How can we explain the mold and die?

THEN JEWELLERY 3 D PRINT I WILL DO LIQUDE MOLD.AND GET REDAY TO WAX PULL IT IS VERY FAST WORK AT TIME .... IN JEWELLRY INDUSTRY 

to explain the mold we can say that it consists of two separate parts, one as fixed part and the other as the moving part in which are mating together on the press ( injection molding machine ) and then receive the injected melted material in the cavity formed by the mold two parts and maintain this material for specific time until the material reaches the solid phase via cooling environment and then ejecting the product in solid form.

on other hand for the die forming, in this operation we can use hydraulic or eccentric presses to exchange the form of sheet metal from its original form to another by using reciprocated press or hydraulic press to deep drawing forms or perforated forms on cold state        

Due to the Aspect ratio, things may change it names. Like pipe and tube, axle and spindle & so one. Same for the die and mold relation.

Mold refers to the tool used for converting polymenrs to components where as Die refers for the tool used for sheet metal to pressed components
