Description
Technical field
The utility model relates to a kind of mould applications, relates to a kind of arc core pulling structure of injection mould specifically.
Background technology
In the design process of Mold for Plastics, often can run into shape in various forms of circular arc, make the design of mould become very difficult.
Along with market is day by day complicated to the requirement of injecting products, product needs be provided with arc position to complete the function needs of himself, this kind of situation is more and more general.For the ease of this arc core-pulling, generally adopt arc core pulling structure.In this arc core pulling structure, general employing slide block helps looses core.In arc core-pulling process, generally first will be extracted out from arc position by circular arc mold insert and carry out slipper block loose core again, operation mainly causes overlap in order to prevent to product sheet like this, affects yield rate.
This pulled core structure can be designed very complicated of traditional arc core-pulling and poor effect of loosing core, traditional arc core pulling structure by interiorly curvedly loosing core, connecting rod, interiorly directly to loose core, the outer rotating core-pulling mechanism formed of directly loosing core, being kept straight on by oblique slider guide, the pull bar that lags successively segmentation, extraction is inside and outside directly looses core, and is affected the technical scheme of interior curved rotary core pulling of loosing core by connecting rod.The pulled core structure complex operations of program design is loaded down with trivial details, and easily by clamping stagnation, the effect thus impact is loosed core.
In sum, the main weak point at present for the arc core pulling structure of injection mold is complex structure complex operation, and easily forms clamping stagnation, affects effect of loosing core.
Summary of the invention
The technical problems to be solved in the utility model there are provided a kind of arc core pulling structure of injection mould, and this structure adopts does not have cylinder as power source, and circular arc core and straight shape side core are loosed core as pulled core structure.
For solving the problems of the technologies described above, the utility model is realized by following scheme: a kind of arc core pulling structure of injection mould, this pulled core structure comprises oil cylinder, pull bar, connecting rod, circular arc core, side core, slide block, described oil cylinder telescopic end cylinder lever connecting rod, pull bar is flexibly connected connecting rod, and the connecting rod other end is movably connected on circular arc core, offers arc groove in described circular arc core upper end, circular arc core is placing one end connection side core of product plastic, and described side core lower end is connected with slide block.
Further, the radian of described circular arc core is 60 degree.
Further, the radian of described arc groove is 60 degree.
Further, described side core linearly type.
Further, the connecting portion of described connecting rod and circular arc core is arranged on arc groove axis.
Further, the length of described connecting rod is that arc radius is divided by 5.
Further, conical boss is adopted to locate between described circular arc core and side core.
Relative to prior art, the beneficial effects of the utility model are: reliable in action of loosing core, structure is relatively simple, adopt cylinder device, make to loose core action more precisely, solve cambered surface precision in prior art inadequate, cause the problem that fraction defective is high, by comparing with the structure of traditional arc core-pulling, the production efficiency for plastic significantly improves.
Accompanying drawing explanation
The plastic that Fig. 1 produces for the utility model arc core pulling structure.
Fig. 2 is the arc core pulling structure of the utility model injection mould.
Mark in accompanying drawing: oil cylinder 1; Pull bar 2; Connecting rod 3; Arc groove 4; Circular arc core 5; Plastic 6; Side core 7; Slide block 8.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is explained in detail.
Please refer to accompanying drawing 1 ~ 2, the arc core pulling structure of a kind of injection mould of the present utility model, this pulled core structure comprises oil cylinder 1, pull bar 2, connecting rod 3, circular arc core 5, side core 7, slide block 8, described oil cylinder 1 telescopic end cylinder lever connecting rod 2, pull bar 2 is flexibly connected connecting rod 3, connecting rod 3 other end is movably connected on circular arc core 5, arc groove 4 is offered in described circular arc core 5 upper end, circular arc core 5 is placing one end connection side core 7 of product plastic 6, described side core 7 lower end is connected with slide block 8, the radian of described circular arc core 5 is 60 degree, the radian of described arc groove 4 is 60 degree, described side core 7 linearly type, described connecting rod 3 is arranged on arc groove 4 axis with the connecting portion of circular arc core 5, the length of described connecting rod 3 is that arc radius is divided by 5.
The utility model arc core pulling structure is according to its feature, and power source can be hydraulic cylinder or pneumatic cylinder formula or die sinking campaign.No matter be which kind of point-score, principle can be divided into substantially following several: sliding-block linkage is plastic as shown in Figure 1, form middle arc-shaped cavity, one end must be adopted along arc core-pulling, and the other end is linearly loosed core.
Structure as shown in Figure 2, during die sinking, the piston moved beneath left of oil cylinder 1, drives circular arc core 5 to move by pull bar 2 and connecting rod 3, and due to the restriction of arc groove 4, circular arc core 5 along circular motion, thus can only complete arc core-pulling.Meanwhile, the slide block 8 of the other end, under the drive of Angle Pin, moves downward, and completes the action of loosing core of side core 7.Oil cylinder 1 upper direction to the right during matched moulds, drives circular arc core 5 to produce reseting movement by pull bar 2 and connecting rod 3; Side core 7 and slide block 8 reset under the effect of Angle Pin, adopt conical boss to locate between circular arc core 5 and side core 7.
This structure, reliable in action of loosing core, structure is relatively simple, and hydraulic cylinder makes power source stablize, and the home position of deep-slotted chip breaker is extremely important, if select improper meeting to cause loosing core unsuccessfully, so the space of loosing core needed is larger.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every utilize the utility model description and accompanying drawing content to do equivalent structure or equivalent flow process conversion; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present utility model.
