Abstract

The utility model provides a mechanical long core-pulling mechanism, which comprises a guide rack (1), guide strips (2), a slide block (3), a copper sleeve (4), a long core-pulling element (5) and a spading machine (6), wherein the guide rack (1) is fastened on a panel through a screw; the copper sleeve (4) is fixedly connected with the guide rack (1); a rack part of the guide rack (2) is meshed with the guide rack (1); the convex parts of the guide strips (2) are attached to the surface of a product; the guide strips (2) are fastened to two sides of the slide block; the inner surface of the slide block (3) is fastened with the surface of the long core-pulling element (5); and the spading machine (6) is fastened to a plate A. The mechanism has a reasonable and reliable structure, avoids damaging a die and a product, reduces cost and improves production efficiency.

Description

The long core-pulling mechanism of a kind of mechanical type
Technical field
The utility model relates to Mould Machining, particularly the long core-pulling mechanism of a kind of mechanical type of injection mold.
Background technology
For the long through-hole of plastic product, need long usually apart from side core-pulling.Side core-drawing mechanism commonly used has hydraulic pressure to loose core, taper pin is loosed core and the rack-and-pinion core-pulling mechanism.Hydraulic pressure is loosed core needs external oil cylinder, add oil circuit, and die cost height and molding cycle are long.Conventional taper pin side core-drawing mechanism inclination angle is 22 degree to the maximum, for satisfying required loosing core apart from adopting long taper pin, not only increases die size, and the rigidity of long taper pin, intensity, robust motion is not good enough, the poor stability of mould.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art a kind of simple in structure, safety and stability, saving cost, the short long core-pulling mechanism of mechanical type of molding cycle is provided.
Technical solutions of the utility model are as follows: the long core-pulling mechanism of a kind of mechanical type, comprise guiding tooth bar 1, gib block 2, slide block 3, copper sheathing 4, long loose core part 5, shovel machine 6, it is characterized in that described guiding tooth bar 1 usefulness screw is anchored on the panel, the other end is located in the die cavity of back mould, copper sheathing 4 is fixedlyed connected with guiding tooth bar 1, the tooth bar position of gib block 2 and 1 engagement of guiding tooth bar, gib block 2 is fastened on the both sides of slide block, the inner surface of slide block 3 and long the surperficial fastening of part 5 of loosing core, shovel machine 6 is anchored on the A plate.
During die sinking, guiding tooth bar 1 drives the tooth-strip part displacement of the gib block 2 on the slide block 3 and moves, and makes the long part 5 of loosing core slip off at leisure and realizes loosing core.
The tooth-strip part displacement of the gib block 2 during matched moulds on the guiding tooth bar 1 drive slide block 3 is moving, pins slide block 3 by the shovel machine at last.
After adopting such scheme, the utility model has following advantage: the realization of this reliable in structure the action of loosing core of mechanical type length, stability was high when it was produced than (hydraulic pressure) oil cylinder in the past, and is practical and safety coefficient is high, can move the successful shortening production cycle by disposable realization folding mould again.
Description of drawings
Fig. 1 is the stereogram of the utility model structure;
Fig. 2 is the structural representation of the utility model structure.
The specific embodiment
In order better to understand the utility model content, the utility model is further specified below in conjunction with accompanying drawing.
Consult accompanying drawing 1,2, the utility model relates to the long core-pulling mechanism of a kind of mechanical type, comprise guiding tooth bar 1, gib block 2, slide block 3, copper sheathing 4, long loose core part 5, shovel machine 6, described guiding tooth bar 1 usefulness screw is anchored on the panel, and the other end is located in the die cavity of back mould, and copper sheathing 4 is fixedlyed connected with guiding tooth bar 1, the tooth bar position of gib block 2 and 1 engagement of guiding tooth bar, gib block 2 is fastened on the both sides of slide block, the inner surface of slide block 3 and long the surperficial fastening of part 5 of loosing core, and shovel machine 6 is anchored on the A plate.
During die sinking, guiding tooth bar 1 drives the tooth-strip part displacement of the gib block 2 on the slide block 3 and moves, and makes the long part 5 of loosing core slip off at leisure and realizes loosing core.
The tooth-strip part displacement of guiding tooth bar 1 drive slide block 3 and gib block 2 is moved during matched moulds, pins slide block 3 by the shovel machine then.
After adopting such scheme, the utility model has following advantage: the realization of this reliable in structure the action of loosing core of mechanical type length, stability was high when it was produced than (hydraulic pressure) oil cylinder in the past, and is practical and safety coefficient is high, can move the successful shortening production cycle by disposable realization folding mould again.
Embodiment only is a preferred optimum implementation of the present utility model in sum; unintelligible is that protection domain of the present utility model is limited; for adjustment that does not exceed technical solutions of the utility model and the change that the technical work personnel of this area do according to the utility model, should think and drop in the protection domain of the present utility model.
