A basic skating system consists of the following components: -Key: the function used to skewer the impact move the sliding blocks. The angle of oblique pin with stand is usually about 5 → 28°. The magnitude of the angle and the length of the PIN decides the journey of sliding side core. -Sliding Cores: part of the mold for forming details, often slipping across the plate against the worn and kept in the ray system. -Ray: keep sliding cores, ensure accurate motion sliding core and gently without any of the move. -Plate against Trail: creating surface for sliding core moves, abrasion resistant throughout the lifecycle of the mold. 140 -Keep structure: keep sliding core at the time of the mold open completely. -Core: the sliding wedge Blocks standing still in the process of injection. The entire pressure resistant wedge, oblique PIN without touching the core slide throughout this process.
