Detailed ways

As shown in the figure, the structural scheme and working process of the utility model are further described in conjunction with examples. As shown in Figure 1, a plastic mold that uses elastic elements to limit the opening includes a movable mold seat plate 1, a pad 2, a limit screw 3, a support plate 4, a core fixing plate 5, a cavity plate 6, polyurethane Set 7, push piece plate 8, fixed mold seat plate 9, small limit screw 10, guide post 11, guide sleeve 12, positioning ring 13, sprue sleeve 14, runner rod 15, upper core 16, core 17 , large guide post 18, pusher plate guide sleeve 19, large guide sleeve 20, retaining ring 21, lower push plate 22, push rod 23, fixed plate 24, lower guide sleeve 25 and lower guide post 26. The movable mold seat plate 1 is fixed on the core fixing plate 5 with bolts through the cushion block 2 and the supporting plate 4, and the four guide posts 11 and the core 17 are fixed on the supporting plate 4 through the core fixing plate 5, and the four guide posts 11 is set on the cavity plate 6 through the guide sleeve 12, the four guide columns 11 can slide in the guide sleeve 12, the upper core 16 is fixed on the cavity plate 6 by screws, and the four polyurethane sleeves 7 are fixed on the support by screws On the plate 5, four small limit screws 10 are set on the fixed mold seat plate 9, and fixed on the push piece plate 8, the runner rod 15 and the sprue sleeve 14 are fixed on the fixed mold seat plate 9 through the positioning ring 13 , 4 large guide posts 16 are fixed on the fixed mold seat plate 9, and are arranged on the pusher plate 8 and the cavity plate 6 through the pusher plate guide sleeve 19 and the large guide sleeve 20, and the 4 large guide posts 16 can be The pusher plate guide sleeve 19 and the large guide sleeve 20 slide, and the four retaining rings 21 are respectively fixed on the large guide post 16 by screws, and the four push rods 23 are fixed on the lower push plate 22 with the fixed plate 24, and the fixed plate 24 and The lower push plate 22 is set in the cushion block 2, and the two lower guide columns 26 are fixed on the movable mold seat plate 1, and the two lower guide columns 26 are set on the lower push plate 22 and the fixed plate 24 through the lower guide sleeve 25, and two The lower guide post 26 can slide in the lower guide sleeve 25 .

The working process of the present utility model is: when the movable mold seat plate moves and begins to type, the cavity plate 6 is tightened due to the friction force of the polyurethane sleeve 7, and the I-I surface starts to type, and the pouring system aggregate is broken at the gate; When the small limit screw 3 works, the cavity plate 6 stops moving. At this time, II-II begins to form, and the sprue condensate comes out of the sprue sleeve 14. At this time, the small limit screw 10 and the large guide post 18 start Effect, III-III starts parting, and the plastic parts are ejected from the core 17 by the push rod 23 .
