Abstract
The invention discloses a push ball type double-ejection injection mold. The double-ejection injection mold comprises a core, a movable plate, an ejection rod, an ejection plate and an ejection plate guide pillar, and further comprises a push rod, a sleeve, balls, a bushing and a push plate, wherein the ejection plate guide pillar and the ejection rod are arranged on the ejection plate; the ejection rod is movably sleeved with the movable plate and the core; the push rod is arranged on the ejection plate; the sleeve is arranged at the front part of the push rod; a circle of the balls are arranged at the front end of the sleeve and around the push rod; the front part of the push rod, the sleeve and the balls are movably sleeved with the bushing; the free end of the push rod is movably connected with the push plate. The double-ejection injection mold is stable and reliable in action, smooth in movement, good in demoulding effect, and free of the phenomena of dead points, hard points and distortion.
Description
Technical field
The present invention relates to a kind of pearl formula Double-ejection injection mold that pushes away, belong to injection mold ejecting mechanism technical field.
Background technology
Injection mold is comprised 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 when injection moulding, during die sinking, dynamic model is separated with cover half to take out plastic products.
In die sinking process, need to there is ejecting mechanism that plastic products and the solidifying material in runner thereof are released or pulled 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 when moving, cover half matched moulds.But usually there will be plastic to be difficult to the complete demoulding or can not free-falling situation.
Summary of the invention
Object: in order to overcome the deficiencies in the prior art, the invention provides a kind of pearl formula Double-ejection injection mold that pushes away.
Technical scheme: for solving the problems of the technologies described above, the technical solution used in the present invention is:
Push away a pearl formula Double-ejection injection mold, comprise core, moving plate, push rod, top board, top plate guide post, also comprise push rod, sleeve, ball, edge cover, push piece plate, on described top board, be 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, for push rod front end, crosses ball.
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.
Half of described ball diameter d equals the diameter c of reaming groove.
Beneficial effect: the pearl formula Double-ejection injection mold that pushes away provided by the invention, having stable behavior is reliable, and freely, stripping result is good, without dead point, hard spot and twisted phenomenon in operation.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the partial structurtes schematic diagram of I of the present invention portion.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
As shown in Figure 1, a kind of pearl formula Double-ejection injection mold that pushes away, 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, for push rod 7 front ends, crosses ball 4.
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.
Half of described ball 4 diameter d equals the diameter c of reaming groove 12.
The specific embodiment 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 promotion balls 4, sleeve 5, push piece 2 push up plastic release core 1 together with push rod 9.When ball 4 is pulled to reaming groove 12 place, after moving outside push rod 7 promotion balls 4, cross, thereby lost the effect that ejects to sleeve 5, sleeve 5 and push piece plate 2 are 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 when resetting.
The above is only the preferred embodiment of the present invention; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
