The utility model provides an embossing mold utensil is protruding through setting up the screw thread form on the inside wall at left side mould and right side mould for the embossing mold utensil is when accelerating filler speed, and the air in embossing mold possesses can be discharged along the screw thread form is protruding completely, thereby makes the filler abundant, and then improves the density of magnetic core unburned bricks, improves production efficiency.
Description
Technical field
This utility model relates to mold machining technology field, more specifically, relating to a kind of U-shaped magnetic core compacting die.
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 CORE, and FERRITE CORE is commonly used in coil and the transformator of various electronic equipment.FERRITE CORE generally uses the mode of compacting to be shaped adding man-hour, and when compressing, particulate material need to be put into and be pressed into green compact in press, is then fired molding.It is said that in general, the biggest pcrmeability of the density of green compact is the highest, thus, the density size of the green compact being pressed into directly influences the pcrmeability of FERRITE CORE.
General magnetic core mould is plane, this mould when filler often filler uneven, and then make green density 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 U-shaped magnetic core compacting die, solves the problem that during filler described in background technology, green density is low.
In order to solve above-mentioned technical problem, this utility model following technical scheme of offer:
A kind of U-shaped magnetic core compacting die, described U-shaped magnetic core compacting die includes that left side mould and right side mould, described left side mould and described right side mould are symmetrical structure, and is respectively provided with screw-like projection on the medial wall of described left side mould and described right side mould.
Preferably, described screw-like projection highlights described left side mould and the side wall surface 0.2-0.3mm of described right side mould.
Preferably, the first side wall of described right side mould is higher than the second sidewall of described right side mould.
Preferably, described screw-like projection is arranged on the inwall of described the first side wall.
Preferably, described left side mould and right side mould are flexibly connected.
This utility model provides a kind of U-shaped magnetic core compacting die, and described U-shaped magnetic core compacting die includes that left side mould and right side mould, described left side mould and described right side mould are symmetrical structure, and is respectively provided with screw-like projection on the medial wall of described left side mould and described right side mould.The compacting tool set that this utility model provides is by being threaded shape projection on the medial wall of left side mould and right side mould, make compacting tool set when accelerating filler speed, air in centre bore can be completely exhausted out along screw-like projection, so that filler is abundant, and then the density of raising magnetic core green compact, improve production efficiency.

Detailed description of the invention
The purpose of this utility model is to provide a kind of U-shaped magnetic core compacting die, solves the problem that during filler described in background technology, 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 it is understandable to enable the above-mentioned purpose of this utility model embodiment, feature and advantage to become apparent from, below in conjunction with the accompanying drawings the technical scheme in this utility model embodiment is described in further detail.
Refer to accompanying drawing 1 and accompanying drawing 2, accompanying drawing 1 and accompanying drawing 2 and respectively illustrate left side mould and the three-dimensional structure diagram of right side mould of the U-shaped magnetic core compacting die that this utility model embodiment provides.From accompanying drawing 1 and accompanying drawing 2 it can be seen that this utility model provide U-shaped magnetic core compacting die include left side mould 1 and 2 two parts of right side mould, left side mould 1 and right side mould 2 by hinged, link or cover by the way of be flexibly connected.When suppressing magnetic core, after first left side mould 1 and right side mould 2 being connected, then filler inserted in mould and suppress, obtaining magnetic core green compact.
Refer to accompanying drawing 2, it is threaded shape projection 3 on the medial wall of the right side mould 2 of the U-shaped magnetic core compacting die that this utility model embodiment provides, set screw-like projection 3 enables to compacting tool set when accelerating filler speed, air in the mould 2 of right side can be completely exhausted out along screw-like projection 3, 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 and accompanying drawing 4.Interior sidewall surface 0.2-0.3mm of the screw-like projection 3 prominent right side mould 2 on the compacting tool set that this utility model embodiment provides, length and the width of screw-like projection 3 set with length and the width of right side mould 2.Owing to the screw-like projection 3 on the U-shaped magnetic core compacting die that this utility model embodiment provides sets, thus on the lateral wall of the magnetic core green compact suppressed, there is the groove of 0.2-0.3mm.But, magnetic core green compact also to carry out polishing processing after ablating work procedure terminates to the magnetic core produced, and the 0.6-0.8mm on minimum magnetic core surface to be ground off when polishing, thus, the magnetic core that the U-shaped magnetic core compacting die using this utility model embodiment to provide is suppressed does not interferes with its final use.
Further, in the U-shaped magnetic core compacting die that this utility model embodiment provides, the first side wall 4 of right side mould 2 is higher than the second sidewall 5 of right side mould 2.Owing to right side mould 2 and left side mould 1 are symmetrical structures, therefore, two Sidewall Height of left side mould 1 are also different, and its height is corresponding to the first side wall in right side mould 24 and the height of the second sidewall 5.
Further, being prone to separate from compacting tool set after being pressed into green compact for ease of U-shaped magnetic core, screw-like projection 3 is arranged on the inwall of the first side wall 4.
Although having described this utility model in the way of specific embodiment, but to those skilled in the art, in the case of the spirit and scope of the present utility model limited without departing from appended claims, this utility model can be carried out variations and modifications, these change and modifications and are also included in the range of this utility model.
