The first sand core placement jig 1 and the second sand core placement jig 2 equipped with the conformal positioning block are placed on the first slide tray 2 and the second slide tray 8 respectively. The first slide tray 2 and the second slide tray 8 are both equipped with a 70mm diameter round pin and a 20mm width key bar as positioning.
