New Description·· 【New Technical Fields】 This creation is about the driving technology of an injection machine. Specifically, it refers to an injection machine driving device that can compensate for output and achieve energy saving. Improve the quality of product molding. [Prior Art] According to the injection molding, it is a characteristic of the quality of soybeans commonly used in polymer processing. The well-known injection molding Ao Fan & Bean is tired, i + 曰埤 uses hydraulic oil as the driving source, f oil power source is driven by the induction motor to drive the hydraulic pump to rotate, and the pump oil generates tender flow Through the various types of parts on the oil system, two or two pieces of control are controlled to complete the various processes of injection molding. The complete injection molding θ mode, injection, metering, mold opening, ejection and cooling procedures, the flow rate and pressure of the hydraulic oil of each program are not the same [as shown in the figure], Xi: ratio: pressure valve The proportional flow valve is matched with the directional valve of the oil circuit system, the flow and the force of the logic [as shown in Figure 2]. The motor of the induction motor (4) the number of poles of the motor and the frequency of the power supply (4), in the conventional case, 'the motor is operated at a fixed speed after starting the motor, providing a fixed amount of hydraulic oil discharge ^, into the cycle, The hydraulic oil flow required by each program is different. For example, the proportion of the whole cycle time is quite large. :: Day: Need to use, oil, and use the induction motor to drive the hydraulic spring to rotate. ? Fixed in the stream of life, the hydraulic oil that failed to be used flows directly back to the oil phase~ the waste of this source, and the efficiency of the hydraulic oil temperature rises to reduce the overall plow σ and i Chengxin & Energy, can use the frequency conversion "engineering motor early 兀 speed 'in accordance with the hydraulic oil flow demand does not rotate the speed ' drive the oil fruit to produce different hydraulic pressure. 4 sheep - M342262 provides high torque for pressure holding and high pressure clamping mode, and the speed reaches the higher speed to increase the height: to r pressure, high flow - its large, motor aging, etc. due to low The torque at the speed of rotation changes with the environmental force of the liquid output / (a) does not determine, its rotation (four) after the pump shown, the conventional injection: two = the stability of the molded product. And as shown in Figure 3, the amount of hydraulic oil that has not been used is only passed through the 4th valve of the 啰里, because the required flow rate is smaller than the pressure protection door UZ.. ^, so that the pressure builds up, making the ratio The remaining (4) oil and oil return tank, this is a waste of energy. + Republic of China Patent Bulletin No. 154〇〇3, ,, inverter, motor and pressure sensor, using pressure; === feeding to the controller, than grabbing - 々 ^... A profit to return to the oil pump Really as the control of the motor speed. When detecting the bow light, two: set value, the controller sends a speed increase command, so that == handle plus 'use the high torque of the motor high speed torque' to provide the hydraulic pressure required for actuation . Using high speed, there is r::, however, for the injection machine in the pressure holding or high-pressure clamping stage, it is necessary to strictly demand the strong energy, but the pressure and flow should be directly returned to the second, the oil Under high pressure, no energy is driven because the energy consumed by it is wasted. In addition, as shown in Figure 4, the member D rate controls the motor speed, and controls the pump discharge amount at a speed of 1f夂. Due to the motor response and the oil system's = port response: rapid changes in the process of action change, failed to stabilize; ash in the Republic of China patent publication No. 1259138, as shown in Figure 5, the molding machine frequency conversion energy saving and improve production efficiency control system, The system setting ^ M342262 on the motor characteristics of today ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ In the lowest material control system 'command the frequency converter to increase the frequency; the second low-grade turn to the house. Although this method can be based on the flow: the torque is supplied because of the motor characteristics, when the pressure is insufficient, the frequency is required. However, when the injection is transferred to the waste, the speed, & I speed is increased by the use of the algorithm. The algorithm will drive the required pressure at the lowest frequency but rises. If the dust is insufficient, the controller points: liter = enough The pressure. When the standby speed is increased to increase the torque, the middle turn ^, the rising frequency, the drive motor unit is transformed, which seriously affects the quality. 