Abstract
The utility model relates to a lock-shifting oil cylinder of a hot-chamber die casting machine. The lock-shifting oil cylinder comprises a horizontally-installed oil cylinder barrel (1), an oil cylinder barrel front cover (2), an oil cylinder barrel rear cover (3), a piston (4) arranged in the oil cylinder barrel (1), a piston rod (5) connected with the piston (4) and a fixing seat (8) welded on a die casting machine frame (13). The lock-shifting oil cylinder formed by assemblies is installed on a die casting machine tail board away from a smelting furnace and no longer needs cooling water. The oil cylinder is not subjected to heat radiation of the smelting furnace and can work at the normal temperature. Oil leakage caused by the fact that a sealing element is subjected to high temperature for a long period of time is avoided. Operations including replacement of hot work parts and the like are not interfered by the lock-shifting oil cylinder, and collision damage of the piston rod caused by the operations is avoided. Especially, when magnesium alloy is produced, safety accidents caused by the oil leakage or water leakage of the lock-shifting oil cylinder are completely eradicated. The lock-shifting oil cylinder is installed on the tail plate, only a head plate moves in die adjustment, movement resistance is reduced, and the die adjustment is smooth.
Description
Technical field
The utility model relates to hot chamber machine, and the lock that is specifically related to a kind of hot chamber machine moves oil cylinder.
Background technology
Hot chamber machine all to utilize a lock move oil cylinder regulate die holder buckle, from chewing etc., all be installed on the dnockout kettle stand as the one of which.Just be installed in below the dnockout kettle stand owing to have the die casting machine smelting furnace of high temperature, the position of moving oil cylinder with lock is approaching.
This installation method that lock moves oil cylinder causes many problems to occur:
One, its inner oil sealing easy ageing;
Two, oil cylinder is at high temperature worked all the time, needs to cool off oil cylinder with oil cylinder cover one direct cooling water;
Adjacent component such as piston rod are prone to damage when three, changing thermal work parts;
Resistance was big when four, die holder moved;
Be prone to produce security incidents such as blast when five, magnesium alloy is produced.
Summary of the invention
The lock that the utility model discloses a kind of die casting machine moves oil cylinder, is intended to solve existing existing the problems referred to above of die casting machine.
The utility model is that the technical scheme that is adopted that achieves the above object is:
A kind of lock of hot chamber machine moves oil cylinder, it is characterized in that: said lock moves oil cylinder and is installed on the die casting machine tailgate away from smelting furnace, and it comprises with lower member:
The one horizontal cylinder tube of installing;
One cylinder tube protecgulum has a fuel feed hole and a plurality of pull bar installing hole on the said protecgulum, also have a piston rod hole in addition;
One cylinder tube bonnet has an oil outlet and a plurality of pull bar installing hole on the said bonnet, its rear end also has a connecting rod hole in addition;
One places the piston and a piston rod that is attached thereto in the cylinder tube;
And the holder that is welded on the die casting machine frame.
The lock of above-mentioned a kind of hot chamber machine moves oil cylinder; It is characterized in that: said cylinder tube rear end is fixed on the die casting machine frame through the connecting rod that two Connection Blocks and pass the connecting rod hole on the cylinder tube bonnet, and front end then is installed in piston rod on the holder with a connecting seat;
The lock of above-mentioned a kind of hot chamber machine moves oil cylinder, it is characterized in that: said cylinder tube protecgulum and cylinder tube bonnet all adopt square structure, and the two connects each other through the many pull bars that are fixed on tie rod hole and strains at;
The lock of above-mentioned a kind of hot chamber machine moves oil cylinder, it is characterized in that: on the piston rod of said piston rod and holder junction, be enclosed with a piston rod packing ring.
The beneficial effect of the utility model is:
1, lock moves oil cylinder will no longer need cooling water;
2, lock moves oil cylinder away from smelting furnace, and its oil cylinder is avoided the smelting furnace heat radiation, makes oil cylinder learn work under the temperature;
3, lock moves oil cylinder away from smelting furnace, has avoided potted component to receive high temperature for a long time and changes, and causes leakage of oil;
Therefore and the result that damages who produces 4, lock moves the oil cylinder piston bar and no longer hinders operations such as changing thermal work parts, has also avoided piston rod;
5, particularly when producing magnesium alloy, stopped time lock and moved the oil cylinder leakage of oil or the caused security incident of leaking;
6, lock moves oil cylinder and is installed on the tailgate, and an only plate motion has reduced the resistance of motion during mode transfer, makes mode transfer more smooth and easy.

The specific embodiment
As depicted in figs. 1 and 2:
A kind of lock of hot chamber machine moves oil cylinder, it is characterized in that: said lock moves that oil cylinder is installed in away from smelting furnace
On the die casting machine tailgate, and specifically comprise with lower member:
The one horizontal cylinder tube of installing 1;
One cylinder tube protecgulum 2 has a fuel feed hole and four tie rod holes on the protecgulum 2, also have a piston rod hole in addition;
One cylinder tube bonnet 3 has an oil outlet and four tie rod holes on the bonnet 3, also have a connecting rod hole in addition;
One places the piston 4 and a piston rod 5 that is attached thereto in the cylinder tube 1;
And the holder 8 that is welded on the die casting machine frame.
The lock of above-mentioned a kind of hot chamber machine moves oil cylinder; It is characterized in that: said cylinder tube 1 rear end is fixed through Connection Block 10, Connection Block 11 and the connecting rod 12 that passes the connecting rod hole of oil cylinder bonnet 3, and front end is installed in piston rod 5 on the holder 8 with a connecting seat 9 and fixes;
The lock of above-mentioned a kind of hot chamber machine moves oil cylinder, it is characterized in that: said cylinder tube protecgulum 2 all adopts square structure with cylinder tube bonnet 3, and the two connects each other through four pull bars 7 and strains at;
