Abstract
The invention discloses a middle mold core for manufacturing a large mold. The mold core is formed by splicing various blocks. The middle mold core has the advantages that the mold core is formed by splicing the blocks into a whole, after the mold is stressed, the spliced mold core has the buffering function and has less possibility of being cracked and damaged, and the scrap rate of the mold core is reduced; and when the mold core is worn in the pressing process, only the worn blocks are required to be replaced or the blocks are required to be spliced into a full mold core so as to form a cavity, the mold core still can be utilized, and the cost is reduced.
Description
Technical field
The present invention relates to a kind of core rod for the manufacture of mould, particularly a kind of middle mould core rod for the manufacture of large mold.
Background technology
Tradition core rod be whole wolfram steel and outer construction materials contract are set in hot jacket or the method for colding pressing together with.For middle-size and small-size mould manufacture, it is extraordinary method, but manufacture for very large mould, the method is because mold weight is large, easily making material is that the pressure that the core rod of wolfram steel is subject to ftractures greatly, cause mould to be scrapped, and once the core rod wearing and tearing of monoblock just can not be repaiied in pressing process, can only integral replacing.
Summary of the invention
Goal of the invention: for the problems referred to above, the object of this invention is to provide a kind of middle mould core rod that is applicable to manufacture large mold, reduce scrap, cost-saving.
Technical scheme: a kind of middle mould core rod for the manufacture of large mold, described core rod is spelled and formed mutually by each piecemeal.
Beneficial effect: compared with prior art, advantage of the present invention is that core rod is to be combined into mutually integral body by each piecemeal, after mould is stressed, has cushioning effect between the core rod of spelling mutually, and core rod damage not easy to crack has reduced the learies of core rod; In pressing process, core rod wearing and tearing, do die cavity again as long as change the piecemeal of wearing and tearing or be again combined into mutually full core rod, and core rod still can utilize, and reduces cost.
Accompanying drawing explanation
Accompanying drawing is structural representation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment is only not used in and limits the scope of the invention for the present invention is described, after having read the present invention, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in drawings, a kind of middle mould core rod for the manufacture of large mold, described core rod is combined into core rod integral body mutually by tungsten steel block 1, tungsten steel block 2, tungsten steel block 3, tungsten steel block 4.
Under weight, between each tungsten steel block, power has buffering, and each tungsten steel block is not easy to crack, and middle mould in use only need do outsourcing 5 again if any wearing and tearing, the recycling splicing of core rod, then do die cavity, and increase the utilization to wolfram steel, reduce cost.
Manufacturing process is: first each tungsten steel block that forms core rod is processed, be spliced into mutually each other core rod shape, then make outsourcing, outsourcing and core rod are nested, then do die cavity.
Claims (1)
1. for the manufacture of a middle mould core rod for large mold, it is characterized in that: described core rod is spelled and formed mutually by each piecemeal.
