Definitions

  • the invention relates to a die-casting mold, comprising a first mold plate that is hot during operation and has at least one die-casting nozzle with a pouring point for a melt, and a second mold plate that forms a cold side, with the first and second mold plates being in a closed state a mold cavity is formed in the die-casting mold, in which a molded part can be produced from solidified melt introduced into the mold cavity via at least one melt channel and the at least one die-casting nozzle, the die-casting mold further comprising a demolding system for demolding the molded part from the die-casting mold, the demolding system having an ejector arrangement , a drive device and a power transmission device connected to the drive device and the ejector arrangement.
  • the power transmission device serves to transmit drive forces to the ejector arrangement.
  • the invention also relates to a hot chamber system for the die casting of molten metal in a hot chamber process, in which melt is held in a liquid state at a pouring point of a die casting nozzle, which opens into a die casting mold, the hot chamber system comprising a hot chamber die casting machine with a casting container and a machine nozzle which the melt reaches the die-casting nozzle via a melt channel, it being possible to form a plug of solidified melt, interrupting a melt flow, at a pouring point of the die-casting nozzle.
  • the invention also relates to a method for die-casting metal that is in the form of a melt and to the use of a die-casting mold.
  • the area of the die-casting nozzle from which the melt emerges during the casting process and where the sprue, to which one or more molded parts are connected to the lip, forms is referred to as the spout point.
  • the spout point In the case of sprue-free die casting, in which only one part is formed in front of the die casting nozzle, this is located directly on the part and is not separated. This side of the die, the hot mold plate, is therefore also known as the sprue side.
  • the demolding system also referred to as an ejector or ejector unit, is used to demould a cast part from a mold cavity.
  • the demolding system essentially consists of the ejector pressure plate and the ejector holding plate as well as a number of generally round ejectors, usually ejector pins or sleeves, that depend on the contour of the molded part.
  • the ejectors held in place by a collar on the ejector holding plate are now pushed forward by means of a drive device, usually an ejector bolt, and the ejector plate in order to eject the molded part from the die casting mold or its mold cavity.
  • the demolding system can also include more complex functions such as inclined ejectors, contour ejectors or flat ejectors.
  • the demolding system is usually protected by limit switches or by return pressure bolts, which force the ejector package back when the mold closes if it has not been retracted beforehand in the event of an error, in order to prevent errors in the program sequence and the associated damage to the valuable mold sections.
  • the ejector pressure plate is always designed to be stronger than the ejector retaining plate, because it is used for power transmission and transmits the ejection force from the drive device, usually an ejector rod driven from outside the die, to the ejector.
  • Die-cast metal components are often used when the end products in which they are installed are to embody a high-quality appearance. Particular value is placed on the visual finish and the feel of the visible surfaces. Such items are then usually finished with various chemical surface processes. Numerous galvanic and polymer-based coatings are available for this purpose. However, all of these procedures are special Requirements for the casting quality of the cast items, specifically for the surfaces produced. Numerous applications from the areas of furniture, sanitary ware or vehicle interiors can be cited as examples.
  • Both the porosity of the molded parts, also known as castings, and inclusions on the surface have a very negative effect on the subsequent surface.
  • markings on the surface such as those B. caused by ejectors, not desired. So far, the surface formed by the first mold plate has the marking of the sprue, and the surface formed by the second mold plate has the markings of the ejectors. As a result, a side with a perfect undisturbed surface cannot be formed.
  • die-casting methods are known from the prior art that make this possible and describe a sprue-free die-cast.
  • Die-casting methods and die-casting nozzle systems are known for use in a hot-chamber system for the die-casting of molten metal, in which a plug of solidified melt interrupting a melt flow can be formed directly on the sprue, on the surface of the subsequent molded part. Only the use of the aforementioned methods enables direct connection to the molded part and, in addition to material and energy savings, a significant increase in casting quality.
  • the direct connection eliminates the sprue as a by-product of casting, which solidifies in the channels between the die-casting nozzle and the die-casting mold in conventional die-casting processes, which ultimately connects the cast parts with one another after demolding and which has to be removed in a time-consuming process.
  • impressions of the nozzles, of the now minimized sprue area occur on the surface of the molded part on the hot side of the die casting mold.
  • markings appear on the opposite side of the molded part, formed by the cold side of the mold with the ejectors located there.
  • a high-quality side cannot be produced by the casting process alone.
