Abstract

The utility model relates to a push up demoulding mechanism's improvement structure to one side belongs to the injection mold field. Above -mentioned mechanism mainly comprises oblique top, base, thimble board, movable mold and movable mould board, the bottom mounting of base is in the thimble board, in the top entry movable mould board, the top of base is provided with T shape spout, the bottom on top is provided with the card and establishes the T shape lug in T shape spout to one side, and insert among the movable mold bottom on top to one side, when mould mould close state, the top on top and movable mold's top flush to one side. Through the length that lengthens oblique top, make its top surface when the mould close state with movable mold's top surface parallel and level, still ejecting from the movable mold with the finished piece when the drawing of patterns of bump department is accomplished on the top to one side, so, need not to reserve the through -hole of thimble among the movable mold, guaranteed movable mold's intensity.

Description

The structure-improved of lifter demoulding mechanism
Technical field
The utility model relates to mould of plastics field, particularly relates to a kind of structure-improved of lifter demoulding mechanism.
Background technology
Shown in Fig. 1 is a kind of dark cavity configuration part; the bottom of its inner chamber has salient point 11, and this salient point place needs to use lifter demoulding mechanism to carry out the demoulding, but the appearance requirement of this product is high; do not allow release mark, therefore this product back-off can only be carried out the die cavity of designing mould.After mould die sinking, ejector retainner plate moves ahead, the angle change of oblique top, and make the molding structure in oblique top depart from salient point, last thimble ejects on product dynamic mould core.But dynamic mould core is elongate articles, wherein also will reserve the installing hole of oblique top and the through hole of thimble, the intensity of dynamic mould core is extremely low, very easily damages.
Utility model content
For deficiency of the prior art; the structure of the utility model to lifter demoulding mechanism improves; to make it, not only there is shaping and effect that the is demoulding; also there is the ejecting function of thimble; product just can be ejected from dynamic mould core without the need to thimble by mould; without the need to the through hole of reserved thimble in dynamic mould core, ensure that the intensity of dynamic mould core.
For achieving the above object, the technical solution of the utility model is as follows:
The structure-improved of lifter demoulding mechanism, it forms primarily of oblique top, base, ejector retainner plate, dynamic mould core and moving platen; The bottom of described base is fixed in described ejector retainner plate, and top is inserted in described moving platen; The top of described base is provided with T-shaped chute; The bottom of described oblique top is provided with the T-shaped projection be fastened in T-shaped chute, and the bottom of described oblique top is inserted in described dynamic mould core; When mould mold closing state, the top of oblique top flushes with the top of described dynamic mould core.
Further, the cross section of described oblique top is T-shaped.
Further, described ejector retainner plate is provided with guide rod, and the guide end of described guide rod inserts in described moving platen.
Further, described guide rod is arranged with spring, one end of described spring is connected with described ejector retainner plate, and the other end is connected with described moving platen.
Compared with prior art, the beneficial effects of the utility model are: the length extending oblique top, make its end face when mold closing state and the either flush of dynamic mould core, complete the demoulding at salient point place in oblique top while, also product is ejected from dynamic mould core, so, without the need to the through hole of reserved thimble in dynamic mould core, ensure that the intensity of dynamic mould core.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in prior art and the utility model embodiment, be briefly described to the required accompanying drawing used in prior art and embodiment description below.
Fig. 1 is the structural representation of a kind of plastic part of the prior art;
Fig. 2 is the sectional view of the mould of plastics disclosed in the utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described.
Shown in Fig. 2 is the die cut view of product in production drawing 1, it has cover half A and dynamic model B, be provided with lifter demoulding mechanism in dynamic model, this mechanism primarily of cross section be oblique top C1, the base C2 of T-shaped, ejector retainner plate C3, dynamic mould core C4 and moving platen C5 form; The bottom of base is fixed in ejector retainner plate, and top is inserted in moving platen; The top of base is provided with T-shaped chute; The bottom of oblique top is provided with the T-shaped projection be fastened in T-shaped chute, and the bottom of oblique top is inserted in dynamic mould core; When mould mold closing state, the top of oblique top flushes with the top of dynamic mould core.
Ejector retainner plate is provided with guide rod C6, and the guide end of guide rod inserts in moving platen.Guide rod carries out correcting to the direction of ejector retainner plate.Due to when matched moulds, cover half may damage oblique top, therefore on guide rod, is arranged with spring C7, and one end of spring is connected with ejector retainner plate, and the other end is connected with moving platen, so, just oblique top can be forced to retract by spring force before matched moulds.
Compared with prior art, the beneficial effects of the utility model are: the length extending oblique top, make its end face when mold closing state and the either flush of dynamic mould core, complete the demoulding at salient point place in oblique top while, also product is ejected from dynamic mould core, so, without the need to the through hole of reserved thimble in dynamic mould core, ensure that the intensity of dynamic mould core.
To be apparent for those skilled in the art to the multiple amendment of these embodiments, General Principle as defined herein when not departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, the utility model can not be restricted to these embodiments shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
