Definitions
- the invention relates to a device for the production of Metal die-cast parts, especially made of non-ferrous metals, with a Hot chamber die casting machine with one in a casting tank trained riser and one in front of a sprue system arranged mouthpiece, as well as with a bleed in front a die-casting mold, the cross section of which is on the respective molten metal is coordinated.
- Hot chamber die casting machines with associated mold construction are known. Non-ferrous metals are used in hot chamber die casting Zinc and magnesium and to a lesser extent lead or shed tin. Metal has the property of cooling quickly. Die casting is therefore carried out to ensure the best casting quality to achieve with high speed and high pressure.
- the mold filling process depends on the size of the part and is minimal Wall thickness between 5ms and 30ms.
- the closing force of hot chamber machines is up to 10000kN.
- the sprue system Empirical values for example with zinc at a maximum gate speed of approx. 50m per second and with magnesium at a maximum of 100m per second. at the high melting temperatures of approx. 650 ° C used Magnesium and approx. 420 ° C for zinc are these non-ferrous metals in the liquid state almost as thin as water.
- the cross-section of the gate surface i.e. the part of the sprue system, which is followed by the separation of the sprue part from the shape, corresponding in its cross section be designed.
- the present invention is based on the object an embodiment of a device of the type mentioned to be provided in the case with a significantly lower proportion of sprue can be worked.
- the invention consists in a Establishment of the type mentioned in that the gate Is part of a hot runner gate system that is a heater which provides channels and nozzles up to the shape.
- This configuration makes it possible to insert the material in the always necessary, sometimes very complex sprue channels keep in a liquid state so that after cooling the metal in the mold does not cool down in the runner located material occurs. This material can be used again with the next shot.
- nozzle tips attached to the nozzles which are sprinkled with a comb or Fan gate system provided and directly on the contour of the part, using the comb or fan gate system forms the gate or immediately in front of it is.
- This configuration has the advantage that the one in the gate cross section of the nozzle tips Molten metal after filling the mold, at least in the semisolids Condition passes because the nozzle tips themselves do not are heated. This material prevents that after after opening the mold metal flows out of the hot runner system or through this back into the mouthpiece, the riser or the pouring can back.
- nozzle tips and Provide nozzles with tapered plug connections which also at the very high temperatures mentioned above of 650 ° C or 420 ° C a sufficient seal through the Ensure that metal is attached to metal.
- the nozzle tips themselves can be attached to heated nozzles be and the nozzles in turn to the heated channels.
- the nozzle tips can on the adapted the shape of the part to be manufactured be trained.
- the nozzle tips can match this shape can be attached laterally or centrally.
- An alternative to preventing the backflow of the liquid Metal in the riser and the pouring can also be achieved in that the mouthpiece on the sprue system adjacent and unheated nozzle tip assigned in which a plug forms after filling the mold, which again the backflow of those in the mouthpiece and riser Can prevent melt to the casting tank.
- This Graft is pushed into the hot runner system on the next shot, where a corresponding receiving space for the graft is provided, in which the plug comes and thereby the further injection of liquid material is not further impeded becomes. The plug melts again in the hot runner system on.
- a check valve is arranged in the riser.
- a check valve can also be arranged in the casting piston, so that the disadvantage that has hitherto occurred in die casting machines is that when the casting piston is withdrawn from the riser no material flows in due to the material occurring in the casting cylinder Vacuum material past the piston rings in the Casting cylinder flows, can be avoided.
- a check valve in the casting piston material can now directly from the casting tank through the casting piston into the Casting cylinders flow.
- the check valves to be used in this case should be with regard to the high occurring Temperatures made of highly heat-resistant metal or ceramic consist.
- Fig. 1 shows the more or less schematically Casting tank 1 of a hot chamber die casting machine, which in the Melt 2 of the metal to be cast, for example magnesium or zinc. This molten metal 2 will held within a crucible 3, the in not shown Way is used in a holding oven.
- the casting container 1 has a casting cylinder 4 with a casting piston 5 on the in unspecified because known Way with a drive connected to its piston rod 6 is provided, the hydraulic or electrical Can be kind.
