Machine and method for forming a moulding core. |
摘要 |
<p>A sand core (66) is moulded between the top and bottom cores box sections (21 and 24) and, after the sections have been separated, the core stands above the lower section (24) on ejection fingers (70). A core removing device (44) is run into the space above the core (66) and carries fingers (60) which are lowered over the core to grip the same for removal of the core by reversal of the movements of the removing device (44). This device also carries beneath the fingers (60) a shaping plate (62) with a shaped aperture corresponding to the desired outline of the core. As the fingers (60) are lowered, the shaping plate is passed over the core and removes moulding flash (80) around its periphery.</p> |
