The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4.
Vertical compression mould clamping booster body of the present utility model, comprise locking piston bar 8, tailgate 7, in the vertically sliding chamber 10 that fits in the tailgate 7 of described locking piston bar 8 left ends, it also comprises a pressurized fuel tank 1 and a pressurizing cylinder, described pressurizing cylinder is made up of supercharging valve plate 2, pressurised oil cylinder barrel 3, charged piston bar 4, pressurised oil cylinder cap 5, and described pressurizing cylinder is fixed on the tailgate 7 by pressurizing cylinder pull bar 9; Described pressurized fuel tank 1 is fixedly connected on tailgate 7 tops, and described pressurizing cylinder is positioned at centre bore 16 tops of pressurized fuel tank 1, also is provided with an adapter sleeve 6 between pressurizing cylinder and the tailgate 7; Described adapter sleeve 6 tops are connected with pressurised oil cylinder cap 5, adapter sleeve 6 bottoms are fixed in the hole 11 on the tailgate 7, described charged piston bar 4 sliding fitting in the cavity of forming by the centre bore 18 of pressurised oil cylinder barrel 3, pressurised oil cylinder cap 5 and adapter sleeve 6, described charged piston bar 4 is big up and small down stepped; Between the chamber 10 in described pressurized fuel tank 1 and the tailgate 7 asphalt channel that can intermittently open is arranged.
There is the asphalt channel that intermittently to open to be meant between the chamber 10 in described pressurized fuel tank 1 and the tailgate 7, described adapter sleeve 6 tops have some hydraulic fluid ports 17, and described asphalt channel is made of the centre bore 18 that some hydraulic fluid ports 17 reach the adapter sleeve 6 that is communicated with some hydraulic fluid ports.
Described charged piston bar 4 is up big and down small stepped.If charged piston bar 4 upper diameter are D, lower diameter is d, and pressurizing cylinder top hydraulic oil is P to the pressure of charged piston bar 4 upper surface unit ares
0, the pressure of the unit are of 10 pairs of charged piston bar 4 lower surfaces of chamber in the tailgate 7 is P
