Description

Slipper block loose core device

Technical field

Technical field of mold is the utility model is related to, more particularly to a kind of slipper block loose core device.

Background technology

Working of plastics becomes increasingly complex, the also more and more higher of the requirement to injection mold.Part plastic product height is higher, such as Fruit uses common depanning mode, and will design very big, very thick of mould is, it is necessary to which the bigger equipment injection of model, injection cost increase Add, and product ejection is difficult, and production is unstable.

Product is erected to mold, eject under common depanning mode, and because product is longer, the thickness and ejection distance of mould all can It is very big, the larger injection machine equipment of model is resulted in the need for be molded production, and mould development cost and injection production cost are very high.

Utility model content

The utility model is directed to problem and shortage existing for prior art, there is provided a kind of new slipper block loose core device.

The utility model is that solve above-mentioned technical problem by following technical proposals：

The utility model provides a kind of slipper block loose core device, and its feature is that it includes an executing agency and a sliding block is taken out Cored structure, the slide block core pulling structure are arranged between two press strips of an injection mold；

The slide block core pulling structure includes a take-up housing, a connecting rod, a T-shaped block and two latch segments, and the one of the take-up housing End side surface offers a circular groove to match with part to be detached, and the part to be detached is fixed in the circular groove, the sliding block Seat on offer one first groove, the T-shaped block is placed in first groove, the both sides of the take-up housing and close to first groove also Offer the second groove, each latch segment be placed in corresponding in the second groove, the other end of the take-up housing and first recessed positioned at this The avris of groove is provided with limited block, and the executing agency is connected by the connecting rod with the T-shaped block, the T-shaped block respectively with this two Individual latch segment phase clamping.

It is preferred that the executing agency is hydraulic jack.

On the basis of common sense in the field is met, above-mentioned each optimum condition, can be combined, produce the utility model respectively compared with Good example.

Positive effect of the present utility model is：

Product is rotated by 90 °, horizontal positioned, using slide block core pulling structure, is changed the depanning mode of product, can be reduced mould Height, the size of tool, and product ejection is in small distance, and production is relatively stable, can effectively reduce mold thickness and mould ejection Distance, reduce the manufacturing cost and injection production cost of mould.

Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that is retouched The embodiment stated is the utility model part of the embodiment, rather than whole embodiments.Based on the implementation in the utility model Example, the every other embodiment that those of ordinary skill in the art are obtained on the premise of creative work is not made, all belongs to In the scope of the utility model protection.

As Figure 1-3, the present embodiment provides a kind of slipper block loose core device, and it includes a hydraulic jack 1 and a sliding block is taken out Cored structure 2, the slide block core pulling structure 2 are arranged between two press strips 3 of an injection mold.

Wherein, the slide block core pulling structure 2 includes a take-up housing 21, an oil cylinder connecting rod 22, a T-shaped block 23 and two lockings Block 24, the one end side of the take-up housing 21 offer a circular groove 25 to match with the part to be detached on product 4, and this waits to take out Off member is fixed in the circular groove 25, and one first groove 26 is offered on the take-up housing 21, and it is first recessed that the T-shaped block 23 is placed in this In groove 26, the both sides of the take-up housing 21 and the second groove is further opened with close to first groove 26, each latch segment 24 is placed in pair In the second groove answered, the other end of the take-up housing 21 and the avris of first groove 26 is provided with limited block 27, the liquid Compressing cylinder 1 is connected by the oil cylinder connecting rod 22 with the T-shaped block 23, the T-shaped block 23 respectively with the phase card of two latch segments 24 Connect.

After the completion of injection, mould die sinking 1mm or so stops, the then core pulling of hydraulic jack 1.Hydraulic jack 1 is connected by oil cylinder Extension bar 22 drives T-shaped block 23 to move, and when T-shaped block 23 is drawn back, the latch segment 24 on the both sides of T-shaped block 23 is synchronous to intermediary movements (T Shape block is connected with latch segment by inclined-plane with T grooves, sees Fig. 4).When T-shaped block 23 moves to setting position, that is, it is limited block 27 and blocks When can not retreat again, the latch segment 24 on both sides departs from press strip 3, and slipper block loose core starts, and product ejects after completing core pulling.

During matched moulds, slide block core pulling structure 2 is first resetted by hydraulic jack 1, and T-shaped block 23 moves on after the completion of reset, is led to The extruding for crossing inclined-plane and T grooves forces two latch segments 24 to open, outside lateral movement, into the locked slide block core pulling structure 2 of press strip 3.

In the utility model, product is rotated by 90 °, horizontal positioned to use sliding block core-pulling mechanism, can effectively reduce mould Thickness and mould ejection distance, reduce the manufacturing cost and injection production cost of mould.

Product is rotated by 90 °, horizontal positioned to be molded using slipper block loose core.If doing common slipper block loose core, because product compared with It is long, and product package power is larger after injection molding, direct core pulling is easy to draw bad product, causes deformation of products, and part can not make With.Using the slide block core pulling structure in the utility model, mould first opens 1mm or so, product, slide block core pulling structure and preceding mould point From, reduction frictional force, and preceding mould only leaves product 1mm or so, and product can be held during slipper block loose core, prevents product from becoming Shape.

Stress is, it is necessary to which preceding mould shovel is locked in injection molding process for sliding block, and anti-limited slip block retreats, in this case with regard to nothing Method realizes mould in incomplete die opening state sliding block core pulling.Using the slide block core pulling structure in the utility model, sliding block itself Increase clamping mechanism, such sliding block can at any time core pulling locked without forward mould shovel, pipe mold is not either with or without beating Open.

Although the foregoing describing specific embodiment of the present utility model, it will be appreciated by those of skill in the art that These are merely illustrative of, and the scope of protection of the utility model is defined by the appended claims.Those skilled in the art Member can make numerous variations or repair to these embodiments on the premise of without departing substantially from principle of the present utility model and essence Change, but these changes and modification each fall within the scope of protection of the utility model.
