Abstract
The utility model relates to an interior core pulling mechanism of a sand core mould for casting, which is used for demoulding for the sand core mould. The interior core pulling mechanism comprises a moving mould and a static mould, wherein an interior pulling core is arranged on the static mould and is connected with an open and close mechanism; the open and close mechanism comprises an air cylinder, as well as a locked mould connection block, an interlock block, a pulling core connection block and a connecting bar that are connected with the air cylinder in sequence, wherein the connecting bar is connected with the interior pulling core; a locked-mould pin supporting seat is fixed on the static mould, and a locked-mould pin component is arranged in the supporting seat; racks are arranged on the pulling core connection block, gears meshed with the rack is arranged at two ends of a gear shaft, and the gear shafts are arranged on the static mould by a support. The interior core pulling mechanism can realize the mechanized sand core demoulding, without the process that core assembly and manual core pulling are carried out after the moulding sand core is segregated for demoulding, thereby improving the quality of the sand core, as well as the finished product ratio and the production efficiency of the sand core.
Description
Technical field
The utility model relates to casting technology field, especially relates to the internal core-pulling mechanism of core mold.
Background technology
The product of casting complex structure, the core demoulding is a big problem; Making core at present generally is with core assembly after the core split, looses core with manual; So make, often make surface quality of continuous castings bad, the scrappage height, and also production efficiency is low.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, a kind of internal core-pulling mechanism of foundry sand core mold to be provided, to improve the core quality, improving the yield rate and the production efficiency of core.
For achieving the above object, the technical solution of the utility model is such: a kind of internal core-pulling mechanism of foundry sand core mold, dynamic model, quiet mould are arranged, and on quiet mould, be fixed with quiet mould and insert, during quiet mould is inserted inner core pulling is installed, this inner core pulling connects clasp mould mechanism; Said clasp mould mechanism comprises and is fixed in two cylinders that are symmetrically arranged on the quiet mould, two locked mode coupling blocks that connect with the piston rod of cylinder respectively, can contact the linked block that connects with the locked mode coupling block, the coupling block of loosing core that connects with linked block, and the connecting rod that connects with the coupling block of loosing core, this connecting rod and inner core pulling link; On quiet mould, also be fixed with the locked mode pin mount, the locked mode pin assemblies is installed in the mount pad; This locked mode pin assemblies is by having the spring of installing on the locked mode pin of carving piece, the locked mode pin, and forms at guide that can cooperate with the locked mode pin that is provided with on the quiet mould and the piece of carving that piece matches of carving with on the locked mode pin that is being provided with on the locked mode coupling block; For two coupling blocks of loosing core that guarantee symmetry are synchronized with the movement, on two coupling blocks of loosing core, respectively be provided with tooth bar, be located at the gear shaft two ends with the tooth bar meshed gears, this gear shaft is installed on the quiet mould by bearing.
The course of work of the present utility model is such: during beginning inner core pulling die sinking action, dynamic and static mould still is in the matched moulds state; Under the cylinder of two synchronization actions drives, the motion of locked mode coupling block, the locked mode pin is two carving under the effect of piece axial thrust load of matching, the compression spring, the locked mode pin is pulled away from guide, and this moment, inner core pulling began die sinking, by contact the linked block action that connects with the locked mode coupling block, the drive coupling block of loosing core, loose core coupling block drivening rod and inner core pulling are again finished the die sinking of loosing core; After the inner core pulling die sinking, just dynamic model and quiet mould are opened from, core is stayed on the dynamic model, removes core again; Then during coremaking, drive the locked mode coupling block by cylinder and move to opposite direction along die sinking, the piece of carving on the locked mode coupling block separates with the piece of carving on the locked mode pin at this moment; In the motion of locked mode coupling block, contact the linked block movement therewith that connects with the locked mode coupling block, thereby drive the coupling block of loosing core, loose core coupling block drivening rod and inner core pulling again carry out matched moulds; Then the locked mode pin inserts in the guide under the effect of spring force, and matched moulds is finished, to the coremaking of mould injection sand.
Owing to adopted technique scheme, the internal core-pulling mechanism of a kind of foundry sand core mold of the present utility model has realized the mechanization of the core demoulding, has not been required to be the demoulding and looses core with core assembly after the core split and with manual, so can improve the core quality, improve the yield rate and the production efficiency of core.
