Abstract
The utility model provides a die cavity for producing the magnetron magnet, belongs to the manufacturing molding die field, and in particular relates to the die cavity for producing annular alnico of microwave oven magnetron. The die cavity consists of a non-magnetic steel basal body die cavity skin, a non-magnetic abrasion resistant rigid alloy steel inner circle molding layer, and a magnetism conducting steel layer. The magnetism conducting steel layer (3) is tightly embedded in a proper-depth and a proper-thickness interface between the non-magnetic steel basal body die cavity skin (1) and the non-magnetic abrasion resistant rigid alloy steel inner circle molding layer (2). The utility model has brief and scientific structure, and excellent stability. Annular alnico products molded by the die cavity with the structure of the utility model can ensure the intensity requirement of the central magnetic field without reducing the volume of the product, and can meet the high-performance index level when the volume of the entire machine product is required to be smaller.
Description
Technical field
The utility model is used to produce the mold cavity of magnetron magnetite, belongs to manufacturing industry mould field, particularly produces the mold cavity of magnetron magnetite.
Background technology
The current mould that is used to produce the employed magnetite of magnetron, its die cavity position all adopts non-magnet_conductible material to make, the die cavity matrix is a nonmagnetic steel, and for prolonging the useful life of mould, the molded surface of circular hole is inlaid with wear-resisting non-magnesium hard alloy layer in this die cavity matrix.With the magnetite central magnetic field insufficient strength height that this kind mold cavity is produced, properties of product are undesirable.Along with expanding economy, market day by day strengthens the cry of product miniaturization, it is small and exquisite to press for volume, the good product that has excellent magnetic characteristics, if rely on the mould die cavity of existing structure to make the magnetite that small-sized magnetron uses, the specified heating power of the magnetron that it is produced will inevitably be less than assurance.The performance index of the specified heating power of the magnetite product of using in order to ensure the miniaturization magnetron must development of new magnetite mould cavity structure, to satisfy fast-developing market demand.
The utility model content
The purpose of this utility model provides a kind of mold cavity that is used to produce the magnetron magnetite, has specified heating power to guarantee to adopt this mold cavity to be produced the magnetite that small-sized magnetron uses, and satisfies the quality requirement of the various main computer boxes that adopt magnetron.
The purpose of this utility model is achieved by the following technical solution:
Originally be used to produce the mold cavity of magnetron magnetite, by nonmagnetic steel die cavity matrix skin, circle shape layer and magnetic conduction steel layer are formed in the no magnetic wearable hard alloy steel, and magnetic conduction steel layer 3 closely is embedded in nonmagnetic steel die cavity matrix outer 1 and does not have between the interface of circle shape layer 2 in the magnetic wearable hard alloy steel.Described magnetic conduction steel layer 3 closely be embedded in nonmagnetic steel die cavity matrix outer 1 and do not have the appropriate depth of circle shape layer 2 in the magnetic wearable hard alloy steel and the local interface of thickness between.
Prior art is produced the mold cavity of magnetron magnetite, the circle shape layer is not magnetic conduction steel in steel matrix skin that adopts and the wearable hard alloy steel, cause and adopt the central magnetic field intensity of the magnetite that this mold cavity produces not reach requirement, the utility model is by outer at above-mentioned nonmagnetic steel matrix and do not have in the magnetic wearable hard alloy steel and inlay magnetic conduction steel layer between the circle shape layer interface, appropriateness has been introduced magnetic layer, improve the magnetic field orientating of mold cavity from structure, therefore, improve the central magnetic field intensity of the magnetron magnetite product of being produced, satisfied the requirement of magnetron heating power.
Simple for structure, the science of the utility model, stability is good, adopt the magnetite product of the utility model structure mold mold cavity forming, can reduce to guarantee its central magnetic field intensity under the condition of small product size, thereby satisfy the high performance index requirement of machine product volume when compact.

Embodiment
How now further specify the utility model in conjunction with the accompanying drawings operates:
Add cost mold cavity product by the product specification requirement, and according to the utility model by nonmagnetic steel die cavity matrix outer 1 with there is not the structure of closely inlaying magnetic conduction steel layer 3 between circle shape layer 2 interfaces in the magnetic wearable hard alloy steel, press each parts of dimensioned of processing technology regulation respectively: processing nonmagnetic steel die cavity matrix outer 1 and interior circular hole, ring-shaped step is processed at the excircle appropriate depth place of circle shape layer 2 in no magnetic wearable hard alloy steel, by with no magnetic wearable hard alloy steel in justify the adaptive dimensioned magnetic conduction steel layer 3 of excircle ring-shaped step of shape layer 2.Then, adopt heat expansion technology, be enclosed within the excircle ring-shaped step of justifying shape layer 2 in the no magnetic wearable hard alloy steel after magnetic conduction steel layer 3 cover added thermal expansion, both closely rabbet after treating shrinkage, in like manner, with outer 1 heating of nonmagnetic steel die cavity matrix, there is tight interlocking the interior round shape layer 2 of no magnetic wearable hard alloy steel of magnetic conduction steel layer 3 to pack in the interior circular hole of nonmagnetic steel die cavity matrix skin 1, promptly obtain the utility model mold cavity after the cooling.In mould that this mold cavity is packed into,
Do not give unnecessary details process for machining herein.
The utility model mold cavity product is not limited by specification.
