This application claims a priority date of 24 Jun. 2015, based on prior filed German patent application No. 10 2015 110 133.5, the entire contents of the aforesaid German patent application being incorporated herein by reference.
The invention concerns a casting assembly comprising a casting mold enclosing at least two casting cavities for casting a cast part each; the casting mold can be opened in a first release direction and in at least one second release direction different from the first release direction.
Casting assemblies employing a casting mold which is to be opened in a first release direction and in at least one second release direction that is different from the first release direction are known. Such casting molds comprise in particular:
The object of the invention is to improve for a casting assembly, comprising a casting mold that encloses at least two casting cavities for casting a cast part each, the destruction-free release action with the goal of casting even relatively complex casting parts.
As a solution to this object, a casting assembly of the aforementioned kind in accordance with the invention is characterized in that the lateral parts are arranged to be movable in the second release direction, in that the first mold parts are supported each on guides which are formed on the first base plate and extend in the second release direction, and in that the first mold parts are arranged to be movable along the guides.
In this casting assembly, the lateral parts are arranged so as to be moveable in the second release direction; furthermore, the first mold parts are supported on guides, respectively, which are formed on the first base plate and which extend in the second release direction, wherein the first mold parts are arranged to be movable along the guides.
With this casting assembly, a high degree of releasability on all sides is achieved so that even cast parts of a complex configuration can be cast without having to destroy individual mold parts for the purpose of release after casting. The casting assembly is suitable therefore in a special way for larger series production without the requirement of having to newly manufacture individual mold parts, for example, of solidified molding sand.
Casting can be performed with a three-plate tool as well as with an injection piston and a shot chamber as well as with a two-plate mold tool, i.e., with two parallel and simultaneously operating injection pistons and two shot chambers.
In one configuration of the casting assembly, it is proposed that the guides are oriented in the same direction and preferably aligned relative to each other.
In another embodiment, stops on the first base plate are proposed which delimit the movability of the first mold parts in the direction toward each other.
In a further embodiment, it is proposed that the first mold parts each comprise a mold section, which determines the configuration of the respective casting cavity, and a support section wherein only the support section is supported on the guide.
According to further embodiment of the casting assembly, the guide extends to a point behind the fifth mold part wherein a portion of the support section is located between the guide and the fifth mold part.
Further advantages and details result from the following description of two embodiments. In the drawings, the casting mold and of the individual release steps of the employed release process.
The casting assembly according to
After the two cast parts have cooled down sufficiently, the casting mold 2 is opened stepwise and in this way the cast parts are released, which is done in individual steps. In
A component of the casting mold is a first base plate 3 which is extending transverse to the first release direction D1 and against which the first mold parts 11A, 11B determining the casting cavities 1A, 1B are supported in release direction D1. A second base plate 4 serves herein as an intermediate plate of the casting assembly and is supported against the stationary plate 8.
The second mold parts 12A, 12B determining the configuration of the casting cavities 1A, 1B are supported in the release direction D1 against the second base plate 4 (intermediate plate).
Lateral parts 6, 7 which are arranged between the base plates 3, 4 are also a component of the casting mold 2. In this context, a third mold part 13 which determines the configuration of the first casting cavity 1A is supported on the first lateral part 6. A fourth mold part 14 determining the configuration of the second casting cavity 1B is supported on the second lateral part 7.
The lateral parts 6, 7 are movably guided on the first base plate 3 in the second release direction D2 in order to be able to open, after solidification of the melt, the casting mold in lateral direction, i.e., in the direction of the second release direction D2. Mold parts 13 or 14 determining the shape of the casting are fastened to the lateral parts 6, 7.
A central component of the casting assembly is a fifth mold part 15 determining the shape of both casting cavities 1A, 1B. The fifth mold part 15 is attached to the first base plate 3 such that it is located between the two casting cavities 1A, 1B and that it determines the shape of both of the casting cavities 1A, 1B.
The lateral parts 6, 7 with the mold parts 13, 14 are movably guided in the second release direction D2 along the first base plate 3, which is apparent when comparing the release step according to
The first mold parts 11A, 11B are supported each on guides 31A, 31B which are formed on the first base plate 3 and which extend transversely to the direction of the first release direction D1. Along these guides 31A, 31B the first mold parts 11A, 11B are therefore movable in longitudinal direction, as is apparent when comparing
Preferably, the left guide 31A is arranged oriented in the same direction and aligned with the right guide 31B. Stops 35A, 35B on the lower base plate 3 delimit the movability of the first mold parts 11A, 11B in a direction toward each other.
The first mold parts 11A, 11B are comprised each of a mold section 33 which also determines the configuration of the respective casting cavity 1A, 1B and of a support section 32. Only the support section 32 is supported so as to be slidable on the respective guide 31A, 31B. The mold section 33 on the other hand determines the mold space of the casting cavity.
In particular the release step according to

Finally,
While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
