Description
Technical field
The present invention relates to a kind of injection machine injection integrating device, comprise valve plate and solenoid directional control valve, described valve plate top is provided with variable frequency hydraulic pump, belongs to injection machine field.
Technical background
In injection machine machinery industry, the hydraulic pump that existing injection machine uses generally all adopts constant hydraulic pump, but the whole course of work of injection machine stage by stage, needed hydraulic pressure difference of each stage, but because the fuel delivery of oil sources hydraulic pump is constant, cause the pressure of whole link of injection moulding identical, therefore, on present injection machine, all install overflow valve additional, when pressure is during higher than required pressure, be releasable energy by overflow valve, make hydraulic pump only need meet maximum pressure can to realize the pressure demand of whole links.But the energy discharging for overflow valve can only be drained, waste a lot of energy.How now the waste present situation of Injection Industry, need to be from multi-faceted, and multi-angle is weighed the whole injection moulding process of injection machine.
Summary of the invention
In order to overcome above problem, the invention provides a kind of injection machine injection integrating device, can overcome the above defect, realize the object of saving the energy.
For solving above technical problem, the invention provides following technical scheme: a kind of injection machine injection integrating device, comprise valve plate and solenoid directional control valve, described valve plate top is provided with variable frequency hydraulic pump.
Further, described valve plate is positively connected with inserted valve, cover plate and solenoid directional control valve, and described inserted valve is directly connected on valve plate, and cover plate is located between inserted valve and solenoid directional control valve.
Further, described valve plate side connects tubular type check valve and free flow coupling.
Further, described valve plate side tubular type check valve connects more nearby and moves back bar jointing.
This injection machine injection integrating device the present invention relates to, carries out frequency control to oil pump, and constant displacement pump is changed into 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 Oil pump electrical machinery rotating speed reduces, output shaft power reduces, and just can reach effectively energy-conservation, and general power saving rate is 20% ~ 50%.

Detailed description of the invention
As shown in Figure 4, a kind of injection machine injection integrating device, comprises valve plate and solenoid directional control valve, and described valve plate top is provided with variable frequency hydraulic pump.Utilize injection machine synchronizing signal and electric control system, according to the technological requirement of injection mo(u)lding, by electro-hydraulic proportional control system, be modeled to load tracking control system, the rotating speed of Oil pump electrical machinery and the flow of the required hydraulic pressure of injection machine work are directly proportional to pressure product, traditional constant displacement pump is transformed into variable frequency hydraulic pump, thereby make the oil return flow of overflow valve drop to minimum, without 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 without high pressure throttling 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 is also connected with inserted valve 3, cover plate 4 and solenoid directional control valve 5, and the above inserted valve is all directly connected on valve plate 1, and cover plate is located between inserted valve and solenoid directional control valve.Inserted valve volume is little, and make-break capacity is strong, and flow is large, is used in the pressure that can better utilize oil pump to bring in this structure.
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 saving the energy at this, and in the time moving back bar, instantaneous pressure increases, and check valve can discharge certain energy and again be back in valve plate, plays cushioning effect, and can save the energy.
All free flow couplings shown in Fig. 1-5 are the pipe joint of connecting fluid pressure control system, for next process provides power.
This injection machine injection integrating device provided by the invention, volume is little, and quality is light, and saves the energy.
Detailed description of the invention of the present invention does not form the restriction to the application's scope; every within the spirit and principle of the present invention design, any amendment that one of skill in the art can make, be equal to and replace and within improvement etc. all should be included in protection scope of the present invention.
