Description

Combined powder molding die

The utility model relates to a powder molding die.

The existing powder forming mold is formed on a piece of hard material, and a long strip-shaped through groove is cut out by a wire electric discharge machine as a female mold, and then combined with a male mold of a hard material. The female mold is more difficult to process, especially the polishing of the inner surface is difficult to process. In addition, when samples are pressed with such a mold, some samples are easily broken or surface cracked when demoulding, resulting in waste or defective products.

The purpose of this utility model is to provide a combined powder forming die with simple structure, convenient use and high yield in order to overcome the disadvantages of difficult processing of existing powder forming dies.

Below in conjunction with accompanying drawing, the utility model is described in detail.

The female mold front plate (10) and the female mold rear plate (13) of the utility model are two congruent cuboids, and the left and right ends of the two plates are symmetrically provided with four positioning pin holes (4), (19), (9), (11) and four fastening through holes (5), (18), (8), (15), the left clamping plate of female mold (17) and the right clamping plate of female mold (12) are also two congruent cuboid, the left clamping plate (17) of the female mold has positioning pin holes (4), (19) and fastening through holes (5), (18); the female mold right clamping plate (12) has positioning pin holes ( 9), (11) and fastening through hole (8), (15); One end of locating pin (3) has screw thread, puts and starts pin washer (2) and can cooperate with pin nut (1).

The structure of the present utility model is: between the female mold front plate (10) and the female mold rear plate (13), there are female mold left and right splints (17), (12), between the female mold front plate (10) and the female mold rear plate (13). On the female mold rear plate (13) and the female mold left clamping plate (17), have positioning pin holes (4), (19) and fastening through holes (5), (18), on the female mold front plate (10) And on the female mold rear plate (13) and the female mold right clamping plate (12), have positioning pin holes (9), (11) and fastening through holes (8), (15); positioning pins (3) pass through Locating pin holes (4), (19), (9), (11), fastening screw rod (7) pass through fastening through holes (5), (18), (8), (15); lower male die (6) be placed on the lower part between the front and rear plates (10), (13) and the left and right splints (17), (12) of the female mold, the upper male mold (16) is put into after filling; the front plate of the female mold (10 ) and the female mold rear plate (13) are two congruent cuboids; said female mold left splint (17) and female mold right splint (12) are also two congruent cuboids; one end of the positioning pin (3) has thread, put the lock washer (2) to cooperate with the lock nut (1).

The front plate (10) of the female mold is at the front, the rear plate (13) of the female mold is behind, the left clamping plate (17) of the female mold is at the left end of the front and rear plates (10), (13) of the female mold, and the right clamping plate (12) of the female mold is at the The right end of the front and rear plates (10), (13) of the female mold, the two splints are clamped in front of the female mold, between the rear plates (10), (13), positioned by four positioning pins (3), fastened by four Screw rod (7) and four fastening nuts (14) fasten, like this, by the rear surface of female mold front plate (10), the front surface of female mold rear plate (13), the right end of female mold left clamping plate (17) Face and the left end face of female mold right clamping plate (12) encircle a space through up and down, be the space of female mold work, following male mold (6) is at the lower part of female mold work space, and last male mold (16) is at the top.

During the work of the utility model, earlier the front plate (10) and the rear plate (13) of the female mold and the left and right splints (17) and (12) of the female mold are fixed with four fastening screws (7) and four positioning pins. Pin (3) is assembled into female mold, puts into lower male mold (6), fills in the powder material to be processed again, puts into upper male mold (16) again, finally the utility model is put into press and pressed. During demoulding, for materials that are not easy to break, you can top the male mold (16) earlier, and the processed block material is ejected from the lower male mold (6); Loosen four positioning pins (3), then loosen four screw rods (7), finally remove the pressure, and take out the processed block material.

The utility model has the advantages of:

1. The polishing process of the working space of the female mold is single-sided flat polishing, which is easy to process.

2. Changing the thickness of the male and female splints can produce samples of different thicknesses;

3. Demoulding can open the female mold under pressure, avoiding the rupture of the sample.

In a word, the utility model has the advantages of simple structure, easy processing and high yield, and is a combined powder molding die with ingenious conception.
