Description of the embodiments
The utility model will be further described with reference to the accompanying drawings.
Examples
The utility model provides a drag hook structure for controlling die sinking order, see fig. 4 and 5, includes first drag hook 1, first drag hook 1 left and right sides symmetry is provided with second drag hook 2 and third drag hook 8, still includes first movable block 9 and second movable block 10 to and fixed plate 3, fixed apron 5, spring 6 and headless screw 7, second drag hook 2 and first movable block 9 linkage, third drag hook 8 and second movable block 10 linkage.
The injection mold consists of the drag hook structure and comprises a front mold fixing plate a, a thin water gap plate h and an A plate c which are sequentially arranged from top to bottom; the device comprises a push plate d, a B plate e, square iron f, a rear mould fixing plate g and a drag hook structure i, wherein the drag hook structure i comprises a first drag hook 1, a second drag hook 2 and a third drag hook 8 are symmetrically arranged on the left side and the right side of the first drag hook 1, the drag hook further comprises a first movable block 9, a second movable block 10, a fixing plate 3, a fixing cover plate 5, a spring 6 and a headless screw 7, the first drag hook 1 is fixed on the side face of the A plate c, the second drag hook 2 and the third drag hook 8 are fixed on the side face of the B plate e, the fixing plate 3 and the fixing cover plate 5 are fixed on the side face of the push plate d, and the first movable block 9, the second movable block 10, the spring 6 and the headless screw 7 are arranged in grooves and holes between the fixing plate 3 and the fixing cover plate 5;
working principle: the first draw hook 1 is clamped on the first movable block 9 after moving for a certain distance (the distance is set according to actual needs) by utilizing the mold opening action of the injection molding machine, meanwhile, the third draw hook 8 pulls the second movable block 10 to enable the push plate d not to move along with the A plate c, along with the progress of the mold opening action, after the inclined plane of the first draw hook 1 contacts with the second movable block 10, the second movable block 10 starts to transversely move until the inclined plane is separated, after that, the first draw hook 1 drives the push plate d to move, and after the inclined plane of the second draw hook 2 contacts with the first movable block 9, the first movable block 9 starts to transversely move until the inclined plane is separated, the first draw hook 1 is separated from the first movable block 9, and the push plate d stops moving.
