.-Hand side of the core of withdrawal, the top surface of the lower latch should skewers 0:05 ÷ 0.1 mm surface core plate, in the process of molding, core pin pulled oblique done, move inside. To block radius of the collision from the bottom of the plastic on the core product withdrawal, the underside must be higher than the top of the structure, in the meantime, the symmetrical movement of radius S board structure must be provided with S1 S.Vi wider so, obstacles like the banks can avoid a collision on the core withdrawn. S1> S.
2) of the closing angle β should take about 5 ÷ 25 °, while the angle α on the core navigation mechanism draw of less than or equal to β, α ≤ β. Prevent collisions between latch oblique and core part of the protruding beveled.
3) structure with recovery function, the length of the rounded edges is best to be wider, the 4 corners of the slider so as to conveniently rounded corners benefit the milling process. Designed to ensure stability and certainty of recovery structure and extend the distance of the course.
4) When sliding friction occurs between the latch plate and hold the plate skewer pushed, I need hard surfaces to enhance abrasion resistance.
