Abstract
The utility model discloses a kind of compound material feeding magnetic core molds of multiple flow passages, the upper mold of the die cavity above die cavity backing plate and stacking above die cavity is set to including die cavity backing plate, stacking, the die cavity includes the distribution of rectangular array shape and die cavity hole array up and down, the die cavity backing plate corresponds to die cavity hole and is equipped with the pilot hole passed through for formed punch, by laterally expecting hole connection between laterally adjacent two die cavity hole, die cavity hole both lateral sides wall is equipped with the vertical material hole being connected to lateral material hole port, to make laterally all die cavity holes connections.When the utility model is one time punching molded, the stream amount between die cavity hole can be complementary, also can have more consistent density eventually by the one time punching molded magnetic core of the mold.
Description
Technical field
The utility model relates to magnetic core manufacturing technologies, and in particular to magnetic core punch-forming mold.
Background technique
Magnetic core is by mold compression moulding, and in general, multiple die cavity holes can be arranged in mold, while injecting original to die cavity hole
Material, and it is one time punching molded.It is due to material feeding it is difficult to ensure that consistent, cause the density of multiple magnetic cores variant.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of compound material feeding magnetic core mold of multiple flow passages, makes primary
Stamping forming magnetic core can have more consistent density.
In order to solve the above technical problems, the utility model adopts the following technical solution: a kind of compound material feeding magnetic core of multiple flow passages
Mold is set to the upper mold of the die cavity above die cavity backing plate and stacking above die cavity, the mould including die cavity backing plate, stacking
Chamber includes the distribution of rectangular array shape and die cavity hole array up and down, and the die cavity backing plate corresponds to die cavity hole and is equipped with for formed punch
By pilot hole, by laterally expecting hole connection between laterally adjacent two die cavity hole, die cavity hole both lateral sides wall is equipped with and transverse direction
The vertical material hole of hole port connection is expected, to make laterally all die cavity hole connections of a row.
Optionally, the vertical material hole is semicircle orifice.
Optionally, the laterally material hole is greater than semicircle bore dia for the width of flat round hole and flat round hole, is highly greater than semicircle
Pore radius.
Optionally, the upper mold is equipped with the drainage hole penetrated through with die cavity hole.
Optionally, the lower section of the die cavity backing plate is equipped with material pond, and material pond is connected to each die cavity hole.
The technical solution adopted in the utility model has the following beneficial effects: between laterally adjacent die cavity hole by vertically expecting
Hole and laterally material hole intercommunication, simultaneously because die cavity hole is connected to material pond, therefore by vertically expecting hole and all mold core holes of material pond
All be connection, thus it is one time punching molded when, the stream amount between die cavity hole can be complementary, eventually by punching press of the mold
Molding magnetic core also can have more consistent density.
The specific technical solution and its advantages of the utility model will combine attached in the following detailed description
Figure is described in detail.
Detailed description of the invention
The utility model is further described with reference to the accompanying drawings and detailed description:
Fig. 1 is the planar structure schematic diagram of the utility model die cavity；
Fig. 2 is the horizontal cross-section structure diagram of the utility model die cavity.
Specific embodiment
The technical solution of the utility model embodiment is explained below with reference to the attached drawing of the utility model embodiment and
Illustrate, but following embodiments are only the preferred embodiment of the utility model, and not all.Based on the implementation example in the implementation mode,
Those skilled in the art's obtained other embodiments without making creative work, belong to the utility model
Protection scope.
Referring to fig. 1 and fig. 2, the compound material feeding magnetic core mold of a kind of multiple flow passages, including die cavity backing plate, stacking are set to die cavity
Die cavity 1 above backing plate and stacking are set to the upper mold above die cavity, and the die cavity includes rectangular array shape distribution and up and down
11 array of die cavity hole of perforation, the die cavity backing plate correspond to die cavity hole and are equipped with the pilot hole passed through for formed punch, laterally adjacent two mould
Pass through between cavities and laterally expect that hole 12 is connected to, die cavity hole both lateral sides wall is equipped with the vertical material hole being connected to lateral material hole port
13, to make laterally all die cavity hole connections of a row, the lower section of the die cavity backing plate is equipped with material pond, and material pond and each die cavity hole connect
It is logical.Due to being fed using material pond formula, multiple flow passages are distributed material feeding design, it is ensured that material feeding is uniform, simultaneously because laterally adjacent mould
By vertically material hole 13 and laterally material 12 intercommunication of hole between cavities, and die cavity hole is connected to material pond, thus by vertically material hole and
All mold core holes of material pond are also all connections, thus it is one time punching molded when, the stream amount between die cavity hole can be complementary, final logical
Crossing the one time punching molded magnetic core of the mold also can have more consistent density.
Wherein, the vertical material hole is semicircle orifice, in order to machining.The laterally material hole is flat round hole and flat round hole
Width be greater than semicircle bore dia, highly be greater than semicircle pore radius, therefore between laterally adjacent two die cavity hole stream may be implemented it is suitable
It is smooth complementary.
In addition, the upper mold is equipped with the drainage hole penetrated through with die cavity hole, the moisture generated during press fitting can be discharged,
Guarantee Forming Quality.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, being familiar with the those skilled in the art should be understood that the utility model includes but is not limited to attached drawing and specific embodiment party above
Content described in formula.The modification of any function and structure principle without departing from the utility model is intended to be included in claims
Range in.
