Hand drawn inner core, the upper surface of the lower latch should slant 12:05 ÷ 0.1 mm surface core plate, in the molding process, closing the core oblique withdraw, 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 surface of the structure, meanwhile, face symmetrical movement of radius S board structure must be provided with S1 So what S.Vi wider, like shore obstacles can avoid collisions on the core withdrawn. S1> S.
The angle of β latch should take about 5 ÷ 25 °, while the angle α on the core navigation structure withdrawal of less than or equal to β, α ≤ β. Preventing collisions between latch oblique and core part of the protruding beveled
structure with functional recovery, length of rounded edges is best possible wider, 4 corners of the slider so as to facilitate round corners too milling process. The design ensures stability and certainty of the escapement and extend the distance of the course
when sliding friction occurs between the latch plate and hold the plate oblique thrust, have hardened surface to improve corrosion resistance
