When injection machine four cylinder vertical compression two-plate clampings of the present invention are during at matched moulds; on the solid plate 2 of injection machine, mould moving cylinder 70 is installed; piston rod one end of mould moving cylinder 70 is fixed on moving platen 1, drives moving platen 1 to move to the direction of solid plate 2 under the effect of mould moving cylinder 70, realizes matched moulds.In matched moulds process, along with the movement of moving platen 1, because one end of the first locking piston bar 33 and the second locking piston bar 43 is all fixed on moving platen 1, therefore, first piston 32 and the second piston 42 move to the direction that deviates from solid plate 2.Along with the movement of first piston 32 and the second piston 42, the oil in the second oil pocket 7 flows in the first oil pocket 6 by the second side oil duct 322 and the first side oil duct 321; Oil in the 4th oil pocket 9 enters in the 3rd oil pocket 8 by the 3rd side oil duct 421.Because the diameter of the first motion bar 331 is less than the diameter of the second motion bar 332, and the equal diameters of the diameter of the second locking piston bar 43 and the first motion bar 331, therefore, first piston 32 and the second piston 42 move simultaneously and the process of mobile same distance in, the oil mass of extruding in the second oil pocket 7 be less than with the 4th oil pocket 9 in the oil mass extruded; And only cannot supplement by the oil entering in the second oil pocket 7 in the first oil pocket 6 space forming in the interior moving process of the first oil pocket 6, the oil mass of extruding in the 4th oil pocket 9 is greater than required supplementary oil mass in the interior moving process of the 3rd oil pocket 8.Thus, the interior unnecessary oil mass of the 4th oil pocket 9 can be flowed in the second oil pocket 7 by tube connector 5, move the oil mass in the space of formation for supplementing the first oil pocket 6, the interior required supplementary oil mass of the first cylinder body 3 just equates with the interior unnecessary oil mass of the second cylinder body 4, thereby, guarantee that generally hydraulic oil in first piston 32 and the second piston 42 both sides oil pockets realizes equivalent exchange circulation, made matched moulds motion quick, smooth and easy.
After matched moulds completes, while carrying out locked mode, in the first oil transportation channel 30 in the first motion bar 331, pass into hydraulic oil, hydraulic oil enters a side of the first valve port 101 through the first oil transportation channel 30.Under the effect of hydraulic oil, promote the first valve port 101, make whole the first spool 10 to the first side oil duct 321 1 side shiftings, until the first spool 10 matches with the first side oil duct 321, make the oil in the first oil pocket 6 disconnect and being communicated with the oil in the second oil pocket 7; Meanwhile, to the interior input hydraulic oil of the 3rd oil transportation channel 50 in the second locking piston bar 43, hydraulic oil enters a side of the second valve port 201 through the 3rd oil transportation channel 50.Under the effect of hydraulic oil, promote the second spool 20 to the 3rd side oil duct 421 1 side shiftings, until the second spool 20 matches with the 3rd side oil duct 50, make the 3rd oil pocket 8 disconnect and being communicated with the oil in the 4th oil pocket 9.Then to the first oil pocket 6 and the interior injection hydraulic oil of the 3rd oil pocket 8; hydraulic oil is acted on first piston 32 and the second piston 42; be that the first locking piston bar 33 and the second locking piston bar 43 drive moving platen 1, the mould finally closing between tight moving platen 1 and solid plate 2 provides enough clamp forces.
In the time that moving platen 1 needs die sinking, stop to the first oil pocket 6 and the interior injection hydraulic oil of the 3rd oil pocket 8, and to the interior input pressure oil of the second oil transportation channel 40, pressure oil enters the opposite side of the first valve port 101, under the effect of pressure oil, promote the first valve port 101, and drive whole the first spool 10 to moving away from the direction of the first side oil duct 321, the first spool 10 and the first side oil duct 321 are separated, and the first oil pocket 6 and the second oil pocket 7 are connected.Simultaneously, to the interior input pressure oil of the 4th oil transportation channel 60, pressure oil enters the opposite side of valve port 201, under the effect of pressure oil, promote the second valve port 201, and driving whole the second spool 20 to moving away from the direction of the 3rd side oil duct 421, the second spool 20 and the 3rd side oil duct 421 are separated, and the 3rd oil pocket 8 and the 4th oil pocket 9 are connected.Then, drive moving platen 1 to moving away from the direction of solid plate 2 by mould moving cylinder 70, in moving process, drive the first locking piston bar 33, first piston 32, the second locking piston bar 43 and the second piston 42 to moving platen 1 place side shifting.Along with the movement of first piston 32 and the second piston 42, the oil in the first oil pocket 6 flows into the second oil pocket 7 by the first side oil duct 321 and the second side oil duct 322; Oil in the 3rd oil pocket 8 flows into the 4th oil pocket 9 by the 3rd side oil duct 421.Because the oil mass of the first oil pocket 6 interior discharges is greater than the interior required oil mass of the second oil pocket 7, the oil mass of the 3rd oil pocket 8 interior discharges is less than the interior required oil mass of the 4th oil pocket 9, therefore, oil mass unnecessary the first oil pocket 6 can be flowed into the 4th oil pocket 9 by tube connector 5 supplements, the interior unnecessary oil mass of the first cylinder body 3 just equates with the interior required supplementary oil mass of the second cylinder body 4, thereby, guarantee that generally hydraulic oil in first piston 32 and the second piston 42 both sides oil pockets realizes equivalent exchange circulation, made die sinking campaign smooth and easy fast.
To sum up, injection machine four cylinder vertical compression two-plate clampings of the present invention are in guaranteeing locked mode and shifting formwork, and pressure rising time when locked mode is short; easily realize rapid mould opening-closing; reduce energy consumption, reduced the shared space of locking piston bar, and saved the shared space of whole injection machine.
Above-described is only the preferred embodiment of the present invention, it should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise of the invention, can also make some distortion and improvement, and these all belong to protection scope of the present invention.
