Problems solved by technology

However, since the die-casting machine only needs a large clamping force in the last stroke of the cylinder stroke, if the cylinder with a large inner diameter is used for the entire stroke, it will waste the mold clamping time

Abstract

The invention discloses a fast die closing oil cylinder used for a high-speed die-casting machine. The fast die closing oil cylinder comprises a die closing cylinder rear cover (1), a die closing cylinder barrel (2), a die closing cylinder front cover (3), a die closing cylinder piston (4), a die closing cylinder piston rod (5), an oil supply hole (6) and an oil return hole (7), wherein the die closing cylinder piston rod (5) is internally provided with a cavity (9) used for a fast piston rod (8) to insert, the fast piston rod (8) is internally provided with a through hole (10) arranged along the axial direction, and the other end of the fast piston rod (8) sequentially penetrates through the die closing cylinder piston (4) and the die closing cylinder rear cover (1) so as to enable the through hole (10) to be communicated with a main oil path of a hydraulic system, so that the hydraulic system can push the die closing cylinder piston rod (5) to move forward by supplying oil into the cavity (9) through the through hole (10). The fast piston rod is arranged in the die closing cylinder piston rod, so that the die closing speed is improved by more than 60 percent, and meanwhile, the die opening speed is improved by increasing the diameter of the die closing cylinder piston rod.

Description

technical field [0001] The invention relates to the technical field of oil cylinders, in particular to a fast mold-closing oil cylinder for high-speed die-casting machines with fast mold-closing speed and high mold-opening efficiency. Background technique [0002] Nowadays, die-casting machines all use ordinary oil cylinders. The structure of this type of oil cylinder is as follows: figure 1 As shown, its components include mold clamping cylinder back cover 1, mold clamping cylinder barrel 2, mold clamping cylinder front cover 3, mold clamping cylinder piston 4 and mold clamping cylinder piston rod 5, and the two ends of mold clamping cylinder cylinder 2 are respectively fixed At the mold clamping cylinder rear cover 1 and the mold clamping cylinder front cover 3, the mold clamping cylinder piston 4 is arranged in the mold clamping cylinder barrel 2 and the fixed end of one end of the mold clamping cylinder piston rod 5 is arranged on the mold clamping cylinder piston 4, in ...
