Hydraulic die locking device for die assembly of die casting machine

Abstract

The invention provides a hydraulic die locking device for die assembly of a die casting machine and relates to the technical field of die casting machines. The hydraulic die locking device is characterized by comprising a die assembly cylinder, a front cover of the die assembly cylinder, a rear cover of the die assembly cylinder, a die assembly piston, a die assembly piston rod, a die assembly piston rod guide sleeve and a die assembly guide sleeve gland, wherein the front cover of the die assembly cylinder is fixedly arranged at the front end side of the die assembly cylinder; the rear cover of the die assembly cylinder is fixedly arranged at the rear end side of the die assembly cylinder; the die assembly piston is arranged in the die assembly cylinder; one end of the die assembly piston rod is connected with the die assembly piston, and the other end of the die assembly piston rod extends to the exterior of the front end of the die assembly cylinder; the die assembly piston rod guide sleeve sleeves the die assembly piston rod and is fixedly arranged at the front end of the die assembly cylinder; the die assembly guide sleeve gland is fixedly arranged at the front end of the die assembly cylinder and positioned at the outer side of the die assembly piston rod guide sleeve. The system is high in die assembly speed and die sinking speed, good in sealing effect, low in pressure relief possibility and easy to assemble; a hydraulic system for die assembly is relatively stable and relatively high in die locking force.

Description

Technical field: [0001] The invention relates to the technical field of die-casting machines, in particular to a hydraulic die-clamping device for die-casting machines. Background technique: [0002] Die-casting machine mold clamping system is an important part that determines the performance of die-casting products. At present, traditional die-casting machines basically use barrel-type manual clamping system. This system requires extremely high machining accuracy of mold clamping cylinder and mold clamping piston rod. Workers are not suitable for assembly, especially when the mold clamping cylinder and the mold clamping piston rod are installed with different cores, the seal of the mold clamping cylinder and the mold clamping piston rod is not good, it is easy to leak and scratch the cylinder wall, and it is easy to lose the clamping force during work, resulting in The molding pressure is unstable.
