Description
Technical field
The present invention relates to a kind of parts of metal casting machine, be specifically related to a kind of for the following core box of core making machine and the retaining mechanism of core box cart stationary.
Background technology
In casting technique, during the preparation core, core box need move back and forth between coremaking station and following plunger tip station, and at the coremaking station, core box is made progress jacking to the lower surface of penetrating sand mechanism, penetrates the sand operation, blows and solidifies; At following plunger tip station, the core after the curing is ejected disengaging from counterdie.The core box dolly is used for realizing that core box reaches shuttling between the plunger tip station down at the coremaking station, is the important component part of core making machine.
Following core box is fixed on the core box dolly, moves with the core box dolly, simultaneously, in the above-mentioned course of work, need carry out matched moulds, die sinking operation repeatedly.Therefore, require core box and the locking of core box travelling car down, both are immobilized by relative position.Location between following core box and core box dolly generally is to cooperate the constraint that realizes all around direction to locate by the alignment pin that is arranged on the core box dolly with the locating hole that following core closes; And the location of upward direction, then mainly adopt the mode of locking bail locking to realize, the structure of locking bail, be similar to disclosed structure among the Chinese patent application CN102078926A, what disclose a kind of cold-box core blower in the document penetrates the plate retaining mechanism, comprise one group of locking bail that is oppositely arranged, the described locking bail that is oppositely arranged has a fixed rotating shaft respectively, described each locking bail that is oppositely arranged is connected with the two ends of same telescopic oil cylinder in hinged mode respectively at the opposite position of its fixed rotating shaft the same side, and described two locking bails that are oppositely arranged relatively rotate along fixed rotating shaft separately simultaneously when shrinking or stretching with the piston rod that forms described telescopic oil cylinder.Similar with the above-mentioned locking mechanism structure of penetrating on the plate, in following core box retaining mechanism, the upper-lower position of oil cylinder and locking bail arranges on the contrary, makes down core box be locked in core box dolly top.
Disclosed locking bail locking mode in the technique scheme, complex structure, space hold is big, the pipeline complexity, for satisfying the revolution of locking bail, must be at core box dolly design revolution fulcrum, driving mechanism must be installed in core box dolly bottom, can satisfy the rotary locking requirement, driving mechanism can not be fixed, and realizes that difficulty is big.
Summary of the invention
Goal of the invention of the present invention provides core box retaining mechanism under a kind of core making machine, with simplified structure, minimizing space hold, is convenient to designing and producing of core box dolly.
To achieve the above object of the invention, the technical solution used in the present invention is: core box retaining mechanism under a kind of core making machine, and described at least one pair of relative side of core box down is ramp; Cooperate with described ramp and to be provided with locking device, described locking device comprises horizontally disposed guide rod, by clamping wedge and the driving mechanism of guide rod guiding, described clamping wedge has a lower inclined plane that cooperates with the ramp of following core box, described driving mechanism drives clamping wedge makes it have the free degree that seesaws along the guide rod direction, under locking state, the described ramp of core box down of the lower inclined plane of described clamping wedge compressing locking.
In the technique scheme, following core box the location of direction all around can by and the core box dolly between locating pin structure or positioning key structure realize; In the direction that makes progress, cooperate between the ramp of the lower inclined plane of locking device and following core box, provide the driving force of horizontal direction by driving mechanism, the component effect by the inclined-plane realizes locking to the ramp of core box down.Described guide rod can directly be fixed on the core box dolly, and the vertical guide at the place, base of guide rod and ramp is arranged vertically, and can guarantee to obtain maximum coupling mechanism force.Guide rod also can adopt line slideway to realize.
Optimized technical scheme in each locking device, is provided with two guide rods that be arranged in parallel.
Further, for ease of processing and fabricating, described two guide rods are arranged in the same horizontal plane.
In the technique scheme, cooperate with the described ramp of core box down, be provided with a pair of described locking device.
A kind of optional scheme in each locking device, is provided with a guide rod, also is provided with the clamping wedge rotation preventing mechanism.Perhaps, described guide rod is line slideway.
In the technique scheme, described driving mechanism is hydraulic cylinder or cylinder.
Optimized technical scheme, the inclination angle of described ramp are 30～60 °.
Because technique scheme is used, the present invention compared with prior art has following advantage:
1. among the present invention, following core box locking device utilizes the rectilinear motion of inclined-plane clamping wedge and driving mechanism, and driving force is converted into a downward coupling mechanism force to following core box, and simple in structure, space hold is little, and pipeline is simple.
2. the present invention does not take core box dolly bottom installing space, is conducive to design and the realization of core box dolly.
3. locking device of the present invention can be fixed on the both sides of core box dolly easily, and is easy for installation, and the guide rod structure of orthoscopic is not fragile, safeguards simple.