  • a die-casting mold comprising a first mold plate, which is hot during operation and has at least one die-casting nozzle with a pouring point for a melt, and a second mold plate, which forms a cold side.
  • a mold cavity is formed between the first and second mold plates, in which a molded part made of solidified material is introduced into the mold cavity via at least one melt channel and the at least one die-casting nozzle melt can be produced.
  • the die-casting mold also includes a demolding system for removing the molded part from the die-casting mold.
  • the demolding system includes an ejector assembly, preferably comprising ejector pins or an ejector sleeve, each held in an ejector holding plate.
  • an ejector assembly preferably comprising ejector pins or an ejector sleeve, each held in an ejector holding plate.
  • force is transmitted to the ejector arrangement by an ejector pressure plate.
  • the demolding system therefore has an ejector arrangement, a drive device and a power transmission device connected to the drive device and the ejector arrangement.
  • the demolding system is arranged in such a way, in particular with a peripheral drive, outside the area of the at least one melt channel and the at least one die-casting nozzle, and in particular the drive device has such a temperature resistance that it can be arranged in the first mold plate.
  • the first mold plate heats up due to the incoming melt or has to reach a sufficiently high temperature have, so that the melt can enter the mold cavity at the required temperature.
  • the temperature of the first mold plate depends on the melt temperature.
  • the temperature resistance of the drive device must therefore be guaranteed, for example up to 300 °C.
  • the drive device of the demolding system is arranged peripherally in the first mold plate and at least two linear drives are arranged outside the area of the at least one melt channel, the at least one die-casting nozzle and its pouring point.
  • the linear drives are designed as hydraulic drives, each comprising a hydraulic cylinder on both sides of the region of the melt channel and the die-casting nozzles.
  • pneumatic or electric linear drives, spindle drives or other suitable embodiments can also be used.
  • the required temperature resistance of up to 300 °C also applies to the other drive systems intended for use.
  • the temperature specification is an example, ultimately the respective melt temperature determines the requirements.
  • the ejector arrangement comprises ejector pins that act discretely and/or is designed as a sleeve ejector in the form of a ring around the ejection point of the die-casting nozzle.
  • Both the ejector pins and the case ejector can be equipped with an inert gas connection, an inert gas line inside and an inert gas outlet.
  • At least one protective gas outlet e.g. B. an inert gas nozzle, proven to release an inert gas into the mold cavity during demoulding.
  • the main advantage is realized in particular when using flammable melts, namely magnesium. This can oxidize and burn at high speed, which can occur during demolding when residues of liquid magnesium escape from the die-casting nozzle.
  • the pouring point of the die-casting nozzle is closed by the solidified melt and the heat dissipation via the molded part means that the sprue does not melt.
  • the state at the pouring point, behind which the liquid melt is held in the nozzle for the next casting process becomes unstable.
  • the sprue closed by a slug of melt (the rest of the sprue that does not adhere to the molded part) or the pouring point of the die-casting nozzle can tear open and liquid melt can escape. Then oxidation occurs between the melt and the oxygen from the ambient air. In the case of critical melts, especially magnesium, this takes place in a violently exothermic manner and triggers a fire.
  • oxide can still form, especially in the area of the pouring point of the die-casting nozzle, and damage the mold or the die-casting nozzle.
  • protective gas By using protective gas during ejection, a fire and damage to the die and die can be prevented at the potential point of origin.
  • the protective gas flows directly out of the ejector arrangement, since this is located directly in the mold cavity and is significantly involved in ejecting the molded part.
  • a further away e.g. A protective gas outlet arranged next to the mold cavity, for example, would be less effective, since the protective gas would first have to reach the mold cavity and would also have to be made available in larger quantities.
  • the use of the ejector arrangement to transport the protective gas inside to the protective gas outlet and the targeted application offers an elegant solution.
  • the at least one protective gas outlet is therefore particularly preferably arranged in the ejector arrangement which, when the molded part is ejected, directly enters the mold cavity, here in particular at a pouring point of the nozzle, the starting point of such oxidation.
  • Particular advantages result from a further developed arrangement, in which the at least one protective gas outlet in the ejector wall, the wall of the ejector, for example on the inside of the wall of a sleeve ejector pointing to the pouring point of the die-casting nozzle, is arranged.
  • the shielding gas is guided directly to the discharge point of the nozzle, where there is a particular risk of oxidation or the outbreak of a fire when using critical melts, and is also kept in the area by the case ejector like an apron. This leads to high effectiveness and low gas consumption.
