[0002] At present, automobile engine cylinder head products are relatively complex, and the interior is formed by sand cores. There are many sand cores. When casting the cylinder head, the sand cores need to be placed inside the outer mold. Under normal circumstances, for products with this structure, the sand cores cannot be removed from the slider mechanism and the slider side cannot be chamfered with R angles, so the sand cores cannot be removed from the mold, and the upper mold may be penetrated.

[0003] On the one hand, the R angle is not chamfered, and in special cases, chamfering is required. The R angle can be repaired manually or by an automatic robot. Manual repairs may be inconsistent or missed, and the cost of robots is high, so the R angle is basically not chamfered. For this reason, a slider mechanism is proposed on the slider of the cylinder head sand core mold. Utility Model Content
