Detailed description of the invention
Referring to figs. 1 through Fig. 6, the utility model installation foot pulled core structure embodiment is described further.
As shown in Figure 1, for processing this kind of installation foot a time due to the back-off a1 small volume on its installation foot a, more fragile, and be tilt.In the process of the demoulding, some mechanical oscillation will affect the shape of back-off a1, thus need stable core-pulling mechanism to carry out the demoulding to it to loose core.
As shown in Figure 2, a kind of installation foot a pulled core structure, comprise cover half frame 1, dynamic model frame 2, in take out block 3, slide block 4 and lock dog 5; Cover half frame 1 is fixed on cover half, and dynamic model frame 2 is fixed on dynamic model, and fixed half and moving half is all prior art, no longer repeats the structural principle of the cover half in mould, dynamic model at this.
The main points of this programme are pulled core structure, and dynamic model frame 2 and cover half frame 1 are all provided with a lot of louvres, and the side of dynamic model frame 2 is provided with the die cavity 6 for installation foot a injection moulding, by toward injected plastic in die cavity 6, just can form product as shown in Figure 1.By the time, after plastics cooling, the demoulding is started.The passage 7 taking out block 3 and slide block 4 slippage in supplying is provided with in described cover half frame 1; Passage 7 has the effect of guiding, is tilted the front end of passage 7, rear end level, and the direction of loosing core that the moving direction taking out block 3 so has just been arranged to tilt is moved, and the moving direction of slide block 4 is exactly the moving direction of level, thus makes the process of loosing core more stable.
As shown in Figure 3,4, inside take out block 3 and to be arranged in dynamic model frame 2 and loose core direction slippage in edge in cover half frame 1 in, conflict near die cavity 6 and with the back-off a1 of installation foot a in the front end of taking out block 3 in described, the rear end of taking out block 3 in described is provided with slide rail 31; Slide rail 31 is "T"-shaped, and moving process is more stable, stressed more even.The front end of described slide block 4 is provided with the chute 41 coordinated for slide rail 31, and make moving process more convenient by the cooperation of slide rail 31 and chute 41, the slippage in passage 7 of described slide block 4, described slide block 4 rear end is provided with the guide through hole 42 of inclination; The bottom of described lock dog 5 is fixed with the guide pillar 51 coordinated with guide through hole 42 size, and described guide pillar 51 to stretch in guide through hole 42 and coordinates with slide block 4 slippage, and the top of described lock dog 5 is fixedly connected with cover half frame 1; Wherein, cover half frame 1, lock dog 5, slide block 4 and interior block 3 of taking out link successively, and cover half frame 1 and lock dog 5 move upward and drive slide block 4 to move backward, then take out block 3 in driving and move along direction of loosing core.
In order to make slide block 4 slipping more stable, the demoulding is loosed core more accurate.Be removably connected with the first locating part 8 in dynamic model frame 2, described first locating part 8 is conflicted with the bottom of slide block 4, and the moving direction limiting slide block 4 is horizontal shifting.First locating part 8 is bolted on dynamic model frame 2, thus on detachable maintaining, first locating part 8 can well dismounting and change, thus improves the mold use life-span, can not scrap whole mould because of the damage of a widget or affect whole mold use.
Also be removably connected with the second locating part 9 in dynamic model frame 2, described second locating part 9 near the rear end of slide block 4, and limits the movable distance of slide block 4.Second locating part 9 is also secured by bolts on dynamic model frame 2, and so design can prevent in knockout course, and the stroke of slide block 4 becomes large due to mechanical oscillation, plays an effect of correcting.Can make to take out block 3 in the process of loosing core moves more accurate simultaneously.
As described in Fig. 5,6, slide block 4 is provided with some mounting grooves 43, is all fixed with snubber block 44 in each described mounting groove 43.Snubber block 44 on slide block 4 is bolted on mounting groove 43, makes passage 7 inwall of the surface of slide block 4 and dynamic model frame 2 form the effect of a damping, above-mentioned anti seismic efficiency can be made in the process of the demoulding more superior.
Lock dog 5 and cover half frame 1 interference fit, its syndeton is simple, and dismounting easily, is assembled convenient for production.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
