Description
Technical field
The present invention relates to technical field of mold, more particularly to a kind of stripper apparatus based on buckle moulding.
Background technology
In injection mold technical field, be present buckle structure in many product surfaces, after injecting products shaping, be difficult at buckle
The demoulding, is easily caused at buckle during forced demoulding and damages.In order to prevent that buckle is damaged during the demoulding, with buckle generally on mould
Correspondence goes out to set push rod, and insertion slide opening in a slide opening, push rod is opened up on core rod, and the head of push rod is stretched into die cavity and product
The correspondence of upper buckle goes out, after product injection moulding, and push rod and product are stripped together, after product leaves die cavity, then by push rod
Separated with buckle.Then when product is molded, be present certain attachment force in the inwall of buckle and the head of push rod, hindered when extracting push rod
Power is larger, is also possible to cause buckle to damage while extracting push rod, stability is poor.
The content of the invention
The present invention is in order to solve buckle when the above-mentioned problems in the prior art is stripped there is provided a kind of buckle moulding
The stripper apparatus that the resistance that is subject to is small, effectively prevent buckle from damaging.
To achieve these goals, the present invention is adopted the following technical scheme that：
A kind of stripper apparatus based on buckle moulding, is arranged on die holder, and core rod is provided with die holder, and interior be provided with of core rod snaps into
Die cavity, the bottom of the core rod is provided with is provided with adapter sleeve, the company with snapping into the rectangular opening that die cavity is connected, described die holder
The upper end of female connector is fixed with two parallel connecting rods stretched into rectangular opening, and the upper end of two connecting rods, which is equipped with, stretches into fastening forming
The position snapped between matrix, two connecting rods in chamber is provided with slide bar, and the upper end of the slide bar is from two panels snaps into matrix
Between pass through, the lower end of slide bar is through adapter sleeve and stretches out outside adapter sleeve, and the bottom of the die holder is provided with pressing plate moving up and down,
The lower end of the slide bar is fixedly connected with the pressing plate.The parts such as pressing plate and outside oil cylinder, cylinder be connecteds, before product injection, are driven
Pressing plate rises, and the upper end of slide bar is passed through from two positions snapped between matrix, product injection moulding, before the demoulding, under pressing plate
Drop, band moving slide-bar declines, and now two panels lacks support between snapping into matrix, during the demoulding, when buckle is extracted, two panels fastening forming
The automatic inwardly deformation of piece, so as to ensure that buckle is damaged during the demoulding.
Preferably, the described lower end for snapping into matrix and the upper end of connecting rod rotate and connected.After slide bar declines, the demoulding
When, snap into matrix and inwardly rotate automatically, buckle snaps into matrix and hardly buckle is produced from when snapping into die cavity disengaging
Resistance, departs from so that it is guaranteed that buckle is stable, will not damage buckle.
Preferably, being provided with positive stop lug boss on the outside of the upper end of the connecting rod, the medial surface of the positive stop lug boss is outward-dipping,
The lower end outside for snapping into matrix is provided with the spacing inclined-plane coordinated with positive stop lug boss.Positive stop lug boss is used to limit fastening forming
The extreme position of piece.
Preferably, being provided with pilot hole in described adapter sleeve, the lower end of the pilot hole is provided with stop collar, and slide bar is upper
Limited block is provided with the position in pilot hole, the lower end of slide bar passes through stop collar.Limited block be used for limit slide bar rise, decline
Extreme position.
Preferably, the lower end of the adapter sleeve, stop collar is equipped with flange, described flange and the bottom of die holder pass through
Bolt connection.Flange is connected, easy for installation.
Preferably, the bottom of the die holder is provided with some guide pillars, described depression bar is connected with guide pillar, under the guide pillar
End is provided with connecting plate.Guiding, position-limiting action are played in lifting of the guide pillar to pressing plate, it is ensured that slide bar Stable sliding.
Therefore, the present invention has the beneficial effect that ejection resistance is small, effectively prevent buckle from damaging.
