Abstract
The utility model discloses a magnetic core pressing mould device. Two concave grooves are arranged at the bottom of a mould, and a concave groove is arranged in the middle of the top portion of the mould. According to the magnetic core pressing mould device, not only is the production cost reduced, but also the contact area between the bottom of a magnetic core and a bearing burning plate is enabled to be reduced when the magnetic core is sintered, and therefore occurrence probability of crystallization of the bottom of the magnetic core is reduced, and occurrence probability of cracking of the magnetic core when the magnetic core is sintered is also reduced.
Description
Technical field
The utility model relates to a kind of pressing mold device, is specifically related to a kind of magnetic core compacting die device.
Background technology
At present, aspect the magnetic core compacting die device, moulding process between each company is different, particularly a lot of companies are after product restructuring, it is relatively chaotic that a lot of companies product changes Postforming Technology over to, and do not embody in original mould in the progress of mould-forming process, each company's mould therefor also all is to continue use by original technique.But find by the lot of experiments in producing, the product of magnetic core compacting die institute moulding originally, in the sintering process afterwards, the occurrence probability of crystallization and cracking is higher, has a strong impact on the quality of product.
The utility model content
Provide a kind of novel magnetic core compacting die device for addressing the above problem the utility model, in the production process of reality, not only reduced production cost, and the incidence of crystallization and cracking when reducing sintering.
The purpose of this utility model is achieved through the following technical solutions:
A kind of magnetic core compacting die device, the bottom of described mould are provided with two grooves, are provided with a groove in the centre at the top of described mould.
Preferably, two of described bottom grooves are parallel to each other and are symmetrically distributed in the both sides of described bottom.
The beneficial effects of the utility model are: all increase groove by top and bottom at mould, the bottom reduces with the contact area of load bearing board when making the magnetic core sintering, thereby reduce the occurrence probability of bottom crystallization, the occurrence probability that has ftractureed when also having reduced sintering has reduced the production cost of product.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
The present invention is described in detail below in conjunction with specific embodiment.Following examples will help those skilled in the art further to understand the present invention, but not limit in any form the present invention.Should be pointed out that to those skilled in the art, without departing from the inventive concept of the premise, can also make some distortion and improvement.These all belong to protection scope of the present invention
Magnetic core compacting die device as shown in Figure 1 is provided with left groove 1 and the right groove 2 of two described two bottom sides that are parallel to each other and are symmetrically distributed in the bottom of mould, the centre at the top of mould is provided with groove 3.
Passed through repeatedly experiment, do not affect in line with the process adjustment under the principle of finished product outward appearance and electrical property, the maximum F of the product that the mould model that need are changed is produced is benchmark, calculates stock removal, thereby draws best groove slotting position and depth of groove.
The utility model is based on several current conditions: can not increase burden to production behind (1), the fluting, not increase and reduced on the contrary production cost; (2), the properties to magnetic core can not exert an influence behind the fluting; (3), all magnetic cores all need to carry out grinding behind sintering; (4), magnetic core crystallization and cracking are the topmost factors that affects product quality during sintering.
In the production application process of reality, the utility model has not only reduced production cost, and reduce with the load bearing board contact area magnetic core bottom when making the magnetic core sintering, thereby has reduced bottom crystallization odds, the occurrence probability that has ftractureed when also having reduced sintering.
Claims (2)
1. magnetic core compacting die device is characterized in that: be provided with two grooves in the bottom of described mould, be provided with a groove in the centre at the top of described mould.
2. magnetic core compacting die device according to claim 1 is characterized in that: two grooves of described bottom are parallel to each other and are symmetrically distributed in the both sides of described bottom.
