Description of the invention: ‘[Technical field to which the invention pertains] In particular, the present invention relates to an injection molded article. [Prior Art] Insert molding refers to the injection of plastics into the mold after the preparation of different materials, such as metal or inorganic solids, molten plastic and different materials. The insert is bonded and cured to form a molding method for the integrated product. The formation of funeral parts can be made into complex and intricate products by using the characteristics of (4) and the flexibility and heat resistance of the different material inserts. The method of forming the parts can save the subsequent assembly and complicated operations, which can greatly improve the production efficiency. At the same time, the processing cost can be saved because the processing steps such as coating and mechanical fixing are omitted. For example, post-molding is widely used in electronic components, electrical components, automotive parts and other fields, and has become a common molding method. However, when the "melting", the high-pressure plastic produces a great injection pressure on the dissimilar materials, and the pressure between the molds of the different material materials is extremely great. In addition, due to the molten plastic, its temperature production is generally about 300 degrees Celsius, such a high temperature will inevitably cause thermal expansion of the different material rear member, thereby increasing the difference between the different material insert and the mold core. Thus, when the mold is released, the friction between the different material member and the mold core is greatly generated, so that the foreign material is left on the mold core, so that the different material insert is separated from the plastic. Referring to Figure 1, the article 10 includes a conventional insert molding 10 which is shown as a material member 12 and a plastic member 14. The different material embedding 200827150 includes a main body portion 122 and a bent portion 124, and the bent portion 124 is disposed at a periphery of the main body portion 12 2 $ with #-XJ-w. The different material insert 12 and the .4 are formed into a shape by the insert method: the body is made up of: = 夫 ” _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The frictional force of the f-fold portions 124 and 〜Bt causes the different material insert to remain in the --, and the different material insert is separated from the plastic. [Invention] In view of the above situation, it is necessary to provide _ Kind of insert molding products that can be separated from the plastic parts of the Lushan. U shell and a molded part, the insert molding material insert. The different material insert includes a main body; The dissimilar portion is extended by the main body portion. The different material is inside the rubber member. The armor member is covered by the plastic part, and the insert molding product is different from the plastic material. The splicing portion is wrapped in the plastic member. Thus, the damming portion of the member directly rubs the friction between the insert insert material forming the insert molding and the mold, thereby avoiding == different The different material insert is separated from the plastic piece. /, when opening the opening [Embodiment] Please refer to Fig. 2 and Fig. 3, which shows the molded piece of the funeral piece. 20, the material molded article 2Q f R embodiment U and a first - plastic member 24. The first different material includes an insert insert body portion 222 and a - first embedded portion 224, the second department - the first The first embedded portion 224 is disposed on the periphery of the first body portion 222. The first plastic member 24 defines a first slot. 242, the shape and size of the first slot 242 is equivalent to the first embedded portion 224, and the first embedded portion 224 is received in the first slot 242. The first slot 242 is the first slot 242 A plastic member 24 is divided into a first portion 244 that is in contact with a mold core (not shown) that forms the insert molded article 20 and a second portion 246 that is opposite the first portion 244. The first portion 244 has a first portion a surface 2442 and a second surface 2444, the first surface 2442 is in contact with the mold of the insert molding 20, and the second surface 2444 is disposed opposite the first surface 2442, the first surface 2442 and The minimum distance D between the second surfaces 2444 is 0.3 mm. The material of the first different material insert 22 is generally selected from metal or inorganic solids. The material of the plastic member 24 is generally selected from one or more of polyvinyl chloride, polyethylene terephthalate, acrylonitrile-styrene-butadiene copolymer, and phenolic resin. The first embedded portion 224 may extend from any portion of the first body portion 222 as needed. The minimum distance D between the first surface 2442 and the second surface 2442 is not limited to 0.3 mm, and the distance D should be The plastic between the first surface 2442 and the second surface 2442 is ensured to be fully injected without any lack of glue, generally not less than 0.3 mm. Referring to Figures 4 and 5, the second preferred embodiment of the present invention is shown. The insert molded article 30 includes a second different material insert 32 and a second plastic member 34. The second material insert 32 includes a second body portion 322 , a second insert portion 324 , and a flange 326 . The second insert portion 324 extends from the second body portion 322 . The second embedding portion 8 200827150 324 is disposed on the periphery of the second main body portion 322, and the flange is like to extend from the end of the second embedding crucible 324. The flange is rigidly arranged perpendicular to the second embedding portion. . The flange 326 extends beyond the second insert portion to a length of 1 mm. The second plastic member 34 defines a second slot, such as the shape and size of the second slot 342, and the second female portion 324 and the flange, the second embedded portion 324 and the A flange 326 is received within the second slot 342. The second (four) 342 divides the second plastic (four) into a "part" portion 344 that is adjacent to the mold core (not shown) that forms the molded article 30, and a second portion that is opposite to the first portion 344. tear. The first portion 344 has a first surface and a second surface. The first surface 3442 is formed with a mold core for molding the insert molded article 2, and the first surface is disposed opposite to the second surface 3442. The minimum distance F between the first surface 3442 and the second surface 3444 is 〇·3 millimeters. The position of the flange 326 is not limited to being formed at right angles to the second recessed portion as the second recessed portion, and may be any angle not on the same straight line, preferably
