Abstract
The utility model relates to the field of injection molding, in particular to an inner column core-pulling mechanism and an injection mold. The inner column core-pulling mechanism is used for demolding an annular plastic part with an inwards back-off function and comprises a shrinkage locking block and six tapered wedge type inner columns connected with the shrinkage locking block; under an assembling state of the mode, the shrinkage locking block is in tight contact with the six tapered wedge type inner columns; the six tapered wedge type inner columns are uniformly distributed at the periphery of the shrinkage locking block; under an opening state of the mode, the shrinkage locking block is separated from the six tapered wedge type inner columns. Therefore, the inner column core-pulling mechanism occupies a small space; when the annular side wall of an injection molded product is slightly inwards backed off, the inner column core-pulling mechanism still can successfully demold a product; the application range is large.

The accompanying drawing explanation
Fig. 1 is the perspective view of line position core-pulling mechanism in the utility model;
Fig. 2 is under the matched moulds state, and in six Wedge types, line position contracting Ke shovels the top view of base and the cooperation of annular plastic;
Fig. 3 is under the matched moulds state, and in six Wedge types, line position, contracting Ke shovel the top view of base and the cooperation of annular plastic.
The specific embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Embodiment mono-
As shown in FIG. 1 to 3, the present embodiment provides a kind of interior line position core-pulling mechanism 100, be used to having annular plastic 200 demouldings of interior back-off, interior line position core-pulling mechanism 100 comprise contracting Ke shovel base 10 and with line position 20 in contracting Ke shovels six Wedge types that base 10 is connected.Contracting Ke shovels base 10 and six interior line position close contacts of Wedge type 20 under mould matched moulds state, and six interior line positions 20 of Wedge type are evenly distributed on the periphery that contracting Ke shovels base 10; Contracting Ke shovels line position 20 in six Wedge types of base 10 disengagings under die opening state.The present embodiment dwindles interior line position core-pulling mechanism and takes up room, and back-off hour still can complete product stripping, applied range smoothly in the injecting products annular sidewall.
Fig. 2 is under the matched moulds state, and in six Wedge types, line positions shovel with contracting Ke the top view that basigamy closes, and six interior line positions 20 of Wedge type are shoveled on the axial direction of base 10 symmetrical contracting Ke.And as shown in Figure 2, under the matched moulds state, in six Wedge types, the end face of line positions 20 and end face that contracting Ke shovels base 10 are spliced to form and the circle of annular plastic 200 adaptations or oval.Obviously, when the demoulding, contracting Ke shovels the interior line position 20 of 20, six Wedge types of line position in six Wedge types of base 10 disengagings and against the area formed, is less than the area that annular plastic 200 sidewalls surround after resetting.
Preferably, interior line position core-pulling mechanism also comprises with contracting Ke and shovels the panel that base 10 is connected, in panel and Wedge type, be provided with guide rail 21 between line position 20, this guide rail forms certain angle with the axial direction that contracting Ke shovels base 10, this guide rail 21 shovels base 10 be used to contracting Ke and breaks away from Wedge types after line position 20, contracting Ke shovels base 10 and drives line position 20 in Wedge type again and exit along this guide rail the space that annular plastic 200 sidewalls surround, and guarantees that annular plastic 200 can the smooth demouldings.
When matched moulds, contracting Ke shovels base 10 and moves along directions X in Fig. 1, and insert between six Wedge types 20, contracting Ke shovels base 10 and six interior line position close contacts of Wedge type 20, in six Wedge types, the end face of line positions 20 and end face that contracting Ke shovels base 10 are spliced to form and the circle of annular plastic 200 adaptations or oval, thereby can injection moulding form annular plastic 200; When die sinking, along directions X in Fig. 1, move in the other direction, contracting Ke shovels base 10 and breaks away from line position 20 in six Wedge types, in six Wedge types, line position 20 contacts, the face that in six Wedge types, line position 20 end faces are spliced to form is less than the limit that the sidewall of annular plastic 200 surrounds, and contracting Ke shovels base 10 and drives line position 20 in six Wedge types again and also along directions X, move in the other direction, realizes that in six Wedge types, line position 20 breaks away from annular plastic 200, thereby realizes smoothly the demoulding.
Embodiment bis-
The present embodiment provides a kind of injection mold, for having the injection moulding of annular plastic of interior back-off, it comprises dynamic model and cover half, between dynamic model and cover half, be provided with the interior line position core-pulling mechanism for the demoulding, interior line position core-pulling mechanism comprise contracting Ke shovel base and with line position in contracting Ke shovels six Wedge types that base is connected, contracting Ke shovels line position close contact in base and six Wedge types under mould matched moulds state, and in six Wedge types, line position is evenly distributed on the periphery that contracting Ke shovels base, contracting Ke shovels line position in six Wedge types of base disengaging under die opening state.
In six Wedge types, line position is shoveled on the axial direction of base symmetrical contracting Ke.
In six Wedge types, the end face of line positions and end face that contracting Ke shovels base are spliced to form and the circle of annular plastic adaptation or oval.
