Abstract
The utility model relates to a combined type omniseal die vacuum box of a pressure die-casting machine. The combined type omniseal die vacuum box comprises a vacuum barrel, elastic inflating sealing rings, a fixed die sealing cover and a movable die sealing cover. Sealing grooves are respectively formed in the two sides of the inner circumference of the vacuum barrel. The elastic inflating sealing rings are arranged in the sealing grooves. A cooling water nozzle is arranged in the vacuum barrel and is connected with a cooling pipe. The fixed die sealing cover is arranged on a fixed die base plate. The movable die sealing cover is arranged on a movable die base plate. The fixed die bottom plate and the movable base plate are respectively arranged on rails of a base of the pressure die-casting machine and can be movably combined or separated. The fixed die base plate and the movable die base plate simultaneously move toward the vacuum barrel and enter the vacuum barrel to form the combined type omniseal die vacuum box of the pressure die-casting machine. The combined type omniseal die vacuum box of the pressure die-casting machine can reduce the vacuum pressure in a vacuum die-casting die mold cavity to 2000 pascals, quickens the mobility of melted metal in the die mold cavity, improves the quality of products, starts a cooling water system to spray water to a fixed die and a movable die after vacuum is released, improves working environments and protects the health of workers.
Description
Technical field
The utility model 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 as 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 " moving housing and fixed shell form the seal chamber cooperatively interacting " of die casting machine, seal chamber connects vacuum power accumulating tank, vacuum power accumulating tank connects vavuum pump, makes " in seal chamber, reaching certain vacuum ".First shortcoming that the structure of above-mentioned " a kind of vacuum pressure casting machine " exists is: because moving housing and fixed shell form the seal chamber cooperatively interacting, rely on traditional seal to implement sealing to seal chamber, 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 generation pore, affect the quality of product, under high temperature action, there is oxidation in the air-flow and the metal that enter in mold cavity, affect the quality of product.Second shortcoming that the structure of above-mentioned " a kind of vacuum pressure casting casting machine " exists is: because moving 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 purpose of this utility model is for two shortcomings of the structure existence of above-mentioned vacuum pressure casting machine, develops a kind of die casting machine Combined full-closed mould vacuum tank.On die casting machine base, track is set, in the bottom of fixed clamping plate and moving clamping plate, rail wheel is set, fixed clamping plate can move combination or separated with moving clamping plate on the track of die casting machine base, makes the installation of dynamic model and cover half with operation is very easy.Between fixed clamping plate and moving clamping plate, vacuum cylinder is set, in vacuum cylinder, all 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, form 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 generation vacuum in mold cavity, the mobility of the metal of acceleration melting in mold cavity, reduce vapour lock and the oxidation of mold cavity, improve the quality of product.
The purpose of this utility model is achieved in that
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.
Vacuum cylinder is the hollow body of cylinder type or rectangle in horizontal direction, and 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.In vacuum cylinder, the both sides in week are respectively equipped with 1 or 1 above seal groove, are provided with elastic inflated sealing ring in seal groove.The air inlet of elastic inflated sealing ring is communicated with gas tube.On die casting machine base, be provided with track, 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 form die casting machine Combined full-closed mould vacuum tank.
The utility model structure is also applicable to injection machine.
Method of operating of the present utility model:
Fixed clamping plate and moving clamping plate move away vacuum cylinder to two ends respectively 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, form 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 generation vacuum in mold cavity, the mobility of the metal of acceleration melting in mold cavity, reduce vapour lock and the oxidation of mold cavity, improve the quality of product.After die casting program completes, discharge the compressed air in elastic inflated sealing ring, vacuum tank is removed vacuum, starts cooling water system cooling to fixed half and moving half trickle.Complete after cooling program, fixed clamping plate and moving clamping plate move away respectively vacuum cylinder outward, take out die-cast product.
The beneficial effect of the utility model contrast prior art is:
1, in vacuum cylinder, all two ends are provided with elastic inflated sealing ring Combined full-closed mould vacuum tank, in the middle of vacuum tank and mould, form vaccum interval, adopt elastic inflated sealing ring to significantly improve the vacuum in mold cavity, vacuum pressure in vacuum die-casting mould die cavity is reduced to below 2000 handkerchiefs, the mobility of the metal of acceleration melting in mold cavity, the quality of raising product;
2, the utility model arranges track on casting casting machine base, bottom at fixed clamping plate and moving clamping plate arranges rail wheel, fixed clamping plate can move combination or separated with moving clamping plate on the track of die casting machine base, makes the installation of dynamic model and cover half with operation is very easy;
