Abstract
The invention relates to an adjustable ejecting device, and belongs to the technical field of casting. The technical scheme adopted by the adjustable ejecting device disclosed by the invention is that a connecting rod is provided with an adjustor, and the adjustment of an initial position of an ejector rod is realized through adjusting an initial position of the connecting rod; the connecting rod and the ejector rod are in transmission by adopting a chute sliding block, and the adjusting accuracy can be increased through the conversion of displacement of a chute; guiding posts are arranged in the ejecting direction, and the stability of adjusting the position of the ejector rod can be ensured; finally, the casting and printing height of the ejector rod on a casting piece can be effectively controlled by accurately adjusting the position of the ejector rod.
Description
Technical field
Type of the present invention relates to a kind of foundry goods liftout attachment, belongs to casting technology field.
Background technology
Casting mould often adopts push rod ejection device.As shown in Figure 1, the ideal position of push rod is that end face is concordant with profile, if the too high or too low push rod that forms differing heights on foundry goods that all can make in push rod position is cast, push rod casts highly to exceed standard can affect normal process and the use of foundry goods.The push rod length reduction that the push rod position deviation manufacture, rigging error causing and wearing and tearing, corrosion cause all can cause this defect.
In existing technology, for addressing the above problem, common employing examination is joined, modification method obtains suitable push rod position, and often changes the push rod that weares and teares and avoid defect generation.There is certain die assembly difficulty in existing method, often changes push rod and can reduce production efficiency, consumable material.
inventing type content
The object of type of the present invention is, a kind of adjustable liftout attachment is provided, and casts height in order to control push rod.The technical scheme of type of the present invention is: first, adjuster is set on connecting rod, by regulating the original position of connecting rod to realize the adjustment of push rod original position.Secondly, between push rod and connecting rod, adopt the transmission of skewed slot slide block.According to skewed slot top offset vector correlation, in the time that skewed slot and bottom surface angle are θ, push rod and connecting rod displacement ratio k=tan θ.Adopt the skewed slot angle of k<1 to promote the adjustment precision of push rod position.Again, according to the push rod direction of motion, lead is installed, is guaranteed the stability that push rod position is adjusted.Finally, by the accurate adjustment of push rod original position having been realized to effective control of push rod being cast to height.
Compared with prior art, it is advantageous that: when die assembly, push rod position directly adjustable, need not revise, reduced die assembly difficulty.In production process, when push rod wear extent is excessive, by increasing adjuster compensation rate, make push rod recover ideal position.So not only control in time the height that push rod is cast, and avoided shutdown, replacing, improved production efficiency, saved material.
Accompanying drawing explanation
Accompanying drawing 1 is push rod ideal position schematic diagram.
Accompanying drawing 2 is type structural representation of the present invention.
The specific embodiment
This device is made up of push rod 2, hydraulic cylinder 3, connecting rod 4, adjuster 7, pallet 8, skewed slot slide block 9, lead 10, base plate 11 as shown in Figure 2.
Caging bolt 5 is housed on adjuster 7, side plate 6 is housed on connecting rod 4, caging bolt 5 ejection side plates 6, to adjust the original position of connecting rod 4.Bearing fit transition shift amount on the skewed slot of skewed slot slide block 9 and pallet 8.Skewed slot and bottom surface angle are 30o, can realize the accurate adjustment of push rod position.Lead 10 is installed in pallet 8 both sides, keeps displacement stable.Push rod 2 is arranged on pallet 8.Adjuster 7, lead 10 are arranged on base plate 11.Connecting rod 4 is connected with hydraulic cylinder 3, skewed slot slide block 9 respectively.
Push rod 2 is in the time of return state, and turn caging bolt 5 makes connecting rod 4 horizontal displacements, and drives skewed slot slide block 9 synchronous shift.Conversion by skewed slot to displacement, pallet 8 carries out micro-vertical displacement, and push rod 2 is realized fine position under the drive of pallet 8.As shown in Figure 1, when push rod reaches ideal position, push rod is cast highly and is effectively controlled.
