[Technical field to which the invention belongs] The present invention relates to a method and mold for in-mold decoration, and in particular, to a method for positioning a decorative material in a mold cavity and a mold bean used in the method. [Prior art], 〃

Please refer to the first picture, the in-mold decoration is the process of completing the decoration during the injection molding process of the plastic parts, that is, regardless of the color and pattern, it is completed with the B guard in the injection molding, and not necessary for injection molding. Print after the process. Decorated in Ernest! During the manufacturing process, a pre-shaped decorative material having a three-dimensional shape such as a film f 'is placed in the mold groove of the concave mold 12 of the mold 10, so that the fish filling = 3 0 and the groove of the mold groove 12 are formed. The surface 3 is matched, and then the convex mold i 4 and the concave mold 12 are closed to form a cavity 16, and the products such as plastic are injected into the cavity 16 to make the decorative material 30 and the filler. Combined to form an in-mold decoration ^. The conventional parting line 18 of the mold 10 used for in-mold decoration is broken by ^ ^ ', that is, the depth of the groove of the concave mold 12 is the same as the height of the decorative material 30, = the parting line 18 is perpendicular to the closed mold Direction 2. Applying the mold 10 for in-mold filling process ′ Put the decoration material 30 into the mold groove of the concave mold 12 of the mold 10 4 The decoration material 30 cannot ensure completeness with the surface 13 of the mold groove of the concave mold 12

* Mouth misalignment occurs, for example, the side of the decorative material 30 is higher than the mold groove. At this time, it is necessary to use a positioning device other than the molding machine to move the decorative material 30 to the correct position so that the decorative material 30 does not completely match the surface 13 of the mold groove. If the positioning process is omitted, the decoration material of the device before the mold is closed may be easily dropped from the mold groove of the concave mold 12. After the mold is closed, the decoration material 30 cannot be fixed in the cavity 16 and injected into plastic. When waiting for the filling, the decorative material 30 is located at a predetermined position of the plastic product, which affects the quality and

200534988 bits, missing white and other defects. If the positioning equipment is added and the cost is increased, a cost saving and time saving need to be provided. It is necessary to use the bit method and the materials used in this method. The cost reduction method, which provides a package including the matching of the package, the surface, the mold, and the close matching of the decorative material, the invention can be used to install the convex mold of the mold, the copy; 15. Description of the invention (2) The finished product has a burr to increase the molding machine. In view of this, 30 is determined in the cavity. [Summary of the invention] The purpose of the present invention is to locate the mold of the purpose of the present invention, which has an external surface in order to achieve the positioning in the cavity; In the mold, the concave mold is provided with an outer surface of the mold groove decoration material, so that the main surface portion of the outer surface and the edge portion of the mold groove are opposed to each other during the process. It is used for in-mold decoration, which includes: an integral part and a positioning part to provide a cost-saving and time-saving feature to provide a mold section. The invention includes the following molds, the main part of which includes an edge; the surface of the groove is formed The mold cavity is closed, and the order is made for its purpose. The decorative material can be concave on the convex mold. The positioning time of the decorative material in the cavity is the time when the decorative material is in the cavity. . Invented to provide a step ox sand · Tan 禋 clothing materials in the step "· Provide a dream clothing decoration materials, including · a convex mold, the convex 槎 μ and positioning part ·, | |, a concave mold, this part 'The surface of the mold slot: The decorative material is placed in the mold slot of the female mold & •' The male mold is closed with the female mold, " section, the positioning portion is inserted into the mold slot = the bit portion is inserted into the edge of the mold slot ^ The invention is in accordance with the surface of the mold groove. The invention provides a mold cavity for positioning in the mold, which includes: two decoration materials are provided with a mold core in the mold cavity, the mold core includes a mold groove on the main concave mold, It includes on page 6 V. Description of the invention (3) An edge portion; the edge portion that enters the mold groove cooperates to form a cavity, and the positioning portion ★ I 紧密 closely cooperates with it after the mold is closed in the mold closing direction. , The main part and the surface of the mold μ fruit groove and the outer surface of the decorative material can be inserted into the cavity to match the self-known decorative material in the mold cavity; mold 'the decorative material of the present invention in the cavity; bit; =; Methods :: No need to increase equipment outside the molding machine to save costs, use: "" Position without positioning step, the time section. Cost-utilization pull tool [Performance application method] The decorative material of the present invention completes the positioning of the decorative material in the cavity of the mold at the same time. 楛 _ 向 + _ y is tied to the closed branch. Refer to the second figure Ϊ: It includes the following steps: Decoration material_ is used for product decoration material 30, this equipment 2, § The outer surface is used to contact the external environment, Bao Er:: The surface is in contact with the material forming the product and tightly combined; Hai = 3 Er may: r is tailored After molding, it has a satin-shaped film with a decorative pattern, and a decorative picture can be printed thereon. Provide a positioning method of the decorative material 30 used in the present invention in the mold cavity = mold 20, which includes a concave mold 22 and a convex Die 24, the die 22 is provided with a die groove. The mold groove 23 includes a bottom surface 230 and a side surface 231, and the bottom surface 230 and the side surface 231 are connected to form a surface of the mold groove. The height H of the side surface 231 of the mold groove 23 is greater than the height h of the decorative material 30. The part of the mold groove 23 deeper than the decorative material 30 is the edge part 232, and the edge. The surface of the part 2 32 is smooth, and the mold groove 23 200534988 V. Description of the invention (4) Except the edge part 2 3 2 Out of the surface, the outer surface of Zhexian matches. Therefore, when the part of the decorative surface is matched with the surface of the packaging material 30, the edge portion: 2 3 ° /: in the mold groove 23, and ^ > 1-6D 6 2 5 includes a main part price 251 and a positioning part 252, the main part Qiu Yu 9 ιι, the royal body hurt. ^ ^ ^ 4 The surface of the main part 25ϊ is formed into a product ί =; f, the positioning part The surface of part 252 is smooth.