'Poor & will cause the injection of discontinuity. Another 'People's Republic of China patent - for energy saving or production efficiency of liquid materials; 183:: 'It reveals the system, control the output frequency of the inverter to change the electricity == profit “Knowledge hydraulic system's wheel flow and pressure; its characteristics are pre-entered to control hydraulic machinery as a reference for control. Its system is shown in Fig. 6. The working condition of the engine is used to know the speed signal, which can reduce the speed conversion n: Influencing the molding quality. This method uses the open circuit =;; the action is not continuous, due to the operating environment, motor use time, liquid job, hydraulic mechanical system will r, a„, ^^t; s^^ ;; 7^ ;;" ' Line compensation, will seriously affect the molded article #. ^Shuangxing measurement and advancement to the problems of the prior art to be overcome: Moment height = two force production: gas two due to the characteristics of the motor unit, the use of high-torque reflow to the end == force street towel oyster sauce, are direct ( 2) The controller passes the pressure measurement α to measure whether the sensing actuation pressure is sufficient. If the pressure of the M342262 is insufficient, the motor unit speed is increased, and the high-speed starting pressure value is used to cause the energy wave described in (1) to be f& Twist (four) increase insufficient ~ into continuous material, seriously affecting the quality of the molded product. ^Speed (Mountain 3)> The night pressure mechanical system will change with the accumulation of operating time. At the private measurement of the variation and the compensation will cause the system to go to the right. It can be seen from the above that in the technology, it is impossible to balance the balance of the two σ, and the application range is greatly reduced. Ί In view of this, the creator has been engaged in the process of “experienced by the above-mentioned habits for many years”: the development of the sputum, and the recognition of the J&A;.":;Γ,?ΙΓ" ^f^ ^ - [New content] A series of phase t疋 and other inconveniences and troubles. = The second creation is mainly to provide an energy-saving operation of the injection machine to achieve the goal of Lang can and stabilize the system.

For the change, and the pressure maintaining process Need low flow, high pressure output characteristics L 4 lock oil tank pressure can be stabilized, you need to increase the speed, the pressure is unstable due to the torque output, resulting in pressure is not fixed == - Bay. At this time, the increase in speed will produce high In the actual day and night 1;] night £ oil will flow directly back to the fuel tank, which also produces waste of energy [Figure 4, this creation for the action characteristics of the injection molding machine, choose the ancient punching machine unit (3), Its characteristic curve is shown in Figure 10. The higher torque is provided, so that when the high pressure clamping and the pressure holding process are performed, the speed can be output to the rated flow, which is required for the completion of the program. :: The pressure can be stabilized during her production process. Between the rear end of the measuring valve (6) and the actuating hydraulic cylinder, the μ valve (5), (10) 'use the pressure sensing element (1)) to measure the ^^ sensing element edge to the microcomputer control 12 M342262 (1) 'Microcomputer control ϋ (1) Compare this signal with the set value and compensate for the pressure shortage to maintain the pressure stability during the molding process. This creation can provide low flow and high pressure hydraulic oil 'reduced energy waste; provide high response characteristics, and detect the actual operating pressure and compensate the closed loop control system to stabilize the quality of the molded product; and the pressure compensation value pair The database of measurements is modified to optimize the parameters of the secondary production cycle. This creation step-by-step can provide low-speed, high-torque, output, and drive hydraulic oil with high pressure and low speed through the high-performance motor unit. It can provide high-pressure and high-pressure in the injection machine protection stage and the pressure-locking stage. demand. By analyzing the pressure and speed requirements of each section in the process of injection molding, and using the data library corresponding to the motor speed and the motor unit speed in advance, the operating speed of the motor unit demand is calculated by the controller (four), and the controller commands the inverter to supply the speed. The frequency is given to the motor unit to drive the oil system to generate the hydraulic oil required for the injection process, reducing the flow rate of the undriven direct return to the fuel tank to save energy (4); and using the pressure sensing element to measure whether the μ force of the real ρ output is Reach the set value 'return to the control set to compensate for the difference, ^ use this compensation amount to correct the amount in the database to reduce the influence of the molded product caused by environmental factors. At the same time, this high-performance motor unit has a 4-inch color with high acceleration response. It is equipped with a closed loop control, and continues to make the speed and torque supplements in the New Zealand time, reducing pressure fluctuations and stabilizing the injection.
