Description
Technical field
The utility model relates to a kind of check valve more particularly to a kind of horizontal type cold-chamber die casting pressurization control check valves.
Background technique
Cold-chamber die casting machine is the Casting Equipment for die cast metals such as aluminium alloy, fine aluminium, magnesium alloy, copper alloys at present,
Existing cold-chamber die casting machine all uses no floating piston arrangement, and die casting enters solidification stages after filling type, in solidification rank
Section will apply the pressure increased to casting, improve the consistency, intensity, air-tightness of casting；There is pressurization in cold-chamber die casting machine
Mechanism, the low-pressure area of pressurization and higher-pressure region are isolated with a check valve, and the flow of check valve directly affects injection speed, single
It directly affects and builds the pressure time to the reversed shut-in time of valve, injection speed is to measure cold-chamber die casting machine injection performance with the pressure time is built
Important parameter, existing check valve flow is small, and the reversed shut-in time is long, thus influence cold-chamber die casting machine performance.
Summary of the invention
For disadvantage mentioned above, the purpose of this utility model is to provide a kind of injection speed for improving cold-chamber die casting machine and contractings
The horizontal type cold-chamber die casting pressurization control check valve for building the pressure time of short cold-chamber die casting machine.
The technology contents of the utility model are a kind of horizontal type cold-chamber die casting pressurization control check valve, it is characterized in that it is wrapped
Include valve deck, guide rod, valve pocket, pressurization spool, inner spring and outer spring；Valve pocket one end is fixedly connected with valve deck, the valve pocket other end
Port inner wall is equipped with a sealing bulge loop, is equipped with several through-holes in sleeve side wall；It is equipped with a connection pedestal in guide rod, guide rod is logical
It crosses on the valve deck that connection pedestal is connected in valve pocket, a bullet is equipped on the connection base end face of connection pedestal and guide rod junction
Spring groove is equipped with a spring boss in the other end of guide rod；It is equipped with a guiding groove in pressurization spool one end, it is another in pressurization spool
One end is equipped with a sealing ring；Pressurization spool is sleeved on guide rod by being oriented to groove, and pressurization spool can move on guide rod；Interior bullet
Spring is sleeved on the spring boss of the guide rod in guiding groove；Outer spring is sleeved on the outside of pressurization spool, the setting of outer spring one end
In spring groove, the outer spring other end is withstood on the inner sidewall of sealing ring, and lateral wall and the sealing convex ring for sealing of sealing ring connect
Touching.
The utility model compared with prior art possessed by advantage are as follows: the utility model is mounted in by that will be pressurized valve core housing
On guide rod and being arranged for dual spring presses the time to improve the injection speed of cold-chamber die casting machine and shorten building for cold-chamber die casting machine, thus
Greatly improve the performance of cold-chamber die casting machine.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the stereoscopic appearance figure of the utility model.
Specific embodiment
As depicted in figs. 1 and 2, a kind of horizontal type cold-chamber die casting pressurization control check valve, it is characterized in that it include valve deck 1,
Guide rod 2, valve pocket 3, pressurization spool 4, inner spring 5 and outer spring 6；3 one end of valve pocket is fixedly connected with valve deck 1,3 other end of valve pocket
Port inner wall is equipped with a sealing bulge loop 3.1, is equipped with several through-holes 3.1 in 3 side wall of valve pocket；A linker is equipped in 2 one end of guide rod
Seat 2.1, guide rod 2 are connected on the valve deck 1 in valve pocket 3 by connecting pedestal 2.1, in connection pedestal 2.1 and 2 junction of guide rod
It connects 2.1 end face of pedestal and is equipped with a spring groove 2.1.1, be equipped with a spring boss 2.2 in the other end of guide rod 2；It is being pressurized
4 one end of spool is equipped with a guiding groove 4.1, is equipped with a sealing ring 4.2 in pressurization 4 other end of spool；Pressurization spool 4 passes through guiding
Groove 4.1 is sleeved on guide rod 2, and pressurization spool 4 can move on guide rod 2；Inner spring 5 is sleeved on leading in guiding groove 4.1
On the spring boss 2.2 of bar 2；Outer spring 6 is sleeved on 4 outside of pressurization spool, and 6 one end of outer spring is arranged in spring groove 2.1.1
In, 6 other end of outer spring is withstood on the inner sidewall of sealing ring 4.2, and lateral wall and the sealing sealing of bulge loop 3.1 of sealing ring 4.2 connect
Touching.
The working principle of the utility model is that the utility model is installed to cold-chamber die casting machine pressurization low-pressure area and pressurization is high
The junction of pressure area, the pressurised oil for being pressurized low-pressure area push pressurization spool 4, make to be pressurized spool 4 in guide rod 2 to 1 one sidesway of valve deck
Dynamic, the sealing bulge loop 3.1 of the sealing ring 4.2 and valve pocket 3 that are pressurized spool 4 generates gap, and pressurised oil is just from the gap into valve pocket 3
It is interior, then enter supercharging high-pressure area from through-hole 3.1, when pressure reaches setting value, the pressurised oil for being pressurized low-pressure area stops pushing
Be pressurized spool 4, while being pressurized spool 4 and will quickly be pushed back by inner spring 5 and outer spring 6, make the lateral wall of sealing ring 4.2 with it is close
It is in sealing contact to seal bulge loop 3.1, is left so that pressurization low-pressure area be made to separate with supercharging high-pressure.
