Description

Technical Field

[0001] This utility model relates to the field of mold forming technology, and in particular to a mold for forming a rear light cover for a vehicle. Background Technology

[0002] As a key component of the rear of a car, the taillight cover serves multiple functions, including lighting, signal transmission, and decoration. Its molding quality affects the safety and appearance integrity of the vehicle. Most are made of transparent plastics such as polycarbonate, requiring mold forming to achieve complex curved surfaces, precise dimensions, and smooth surfaces to meet requirements for light transmittance, weather resistance, and assembly compatibility. Current molding technologies for taillight covers suffer from the problem of product damage during demolding. This stems from the unreasonable design of traditional mold demolding structures, which mostly rely on unidirectional pushing or pulling for demolding. The close fit between the cover and the inner and outer molded shells (especially in complex curved areas) generates significant friction, concentrating the demolding force locally or in a single direction. This easily leads to scratches, deformation, or even cracks on the cover surface, affecting product yield, increasing production costs, and reducing production efficiency due to the need for manual adjustments. This has become a significant obstacle to high-quality mass production. Utility Model Content

There is a rotating groove, and the lower end face of the inner molded shell 7 is located inside the rotating groove; electric telescopic rod 1 5, the upper surface of the base plate 1 is fixedly connected to the limiting plate 4, the electric telescopic rod 1 5 is fixedly connected inside the limiting plate 4, the protruding end of the electric telescopic rod 1 5 is fixedly connected to the outer molded shell 6, the outer molded shell 6 is located on the left and right sides of the inner molded shell 7; electric telescopic rod 2 9, the upper surface of the base plate 1 is fixedly connected to the support rod 2, the upper end of the support rod 2 is fixedly connected to the upper plate 3, the electric telescopic rod 2 9 is fixedly connected to the lower surface of the upper plate 3, the upper plate 3 is located directly above the inner molded shell 7, the protruding end of the electric telescopic rod 2 9 is fixedly connected to the top plate 8.

[0017] Specifically, the base plate 1 serves as the basic load-bearing component, supporting and fixing all structures. The support column 11 below it supports the base plate and facilitates operation and maintenance. The master control switch 10 controls the operation of the entire molding system. The servo motor 13, protected by the protective shell 12, drives the inner molding shell 7 to rotate via the rotating shaft 14. The lower end of the inner molding shell 7 is embedded in the rotating groove of the base plate to ensure stability, and its outer surface determines the inner contour of the lampshade. The electric telescopic rod 5 fixed by the limiting plate 4 drives the outer molding shell 6 to move left and right. The inner surface of the outer molding shell 6 cooperates with the inner molding shell 7 to form a cavity to determine the outer contour of the lampshade.

Then, molten plastic material is injected into the cavity. After that, the electric telescopic rod 29 extends to move the top plate 8 down to press against the top of the cavity. The material fills the cavity and cools and solidifies naturally to form a lampshade; after molding, the servo motor 13 drives the rotating shaft 14 to rotate the inner molded shell 7 slightly, thereby causing the solidified rear lampshade to separate from the mold wall. Then, the electric telescopic rod 15 retracts to separate the outer molded shell 6, and the electric telescopic rod 29 retracts to raise the top plate 8, moving to achieve smooth demolding.

[0018] Working principle: In the initial state, the electric telescopic rod 15 retracts to move the outer molded shell 6 away from the inner molded shell 7, and the electric telescopic rod 29 retracts to raise the top plate 8. The inner molded shell 7 is at the initial angle. After the main control switch 10 is activated, the electric telescopic rod 15 extends to push the outer molded shell 6 to engage with the inner molded shell 7, forming a mold cavity. After molten plastic is injected, the electric telescopic rod 29 extends to move the top plate 8 down to press against the top of the cavity. The raw material cools and solidifies naturally to form a lampshade. After molding, the servo motor 13 drives the inner molded shell 7 to rotate slightly to detach the lampshade. Then, the electric telescopic rod 15 retracts to separate the outer molded shell 6, and the electric telescopic rod 29 retracts to raise the top plate 8, completing the demolding.
