Description
Technical field
The utility model relates to easy open cover manufacturing technology field, relates in particular to a kind of counterdie core rod buffer gear of basic lids of easy open lids.
Background technology
In basic lids of easy open lids molding procedure, sheet material mobility is most important, only in this way guarantee shape of product and size; Existing mold structure is that lower mold core is fixedly connected with die shoe, mould is final molding capel in closing course, because capel is the most concentrated place of easy open cover stress, as last procedure processing, and sheet material is carried out to rigidity extruding, be unfavorable for like this flow-drawing moulding of sheet material; First due to rigidity extruding, cause sheet material poor fluidity, in forming process, lid easily ftractures, and causes functional defect, on lid capel, cracks, and even causes quick-fried lid, affects product quality; Secondly, upper and lower core rod rigid stamp is larger to mould and board impulsive force, can reduce its service life; During last upper and lower core rod rigid stamp, board noise is larger, forms noise pollution.
Utility model content
The deficiency that the utility model exists for above-mentioned prior art, provide a kind of simple in structure, easy to operate, the counterdie core rod buffer gear of the basic lids of easy open lids of sheet material good fluidity, it has solved the sheet material poor fluidity that existing mold adopts the buffer structure of rigid stamp to bring, lid is easy to crack, mould is impacted large, the problem such as in the course of work noise is large.
The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of counterdie core rod buffer gear of basic lids of easy open lids, comprise lower bolster, die shoe, lower cutter, lower mold core, compacted under ring and lower retainer ring, it is characterized in that, described die shoe is fixedly connected on described lower bolster, described lower cutter is fixedly connected on the top of described die shoe, described lower retainer ring set is contained in the inner circle of described die shoe and lower cutter, described compacted under ring set is contained in the inner circle of described lower retainer ring, and be fixedly connected with described die shoe, in described compacted under ring, be provided with lower mold core piston, the top of described lower mold core piston is fixedly connected with described lower mold core, in described die shoe and lower bolster, be provided with the die shoe cavity and the lower bolster cavity that are interconnected, described lower bolster cavity is provided with the air flue that is communicated with external air source, described die shoe cavity is connected with the inner chamber lower end of described compacted under ring.
Further, described external air source comprises compressor, overflow valve and air accumulator.
Further, the compressed air air pressure of described lower bolster cavity is 24～26bar.
The beneficial effects of the utility model are: first, change due to mould structure, make in basic cover forming process, the most concentrated capel part of stress first machines, again lid is carried out to drawing and forming, now to reprocess capel sheet material good fluidity after than moulding a lot of for sheet material mobility in mould, material-type varying stress reduces greatly, after having avoided so original processing mode mould because of lid moulding, sheet material poor fluidity, stress such as concentrate at the problem during reshaping capel, have fundamentally overcome the generation of lid cracking, quick-fried lid phenomenon; Secondly, this structure is fixed as an assembly by lower mold core and lower mold core piston, and this assembly can move up and down in compacted under ring inside, can to lower mold core, move up and down control by external air source, by being fixedly connected with of original lower mold core and die shoe, becoming movably and flexibly connect; Again, when upper and lower core rod matched moulds, original rigid stamp is become to flexible punching press, reduce its impact to mould and board, extend its service life; Finally, lower mold core lower end connect lower mold core piston, below increase gas circuit, its matched moulds process is become to soft impulse, reduce noise decibel, reduce noise pollution.In a word, the utility model is simple in structure, easy to operate, and noise is little, has not only guaranteed the quality of product, has extended die life, and has improved operating efficiency.
