Abstract
The utility model discloses an ejection mechanism for an injection mold, which comprises an ejector pin (2), an ejector pin fixing plate (3) and an ejector pin plate (4), wherein, the ejector pin plate (4) is firmly connected with an injection molding machine pull rod (5). Due to the adoption of technical scheme, linkage between the ejector pin plate and the injection molding machine pull rod is realized; by taking the advantages of the compulsory ejection reposition mechanism for the mold, the problem concerning collision between the ejection mechanism and a core-pulling mechanism as well as damage to mold due to performance of mold closing with incomplete reposition of the ejector pin is effectively solved; and the mold closing is guaranteed of execution after complete reposition of the ejector pin, thereby avoiding accidents, preventing the mold from being damaged, and ensuring smooth proceeding of injection molding production.
Description
Technical field
The utility model belongs to the technical field of plastic product technological equipment for making, relates to the structure of injection mold, and more particularly, the utility model relates to a kind of ejecting mechanism of injection mold.
Background technology
At present, injection mold generally uses spring to realize resetting earlier of ejecting mechanism, but produces medi-spring in case lost efficacy (for example, spring is stuck), and ejecting mechanism just can't be realized resetting earlier.In the actual production, material jacking mechanism will occur and not reset with regard to the phenomenon of matched moulds, core-pulling mechanism and thimble interfere.If core-pulling mechanism and thimble are interfered, mould is matched moulds under the situation that thimble does not reset fully, directly causes mould thimble and slide block to bump against and damages.
Shown in Figure 1 as in this Figure of description is the matched moulds state after spring 6 lost efficacy, and the slide block 1 interference impact site 7 shown in the figure of loosing core in the thimble 2 on the mould in the ejecting mechanism and the core-pulling mechanism bumps against, and causes the mould damage.
The utility model content
At the described defective of background technology, problem to be solved in the utility model provides a kind of ejecting mechanism of injection mold, its objective is to avoid because the unexpected ejecting mechanism of injection mold and the accident that core-pulling mechanism bumps of causing.
To achieve these goals, the technical scheme taked of the utility model is:
The ejecting mechanism of this injection mold provided by the utility model comprises thimble, thimble fixed head and ejector retainner plate, and described ejector retainner plate and injection machine pull bar are fastenedly connected.
For making the utility model more perfect, more detailed and concrete technical scheme below also further having proposed, to obtain best practical function, realize goal of the invention better, and improve novelty of the present utility model and creativeness:
Described ejector retainner plate with the injection machine pull bar mode of being fastenedly connected is: the central authorities of described ejector retainner plate are connected with the end of injection machine pull bar.
Described ejector retainner plate and injection machine pull bar fastening structure are: the central authorities of described ejector retainner plate are screwed hole; The termination of described injection machine pull bar is an external screw thread, and promptly pull rod screw 9, and described screwed hole forms spiral with external screw thread and cooperates.
The screw thread specification that described spiral cooperates is the closely-pitched regular screw threads of M12.
The utility model adopts technique scheme, realize the interlock of ejector retainner plate and injection machine pull bar, utilize mould to eject Compulsory reduction mechanism, effectively solved because of the problem that mould matched moulds under the situation that thimble does not reset fully causes that ejecting mechanism and core-pulling mechanism bump, mould damages, guaranteed that ejector retainner plate could matched moulds after resetting fully, prevent the generation of contingency, avoided the damage of mould, injection moulding is produced carry out smoothly.
Description of drawings
Below expressed content of each width of cloth accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is the schematic diagram of the described structure of this specification background technology part;
Fig. 2 is a structural representation of the present utility model.
Be labeled as among the figure:
1, the slide block of loosing core, 2, thimble, 3, the thimble fixed head, 4, ejector retainner plate, 5, the injection machine pull bar, 6, spring, 7, interfere impact site, 8, the mould die joint, 9, pull rod screw.
The specific embodiment
Contrast accompanying drawing below, by description to embodiment, to effect and operation principle, the manufacturing process of the mutual alignment between the shape of the specific embodiment of the present utility model such as related each member, structure, the each several part and annexation, each several part and manipulate method etc., be described in further detail, inventive concept of the present utility model, technical scheme had more complete, accurate and deep understanding to help those skilled in the art.
The of the present utility model structure expressed as Fig. 2 is a kind of ejecting mechanism of injection mold, comprises thimble 2, thimble fixed head 3 and ejector retainner plate 4.When mold injection, the ejector retainner plate 4 in the ejecting mechanism resets earlier under the effect of spring 6, then could matched moulds, and form mould die joint 8.
In order to solve the problem that exists at the described present known technology of this specification background technology part and to overcome its defective, realization is avoided because accident causes the ejecting mechanism of injection mold and the goal of the invention that core-pulling mechanism bumps, and the technical scheme that the utility model is taked is:
As shown in Figure 2, the ejecting mechanism of this injection mold provided by the utility model, described ejector retainner plate 4 is connected with injection machine pull bar 5.
Technique scheme of the present utility model is to have adopted mould to eject Compulsory reduction mechanism, because ejector retainner plate 4 and injection machine pull bar 5 are fastenedly connected, realizes the interlock of ejector retainner plate 4 and injection machine pull bar 5, has guaranteed that ejector retainner plate could matched moulds after resetting fully.Solved effectively because of the problem that mould matched moulds under the situation that thimble does not reset fully causes that ejecting mechanism and core-pulling mechanism bump, mould damages, guaranteed that ejector retainner plate could matched moulds after resetting fully, prevent the generation of contingency, avoided the damage of mould, injection moulding has been produced carry out smoothly.
Below be concrete exemplifying embodiment of the present utility model, select for use for those skilled in the art's reference when implementing the utility model:
Embodiment one:
Embodiment two:
Embodiment three:
The screw thread specification that spiral described in the utility model cooperates is the closely-pitched regular screw threads of M12.Adopt the closely-pitched regular screw threads of M12, can satisfy the force request of forced resetting.
Production practices prove: in the mould of M005BYD, adopt this utility model technology, through overtesting, result of use is fairly obvious, thimble and slide block does not take place bump against, and mould production is very smooth.
In conjunction with the accompanying drawings the utility model has been carried out exemplary description above; obviously the utility model specific implementation is not subjected to the restriction of aforesaid way; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or design of the present utility model and technical scheme are directly applied to other occasion without improving, all within protection domain of the present utility model.
