Detailed description of the invention
Below by embodiment also by reference to the accompanying drawings, the invention will be further described:
As shown in Figure 1, a kind of car seat headrest vertical-foaming mould, primarily of compositions such as large cylinder 1, little cylinder 2, air cylinder support 3, patrix mold insert 4, loose plug 5, patrix 6, counterdie 7, magnet 8, large cylinder limited block 10, large cylinder leads 11.
Patrix 6 and counterdie 7 snap together and form the die cavity A that foams that rests the head on, and patrix 6 is setting up and down with counterdie 7, forms vertical headrest foaming mould.
Large cylinder 1, little cylinder 2 are vertical cylinder, and large cylinder 1 is arranged on the top of air cylinder support 3, and little cylinder 2 is arranged on the top of patrix mold insert 4.The left and right two ends of air cylinder support 3 are extended left and right sidewall that is rear and patrix 6 vertically downward and are fixed together by fastening bolt, and on the left and right sidewall of patrix 6, on the plate body that the left and right two ends of air cylinder support 3 extend vertically downward, correspondence is provided with bolt through-hole.The piston-rod lower end of large cylinder 1 is connected with patrix mold insert 4, drives patrix mold insert 4 to move up and down by large cylinder 1.
Composition graphs 1---shown in Fig. 5, the circular hole 4a being provided with up/down perforation in patrix mold insert 4 supplies the piston rod of little cylinder 2 to pass through, and the bottom of patrix mold insert 4 is provided with groove 4b, the contour shape of groove 4b and the top outline of loose plug 5.The top of loose plug 5 is stretched in the groove 4b bottom patrix mold insert 4, and the top of the top of loose plug 5 and groove 4b is fixed together by the magnetic force of magnet 8, namely at the top of loose plug 5, the top of groove 4b is respectively arranged with the magnet 8 that quantity is equal, position is corresponding, the magnetic force of magnet 8 should ensure that patrix mold insert 4 can drive loose plug 5 to move up and down together under not being subject to External Force Acting.Patrix 6 top is provided with the top cavity B with patrix mold insert 4 outline, and patrix mold insert 4 drives loose plug 5 to move from top to bottom together, and patrix mold insert 4 stretches in the top cavity B of patrix 6, and loose plug 5 reaches in headrest foaming die cavity A.
Preferably, totally two, little cylinder 2, is symmetricly set on the left and right sides of large cylinder 1 piston rod, to facilitate layout, and ensures left and right stress balance; Large cylinder limited block 10 is provided with between the piston rod of each little cylinder 2 and large cylinder 1; the lower end of large cylinder limited block 10 is fixed on patrix mold insert 4 top; and large cylinder limited block 10 is higher than little cylinder 2; stroke limit during for moving upward to large cylinder 1; prevent little cylinder 2 from clashing into air cylinder support 3, thus protect little cylinder 2.
In addition, be also provided with two large cylinder leads 11 be symmetrically arranged between air cylinder support 3 and patrix mold insert 4, ensure the stationarity that large cylinder 1 moves.
During operation, first in the die cavity of counterdie 7, add raw material, drive patrix to turn over by other switching mechanism to turn 90 degrees, drive patrix mold insert 4 by large cylinder 1 again, loose plug 5 moves downward (patrix mold insert 4 with loose plug 5 be fixed together by the magnetic force of magnet 8) together, patrix mold insert 4 is stretched in the top cavity B of patrix 6, and loose plug 5 reach in headrest foaming die cavity A and realize matched moulds; Afterwards, the workpiece 9 in headrest foaming die cavity A and loose plug 5 one-body molded (as shown in Figure 4, Figure 5); Before die sinking, first patrix mold insert 4 is driven to move upward to qualifying bit by large cylinder 1, again by little cylinder 2 piston rod through patrix mold insert 4 circular hole 4a and reach the below of patrix mold insert 4, the thrust of little cylinder 2 is greater than the magnetic force of magnet 8 thus is pushed open by loose plug 5, finally turned over to turn 90 degrees by switching mechanism drive patrix and open patrix 6, take out integrated workpiece 9 and loose plug 5.
