OBJECTS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a molding apparatus, and more particularly to a molding apparatus for in-mold decoration. [Prior Art] When forming a plastic product by an injection molding process, it is often necessary to draw a decorative text or pattern on the plastic product. A commonly used method for drawing characters or patterns is a secondary processing method, that is, after injection molding of a plastic product, printing, spraying, and the like are performed on the already formed plastic product, thereby finally forming a plastic product having characters or patterns. The process of the secondary processing method is cumbersome and the production cycle is also long. The in-mold decoration process can shorten the production cycle and increase production efficiency. Fig. 2 and Fig. 2 show a schematic view of a molding apparatus used in an in-mold decoration technique in the prior art. The molding apparatus includes a mold having a cavity and a film 30'. The mold 20 includes a male mold 22 and a female mold 24. The film 30 is disposed between the male mold 22 and the female mold 24, and is attached to the inner wall of the cavity 10. The two ends of the thin film 3 are pressed against the joint between the male mold 22 and the female mold μ. Parting surface. The substrate 30 of the film 30 is provided with a transfer layer 32 of a throwing text or pattern. After molding, the plastic is injected into the cavity 10 between the male mold 22 and the female mold 24, and after the cooling is opened, the transfer layer 32 and the substrate of the film 3 are separated from each other and attached to a molded part 4 From the above, the injection molding can be used to form a plastic article with V characters or patterns. • Since the film 3G is bent at the intersection of the inner wall of the cavity 1G and the parting surface, it is easy to cause the transfer layer 32 not to completely conform to the edge surface of the molding. At this time, the molded article 4 is used. The words or patterns formed on the paper will create a deficiency, which will affect the integrity and yield of the product. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide an in-mold decorative molding device that can form a complete text or pattern on the edge of a molded article. + A molding device for in-mold decoration, comprising a mold and a decorative thin enamel. The mold includes a male mold and a female mold. The master mold is provided with a cavity, the film. The split is located on the inner wall of the cavity and extends outside the cavity. The portion of the film outside the cavity is pressed against the parting surface between the male and female molds. The depth of the cavity is greater than the height of the molded part to be formed. A molding device for in-mold decoration, comprising a male mold, a female mold and a decorative film. The master mold is provided with a cavity which is disposed on the inner wall of the cavity and extends outside the cavity to be pressed and fixed. The male mold is provided with a stepped portion. The mating portion includes a first mating portion and a second mating portion. The first mating portion and the second mating portion respectively extend into the cavity for forming. The inner surface and end edge of the molded part to be formed. The cavity of the above-mentioned in-mold molding device has a cavity depth higher than the height of the molded part. The first fitting portion of the surface and the end edge is formed on the male mold for projecting into the cavity to form the inner surface of the molded part. The second mating portion, so that the film does not bend at the end edge of the molded part, the film can be prevented from being bent in the cavity, and the in-mold decorative text or pattern is missing, and the integrity of the molded part is ensured. With yield. [Embodiment] Referring to Figures 3 and 4 together, a preferred embodiment of the in-mold molding apparatus of the present invention comprises a mold 50 and a film 60. © The mold 50 includes a male mold 52 and a female mold 54 which defines a cavity 56 having a depth greater than the height of the molded part to be formed. The male mold 52 is provided with a fitting portion 57 corresponding to the cavity 56 of the female mold 54. The mating portion 57 is substantially stepped and includes a first mating portion 572 corresponding to the inner surface of the forming member and a second mating portion 574 corresponding to the end edge of the opening of the forming member. The film 60 is located on the inner wall of the cavity 56 of the female mold 54 and extends between the male mold 52 outside the cavity 56 and the female mold 54. The film 60 is disposed on one side of the male mold 52. A transfer layer 62 corresponding to the text or pattern to be formed is required. When the mold is closed, the fitting portion 57 of the male mold 52 projects into the cavity 56 of the female mold 54. A portion of the film 60 that is located within the cavity 56 is attached to the inner wall of the cavity 56. The portion of the film 60 outside the cavity 56 is pressed against the parting surface between the male and female molds 52, 54. Plastic is injected into the cavity 56, and the cavity 56 is filled to form a molded piece 70. An end edge of the opening of the molded piece 70 is formed at the second fitting portion 574 200924943 of the male mold 52. At the time of demolding, the male and female molds 52, 54 are separated, and the transfer layer a is separated from the film 60 and left on the molded article 70 to form a desired form. Compared with the prior art, the depth of the cavity 56 of the above molding device is higher than the height of the molding member 70, and the end edge of the molding member 70 and the female mold 54 2 i face 58 are called for a preview. The film is not bent at the edge of the molded part, so that the film 6 is prevented from being bent on the outer surface of the end edge of the molded piece, so that the outer surface of the end edge of the molded piece 7G is out. The absence of decorative text or patterns guarantees the finished product and yield of the molded part 7().
