Description
Technical field
The utility model relates to a kind of injection machine injection integrating device, comprises valve plate and solenoid directional control valve, and said valve plate top is provided with the variable frequency hydraulic pump, belongs to the injection machine field.
Technical background
In injection machine machinery industry, the employed hydraulic pump of existing injection machine generally all adopts constant hydraulic pump, but the entire work process of injection machine stage by stage; Each stage, needed hydraulic pressure was different; But, cause the pressure of whole link of injection moulding identical, therefore because the fuel delivery of oil sources hydraulic pump is constant; All installed overflow valve on the present injection machine additional; When pressure is higher than required pressure, be releasable energy through overflow valve, make hydraulic pump only need satisfy the pressure demand that maximum pressure can be realized whole links.But, can only drain for the energy that overflow valve discharged, waste a lot of energy.Waste present situation that how can injection moulding industry now need be from multi-faceted, and multi-angle is weighed the whole injection moulding process of injection machine.
The utility model content
In order to overcome above problem, the utility model provides a kind of injection machine injection integrating device, can overcome the above defective, realizes the purpose of energy savings.
For solving above technical problem, the utility model provides following technical scheme: a kind of injection machine injection integrating device, comprise valve plate and solenoid directional control valve, and said valve plate top is provided with the variable frequency hydraulic pump.
Further, said valve plate is positively connected with inserted valve, cover plate and solenoid directional control valve, and said inserted valve directly is connected on the valve plate, and cover plate is located between inserted valve and the solenoid directional control valve.
Further, said valve plate side connection tubular type check valve and free flow coupling.
Further, the bar jointing is moved back in said valve plate side tubular type check valve closer connection.
This injection machine injection integrating device that the utility model relates to carries out frequency control to oil pump, and constant displacement pump is changed into the like variable pump characteristics.When system demand pressure is higher, Oil pump electrical machinery 50Hz operation, required pressure hour, frequency converter frequency reducing operation.Shaft power and the outlet pressure of oil pump and the product direct ratio of flow of motor output, after the Oil pump electrical machinery rotating speed reduced, output shaft power reduced, and just can reach effectively energy-conservation, and general power saving rate is 20% ~ 50%.

The specific embodiment
As shown in Figure 4, a kind of injection machine injection integrating device comprises valve plate and solenoid directional control valve, and said valve plate top is provided with the variable frequency hydraulic pump.Utilize injection machine synchronizing signal and electric control system; According to the technological requirement of injection mo(u)lding,, be modeled to load tracking control system with electro-hydraulic proportional control system; The rotating speed of Oil pump electrical machinery is directly proportional with the pressure product with the flow of the required hydraulic pressure of injection machine work; Traditional constant displacement pump is transformed into the variable frequency hydraulic pump, thereby makes the oil return flow of overflow valve drop to minimum, no high pressure throttling energy loss; And then there is " energy-dissipating type " injection machine of high pressure throttling to upgrade to " energy-saving " injection machine of no high pressure throttling the tradition
Valve plate 1 is positively connected with inserted valve 9, cover plate 10 and solenoid directional control valve 8, and valve plate 1 bottom also is connected with inserted valve 3, cover plate 4 and solenoid directional control valve 5, and the above inserted valve all directly is connected on the valve plate 1, and cover plate is located between inserted valve and the solenoid directional control valve.The inserted valve volume is little, and make-break capacity is strong, and flow is big, is used in this structure the pressure that can the better utilization oil pump brings.
Valve plate 1 side connects tubular type check valve 18 and free flow coupling 19.The use of check valve 18 can be played the effect of energy savings at this, and instantaneous pressure increases when moving back bar, and check valve can discharge certain energy and be back to again in the valve plate, plays cushioning effect, and can energy savings.
All free flow couplings shown in Fig. 1-5 are for connecting the pipe joint of hydraulic control system, for next process provides power.
This injection machine injection integrating device that the utility model provides, volume is little, light weight, and energy savings.
The described specific embodiment of the utility model does not constitute the restriction to the application's scope; Within every spirit in the utility model design and the principle, any modification that one of skill in the art can make, be equal to and replace and improvement etc. all should be included within the protection domain of the utility model.
