ルディング１を取出す。The conventional manufacturing method is to first press-form a metal plate and expose the exposed portions 4aX, l-! A metal molding 4 having a portion 4b and a through hole 4c is formed. Then, as shown in FIG. 6, the metal molding 4 is placed on the cavity mold 5 in an open state so that the exposed portion 4a is in contact with the protruding portion 6. In this state, the core mold 7 is lowered and clamped, and the presser pin 8 is pressed against the round surface of the exposed part 4a of the metal molding 4 from the opposite side of the protruding part B, so that the exposed part 4a is brought into close contact with the protruding part 6. Next, foamable resin is injected into the cavity space 9 through the sprue 11 and the gate 10 to form the molding 1, and after cooling, the mold is opened and the molding 1 is taken out.

の１Ｙ４ｆｌい状態に復元し、離型が容易に行われる。The manufacturing method of the molding 1 is to form a metal molding 4 in the same manner as in the conventional method, set it in a cavity mold 5 as shown in FIG. 6, and perform injection molding by clamping the mold as shown in FIG. 4. At this time, the presser pin 12 is made of silicone rubber, and if the pin 12 is not in contact with the presser pin 12, it should be bent as shown in Fig. 7 and press the molding 4 with an appropriate pressing force. The exposed part 4a is brought into close contact with the protruding part 6, and the exposed part 4a is
It does not form unevenness, roughness, or cracks on the surface. After cooling, when the mold is opened and the molding 1 is taken out, the presser pin 12 is restored from the carved shape shown in FIG. 7 to the 1Y4fl shape shown in FIG. be exposed.
特にシリコンラバーは合成樹脂に接着しにくいので離型
しやすい。In particular, silicone rubber is difficult to adhere to synthetic resin, so it is easy to release from the mold.

起って型内に充満し、ひけが防止される。The shape and structure of the molding 1 are not limited to those shown in the drawings, as long as they can be manufactured by inserting the gold IA molding 4 into an injection mold and integrally injection molding the molding 1. In this case, the shape and structure of the metal molding 4 are not limited either, and the entire metal molding 4 may be exposed. As in the embodiment, the structure in which the through hole 4c is formed with a part of the buried portion 41 is provided with rigidity, and the through hole 4
c, and attach the resin part 2 in an anchor shape on both sides of the buried part 41).
is formed, peeling +q+1. , there is no risk of it falling off. When the through hole 4c is provided, sink marks are generally likely to occur on the surface of the hole due to injection molding, but when foamable synthetic resin is used as the injection resin, sink marks are less likely to occur, especially when using reactive molding. Injection Mo
If molding is performed by molding, the occurrence of sink marks on the dish can be reduced. In reactive injection molding, a reaction occurs in the mold and foams. In the case of foamed urethane, the reaction between inocyanate and polyol causes foam to fill the mold, preventing sink marks. Ru.

。As described above, according to the present invention, a metal molding is installed in an injection mold so that at least a part of the metal molding comes into contact with the mold surface, and the contact part is inserted into the injection molding part from the opposite side. (Since the injection molding is performed after pressing the metal molding with a suitable pressure, the metal molding is pressed with a moderate pressure to make it adhere tightly. This prevents the occurrence of irregularities, cracks, etc. on the outer surface, and gives an excellent appearance. It is possible to manufacture a molding having a molding structure, and the molding can be easily released.
