Abstract
The utility model discloses the dry-pressing formed die of a kind of electronic ceramics, comprise: die body (1), described die body (1) has die cavity (11), edge, the chamber of described die cavity (11) is provided with multiple inclined groove (101), described inclined groove (101) is deep-slotted chip breaker or square groove, and the gradient of described inclined groove (101) bottom land is 45 °-75 °.By offering side's examination of inclined groove, some powders are just run out of when just starting punching press in the place making product density large, thus can improve the flowing of powder, change the density of product, thus reach guarantee product size precision, guarantee product quality.
Description
Technical field
The utility model relates to electronic ceramics Product processing equipment technical field, particularly the dry-pressing formed 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.
Existing dry-pressing formed die as shown in Figure 1, meet on occasion some length and width sizes differ to product, if it is bad to fit the mobility of encountering powder, or powder granularity is uneven, or die wall is not very smooth, cause in punching course product density differ to, when sintering, the shrinkage ratio of all directions differs greatly, make finished product produce larger distortion, have impact on the precision of finished product, also have impact on the serviceability of product simultaneously.
Utility model content
In order to solve the problem of prior art, the utility model embodiment provides the dry-pressing formed die of a kind of electronic ceramics.Described technical scheme is as follows:
Provide the dry-pressing formed die of a kind of electronic ceramics, comprise: die body, described die body has die cavity, and edge, the chamber of described die cavity is provided with multiple inclined groove, described inclined groove is deep-slotted chip breaker or square groove, and the gradient of described inclined groove bottom land is 45 °-75 °.
Further, described inclined groove is arranged on the relative chamber, both sides of described die cavity along upper, chamber, every side is equal along the quantity of upper described inclined groove, or chamber, side is along upper described inclined groove number ratio opposite side chamber along many one upper of described inclined groove quantity.
The beneficial effect that the technical scheme that the utility model embodiment provides is brought is:
By offering side's examination of inclined groove, some powders are just run out of when just starting punching press in the place making product density large, thus can improve the flowing of powder, change the density of product, thus reach guarantee product size precision, guarantee product quality.
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 structural representation of prior art die.
Fig. 2 is the cavity 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 die of a kind of electronic ceramics, incorporated by reference to reference to figure 2, the dry-pressing formed die of this electronic ceramics comprises: die body 1, die body 1 has die cavity 11, edge, the chamber of die cavity 11 is provided with multiple inclined groove 101, inclined groove 101 is deep-slotted chip breaker or square groove, and the gradient of inclined groove 101 bottom land is 45 °-75 °.
Preferably, inclined groove 101 is arranged on the relative chamber, both sides of die cavity 11 along upper, and chamber, every side is equal along the quantity of upper inclined groove 101, or chamber, side is along upper inclined groove 101 number ratio opposite side chamber along many one upper of inclined groove 101 quantity.
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.
