Abstract
The utility model discloses a mould opening-demoulding linkage mechanism of an injection mould machine. The mould opening-demoulding linkage mechanism comprises a mould opening and closing oil cylinder and a demoulding oil cylinder, wherein an oil inlet of an oil cavity of the piston-free rod end of the mould opening and closing oil cylinder is provided with a first one-way valve; the first one-way valve is provided with an oil inlet pipe connected with an oil pump, an oil outlet of the oil cavity of the piston-free rod end of the mould opening and closing oil cylinder is connected with a linkage oil pipe, and one end of the linkage oil pipe is provided with a second one-way valve; The second one-way valve is arranged at the oil inlet of the oil cavity of the piston-free rod end of the demoulding oil cylinder, and the oil outlet of the oil cavity of a piston-free rod end of the demoulding oil cylinder is provided with an oil outlet pipe. According to the technical scheme, the mould opening and demoulding linkage mechanism provided by the utility model has the advantages that the return oil of the mould opening and closing oil cylinder in a mould opening process is utilized to push the demoulding oil cylinder to operate, a pressure regulator is arranged between the mould opening return oil and demoulding oil feeding and is used for changing the flow and the pressure, and thus the effect that a power source can control two execute components is achieved, the situation that the false operation of an electromagnetic valve of the demoulding oil cylinder damages the mould is avoided, the machine cost is also saved, and the energy consumption is reduced.
Description
Technical field
The utility model relates to a kind of injection moulding apparatus, relates in particular to a kind of die sinking, demoulding link gear of injection machine.
Background technology
In the general situation of fluid pressure type injection machine, only have a hydraulic system, a power source can only be provided, injection machine just can carry out next one action after only having completed an action.For example, after die sinking has been moved, just can carry out demoulding action.Injection machine, in order to shorten the production of articles cycle, improves productivity effect.A plurality of hydraulic systems of the normal employing of injection machine for providing injection machine a plurality of power sources, work a plurality of actions that do not affect mutually simultaneously, for example, increase a hydraulic system, do the demoulding action when can make die sinking action, shorten the production of articles cycle.For high-speed injection molding machine, the whole production of articles cycle is very short, saves more important that demould time shows.But still there is defect in this injection machine: a plurality of power sources are set the cost of injection machine is significantly increased, and between a plurality of power source, need solenoid control to carry out regular work, when maloperation appears in magnetic valve, be easy to mold damage.
Utility model content
In order to overcome defect of the prior art, the utility model provides a kind of die sinking, demoulding link gear that can prevent the injection machine of magnetic valve maloperation mold damage.
The utility model solves the technical scheme that its technical problem adopts:
The die sinking of injection machine, demoulding link gear, comprise folding mould oil cylinder and demoulding oil jar, the oil-in that it is characterized in that the piston-rodless end oil pocket of described folding mould oil cylinder is provided with the first check valve, on described the first check valve, the oil inlet pipe being connected with oil pump is installed, the oil-out of the piston-rodless end oil pocket of described folding mould oil cylinder is connected with interlock oil pipe, the second check valve is installed in one end of described interlock oil pipe, described the second check valve is arranged on the oil-in of the piston-rodless end oil pocket of described demoulding oil jar, the oil-out of the piston-rodless end oil pocket of described demoulding oil jar is provided with flowline.
As the further optimization to technique scheme, on described interlock oil pipe, booster is installed.
As the further optimization to technique scheme, described booster is pressurizing cylinder or pressure oil pump.
The technical program utilizes the oil return of the folding mould oil cylinder in die sinking process to promote demoulding oil jar work; a pressure regulator is set between die sinking oil return and demoulding oil-feed and changes flow and pressure; realize a power source and controlled two executive components; both can prevent demoulding oil jar magnetic valve misoperation mold damage, and also can save machine cost, reduce energy consumption.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described further.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of better embodiment of the utility model.
The specific embodiment
As shown in Figure 1, the die sinking of injection machine, demoulding link gear, comprise folding mould oil cylinder 3 and demoulding oil jar 7, the oil-in of the piston-rodless end oil pocket of described folding mould oil cylinder 3 is provided with the first check valve 2, on described the first check valve 2, the oil inlet pipe 1 being connected with oil pump is installed.The oil-out of the piston-rodless end oil pocket of described folding mould oil cylinder 3 is connected with interlock oil pipe 4, on interlock oil pipe 4, is provided with for changing the booster 5 of flow and pressure, and booster 5 can adopt pressurizing cylinder or pressure oil pump.The second check valve 6 is installed in one end of described interlock oil pipe 4, and described the second check valve 6 is arranged on the oil-in of the piston-rodless end oil pocket of described demoulding oil jar 7.The oil-out of the piston-rodless end oil pocket of described demoulding oil jar 7 is provided with flowline 8, and flowline 8 is connected with fuel tank.
Operation principle of the present utility model is as follows:
Hydraulic oil enters the piston-rodless end oil pocket of folding mould oil cylinder 3 from oil inlet pipe 1, and then the piston and the piston rod that promote folding mould oil cylinder 3 move to right, the matched moulds process that this is injection machine.
In die sinking process, what the hydraulic oil in fuel tank entered folding mould oil cylinder 3 has a tailpiece of the piston rod oil pocket, the piston and the piston rod that promote folding mould oil cylinder 3 move to left, while is due to the effect of the first check valve 2, hydraulic oil in the piston-rodless end oil pocket of folding mould oil cylinder 3 enters interlock oil pipe 4, and after booster 5, its oil pressure strengthens, and enters the piston-rodless end oil pocket of demoulding oil jar 7, the piston and the piston rod that promote demoulding oil jar 7 move to right, and carry out demoulding action.
When demoulding oil jar 7 resets, demoulding oil jar 7 have an oil-feed of tailpiece of the piston rod oil pocket, the piston and the piston rod that promote demoulding oil jar 7 move to left, and due to the effect of the second check valve 6, the hydraulic oil in the piston-rodless end oil pocket of demoulding oil jar 7 is got back to fuel tank by flowline 8 simultaneously.
More than describe preferred embodiment of the present utility model in detail.The ordinary skill that should be appreciated that this area just can be made many modifications and variations according to design of the present utility model without creative work.Therefore, all technical staff in the art, all should fall in protection domain of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment according to design of the present utility model.
