The invention discloses a multifunctional jig for metal implanting and product withdrawal. The multifunctional jig comprises a positioning jig and a capturing jig, wherein the capturing jig comprisesa product absorption mechanism and a metal sheet implanting mechanism. Through matched using of the positioning jig and the capturing jig, three main steps of capturing a to-be-processed metal piece,withdrawing a formed product from a high-temperature mould and burying the to-be-processed metal piece into the high-temperature mould is rapidly completed. The multifunctional jig is implemented viathe specific working processes of: manually putting the to-be-processed metal piece into the positioning jig, absorbing the to-be-processed metal piece from the positioning jig by the capturing jig, enabling the capturing jig to approach to the high-temperature mould, after the high-temperature mould is opened, absorbing the formed product from the mould by the capturing jig; and putting the to-be-processed metal piece into the high-temperature mould by the capturing jig. The capturing jig is connected with an automatic manipulator, and the positioning jig is put at a place far away from the high-temperature mould, so that the process of withdrawing products and putting metal pieces can be replaced, operation is carried out automatically, and then operation is safe, reliable, efficient andaccurate.
