Abstract
The utility model discloses a lever-boosted pushing plate applicable to a die-casting mould. The lever-boosted pushing plate applicable to the die-casting mould comprises a movable mould seat plate, wherein the movable mould seat plate is connected with a supporting plate through a mould leg; the supporting plate is connected with a fixed mould bushing plate; a mould core is arranged in the middle of the fixed mould bushing plate; a mould cavity is formed between the fixed mould bushing plate and the mould core; and a sprue bushing is arranged at the front end of the mould core. The lever-boosted pushing plate applicable to the die-casting mould is characterized in that pushing plates are arranged on the two sides of the mould core; the pushing plates are inlaid into the supporting plate; a push rod I is arranged on the pushing plate on one side; a push rod II is arranged on the mould core; the push rod I and the push rod II penetrate through the supporting plate and are connected with push rod fixing plates; the push rod fixing plates are connected with the pushing plates; a pair of lever bases are arranged at the two ends of the pushing plates; each lever base is connected with a lever through a shaft; one end of each lever is supported on the movable mould seat plate through a column; and the other ends of the levers are supported by the push rods of a machine tool. The lever-boosted pushing plate applicable to the die-casting mould has the advantage that an initial pushing force can be added to overcome an initial core-pulling resistance of the mould core, so that a cast can be protected from deformation due to a too large stress in a pushing process.
Description
Technical field
The utility model relates to a kind of lever augmented push piece plate that is applied in the die casting.
Background technology
Foundry goods is generally dark tubular, interior hole depth, diameter is large, core can be very large to the resistance of initially loosing core of foundry goods, therefore to from core, take out foundry goods, need larger ejecting force, but in the push piece process, the thrust of depending merely on die casting machine self is difficult to foundry goods is pushed away core, sometimes can cause because of the excessive of ejecting force the distortion of foundry goods.
Therefore, be badly in need of a kind of improved technology and solve existing this problem in the prior art.
Summary of the invention
The purpose of this utility model provides a kind of lever augmented push piece plate that is applied in the die casting.
The technical solution adopted in the utility model is:
A kind of lever augmented push piece plate that is applied in the die casting, comprise Bottom clamp plate, described Bottom clamp plate is connected with gripper shoe by the mould pin, described gripper shoe is connected with the cover half cage plate, be provided with core in the middle of the described cover half cage plate, be provided with mold cavity between described cover half cage plate and the core, described core front end is provided with sprue bush, described core both sides are provided with the push piece plate, described push piece plate is embedded in the gripper shoe, and the push piece plate of a described side is provided with the push rod I, and described core is provided with the push rod II, described push rod I is connected with the push rod II and is passed gripper shoe and be connected with ejector pin retaining plate, described ejector pin retaining plate is connected with push pedal, and described push pedal two ends are provided with a pair of lever seat, and described each lever seat is connected with lever by axle, one end of described lever is supported on the Bottom clamp plate by cylinder, and the other end of described lever is supported on the lathe push rod.
Described lever, cylinder, axle, push pedal and push pedal fixed head all are located in the cavity of mould pin formation.
The utility model has the advantages that: adopt lever augmented ejecting mechanism, can increase initial ejecting force, overcome the resistance of initially loosing core of core; Adopt the push piece plate, the lifting surface area of foundry goods when having increased push piece has reduced the unit pushing force of foundry goods, has avoided foundry goods in push because stressed excessive and be out of shape.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cutaway view of the AA direction of Fig. 1 in the utility model.
Wherein: 1, lever, 2, cylinder, 3, axle, 4, lever seat, 5, push pedal, 6, ejector pin retaining plate, 7, push rod I, 8, the push piece plate, 9, core, 10, sprue bush, 11, Bottom clamp plate, 12, the mould pin, 13, push rod II, 14, gripper shoe, 15, the cover half cage plate, 16, lathe push rod, 17, mold cavity.
The specific embodiment
As depicted in figs. 1 and 2, a kind of lever augmented push piece plate that is applied in the die casting of the present utility model, comprise Bottom clamp plate 11, Bottom clamp plate 11 is connected with gripper shoe 14 by mould pin 12, gripper shoe 14 is connected with cover half cage plate 15, be provided with core 9 in the middle of the cover half cage plate 15, be provided with mold cavity 17 between cover half cage plate 15 and the core 9, core 9 front ends are provided with sprue bush 10, core 9 both sides are provided with push piece plate 8, push piece plate 8 is embedded in the gripper shoe 14, the push piece plate 8 of one side is provided with push rod I 7, core 9 is provided with push rod II 13, and push rod I 7 is connected with the push rod II and is all passed gripper shoe 14 and be connected with ejector pin retaining plate 6, and ejector pin retaining plate 6 is connected with push pedal 5, push pedal 5 two ends are provided with a pair of lever seat 4, each lever seat 4 is connected with lever 1 by axle 3, and an end of lever 1 is supported on the Bottom clamp plate 11 by cylinder 2, and the other end of lever 1 is supported on the lathe push rod 16.
Lever 1, cylinder 2, axle 3, push pedal 5 and push pedal fixed head 6 all are located in the cavity of mould pin 12 formation.
During push piece, lathe push rod 16 promotes lever 1 and moves forward, the lever 1 of lever seat 4 upper ends rotates counterclockwise around axle 3, the lever 1 of lever seat 4 lower ends is done around axle 3 and is clockwise rotated, simultaneously take cylinder 2 as fulcrum, by axle 3 and lever seat 4, promote push pedal 5, push pedal 5 promotes push pedal fixed head 6, push pedal fixed head 6 promotes forward push rod I 7 and push rod II 13, under the acting in conjunction of push rod I 7 and push rod II 13, promote 8 reaches of push piece plate, the resistance of initially loosing core that overcomes core 9 is namely eliminated foundry goods to the quiet package power of core 9, (a+b)/b that this moment, ejecting force was about lathe push rod 16 thrusts doubly, the b/ (a+b) that push piece plate 8 speed of advancement are about lathe push rod 16 speed of advancement is doubly.When lever 1 when axle 3 goes to its long and straight section and push pedal 5 and fits, the reinforcement recommendation process finishes, and foundry goods is eliminated the quiet package power of core 9, along with lathe push rod 16 continues reach, push piece plate 8 has the thrust and the migration velocity that communicate that foundry goods is pushed away core 9 with lathe push rod 16, therefrom takes out foundry goods.
