Detailed Description
The technical solution of the present invention is further explained with reference to the drawings and the embodiments.
Example one
As shown in fig. 1 and fig. 2, an embodiment of the present invention provides an ejection mechanism for an injection molding part, which includes a housing 1, a top plate 2 and a control component for driving the top plate 2 to move are disposed in the housing 1, specifically, the control component includes an electromagnet 3 fixed at the top of the housing 1, the top plate 2 is made of a metal with magnetism, the top process of the top plate 2 is simplified by the disposed electromagnet 3 and the top plate 2 made of a metal with magnetism, automatic ejection and resetting can be realized by controlling the power on/off of the electromagnet 3, the top of the top plate 2 is further fixedly connected with two springs 4, the two springs 4 are symmetrically distributed on the top plate 2, one end of the spring 4 is fixedly connected with the top plate 2, the other end of the spring 4 is fixedly connected with the top of the housing 1, and by the disposed spring 4, make electro-magnet 3 when adsorbing and holding a board 2, can increase electro-magnet 3 through compression spring 4 and relieve the kinetic energy of adsorbing, when a board 2 whereabouts, spring 4 can play a connection spacing effect simultaneously. The periphery side of the spring 4 is provided with a circle of insulating isolation belt 11, the isolation belt 11 is fixedly connected with the shell 1, and the electromagnet 3 is prevented from influencing the spring 4 when in power-on work through the arranged isolation belt 11. Mounting hole 6 has been seted up at 1 top of casing, and is concrete, the quantity of mounting hole 6 is two, and symmetric distribution is in 1 top of casing, but 6 endotheca of mounting hole have connect vertically movable helping hand pole 8, the both ends of helping hand pole 8 are all fixedly connected with rubber pad 9 (not shown in the figure), through the rubber pad 9 that helping hand pole 8 both ends set up, make the user when supplementary drive kicking piece board 2 downstream through knocking helping hand pole 8, reduce the harm to 8 end contact departments of helping hand pole. Still fixedly connected with is used for spacing collar 5 of helping hand pole 8 in the casing 1, 6 coaxial settings of mounting hole on collar 5 and the casing 1, through the collar 5 that sets up, make helping hand pole 8 can obtain spacing of collar 5 in casing 1, and then be convenient for carry out vertical removal. The bottom of the shell 1 is provided with a piece outlet hole 7 for the top piece plate 2 to pass through, the bottom of the top piece plate 2 is also fixedly connected with a rubber pad 9, and the rubber pad 9 arranged at the bottom of the top piece plate 2 enables the top piece plate 2 to play a certain protection role on the injection molding workpiece 14 when the injection molding workpiece 14 is ejected. 1 top of casing is provided with and is used for knocking power assisted rod 8 and carries out the power spare of vertical removal, and is concrete, power spare is cylinder 10, the top fixedly connected with fixed plate 12 of casing 1, cylinder 10 fixed connection is on fixed plate 12, and through the power spare that is used for knocking power assisted rod 8 and carries out vertical removal that sets up, messenger's user can pass through control power spare, can realize knocking power assisted rod 8 to supplementary drive ejecting work piece 14 of moulding plastics of ejecting 2 downstream of ejecting board, reduce the harm to 14 surperficial of the work piece of moulding plastics.
When the injection molding device is used, an injection mold 13 provided with an injection molding workpiece 14 is manually placed below the shell 1 to be fixed, so that the ejector plate 2 is aligned with the injection molding workpiece 14 to be ejected, then the electromagnet 3 is powered off, the compressed spring 4 releases compression to drive the ejector plate 2 to eject, and the injection molding workpiece 14 is ejected; when the work piece 14 of moulding plastics was too inseparable with injection mold 13's bonding, the work piece 14 of moulding plastics was failed to ejection plate 2 normally ejecting, artifical inserting helping hand pole 8 and passing spacing ring 5 in mounting hole 6 this moment, helping hand pole 8 is vertical to be inserted in casing 1 and to be inconsistent with ejection plate 2, then two helping hand poles 8 about strikeing in proper order through two cylinders 10 of control start helping hand pole 8 top are in order to assist and drive ejection plate 2 ejection, perhaps the manpower is strikeed in proper order about strikeing in proper order and is carried out the ejection with the assistance of driving ejection plate 2, the work piece 14 of moulding plastics is ejecting after, restart electro-magnet 3 adsorbs ejection plate 2 and compression spring 4, can artifical support ejection plate 2 and remove to electro-magnet 3 when ejection plate 2 is far away with electro-magnet 3, so that electro-magnet 3 adsorbs.
Example two
As shown in fig. 3 and 4, the difference between the first embodiment and the second embodiment is only that the control component drives the top plate 2 to move, the control component in the first embodiment is an electric telescopic rod 15 fixedly connected to the top inside the housing 1, and the output end of the electric telescopic rod 15 is fixedly connected to the top of the top plate 2.
When the ejection device is used, an injection mold 13 provided with an injection workpiece 14 is manually placed below the shell 1 to be fixed, so that the ejection plate 2 is aligned with the injection workpiece 14 to be ejected, and then the electric telescopic rod 15 is controlled to drive the ejection plate 2 to move downwards to eject the injection workpiece 14; when the work piece 14 of moulding plastics is too inseparable with injection mold 13's bonding, the work piece 14 of will moulding plastics is failed to roof board 2 normally ejecting, artifical this moment insert helping hand pole 8 in mounting hole 6 and pass spacing ring 5, helping hand pole 8 is vertical to be inserted in casing 1 and to be inconsistent with roof board 2, then strike in proper order through the manpower about two helping hand poles 8 carry out the roof with supplementary drive roof board 2, or two cylinders 10 of control start helping hand pole 8 top strike in proper order about two helping hand poles 8 with supplementary drive roof board 2 roof, at the in-process that strikes helping hand pole 8, electric telescopic handle 15 still drives roof board 2 and moves down the roof, helping hand pole 8 plays supplementary helping hand effect, after the work piece 14 of moulding plastics is ejecting, manual control electric telescopic handle 15 withdraws roof board 2 to initial condition.
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
