Abstract

The utility model discloses a forming die with carbide material preparation mould core bar belongs to electronic component basic magnetic material product and makes technical field. The utility model discloses an improvement on the used forming die basis of magnetic blank product is made to prior art. The improvement point is mainly characterized in that one end of a mold core rod is made into an external thread structure, in addition, a hard alloy material is used for making an alloy core with an internal thread structure, the alloy core is connected with the external thread of the thread end of the core rod, and meanwhile, a female mold alloy is embedded in the inner wall of a through hole of a female mold, so that the magnetic powder slurry is in direct contact with the alloy core and frequently moves in the process of pressing the magnetic powder slurry into a blank product in a forming mold. Due to the characteristic of hardness of the hard alloy material, the abrasion of the alloy core is effectively reduced, the precision of a formed blank product is ensured, the product quality is improved, and the service life of the die is prolonged.

Description

A kind of mould of making the mould core bar with Hardmetal materials
Technical field
The utility model relates to a kind of mould, relates in particular to a kind of mould with Hardmetal materials making mould core bar, belongs to electronic devices and components manufacturing technology field.
Background technology
Adopting magnetic material to make different, the variform magnetic product of all size to satisfy the market demand of industries such as telecommunications, household electrical appliances, automobile making, is the duty-bound duty duty of magnetic material manufacturing.Along with science and technology development, magnetic product not only range of application is more and more wider, and also increasingly high to its required precision.As everyone knows; Adopt the magnetic raw material to manufacture the magnetic product of different size, shape; Its common technological process be through will constitute put together after various raw material that the magnetic product desired properties requires dispose according to a certain percentage pulverize, operation such as stirring processes slip; Be pressed into the blank product through the mould that required product shape, specification requirement are installed again, and then form through operation manufacturings such as oversinterings.Therefore, for the required precision of the quality and the size of magnetic product, it is particularly important that the required precision of slug press product just seems.In the prior art, make the core bar in the magnetic blank formed product mould, its material generally all adopts ordinary steel to process.Because magnetic powder slip is processed in the process of blank product at mould inner pressure, the moving around in the mould die cavity of its core bar is the most frequent, thereby the wearing and tearing that receive are also the fastest.The direct result that the wearing and tearing of core bar cause is that the blank product precision that compacting is come out reduces, and then influences product quality.
Summary of the invention
For solving the problem of above-mentioned existence, the utility model provides a kind of mould that adopts Hardmetal materials to make the mould core bar.Adopting this mould, is directly to be contacted with magnetic powder slip by the die alloy that alloy fuse and die through-hole wall are inlayed in slug press product process, and the alloy fuse moves up and down in magnetic powder slip to each product compacting completion.Because the alloy fuse is processed by Hardmetal materials, the rockiness characteristics that itself had effectively reduce the wearing and tearing of core bar in mould, have guaranteed the precision of molded blank product, the service life of having improved mould simultaneously.This Hardmetal materials is made the mould of mould core bar and realized through following technical scheme: a kind of mould with Hardmetal materials making mould core bar mainly comprises patrix, die, counterdie and core bar.Patrix is a punch structure, and die is that the inwall of through-hole structure and through hole is inlayed the die alloy that uses alloy material to make.The external diameter of patrix equals the internal diameter of die alloy.Counterdie is punch and is through-hole structure.Core bar passes the through hole of counterdie, and its end in the type sky is provided with external thread structure.The alloy fuse of being processed by alloy material is a female thread structure, between the end of thread of alloy fuse and core bar through being threaded.The external diameter of counterdie equals the internal diameter of die alloy, and counterdie is arranged in the through hole of die alloy and is slidingly connected.The position of counterdie in the die holes constitutes the space size of die cavity, and the size in die cavity space depends on the specification size of the magnetic blank product of manufacturing.That is to say that the space size of die cavity can be confirmed by the position of counterdie in the die holes.In magnetic powder slip injected die cavity, through the mobile blank product that is pressed into of upper and lower mould, the alloy fuse withdrawed from the compacting of mould type blank product and accomplishes.Being pressed in the process of blank product by magnetic powder slip whole, is directly to be contacted and repeated moving is accomplished up to blank product compacting by alloy fuse and magnetic powder slip.Because the rockiness characteristics that alloy material itself is had, thereby strengthened the wearability of mould core bar in mould greatly.The precision that has guaranteed the molded blank product has improved product quality, has prolonged the service life of mould.
As preferably: the thickness of the said alloy fuse of being processed by Hardmetal materials with female thread structure is 1~2mm.
As preferably: the thickness of the die alloy that said die through-hole wall is inlayed is 0.5~1mm.
Description of drawings
Fig. 1 adopts Hardmetal materials to make the structural representation of mold core bar mould.
The specific embodiment
Below in conjunction with accompanying drawing 1, provide embodiment to the utility model, this technical scheme is further specified.
Embodiment 1: like Fig. 1, and a kind of mould of making the mould core bar with Hardmetal materials.Mainly by patrix 1, die 3, counterdie 2, core bar 4 constitutes.Said patrix 1 is a punch structure, and die 3 is inlayed the die alloy of being made by alloy material 5 for through-hole structure and at the inwall of through hole, and patrix 1 external diameter equals the internal diameter of die alloy 5; Counterdie 2 is for punch and be through-hole structure; The external diameter of core bar 4 equals the internal diameter of counterdie 2 through holes and flexibly connects; Core bar 4 passes the through hole of counterdie 2 and places in the through hole of die alloy 5; The end of core bar 4 in die alloy 5 through holes is arranged to external thread structure, and alloy fuse 6 is a female thread structure, between the male end of alloy fuse 6 and core bar 4 through being threaded.The through hole of die alloy 5, alloy fuse 6 and counterdie 2 position in die alloy 5 through holes constitutes the space size of die cavity, and the size of die cavity can be confirmed according to the size of the blank product of required compression moulding.After in die cavity, injecting magnetic powder slip by the compacting of the mobile completion blank product of patrix 1, counterdie 2.Core bar 4 shifts out die cavity then.The compacting of blank product is accomplished, and moves in circles with this.Be that alloy fuse 6 by core bar 4 ends of thread contacts with the direct repeated moving of magnetic powder slip in whole pressing process.Because alloy fuse 6 is to be processed by alloy material; And the rockiness characteristics that alloy material itself is had; Strengthened the wearability of the alloy fuse 6 that is threaded with core bar 4 in the mould greatly; Guarantee the required precision of molded blank product, improved the molded blank product quality, prolonged the service life of mould.
