Une surface d'extrémité de travail de la plaque de fixation inférieure (4) est agencée avec deux blocs de positionnement (40), un bloc de coupe de moule inférieur (43) et un bloc de formation de moule inférieur (42). Un canal de guidage (41) est formé entre les deux blocs de positionnement (40). Le bloc de coupe de moule inférieur (43) est situé au niveau de l'extrémité du canal de guidage (41). Un bloc de coupe de moule supérieur (33) et deux trous de positionnement (30) sont agencés sur la plaque de pression (3), et chaque trou de positionnement (30) correspond à la forme du bloc de positionnement correspondant (40). Une pluralité d'éléments élastiques est agencée entre la plaque de pression (3) et la plaque de fixation supérieure (2). Un bloc de formation de moule supérieur (32) est agencé sur la surface d'extrémité inférieure de la plaque de pression (3) et l'extrémité de travail du bloc de formation de moule supérieur (32) passe à travers la plaque de fixation supérieure (2) et la plaque de pression (3) et est exposée. Le mécanisme de poinçonnage réalise la formation de bossage et le poinçonnage d'encoche dans une station, optimise la structure du moule, améliore le cycle de production, réduit le nombre de moules et réduit en outre le coût de production.
