Abstract
The utility model provides a mold device for preparing pure-nickel hollow blank. The mold device comprises a base and a mold body, wherein the base and the mold body are of a split structure and are fixedly connected with each other to form a whole body; a ceramic locating device is arranged at the middle part of the upper end face of the base; a tubular ceramic mold core is disposed in a mold cavity, and the lower end of the tubular ceramic mold core is sleeved on the ceramic locating device so as to be located; and the upper end of the tubular ceramic mold core is provided with a ceramic end cover. When the device is put into use, an ingot is solidified in a vacuum induction melting furnace before being discharged, and is naturally cooled after being de-molded, the tubular ceramic mold core and the ceramic locating device shrink and break due to the cooling of the ingot, and the hollow ingot is formed after ceramic shards are removed; with the adoption of the mold device, the problem of poor cold processing property of nickel is solved; and the outer circle of the ingot is polished and then an inner hole is directly polished without drilling at the center of the ingot, and thus not only are the production efficiency and the yield improved, but also the production cost is effectively reduced.
Description
Technical field
The utility model relates to a kind of die device for the preparation of the pure nickel hollow blank.
Background technology
At present when preparation pure nickel hollow blank, usually adopt extrusion to finish, extrusion billet generally adopts vacuum induction melting, is cast as first circular ingot casting, cools off come out of the stove rear car light and crop afterbody, drill centers is made extrusion billet, because the cold-forming property of nickel is poor, chip removal difficulty during boring is so that extrusion billet production efficiency is low, yield rate is low and cost is high, therefore is necessary to improve.
The utility model content
The technical problem that the utility model solves: a kind of die device for the preparation of the pure nickel hollow blank is provided, die body and base are that split-type structural and both are connected to one, be shaped with groove and in groove, be provided with ceramic positioner at middle part, base upper surface, tubular ceramic core rod lower end is sleeved on the ceramic positioner, tubular ceramic core rod upper end is provided with end cap, thereby causes tubular ceramic core rod and the broken hollow cast ingot that forms of ceramic positioner because of the cooling contraction after the nickel solution cast.
The technical solution adopted in the utility model: for the preparation of the die device of pure nickel hollow blank, have base and die body, described base and die body are that split-type structural and both are connected to one, middle part, described base upper surface is provided with ceramic positioner, the tubular ceramic core rod places in the die cavity and its lower end is sleeved on the ceramic positioner and locates, and described tubular ceramic core rod upper end is provided with ceramic end cap.
Further, middle part, described base upper surface is shaped with groove, and described ceramic positioner lower end is fixed in the groove, and ceramic positioner upper end is suitable with tubular ceramic core rod lower end.
Further, be shaped with connecting hole on the described base, described die body bottom face is shaped with screwed hole, and bolt passes connecting hole and screwed hole screws.
The utility model compared with prior art solves the poor difficult problem of nickel cold-forming property, need not in ingot casting centre-drilling hole, direct car behind the ingot casting cylindrical car light is gone out endoporus get final product, and not only enhances productivity and yield rate, and effectively reduces production costs.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Below in conjunction with accompanying drawing 1 a kind of embodiment of the present utility model is described.
Die device for the preparation of the pure nickel hollow blank, have base 1 and die body 2, described base 1 and die body 2 is connected to one for split-type structural and both, specifically, be shaped with connecting hole 7 on the described base 1, described die body 2 bottoms are shaped with screwed hole 8, and bolt 10 passes connecting hole 7 and screws with screwed hole 8.Middle part, described base 1 upper surface is provided with ceramic positioner 3, tubular ceramic core rod 4 places in the die cavity 9 and its lower end is sleeved on location on the ceramic positioner 3, specifically, middle part, described base 1 upper surface is shaped with groove 6, described positioner 3 lower ends are fixed in the groove 6, and ceramic positioner 3 upper ends and tubular ceramic core rod 4 lower ends are suitable; Described tubular ceramic core rod 4 upper ends are provided with ceramic end cap 5, and nickel solution enters tubular ceramic core rod 4 inner chambers when preventing from pouring into a mould.
When adopting this device, ingot casting is come out of the stove after solidifying in vacuum induction melting furnace, naturally cooling after the demoulding, tubular ceramic core rod 4 and ceramic positioner 3 be because the cooling of ingot casting is shunk breaks, with the potsherd removal hollow cast ingot; Solved the poor difficult problem of nickel cold-forming property, need not in ingot casting centre-drilling hole, direct car behind the ingot casting cylindrical car light has been gone out endoporus get final product, not only enhanced productivity and yield rate, and effectively reduce production costs.
Above-described embodiment is preferred embodiment of the present utility model, is not to limit the utility model practical range, so all equivalences of being done with the described content of the utility model claim change, all should be included within the utility model claim scope.
