Definitions
- the invention relates to a device for producing at least one metallic component by injecting flowable metallic material into at least one cavity of a multi-part mold, in particular for casting magnesium or magnesium
- Magnesium alloys in the thixotropic state comprising a conveyor for the flowable metallic material, at least one downstream of the conveyor downstream nozzle and the mold with the at least one cavity, wherein the
- Conveyor connects a distributor unit with a plurality of nozzles, via which the flowable metallic material can be injected under pressure into the at least one cavity in order to fill the at least one or more cavities simultaneously via individual nozzles.
- the invention relates to a method for casting at least one
- magnesium and magnesium-based alloys ie those containing predominantly magnesium, have attracted the attention. Magnesium is significantly lighter than aluminum, which means that components made of magnesium or magnesium-based alloys can potentially achieve significantly higher weight savings. In addition, sufficient mechanical properties are also given for many areas.
- Magnesium and magnesium alloys can be as well as aluminum and
- magnesium and magnesium alloys can be die cast, with flowable metallic material injected under high pressure into a mold.
- die casting it is disadvantageous that components can only be cast with specific dimensions. The production of thin components with wall thicknesses of, for example, 1 mm is currently hardly possible in die casting.
- Another disadvantage of die casting is the limited flow path during manufacture. The longer the flow path, the sooner it comes locally to premature
- Thixomolding is a technology that was developed in the 80's of the last century. Magnesium is used in this technology
- Temperature range of the solid-liquid transition processed In the case of alloys, in the area of the phase diagram between the solidus lines and the liquidus line, ie in the semi-solid state is worked. In these temperature ranges, fine crystallites are present in the surrounding melt during processing.
- Such flowable material is easy to inject into molds, can become thin wall thickness components of about 1 mm and leads above all to components with high material homogeneity and thus ultimately good material behavior in use.
- barrel which accommodate a snail in a coat of steel.
- Metallic granules are fed through a filler neck, which is then brought to the desired temperature in the barrel and homogenized.
- the barrel is followed by a nozzle, through which the screw is injected by axial displacement.
- the nozzle is held in a first part of a mold, which part of the mold during the entire cycle from injection to component removal and the
- a second part of the mold is designed to be movable and is pressed to create a component to the first part of the mold with a closing pressure.
- one or more cavities are provided, in which the one or more components are molded by injecting the flowable metallic material in the thixotropic state. After injecting and cooling the mold, the second part is moved back, so that a removal of the product created is possible. After applying a release agent of the second part of the mold is started again or
- a sprue is provided. This branches from the point of attachment to different areas of the component to be created. This can ensure that the component is molded as quickly as possible in a single cavity and thus a cycle time is kept low. If several cavities are provided for the production of several identical components in a single operation, a sprue is imperative because the flowable material must move from the point of approach equally fast to several cavities same impression.
- waste always accumulates.
- the component or components must be separated from that material which solidifies in the area of the sprue.
- the material must flow along the gate, resulting in longer flow paths, which in turn
- Conveyor is supplied via a distributor unit a plurality of nozzles.
- magnesium and magnesium alloys in the thixotropic state are extremely difficult. This may be due to the fact that a shrinkage of magnesium during solidification is about 10% particularly large, but at the same time a full filling of possibly more cavities is to be achieved, high pressures are applied, the processing temperatures are much higher and at the desired full cavity filling the Nevertheless, the process must be conducted in such a temperature-sensitive manner that no material escapes from the nozzles when the mold is open, which could lead to burnup.
- the previous solutions may consist of a distributor unit with a plurality of nozzles, wherein distributor arms with at least largely identical sections lead to individual nozzles.
- a corresponding device is disclosed in US 2007/0199673 A1.
- devices of this type do not prove to be operable for mass production with cycle times of less than 40 seconds in continuous operation.
- the object of the invention is to provide a device of the type mentioned, with a multiple shooting over several nozzles with high process reliability is possible.
- Another objective is to specify a method suitable for this purpose.
- the object is achieved according to the invention when, in a device of the type mentioned above, the channels of the distributor unit are formed free of corners at a right angle.
- a design of a distributor unit according to the prior art which has right angles in individual sections, can be the starting point for a lack of process reliability. Due to the right angles, the flowable metallic material has to be strongly deflected under the given high pressures of several hundred bars, which results in high pressure peaks and, moreover, makes it difficult to convey the flowable metallic material.
- the distributor unit does not have any corners enclosing a right angle in the region from a branching point of the channels to the nozzles.
- the mentioned pressure peaks which preclude a homogeneous flow of material, are avoided.
