Abstract
The utility model provides an ejecting mechanism for avoiding the interference of a mould slant-ejecting guide rod, comprising a slant ejector (1), an ejecting block (2), a guide rod (3), a slant-ejecting guide rod (4), an ejecting block guide rod (5), a mould core (6), an oil cylinder (7), an ejecting-rod fixing plate (8), a pushing plate (9), a soleplate (10) and the like; the guide rod (3) penetrates through the ejecting block (2) to be inserted into the slant ejector (1), and the rod diameter of the guide rod (3) are in clearance fit with the hole diameters of the slant ejector (1) and the ejecting block (2); the slant-ejecting guide rod (4) does not need to be fixed on the ejecting-rod fixing plate (8), and the extended length thereof only needs to be more than the ejecting stroke of the mould and the slant-ejecting guide rod (4) will not collide with the guide rod (5). In the structure, the slant ejector (1) and the ejecting block (2) can be ejected out in the mold core (6) at the same time, thus avoiding the interfered colliding between the slant-ejecting guide rod (4) and the ejecting block guide rod (5) during the process of using the mould; the utility model has the advantages of simple structure, convenient manufacturing, improving the safe reliability and the production efficiency of the mould.
Description
Technical field
The utility model relates to a kind of ejecting mechanism that prevents that the oblique top guide post from interfering in the injection mold, specifically, provides a kind of ejecting mechanism that prevents mould oblique top guide post and jacking block guide post interference and collision of practicality for the security reliability that improves mould.
Background technology
Plastics injection mould generally comprises parts such as moulding section, guiding mechanism, ejecting mechanism at present, Figure 1 shows that the bumper injection mold, because jacking block and oblique top is adjacent and volume is very little, but still the little and length of diameter long oblique top guide post and jacking block guide post will be set respectively thereon, so that the two all will be fixed on the push rod fixed head; When the demoulding or matched moulds; oblique top guide post and jacking block guide post are through the phenomenon of regular meeting's interference and collision; common way is to solve by the diameter that reduces the oblique top guide post; but owing to reduce diameter; make the intensity of oblique top guide post reduce; thereby the phenomenon that the oblique top guide post ruptures can take place in process of production, and cause mould normally not use, influenced productivity ratio.For this reason, need the new construction of a kind of practicality of innovative design, prevent oblique top guide post and jacking block guide post interference and collision problem, improve the security reliability and the productivity ratio of mould.
Summary of the invention
The purpose of this utility model provides and a kind ofly can solve oblique top guide post and jacking block guide post interference and collision problem in the mould production process better, guarantees the later stage ordinary production of mould effectively.For reaching above-mentioned purpose, the utility model adopts a kind of ejecting mechanism that prevents that mould oblique top guide post from interfering, it is made up of jacking block, oblique top, guide post, oblique top guide post, jacking block guide post, core, oil cylinder, push rod fixed head, push pedal, base plate etc., guide post of design between oblique top and jacking block, be that guide post passes jacking block and is inserted in the oblique top, and the aperture of the shank diameter of guide post and jacking block, oblique top constitutes matched in clearance, and guide post can be horizontally disposed, also can be in tilted layout; The diameter of oblique top guide post needn't reduce and length can shorten, and need not to be fixed on the push rod fixed head, but its extension elongation must be greater than the mould ejection stroke, and does not collide with guide post.
After mould is finished the product injection moulding, eject the upwards action of push rod fixed head of actuator cylinder driving jacking block guide post, move upward by the jacking block guide post that is threaded with push pedal thereby drive, the jacking block guide post forces fixing with it jacking block also to move upward, also drive the oblique top that cooperates with it by guide post simultaneously and moved upward together, thereby prevented the phenomenon of oblique top guide post and jacking block guide post interference and collision.This ejecting mechanism is simple in structure, easily manufactured, can guarantee the later stage ordinary production of mould.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described.
Accompanying drawing 1 is the three-dimensional analysis of the overall structure sketch that existing mold oblique top guide post and jacking block guide post are interfered
Accompanying drawing 2,3 is respectively overall structure figure of the present utility model and partly cuts open the structure enlarged drawing
Wherein: 1-oblique top; 2-jacking block; 3-guide post; 4-oblique top guide post; 5-jacking block guide post; 6-core;
7-oil cylinder; 8-push rod fixed head; 9-push pedal; 10-base plate;
Accompanying drawing 4 is the three-dimensional analysis of an overall structure of the present utility model sketch.
The specific embodiment
Fig. 2,3 can be used as an embodiment of the present utility model, it is made up of oblique top 1, jacking block 2, guide post 3, oblique top guide post 4, jacking block guide post 5, core 6, oil cylinder 7, push rod fixed head 8, push pedal 9, base plate 10 etc., guide post 3 of design between oblique top 1 and jacking block 2, be that guide post 3 passes jacking block 2 and is inserted in the oblique top 1, and the aperture of the shank diameter of guide post 3 and jacking block 2, oblique top 1 constitutes matched in clearance, guide post 3 can be horizontally disposed, also can be in tilted layout.The oblique top guide post 4 of oblique top 1 is shortened greatly, need not to be fixed on the push rod fixed head 8, and its extension elongation L only must get final product greater than mould ejection stroke H, and does not collide with jacking block guide post 5, and Fig. 4 is the three-dimensional analysis of an overall structure of the present utility model sketch.
After mould is finished the product injection moulding, eject the upwards action of push rod fixed head 8 of actuator cylinder 7 driving jacking block guide posts 5, move upward by the jacking block guide post 5 that is threaded with push pedal 9 thereby drive, jacking block guide post 5 forces fixing with it jacking block 2 also to move upward; Jacking block 2 drives oblique top 1 together by guide post 3 and also moves upward together in motion, so just with the release core 6 in moulding 11 tops, oblique top guide post 4 and jacking block guide post 5 can interference and collisions in the whole process, and the mould matched moulds process after moulding 11 ejects can not produce the interference and collision phenomenon yet.This ejecting mechanism is simple in structure, easily manufactured, can guarantee the later stage ordinary production of mould, has improved the security reliability and the productivity ratio of mould.
