連結されている。 The link mechanism 4 has a joint portion 4a in the center and is configured to be bendable, the base end side 4b is supported by the fixed portion 5, and the free end side 4c is connected to the base plate 3a of the pressurizing means 3.
上記の構成において、先ず、第１図に示される
ように、リンク機構４を折曲した状態で、固定側
金型１及び非固定側金型２の清掃等の準備作業を
行う。 In the above configuration, first, as shown in FIG. 1, preparatory work such as cleaning of the fixed side mold 1 and the non-fixed side mold 2 is performed with the link mechanism 4 in a bent state.
次に、第２図に示されるように、リンク機構４

ク機構４の最大ストロークは非固定側金型２が固
定側金型１の近傍まで対向接近するように設定さ
れている。 In addition, in Fig. 2, fixed side mold 1 and non-fixed side mold 2 are shown.
Although the opposing distance is exaggerated in the illustration, the maximum stroke of the link mechanism 4 is set such that the non-fixed mold 2 approaches the fixed mold 1 in opposition.
さらに、第３図に示されるように、加圧口３ｃ
から図示外のポンプを介して流体Ｆを供給する。
これにより、ダイヤフラム３ｂが膨出し、非固定
側金型２が固定側金型１を押圧する。 Furthermore, as shown in FIG. 3, the pressurizing port 3c
Fluid F is supplied from the pump via a pump not shown.
As a result, the diaphragm 3b expands, and the non-fixed mold 2 presses the fixed mold 1.
この状態で、スプルー２２から溶融した樹脂Ａ
が高圧力で充填される。 In this state, the molten resin A from the sprue 22
is filled with high pressure.
この時、非固定側金型２は、流体Ｆによる均一