- the casting cylinder 4 has in its upper region a lateral inflow opening 7 through which the Melt 2 can flow into the interior of the casting cylinder 4, if the piston 5 is in a position above this opening 7 lying position.
- Pouring piston 5 exceeded the filling position and is in mind of the arrow 8 moves downward, the in the casting cylinder 4th and in the riser hole adjoining the casting cylinder 4 9 located melt over the - heated - nozzle 10 the sprue mouthpiece 11 is supplied, which is in the schematic indicated fixed mold half 12 is located.
- the hot runner system 13 now avoids the seizure such considerable cast remains. It is initially closed in Fig. 2 recognize that the sprue mouthpiece 11 from a heating sleeve 17 is surrounded by the connecting line 18 with Energy is supplied.
- the heating sleeve can, like that further to be provided heating sleeves 19 and the heating cartridge 20, which for heating the nozzles 15 or for heating the Channel 14 serve to be supplied with electrical current.
- the 3 now shows that the nozzle 15 in front of the mold cavity 16 provided with a cone 21 and with this in the associated Receiving cone of part 22 of the hot runner system 13 inserted and is kept sealed there.
- the nozzle 23 itself is comb-like at its lower end arranged injection channels 25 provided directly in open the mold cavity 16.
- the cross section of all injection channels 25 must correspond to the gate cross section as a whole, according to those applicable to the hot chamber die casting process Empirical values for the production of a certain Form is necessary. This ensures that the casting speed occurring in these channels 25 permissible maximum speed does not exceed how that was mentioned at the beginning.
- the im Hot runner system 13 existing melt at one temperature can be kept at which they are still in the liquid state located.
- the after the die casting process melt held under pressure in the mold 16 solidifies relatively fast.
- the one in the comb casting of the plurality of channels 25 Melt at least goes into the semi-solid state about.
- the nozzle tip 23 is not heated and it is located in the area of the mold cavity 16.
- This Gate formed by the plurality of channels 25 becomes, when removing the movable mold half 26 of the channel part 27 remaining on the fixed mold half 12 separated so that no frozen sprue residue remains would then have to be melted again.
- nozzle tip 23b which in turn has a cone 21b is attached to the nozzle 15b.
- This nozzle tip 23b is with its sprue channels 25b and 30 centrally on the mold cavity 16b put on and causes the melt centrally pressed directly into the mold cavity 16b becomes. Due to the large number of channels 25b also used here or 30, all - just as with the nozzle tips 23 and 23a of FIGS. 3 to 6 have diameters of approximately 1 mm to 1.5 mm can also create a kind of comb casting, which when opening the mold slightly, both from the nozzle tip and can then be detached from the die-cast part.
- the used non-ferrous metals such as magnesium and zinc in the liquid state, i.e. so at their melting temperatures of about 650 ° C for magnesium and about 420 ° C for zinc, almost like that are as fluid as water. You can therefore easily through the "comb casting" into the corresponding mold cavities in press.
- the mold filling process takes times in the order of magnitude between 5ms and 30ms.
- the one in the form Material then solidifies relatively quickly while the Material in the small holes 25, 25a and 25b of the nozzle tips 23, 23a and 23b passes into the semi-solid phase and thereby the hot runner system even at the end of the die casting process 13 completes. With the next shot this will be material still in the semi-solid phase with in the shape pushed in.
- Fig. 10 shows another possibility relatively simple way of refluxing from the melt to prevent the hot runner gate system 13.
- heated nozzle 10 becomes a mouthpiece body 34 used, which is not heated and therefore a "freezer zone" forms. After each shot is inside this mouthpiece body 34 a cold plug 35 arise, which the Seals through hole of the nozzle 10. Melt in the hot runner system 13 can therefore not through the sprue 11 flow back.
- FIG. 2 shows that the hot runner gate system 13 is in alignment to the through hole 36 of the mouthpiece 10 on the rotor channel 14 has a receiving space 37 (Fig. 2) in which the Graft 35 is caught on the next shot and therefore do not get to the mold cavities through the channel system can. This plug melts in the hot runner system 13 to following shot on.
