Embodiment Construction

[0019] Such as figure 1 As shown, the preferred embodiment of the three-dimensional pattern forming equipment for plastic parts of the present invention includes a film feeding device 10 , a mold with a female mold 20 and a male mold 30 , and a pressing frame 40 .

[0020] The mold feeding device 10 includes a pair of film conveying wheels 12 and a pair of guiding wheels 14 . The film conveying wheel 12 is arranged upstream and downstream of the mould, and is used for pulling the film 100 . The guide wheels 14 are used to guide the conveying direction of the film 100 . The film 100 includes a substrate and a transfer layer 102 printed on the substrate. The substrate is generally made of polymer materials such as polycarbonate (PC) and polybutylene terephthalate (PBT). In the In Mold Roller (IMR) technology, the transfer layer 102 is a separate ink layer, and the ink layer is attached to the surface of the molding after molding. In the In Mold Label (IML) technique, the tran...

Abstract

A shaping method for a solid pattern of a plastic piece includes the following steps: providing a die: solid lines are arranged in the cavity of the die; providing a film: a transfer layer is arranged on the film and oil ink corresponding to the solid lines is printed on the transfer layer; pressing the film on the surface of the die: the air between the film and the die is exhausted, thereby leading the transfer layer to be correspondingly attached with the solid lines of the die; spraying glue into the cavity of the die; and separating the basic body of the film from the transfer layer. The invention also provides a shaping device which uses the shaping method for a solid pattern of a plastic piece. In the shaping method for a solid pattern of a plastic piece and the shaping device which uses the shaping method, the solid lines are formed in the die; besides, the film printed with the oil ink is jointed with the solid lines; therefore, the plastic piece with the solid pattern can be formed after glue spraying and shaping.

Description

technical field [0001] The invention relates to a molding method for forming a three-dimensional pattern on a plastic part and molding equipment using the method. Background technique [0002] Plastic parts are widely used because of their lightness and durability. In order to remind, explain or decorate, it is often necessary to print patterns on plastic parts. Adapt to such a demand, a higher degree of automation in-mold transfer (In MoldRoller, IMR) technology is adopted. The process of in-mold transfer printing technology is: first print the pattern to be printed on the film, so as to form a patterned ink layer on the film; use the film feeding machine to fit the film to the cavity of the mold, And carry out injection molding; after injection molding, the ink layer with patterns is separated from the film. After the film is peeled off, a plastic part with patterns printed on it is obtained. [0003] However, the use of in-mold transfer printing technology can only fo...
