Abstract
The utility model discloses energy-saving devices for the plastic injection machine, comprising a frequency conversion device and a computer control device. The frequency conversion device connects with the oil pump electric motor of the plastic injection machine. The computer control device, which connects with the frequency conversion device, controls the output power of the oil pump electric motor, and connects with the pressure valve and overflow valve of the oil pump. Taking the actual required pressure and flux signals of the plastic injection machine in different phases as the control signals of the oil pump electric motor output power, the computer control device orders the oil pump electric motor through frequency conversion device to modulate the rotate speed and supply energy according to the oil pressure and flux burthen in actual injection. Due to employment of the utility model, the output power of the oil pump electric motor is kept consistent with the actual required burthen in different phases of working process. Comparing with the hydraulic pressure plastic injection machine, the electric motor output power is greatly decreased, thus the energy is saved.
Description
Affiliated technical field
The utility model relates to a kind of energy conservation apparatus of plastic jetting-moulding machine, is the energy saver that is applicable on the fluid pressure type injection machine.
Background technology
The fluid pressure type injection machine is a kind of typical cyclical movement load equipment, and a complete production cycle comprises the stages such as locked mode, injection, melten gel, cooling, die sinking, and pressure, the traffic demand of each stage to its hydraulic system is very different.Current hydraulic injection molding machine commonly used, the power of its Oil pump electrical machinery is to be equipped with according to peak load in the injection machine running, fuel pump speed is non-adjustable during work, and power output immobilizes, and required oil pressure, the flow of injection moulding only regulate by overflow by pressure valve, the overflow valve of reliable oil pump.Because each stage required payload of injection machine in each work period differs, maximum during as locked mode, melten gel is less when injection, die sinking, and cooling stage approaches zero.In the injection moulding course of work, the energy loss of Oil pump electrical machinery is serious like this, and the utilization rate of electric energy only has 30-70%.Therefore, common fluid pressure type injection machine energy consumption is very big.
Summary of the invention
When working in order to solve existing fluid pressure type injection machine, fuel pump speed is non-adjustable, power output immobilizes, the required oil pressure of injection moulding, flow be the pressure valve, the deficiency that overflow valve is regulated by overflow of reliable oil pump only, the energy conservation apparatus of plastic jetting-moulding machine that the utility model provides, the adjustable-speed of oil pump during injection machine work, power output and injection machine in each work period the actual demand in each stage suitable, required pressure, the flow of injection moulding do not rely on the pressure valve of oil pump, overflow valve to regulate by overflow.
The energy conservation apparatus of plastic jetting-moulding machine that the utility model provides, it comprises frequency-conversion processing device and computer controller, the frequency-conversion processing device links to each other with the injection machine Oil pump electrical machinery, the computer controller that connects the frequency-conversion processing device, and be connected with pressure valve, the overflow valve of oil pump, computer controller is with oil pressure, the flow signal of each stage actual demand of a work period of injection machine, control signal as the output of Oil pump electrical machinery power, adjust rotating speed by frequency-conversion processing device instruction injection machine Oil pump electrical machinery, by pressure, the traffic load energize of injection moulding reality of work demand.
Owing to adopted the technical solution of the utility model, required payload of the power output of injection machine Oil pump electrical machinery and each stage of the injection machine course of work is identical, compare with common hydraulic injection molding machine, significantly reduced the motor power output, save electric energy and reach 25-50%.Simultaneously, because Oil pump electrical machinery real-world operation amount has reduced, obtain service life prolonging; Reduce hydraulic oil temperature, slowed down the aging of oil, reduced maintenance cost.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model circuit connecting relation schematic diagram.
1. Oil pump electrical machineries among the figure, 2. frequency-conversion processing device, 3. computer controller, 4. pressure fuel pump valve, overflow valve, 5. record, display unit.
The specific embodiment
In Fig. 1, the utility model hydraulic injection molding machine is on the Oil pump electrical machinery 1 of common hydraulic injection molding machine, and connection is provided with a frequency-conversion processing device 2 that adapts with it; The computer controller 3 that connects frequency-conversion processing device 2, and be connected with pressure valve, the overflow valve 4 of oil pump.Before entering energy-saving run, computer controller 3 is the start detection device at first, oil pressure, the data on flows detect, the former injection machine of record moved each stage actual demand of a work period, be the control signal of Oil pump electrical machinery 1 power output then with this data conversion, and be kept in the computer controller 3.When entering energy-saving run, the control signal that computer controller is exported the Oil pump electrical machinery power of preserving repeatedly, according to hydraulic injection molding machine real-world operation state, adjust rotating speed by frequency-conversion processing device 2 instruction injection machine Oil pump electrical machineries 1, by pressure, the traffic load energize of corresponding injection moulding reality of work demand, support injection machine to finish the injection moulding work of each work period repeatedly.
In order to understand the energy-conservation situation of injection machine, energy-conservation record, display unit 5 are set on computer controller 3, by switching energy-conservation and non-power down switch, the electricity consumption data of energy-saving run state or non-power save mode just can obtain showing fully aware ofly like this.
In order to realize the soft start of motor, " S " type that in computer controller, is provided with the motor special use start curve, 21 kinds of V/F torque magnification modes, stepless speed regulation and 0.2-3200 second broad-adjustable acceleration time selection instruction; Also be provided with simultaneously Oil pump electrical machinery is carried out defencive functions such as overcurrent, overvoltage, overload, under-voltage, overheated, CPU.
Owing to adopted the technical solution of the utility model, compare with common hydraulic injection molding machine, save electric energy and can reach 25-50%, can realize the soft start of motor, can prolong electrical machinery life, slow down oil ageing, reduce maintenance cost.
