Abstract
The utility model discloses the dry-pressing formed bed die of a kind of electronic ceramics, comprise: lower mould body (1), described lower mould body (1) has die wall (11) and die cavity (12), described die wall (11) offers row's powder aperture (13) that some and described die cavity (12) is connected, and the aperture of described row's powder aperture (13) is 0.35mm-1.0mm.By offering the row's powder aperture be connected with die cavity on die wall, namely on counterdie, core bar relevant position begins to rehearse powder aperture, the powder gone between core bar and core bar, between core bar and die by die assembly gap is run out of by row's powder aperture, make it be unlikely to stay inside mould, affect quality and the manufacturing schedule of product.
Description
Technical field
The utility model relates to electronic ceramics Product processing equipment technical field, particularly the dry-pressing formed bed die of a kind of electronic ceramics.
Background technology
The pottery of electricity, magnetic property can be utilized in the electronics industry, be called electronic ceramics.Electronic ceramics finally obtains the pottery with New function by the control of effects on surface, crystal boundary and dimensional structure.Can extensive use in the energy, household electrical appliance, automobile etc.
When powder granularity reaches requirement, generally can produce smoothly, powder could not stick on the core bar in counterdie with sliding right porcelain power production! If but powder granularity is bigger than normal, or during with 95 porcelain, the product of often production some, just has on core bar that powder sticks in counterdie, scratches product surface, increase the friction between dieparts.Thus mould will be removed at regular intervals and remove the normal production of powder ability, have impact on manufacturing schedule.
Utility model content
In order to solve the problem of prior art, the utility model embodiment provides the dry-pressing formed bed die of a kind of electronic ceramics.Described technical scheme is as follows:
Provide the dry-pressing formed bed die of a kind of electronic ceramics, comprising: lower mould body, described lower mould body has die wall and die cavity, and described die wall offers row's powder aperture that some and described die cavity is connected, and the aperture of described row's powder aperture is 0.35mm-1.0mm.
Further, described row's powder aperture is arranged on the relative two side of described die wall, the relative two side of described die wall is respectively arranged two or three described row's powder apertures.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By offering the row's powder aperture be connected with die cavity on die wall, namely on counterdie, core bar relevant position begins to rehearse powder aperture, the powder gone between core bar and core bar, between core bar and die by die assembly gap is run out of by row's powder aperture, make it be unlikely to stay inside mould, affect quality and the manufacturing schedule of product.
Accompanying drawing explanation
In order to be illustrated more clearly in the technical scheme in the utility model embodiment, below the accompanying drawing used required in describing embodiment is briefly described, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the lower die structure schematic diagram that the utility model embodiment provides.
Detailed description of the invention
For making the purpose of this utility model, technical scheme and advantage clearly, below in conjunction with accompanying drawing, the utility model embodiment is described in further detail.
Embodiment
Present embodiments provide the dry-pressing formed bed die of a kind of electronic ceramics, incorporated by reference to reference to figure 1, this bed die comprises: lower mould body 1, lower mould body 1 has die wall 11 and die cavity 12, die wall 11 offers some row's powder apertures 13 be connected with die cavity 12, and the aperture of row's powder aperture 13 is 0.35mm-1.0mm.
Preferably, row's powder aperture 13 is arranged on the relative two side of die wall 11, the relative two side of die wall 11 is respectively arranged two or three row's powder apertures 13.
The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
