Description
Technical field
The utility model relates to injection mould technical field, especially a kind of new gear rack type side core-pulling injection mold.
Background technology
Mould, in industrial production in order to injection moulding, blowing, extrude, various mould and instrument that the method such as die casting or forging forming, smelting, punching press obtains required product.In brief, mould is used to the instrument of formed article, and this instrument is made up of various part, and different moulds is made up of different parts.It realizes the processing of article profile mainly through the change of institute's moulding material physical state.When plastics such as injection moulding sidewall band is porose, pit, boss, on mould, the part at this place shaping just must make the part that can be displaced sideways, and is called moving core.First moving core must be extracted out before the plastic demoulding, otherwise just cannot the demoulding.The whole mechanism driving moving core to do to be displaced sideways is called side-parting core-pulling mechanism, is called for short side core-pulling mechanism.Traditional side core-pulling mould structure is complicated, complex operation, weak effect of loosing core.
Utility model content
The technical problems to be solved in the utility model is: overcome the deficiencies in the prior art, provides a kind of structure simple, the new gear rack type side core-pulling injection mold of loosing core effective.
The utility model solves the technical scheme that its technical problem adopts: a kind of new gear rack type side core-pulling injection mold, comprise cover half assembly and dynamic model assembly, cover half assembly comprises cover half cavity plate, described dynamic model assembly comprises moving platen and dynamic model cavity plate, be provided with the driving rack fixed head and driving rack push pedal that are fixedly connected with between moving platen and dynamic model cavity plate, driving rack fixed head is vertically installed with driving rack; Described dynamic model cavity plate center is provided with core and the tooth bar core of plastic requirement, and tooth bar core is connected with driven unit, and driven unit comprises the gear be arranged in dynamic model cavity plate, and tooth bar core and driving rack are positioned at gear both sides and equal and gears meshing; Be provided with plastic in cavity between described driving rack fixed head and dynamic model cavity plate and release assembly.
Further, described plastic is released assembly and is comprised the push pedal and push rod holder that are fixedly connected with, and push rod holder is vertically provided with push rod, and push rod contacts with plastic through core.
Further, described dynamic model cavity plate is provided with spring catch, and tooth bar core is provided with half slot, and it is spacing to tooth bar core that spring catch embeds half slot.
Further, described cover half cavity plate is provided with the release link that driving rack is resetted.
The beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, easy to operate, and by cooperatively interacting of tooth bar core, gear and driving rack, loosing core, it is effective to release, and improves product quality, accelerates speed of production.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model;
Wherein: 1. driving rack fixed head, 2. push pedal, 3. push rod holder, 4. push rod, 5. spring catch, 6. core, 7. half slot, 8. tooth bar core, 9. cover half cavity plate, 10. release link, 11. gears, 12. driving racks, 13. moving platens, 14. driving rack push pedals, 15. dynamic model cavity plate.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
New gear rack type side core-pulling injection mold as shown in Figure 1, comprise cover half assembly and dynamic model assembly, cover half assembly comprises cover half cavity plate 9, dynamic model assembly comprises moving platen 13 and dynamic model cavity plate 15, be provided with the driving rack fixed head 1 and driving rack push pedal 14 that are fixedly connected with between moving platen 13 and dynamic model cavity plate 15, driving rack fixed head 1 be vertically installed with driving rack 12; Dynamic model cavity plate 15 center is provided with core 6 and the tooth bar core 8 of plastic requirement, tooth bar core 8 is connected with driven unit, driven unit comprises the gear 11 be arranged in dynamic model cavity plate 15, and tooth bar core 8 and driving rack 12 are positioned at gear 11 both sides and all engage with gear 11; Be provided with plastic in cavity between driving rack fixed head 1 and dynamic model cavity plate 15 and release assembly.
Plastic is released assembly and is comprised the push pedal 2 and push rod holder 3 that are fixedly connected with, and push rod holder 3 is vertically provided with push rod 4, and push rod 4 contacts with plastic through core 6; Dynamic model cavity plate 15 is provided with spring catch 5, tooth bar core 8 is provided with half slot 7; Cover half cavity plate 9 is provided with the release link 10 that driving rack 12 is resetted.
During die sinking, dynamic model part is moved to the left, and plastic is moved to the left with dynamic model part after wrapping in and tooth bar core 8 being deviate from from cover half cavity plate 9, and the solidifying material of sprue connects together with plastic and is moved to the left under sprue puller effect.When ejector pin contact with injector of driving rack push pedal 14, driving rack 12 transfixion, dynamic model part continues to retreat, and driving rack 12 driven gear 11 does anticlockwise rotation, thus makes the tooth bar core 8 engaged with gear 11 do oblique side to loosing core.Complete when loosing core, driving rack fixed head 1 contacts with push pedal 2, and promotes push pedal 2 plastic is released by push rod 4.During matched moulds, release link 8 makes driving rack 12 reset.Release link 8 also plays the effect of wedge block when injecting.
This new gear rack type side core-pulling injection mold structure is simple, reasonable in design, easy to operate, and by cooperatively interacting of tooth bar core 8, gear 11 and driving rack 12, loosing core, it is effective to release, and improves product quality, accelerates speed of production.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
