Description

Has the slide block mould emptier of loosing core for twice
Technical field
The utility model relates to a kind of slide block mould emptier of loosing core for twice that has.
Background technology
Along with the development of car industry, the function of automobile is more and more advanced, and the moulding product structure in the automobile becomes increasingly complex, thereby causes conventional mould structure design can not satisfy existing moulding.In common injection mold structure, slide block is loosed core can only be toward a direction demoulding.As run into the product structure complexity, the structure that twice slide block of need loosed core, usually way is for being put into the demoulding of loosing core of conventional slide block with the inserts mold insert earlier, separate with plastic with artificial follow-up disengaging inserts mold insert again, mode of operation not only need increase manually-operated like this, can not adapt to fully-automatic production, also can produce, reduce product percent of pass owing to manually-operated reason can reduce the plastic dimensional accuracy.
The utility model content
For overcoming the above-mentioned shortcoming of prior art; the utility model provides a kind of twice of two different directions of can realizing in knockout course to loose core; adapt to fully-automatic production, save manually, reduce production costs, improve the slide block mould emptier of loosing core for twice that has of plastic dimensional accuracy.
Has the slide block mould emptier of loosing core for twice, comprise solid plate with cover half benevolence, moving platen with mavable module core, the transversely movable slide block that is installed on the moving platen, be connected, drive during die sinking the oil cylinder of slide block away from die with slide block, with latch segment affixed with solid plate, that slide block is compressed to die when the matched moulds state, and between oil cylinder and slide block, the block of restriction slide block lateral displacement;
Described latch segment cooperates with slide block by the inclined-plane, and during the matched moulds state, solid plate, moving platen and slide block are enclosed the plastic die cavity;
It is characterized in that: described slide block comprises master slider that compresses plastic and the side slide that is slidably mounted on the described master slider, realization plastic feature holes is loosed core, and described master slider is connected with described oil cylinder;
Described solid plate is provided with and makes the Angle Pin of side slide away from die when die sinking, is provided with between described master slider and the side slide to stop master slider to follow the spring that side slide slides;
Described master slider is provided with the mold insert of moulding plastic feature holes, side slide during away from die, drives described mold insert and breaks away from the plastic feature holes.
Further, affixed one allows mold insert to vertically move, limit the press strip that mold insert laterally moves on the described master slider, described mold insert slidably is connected with described press strip by the mold insert seat, described mold insert seat is provided with the guide groove of inclination, and described side slide is provided with and guiding raised line in described guide groove cooperates, slides on described guide groove;
Described side slide is made up of the affixed portion of loosing core of sliding part and tail end and sliding part, and the described portion of loosing core stretches into the plastic die cavity, and described raised line is arranged at the front end of the portion of loosing core; Described sliding part is connected with described latch segment.
Further, be connected with the slider guide that the guiding side slide laterally moves on the described master slider, described slider guide is provided with the limited screw of constrained side slide block lateral displacement.
Further, described press strip is the spacing raised line that longitudinally is provided with, and described mold insert seat is provided with the limited impression that cooperates with described spacing raised line.
Technical conceive of the present utility model is: when moving platen and solid plate die sinking, latch segment leaves side slide gradually, and side slide laterally moves under the effect of Angle Pin, gradually away from plastic.At this moment, master slider is not followed the side slide motion under the effect of spring; And the mold insert seat vertically moves, breaks away from gradually the plastic feature holes under side slide is loosed core the effect of guiding raised line of portion.When side slide arrived limited screw, mold insert broke away from the plastic feature holes fully, finished to loose core for the first time.
At this moment, cylinder action, drive master slider laterally move, away from plastic, when master slider arrived block, master slider broke away from plastic fully, finished to loose core for the second time.Plastic can break away from mould fully.
Like this, in a die sinking, finish respectively that the plastic feature holes is loosed core and plastic is loosed core, make the smooth demoulding of product, need not manually to carry out the plastic feature holes and loose core, be suitable for automated production, save human cost, improve production efficient, reduce production costs.
Because the guide groove on the mold insert seat is obliquely installed, when the portion of loosing core of side slide horizontal when mobile, the guiding raised line slide with guide groove within and order about guide groove and be along the longitudinal movement, mold insert breaks away from the plastic feature holes.Guide groove that tilts and the guiding cord tissue that cooperates with guide groove have simple in structure, mechanism's little advantage that takes up room.
The utlity model has twice of can in knockout course, realize two different directions and loose core, adapt to fully-automatic production, save artificial, reduce production costs, improve the plastic dimensional accuracy.
