Description
Technical field
The utility model relates to mould, particularly relates to the transparent plastic part mould being suitable for stroke of loosing core greatly.
Background technology
Tradition Long Distances side core-pulling mould generally adopts Angle Pin to loose core and hydraulic cylinder loosing core two kinds of structures.
Fig. 1, Fig. 2, Figure 3 shows that Angle Pin pulled core structure.Angle Pin 102 angled with mould open/close mould direction in Fig. 3 is fixed on top clamping plate 101, and slide block 103 can slide in the guide runner of Bottom clamp plate 104.During die sinking, mould opening force is acted on slide block 103 by Angle Pin 102, forces slide block 103 to slide in the guide runner of Bottom clamp plate 104, until Angle Pin 102 departs from slide block 103 completely, can complete action of loosing core.
" mechanical design handbook " the 20th section " table 20-3-33 " advise the angle safety value in Angle Pin and folding mould direction general≤25 °, when the occasion at large core pulling distance, the length of Angle Pin will be very long, in order to increase Angle Pin resistance Qu Nengli, it is larger that bevel lead column's diameter often designs, and the installing space of core-pulling mechanism will increase, the size of corresponding mould just needs to become large, to loose core the occasion of resistance, need to slow down out closure pressing speed, prevent Angle Pin bending and fracture.Above problem all can cause Mold Making and production cost to increase, and produce and also have certain security risk, therefore general large core pulling distance is large, and ejection resistance is also large, and slide block does not adopt Angle Pin to loose core.
Adopt Fig. 4, Fig. 5, Figure 6 shows that hydraulic cylinder loosing core structure.In Fig. 6, slide block 203 can slide in the guide runner of Bottom clamp plate 204, and hydraulic cylinder 205 is fixed on Bottom clamp plate 204, and hydraulic cylinder piston rod 206 is fixed on slide block 203 afterbody.In figure, 201 is top clamping plate.After mould die sinking, the action of Hydraulic System for Injection Moulding Machine hydraulic control cylinder forces slide block to slide in the guide runner of Bottom clamp plate, realizes loosing core.This structure is not generally used in the occasion of producing medical treatment and food-related products, easily produces hydraulic fluid and reveals, have the possibility polluting plastic and production environment during hydraulic cylinder installation and removal.Hydraulic cylinder loosing core needs to loose core after die sinking completes again, rear product of having loosed core takes out, just can matched moulds after needing again to reset, these two actions just need extra increase injection cycle minimum 2-3 second, if injection machine is non-hydraulic system, also need additional configuration hydraulic pump to coordinate to produce, hydraulic pump runs to be needed to be equipped with electro-motor, need to consume certain electric energy, the outside that hydraulic cylinder is arranged on mould can cause die shape larger, usually need to be equipped with large-tonnage injection machine and improve molar amount cooperation production, on mould, under machine, machine needs connected pipes and sensor line, need at substantial time installment and debugging.Above problem all causes production cost to increase, and produces and also has potential safety hazard.
Tradition core-pulling mechanism, when being applied to the transparent plastic part mould of Long Distances, easily causing plastic to occur the problem of de-flower, affects the yields of plastic when loosing core.
Utility model content
In order to solve problem in prior art, the utility model provides a kind of injection mold diagonal-cut rack formula side core-pulling mechanism, comprises top clamping plate, slide block, Bottom clamp plate, determines diagonal-cut rack, moves diagonal-cut rack, guiding rail mechanism; Describedly determine diagonal-cut rack and be arranged on above described top clamping plate, described dynamic diagonal-cut rack is arranged on described slider tail, and described guiding rail mechanism is arranged between described slide block and described Bottom clamp plate, and described slide block is arranged in the guide runner of described Bottom clamp plate; Determine the dynamic diagonal-cut rack that diagonal-cut rack acts on the slider tail in the guide runner of Bottom clamp plate when mould is opened on top clamping plate, force slide block to slide along the guiding rail mechanism on Bottom clamp plate.
As further improvement of the utility model, describedly determine tooth on diagonal-cut rack and depanning direction is 28 ° ~ 47 °.
As further improvement of the utility model, describedly determine tooth on diagonal-cut rack and depanning direction is 30 ° ~ 45 °.
As further improvement of the utility model, describedly determine tooth on diagonal-cut rack and depanning direction is 33 ° ~ 40 °.
As further improvement of the utility model, described guiding rail mechanism is arranged between slider bottom and Bottom clamp plate.
The beneficial effects of the utility model are:
This core-pulling mechanism contrasts traditional core-pulling mechanism, and this core-pulling mechanism is arranged on the outside of mould template completely, can save the installing space of core-pulling mechanism template inside, reduces the size of mould; The resistance Qu Liqiang of diagonal-cut rack, the angle in the tooth of diagonal-cut rack and the direction of die sinking can be designed into 30 ° ~ 45 °, can realize the core pulling distance more grown in identical space, is suitable for the occasion of larger resistance of loosing core; Mechanism produces the risk not polluting plastic and environment; do not need auxiliary equipment and extra loosing core the time; especially applied for transparent plastic core-pulling die; the track of slide block linearly guide rail slides; slide block slides de-colored problem when steadily can effectively prevent transparent plastic part from loosing core; reduce the production cost of mould, improve the yields of plastic.
