は、型締めの精度の高いコントロールはできなかった。Conventional technology Conventionally, injection compression molding molds require a precise mold clamping mechanism using a servo motor to separate the mold clamping positions during resin injection and subsequent compression, and a general-purpose hydraulic mold clamping mechanism cannot. , it was not possible to control mold clamping with high precision.
機構でも利用することができる射出圧縮成形法を提供す
ることを目的とする。The purpose of this invention is to provide an injection compression molding method that can also be used in mechanisms.

ーティング面から除くため進退出をさせる。1 is a stationary side mold, 2 is a movable side mold, and they are Okayama (Fig. 1(a)). Next, the mold clamp is loosened, the spacer 3 is removed from the parting surface, and the mold is clamped and compressed again (Figure 1 (b)).The spacer 3 is, for example, as shown in Figure 2. , is attached to the operating unit 5 of the air cylinder, and moved forward and backward in order to interpose it on the mold parting surface or remove it from the mold parting surface.

めを行ない圧縮力を加える。Function: According to the present invention, the mold clamping position during resin injection can be determined by interposing a spacer on the mold parting surface. Then, after the resin is injected, the mold clamp is loosened to remove the spacer, and the mold is clamped until the parting surfaces of the mold come into contact to apply compressive force.

介在と除去の手段を示す断面説明図である。Effects of the Invention As described above, the present invention allows easy control of mold clamping during resin injection and the subsequent process of applying compressive force by intervening and removing spacers. The fact that a hydraulic mold clamping mechanism can also be used is sufficient, and its industrial value is extremely high. Figure 1 is a cross-sectional explanatory diagram showing the process of mold clamping and compression after resin injection in the present invention, and Figure 2 is a diagram showing the process of mold clamping and compression after resin injection in the present invention. FIG. 3 is a cross-sectional explanatory diagram showing means for intervening and removing.
