The actions of various types of hydraulic actuators μ 15圯 are generally post-molding, squeezing (four) feed rotation, (iv) cooling, squeezing cylinder reset, mold opening, and ejection of finished products.此In this-known system, the motor 1〇 is operated at a fixed speed after starting, so that the liquid view 11 provides i] constant flow and pressure oil pressure for various types of hydraulic actuators. 14,15,16 In the entire injection molding process, the required hydraulic pressure and flow rate are irrelevant amount of money and pressure pressure for the face (four) cut to meet all types of hydraulic actuation @ _. In particular, in order to meet the maximum hydraulic requirements of the above-mentioned liquid-hull actuators, the motor slaves are highly accommodating, and the liquid ship U姊 provides high-flow and surface-forced oil to the hydraulic actuators. _, _, under the demand of some reduction and strength, such high pressure will be a great source of this, and shorten the service life of electric motors and oil chestnuts. [New content] The problem is to solve the problem that the provincial oil control system cannot provide hydraulic oil suitable for flow and pressure according to the requirements of the hydraulic actuators of the injection machine. The main technical means for solving the above problems includes: a drive control device comprising at least one frequency converter and at least one controller; 3 M417250 - motor unit 'connected to the drive control woven, including at least i service motor, and connection a rotation sensing element of the shaft of the servo motor; a hydraulic pump coupled to the motor unit; an accumulator connecting the hydraulic pump and an oil passage unit of the injection machine; and a pressure switch having an upper and lower limit adjustment function, Connecting the accumulator; the items to be executed include: the controller stores the motor rotation speed required for each hydraulic actuator of the injection machine to operate at each stage; the rotary feeling piece _ the motor of the riding Difficult, (10) the controller; x worker the controller compares the measured value with the specified value, and generates a command signal to control the inverter; 7 the inverter is determined according to the _ age service (10), the rate of the ship riding, according to To change the speed of the servo motor (4), the surface of the oil pressure is output to the dragon to store; the injection machine performs the injection and preservation operation to provide the flow or flow compensation required for the operation. Supplying hydraulic hybrid stabilizing action of f. The functions of this creation include: Using the feedback control and frequency conversion principle, the servo motor achieves high stability, high response, and high precision speed control. The accumulator is used to store and maintain the stable preset movement, and when the injection machine performs the combined action of injection molding and pressure holding, the flow or flow compensation required for the operation is provided by the storage, and the composite action is required. Stable hydraulic pressure. 4 M417250 can adjust the speed of the motor according to the hydraulic and flow demand of each hydraulic actuator in the injection molding operation, so that the liquid chamber can provide the secret oil of no force and flow to meet the action of each stage of the injection machine. need. The servo motor has the best scale, reducing energy secrets and extending the life of the machine. [Embodiment] As shown in the second figure and the third figure, the energy-saving driving device for the pressure storage type of the injection machine of the present invention mainly comprises: - a drive control device 20, - a motor unit 4 〇, a hydraulic spring 5 〇, an accumulator 6〇, and pressure switch 70. The drive control device 20 includes a frequency converter 21 and a controller 22, and has a function of feedback control. The hydraulic oil flows of the hydraulic actuators 14, 15, 16 of the injection machine for each stage of the injection molding process are calculated and placed on the controller 22 for each step of the slave motor. The motor unit 40 includes a value motor 41 and a rotation sensing element 42 connected to the motor shaft center. The word service motor 41 includes, but is not limited to, an induction ship motor or a synchronous feeding service motor. The rotation probing element 42 includes, but is not limited to, an encoder, a resolver, and a tachometer. The rotation sensing component 42 senses the measured value generated by the rotation speed of the servo motor 41, and feeds back the control 22 of the drive control device 20. The controller 22 compares the measured value with the specified value to generate a control. The command signal of the inverter 21 is used to change the frequency of the inverter 21. The hydraulic pump 50 is preferably an energy-saving and power-saving effect, including but not limited to an internal gear hydraulic pump and a plunger hydraulic pump. The beta accumulator 6G is connected to the fluid unit 5 and the secret unit 51 of the injector. 5, the force switch 7Q is connected to the accumulator 6Q for controlling the pressure accumulating action of the accumulator. 'The firm switch 0 has the upper and lower limit adjustment function, or the two force switch is used to adjust the upper and lower limits. According to the above, the 'face transfer relay 2G energy motor unit 4Q connection, inverter ^, Xuan control a 22 Under the command, the specific fresh squid is supplied to the electric motor such as the feeding motor 41', and the escort motor 41 is operated at a specific rotation speed with the curve. At the same time, the rotation sensing component 42 feeds back the actual speed signal of the motor 41 to the controller a. The controller 22 analyzes the actual speed of the riding speed and analyzes the result, and compares the result of the analysis into a command signal. After being transmitted to the inverter Μ, the output frequency of the inverter 2] is corrected accordingly, and the rotational speed of the motor 41 is corrected. The ship motor 41 drives the hydraulic system 50 connected thereto to operate, and drives the liquid dust oil to be outputted to the accumulator 6 at a specific flow rate for storage and storage, reading and re-transporting the various components of the oil passage unit 51.
