Abstract
The utility model discloses one kind backflow unidirectional stop valve retreating prevention mechanism, including oil cylinder group, hydraulic control one-way valve, three-way connection and high-pressure oil pipe；Hydraulic control one-way valve and three-way connection are connected by conduit respectively in oil cylinder group；Oil-feed interface is provided with the wall of the three-way connection side, enters the hydraulic medium oiler that incoming interface connects die casting machine；Hydraulic control one-way valve side wall is provided with oil out port, and the utility model provides a kind of backflow unidirectional stop valve retreating prevention mechanism, and structure is novel；During work, hydraulic medium in die casting machine enters piston by the oil-feed interface of three-way connection, and piston promotes sliding block to enter in mould, and the residual hydraulic medium in die casting machine is out of high-pressure oil pipe, by in the hydraulic cylinder that is returned in check valve, preventing the hydraulic oil pressure release in hydraulic cylinder from causing retrogressing；The utility model mechanism ensure that sliding block does not produce retrogressing phenomenon in the direction of motion, prevents overlap, gives up the throne and damage part by pressure, so that production division can obtain qualified casting.
Description
Technical field
The utility model is related to the cylinder movement mechanism technology field on die casting；Specifically a kind of backflow unidirectional cutoff
Valve retreating prevention mechanism.
Background technology
Die casting be cast liquid forging a kind of method, a kind of technique completed on special die casting die forging machine,
Its basic craft course is：Molten metal elder generation's low speed or high-speed casting fill type and entered in the die cavity of mould, and mould has the die cavity of activity
Face, it pressurizes with the cooling procedure of molten metal and forged, had both eliminated the shrinkage porosity defect of contraction cavity of blank, and also made the interior tissue of blank
Reach the Broken Crystal of forging state；The comprehensive mechanical performance of blank is significantly improved；But at present, the oil on die casting
Cylinder, when moving to design attitude, because the mould excessive rear piston of type power that rises has retrogressing phenomenon, causes mould overlap, damages core by pressure；
Therefore the mechanism for preventing from moving toward second direction after a kind of cylinder movement is needed.
Utility model content
The purpose of this utility model is to provide a kind of backflow unidirectional stop valve retreating prevention mechanism, to solve above-mentioned background technology
The problem of middle proposition.
To achieve the above object, the utility model provides following technical scheme：
Technical problem to be solved in the utility model is that the mechanism is provided on die cylinder, to solve existing cunning
Block is given up the throne toward the opposite direction of the direction of motion.
One kind backflow unidirectional stop valve retreating prevention mechanism, including oil cylinder group, hydraulic control one-way valve, three-way connection and high-pressure oil pipe；
Hydraulic control one-way valve and three-way connection are connected by conduit respectively in oil cylinder group；Oil-feed is provided with the wall of the three-way connection side to connect
Mouthful, enter the hydraulic medium oiler that incoming interface connects die casting machine；Hydraulic control one-way valve side wall is provided with oil out port, it is described go out
Oily interface connects the hydraulic medium oil-out of die casting machine；High-pressure oil pipe connection is provided between the check valve and three-way connection.
It is used as further program of the utility model：The high-pressure oil pipe is the high pressure resistant oil pipe of metal.
Compared with prior art, the beneficial effects of the utility model are：The utility model provides a kind of backflow unidirectional cutoff
Valve retreating prevention mechanism, structure is novel；During work, the hydraulic medium in die casting machine enters piston by the oil-feed interface of three-way connection,
Piston promotes sliding block to enter in mould, and the residual hydraulic medium in die casting machine is out of high-pressure oil pipe, by being returned in check valve
In the hydraulic cylinder entered, prevent the hydraulic oil pressure release in hydraulic cylinder from causing retrogressing；The utility model mechanism ensure that sliding block exists
The direction of motion does not produce retrogressing phenomenon, prevents overlap, gives up the throne and damage part by pressure, so that production division can obtain qualified casting.
Brief description of the drawings
Fig. 1 is the structural representation of backflow unidirectional stop valve retreating prevention mechanism.
In figure：1- oil cylinders group, 2- hydraulic control one-way valves, 3- three-way connections, 4- high-pressure oil pipes.
Embodiment
The technical scheme of this patent is described in more detail with reference to embodiment.
Referring to Fig. 1, a kind of backflow unidirectional stop valve retreating prevention mechanism, by oil cylinder group 1, hydraulic control one-way valve 2, three-way connection 3
Constituted with high-pressure oil pipe 4；The high-pressure oil pipe 4 is the high pressure resistant oil pipe of metal；Hydraulic control list is connected by conduit respectively in oil cylinder group 1
To valve 2 and three-way connection 3；Oil-feed interface is provided with the side wall of three-way connection 3, the hydraulic pressure for entering incoming interface connection die casting machine is situated between
Matter oiler；The side wall of hydraulic control one-way valve 2 is provided with oil out port, and the hydraulic medium of the oil out port connection die casting machine goes out
Hydraulic fluid port；High-pressure oil pipe 4 is provided between the check valve 2 and three-way connection 3 to connect.
Operation principle of the present utility model is：The utility model provides a kind of backflow unidirectional stop valve retreating prevention mechanism, structure
It is novel；During work, the hydraulic medium in die casting machine enters piston by the oil-feed interface of three-way connection, and piston promotes sliding block to enter
In mould, the residual hydraulic medium in die casting machine is out of high-pressure oil pipe, by the oil cylinder group that is returned in check valve, preventing
Hydraulic oil pressure release in hydraulic cylinder causes to retreat.
The better embodiment to this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
, can also be on the premise of this patent objective not be departed from formula, the knowledge that one skilled in the relevant art possesses
Make a variety of changes.
