High pressure die casting parts

The dies are designed so that the finished casting will slide off the cover half of the die and stay in the ejector half as the dies are opened. This assures that the casting will be ejected every cycle because the ejector half contains the ejector pins to push the casting out of that die half. The ejector pins are driven by an ejector pin plate, which accurately drives all of the pins at the same time and with the same force, so that the casting is not damaged. The ejector pin plate also retracts the pins after ejecting the casting to prepare for the next shot. There must be enough ejector pins to keep the overall force on each pin low, because the casting is still hot and can be damaged by excessive force. The pins still leave a mark, so they must be located in places where these marks will not hamper the casting's purpose.

Pattern and Casting

Pattern will be made first and done inspected before casting.

Cast pieces are presented in the foundry, for inspection of dimensions and hardness after sandblasting and machining but before conservation and painting. Deviations are sanctioned as follows for example:

	GS30Mn5
surface + volume	DIN1690 class 4	DIN1690 class 4
shrinkage	DIN1690 class 5	DIN1690 class 4

Hardness inspection
