Description
Technical field
This utility model relates to mold machining technology field, more specifically, relating to a kind of pressure with newel magnetic core
Molding jig.
Background technology
A kind of sintering magnetic metal oxide that magnetic core is made up of various iron oxide mixture, conventional magnetic core is ferrite
Magnetic core, and FERRITE CORE is commonly used in coil and the transformator of various electronic equipment.FERRITE CORE is adding man-hour
Generally use the mode of compacting to be shaped, and when compressing, particulate material need to be put into and press is pressed into green compact,
Then molding it is fired.It is said that in general, the biggest pcrmeability of the density of green compact is the highest, thus, the green compact being pressed into
Density size directly influences the pcrmeability of FERRITE CORE.For the magnetic core with newel, newel is the magnetic line of force
Main thoroughfare, thus the magnetic core with newel is the strictest to the density requirements of green compact.
Typically the mould with newel magnetic core is plane, this mould when filler often filler uneven, and then make
Obtaining green density and do not reach requirement, the magnetic permeability produced is on the low side, and performance is difficult to reach to apply requirement.
Utility model content
The purpose of this utility model is to provide a kind of compacting tool set with newel magnetic core, solves filling out described in background technology
The problem that during material, green density is low.
In order to solve above-mentioned technical problem, this utility model following technical scheme of offer:
A kind of compacting tool set with newel magnetic core, described compacting tool set includes mo(u)ld top half mould and mo(u)ld bottom half mould, described under
It is provided with on mould on centre bore, and the sidewall of described centre bore and is provided with strip projection.
Preferably, described strip projection highlights the side wall surface 0.2-0.3mm of described centre bore.
Preferably, described mo(u)ld bottom half mould is additionally provided with the first side opening and the second side opening, described first side opening and described second
The both sides being distributed in described centre bore that side opening is symmetrical.
Preferably, described mo(u)ld bottom half mould is additionally provided with screw hole.
Preferably, described mo(u)ld top half mould and described mo(u)ld bottom half mould are flexibly connected.
This utility model provides a kind of compacting tool set with newel magnetic core, described compacting tool set include mo(u)ld top half mould and
Mo(u)ld bottom half mould, described mo(u)ld bottom half mould is provided with centre bore, the sidewall of described centre bore is provided with strip projection.This reality
With the compacting tool set of novel offer by arranging strip projection on the sidewall of centre bore so that compacting tool set is accelerating filler
During speed, the air in centre bore can be completely exhausted out along strip projection, so that filler is abundant, and then improves magnetic
The density of core green compact, improves production efficiency.

Detailed description of the invention
The purpose of this utility model is to provide a kind of compacting tool set with newel magnetic core, solves filling out described in background technology
The problem that during material, green density is low.
For the technical scheme making those skilled in the art be more fully understood that in this utility model embodiment, and make this practicality
The above-mentioned purpose of new embodiment, feature and advantage can become apparent from understandable, real to this utility model below in conjunction with the accompanying drawings
The technical scheme executed in example is described in further detail.
Refer to accompanying drawing 1, accompanying drawing 1 shows the compacting tool set with newel magnetic core that this utility model embodiment provides
Structural representation.From accompanying drawing 1 it can be seen that this utility model provide the compacting tool set bag with newel magnetic core
Include mo(u)ld top half mould 1 and 2 two parts of mo(u)ld bottom half mould, mo(u)ld top half mould 1 and mo(u)ld bottom half mould 2 by hinged, link or cover
Mode be flexibly connected, additionally, mo(u)ld top half mould 1 and mo(u)ld bottom half mould 2 can also be by being arranged on the spiral shell on mo(u)ld bottom half mould 2
Silk hole 7 is flexibly connected.When compacting is with the magnetic core of newel, first filler is inserted in mo(u)ld bottom half mould 2, then will
Mo(u)ld top half mould 1 is suppressed after covering, and obtains the magnetic core green compact with newel.
Refer to accompanying drawing 2, the mo(u)ld bottom half mould 2 of the compacting tool set with newel magnetic core that this utility model embodiment provides
On be provided with centre bore 3, the sidewall of centre bore 3 is provided with strip projection 4.By filler being inserted centre bore 3 warp
The newel of magnetic core is obtained after crossing compacting.The strip projection 4 arranged on the sidewall of centre bore 3 enables to compacting tool set and exists
When accelerating filler speed, the air in centre bore 3 can be completely exhausted out along strip projection 4, so that filler is abundant,
And then improve the density of magnetic core green compact.Owing to accelerating fast filler speed, so that production efficiency is also improved.
Concrete, refer to accompanying drawing 3.During strip projection 4 on the compacting tool set that this utility model embodiment provides highlights
The side wall surface 0.2-0.3mm of central hole 3, length and the width of strip projection 4 set with the diameter of centre bore 3.Due to
The strip projection 4 on the compacting tool set with newel magnetic core that this utility model embodiment provides sets, thus is suppressed
The groove of 0.2-0.3mm is had on the newel of the magnetic core green compact gone out.But, magnetic core green compact are also wanted after ablating work procedure terminates
The magnetic core produced carries out polishing process, and the 0.6-0.8mm on minimum magnetic core surface to be ground off when polishing, thus, make
It is final that the magnetic core that the compacting tool set with newel magnetic core provided by this utility model embodiment is suppressed does not interferes with it
Use.
