The position and its condition of work of machine construction and injection chamber (hereinafter referred to as pressure chamber) are classified.
Die casting machine is divided to hot press chamber die casting machine and the major class of cold pressing chamber die casting machine two.Cold pressing chamber die casting machine presses its pressure chamber structure and cloth
Put mode and be divided to horizontal, vertical two kinds of forms again.The clamping of hot press chamber die casting machine and cold pressing chamber die casting machine is the same, its area
It is not that injection, casting mechanism are different.The pressure chamber of hot press chamber die casting machine is closely linked to be an entirety with smelting furnace, and is cold-pressed chamber pressure
The pressure chamber of casting machine is to separate with smelting furnace.
The shot piston of die casting machine injection cylinder is used to connect injection rod to carry out injection effect, and the connection of shot sleeve rear portion increases
Cylinder pressure, pressurized cylinder are used to connect fuel tank, and fuel tank is provided with magnetic valve, and PLC controls the opening and closing of magnetic valve, to control hydraulic pressure
Oil enters back into shot sleeve into pressurized cylinder, and hydraulic oil driving shot piston is stretched.In the prior art, pressurized cylinder passes through pressure regulation
The rotation of valve rod controls hydraulic oil to enter in pressurized cylinder, and the hydraulic oil of pressurized cylinder entered back into shot sleeve to drive injection rod to move
Make, current valve rod is all solid round bar, and solid round rod is used to stop oil inlet passage, led to by rotation valve rod to adjust oil-feed
The aperture in road is to adjust the The hydraulic oil of entrance, and hydraulic oil is directly entered in the booster cavity of pressurized cylinder when the pressure regulation method is adjusted,
The unexpected pressure increase of booster cavity can produce certain vibrations to shot sleeve, influence shot sleeve service life.
Utility model content：
Technical problem to be solved in the utility model is to overcome existing technological deficiency, there is provided a kind of die casting machine supercharging
Cylinder regulator.
Technical problem to be solved in the utility model is realized using following technical scheme：
A kind of die casting machine pressurized cylinder regulator, including pressurized cylinder, the cavity back of the pressurized cylinder are provided with hollow
Cylinder, cylinder is anterior to be provided with several through holes around its side wall, inner barrel be coaxially provided with it is equal with its internal diameter it is anterior seal,
The hollow pressure regulation bar of afterbody opening, pressure regulation bar afterbody are connected with pressing plate, and pressing plate is connected with the externally threaded rotating bar of outer wall belt, turn
Lever passes pressurized cylinder and coordinated with pressurized cylinder screw thread.
Further, the rotating bar passes one end of pressurized cylinder and is provided with turning handle.
Further, the pressure regulation bar internal cavities are inserted with spring.
Further, the pressure regulation bar outer wall offers some circle grooves, is provided with sealing ring in groove, at the top of sealing ring and
Adjusting rod outside wall parallel.
Further, the barrel front end and rear end are provided with groove of the circle along its outer wall, and sealing is provided with groove
Circle.
The beneficial effects of the utility model are：By rotate rotating bar drive adjusting rod along inner barrel it is movable with
The aperture of through hole is adjusted, so oil enters into cylinder cavity from through hole and then enters back into shot sleeve, and such oil can be uniform
Entered from through hole in cylinder cavity and it is gentle enter shot sleeve, mitigate the impact to shot sleeve significantly, improve shot sleeve
Service life.
Brief description of the drawings：
Fig. 1 is the structural representation of the utility model one embodiment；
Fig. 2 is the schematic cross-section of through hole cylinder in the utility model one embodiment；
Fig. 3 is the structural representation of another embodiment of the utility model.
