Description
Technical field
The present invention relates to footwear mould technical field, more particularly to a kind of even side PU injection moulding shoe moulds.
Background technology
In existing shoe-making process, the method that sole is combined with footwear body mainly has two kinds, and one kind is by sole and footwear body list
Solely make, then using cold bonding technique that sole is bonding with footwear body, another continuous-upper injection technique for liquid PU, wherein connecting
Help the production efficiency of Shooting Technique higher, footwear body (including upper of a shoe and sole face for being connected with upper of a shoe) and the combination of sole are more firm
Gu, come unglued problem in the absence of the sole of the shoes made by cold bonding technique.
Mould used in traditional continuous-upper injection technique includes left side mould, the right mould and bed die, and footwear body is enclosed on shoe last,
Complete sole shape die cavity can be formed after left side mould and the right mould matched moulds, bed die is located at the lower section of left side mould and the right mould,
Bottom for closing sole shape die cavity, being sheathed on the sole face of the footwear body of shoe last can be placed in above-mentioned sole shape die cavity, it
Backward type intracavitary injection liquid PU material, after after shoe sole cures shaping, after die sinking, sole is footwear with footwear body curing molding.
But, by folder frame its bottom Zhou Shixian is clamped because shoe last positioning is pure, its manual operations positions and can deposit error and cause anxiety
Degree differs and easily misplaced, therefore product periphery flash phenomena often occurs in injection moulding process, thus greatly increases
The waste of raw material, and the edge quality of even side piece can be caused bad.
The content of the invention
To overcome the technological deficiency that prior art is present, the present invention provides a kind of even side PU injection moulding shoe moulds, beneficial to positioning last carving
Head simultaneously ensures that liquid PU material will not run side flash, and neat in edge is attractive in appearance.
The technical solution that the present invention is used is:
One kind even side PU injection moulding shoe moulds, including with the last carving laid the die shoe of chamber, be inlaid in placement intracavitary and convex die shoe
Cope plate and be arranged in the retractable left frame and the right side between die shoe and cope plate that head and die shoe side are hinged
Frame, the opposite sides of the left frame and right center are provided with the convex contouring identical mounting hole with shoe last, the last carving of the shoe last
The back side is installed in annular groove outside the simultaneously elastic separated material circle of evagination, the elastic separated material circle provided with annular groove and adaptation
The madial wall of end face and mounting hole closely offsets.
Preferably, be respectively equipped with air discharge duct on the left frame top surface and right center top surface, be provided with the air discharge duct with
The exhaust outlet that placement chamber below elastic separated material circle is connected, some transverse directions are provided with and communicated between the air discharge duct and mounting hole
Groove.
Preferably, the first sealing ring, first sealing ring are provided with corresponding to the cope plate inner face of air discharge duct periphery
Gas hole and charging hole are provided with the cope plate position inside enclosed.
Preferably, it is respectively equipped with sealing strip on the left frame and the contact surface of right center opposite sides.
Preferably, the die shoe top surface for laying chamber periphery is provided with the second sealing ring, and the left frame and right center are closed
Correspondence is pressed on the top of the second sealing ring after conjunction.
Preferably, the radial section of the annular groove is in the opening trough body structure of outer narrow inner width, the elastic separated material circle
Compression is arranged in annular groove and relative last carving back side evagination 0.5mm~0.8mm, and the elastic separated material circle is away from the last carving back side
Lower surface is in the inclined-plane of outside inclined upward.
Preferably, the bottom width 5mm of the annular groove, top width 3mm, depth is 3mm.
Preferably, annular protrusion, the annular protrusion and elastic separated material circle are additionally provided with the madial wall of the mounting hole
Lower surface compression fit.
Beneficial effects of the present invention:Due to being provided with the last carving back side in annular groove and elastic separated material circle, left frame and the right side
Closely offseted with elastic separated material circle after frame closure, one is manufacture requirement of the reduction to left frame and the mounting hole madial wall of right center
And difficulty, two be that can ensure to avoid the shoe last in foamed forming process from producing horizontal direction the stable holding positioning of shoe last
On skew, three be to avoid liquid PU material from running side flash, it is ensured that even side piece neat in edge is attractive in appearance, and four be in outside using lower surface
The elastic separated material circle of inclined upward assigns and the stabilization of PU expanded materials is coated and limited descending effect, and reduction is due to PU foaming
The active force of generation makes the adverse effect of elastic separated material circle deformation;Further set on mounting hole madial wall and elastic separated material
The annular protrusion of lower surface compression fit is enclosed, elastic separated material circle can be avoided by the pressure produced when PU foams by annular protrusion
Power effect is lower and deforms, distort or material leakage, ensures the neat fine quality at even side piece edge significantly.
