Description

Die casting machine integrated form injection oil hydraulic cylinder
Technical field
The utility model relates to a kind of die casting machine integrated form injection oil hydraulic cylinder.
Background technique
Die casting machine requires in injection process, the shot piston of injection oil cylinder travels forward at a slow speed earlier, high-speed motion carries out fast shot then, finish when filling type, when oil pressure is elevated to setting value in the injection cylinder, the charged piston motion of pressurizing cylinder is carried out supercharging, so die casting machine has shot piston and charged piston.The injection oil cylinder and the pressurizing cylinder of existing die casting machine are separately independently, add that hydrovalve generally is installed on the die casting machine body, so all need to be connected between the oil cylinder, between the hydrovalve and between hydrovalve and the oil cylinder by oil-piping, cause the injection part-structure loose, complicated, all bring some inconvenience for installation, maintenance.
The model utility content
The purpose of this utility model is to propose a kind of compact structure, simple die casting machine integrated form injection oil hydraulic cylinder.
For achieving the above object, concrete technical measures of the present utility model are as follows: this oil hydraulic cylinder has the hollow valve body that double as is a hydraulic cylinder body, is provided with the oil circuit that is communicated with between the hydrovalve that places on the valve body in the hollow valve body wall; Be provided with the shot piston and the supercharging floating piston that are complementary in the hollow valve body chamber, the hollow valve body two ends respectively are provided with end cap, and the injection rod of shot piston stretches out from the end cap of its residing end.
Above-mentioned supercharging floating piston is formed by connecting by charged piston and floating piston, floating piston be through-rod piston and be in charged piston and shot piston between.
Above-mentioned injection cylinder cap and pass between the injection rod of shot piston wherein and be provided with the sleeve pipe that is fixed on the injection inboard wall of cylinder cover.
Oil circuit in the above-mentioned hollow valve body wall comprises injection in-line on the cylinder body position between injection oil circuit, shot piston and the supercharging floating piston on the cylinder body position of contiguous shot piston end caps, reaches the supercharging in-line on the charged piston one end end cap.
Hollow valve body double as hydraulic cylinder body of the present utility model, required hydrovalve are connected on the hollow valve body and form the valve piece, and the utility model is because valve piece, injection cylinder body and supercharging cylinder body are integrated, so integrated degree height, compact structure is simple, and the space of being occupied is little, beautiful shape.The utility model is rationally distributed, and the pressure loss is little, the good stability of system.Suitable especially the use on by computer-controlled full-automatic die casting machine.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below according to a particular embodiment of the invention and in conjunction with the accompanying drawings, the present invention is further detailed explanation, wherein
Fig. 1 is the example structure diagrammatic sketch;
Fig. 2 is embodiment's External view;
Fig. 3 is the A-A sectional view of Fig. 1;
Fig. 4 is the through-rod piston diagrammatic sketch of supercharging floating piston;
Fig. 5 is the piston head diagrammatic sketch of supercharging floating piston.
Embodiment
Fig. 1 has hollow valve body to embodiment shown in Figure 5, and hollow valve body 1 profile is block.The Hydraulic Power Transmission System of die casting machine is to need various hydraulic control valves control liquid flow path direction, pressure and flow, is connected with required relevant hydrovalve on the valve body 1 and forms the valve piece, is processed with the oil circuit that is communicated with between each valve on the valve body wall.Hollow valve body 1 double as is the injection cylinder cylinder body, in the chamber of hollow valve body 1 also is to be provided with shot piston 4 and the supercharging floating piston 5 that is complementary with cavity in the chamber of cylinder body.The two ends of hollow valve body 1 are that the two ends of cylinder body 1 are respectively equipped with end cap 2 and end cap 3.The injection rod 4-1 of shot piston 4 stretches out from the end cap 2 of its end of living in, this end cap 2 and pass between the injection rod 4-1 of shot piston wherein and be provided with the sleeve pipe 6 that is fixed on injection cylinder cap 2 inwalls, and the injection rod 4-1 of shot piston 4 and sleeve pipe 6 are movingly.Supercharging floating piston 5 is formed by connecting by screw by charged piston 5-1 and floating piston 5-2, and floating piston 5-2 is a through-rod piston, and is between charged piston 5-1 and the shot piston 4.
Oil circuit in the hollow valve body wall comprises injection in-line 1-2 on the cylinder body position between injection oil circuit 1-1, shot piston 4 and the supercharging floating piston 5 on the cylinder body position at contiguous shot piston end cap 2 places, reaches the supercharging in-line 3-1 on the charged piston 5 one end end caps 3.Supercharging in-line 3-1 connects injection control valve 7.
When injection, because injection in-line 1-2 is between shot piston 4 and the supercharging floating piston 5, injection oil is promoting the 4 proal whiles of shot piston like this, stops supercharging floating piston 5 to travel forward.When beginning during supercharging, the supercharging aperture is opened, and pressurised oil promotes the supercharging floating piston advances, with propagation of pressure to the injection rod 4-1 of shot piston 4.
