Mold ejection device
Technical Field
The utility model belongs to the technical field of the mould and specifically relates to a mould ejecting device.
Background
The mould is a tool which can make the blank into a finished piece with a specific shape and size under the action of external force, and is widely used for blanking, die forging, cold heading, extrusion, powder metallurgy piece pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like, the mould has a specific outline or inner cavity shape, the blank can be separated according to the contour shape by applying the outline shape with a cutting edge, the blank can obtain a corresponding three-dimensional shape by applying the inner cavity shape, the mould generally comprises a movable mould and a fixed mould which can be separated and combined, the finished piece is taken out when the mould is separated, the blank is injected into a mould cavity for forming when the mould is folded, the mould is a precision tool, has a complex shape, bears the expansion force of the blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of mould production is one of important marks of, the product is taken out in the manual work under the great condition of laminating power between the in-process of punching press and the die, wastes time and energy, and is very inconvenient, has reduced work efficiency.
SUMMERY OF THE UTILITY MODEL
In order to overcome the above-mentioned defect that exists among the prior art, the utility model provides a mould ejecting device.
The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a mold ejection device, includes mould and lower mould, the lower mould corresponds the setting in last mould below, establish the die cavity on the lower mould, the mounting groove is established to the die cavity below, evenly establish the through-hole between mounting groove and die cavity, establish the roof in the through-hole, the roof matches with the through-hole, the ejector pin is established to the roof below, the vertical setting of ejector pin is in the push pedal, the vertical guide arm that sets up in mounting groove both sides, the push pedal slides on the guide arm and sets up, movable electromagnetic plate is established to the push pedal below, the boss is established at the mounting groove middle part, establish fixed electromagnetic plate on the boss.
In the above mold ejection device, four groups of ejector rods are uniformly arranged.
In the above mold ejection device, the movable electromagnetic plate and the fixed electromagnetic plate are connected to the control circuit.
The spring is arranged below the push plate and sleeved on the guide rod, and two ends of the spring are fixedly connected with the push plate and the mounting groove respectively.
The beneficial effects of the utility model are that, the utility model discloses go up the material stamping forming on the mould to the lower mould, the finished product is located the one-tenth die cavity, activity electromagnetic plate is different with fixed electromagnetic plate polarity during the punching press, push pedal and boss laminating, the spring pressurized, after the punching press is accomplished, control activity electromagnetic plate magnetism conversion, activity electromagnetic plate produces the repulsion force with fixed electromagnetic plate polarity is the same, under the auxiliary action of spring, the push pedal rises, drive ejector pin and roof upward movement, it is ejecting in by the one-tenth die cavity with the finished product, ejecting back activity electromagnetic plate converts magnetism once more, moreover, the steam generator is simple in structure, ejecting off-the-shelf convenience, and the work efficiency is improved.

In the figure, 1, an upper die, 2, a lower die, 3, a forming cavity, 4, a mounting groove, 5, a through hole, 6, a top plate, 7, an ejector rod, 8, a push plate, 9, a guide rod, 10, a movable electromagnetic plate, 11, a boss, 12, a fixed electromagnetic plate and 13, a spring are arranged.
Detailed Description
In order to more clearly illustrate the technical solution of the present invention, the following provides a further description of the present invention with reference to the accompanying drawings, and obviously, the following described drawings are only one embodiment of the present invention, and for those skilled in the art, other embodiments can be obtained according to the drawings and the embodiment without any creative work, and all belong to the protection scope of the present invention.
The utility model provides a mold ejection device, includes mould 1 and lower mould 2, its characterized in that: lower mould 2 corresponds the setting in last mould 1 below, establish into die cavity 3 on lower mould 2, installation groove 4 is established to die cavity 3 below, evenly establish through-hole 5 between installation groove 4 and die cavity 3, establish roof 6 in the through-hole 5, roof 6 matches with through-hole 5, ejector pin 7 is established to roof 6 below, the vertical setting of ejector pin 7 is on push pedal 8, the vertical guide arm 9 that sets up in installation groove 4 both sides, push pedal 8 sets up in the sliding on guide arm 9, activity electromagnetic plate 10 is established to push pedal 8 below, boss 11 is established at 4 middle parts of installation groove, establish fixed electromagnetic plate 12 on the boss 11.
In detail, the ejector pin 7 evenly sets up four groups, activity electromagnetic plate 10 and fixed electromagnetic plate 12 access control circuit, spring 13 is established to push pedal 8 below, spring 13 cover is established on guide arm 9, spring 13 both ends respectively with push pedal 8 and mounting groove 4 fixed connection.
During the use, go up the material stamping forming on mould 1 pair lower mould 2, the finished product is located shaping chamber 3, during the punching press activity electromagnetic plate 10 is different with fixed electromagnetic plate 12 polarity, push pedal 8 and the laminating of boss 11, spring 13 is pressed, after the punching press is accomplished, control activity electromagnetic plate 10 magnetic conversion, activity electromagnetic plate 10 produces the repulsion force with fixed electromagnetic plate 12 polarity is the same, under spring 13's auxiliary action, push pedal 8 rises, drive ejector pin 7 and roof 6 upward movement, it is ejecting to be ejecting in the finished product by shaping chamber 3, ejecting back activity electromagnetic plate 10 converts magnetism once more, moreover, the steam generator is simple in structure, ejecting finished product is convenient, and work efficiency is improved.
The above embodiments are only exemplary embodiments of the present invention, and are not intended to limit the present invention, and the protection scope of the present invention is defined by the claims.
