Description
Technical field
The present invention relates to die casting machine technical field, especially relating to a kind of adjustment servicing unit for adjusting die-casting machine position.
Background technology
The Clamping System of tradition horizontal plunger die casting machine all contains back seat plate [tailgate], moving platen [middle template] and solid plate [front template].The cover half of production mould is fixed on solid plate, dynamic model is fixed on moving platen.According to the size of production mould, usually to adjust the initial position of back seat plate and moving platen, thus suitable adjustment is carried out to clamp force, thus prevent the excessive and too small situation of clamp force.The adjustment of the initial position to back seat plate and moving platen like this adjusts referred to as template.The template adjustment of existing horizontal plunger die casting machine, mainly by being arranged on low-power motor on back seat plate and realizing with the work of the gear transmission structure of this low-power motor auxiliary work.Transmission horizontal plunger die casting machine is when template adjusts, low-power motor driven gear transmission mechanism works, the adjustment nut that gear drive transmits torque to four driving screw ends makes adjusting nut rotate, adjusting nut engages with to screw flight, and the rotation of adjusting nut just makes driving screw appearance stressed.When adjustment nut turns clockwise, adjustment nut moves towards solid plate, thus promotion back seat plate moves to solid plate.When adjustment nut is rotated counterclockwise, adjustment nut moves away from solid plate, thus drives back seat plate away from solid plate.The mobile meeting of back seat plate drives moving platen to do simultaneously and moves in the same way, thus the distance that can adjust between moving platen and solid plate, the situation of the distance between moving platen and solid plate and die casting is adapted, thus controls the elastic deformation amount of driving screw, reach the object controlling clamp force.The template adjustment mode Problems existing of existing traditional horizontal plunger die casting machine is: the live load for the low-power motor of template adjustment is large, when this template adjustment mode is used for large-scale die-casting machine, damaging easily appears in described low-power motor, and the efforts efficiency of template adjust structure and poor reliability, working service cost are high.
Summary of the invention
Main inventive object of the present invention is to provide a kind of live load of the low-power motor that can reduce in template adjust structure, thus is conducive to improving the operating efficiency of template adjust structure and reliability and reduces the die-casting machine adjustment servicing unit of the working service cost of template adjust structure.
