The specific embodiment
Embodiment describes in further detail the present invention below in conjunction with accompanying drawing.
As shown in the figure, a kind of full electric injection molding machine hangs down the inertia ejecting mechanism, comprises barrel assembly 1, hopper seat 2, preformed seat 3, injection moulding seat 4, preformed drive unit, penetrates drive unit; Hopper seat 2 is fixedly connected on the preformed seat 3, is fixedly connected through connecting rod 5 between preformed seat 3 and the injection moulding seat 4, and the preformed drive unit comprises preformed motor 6, preformed driving wheel 61, preformed driven pulley 62 and preformed driving-belt 63; Penetrating drive unit comprises ejaculation motor 7, penetrates driving wheel 71, penetrates driven pulley 72 and penetrates driving-belt 73; Preformed motor 6 is fixedly mounted on respectively on the injection moulding seat 4 with ejaculation motor 7, is connected with screw mandrel 8 in the injection moulding seat 4, screw mandrel 8 and ejaculation driven pulley 72 coaxial fixed connections; Be connected with the thrust bearing 9 coaxial in the preformed seat 3 with screw mandrel 8; Screw rod 11 coaxial fixed connections in the front end of thrust bearing 9 and the barrel assembly 1, the coaxial shaft coupling 91 that is arranged with in the rear portion of thrust bearing 9 is fixedly connected with slip flat key 92 on the thrust bearing 9; The inner surface of shaft coupling 91 is provided with the keyway that matches with slip flat key 92 that axially runs through; Preformed driven pulley 62 is coaxial fixedly sleeved on shaft coupling 91, is bolted with transmission nut 81 on the screw mandrel 8, and transmission nut 81 is fixedly connected with the rear end of thrust bearing 9; Be provided with the endoporus 93 that matches with screw mandrel 8 in the rear end of thrust bearing 9; The front end of the rear end of preformed seat 3 and injection moulding seat 4 cooperates through rotary oil seal 31 sealed rotational respectively with between the preformed driven pulley 62, and screw mandrel 8 is connected in the injection moulding seat 4 through bearing shaft, and bearing is provided with bearing block 41; Bearing block 41 is fixedly connected with injection moulding seat 4; The outer end of bearing block 41 is fixedly connected with bearing (ball) cover 42, is provided with oil sealing 43 between injection moulding seat 4 and the bearing block 41, is provided with rotary oil seal 31 between bearing (ball) cover 42 and the screw mandrel 8.
