Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to an automated device for taking out die-casting cores.

[Conventional technology]

In general, products with multiple shapes, such as the surge tank shown in Figures 9 and 10, having an undercut part a, a bottom rib b, a semicircular part c, etc., are cast using only a fixed mold and a movable mold. Since mold cutting is not possible in this case, when casting a product with such a complex shape, a core d is set in advance in a part corresponding to the undercut part a etc. in the cavity before casting. .

Conventionally, the method for taking out the core d is to separate it from the product using a hammer or the like after casting.

[Problem that the invention attempts to solve]

However, since the core must be moved and removed in a complicated manner within the limited space of the die-cast product, the operator must be highly skilled, and since the work is done by hand, there is the problem that work efficiency is extremely low. .

The present invention has been made to solve the above problems, and the object is to provide an automatic core take-out device that can automate the removal of placed cores and greatly improve the productivity of die casting. That is its purpose.
