Injection-molded part vacuum lamination decoration forming structure and method

Abstract

The invention relates to the field of automobiles, in particular to an injection-molded part vacuum lamination decoration forming structure and method. An injection-molded part is placed on a lower die plate, then a heated membrane is placed in a die, and an upper pressing plate drives an upper die plate to move to the lower die plate; after the upper die plate and the lower die plate are combined, a vacuumizing mode of a lower vacuuming structure in the lower die plate is started, and the heated membrane is sucked instantly so as to be pasted to the surface of the injection-molded part; the adhesive face of the membrane is well pasted to the molded surface of the injection-molded part along with the shape structure of the injection-molded part, a reverse edge laminated corner can be formed by the membrane along with the shape structure of the injection-molded part; and the upper die plate is moved away after cooling, and a formed decoration product is taken out. The injection-molded part vacuum lamination decoration forming structure and method have the beneficial effects that the injection-molded part vacuum lamination decoration forming method is provided and is especially suitable for manufacturing high-grade injection-molded part vacuum lamination decoration, wherein the R angle is smaller than 0.5 MM, the height is larger than 30 MM, the peripheral demolding inclination is too small, and the decoration face of a decoration piece is required to have the high three-dimensional effect and concave-convex texture with certain sense of touch, or the method is suitable for manufacturing high-grade injection-molded part vacuum lamination decoration with a part of reverse edge needing lamination decoration.

Description

technical field [0001] The invention relates to the field of automobiles, and relates to a vacuum film-coated decoration molding structure and method for an injection molded part. Background technique [0002] A survey on car sales in 4S stores shows that when a car is sold, the most critical moment for the car owner to make a decision is the 7 seconds after opening the door-the perception of the interior, which is common both at home and abroad. Same. In order to design a more ideal car interior, designers are constantly digging new materials and exploring the combination of various design schemes to make the interior design of the car more harmonious with the driver. This requires that the comfort, attractiveness, durability, and practicality of automotive interiors be closer to the needs of consumers. Many new injection molding processes, such as in-mold hot stamping transfer, insert heat transfer injection molding and other decorative processes have also emerged. [0...
