Description of the Invention: [Technical Field of the Invention] The present invention relates to a mold for in-mold transfer. [Prior Art] In order to know the internal molding process, M堇 relies on the female mold side to draw the box film at room temperature and adsorb the positioning of the tank film in the mold cavity. Therefore, the deep-moving fork is limited to the n-film base layer itself at room temperature. Tensile limit in state: = The film itself may be damaged when it is stretched beyond its natural (four) 2 ()% or when the die cavity design has a small angle (especially the acute angle 2 due to the vacuum generated by the vacuum and fl Restriction of film base reheat deformation 1 film is not easy to completely form with the cavity ^ ΐ::上:: the lack of technology 'the industry has appeared on the box film to reveal a kind of foil port before the mold clamping, the heating device The heating device is sent to the house independently of the splicing device, and then heated and then removed by the conveying device. Therefore, the conventional technology not only needs to use the conveying device, but also causes the entire process to increase the entire process time. There is a process of deep drawing depth and small angle heating, such as an independent heating device for heating by a conventional technique, when heating is required, another heating film is required between the male and female molds, and the heating device is between the male and female molds. Bulky and complex design of the heating apparatus which apparatus structure, high cost, low-efficiency, and this structure has been deleted art limits. SUMMARY OF THE INVENTION

Referring to FIG. 5, before the mold clamping, the film feeding device 1 〇 passes through the transfer of the transfer wheel 13 and the guiding of the guide wheel 15, and the foil film 100 is oriented in the direction. The foil film 100 is applied to the surface of the master mold 30, and the foil film 1 is pressed onto the surface of the sigma mold 30, and simultaneously With the sealing ring 33, a first airtight space is formed between the foil diaphragm 100 and the cavity 31. The evacuation device draws a portion of the air in the first airtight space through the phasing vent 32, and sucks a portion of the foil film 1 into the cavity 31. Referring to FIG. 6, when the mold is closed, the press-fit frames 4 () are respectively received in the corresponding receiving grooves 25 of the male mold 20 and pressed against the sealing ring 27' of the male mold 2 to make the foil film 1〇. A second airtight space is formed between the crucible and the male mold 2〇. At this time, the exhaust grooves 23 communicate with the second airtight space. The pressure valve 80 is closed and a pressure relief threshold is set for the pressure relief valve 8〇. The heat medium source 90 transmits a certain pressure to the medium passages 29 through the pipeline 91. The heat medium (hot air in this embodiment) is heated by the hot air to move the column 70 to the side of the master mold 30. Exposing the opening of the medium passages μ=291, hot air is blown to the diaphragm (10) through the medium passages 29 (as shown in FIG. 4), and the base layer of the diaphragm 1 is softened and The side of the female mold 3 is evacuated through the exhaust grooves 32 and transmitted through the male mold 2; the common effect of the hot air heating and pressurization of the owner of the ibu tongs 29 is completely attached to the female mold 3 () The inner wall of the cavity 31. The source of the source 90 V is incapable of being disturbed. The rods 7 are reversely moved by the restoring force of the corresponding spring 79 to close the corresponding medium passage 29.

Then release the (4) frame 4〇, followed by ~;:: clear... _(10) is located in the previous molding 2 = the film is transferred between the parent molds, and the base layer in the lower-forming cycle is started from the public In the technical solution, after the mold is closed, the vacuum is added to the vacuum of the male mold, and the blow of the male mold 2 is doubled. The stretch length of the (4) 100 itself is extended, and the enamel film 100 can be reached. Even in the case of the mold cavity 30 of the mold 30 and the large ice degree, it can be combined with the mold hole 31; For example, when the master mold 30, the younger face A2, and the third surface 八 3 200842018 have a dimensional relationship of + + 2008, the length of the surface A1 of the younger brother is 以, and the length of the second surface 八 2 is u, The length of the two surfaces A3 is a3, and the effect of the perfect bonding of the mold hole 31 of the foil film 〇〇 。 3 is also achieved. As another embodiment of the present invention, the switching means of the medium passages may also be valves that are open to each medium passage 29 and automatically closed. In addition, the medium source 1" may also be: liquid, (such as water) 'the male mold 2' correspondingly set the passage for discharging the liquid medium.
