したことを特徴とするブースタラム式型締装置。[Scope of Claim for Utility Model Registration] A movable platen slidably fitted into the main cylinder chamber so as to partition the main cylinder chamber into a mold-clamping cylinder chamber and a mold-opening cylinder chamber is brought close to the fixed platen.
A booster ram cylinder chamber is formed in the main ram for separating the ram, and the booster ram is slidably inserted into the booster ram cylinder chamber, and is provided in communication with the mold clamping cylinder chamber of the main cylinder chamber. A pre-filled valve that controls communication between the mold clamping cylinder chamber and the external oil tank is slidably fitted into the valve cylinder chamber, and the prefill valve is slidably fitted in the valve cylinder chamber to control communication between the mold clamping cylinder chamber and the external oil tank. In the booster ram type mold clamping device, the opening operation of the fill valve is performed by introducing pressure oil into a drive cylinder chamber formed between the pre-fill valve and the inner wall of the valve cylinder, wherein the drive cylinder chamber is connected to an oil passage communicating the clamping cylinder chamber and an external oil tank via a predetermined valve means, and the pressure in the direction of cutting off communication between the clamping cylinder chamber and the external oil tank is A booster ram type mold clamping device, characterized in that the drive cylinder chamber can be brought into communication with the oil passage when the fill valve is closed.
