Title: Burr prevention method
Inventor: SENGOKU TAKEHIRO
IPC: B29C45/26
Filed: 1993-12-27
Abstract: PURPOSE:To prevent burrs from occurring in clearances by setting the position of the gate of a die where a clearance occurs from the cavity at the time of die clamping so that after a resin entering through the gate reaches the clearance and solidifies, the resin may fill the cavity completely. CONSTITUTION:In a die for injection molding with a metal inserted, a clearance 12 occurs between an insert metal 1 and a die 8 and a resin penetrates into the clearance 12 and causes burrs, Thus in a die where a clearance 12 occurs, extending from the cavity, the position of the gate is set so that after a resin material penetrating into the cavity 10 via the gate reaches the clearance 12 and solidifies, the resin may fill the cavity 10 completely. When pressure rises up to retaining pressure after complete filling, solidified resin material prevents the resin material from penetrating into the clearance 12. It is desirable to form a recess 14 to absorb the dispersion of burrs near the cavity at the end face of the die.
