Abstract
The utility model discloses a die assembly of the back rest head rest of the car seat. The utility model comprises an upper mold plate connected with a female die and a lower mold plate connected with a male die, the raised shape f the male die adopts a head rest plate shape, the shape of the female die is complemented and matched with the shape of the male die, a clamping ring is arranged on the lower mold plate, a hydraulic push rod is arranged at the lower part of the clamping ring, a plurality of workpiece positioning pins are arranged on the clamping ring and a positioning hole is arranged at the corresponding position of the female die. An elastic element is arranged between the clamping ring and the lower mold plate, the clamping ring is tightly connected with the lower mold plate through a bolt, and the shape of the inner ring of the clamping ring is consistent with the shape of the raised outer ring of the male die. Because the die assembly adopts the technology proposal, the shape f the die assembly is combined with the clamping ring and the positioning pin, to ensure that the pre-formed part of the back rest head rest of the car seat can be processed and formed smoothly in the die assembly, and the problems that the part is torn and gigged and the die assembly is damaged are avoided.
Description
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of motor vehicle seat back headrest-plate mould.
Background technology
The motor vehicle seat back headrest-plate is the vital part of pegging graft and resting the head on the car seat back frame; in the past because domestic not this part; external buying that can only be a large amount of, not only cost is expensive but also supplied by the assembly that usually can influence the backrest skeleton that pins down of international vendor.The motor vehicle seat back headrest-plate is a safety member, have relatively high expectations, its general shape is a pincushion, plane of the right and left projection, two interplanars connect a transition of depression slightly, in the middle of the concave transition is a headrest portion of caving in, extend a plane of more caving in order to be connected in the concave transition lower edge with motor vehicle seat back, this headrest-plate is complex-shaped, by the inside multistage transition depression in plane, and overall depression is darker, the maximum distortion zone of material when innermost two corners of caving in are part processing, be very easy to produce material and be thinned to the state of tearing, caused certain difficulty for this part of processing.What external this part of production adopted is high-intensity stamping material, but using homemade substitution material to add man-hour, because the plasticity and the percentage elongation of material are relatively poor, during drawing and forming since material mobile unbalanced be very easy to tear and make phenomenons such as mould is hot, hardness reduction, part plucking in the maximum recess generation of part, so in the processing of this part, drawing is the emphasis operation of this forming parts.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of motor vehicle seat back headrest-plate mould of smooth drawing and moulding.
For solving the problems of the technologies described above; the utility model motor vehicle seat back headrest-plate mould comprises cope match-plate pattern and lower bolster; also comprise die and punch; described die is connected with described cope match-plate pattern; described punch is connected with described lower bolster; the convex shape of described punch is the headrest-plate shape; the complementary coupling of the shape of described die and described punch; on described lower bolster, be provided with blank holder; described blank holder has hydraulic mandril; on described blank holder, be provided with some workpiece alignment pins, on described die, be provided with and the corresponding locating hole of described workpiece alignment pin.Described cope match-plate pattern is connected by bolt with described die, and described lower bolster is connected by bolt with described punch.Described workpiece alignment pin head end is provided with screw rod, and the relevant position of the fixing described workpiece alignment pin of described blank holder is provided with screw, and described workpiece alignment pin is fixed on the described blank holder by the screw rod screw.Be provided with flexible member between described blank holder and described lower bolster, described blank holder hangs tight by bolt with described lower bolster and is connected, and loop-shaped is consistent with the outer loop-shaped of punch projection in the described blank holder.
Because the utility model motor vehicle seat back headrest-plate mould adopts technique scheme, be that mold shape combines with blank holder and alignment pin, make the machine-shaping smoothly in this mould of preformed motor vehicle seat back headrest part, avoided that part is torn, the problem of plucking, mould damage.
