Since the present embodiment concave surface is vertically disposed, so the upper side and lower side of the bogging down area 1 of the present embodiment is all provided with
There is the nail position 4 of uniform wall thickness being obliquely installed outward.Benchmark section in this way above and below nail position can shape well.
It is to the fraction defective statistical data with a filling bottle with bogging down area below:
It can be seen that transition face has preferable improvement to deformation fraction defective, and nail position significantly affects filling fraction defective, but
It is the scheme for scheme or " the no nail position " for whether " having nail position (no transition face) ", overall fraction defective or unusual
Height, 1% or more fraction defective cannot be used for batch production, and the effect of the scheme of " having nail position (having transition face) " goes out
It is good to expect, and fraction defective reaches the level for being provided with the closing waist bottle of spiral raised line.The filling is bad to lack material for bottle body
It is bad.
By a large number of experiments and mold flow analysis, discovery is not that simple being provided with nail position or transition face is arranged can reach
To lower fraction defective, in those skilled in the art's eye, the nail position of no transition face should be just to be in best state, because

Vertical size on face is HSide, outward inclined angle of the nail position 4 on lateral section is ESide, in which:When plastics can be allowed to flow through nail position in this way, plastics flowing front is smooth, and reduction refers to
Issuable stress on first position, to prevent from deforming.The present embodimentIfWhen, come then shaping
Nail position be easy for deforming.
Above size is limited, there is extraordinary effect on 20mm < L < 200mm filling bottle, and L is less than
The closing waist filling bottle of 20mm and L > 200mm still can refer to above-mentioned size restriction and be designed, the L=of the present embodiment
100mm.When L is equal to 199mm, if other above-mentioned parameter constants, then filling fraction defective is 0.03%, deform bad
Rate is 0.02%, that is, L bigger, and deformation fraction defective can decline, but filling fraction defective can slightly rise therewith, this is mainly
Caused by changes in process parameters, similarly, as L=19mm, filling fraction defective is 0.01%, and deformation fraction defective is 0.052%.
Angle formed by the upper side ring surface of upper groove and the upper side ring surface of upper groove is B, between upper groove and closing waist section
Spacing is C, and the groove depth of upper groove is D, and the groove depth of lower groove is M, and the bottom width of lower groove is N, lower groove and closing waist section it
Between spacing be O, in which: 60 °≤B≤90 °, 1.5mm≤C≤8mm, 3mm≤D≤8mm, 1.5mm≤M≤4mm, 1mm≤N
≤4mm,1mm≤O≤4mm.B=60 °, C=2mm, D=3mm, M=4mm, N=3mm, O=5mm of the present embodiment.This range
It is interior, it can guarantee the stabilization of fraction defective, and those skilled in the art can be according to actual appearance needs, to above-mentioned size upper
It states in range and is adjusted.
