Operation method of an injection molding machine

Abstract

The invention discloses an operation method of an injection molding machine, comprising: step a, the injection molding machine performs mold clamping action; step b, the injection molding machine performs high-pressure mold clamping action, and the piston of the mold opening and closing cylinder further pushes the cross thrust seat to move forward , and lock the stop template; step c, the injection assembly executes the injection action; step d, the hydraulic oil circuit of the mold opening valve in the injection molding machine controls the operation of the mold opening and closing cylinder, and drives the cross thrust seat to loosen and retreat less than the mold opening distance The preset distance n of m, and the high-pressure mold clamping state of the movable platen is maintained by the mold opening and closing cylinder and the connecting rod; step e, the injection component performs the material storage action; step f, executes the mold opening action, and demoulding, and then executes Step a. In its technical solution, a short-distance mold opening action is performed after the injection action and before the material storage action, which reduces the deformation time of each clamping part of the injection molding machine and the mold, can increase the service life, reduce vibration and noise, and reduce energy consumption. consumption.

Description

technical field [0001] The invention relates to the technical field of injection molding machine equipment, in particular to an operation method of an injection molding machine. Background technique [0002] The double toggle clamping device usually used in the existing plastic injection molding machine, refer to figure 1 As shown in , it is a mold clamping structure of injection molding machine disclosed in the document "Working Principle and Structure of Injection Molding Machine" in Baidu Library. During the mold clamping process, the piston rod of the mold opening and closing cylinder pushes the cross thrust seat to move. Then the connecting rod is pushed by the cross thrust seat to straighten the connecting rod to achieve the effect of locking the mold. At this time, the template, connecting rod, lock shaft, cross thrust seat, tie rod and other components of the injection molding machine and the mold will be deformed, and the clamping force The higher the value, the gr...

[0002] The double toggle clamping device usually used in the existing plastic injection molding machine, refer to figure 1 As shown in , it is a mold clamping structure of injection molding machine disclosed in the document "Working Principle and Structure of Injection Molding Machine" in Baidu library. During the mold clamping process, the piston rod of the mold opening and closing cylinder pushes the cross thrust seat to move. Then the connecting rod is pushed by the cross thrust seat to straighten the connecting rod to achieve the effect of locking the mold. At this time, the template, connecting rod, lock shaft, cross thrust seat, tie rod and other components of the injection molding machine and the mold will be deformed, and the clamping force The higher the value, the greater the deformation, the longer the force time, the greater the damage to the parts of the injection molding machine, and the longer the force time, the greater the waste of energy consumption, and the vibration and noise generated during the mold opening process. will be bigger
