Out-of-mold decoration film mechanism

Abstract

The invention discloses a film feeding mechanism for die exterior decoration. The film feeding mechanism comprises an upper closed cavity, a lower closed cavity, an upper edge pressing rim, a lower edge pressing rim, guide sleeves, guide columns, a buffering device, a guide sleeve flange, a cylinder connection flange, a hydraulic cylinder connection flange, a sealing device, a hydraulic cylinder, a hydraulic pump and a cylinder. When being fed, a thin film is placed on the upper surface of the lower cavity; a hydraulic system drives the upper cavity and the lower cavity to assemble a die; the thin film is heated to be softened, and a box body is subjected to vacuumizing, pressurization, mechanical stretching and final trimming, so that the thin film can be completely attached to a base material in a covering manner. Compared with an existing popular die interior decoration technology, the die exterior decoration technology is better in special simulation texture; the die exterior decoration technology can be applied to products with complicated structure, relatively large appearance size and relatively large stretching depth.

Description

technical field [0001] The invention relates to an appearance decoration mechanism, in particular to a film-applying mechanism focusing on out-of-mold decoration technology (OMD), which is suitable for products with complex structures, large stretching dimensions, and large stretching depths. Background technique [0002] In the past, the industry often used spray paint or water transfer printing technology to improve the defects of plastic parts. In recent years, the popular IMD (In-Mode Decoration) technology has created a richer appearance texture, but it still cannot make simulated textures (such as wood, Leather, paper and other special geometry) products. OMD out-of-mold decoration equipment is a special equipment for beautifying and pasting molds. It can generally be used in household appliances, furniture, hardware and other industries, such as the outer surface decoration of box shells, door shells, washing machines, toys, and computers in the refrigerator industry....
