Problems solved by technology

[0011] That is, in the conventional transfer molding method, since the alignment of the transfer film is performed based on the positions of the marks for the longitudinal direction and the marks for the width direction attached to the transfer film, by repeating the transfer In the forming process, there will be a problem of shifting the position of the transferred pattern

Embodiment Construction

[0063] Before continuing the description of the present invention, in the drawings, the same reference numerals are assigned to the same parts.

[0064] Figure 1 and figure 2 As shown, the transfer molding device has an injection molding part 100, and the injection molding part 100 includes: a fixed mold 2 mounted on a fixed plate 1 and a movable mold 4 mounted on a movable plate 3, and injecting molten resin into Injection nozzle 5 in the cavity between the two moulds.

[0065] In this embodiment, the fixed disk 1 is fixed on the platform 6 , and the movable disk 3 is moved by being guided by four tie rods 7 fixed on the fixed disk 1 , and can be separated from and contacted with the fixed disk 1 .

[0066] By moving the movable platen 3, the parting surface 4a of the movable mold 4 is brought into pressure contact with the parting surface 2a of the fixed mold 2, thereby becoming a forming part of the mold (the forming part 2b of the fixed mold 2 and the movable mold 4). Th...

Abstract

A decal transferring method which, when a molded article has a pattern misalignedly transferred thereto, is capable of automatically correcting the misalignment such that the molded article has such pattern transferred thereto at a predetermined position. In the case where there is misalignment of the pattern in a molded article, the misalignment dimension and misalignment direction of the pattern (21) in the molded article (b) are detected as digital values, and a decal transfer film (20) is automatically moved by an amount corresponding to the detected misalignment dimension in a direction opposite to the detected misalignment direction so as to correct the position, whereupon the pattern (21) is transferred to the predetermined position on the transfer-molded article (b).

Description

technical field [0001] The present invention relates to a transfer molding method and a transfer molding device for sandwiching a transfer film between molds and transferring a pattern on the transfer film to a molded product simultaneously with the molding. Background technique [0002] A transfer molding device disclosed in Japanese Patent Application Publication No. 1-59095 is known. [0003] This transfer molding device is equipped with: a movable die set on a movable plate, a fixed die set on a fixed plate, an injection nozzle, a film for transfer, and a film mounted on a plate so that it can move freely in the width direction of the film for transfer. A film delivery device on the upper portion of the movable platen, a film winding device and a transfer film position detection device mounted on the lower portion of the movable platen movably in the width direction of the transfer film. [0004] Then, the transfer film is moved in the longitudinal direction while the m...
