INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to in-mold surface decoration technology, and more particularly to an in-mold film cutting process. -5【Previous technology】 . ^Pursuing the high precision and high quality of plastic parts, the traditional processing technology ❹ 6 can not meet the needs of the times, so various surface decoration processes are born, the hang-up process will put the decorative film into the mold Inside, and after the mold is closed, the plastic is injected to form the plastic and the film, whereby the release surface is covered with the decorative film, and the aesthetic appearance of the finished product can be improved. The heating and forming process is such that the edges are all provided with large burrs to absorb the shrinkage amount produced by the molding and after the process, and the finished product i such as the first ❹15 edge 1a still has a large film. The burr is 1, so it must be processed by the subsequent _d cutting and finishing process to achieve the desired aesthetics of the finished product i. However, the subsequent burrs 2 cutting operations must be carried out by the person cutting device, and the lining is added again. The trouble of I is 4 1 . The increase of the time and the cost of the equipment and the productivity of the product are further improved. The finished product is 丨 _ film burr 2 and then = the cutting process is still easy to occur after the cutting process, the overall Observability and refinement result in low shape and shape of finished product 1. In addition, there is occasional flashing in the process of injection molding, which causes the finished product 1 to be unattractive. (4) 200936349 In this case, the inventor of this case is Having a detailed understanding of the development and manufacturing experience of the relevant industry 'There are products of the present invention. ^Inventive content is intended to provide an in-mold thin-cutting process ❹ 15 进行 Before the film in the mold The cut-off Ϊ' = rate reduces the cost of the subsequent burrs of the conventionally-released finished product, and the cost is achieved by the present invention. The following steps are provided: first, 'provide-mold and-shot film: two =: module Γ I second module and a module provided on the first module 2 module - film ' and (4) film is placed on the first, ghost, and then the first module and two of the mold - a cavity, and the cutter member is in conflict with the film, and then the operation of the injection machine will inject the plastic into the cavity of the mold to make the thin joint; finally, the second module is relatively Separate and take out into a special or» 〇 _ is 'the invention borrowed The cutting member is precisely cut into the inside of the mold in advance, in addition to improving the strength, time and equipment cost of the finished fabric, and improving the production efficiency. [Embodiment] The following is a list of preferred embodiments of the present invention.

Then, the film is heated and vacuum-adsorbed. Referring to the tenth and eleventh views, in the embodiment, the thin film 10 is rotated, and an external heating device 23 is moved to the corresponding hollow portion 2la. The position is heated by 10 in a manner that is at least greater than the thickness of the clamp 21, when the film 10 is After a predetermined time of heating to the medium 7 20 200936349 state, the vacuum source vacuum suction is activated, and since the cavity 16 is in a closed state, the thin 10 can be attracted and closely attached to the second module 15 The bottom surface of the cavity 16 is ❹15, and then the in-mold film 10 is cut. Referring to Figures 12 to 14, the first and second modules 13 and 15 are closed, and the mold is passed through the The hollow portion 2ia of the clamping member 21 is enclosed with the cavity 16 of the second module 15 to form a closed cavity 1〇2. At the same time, the cutter member 3G on the mold core μ extends into the cavity 1G2. And adjacent to the inner wall surface 161 of the cavity 16 of the second module 15, the blade portion 31 extends into the slot Wa' of the cavity 16 to completely cut the film 1〇; after the film 10 is cut, Next, the plastic injection operation is carried out. Referring to the fifteenth and sixteenth drawings, the injection machine 11 injects the plastic S from the injection tube 11a into the cavity 1〇2' of the mold 12 so that the plastic 8 is combined with the film. Forming and simultaneously closing the air pressure source; the plastic s injection invention is provided by the inclined end 3... , === The gear is limited to the cavity 12 of the mold 12, avoiding the occurrence of the use of flash, thereby improving the refinement and aesthetics of the finished product; and, in addition, because the blade 31 is close to the cavity 102 A side wall surface is flush with the inner wall surface of the mold 2 of the second module 15 so that the cutting precision of the thin 臈 1 可 can be improved: such as the fineness and aesthetics of the finished product. Finally, the mold opening operation, five operations The first and second modules 13 and 15 are opened, so that the burrs of the finished film 2G0 '(4) the film H) shown in the second embodiment are removed by the mold potential, so that the finished product 200 has a thin edge of 2〇1. Therefore, after two times of processing, the structure with high precision and high appearance can be obtained. No. 20 200936349: It can be used for two deaths: a cutter with a blade length equal to the film 10 can be used, so that it can be removed in the same way. Film burrs. The bee knows that the present invention directly performs the cutting operation by using the cutting edge member 30 pi 7m in the mold 12, so that the finished product 200 has no burrs around, or can be thicker than _ 1 (). cut

Therefore, we only need to apply a little force to the film of the finished product 301 to remove it, so as to obtain high precision and high appearance. Compared with the conventional product, the in-mold film cutting process of the present invention can greatly reduce or save the processing cost of the subsequent burr cutting operation of the conventional decorative film, and save a lot of manpower. , time and equipment cost and high production efficiency, and there is no jagged situation after the film around the finished product is trimmed 15, so that the finished product 200 obtained by the in-mold film cutting process of the present invention is used. It has high refinement and aesthetics, and has commercial advantages and added value. In addition, the present invention directly holds and fixes the film 1 by using the clamp 21 of the mold 12, and holds the film 10 and the heating device 23 one. Proper distance, then match the upper air hole 18 Meter, whereby the finished products 20 having a large bend angle of 200, but also enhance product accuracy and product quality. It should be noted that the cutting blade member 30 of the embodiment is assembled and coupled to the first module 13 by means of a buckle. In addition, the cutting blade member of the present invention can also be integrally formed on the first module. In addition, the cutting blade member 30 of the present invention may also be movable, that is, the person can change the cutting blade member 30 of an appropriate length depending on the thickness of the film 10, or the cutting blade member 30. The displacement can be finely adjusted by an adjustment mechanism (not shown) to change the length of the blade portion 31 to match the film of different thicknesses.
