Study on the Structure Improvement of Slanted-Guide-Pillar Core-Pulling Mechanism in Die-Casting Die
The slanted-guide-pillar core-pulling mechanism is the most commonly used side core-pulling mechanism in die-casting die. But when filling the die with pressure, aluminum leak frequently happens between lower motion-stopping surface of sliding block and side surface of moving die insert, since the clearance is bigger between side core and core hole. In many improved approaches, changing the lower motion-stopping surface of sliding block into upper motion-stopping surface of it or reducing the lower motion-stopping surface area is the simplest and reliable measure. The sliding block’s setback which occurs in die-casting process can be eliminated effectively and the workload of maintaining die can be reduced by this measure.
