It is arranged in second fixed plate 5, the positioning and guiding is passed through between first fixed plate 4 and first concave template 1
Portion 6 and connecting bolt 8 are connected.
For being similar to during the injection-compression molding of square articles, typically die cavity is formed using two form assemblies up and down
Mode, and can it is diagonal at two on add guide pillar.Exactly because the length and width of template are close, so in stable docking and anti-collision
In terms of touching deviation, it is desirable to which precision is not high, i.e., two guide pillars are just well positioned to meet firm effect.But in the production of big L/D ratio configuration
In the mould of product pressure injection, after one end of mould is by unexpected touch, along the axial direction of mould, whole die cavity can be all destroyed,
The problem of lower impressions groove is not corresponded in generation, the final object for causing shaping has the burr side of very big shape, so for big
The mould of draw ratio anomeric product pressure injection, its steadiness docked requirement will be substantially greater than the mould of common objects pressure injection.
In the present embodiment, second concave template 2 is arranged in second fixed plate 5, and first concave template 1 leads to
The effect of being fixedly clamped of first fixed plate 4 is crossed, it is ensured that the stable alignment work of the die cavity 3, wherein first cavity plate
Plate 1 is not pressurizeed directly by operating personnel and fastened, and effectively prevent because that surprisingly touches and the die cavity 3 is brought is harmful inclined
Move, after first fixed plate 4 is by unexpected touch, the dynamics touched only can be by the part of positioning and guiding portion 6 transmission
To first concave template 1, the offset amplitude of first concave template 1 is greatly reduced, the steady of the die cavity 3 is effectively protected
