Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is parting structural representation of the present utility model.
In figure: 1. die, 2. punch, 3. push pedal, 4. plastic mold, 5. punch retainer, 6. stop screw, 7. fixture, 8. support member fixed head, 9. dynamic model backing plate, 10. inner slide, 11. springs, 12. movable parts, 13. swing hooks, 14. grooves, 15. inner slide support members.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of core-pulling mechanism with indent working of plastics injection mould as shown in Figure 1, the punch 2 that there is die 1 and match with die 1, push pedal 3 is provided with between described die 1 and punch 2, plastic mold 4 is provided with in groove 1, the lower end of punch 2 is provided with punch retainer 5, the side of punch retainer 5 is provided with stop screw 6, its opposite side is provided with fixture 7, the lower end of punch retainer 5 is provided with the support member fixed head 8 connected by stop screw 6, the lower end of support member fixed head 8 is provided with dynamic model backing plate 9, the centre of support member fixed head 8 is provided with inner slide support member 15, the upper end of inner slide support member 15 is provided with inner slide 10, spring 11 is provided with between the inwall of inner slide 10 and punch retainer 5, the side of described support member fixed block 8 is provided with movable part 12 and is used for fixing swing hook 13, swing hook 13 side is arranged in fixture 7, the material of inner slide 10 can select 45 steel in carbon constructional quality steel or 20 steel, the side of die 1 is provided with groove 14, described groove 14 matches with swing hook 13.
The action of this mould core pulling completes primarily of structure co-controllings such as stop screw 6, inner slide 10, spring 11, inner slide supporting member 9 and swing hooks 13, the surfaces externally and internally of the common molding plastic part of die 1, punch 2 and push pedal 3, the lateral concave on inner slide 10 molding plastic part inwall.Now, stop screw 6 is in off working state, and spring 11 is in confined state, and swing hook 13 is in locking state, when mould starts somatotype, dynamic model backing plate 1 and supporting member fixed head 8 move to main parting direction under injection machine power drives, and due to the locking effect of swing hook 13, die 1 is fixed by relative with punch retainer 5, so cavity shape can not change, mould is opened along A face, because inner slide supporting member 15 is fixed between dynamic model backing plate 9 and support member fixed head 8, so can draw back.Now, inner slide 10 moves right under the effect of spring 11, and like this, the slide block end for molding plastic part indent will be drawn out of, and completes action of loosing core laterally therein.When inner slide 10 completely from working of plastics indent withdrawing out after, swing hook 13 now should be in critical index lock status, and stop screw 6 must be in off working state, after inner side core-pulling action completes, dynamic model continues to retreat under injection machine power drives, afterwards, stop screw 6 is had an effect, locking supporting member fixed head 8 and punch retainer 5 no longer produce relative motion, swing hook 13 unlocks simultaneously, mould is opened along main parting line B face, dynamic model drives plastic mold 4 entirety to retreat, until fall back on the suitable position ejected, punch 2 drives at injector dynamic model and continues to retreat, push pedal 3 is no longer moved under push rod ejection effect, thus plastic mold 4 is ejected from punch 2, realize the motor-driven demoulding of working of plastics, so far, this working of plastics single is produced complete, rear mold active and inactive mold close, enter the next production cycle.
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.