  • the protective gas outlet is arranged in an area which only emerges during ejection from the first mold plate, so that the protective gas outlet is only released during ejection.
  • the inert gas outlet remains covered, closed and protected during the casting process. In this way, it cannot cause any additional disruption to the surface.
  • a plurality of protective gas outlets are preferably arranged over the circumference of the wall of the ejector pins or of the sleeve ejector, in order to be able to release protective gas in a sufficient quantity.
  • any gas that can prevent oxidation and for this purpose keeps the oxygen in the ambient air away can be considered as a protective gas.
  • nitrogen is used as the protective gas, since this gas is readily available and, as the main component of the ambient air, is harmless and requires no further safety precautions.
  • the demolding system is accessible via the mold cavity side of the first mold plate when the die is open.
  • the object of the invention is also achieved by a hot-chamber system for die-casting metallic melts in the hot-chamber process, in which the melt is held in a liquid state at a pouring point of a die-casting nozzle that opens into a die-casting mold.
  • the hot chamber system includes a hot chamber die casting machine with a pouring vessel and a machine nozzle through which the melt enters a die. At the pouring point of the die-casting nozzle, a plug that interrupts a melt flow can be formed from solidified melt.
  • the hot chamber system also includes at least one melt channel, which merges into a heating zone and a nozzle tip, which preferably form the die-casting nozzle or are part of it, which is adjoined by a sprue region of the die-casting mold.
  • the die casting mold embodied as a die casting mold with a demolding system as previously described.
  • a protective gas flows into the mold cavity and to the pouring point of the pressure die-casting nozzle, from which the oxygen in the air is kept away.
  • This is particularly advantageous for melts that have an inherent risk of severe oxidation and ignition. This applies in particular to magnesium, the processing of which is associated with a high risk of fire.
  • the protective gas flows out of the ejector arrangement, since this is located directly in the mold cavity and essentially at the ejection point of the molded part is involved. It has also proven to be advantageous if nitrogen is used as the protective gas, since this gas is harmless as the main component of the ambient air and therefore requires no further safety precautions.
  • the object is also achieved through the use of a die-casting mold, as described above with the demolding system, designed as a die-casting mold for die-casting metallic melts in the hot-chamber process, in which the melt is held in a liquid state at a pouring point of the die-casting nozzle.
  • both the surface quality and the integrity of the visible surface can be guaranteed unaffected by nozzles or ejectors.
  • Elaborate processing steps such as grinding the visible surfaces or the sprue edges are no longer required.
  • Surface defects which are a major problem in every foundry, are greatly reduced.
  • profitability increases.
  • a molded part can be produced with the aid of the present invention that does not require any post-processing.
  • the side of the molded part opposite the sprue can also be produced without the surface being adversely affected by markings caused by the ejectors. Instead, these markings are moved to the opposite side, where the molded part is already affected by the sprue. This achieves a completely unimpaired surface that meets the highest requirements and can be used or finished without post-processing.

Only the first mold plate 11 of the die 10 is shown.
  • the second mold plate adjoins in the area of the mold cavity side 15 when the die casting mold 10 is closed. Before the casting process, it is moved up to the first mold plate 11 so that complete mold cavities 14 are formed as cavities, and moved away to open the die casting mold 10 to remove the molded part 16 .
  • the second mold plate only has cavities and no other built-in components or functional elements, which is why the second mold plate was not shown for a better overview.
  • Each of the mold cavities 14 can be reached by means of a demolding system 20, specifically ejector pins 28 on the left-hand side or an ejector sleeve 30 on the right-hand side of the illustration, for demoulding the molded part 16 from the first mold plate 11.

  • the ejector pins 28 are also guided in the guide plate.
  • the hydraulic cylinders 22 are arranged outside the area in which the machine nozzle 2 attaches, the melt channels 4 run and the die-casting nozzle 6 is arranged. This deviates from the conventional central drive of the demolding system known from the prior art via a central ejector bolt. It has been shown that the entire demolding system 20 can be arranged in the first mold plate 11 due to the decentralized drive device 21 divided among several hydraulic cylinders 22 for generating the demolding force, combined with the advantages mentioned in the description.
  • the hydraulic cylinder 22 Since high temperatures of several 100°C occur in the first mold plate 11, particularly during die casting, due to the metal melts used, the hydraulic cylinder 22 is designed to be correspondingly temperature-stable and maintains the temperatures in the first mold plate 11, which are determined by the respective melt temperature and therefore different requirements put, stood.
