Abstract
The invention discloses a system and method for measuring the kinematic characteristics of a double toggle mold clamping mechanism of an injection molding machine, comprising a base, a double toggle mold clamping mechanism, a push-fit power device, an acceleration sensor, a speed sensor, a displacement sensor, an inclination sensor, a force sensor, and a force sensor. Sensor, measurement and control system, clamping cylinder, rear template, dynamic template, static template and double toggle transmission mechanism; rear template, dynamic template and static template are arranged in sequence, and the piston rod of the clamping cylinder is respectively connected to the rear template through the double toggle transmission mechanism. It is connected with the moving template, and the push-fit power device is connected with the static template; the acceleration sensor, speed sensor, displacement sensor and inclination sensor are connected with the double toggle transmission mechanism, the force sensor is arranged between the moving template and the static template, and the measurement and control system is respectively connected with the acceleration Sensor, Velocity Sensor, Displacement Sensor, Inclination Sensor, and Force Sensor Connections. It can quickly measure the motion characteristics of the double toggle clamping mechanism of the injection molding machine under different working conditions, with high measurement accuracy and simple operation.
Description
technical field [0001] The invention relates to the technical field of mechanism measurement, in particular to a measurement system and method for the kinematic characteristics of a double toggle mold clamping mechanism of an injection molding machine. Background technique [0002] After decades of development, more than 40 types of mold clamping mechanisms have been derived. Toggle type, full hydraulic direct pressure type, tie rodless type and two-platen type are the mainstream in the international market. At present, the general injection molding machine mold clamping mechanism is widely used in the market as a hydraulic type mold clamping mechanism, that is, a five-point mechanical hinge (toggle lever ) mold clamping mechanism, which makes full use of the stroke, speed and force amplification characteristics and self-locking characteristics of the toggle link to achieve stable and reliable mold opening and closing, fast mold closing speed and low energy consumption. It i...
