Blow molding cosmetics cosmetics packaging hose production exhaust gas in the mould cavity
For discharge blow molding cosmetics cosmetics packaging hose production as soon as possible the air in the mold, the mold cavity open exhaust system, concrete and the following way.
as type embryo constantly blowing, the air cavity in the clip would gather in the sag, groove, and the place such as corner, as the time, to open a vent in these areas. The diameter of the vent should be appropriate for assembly on the products surface convex sets, starts to sag, generally take a 0. 1 - 0. 3mm。 The length of the vent should be as small as possible. Vent and cross section larger channel are linked together, to reduce the air resistance.
another way is to drill a hole diameter within the cavity, and grinding a into the exhaust clearance within stick into the hole. Also can be used to open a triangle worse or circular arc groove exhaust embedded bar. Such embedded bar exhaust gap is smaller than the diameter of the vent, but the exhaust channel cross section is larger, and can accurately ensure exhaust when machining gap.
