The utility model discloses a kind of ferrite die-sinking die devices, it includes upper die holder and lower die holder, the upper die holder and lower die holder docking setting, the upper die holder offers model cavity, drag chamber is offered on the lower die holder, the upper model cavity docks setting with drag chamber, the intracavitary forming blocks being provided in " recessed " shape of the drag, center pillar slot is offered in the middle part of the forming blocks, the drag chamber offers forming tank in forming blocks two sides respectively, and the bottom face of the center pillar slot is higher than the bottom face of forming tank.The utility model passes through in the intracavitary setting forming blocks of drag, it is higher than the height of forming tank using the height of the center pillar slot of forming blocks, so that the two sides socle length of ferrite green compact after molding is greater than the length of center pillar, reduce the number of operations that ferrite green compact need center pillar additionally to be polished after shaping, reduce the operating time during ferrite green compact subsequent forming, the production efficiency of ferrite green compact is improved, and then is increased economic efficiency.
Description
Technical field
The utility model relates to a kind of mould structures, more particularly, to a kind of ferrite die-sinking die device.
Background technique
Soft magnetism industrial circle, normal the used mold design of ferrite production, to sintered ferrite product quality
Influence is very big, and traditional mold is after die cast ferrite green compact, so that the center pillar of ferrite green compact and side socle height one
It causes, causes to increase workload when carrying out subsequent operation to ferrite green compact, be unfavorable for the raising of ferrite green compact production efficiency.
Utility model content
Based on this, it is necessary in view of the deficiencies of the prior art, provide a kind of ferrite die-sinking die device, improve product and burn
Sintering quality after knot guarantees the production efficiency of ferrite product.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: ferrite die-sinking die dress
It sets comprising upper die holder and lower die holder, the upper die holder and lower die holder docking setting, the upper die holder offer model cavity,
Drag chamber is offered on the lower die holder, the upper model cavity docks setting, the intracavitary setting of drag with drag chamber
There are the forming blocks in " recessed " shape, offers center pillar slot in the middle part of the forming blocks, the drag chamber is opened respectively in forming blocks two sides
Equipped with forming tank, the bottom face of the center pillar slot is higher than the bottom face of forming tank.
The forming blocks upper surface is not higher than lower die holder upper surface in one of the embodiments,.
The top end part section of the upper model cavity is convex arc columnar structure in one of the embodiments,.
The distance between drag bottom of chamber end face and upper model cavity top end face are greater than in one of the embodiments,
19mm。
The upper model cavity and the intracavitary die cast of drag have ferrite green compact in one of the embodiments, described
Ferrite green compact include the center pillar that two sides socle is arranged in and is arranged among the socle of both sides.
The height of center pillar 5mm lower than the height of side socle in one of the embodiments,.
In conclusion the utility model ferrite die-sinking die device is by utilizing in the intracavitary setting forming blocks of drag
The height of the center pillar slot of forming blocks is higher than the height of forming tank, so that the two sides socle length of ferrite green compact after molding is big
In the length of center pillar, reduces the number of operations that ferrite green compact need center pillar additionally to be polished after shaping, reduce
Operating time during ferrite green compact subsequent forming, the production efficiency of ferrite green compact is improved, and then increased economic efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model ferrite die-sinking die device；
Fig. 2 is the structural schematic diagram of the utility model ferrite green compact.
Specific embodiment
For the feature, technological means and specific purposes achieved, function that can further appreciate that the utility model, below
The utility model is described in further detail in conjunction with attached drawing and specific embodiment.
As depicted in figs. 1 and 2, the utility model ferrite die-sinking die device includes upper die holder 10 and lower die holder 20, institute
It states upper die holder 10 and the docking setting of lower die holder 20, the upper die holder 10 offers model cavity 11, open up on the lower die holder 20
Have a drag chamber 21, the upper model cavity 11 docks setting with drag chamber 21, the upper model cavity 11 in drag chamber 21
Die cast has ferrite green compact 30, and the ferrite green compact 30 include setting in two sides socle 31 and are arranged in both sides socle
Center pillar 32 among 31.
It is provided with the forming blocks 22 in " recessed " shape in the drag chamber 21, offers center pillar slot in the middle part of the forming blocks 22
23, the drag chamber 21 offers forming tank 24 in 22 two sides of forming blocks respectively, and 22 upper surface of forming blocks is not higher than down
20 upper surface of die holder, the bottom face of the center pillar slot 23 are higher than the bottom face of forming tank 24, so that molding ferrite green compact 30
The length of center pillar 32 is less than 31 length of side socle of two sides, reduces traditional ferrite green compact 30 and needs center pillar after shaping
32 number of operations additionally polished reduce the operating time during 30 subsequent forming of ferrite green compact, improve iron oxygen
The production efficiency of body green compact 30, and then increase economic efficiency.
Specifically, the height of the center pillar 32 5mm lower than the height of side socle 31.
The top end part section of the upper model cavity 11 is convex arc columnar structure, so that the bottom end size meeting of ferrite green compact 30
Increase, to reduce the gap with 30 upper end size of ferrite green compact, effectively prevents 30 die cast of ferrite green compact
Afterwards the case where being inclined outwardly.
The distance between 21 bottom face of drag chamber and upper 11 top end face of model cavity are big in one of the embodiments,
In 19mm.
In conclusion the utility model ferrite die-sinking die device by drag chamber 21 be arranged forming blocks 22,
It is higher than the height of forming tank 24 using the height of the center pillar slot 23 of forming blocks 22, so that the two sides of ferrite green compact 30 after molding
Socle 31 length in side is greater than the length of center pillar 32, reduces ferrite green compact 30 and center pillar 32 is needed additionally to be beaten after shaping
The number of operations of mill reduces the operating time during 30 subsequent forming of ferrite green compact, improves the life of ferrite green compact 30
Efficiency is produced, and then is increased economic efficiency.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to the scope of the utility model.It should be pointed out that for the ordinary skill of this field
