Summary of the invention
The technical problem that the utility model will solve is: overcome the deficiency of prior art, provide a kind of and realize fast, accurately conversion, injection machine matched moulds, locked mode simple in structure are changed hydraulic cylinder automatically with stroke between the stroke at a slow speed.
The utility model solves the technical scheme that its technical problem adopted: this injection machine matched moulds, locked mode are changed hydraulic cylinder automatically with stroke, comprise hydraulic cylinder, it is characterized in that: installation and combination structure piston in the described hydraulic cylinder; The combining structure piston is to form at the inner suit valve piston of big piston, two chambeies about big piston is divided into hydraulic cylinder inside, and big piston one end is provided with the perforation oil groove; The other end stretches out the hydraulic cylinder outside; The valve piston inner hollow, an end stretches out the hydraulic cylinder outside, and the end is provided with external screw thread; The afterbody correspondence of hydraulic cylinder is provided with internal thread, and clamp nut is installed at the external screw thread place of valve piston.
Said valve piston stretches out on the end face of the outside end of hydraulic cylinder and has oil-in.
Top, two chambeies correspondence is provided with left chamber oil-in and right chamber oil-in about described hydraulic cylinder.
Compared with prior art, the beneficial effect that the utility model had is:
1, simple in structure, reduce cost: on the fluid pressure type injection machine, adopt this device that matched moulds, locked mode are unified with the mode transfer process; Save independent mould adjusting mechanism; Simplified the structure of injection machine; Reduce the length dimension of injection machine, reduced the outfit of hydraulic injection molding machine station flow, reduced the manufacturing cost of injection machine main frame.
2, soon, stroke is freely changed at a slow speed: because it adopts particular structural, can realize dynamic model by quick-make at a slow speed closed, again to the automatic conversion of pressurize locked mode process, conversion conveniently, flexible; Than the toggle injection machine; Through control hydraulic system pressure and flow, just can regulate matched moulds, locked mode speed and clamp force easily, with the realization speed and vigor accurate control; Easy to operate, flexible, practical.
Description of drawings
Fig. 1 is the utility model structural front view sketch map.
Wherein: 1, valve piston 2, clamp nut 3, hydraulic cylinder 4, big piston 5, perforation oil groove 6, oil-in 7, left chamber oil-in 8, right chamber oil-in.
Fig. 1 is the most preferred embodiment of the utility model, further specifies below in conjunction with 1 pair of the utility model of accompanying drawing:
The specific embodiment
With reference to accompanying drawing 1:
This injection machine matched moulds, locked mode are changed hydraulic cylinder automatically with stroke; Comprise valve piston 1, clamp nut 2, hydraulic cylinder 3, big piston 4, connect oil groove 5, oil-in 6, left chamber oil-in 7 and right chamber oil-in 8; Installation and combination structure piston in the hydraulic cylinder 3; The combining structure piston is to form at big piston 4 inner suit valve pistons 1; Two chambeies about big piston 4 is divided into hydraulic cylinder 3 inside, about 3 two top, chamber correspondences of hydraulic cylinder are provided with left chamber oil-in 7 and right chamber oil-in 8, and the afterbody of hydraulic cylinder 3 is provided with internal thread.
Big piston 4 one ends are provided with and connect oil groove 5, and the other end stretches out hydraulic cylinder 3 outsides, valve piston 1 inner hollow; Constitute the oil inlet and outlet of small cylinder; One end stretches out hydraulic cylinder 3 outsides, and the end is provided with external screw thread, and the afterbody correspondence of hydraulic cylinder 3 is provided with internal thread; Clamp nut 2 is installed at the external screw thread place of valve piston 1, and valve piston 1 stretches out on the end face of hydraulic cylinder 3 outside ends and has oil-in 6; Valve piston 1 one ends stretch out hydraulic cylinder 3 outsides, and valve piston 1 stretches out the outer spiral shell of the outside end of hydraulic cylinder 3, screw through the internal thread with the afterbody of hydraulic cylinder 3, change the axial location of valve piston 1 relative big piston 4, and fix through clamp nut 2.
The course of work is following:
The utility model is when work, and high-pressure and hydraulic oil gets into big piston 4 inner chambers through the oil-in 6 of valve piston 1 end with valve piston 1 inner cavity, because big piston 4 cavity volume are less; Can directly drive big piston 4 rapid movements,, and then realize the rapid movement of mould again owing to big piston 4 and moving platen are fixedly connected; In big piston 4 fast moving, the hydraulic oil in the fuel tank is inhaled into the left chamber in the hydraulic cylinder 3 through prefill valve, left chamber oil-in 7, and big piston 4 moves to the right chamber of hydraulic cylinder thus; Move right in the process at big piston 4, when the perforation oil groove 5 on the big piston 4 arrived valve piston 1 right-hand member, big piston 4 inner chambers were communicated with the left chamber of hydraulic cylinder; The high-pressure and hydraulic oil of big piston 4 inner chambers gets into chamber, a hydraulic cylinder left side, and oil pressure raises in the chamber, a hydraulic cylinder left side, and prefill valve cuts out; Big piston 4 motion is automatically by converting at a slow speed fast, thus, realized the matched moulds motion soon, conversion automatically at a slow speed; After the complete closure of dynamic model, promptly get into the locked mode packing stage.
As shown in Figure 1, valve piston 1 end is provided with external screw thread, when unclamping clamp nut 2; Rotate valve piston 1; Valve piston 1 screws through the internal thread with hydraulic cylinder 3 afterbodys, can make valve piston 1 relative big piston 4 move left and right on axis direction, has changed valve piston 1 with respect to the position that connects oil groove 5 on the big piston 4; The position of big piston 4 when promptly changing the intercommunication of chamber, big piston 4 an inner chambers and hydraulic cylinder left side; Can correspondingly adjust the travel position when changing between big piston 4 fast moving and the microinching, tighten clamp nut 2 subsequently, the position of locking valve piston 1.
In addition, matched moulds and opening speed are confirmed by the flow of the speed controlling components set of hydraulic system, through the flow of regulator solution pressing system, are just reached the purpose of regulating matched moulds, opening speed easily; The setting pressure that mold clamping force and clamp force are set by hydraulic system is confirmed, the pressure that the regulator solution pressing system is set just reaches the purpose of regulating matched moulds, clamp force size easily.
The above; It only is the preferred embodiment of the utility model; Be not to be the restriction of the utility model being made other form, any professional and technical personnel of being familiar with possibly utilize the technology contents of above-mentioned announcement to change or be modified as the equivalent embodiment of equivalent variations.But every the utility model technical scheme content that do not break away to any simple modification, equivalent variations and remodeling that above embodiment did, still belongs to the protection domain of the utility model technical scheme according to the technical spirit of the utility model.
