Abstract
The utility model provides a core pulling device, which occupies a small space and has a protection function on an oil cylinder. The core pulling device comprises a template, the oil cylinder and a pull rod linked with the output end of the oil cylinder and is characterized in that an accommodating groove is arranged on the template, the oil cylinder is arranged in the accommodating groove and forms guide rail and guide groove matching with the groove wall of the accommodating groove, the other end of the pull rod corresponding to the end part linked with the output end of the oil cylinder is fixed with a mold core arranged on an outer mold, and the outer wall of the oil cylinder is fixed with the mold core arranged on the outer mold. After the technical scheme is adopted, when an injection molding product is formed, the oil cylinder is opened, the pull rod linked with the output end of the oil cylinder is lengthened, and at the time, the pull rod is fixedly connected with the mold core arranged on the mold, so the oil cylinder per se moves in the reverse direction under the counterforce effect of the pull rod. The outer wall of the oil cylinder is fixed with the mold core arranged on the mold, so the oil cylinder drives the mold core to be pulled out when moving outwards, and the core pulling action is realized.
Description
Technical field
The utility model relates to a kind of core-pulling device.
Background technology
In the production of injecting products, many times relate to this step of loosing core, and the mode of loosing core varies, and a kind of mode of loosing core by the flexible realization of oil cylinder pull bar is wherein arranged, and this type of mode of loosing core is mainly used in makes as on the long mould of flute class length.The composition that the tradition cylinder type is loosed core includes the template that is fixed in mould central authorities, and be fixed in oil cylinder on the template, template inside is provided with the containing cavity that fuel feeding cylinder pull bar carries out extensional motion, an end of pull bar and oil cylinder interlock, the other end is fixed with the plate of loosing core, loosing core is fixed with core rod on the plate, and under the normal state, pull bar stretches out in outside the oil cylinder, when oil cylinder drives the pull bar contraction, pull bar drives the core rod return on the plate of loosing core, and core rod will spin off from injecting products this moment, thus the work step that realization is loosed core.Then, the cylinder type that traditional cylinder type is loosed core is arranged on the template, and cylinder body protrudes from die surface all the time, causes entire length longer thus, and it is big to take up room, even and when normal state, also cause damage to stretching out the outer cylinder body of mould easily.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of and has taken up room for a short time, and oil cylinder is had the core-pulling device of defencive function.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of core-pulling device, the pull bar that includes template, oil cylinder and link with the oil cylinder output, it is characterized in that: described template is provided with storage tank, oil cylinder is installed in storage tank and is constituted the guide rail guide groove with the storage tank cell wall and cooperates, fix with the other end of oil cylinder output interlock end and the die on the outer mold on the pull bar, the core rod on oil cylinder outer wall and the outer mold is fixed.
Adopt technique scheme, after the injecting products moulding, open oil cylinder, to extend with the pull bar of oil cylinder output interlock,, so oil cylinder self will under the reaction force of pull bar counter motion again because of core rod oil cylinder outer wall and mould on fix because pull bar is fixedlyed connected with the die on the mould this moment, then when oil cylinder outwards moves, will drive core rod and extract out, thereby realize loosing core action.
Of the present utility modelly further be set to: described tie rod end also is provided with connector, and an end and the pull bar of this connector are fixed, and the other end and outside die are fixed, and is provided with the boss of annular on the connector with the fixing end perisporium of outside die.
Adopt technique scheme, cumbersome because of the pull bar replacing, so the setting of tie rod end connector has then avoided pull bar to wear and tear because of often moving, prolonged the service life of this core-pulling device relatively.
Of the present utility modelly further be set to: the place, end of described oil cylinder output is provided with a plate again, one end and the oil cylinder outer surface of connecting plate are fixed, core rod on the other end and the outer mold is fixed, be provided with symmetrically on the storage tank cell wall and the axial corresponding to guide groove of storage tank, the oil cylinder sidewall is provided with the slide block suitable with guide groove.
Adopt technique scheme, cause does not have good technology that core rod is fixed on the oil cylinder, and ought the different moulds of use be core rod will be taken off from oil cylinder, must will cause damage to oil cylinder, fixedly a plate has then well solved this problem on the oil cylinder surface.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings
Fig. 1 is the schematic diagram of the utility model embodiment.
Fig. 2 is the installation diagram of the utility model embodiment, mould and injecting products.
Fig. 3 is the structural representation of the utility model embodiment, mould and injecting products.
The specific embodiment
As shown in Figure 1, 2, 3, the pull bar 3 that present embodiment includes template 1, oil cylinder 2 and links with oil cylinder 2 outputs, template 1 is fixed in mould 4 central dies 41 and core rod 42 positions, and be provided with a storage tank 11 with relative position, die 41 positions on the template 1, oil cylinder 2 is installed in storage tank 11, be provided with symmetrically on storage tank 11 cell walls and storage tank 11 axial corresponding to guide grooves 111, oil cylinder 2 sidewalls are provided with the slide block suitable with guide groove 111, constitute described guide rail guide groove thus and cooperate.The other end with oil cylinder 2 outputs interlock end on the pull bar 3 is provided with a connection piece 31, one end of this connector 31 and pull bar 3 are fixing, the other end and die 41 are fixing, the end perisporium of fixing with die 41 on the connector 31 is provided with the boss 311 of annular, then die 41 is provided with and the suitable groove of this boss 311 shapes, realizes that thus connector 31 and die 41 are in spacing cooperate of connector 31 on axially.The place, end of oil cylinder 2 outputs is provided with a plate 5, and a side of connecting plate 5 and oil cylinder 2 outer surfaces are fixed, and the core rod 42 on opposite side and the mould 4 is fixing.
In the utility model, after injecting products 6 moulding, open oil cylinder 2, to extend with the pull bar 3 of oil cylinder 2 outputs interlock,, so oil cylinder 2 self will under the reaction force of pull bar 3 counter motion again because of core rod oil cylinder 2 outer walls and mould 4 on 42 fix because pull bar 3 is fixedlyed connected with the die 41 on the mould 4 this moment, then when oil cylinder 2 outwards moves, will drive core rod 42 and extract out, thereby realize loosing core action.Wherein, cumbersome because of pull bar 3 replacings, so pull bar 3 ends are provided with a connection piece 31, then this connector 3 can avoid pull bar 3 to wear and tear because of often moving, and has prolonged the service life of this core-pulling device relatively.In addition, because of there being good technology core rod 42 is not fixed on the oil cylinder 2, and when using different moulds to be, core rod 42 is taken off from oil cylinder 2, must will cause damage to oil cylinder 2, fixedly a plate 5 has then well solved this problem on oil cylinder 2 surfaces.The utility model can also have other embodiments, and the technical scheme that equal replacement of all employings or equivalent transformation form all drops within the claimed scope of the utility model.
