Die casting machine injection system is the critical component that determines the die casting machine properties of product, and present traditional die casting machine adopts the three grades of injection systems in double loop that utilize the floating piston supercharging substantially.Floating piston in this injection, the pressurized construction and floating plug are installed, requirement on machining accuracy is higher, floating piston and floating plug are installed in the out-of-alignment situation, floating piston and floating plug conical surface Bel linear sealing effect are bad, reveal easily, cause the pressurize wild effect.Charged piston promotes floating plug and floating piston conical surface Bel linear sealing, and supercharging could begin, and causes pumping rate slow, builds the unfavorable phenomenons such as pressure time length.
The utility model content:
To be solved in the utility model is floating piston and floating plug is installed, requirement on machining accuracy is higher in the traditional floating piston supercharging, conical surface Bel linear sealing effect is bad when floating piston and floating plug disalignment, cause pumping rate slow, it is long to build the pressure time, the unsettled difficult problem of pressurize effect.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
The die casting machine injection pressurized construction, comprise shot piston, be located at the shot piston on the shot piston, be arranged on the snap ring of splitting that is positioned at the shot piston outside on the shot piston, the charged piston bar that is connected by nut with shot piston, be located at injection valve plate and the supercharging valve plate in the charged piston bar outside, the charged piston bar is provided with the supercharging guide pin bushing between supercharging valve plate and the injection valve plate, described injection valve plate is provided with the injection oil circuit, it is characterized in that: the die casting machine injection pressurized construction also comprises a fast shot valve plate that is located on the injection valve plate, a described fast shot valve plate is provided with the fast shot oil circuit, described injection valve plate and a fast shot valve plate are provided with a two-way plug-in valve, described two-way plug-in valve comprises two-way plug-in mounting choke valve and hydraulic control one-way valve, described two-way plug-in mounting choke valve is connected with the fast shot oil circuit by oil pipe, hydraulic control one-way valve be connected with the injection oil circuit by oil pipe.
The end of described charged piston bar is provided with charged piston.
Be provided with the supercharging cylinder sleeve between described charged piston and the supercharging valve plate.
The beneficial effects of the utility model are: floating piston and floating plug in the utility model cancellation injection, the supercharging, and external two-way plug-in valve replaces floating piston, and system's pumping rate is fast, build pressure time weak point, good sealing effect is difficult for revealing, and makes injection system pressurize effect more stable.
Description of drawings:
Fig. 1 is the utility model structural representation.
The specific embodiment:
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, the die casting machine injection pressurized construction, comprise shot piston 1, be located at the shot piston 2 on the shot piston 1, be arranged on be positioned at shot piston 2 outsides on the shot piston 1 split snap ring 3, the charged piston bar 5 that is connected by nut 4 with shot piston 1, be located at injection valve plate 6 and the supercharging valve plate 7 in charged piston bar 5 outsides, the charged piston bar is provided with supercharging guide pin bushing 8 between supercharging valve plate 7 and the injection valve plate 6, injection valve plate 6 is provided with injection oil circuit 9, the die casting machine injection pressurized construction also comprises a fast shot valve plate 10 that is located on the injection valve plate 6, one fast shot valve plate 10 is provided with fast shot oil circuit 11, described injection valve plate 6 and a fast shot valve plate 10 are provided with a two-way plug-in valve, two-way plug-in valve comprises two-way plug-in mounting choke valve and hydraulic control one-way valve, two-way plug-in mounting choke valve is connected with fast shot oil circuit 11 by oil pipe, hydraulic control one-way valve be connected with injection oil circuit 9 by oil pipe.The end of charged piston bar 5 is provided with charged piston 12.Be provided with supercharging cylinder sleeve 13 between charged piston 12 and the supercharging valve plate 7.
Injection, the floating piston in the supercharging and floating plug that the utility model cancellation is traditional, external two-way plug-in valve replaces floating piston, and charged piston is directly controlled pressurized effect, makes system's pumping rate fast, builds pressure time weak point.The fast shot oil circuit increases the opening and closing of a two-way throttle cartridge valve control fast shot oil circuit, and the injection oil circuit increases the opening and closing of a hydraulic control one-way valve control cover plate control injection oil circuit.Utilize the opening and closing of injection cavity pressure control two-way throttle cartridge valve and hydraulic control one-way valve control cover plate, when two-way plug-in valve was closed, its good sealing effect was difficult for revealing, and makes injection system pressurize effect more stable.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
