Description
Technical field
the utility model relates to Mold Core-pulling Mechanism technical field, particularly a kind of mould centering type core-pulling mechanism.
Background technology
at present, traditional Mold Core-pulling Mechanism, under certain conditions due to the restriction of Existential Space structure, drive slide block to move the oil cylinder of loosing core and need eccentric setting, namely slipper block loose core moving direction and cylinder force direction are not on the same line, and when the eccentric distance that oil cylinder is arranged is larger, oil cylinder is when driving slipper block loose core, have moment, when slide block starts mobile, easily occur stuck phenomenon.
Utility model content
Technical problem to be solved in the utility model is to provide that a kind of structure is simple, the mould centering type core-pulling mechanism of reliable operation,
For solving the problems of the technologies described above adopted technical scheme: a kind of mould centering type core-pulling mechanism, comprise the cover half cage plate being fitted to each other and connecting, dynamic model cage plate, fixed die insert, moving die insert, to loose core mold insert and core-pulling slide block, described core-pulling slide block moves to drive mold insert of loosing core to carry out loosing core action, two driving oil cylinders are provided with in described cover half cage plate side, the moving direction and two of described core-pulling slide block drives the moving direction of the piston rod of oil cylinder to parallel, the piston rod end of oil cylinder is driven to be connected with a draw back plate described in two, described core-pulling slide block is connected with a slide block backboard, described draw back plate is fixedly connected with slide block backboard by many pull bars, wedge structure is provided with between described core-pulling slide block and dynamic model cage plate, when described dynamic model cage plate moves, described core-pulling slide block is mobile slight distance under wedge structure effect.
Further, for being flexibly connected, there is free gap between described core-pulling slide block and slide block backboard in described core-pulling slide block and slide block backboard, and the size of described slight distance is less than the size of free gap
Further, described core-pulling slide block is provided with the first wedge, described dynamic model cage plate is provided with the second wedge be connected with the first wedge inclined-plane.
Further, described cover half cage plate and two drives between oil cylinder and is provided with thermal insulation board.
Beneficial effect: this mould centering type core-pulling mechanism by arranging wedge structure between core-pulling slide block and dynamic model cage plate, during mould die sinking, first by the ramp effect of wedge structure, prize core-pulling slide block and move one section of slight distance, then just by driving oil cylinder to pull core-pulling slide block to move remaining stroke, avoid just starting drag core-pulling slide block and carry out occurring when loosing core action the phenomenon that core-pulling slide block is stuck, improve core-pulling slide block traveling comfort.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further;
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
With reference to Fig. 1, a kind of mould centering type of the utility model core-pulling mechanism, comprise the cover half cage plate 1 being fitted to each other and connecting, dynamic model cage plate 2, fixed die insert 3, moving die insert 4, to loose core mold insert and core-pulling slide block 5, core-pulling slide block 5 moves to drive mold insert of loosing core to carry out loosing core action, two driving oil cylinders 6 are provided with in cover half cage plate 1 side, the moving direction and two of core-pulling slide block 5 drives the moving direction of the piston rod of oil cylinder 6 to parallel, two drive the piston rod end of oil cylinder 6 to be connected with a draw back plate 7, core-pulling slide block 5 is connected with a slide block backboard 8, draw back plate 7 is fixedly connected with slide block backboard 8 by many pull bars 9, wedge structure is provided with between core-pulling slide block 5 and dynamic model cage plate 2, when dynamic model cage plate 2 moves, core-pulling slide block 5 is mobile slight distance under wedge structure effect.
In the present embodiment, two drive oil cylinder 6 interval to be fixedly installed on cover half cage plate 1 side, core-pulling slide block 5 is between cover half cage plate 1 and dynamic model cage plate 2, when carrying out die sinking, two drive oil cylinder 6 work to drive core-pulling slide block 5 level to move right carries out loosing core action, owing to driving oil cylinder 6 and core-pulling slide block 5 not on the same line, drive oil cylinder 6 by draw back plate 7, slide block backboard 8 and pull bar 9 have just started drag core-pulling slide block 5 when moving, due to moment effect, often core-pulling slide block 5 there will be stuck phenomenon, in order to avoid stuck, by arranging wedge structure between core-pulling slide block 5 and dynamic model cage plate 2, during mould die sinking, first by the ramp effect of wedge structure, prize core-pulling slide block 5 and move one section of slight distance, then just by driving oil cylinder 6 to pull core-pulling slide block 5 to move remaining stroke.Particularly, core-pulling slide block 5 is provided with the first wedge 11, the second wedge 12 is installed with in the outer ledge lower end of dynamic model cage plate 2, the inclined-plane of the first wedge 11 and the second wedge 12 matches, when mould die sinking, dynamic model cage plate 2 moves, under ramp effect, core-pulling slide block 5 level moves right one section of slight distance, thus completes prizing core-pulling slide block 5.
In order to avoid core-pulling slide block 5 prize time, rigid interference is caused to driving oil cylinder 6, core-pulling slide block 5 adopts with slide block backboard 8 and is flexibly connected, namely be flexibly connected by existing pull bar connector between core-pulling slide block 5 with slide block backboard 8, there is free gap 10 each other and can relative movement, the size of this free gap 10 is 10mm, wherein, the slight distance prizing formation to core-pulling slide block 5 by wedge structure is 6mm, thus, when mould die sinking, core-pulling slide block 5 prizes the slight distance of generation can not the piston rod action of positive drive oil cylinder 6.
Because the temperature of dynamic model cage plate 2 is higher, driving the sealing device of oil cylinder 6 to protect, driving between oil cylinder 6 at cover half cage plate 2 and two and being provided with thermostable heat insulation plate 13.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-mentioned embodiment, in the ken that described technical field those of ordinary skill possesses, various change can also be made under the prerequisite not departing from the utility model aim.
