Car headlight decoration frame is one of the most important parts on the headlights, the appearance requirements are strict, the mold needs to be electroplating treatment.
For the car headlight decoration frame mold, the design should pay attention to the following points:
(1) Electroplated parts should first avoid welding wire, because electroplating parts have any fusion wire will appear, affect the appearance of plastic parts, design pouring system to avoid melting wire, if the welding wire is inevitable, try to drive it to the non-appearance area, pouring system design through the mold flow analysis verification.
(2) The surface of the decorative frame is generally designed with a pattern. The depth of the plastic pattern should be paid attention to when designing the mold, which is generally easy to produce running lines.
3) The molding process scope of plastic parts is small, and the surface of plastic parts is easy to produce bright spots and difficult to control.
When the mold pouring system is designed, the flow channel should be thick and large. The gate gate adopts fan-shaped gate, and the largest gate width is about 35~40mm, which is conducive to melt filling.
(4)Decorative frame plastic parts is easy to appear the phenomenon of adhesive mold, the solution of the early design of adhesive mold of plastic parts is generally:
a. The inverted grain is designed on the inner side of the plastic parts with easy adhesive mold wrap. The depth of the inverted grain is 0.5~1mm, and the inverted pattern is designed near the rounded corners of the plastic parts.
b. The inner side of the plastic parts is designed where the mold force is large, and the inverted hook is designed on the push rod.
