Description

  • The present invention relates to an apparatus and a method for manufacturing a casting with at least one fluid-carrying channel for cooling an internal combustion engine.
  • From the German utility model DE 9315991 U1 It is known that for the production of cavities, such as fluid-carrying channels, sand cores are usually required in castings. It is often necessary to assemble several sand cores into a so-called core package. In this case, the individual cores during assembly or after completion of the assembly process until after insertion into the mold must be held together non-positively.
  • In a two-part insert core of conventional design, the upper core must be bonded to hold down with the lower core or the upper core is held down by the outer mold or an oil core. Thus, while the upper core can be reliably held in position, however, a considerable additional effort in the form of core bearings or additional core plug is necessary.
  • Against this background, it is an object of the present invention to provide an improved apparatus and an improved method for manufacturing a casting with at least one fluid-carrying channel for cooling an internal combustion engine, which allow a simple and secure attachment of the cores.
  • This object is achieved by a device having the features of patent claim 1 and by a method having the features of patent claim 8.

The device has a first, second and third core of a temperature-resistant, removable from the finished casting material. The first and second core may be components of a two-piece water jacket, while the third core may be an outlet channel. The first core is arranged on a base plate. The second core is inserted in an opening of the first core. The third core is joined to the first core, wherein a joint of the third core with the first core fixes the third core in the transverse and vertical directions of the first core. Specifically, the fixation of the third core in the high direction of the first core ensures that the third core is securely held in position during a casting process, preferably sand casting the casting to be manufactured. The invention can be used for both sand and gravity casting.
  • It is preferably provided that the joint of the third core is formed with the first core such that a connecting portion of the third core can be inserted into a guide portion of the first core. The provision of the insertable in the guide portion of the first core connecting portion of the third core allows easy mounting of the cores. In addition, the cores can be securely fastened together and have a positive connection.
  • According to an advantageous development of the invention, it is provided that the joint connection of the third core with the first core is designed as a sliding guide, in particular as a dovetail guide. The provision of the sliding guide enables easy insertion of the connecting portion of the third core into the guide portion of the first core. In addition, the sliding guide may be formed with a predetermined resistance or a predetermined sliding friction.
  • According to a further preferred embodiment, it is provided that the third core can be bonded to a depth stop of the first core. This provides, in addition to the provision of the guide portion, a further attachment possibility of the third core to the first core.

Thus, the third core is connected to the first core such that the third core is fixed in all movement axes. The provision of the guide or the guide portion of the first core for inserting the connecting portion of the third core allows the fixing of the third core in two axes of movement, in particular the transverse and vertical direction of the first core. The provision of the glued-on depth stop or a given sliding friction of the sliding guide additionally fixes the third core in the third movement axis, in particular in the longitudinal direction of the first core. Alternatively, fixation of the third core may also be provided by providing a trunnion connection of the third core with, for example, an oil core.
  • According to a further preferred embodiment, it is provided that the guide portion of the first core and the connecting portion of the third core is arranged at a predetermined angle, preferably between 5 ° and 45 °, in particular preferably between 10 ° and 30 ° to the horizontal. By providing a Inclination of the first core in the region of the guide portion and, accordingly, insertion of the connecting portion of the third core along the inclination of the first core can also be ensured that the third core is fixed along an insertion direction, that is, in the longitudinal direction of the first core.
  • Preferably, it is further provided that the first core is designed as a lower shell, the second core as an outlet channel core and the third core as an upper shell. The cores, which are preferably formed as sand cores, can be removed after the casting process.
  • The invention further provides a method for manufacturing a casting with at least one fluid-carrying channel for cooling an internal combustion engine. The method comprises producing a first, second and third core from a temperature-resistant, removable from the finished casting material. The method further comprises placing the first core on a base plate, inserting the second core into an opening of the first core, and joining the third core to the first core, wherein a joint of the third core to the first core forms the third core Transverse and vertical direction of the first core fixed. The method further includes casting the casting with a liquid material and removing the first, second, and third cores from the casting. Specifically, the fixation of the third core in the high direction of the first core ensures that the third core is securely held in position during a casting process, preferably sand casting or gravity casting of the casting to be manufactured.
  • It is preferably provided that a connecting portion of the third core is inserted into a guide portion of the first core. The provision of the insertable in the guide portion of the first core connecting portion of the third core allows easy mounting of the cores. In addition, the cores can be securely fastened together and have a positive connection.
