Description
Technical field
The present invention relates to the vacuum seal die device of die casting machine, particularly a kind of die casting machine Combined full-closed mould vacuum tank.
Background technology
Evacuated die-casting process device has been widely used in die cast metal field.Vacuum in vacuum die-casting mould die cavity is higher, and the metal of melting is better in mold cavity internal mobility, and the pore rank in metal casting is lower.The vacuum seal die device of current die casting machine, name disclosed in the patent of invention of Chinese patent publication No. CN101791686A is called the structure of " a kind of vacuum pressure casting machine ", in " dynamic housing and fixed shell form the seal chamber cooperatively interacted " of die casting machine, seal chamber connects vacuum power accumulating tank, vacuum power accumulating tank connects vavuum pump, makes " reaching certain vacuum in seal chamber ".First shortcoming that the structure of above-mentioned " a kind of vacuum pressure casting machine " exists is: rely on traditional seal to implement sealing to seal chamber because dynamic housing and fixed shell form the seal chamber cooperatively interacted, along with improving constantly of vacuum in seal chamber, extraneous air can enter in seal chamber from the slight void of the traditional seal of seal chamber, produce the metal of melting in the direct Impact mould die cavity of air-flow at a high speed, make the metal of melting in mold cavity produce turbulent flow and generate pore, affect the quality of product, enter air-flow in mold cavity and metal, under high temperature action, oxidation occurs, affect the quality of product.Second shortcoming that the structure of above-mentioned " a kind of vacuum pressure casting casting machine " exists is: because dynamic housing and fixed shell are separately fixed on moving clamping plate and fixed clamping plate, so affect installation and the operation of dynamic model and cover half.
Summary of the invention
The object of the invention is two shortcomings existed for the structure of above-mentioned vacuum pressure casting machine, develop a kind of die casting machine Combined full-closed mould vacuum tank.Die casting machine base arranges track, rail wheel is set in the bottom of fixed clamping plate and moving clamping plate, fixed clamping plate and moving clamping plate can move on the track of die casting machine base combine or is separated, make dynamic model and cover half installation and operation is very easy.Between fixed clamping plate and moving clamping plate, arrange vacuum cylinder, vacuum cylinder inner circumferential two ends are provided with elastic inflated sealing ring.Fixed clamping plate and moving clamping plate move into vacuum cylinder to columnar vacuum cylinder simultaneously, composition die casting machine Combined full-closed mould vacuum tank.After fixed half and moving half locking, to the inflation of elastic inflated sealing ring, after sealed vacuum case, vacuum tank vacuumizes, and makes to produce vacuum in mold cavity, accelerates the mobility of metal in mold cavity of melting, reduce vapour lock and the oxidation of mold cavity, improve the quality of product.
The object of the present invention is achieved like this:
Die casting machine Combined full-closed mould vacuum tank comprises vacuum cylinder, elastic inflated sealing ring, cover half seal cover and dynamic model seal cover.
The hollow body of vacuum cylinder cylinder type or rectangle in horizontal direction, vacuum cylinder is fixed on the top of die casting machine base.Vacuum cylinder is provided with vacuum-pumping tube, gas tube, cooling tube, drainpipe and vacuum meter.Vacuum cylinder inside is provided with cooling water nozzle, and cooling water nozzle is connected with cooling tube.Vacuum-pumping tube is connected with pumped vacuum systems, and gas tube is connected with compressed air system, and cooling tube is connected with cooling water system.The both sides of vacuum cylinder inner circumferential are respectively equipped with the seal groove of more than 1 or 1, are provided with elastic inflated sealing ring in seal groove.The air inlet of elastic inflated sealing ring is communicated with gas tube.Die casting machine base is provided with track, and the bottom of fixed clamping plate and moving clamping plate is respectively equipped with rail wheel, and fixed clamping plate and moving clamping plate are separately positioned on the track of die casting machine base.Fixed clamping plate is provided with cover half seal cover, and moving clamping plate is provided with dynamic model seal cover.Vacuum cylinder, elastic inflated sealing ring, cover half seal cover and dynamic model seal cover composition die casting machine Combined full-closed mould vacuum tank.
Structure of the present invention is also applicable to injection machine.
Method of operating of the present invention:
Fixed clamping plate and moving clamping plate move away vacuum cylinder respectively to two ends on the track of die casting machine base, install fixed half and moving half respectively on fixed clamping plate and moving clamping plate.Fixed clamping plate and moving clamping plate move to centre simultaneously, and cover half seal cover and dynamic model seal cover enter vacuum cylinder from two ends, composition die casting machine Combined full-closed mould vacuum tank.After fixed half and moving half locking, to the inflation of elastic inflated sealing ring, after sealed vacuum case, vacuum tank vacuumizes, and makes to produce vacuum in mold cavity, accelerates the mobility of metal in mold cavity of melting, reduce vapour lock and the oxidation of mold cavity, improve the quality of product.After die casting procedures completes, discharge the compressed air in elastic inflated sealing ring, vacuum removed by vacuum tank, starts cooling water system and cools to fixed half and moving half trickle.After completing cooling program, fixed clamping plate and moving clamping plate move away vacuum cylinder respectively to outer end, take out die-cast product.
The beneficial effect that the present invention contrasts prior art is:
1, vacuum cylinder inner circumferential two ends are provided with elastic inflated sealing ring Combined full-closed mould vacuum tank, vaccum interval is formed in the middle of vacuum tank and mould, employing elastic inflated sealing ring significantly improves the vacuum in mold cavity, the vacuum pressure in vacuum die-casting mould die cavity is made to be reduced to below 2000 handkerchiefs, accelerate the mobility of metal in mold cavity of melting, improve the quality of product;
2, the present invention arranges track on casting casting machine base, in the bottom of fixed clamping plate and moving clamping plate, rail wheel is set, fixed clamping plate and moving clamping plate can move on the track of die casting machine base combine or is separated, make dynamic model and cover half installation and operation is very easy;
