The sealing power is weak. Therefore, if the pressure inside the cavity at the time of resin injection is high as in general resin injection molding (several hundreds of kg / cm 2 ), burrs are easily generated between the rubber hose 1 and the mold 9, so that the injection pressure is low. It becomes the condition setting of
It was very difficult to simultaneously injection-mold the three-way resin nipple 2 and the two-way resin nipple 3.

Corresponding to the first lower mold and the second lower mold, and a mold moving device that alternately moves the first lower mold and the second lower mold to a position where resin can be injected. Has a first upper mold and a second upper mold which are gripped by the upper bolster at a position to be held, and has a resin injection port and can be moved up and down to grip or release the first upper mold and the second upper mold. It consists of an upper bolster equipped with a clamper that

注入と同様である。When the second lower mold is moved to the position where the resin can be injected, the upper bolster is lowered to clamp the first and second upper molds and the lower mold, and at the same time, the resin is injected from the resin injection port of the upper bolster. Resin is injected into the mold of 2. At this time, since the resin is injected into one mold, the injection pressure may be low, and burr does not appear at the boundary with the rubber hose, as in the case of the first mold injection.
