工金属板１５と合成樹脂１６とが一体化される。(Background Art) Conventionally, in order to integrally mold metal and synthetic resin, an apparatus as shown in FIG. 7 has been used. In the figure, 1 is a plate portion of a sheet metal mold, 2 is a punch guide, 3 is a spring, 4 is a stripper plate, 5 is a punch, and 6 is a die. Here, a metal plate (sheet metal) 15 to be processed is placed on the die 6, and the metal plate 15 to be processed is struck from above with the punch 5 to make a hole in the metal plate. Next, using an apparatus as shown in FIG. 8, a synthetic resin is poured into the holes provided in the metal plate 15 to be processed and integrally formed. In this case, the movable mold part 9, the spacer block 10, the upper ejector plate 1
1. Move the lower ejector plate 12 and the movable mounting plate 13 to open the mold, place the workpiece sheet metal 15 processed in the previous process, then close the opened part by moving as described above, The synthetic resin 16 is poured into the holes and mold parts 8 and 9 formed in the metal plate 15 to be processed, and is solidified to integrate the metal plate 15 and the synthetic resin 16 into one body.
上述のごとき従来の方法では次のごとき欠点を

に制約がある為、多くの樹脂固定部を配置でき
ない。そのため接着強度が弱くなるものであ
る。 That is, (a) the adhesive strength between the metal plate 15 to be processed and the synthetic resin 16 is low. This is because there are restrictions on the size of the holes in the metal plate to be processed, so many resin fixing parts cannot be arranged. Therefore, the adhesive strength becomes weak.
(ロ) 合成樹脂のムダが多い。これは金属板との固
定の為に使用する樹脂を多く必要とするためで

ストの増加となるためである。(c) Increase in mold costs. This is because the structure of the mold becomes complicated due to the fixation with the metal plate, resulting in an increase in mold cost.
(ニ) 被加工金属板の他面に影響を与えず一面のみ
に合成樹脂を強い接着強度で形成することがで
きない。(d) It is not possible to form a synthetic resin with strong adhesive strength on only one surface of the metal plate to be processed without affecting the other surfaces.
