stamping steel strip exterior trimming layer, a hard glue injection molding layer and an injection molding flexible glue layer which is arranged between the stamping steel strip exterior trimming layer and the hard glue injection molding layer. A bonding layer is arranged between the stamping steel strip exterior trimming layer and the injection molding flexible gluelayer, a bonding layer is arranged between the hard glue injection molding layer and the injection molding flexible glue layer, a first groove is formed in the outer portion of the hard glue injection molding layer, a positioning mechanism in fit clamping with the first groove is arranged in the first groove, in the external trimming part machining process, the flexible glue injection molding layer is added between the stamping steel strip exterior trimming layer and the hard glue injection molding layer, and due to the fact that the flexible glue injection molding layer has certain elasticity, the abnormal sounds in a car can be well solved.

Description

technical field [0001] The invention relates to the technical field of automobile exterior decorations, in particular to a weather-resistant and high-quality injection molding positioning structure for automobile exterior decorations. Background technique [0002] Exterior accessories refer to exterior decoration pendants that combine body protection and aesthetics. They are mainly used for adding after the car leaves the factory, so they can also be classified as car modification. [0003] Overmolding composite molding process is an emerging technology in the modern automobile industry. With the diversification of automobile decoration, it has attracted attention. This process combines the plasticity and flexibility of injection molded parts, and also has the dazzling appearance and strength of stainless steel and other materials.

Problems solved by technology

[0003] Overmolding composite molding process is an emerging technology in the modern automobile industry. With the diversification of automobile decoration, it has attracted attention. This process combines the plasticity and flexibility of injection molded parts, and also has the dazzling appearance and strength of stainless steel and other materials. In the new Car models are gradually being valued and used. However, when the existing exterior parts are processed, a stainless steel shell is installed on the outside of the plastic layer, but there is a certain gap between the two. This gap makes the collision between the two, although The force of the collision is small, but it will still cause abnormal noise in the car due to the collision between the two. In addition, in the existing production process, it is often necessary to clamp the skeleton in the pre-reserved position in the mold by means of positioning. Hole, the existing positioning structure is a fixed structure, and it needs to be cut later, the processing efficiency is low and the material is wasted
