Background technology
Existing injection molding of rubber vulcanizer generally all disposes servo-control system, control effectively by the executive component of servo-control system to vulcanizer, make the whole hydraulic system of vulcanizer remain on optimum state, thereby reduce the energy consumption of vulcanizer and improve its operating efficiency.But owing in control procedure, be difficult to effectively monitor pressure and the changes in flow rate of hydraulic system in real time and in time feed back to servomotor, thereby intelligent degree is lower, the accuracy of control is relatively poor.
The utility model content
Technical problem to be solved in the utility model is for above-mentioned prior art present situation, and the servo-control system that a kind of intelligent degree is higher, control comparatively accurate injection molding of rubber vulcanizer is provided.
The utility model solves the problems of the technologies described above the technical scheme that adopts: the servo-control system of this injection molding of rubber vulcanizer, include a certain amount of pump and be serially connected in constant displacement pump and the vulcanizer executive component between pipeline road on overflow valve, it is characterized in that: described constant displacement pump links to each other with a servomotor, the input of one rotary encoder is connected on the described servomotor, the output of this rotary encoder is connected on the servo controller, the input of one pressure sensor is connected on the described pipeline road, and the output of this pressure sensor is connected on the described servo controller.
Preferably, the input of described pressure sensor is connected on the pipeline road between described constant displacement pump and the overflow valve.Like this, pressure sensor can directly record the hydraulic system pressure on the pipeline road between constant displacement pump and the overflow valve, and and then adjusts more accurately the pressure of hydraulic system by servomotor.
Further preferred, described servomotor is permanent magnet synchronous servo motor.Because permanent magnet synchronous servo motor has response soon, the advantage that the linearity is good, thereby behind the employing permanent magnet synchronous servo motor, can further improve Product Precision and the production efficiency of vulcanizer, in addition, permanent magnet synchronous servo motor also can freely be controlled to the scope of high pressure, high speed from low pressure, low speed, thereby enlarges the scope of application of product, to satisfy better user's demand.
