Fig. 2 is the portion's partial enlarged drawing of carving characters of die cavity in the mould shown in Figure 1.

Fig. 3 is another die cavity portion's partial enlarged drawing of carving characters.

Fig. 4 is the another die cavity portion's partial enlarged drawing of carving characters.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Figure 1 shows that the cross sectional representation of a rubber seal ring mould, among the figure, patrix 1, upper mold core 2, middle mould 3, counterdie 4 and counterdie 5 die cavitys 6 that formed the sealing ring mould of inserting.Be the die cavity portion 7 of carving characters on the inwall of the die cavity 6 of patrix 1 correspondence, be provided with the mark that the expression date increases progressively at the portion of carving characters 7 places.Make in the process of sealing ring at injection rubber in die cavity 6, die cavity carve characters date at portion 7 places increase progressively mark with regard to mint-mark on the sealing ring planar annular.Increase progressively mark by the date of mint-mark on product, can make things convenient for manufacturer and User Recognition to go out the date of manufacture of product.

Figure 2 shows that the carve characters partial enlarged drawing of portion 7 of die cavity among Fig. 1, in the portion of carving characters 7, be provided with the donut 7-1 that forms by two different circles of diameter, date increases progressively in the zone that mark is arranged on annulus 7-1, wherein, time indentation 7-14 is arranged on the annulus inner headed face 7-12, and the concave point 7-13 in expression month is arranged on the ring belt 7-11.With engraving machine donut 7-1 is carved at the portion of carving characters 7 places, then ring belt 7-11 evenly is divided into four sections, at least one section ring belt 7-11, go out 1,2 or 3 concave point 7-13 again, represent month with the number of concave point 7-13 with perforating press.Carve digital indentation 7-14 with engraving machine at annulus inner headed face 7-12 place again, be used for the expression of years.The numeral indentation adds the concave point number, can intactly express the productive year and the month of product.Because digital indentation 7-14 is " 06 ", there are two concave point 7-13 in the portion of carving characters as shown in Figure 2 in the circular ring marks, then the representative of the mark of this portion of carving characters is in February, 2006.

Because adopt the less concave point 7-13 of area to represent month, mark is simple, clear, convenient, and the shared area of whole mark is less, is particularly suitable on the less die cavity of area the date being carried out mark.

If month increases, the number that only needs to increase concave point 7-13 on ring belt 7-11 gets final product, and does not need the mark of floating last January, enhances productivity, and avoids the unnecessary damage of mould.

Die cavity shown in Figure 3 is carved characters in portion's partial enlarged drawing, owing to have 12 concave point 7-13 on the ring belt 7-11 of annulus 7-1, the digital indentation 7-14 at annulus inner headed face 7-12 place is " 06 ", so the date that this mark is represented is in December, 2006.

Fig. 4 has expressed time carve characters partial enlarged drawing of portion of die cavity when increasing, promptly with the increase in the method representation time that increases the annulus number.If the time that annulus inner headed face numeral indentation is represented is mistake, when forwarding next year to, only need increase the annulus 7-2 that an inside is provided with corresponding time indentation again on original annulus 7-1 next door, new 1 year month is still represented by the number of concave point on the endless belt.According to the concave point number on the endless belt in maximum time numeral indentation and the place annulus thereof, just can identify the date of manufacture of product, also can judge the service time of mould simultaneously.Date by the portion of carving characters shown in Figure 4 place increases progressively mark as can be known, and the date of manufacture of product is in May, 2007, and mould used at most 1 year 05 months.

In the actual use, can be according to the concrete structure of die cavity in the mould portion position of determining to carve characters, can also be according to the service life of mould, determine the annulus number that may need, thereby determine the outside diameter of the circular ring marks that is provided with in the portion of carving characters.

The digital indentation and the concave point mark on expression date are arranged in the circle ring area in the foregoing description, but are not limited to circle ring area, also date stamp can be arranged on other shapes, in the zones such as annular as " returning " type, two oval formation.

Certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example, and variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
