Your question makes no sense. Rage Extractor triggers on a spell being cast, so it cannot trigger on itself, since it's not on the battlefield yet (it's on the stack). And casting Golem's Heart doesn't trigger it because there's no phyrexian cost. You will gain 1 life, if the Heart is on the battlefield when you cast the Extractor, but that's all. There is no further interaction between those two cards.
I meant if rage extractor were to trigger with another phyrexian cause would the ability trigger golems heart or does golems heart only trigger when an artifact hits the field
The Heart only triggers off of spells being cast, not abilities. The Heart will not trigger if the Extractor's ability triggers.

Scientists have calculated that the chance of anything so patently absurd actually existing are millions to one. But magicians have calculated that million-to-one chances crop up nine times out of ten.
In fact, both cards trigger on a spell being cast. Rage Extractor triggers on a spell with phyrexian mana in its cost, and Golem's Heart triggers on artifact spells. If you cast an artifact with phyrexian mana in its cost (such as a second Rage Extractor, for example), you'll get the effect of both.
Note that the Golem's Heart will also trigger for your opponent's artifact spells.
Golem's Heart
