Description
Technical field
The utility model relates to mould, especially has side core-pulling mould.
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 slide guide slot type side core-pulling mechanism, and it comprises top clamping plate, slide block, Bottom clamp plate, camshaft bearing and slide guide frid; Described camshaft bearing is arranged on described slide block, described slide guide frid is arranged on the seat of top clamping plate, described slide guide frid acts on camshaft bearing, camshaft bearing slides in slide guide frid, described slide block slides along the guide runner in Bottom clamp plate, guide runner in described slide guide frid and the angle in die sinking direction are divided into two sections, and initial stage guide runner angle of loosing core is 10 ° ~ 25 °, and later stage guide runner angle of loosing core is 35 ° ~ 45 °.
As further improvement of the utility model, described in initial stage guide runner angle of loosing core be 12 ° ~ 23 °.
As further improvement of the utility model, described in later stage guide runner angle of loosing core be 37 ° ~ 43 °.
As further improvement of the utility model, described camshaft bearing is two, is separately positioned on the both sides of described slide block.
As further improvement of the utility model, loose core initial stage and later stage of loosing core respectively account for the half of whole stroke of loosing core.
The beneficial effects of the utility model are:
Contrast traditional Angle Pin core-pulling mechanism, in identical die space, the stroke of loosing core of slide guide frid can become longer, therefore when identical core pulling distance, can effectively reduce the size of mould.The resistance Qu Nengli of slide guide frid is strong, therefore goes for longer core pulling distance and larger ejection resistance, can adopt rapid mould opening-closing when mould is produced, and the design effectively can improve the efficiency of mould when production and security.Contrast conventional cylinder core-pulling mechanism, die size is less, and production mould does not need extra time of loosing core and auxiliary equipment, can not pollute plastic and production environment, and on mould, under machine, machine installation and debugging are convenient, production energy-conserving and environment-protective.

Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
Drawing reference numeral is: top clamping plate 301; Slide block 303; Bottom clamp plate 304; Camshaft bearing 307; Slide guide frid 308.
As shown in Figure 7 to 10, a kind of injection mold slide guide slot type side core-pulling mechanism, comprises slide block 303, slide guide frid 308, camshaft bearing 307.Camshaft bearing 307 is arranged on slide block 303 both sides, slide guide frid 308 is arranged on top clamping plate 301, described slide guide frid 308 acts on camshaft bearing 307, camshaft bearing 307 can slide in slide guide frid 308, described slide guide frid 308 drives slide block 303 to loose core, and slide block 303 can slide along the guide runner in Bottom clamp plate 304.The angle in the guide runner in slide guide frid 308 and die sinking direction is divided into two sections, and initial stage guide runner angle of loosing core is 10 ° ~ 25 ° (ɑ 1 as in Fig. 7), and later stage guide runner angle of loosing core is 35 ° ~ 45 ° (ɑ 2 as in Fig. 7).
During die sinking; slide guide frid 308 above cover half panel seat 301 acts on the camshaft bearing 307 on slide block 303; camshaft bearing 307 slides according to the track of the guide runner in slide guide frid 308; slide guide frid 308 drives slide block 303 to slide along the guide runner in Bottom clamp plate 304; until camshaft bearing 307 departs from slide guide frid 308, complete slide block 303 and to loose core action.The guide runner of slide guide frid 308 and the angle in die sinking direction are divided into two sections, initial production of loosing core resistance of loosing core is large, guide runner angle ɑ 1 adopts 10 ° ~ 25 ° less angles, the conversion efficiency of raising power, the resistance of later stage slipper block loose core of loosing core is less, and guide runner angle ɑ 2 can adopt 35 ° ~ 45 °.
Above content is in conjunction with concrete preferred embodiment further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, some simple deduction or replace can also be made, all should be considered as belonging to protection domain of the present utility model.