- Blunt Wnkel can possibly be present in the channels.
- the conveyor or the barrel is spared.
- the distributor unit is designed without corners. This means that the material from a branching point within the
- Distributor unit or a connection point to the conveyor or the barrel up to an outlet has no corner around which the pourable metallic material is to be passed. It is particularly preferred for the reasons mentioned that the
- Distributor unit has rectilinear sections, which lead from a branch point to the nozzles.
- the branch point is positioned on an end face or within the manifold unit and is charged with material via one end of the barrel.
- the material thus supplied is distributed in the individual sections of the distributor unit and ultimately reaches the nozzles, via which injection can take place. It proves to be particularly advantageous if the channels of the distributor unit branch off from the branching point at an angle of at most 50 °, preferably at most 45 °, in particular 20 ° to 40 °.
- the corresponding Wnkel refers to an axis of the conveyor, usually a horizontal axis of a barrel.
- this angle should be on the one hand a maximum of 50 °, preferably a maximum of 45 °.
- a first part of the mold for a given component size is to be formed longer, the smaller the angle is, since with a smaller angle, the spread is reduced. In this respect, it is favorable if a lower threshold for the angle of 20 ° is not exceeded.
- the distribution unit can basically have any number of channels. A minimum represent two channels. It is preferred, however, that the distributor unit has at least three channels.
- the distributor unit is integrated in a first part of the mold. At least one heating element is provided around the distributor unit in order to be able to heat the distributor unit. It is understood that the distributor unit with the heating element can be further surrounded by a thermal insulation in order to be able to optimally set and maintain a temperature in the distributor unit.
- a heating device For each individual nozzle a heating device is provided with advantage.
- the temperature can be set on or in this, which can prove to be a great advantage during a cycle. For this can
- a controller may be provided for the heaters, which variably controls a temperature at or in the nozzles depending on the status of a cycle.
- a temperature at a nozzle can be kept high during injection, but lowered during the subsequent component cooling and removal and then increased again for the next cycle for producing a component.
- the individual heaters for the nozzles are preferably designed as Wderstandsphasetec, which also allow good control in addition to high performance.
- the individual nozzles are preferably made of a steel, in particular a
- Hot work steel formed to withstand the sometimes high operating temperatures of 500 ° C to 800 ° C permanently.
- the heaters are preferred to the Soldered nozzles.
- the nozzles can have depressions on the outside, in which the heaters are soldered and run in a spiral shape.
- the further aim is achieved if in a method of the type mentioned, the flowable metallic material is guided by a branch point of the distributor unit without deflection to the nozzles.
- An advantage achieved by means of a method according to the invention is to be seen in particular in the fact that, when supplying the flowable metallic material to several individual nozzles, pressure peaks and thus ultimately uncontrollable
- the method is therefore particularly suitable when using a device according to the invention in order to produce large components, possibly also with low wall thickness, while filling a cavity from several points. The same applies if several cavities are filled at the same time via the feed through the nozzles at several points in order to produce a plurality of components.
- the flowable metallic material is branched out from the branching point along rectilinear sections of the distributor unit to the nozzles.
- a favorable flow of material can be achieved, in particular, even if the flowable metallic material is guided branching off from the branch point to the nozzles at an angle of at most 50 °, preferably at most 45 °, in particular 20 ° to 40 °.
- the preferred procedure is that after opening the mold and removing the component or components, a heating power is set at the nozzles so that the plug softens without entry of flowable metallic material into the at least one cavity.
- the stopper broken off at one end by removal of the component is already softened when the mold is still open. A safety risk is not given, because the material does not escape in the pressureless state, even if the solid plug has converted to a softened thin pellicle.
- the plugs in the nozzles are required per se, as explained above, it is preferable to reduce the heating power at the nozzles when the component is allowed to solidify, so that a temperature for plug formation in the nozzles is undershot.

- a device 1 which is designed for a thixomolding of components 2 made of magnesium or a magnesium alloy.
- the device 1 comprises a container in which the material 3 to be processed is kept in stock in granular form. Material 3 is conveyed out of the container into a filler neck via a suction conveyor or another conveying element. About the filler neck, the material 3 enters a conveyor 6 and a barrel, which is provided with a screw with a corresponding drive. The barrel is heated by a suitable
- the nozzle 7 is integrated in a first part 11 of a mold 5.
- a second part 12 of the mold lies opposite the first part 9 of the mold 5 and is horizontally displaceable, so that the mold 5 can be opened, for example, to remove components 2 produced by means of a robot arm.
- FIG. 2 shows a distributor unit 8 which is used in a device 1 according to the invention.
