Definitions
- the present invention relates to a die casting method and diecasting system for use in a hot chamber die casting die casting system comprising a hot chamber die casting machine having a casting vessel and a melt distribution manifold that uniformly distributes the melt from a machine die to uniformly heated die casting nozzles.
- a hot chamber die casting machine having a casting vessel and a melt distribution manifold that uniformly distributes the melt from a machine die to uniformly heated die casting nozzles.
- at least one check valve is arranged between a sprue area of the die casting nozzles and the casting container, wherein the non-return valve prevents the melt from flowing back from the sprue area in the direction of the casting container.
- the sprue as a by-product of casting which solidifies in conventional die-casting processes in the channels between the die-cast nozzle and the casting mold and ultimately connects the cast parts after removal from the mold in an undesirable manner, entails additional material expenditure, which is generally between 40% and 100%. the weight of the casting is. Even if the sprue for material recycling is remelted, this is associated with energy and quality losses due to the formation of slag and oxide fractions. Angeless die casting avoids these disadvantages.
- the reflux into the crucible can be prevented by valves, but also in a particularly advantageous manner by a plug of solidified melt, which closes the gate in the die-casting nozzle.
- the object of this problem is to provide a die-cast nozzle system for use in a die-cast hot-melt chamber for molten metal, which allows easy temperature control and simple construction.
- a diecasting nozzle system for use in a hot chamber system for die casting of metallic melt, comprising a hot chamber die casting machine with a casting container and a melt distributor, which distributes the melt evenly from a machine nozzle to heated die casting nozzles, wherein at least one check valve between a sprue area of the die casting nozzles and the pouring vessel, wherein the check valve prevents backflow of the melt away from the gate area toward the pouring vessel.
- These are primarily low-viscosity melts, v. a. from non-ferrous metals, to the melting temperature of aluminum. According to the prior art, however, the liquid melt can be withdrawn from an upper nozzle and at the same time undesirably run out of a lower nozzle by the shear force.
- the check valve is arranged in each case between the sprue area of at least the upper die casting nozzle or, in the case of several, of the upper die cast nozzles and a last branch in the melt distributor to each of the diecast nozzles.
- melt channels in the melt distributor form communicating tubes and melt thereby flows back from a die-casting nozzle arranged in the upper region of the melt distributor and, accordingly, melt flows out of a die-cast nozzle arranged in the lower region of the melt distributor by the action of gravity could.
- this prevents the check valve in the region between the sprue area of the die casting nozzle and the last branch in the melt distributor at least to the diecasting nozzle, for example in the upper diecasting nozzle itself.
- the die cast nozzles can be heated from the inside and / or from the outside in the region of a nozzle body and include sprue areas which have at least one heat conductivity of the melt to be processed itself and / or are separately heatable. It is particularly advantageous if the heating takes place from the outside and the heat is forwarded into the sprue areas, so that an internal heating can be dispensed with. It is thus provided that the die-cast nozzle is externally heated, wherein the external heating can also be designed as a printed heater (thick-film heating). The external heating can be formed by a heat-shrinkable brass or stainless steel sleeve containing the heater.
- the die casting nozzle can thus be indirectly heated by the heating heat flows from the heated nozzle body in the runner.
- the highest possible thermal conductivity, but not smaller than that of the melt itself eg Zn> 100 W / mK, Mg by> 60, Al by 235 W / mK
- suitable choice of material for example a molybdenum alloy, tungsten or a thermally conductive Ceramic, possible.
- the die-cast nozzle is internally heated, which is also included in the invention.
- a thermal protection device provided in the sprue area of each diecasting nozzle, which reduces a heat outflow from the sprue area in the direction of the casting mold.
- a thermal insulation in the sprue area is in question, as the insulating ring of a surrounding the sprue area material with low thermal conductivity, such.
- titanium alloys or ceramic as an insulating air, gas or vacuum layer within the runner and / or as a constant air layer between the body of the die-casting nozzle and the mold, which forms a uniform or circumferential air gap as an insulating space is executed. The insulation serves to avoid heat losses and to minimize the heat output.
- the gate region of the mold has an insulation which reduces heat dissipation into the mold.
- the insulation is part of the nozzle and is not formed by the mold or the melt, as is the case with plastic injection molding.
- it is alternatively or additionally provided for thermal insulation, the To heat the sprue area of the mold, so to speak, as an "active insulation" to reduce the heat flow from the sprue area by these measures, leaving the melt in the runner liquid and must not be remelted after the demolition of the casting.
- a further embodiment of a counter-heater is provided in order to reduce the heat flow.
- This counterheater is preferably designed as a separately heatable segment arranged around the sprue and / or as a separately heatable sprue area.
- a counterheating has proven to be particularly advantageous, which uses a highly dynamic C0 2 - cycle process for their operation.
- a melt channel which has a tear-off edge in the area of the die casting die area which is designed to form a cross-section-reducing predetermined breaking point in the melt solidified in the casting area, at which the article breaks off when the gate area is lifted off ,
- the tear-off edge is arranged on one side either peripherally on the outside of a central conductor or on the inside of the melt ladder, in each case at the bottom, towards the sprue area lying end. Also, a two-sided arrangement is provided.
- a temperature sensor is arranged in the sprue area. This temperature sensor generates readings that can be used to control the nozzle heater.
- a controlled nozzle heater allows for optimal process control, increases productivity and product quality, and reduces wear on the die-cast nozzle.
- the temperature sensor in the front area of the nozzle, the region near the sprue, thus supports optimized operation of the heating system by using its measured values to control the nozzle heating.
- non-return valve is arranged in the nozzle channel of the die-casting nozzle itself.
- a suitable non-return valve has a, preferably in a cage, freely movable ball which cooperates with a valve seat.
- the nozzle has a certain gate geometry.
- a ring ensures a clean demolition, cross or star shapes are also provided.
- the center conductor forming the ring receives a longitudinal bore which extends through the gate area. This allows a better flow of the melt with equally good demolition.
- the quality of the tear is further improved by a tear-off edge, which can be arranged inside and / or outside in the sprue area.
- the die-cast nozzle thus has a gate geometry adapted to the respective requirements.
- the sprue only cools when the heat flows into the casting, the product, and cools the sprue area, as long as the casting remains connected to the sprue area.
- the sprue area does not cool too much, however, because due to thermal insulation in the sprue area of the nozzle, only little heat flows directly into the mold. As a result, the heat flow is channeled essentially via the liquid or solidified melt.
- the die casting process comprises the process steps:
- Such a method does not require the formation of a sealing melt plug in the sprue area, so that the clock frequency during die casting can be increased and the thermal cycling of the diecasting nozzle can be reduced. In addition, the safety against exiting melt is increased.
