Problems solved by technology

[0007] As a decorative surface, the decorative bright surface has very high requirements on the quality of the surface. During the production and transportation of the decorative bright surface of the outer water-cut sealing strip, if the protection is not good, it will cause certain scratches and scratches on the decorative bright surface. question
Reduced production efficiency, customer complaints
[0008] Whether it is an assembled bright surface water-cut sealing strip or a co-extruded bright surface water-cut sealing strip, a thin layer of protective film will be pasted on the decorative surface for protection during production and transportation, increasing the preparation process and increasing manufacturing cost
[0009] During the production process, the mold switching time of the bright surface water-cut sealing strip and the black surface water-cut sealing strip also causes a decrease in production efficiency

Embodiment 1

[0048] The outer water-cut sealing strip of the automobile, the outer water-cut sealing strip is composed of a metal skeleton 3 and a coated soft rubber 4, and the metal skeleton 3 is wrapped by the coated soft rubber 4 and extruded together, and the metal skeleton 3 faces The outer part of the car constitutes the decorative bright surface 6, and the decorative bright surface 6 is covered with a layer of bright surface protective glue 7, which can be kept until the water-cut sealing strip outside the main engine factory is installed and removed, reducing the production and transportation process. Quality defects such as scratches and scratches on the decorative bright surface 6 have realized the protection of the decorative bright surface 6 during the production and transportation of the co-extruded bright surface water-cut sealing strip; the two ends of the bright surface protective glue 7 and the coated A V-shaped mouth with an angle of about 30° is formed when the junction o...

Embodiment 2

[0051] A kind of co-extrusion process of water-cut sealing strip for automobile, specifically comprising the following steps,

[0052] Step 1: Determine whether to produce the water-cut sealing strip on the bright surface or the water-cut sealing strip on the black surface;

[0053] Step 2: If the water-cut sealing strip outside the bright surface is produced, the adhesive glue is coated on the surface of the metal frame 3 outside the A area, and the coated soft rubber 4 outside the A area is firmly bonded to the metal frame 3 after extrusion molding. And the bright surface protective glue 6 on the A area and the decorative bright surface 6 on the metal frame 3 have poor adhesion; Glue solution, after extrusion molding, the bright surface protective glue 6 on the A area and the coated soft glue 4 outside the A area are firmly bonded to the metal skeleton 3;

[0054] Step 3: After the product processing or assembly is completed, tear off the bright surface protective glue 7 to...

Abstract

The invention discloses an automobile outer water-cut sealing strip and a co-extrusion process, which comprises a car door outer panel, a car door inner panel and a car door glass, and the top of the car door outer panel wraps the car door inner panel, and is characterized in that it also includes an outer water-cut sealing strip, And the door glass is in contact with the outer water-cut sealing strip. The outer water-cut sealing strip is composed of a metal skeleton and a soft rubber coating. The metal skeleton is wrapped by the soft rubber and extruded together. The metal skeleton faces the outside of the car. Part of it constitutes a decorative bright surface, and the decorative bright surface is covered with a layer of bright surface protective glue; the coated soft glue is provided with a soft glass glue facing the inside of the car, which realizes the production and transportation of the co-extruded water-cut sealing strip outside the bright surface. The protection of the decorative bright surface during the process, and the rapid switching of the water-cut sealing strip on the bright surface and the water-cut sealing strip on the black surface during the production process, improve the production efficiency of product changeover.

Description

technical field [0001] The invention belongs to the technical field of automobile parts manufacturing, in particular, the invention relates to an automobile exterior water-cut sealing strip and a co-extrusion process. Background technique [0002] The outer water cut sealing strip is one of the important sealing parts of the car. It is installed on the outside of the door and window, and has the functions of dustproof, waterproof, noiseproof and appearance decoration. As an exterior decoration, it can satisfy different decoration styles by choosing different materials and colors of the exterior surface, so the requirements for its appearance are relatively high. [0003] At present, there are mainly two types of outer water-cut sealing strips on the market: black decorative strips and high-gloss decorative strips. Among them, high-gloss decorative strips include stainless steel high-gloss decorative strips, aluminum high-gloss decorative strips and colored high-gloss decora...
