Abstract
The utility model discloses Anti-jamming structure is ejected in a kind of mould, inner slide and inclined guide pillar including injection mold, inclined guide pillar are cooperated by clamping structure and inner slide, to drive inner slide is mobile to realize core pulling；The inner slide is equipped with block piece, prevents plastic solution from entering in the gap of clamping structure.The setting of the block piece, can prevent plastic solution from entering in the gap of clamping structure, and inclined guide pillar and inner slide is on the one hand avoided stuck phenomenon occur, to from frequent demoulding, repair a die, improve production efficiency；On the other hand injection-moulded plastic part is solved the problems, such as in cooperation director's flash of inner slide and inclined guide pillar, to improve the quality of injection-moulded plastic part.
Description
Technical field
The utility model relates to injection molding art, more particularly to ejecting Anti-jamming structure in a kind of mould.
Background technique
In injection moulding process, the inner slide as punch-pin is a kind of injection mold of the prior art after injection molding
It is mobile come band movable slider by an inclined guide pillar, complete core pulling.Specifically, inner slide side is tiltedly installed with length up and down
Strip-shaped clamp groove, inclined guide pillar side corresponding tilt are provided with strip fixture block, and card slot and fixture block are engaged by clamping, and can be along inclined direction
Opposite sliding.Since inclined guide pillar and inner slide are simultaneously with plastics face contact, plastic solution is easily accessible the cooperation of card slot and fixture block
In gap, lead to occur the long flash of injection-moulded plastic part, inclined guide pillar and the stuck phenomenon of inner slide.
Utility model content
The utility model provides a kind of interior ejection Anti-jamming structure of mould, and which overcome ejecting structures in the mould of the prior art
Existing shortcoming.
The technical scheme adopted by the utility model to solve the technical problem is as follows: Anti-jamming structure is ejected in a kind of mould, packet
The inner slide and inclined guide pillar of injection mold are included, inclined guide pillar is cooperated by clamping structure and inner slide, to drive inner slide mobile real
Existing core pulling；The inner slide is equipped with block piece, prevents plastic solution from entering in the gap of clamping structure.
Further, the clamping structure includes the strip fixture block and the interior cunning that the inclined guide pillar side is obliquely installed
The strip card slot that block side is obliquely installed, fixture block and card slot are engaged by clamping, and opening of being only arranged by card slot bottom end of fixture block
Mouth slides in or out card slot；The block piece is located at card slot top.
Further, the cross section of the fixture block is in convex shape or swallow-tail form or I-shaped, the cross section shape of the card slot
Shape is adapted to therewith.
Further, the block piece is embedded on the inner slide, and the block piece top surface and the inner slide top
Face is concordant.
Further, the block piece is plate body structure.
Compared to the prior art, the utility model has the following beneficial effects:
The setting of the block piece clamping structure can be isolated with plastic solution, prevent plastic solution from entering card
In the gap of binding structure, inclined guide pillar and inner slide is on the one hand avoided stuck phenomenon occur, thus from frequent demoulding, repair a die,
Improve production efficiency；On the other hand injection-moulded plastic part is solved the problems, such as in cooperation director's flash of inner slide and inclined guide pillar, thus
Improve the quality of injection-moulded plastic part.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But a kind of mould of the utility model
Interior ejection Anti-jamming structure is not limited to the embodiment.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram one of the inner slide of the utility model (before block piece insertion)；
Fig. 3 is the structural schematic diagram two of the inner slide of the utility model (after block piece insertion)；
Fig. 4 is the structural schematic diagram of the inclined guide pillar of the utility model.
Specific embodiment
Embodiment referring to Figure 1 shown in-Fig. 4, ejects Anti-jamming structure, including injection molding in a kind of mould of the utility model
The inner slide 1 of mold and for driving the mobile inclined guide pillar 2 for realizing core pulling of the inner slide 1, leads between inclined guide pillar 2 and inner slide 1
It crosses and is obliquely installed and can be combined together with respect to the clamping structure of sliding.The inner slide 1 is equipped with block piece 3, to the card
Binding structure is isolated with plastic solution (plastic solution is for being molded into part), prevents plastic solution from entering clamping structure
In gap.
In the present embodiment, the clamping structure includes the strip fixture block 21 and institute that 2 side of inclined guide pillar is obliquely installed
The strip card slot 11 that 1 side of inner slide is obliquely installed is stated, fixture block 21 and card slot 11 are engaged by clamping, and fixture block 21 can only pass through card
The opening of 11 bottom end of slot setting slides in or out card slot 11；The block piece 3 is located at 11 top of card slot.
In the present embodiment, the cross section of the fixture block 21 is in convex shape, but not limited to this, for example, fixture block 21 is transversal
Face can also be dovetail-shape or I-shaped etc..The cross-sectional shape of the card slot 11 is adapted to the cross-sectional shape of fixture block 21.Such as
This, guarantees that fixture block 21 will not be exited from the notch of card slot 11.
In the present embodiment, the block piece 3 is plate body structure, and is embedded on the inner slide 1, and the block piece 3
Top surface and 1 either flush of inner slide.Specifically, the inner slide 1 is equipped with a caulking groove 12 in the top of its card slot 11, that is, is used for
Inlay the block piece 3.
The inclined guide pillar 2 is fixed on the hot runner manifold of injection mold, and inner slide 1 is in the fixed die insert of solid plate.
When injection molding, plastic solution enters in mold cavity, contacts with inner slide 1.Under the blocking of the block piece 3, inclined guide pillar 2 will not
With the molding face contact of plastic solution, plastic solution will not enter the cooperation of the fixture block 21 of inclined guide pillar 2 and the card slot 11 of inner slide 1
In gap.Injection molding terminates, and mold die sinking, under the collective effect of spring and die button, solid plate and hot runner manifold are first disengaged, interior cunning
Block 1 moves under the action of inclined guide pillar 2, to realize core pulling.Since plastic solution is no and inclined guide pillar 2 contacts, it is ensured that produce
Quality.Meanwhile inclined guide pillar 2 and the fit clearance of inner slide 1 can be increased suitably, 1 activity of inner slide is more suitable when making to be opened
Freely, reduce inclined guide pillar 2 and the stuck probability of inner slide 1.Frequent demoulding is avoided, is repaired a die, production efficiency is improved.
Above-described embodiment, which only is used to further illustrate, ejects Anti-jamming structure in a kind of mould of the utility model, but this is practical
It is novel to be not limited to embodiment, it is made by the above technical examples according to the technical essence of the present invention any simply to repair
Change, equivalent variations and modification, each falls in the protection scope of technical solutions of the utility model.
