Description
Technical field
The present invention relates to a kind of safety door linkage unit more particularly to a kind of hydraulic peaces of magnesium alloy semi-solid
Air cock interlock.
Background technique
Currently, semi-solid magnesium alloy product mainly uses injection (mo(u)lding) machine mating mold to produce.
Semi-solid magnesium alloy injection moulding has the unrivaled advantage of other casting methods, and such as (magnesium alloy melts for energy conservation
Temperature is low: general magnesium alloy cast needs for magnesium alloy to be heated to 650-680 DEG C, and injection moulding magnesium alloy need to only be heated to 580-
600 DEG C), (do not need protective gas: general magnesium alloy cast is needed using SF6 etc. after melting magnesium alloy to environment nocuousness for environmental protection
Protective gas prevent magnesium alloy from aoxidizing and burning, the magnesium alloy for being injection moulded thawing do not contact with air), safety (general magnesium
Although alloy casting has used protective gas after melting magnesium alloy, the still risk with the presence of spontaneous combustion and explosion, injection moulding is melted
The magnesium alloy of change is in the closed container not contacted with air, so as to avoid the risk of spontaneous combustion and explosion) etc..
Injection (mo(u)lding) machine can produce semi-solid magnesium alloy product, but the Clamping System of existing injection (mo(u)lding) machine is producing
It is possible to malfunction in the process, thus the danger of user of service and peripheral equipment to injection (mo(u)lding) machine.
Summary of the invention
In order to overcome drawbacks described above, the present invention provides a kind of magnesium alloy semi-solid hydraulic safe door is chain
Device guarantees the safety of work freak piece and equipment.
The present invention is to solve technical solution used by its technical problem: a kind of magnesium alloy semi-solid
Hydraulic safe door interlock, including safety door, folding mould oil cylinder, open mold control valve, open mold oil return cylinder and open mold supply
Oil cylinder, the open mold oil return cylinder and open mold are connected to the oil inlet of the folding mould oil cylinder for oil cylinder by open mold control valve
And oil outlet, the safety door side are equipped with motorised control valve, connection oil of the open mold for oil cylinder and open mold control valve
Road is equipped with open mold delivery valve, and the motorised control valve controls the synchronous opening and closing of the open mold delivery valve；The peace
When air cock is closed, the motorised control valve and open mold delivery valve are in synchronous opening state；When the safety door is opened, the peace
The collision block that air cock touches the motorised control valve makes the motorised control valve and open mold delivery valve synchronizing close.
The beneficial effects of the present invention are: the hydraulic safe door interlock is by increasing motorised control valve and open mold fuel feeding
Valve, safety door and open mold control valve is chain, and safety door, which must save fully closed condition, to provide control for die sinking oil cylinder
Otherwise liquefaction will just be molded and be disconnected with control oil, to reach personnel and the unapproachable effect of other equipment in molding safety zone
Fruit substantially increases the safety of personnel and equipment in clamping process, effective protection magnesium alloy semi solid state equipment user of service and week
The safety of edge equipment.
Detailed description of the invention
Fig. 1 is the safe door closure state structural schematic diagram of structure of the invention；
Fig. 2 is structure of the invention emergency gate opening state structural schematic diagram.
In conjunction with attached drawing, make the following instructions:
1 --- safety door；2 --- motorised control valve；
3 --- open mold delivery valve；4 --- open mold control valve；
5 --- folding mould oil cylinder；51 --- oil inlet；
52 --- oil outlet；6 --- open mold oil return cylinder；
7 --- open mold is for oil cylinder.
Specific embodiment
Below in conjunction with attached drawing, elaborate to a preferred embodiment of the invention.But protection scope of the present invention is not
Be limited to following embodiments, i.e., in every case with simple equivalence changes made by scope of the present invention patent and description with repair
Decorations, all still belong within the invention patent covering scope.
Refering to fig. 1,2, it is a kind of magnesium alloy semi-solid hydraulic safe door interlock of the present invention,
Including safety door 1, folding mould oil cylinder 5, open mold control valve 4, open mold oil return cylinder 6 and open mold for oil cylinder 7, which is returned
Oil cylinder 6 and open mold are connected to the oil inlet 51 and oil outlet of the folding mould oil cylinder 5 for oil cylinder 7 by open mold control valve 4
52,1 side of safety door is equipped with motorised control valve 2, connection oil circuit of the open mold for oil cylinder 5 and open mold control valve 4
It is equipped with open mold delivery valve 3, the motorised control valve 2 controls the synchronous opening and closing of the open mold delivery valve 3；The peace
When air cock is closed, the motorised control valve 2 and open mold delivery valve 3 are in synchronous opening state；It, should when the safety door is opened
The collision block that safety door touches the motorised control valve 2 makes 3 synchronizing close of the motorised control valve 2 and open mold delivery valve.
The working principle of the hydraulic safe door interlock is as follows:
When safety door 1 is closed, refering to fig. 1, motorised control valve 2 is in synchronous opening state with open mold delivery valve 3, this
When the oil inlet 51 and oil outlet 52 and open mold oil return cylinder 6 and open mold of folding mould oil cylinder 5 are controlled by open mold control valve 4
For the link relation of oil cylinder 7, to realize the disengaging oil control of folding mould oil cylinder 5, the i.e. control of working condition.
When safety door 1 is opened, referring to Fig.2, safety door 1 collides the collision block on motorised control valve 2, the motorised control valve 2
Commutation closure, while controlling 3 synchronizing close of open mold delivery valve, 3 closed amputation open mold of open mold delivery valve for oil cylinder 7 with open
Mold control valve 4 fuel feeding route, i.e., delivery valve close, can not fuel feeding, open mold control valve 4 is unable to control folding moulding oil at this time
Cylinder 5 is run, so that it is guaranteed that the safety under 1 opening state of safety door, effective protection magnesium alloy semi solid state equipment user of service and
The safety of other peripheral equipments.
It can be seen that the hydraulic safe door interlock, which passes through, increases motorised control valve and open mold delivery valve, it will be safe
Door and open mold control valve are chain, and safety door, which must save fully closed condition, to provide control oil for die sinking oil cylinder, otherwise
It will just mold and be disconnected with control oil, to reach personnel and the unapproachable effect of other equipment in molding safety zone, be mentioned significantly
The peace of the safety of personnel and equipment in high clamping process, effective protection magnesium alloy semi solid state equipment user of service and peripheral equipment
Entirely.
