Description
Technical field
The utility model relates to one and pushes away pearl formula Double-ejection injection mold, belongs to injection mold ejecting mechanism technical field.
Background technology
Injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.Dynamic model and cover half closed formation running gate system and die cavity in the time of injection moulding, when die sinking, dynamic model separates to take out plastic products with cover half.
In die sinking process, need to there is ejecting mechanism that plastic products and the solidifying material in runner thereof are released or pull-out.Release fixed head and push pedal in order to clamp push rod.In push rod, be generally also fixed with release link, release link resets push pedal in the time of moving, cover half matched moulds.But usually there will be plastic to be difficult to the complete demoulding or can not free-falling situation.
Utility model content
Object: in order to overcome the deficiencies in the prior art, the utility model provides one to push away pearl formula Double-ejection injection mold.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
One pushes away pearl formula Double-ejection injection mold, comprises core, moving plate, push rod, top board, top plate guide post, also comprises push rod, sleeve, ball, edge cover, push piece plate, on described top board, is provided with top plate guide post; Described push rod is arranged on top board, and push rod movable sleeving is connected in moving plate and core.Described push rod is arranged on top board, and push rod front portion is provided with sleeve, and barrel forward end is provided with around the push rod ball of a week.Described push rod front portion, sleeve, ball movable sleeving are connected in edge cover; Described push rod free end and push piece plate mobile link.
Described edge cover end is provided with one week reaming groove, crosses ball for push rod front end.
Described edge cover, sleeve and push rod adopt the processing of hardening, for increasing anti-wear performance.
Also comprising release link, on described top board, be provided with release link, after driving push rod, move, is the reset vacating space of ball.
The half of described ball diameter d equals the diameter c of reaming groove.
Beneficial effect: what the utility model provided pushes away pearl formula Double-ejection injection mold, and having stable behavior is reliable, freely, stripping result is good, without dead point, hard spot and twisted phenomenon in operation.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the partial structurtes schematic diagram of the utility model I portion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, one pushes away pearl formula Double-ejection injection mold, comprises core 1, moving plate 6, push rod 9, top board 11, top plate guide post 10, also comprises push rod 7, sleeve 5, ball 4, edge cover 3, push piece plate 2, on described top board 11, is provided with top plate guide post 10; Described push rod 9 is arranged on top board 11, and push rod 9 movable sleevings are connected in moving plate 6 and core 1.Described push rod 7 is arranged on top board 11, and push rod 7 front portions are provided with sleeve 5, and sleeve 5 front ends are provided with around the push rod ball of 7 one weeks 4.Described push rod 7 front portions, sleeve 5, ball 4 movable sleevings are connected in edge cover 3; Described push rod 7 free ends and push piece plate 2 mobile links.
As shown in Figure 2, described edge overlaps 3 ends and is provided with one week reaming groove 12, crosses ball 4 for push rod 7 front ends.
Described edge cover 3, sleeve 5 and push rod 7 adopt the processing of hardening, for increasing anti-wear performance.
Also comprising release link 8, on described top board 11, be provided with release link 8, after driving push rod 7, move, is the reset vacating space of ball 4.
The half of described ball 4 diameter d equals the diameter c of reaming groove 12.
Detailed description of the invention is as follows: sleeve 5 is arranged on push piece plate 2, slides, and in uniform through hole, place ball 4 in edge cover 3 on circumference.Push rod 7 is fixed on top board 11, in edge cover 3, slides.In ejection process, push rod 7 promotes ball 4, sleeve 5, push piece 2 and plastic is pushed up to release core 1 together with push rod 9.In the time that ball 4 is pulled to reaming groove 12 place, push rod 7 promotes after ball 4 moves outward to cross, thereby has lost the effect that ejects to sleeve 5, sleeve 5 and push piece plate 2 is stopped mobile.10 promotion push rods 9 of top plate guide post, have continued to eject for the second time action.
For making push rod 7 cross ball 4, at edge cover 3 ends, reaming groove 12 is set, dimensional requirement as shown in Figure 2, i.e. c=d/2.For strengthening anti-wear performance, the processing of all should hardening of edge cover 3, sleeve 5 and push rod 7.
Also being provided with after release link 8 drives push rod 7 and moving, is the reset vacating space of ball 4, to prevent that interference is each other moved in the time resetting.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; do not departing under the prerequisite of the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
