Definitions
- the invention relates to a casting apparatus according to the preamble of claim 1 and a die-casting method.
- Casting devices for use in die casting and vacuum die casting processes as well as the corresponding methods have been known for some time.
- vacuum die casting a negative pressure or vacuum in the mold cavity of the mold, as well as in the casting chamber, after the casting chamber filled with casting material and the casting piston is moved past the filling opening of the casting chamber, generates.
- Vakuumtikguss compiler be used for the production of castings from metals and metal alloys, in particular from alloys of the metals Al, Mg, Zn and Cu.
- the advantage of vacuum die casting is that the reduced influence of air and gases in the casting material results in a higher quality of the castings. This applies in particular to castings made of aluminum or an aluminum alloy, which in a later process step may also be subjected to a heat treatment and / or welded.
- the vacuum is generated via a vent valve attached to the mold or casting chamber.
- the casting mold Only after the casting chamber has been filled with casting material and the casting piston in a first process step has exceeded the filling opening of the casting chamber and thus the connection to the outside atmosphere has been interrupted, the casting mold can be brought to negative pressure.
- a disadvantage of this procedure is that the method of the casting piston for closing the filling opening of the casting chamber is a comparatively lengthy process and the process time remaining after the filling opening has been exceeded is generally insufficient to sufficiently evacuate the casting chamber.
- the negative pressure to be achieved is further degraded by the narrow cross-sections of the vent valve.
- the method described in DE 10 2004 057 324 A1 provides that after the casting material has been introduced into the casting chamber and the casting chamber has been closed by means of a hood, the casting chamber is evacuated. By this procedure, it is possible to circumvent the tedious first process step of closing the filling opening of the casting chamber by means of the casting piston. Subsequent to the generation of the negative pressure or the vacuum, the casting piston can spend the casting material in the casting mold at a speed that is increased from the beginning, thereby reducing the process time of the actual die-casting.
- a disadvantage of the hood for closing the filling opening of the casting chamber described in DE 10 2004 057 324 A1 is that in order to be able to close the filling opening with the hood, first the feed has to be removed from the filling opening in an upstream process step.
- the present invention is therefore based on the object to eliminate the problems mentioned in generating a negative pressure or vacuum in a casting chamber and in particular to accelerate the cycle time in vacuum die casting and thus to increase the production capacity.
- Another object of the invention is to improve the tightness of a vacuum pressure casting apparatus such that a higher Un- tertik or vacuum in the casting chamber and consequently in the rest of the system is adjustable.
- the casting device according to the invention which is particularly suitable for a die-casting method, preferably for a vacuum die-casting method, and a casting chamber with a filling opening, a casting piston movable in the casting chamber, which is connected or movable in its rear space via a casting piston rod with a casting drive, and a Feed through which the casting material can be filled through the filling opening into the casting chamber comprises, is characterized in that the casting chamber is at least partially disposed in a rotatably mounted sleeve.
- the filling opening of the casting chamber wearable sleeve is achieved that casting material which is dropped during the filling process on the outer wall of the casting, sheared off from this and the filling of the casting chamber can be largely sealed tightly against the atmosphere.
- the sleeve has an opening which can be positioned at least partially over the filling opening of the casting chamber by a rotation of the sleeve.
- the casting chamber is designed to be round in cross-section at least in this area.
- the opening of the sleeve is such that it largely corresponds to the shape and size of the filling opening of the casting chamber. It may be expedient if the opening of the sleeve can be positioned as far as possible in a filling position above the filling opening of the casting chamber. In this position, it is possible to spend or fill in the casting chamber via the inlet, in particular via a runner, casting material.
- predetermined areas of the sleeve and / or the outer shell of the casting chamber are designed such that they ensure a most extensive tightness between the sleeve and the casting chamber around the filling opening of the casting chamber, so as to set a negative pressure within the Improve casting chamber.
- the thermal expansion behavior of the casting chamber and / or sleeve can be exploited.
- the sleeve is rotatable about the longitudinal axis of the casting chamber by means of a rotary device.
- a pneumatically or hydraulically driven rotary device speaks the producible force with such a drive.
- the force that moves the sleeve is advantageously selected to be so great that a secure shearing off of casting material possibly dropped onto the outer wall of the casting chamber is ensured. It may be expedient if the sleeve and / or the inlet are designed such that they are in operative connection with each other. This reduces the cycle time.
- a method of the sleeve may preferably simultaneously effect a method of feed. This reduces the cycle time.
- the operative connection is such that upon rotation of the sleeve, both the sleeve and inlet from one and / or in the filling position are movable, preferably such that the inlet at least partially mechanically when turning the sleeve from the Opening or filling opening can be raised or lowered into the opening or filling opening.
- the sleeve and / or the inlet can advantageously be formed at a suitable location in the manner of an inclined plane, so that sleeve and inlet at least partially slide on each other.
- the sleeve has a suction opening.
- the evacuation of the casting chamber via the filling opening of the casting chamber has the advantage that for the evacuation lines with a much larger diameter, as was the case in the prior art, can be used.
- the use of lines for the evacuation of the casting chamber with the largest possible cross-section allows a time-saving evacuation of the casting chamber.
- suction opening is arranged on the sleeve such that it can be positioned at least partially over the filling opening of the casting chamber by a rotation of the sleeve.
- the suction opening is arranged on the sleeve, that the suction opening is in the casting position of the sleeve over the filling opening of the casting chamber, it is possible the suction automatically with the method of the sleeve from a filling position into the casting position at least partially over the filling opening of the casting chamber to position. Consequently, two method steps, namely the closing of the casting chamber and the positioning of a suction opening over the filling opening of the casting chamber can be realized in only one method step. Such a summary of two process steps to one makes it possible to shorten the overall process in time.
- the sleeve has a lifting element.
- An inventive lifting element makes it possible to remove the inlet, via which the casting material is introduced into the casting chamber, after the casting material has been introduced into the casting chamber from the filling opening of the casting chamber such that the sleeve can be moved from the filling position into the casting position.
- An inventive lifting element may also make it possible to spend the sleeve from the filling position into the casting position in such a way that the inlet, via which the casting material is brought into the casting chamber, is removed from the filling opening of the casting chamber after the casting material has been introduced into the casting chamber.
- the lifting element according to the invention is arranged on the outer wall of the sleeve, it is possible to connect the inlet by means of the lifting element with the sleeve, that by the rotation of the sleeve about the longitudinal axis of the casting chamber of the inlet simultaneously with the rotation of the sleeve from the filling opening Casting chamber is removable.
- the casting piston rod is at least partially disposed in a largely annular closure element, which is mounted displaceably along the longitudinal axis of the casting chamber.
- a largely annular closure element which is mounted displaceably along the longitudinal axis of the casting chamber.
- An extremely significant leak is in this case the annular gap between the inner wall of the casting chamber and the outer shell of the casting piston.
- gases may enter the casting chamber from the back of the casting piston during the process of evacuating the casting chamber. These penetrating gases can lead to a proper foaming of the casting material in the casting chamber and thus produce a gas porosity in the casting, which minimize or even preclude a heat treatment and the weldability of the casting.
- the closure element can be designed such that it tightly seals the annular gap between the inner wall of the casting chamber and the outer shell of the casting piston and does not impair the function of the casting piston or of the casting piston rod.
- the largely annular closure element can be arranged by means of a pusher, in particular a pneumatic or hydraulically driven pusher on the back of the casting chamber.
