Background technology:
At present, known mould is the design feature design single-casting mould according to workpiece.Press mould drawing casting mould blank during making, be machined to casted die mould then.Earlier workpiece is rolled into the steel plate cone, compression moulding on mould then before the die mould.The casting of mould, machined cycle are long, and expense is high.Be not suitable for the production of the curved circular ring of little, many specifications, making duration weak point in batches.
Summary of the invention:
In order to solve the deficiency of existing prior art, the utility model provides a kind of large-scale curved circular ring plug-in segmentation casted die mould that can be plug-in fast.
A kind of large-scale curved circular ring plug-in segmentation casted die mould, comprise top die and dip mold; Its special character is: said last press mold location-plate by circular arc in the band is provided with the top die flat board through last press mold molded lines plate and forms; All fit together on the last press mold location-plate of said upward press mold molded lines plate and the interior circular arc of band through mounting groove; The top die flat board is welded on the last press mold location-plate of circular arc in the band; Said lower pressed film location-plate by the band external arc is provided with the lower pressed film flat board through lower pressed film molded lines plate and forms; All fit together through mounting groove on the lower pressed film location-plate of lower pressed film molded lines plate and band external arc, the dip mold flat board is welded on the lower pressed film location-plate of band external arc.
The large-scale curved circular ring plug-in segmentation casted die mould of the utility model; The making of last press mold is that the last press mold location-plate of being with interior circular arc is provided with on the top die flat board through last press mold molded lines plate; The making of lower pressed film is that the lower pressed film location-plate of band external arc is provided with the lower pressed film flat board through lower pressed film molded lines plate; On upper and lower press mold location-plate and the molded lines plate unified mounting groove is arranged, so that the plug-in mounting location, and the other end of molded lines plate is welded on the pressing mold flat board.
Be provided with the workpiece blank location-plate in the side of said dip mold, the effect that presses down workpiece location-plate on the mould is the die mould position of fixation workpiece, to guarantee the uniformity of workpiece die mould; All also be provided with backing plate on the location-plate of said upper and lower pressing mold, the effect of backing plate is to make workpiece die mould face rounding off between upper and lower pressing mold and the workpiece.The two ends of said dip mold are provided with resilience adjustment plate, and the effect of resilience adjustment plate is the radial dimension of control die mould workpiece, highly control workpiece die mould springback capacity through regulating stretching out of plate of resilience adjustment, thereby guarantee the radial dimension precision of workpiece.
The utility model is by the assembled casted die mould of steel plate, thereby has simple in structurely, easy to make, and the process-cycle is short in light weight, and expense is low, the process-cycle is short, the characteristics of the curved circular ring profile slyness of compacting.
