Description

technical field [0001] The invention relates to the technical field of casting core removal, in particular to a casting core removal device. Background technique [0002] Sand core casting (especially coated sand) is the most commonly used casting method for castings. This casting method can efficiently cast castings with channels and cavities inside. However, after casting with this casting method, it is necessary to The sand core inside the casting is removed, and the removed sand core usually needs to be recycled to achieve the effect of multiple utilization of resources. [0003] Existing casting core removal technology generally includes two ways of manual sand core removal and mechanical equipment removal of sand core. Among them, the manual removal of the sand core is usually by manually using a hammer, a pick or an electric drill to hit the workpiece and break the sand core, so that the sand core is separated from the inner wall of the casting, and then manually fli...

Problems solved by technology

[0007] However, in the process of removing the sand core of the above-mentioned device, if the casting has only one sand outlet and only one through inner cavity, it only needs one clamping to complete. However, when the casting contains multiple sand outlets and When there are multiple cavity flow channels, the staff need to clamp the casting multiple times according to the position of the sand outlet, which undoubtedly increases the labor load of the staff and reduces the sand removal efficiency of the casting.
