PURPOSE:To prevent a resin material from leakage in the mold clamping and breaking, by constituting that an injection molding machine can synchlonize to move with the movement of clamping and breaking of a central mold while the injection molding machine is being pressed to an inlet of a resin. CONSTITUTION:An injection device 40 moves monolithically with an interlayer 14 while its injection outlet 40a is being pressed to a resin inlet 38a of the interlayer 14. A cylinder 43 for moving the injection device being set on a slide base 42 can synchronize with a cylinder 24 for moving the interlayer and each rod 43a and 24a can thereby go forward and backward in a same speed and a same stroke. Moreover, an oil pressure driving the rod 43a backward is always acted on an acting room for driving the rod 43a backward among the acting rooms being divided by a plunger in the cylinder 43. The injection device 40 is driven to the side of the interlayer 14 as a whole and the injection outlet 40a is pressed to the resin inlet 38a of the interlayer 14. A tightly contacted and connected state is thereby kept. |