- the distributor unit 8 has a plurality of channels 10 which extend away from a branching point 15 in the distributor unit 8.
- FIG. 2 shows a cross-section of a distributor unit 8 which has a total of four channels 10.
- the channels 10 are formed in sections 9 which are straight.
- the sections 9 can also be bent or executed in another form, as long as corners are avoided, to which flowable metallic Material 3 is difficult or diverted under construction of local pressure peaks, especially in the barrel.
- the distributor unit 8 is installed in the first part 1 1 of the mold 5 and connects at an inlet to the conveyor 6 and the barrel.
- the barrel is pressed in the connection area only to the distribution unit 8.
- the contact surfaces are surrounded by a steel ring cooled by compressed air.
- the sections 9 with the straight channels 10 close to a central feed 16, which is an axial extension along a preferably horizontal axis of the conveyor 6 and the barrel, preferably from the branching point 15 at the same angle ⁇ .
- An angle ⁇ should be between 20 ° and 50 °, preferably 20 ° and 40 °. This results in a gentle flow of
- a nozzle 7 is shown in more detail in FIG.
- the nozzle 7 adjoins a channel 10 of a section 9.
- the nozzle 7 may be permanently attached to the portion 9 or integrally formed therewith. It is also possible that the nozzle is releasably secured to the section 9, for example by a screw connection. This allows the nozzle 7 to be replaced if necessary.
- the nozzle 7 is surrounded on the outside by a heating device 13.
- the heater 13 is designed as a resistance heater. In this case, a heating coil extends along the nozzle 7 around this spiral around. For a good heat transfer and thus a rapid adjustability of the temperature at or in the nozzle 7, the heater 13 is preferably materially connected to the nozzle 7, in particular by soldering.
- a resistance heater is provided in the embodiment, an inductively or differently operating heater may be provided.
- an end region 7 from which ultimately the flowable metallic material 3 exits the nozzle 7 at the point of attachment into a cavity 4, the nozzle 7 is partially tapered. Due to the taper can after solidification of the or of the components 2 and opening the mold 5, the actual casting easily in the field of Graft 14 are stopped, with a part of a plug 14 in the nozzle 7 remains.
- FIG. 4 shows a cavity 4 with an attachment point and a sprue 17.
- a cross with the flowable metallic material 3 has to be filled from the point of attachment to the cavity 4 before the cavity 4 is reached.
- this waste can be recycled, which is expensive.
- longer distances are covered, which must be taken into account in the process.
- the closing pressures for the mold 5 or its first part 11 and its second part 12 are higher because the projected cross-sectional area is greater.
- FIG. 5 schematically shows injection molding with a distributor unit according to FIG. 2. Via four sections 9 with channels 10, the cavity 4 can be filled simultaneously with the entry of flowable material 3 at each of the attachment points.
- a dynamic temperature control at the nozzles 7 is expedient. This is explained in more detail with reference to FIGS. 6 and 7.
- Fig. 6 first, the operations during a (build) cycle are shown. When the mold is closed, the material 3 is injected via the barrel into the downstream nozzle 7 into one or more cavities 4 which are present in the second part 12 of the mold 5. If the cavities 4 are completely filled, the component is cooled.
- a cycle begins with the injection of material 4.
- a cycle as shown in FIG. 6, is common in thixomolding processes.
- the nozzles 7 of the device 1 are subjected to a temperature program which, without extending the cycle time, leads to lower pressure peaks in the conveyor 6 or the barrel and thus significantly increases its service life.
- the variable temperature control on or in a nozzle 7 is in Fig. 7 for a Creation cycle shown.
- the nozzle 7 When injecting into the closed mold, the nozzle 7 is subjected to maximum heating power so that the material 3 can flow freely through the nozzle 7. This corresponds to the state A.
- the heating power can be reduced in a first section of the nozzle 7, which is closer to a gate point, as indicated by a changed hatching in the Heating device 13 is shown. This corresponds to the state B.
- the plug 14 may in principle be formed in further, but possibly lowered heating of the nozzle 7.
- the plug 14 breaks off in the region of the nozzle 7, but remains substantially intact. This corresponds to state C.
- the mold 5 is still open, but the heater 13 can already operate at higher power to soften the plug 14. This corresponds to the state D.
- the mold 5 is closed again, can be driven with the heater 13 at full power, so that the plug 14 ideally completely melts.
- the nozzle 7 is completely free, so that pressure peaks in the conveyor 6 or the barrel are eliminated or at least reduced.
- the targeted softening and subsequent melting of the plug 14 can be carried out within the usual time for a creation cycle of less than 40 seconds.
