Description

Technical Field

[0001] The utility model relates to a vehicle, and more particularly to a multi-color injection-molded automobile ornament. Background Art

[0002] For multi-color injection molded automotive accessories, the first shot is usually used to mold the skeleton, and the second shot and subsequent shots are used to mold the appearance layer. The second shot and subsequent shots may have different requirements for different materials, colors, and leather textures. If there are two or more adjacent appearance layers, it is easy to cause problems such as color mixing or unclear boundaries. Especially when the appearance layer is a soft material (such as a thermoplastic elastic material), this is because the melting point of soft materials is generally low. When multiple appearance layers are injected in sequence, it is very easy for the previous appearance layer to be melted and damaged, resulting in appearance problems such as lack of material.

[0003] One solution known in the prior art is to design isolation grooves between multiple appearance layers. However, this solution has high requirements on the mold and is also limited by the grooves in appearance. In particular, when the appearance layer is made of soft material, the appearance layer corresponding to the isolation groove often collapses and has poor appearance.

[0004] Another solution known in the prior art is to pre-inject a transparent layer between the second shot and subsequent multiple appearance layers. However, this solution has the disadvantages of complex process and high cost. Utility Model Content
