Embodiment 1

[0034] Such as Figure 1-3 shown.

[0035] A tablet pressing mold, which is mainly composed of a molding head 1, a mold barrel 2, a mold core 3, a positioning pin 4, a mold base 5, an adjusting screw 6, a connecting screw 7, a slider 8 and a mold core base 9, such as figure 1 As shown, the mold barrel 2 is connected with the mold base 5 through the connecting screw 7, as figure 2 As shown, the mold core 3 and the mold core base 9 are installed in the guide hole in the mold cylinder 2, the slider 8 is movably fitted in the mold base 5, its upper flat end is offset against the mold core base 9, and the lower part of the slider 8 The slope at the inclined end is offset against the end of the adjusting screw 6 , which is screwed in the mold base 5 , and the axis of the adjusting screw 6 is perpendicular to the axis of the slider 8 . The locating pin 4 that controls the rising height of the mold core base 9 is installed on the mold barrel 2, and a boss is provided in the mountin...

Embodiment 2

[0040] Such as Figure 5 shown.

[0041] A molding method for powder compression, which comprises the following steps:

[0042] First, adjust the tableting die (such as figure 1 As shown), the adjusting screw 7 on the core base 9 moves upward until the upper surface of the core 3 installed on the core base 9 reaches the scale line corresponding to the height of the required initial powder loading; in specific implementation, in order to control the mold The height of the rise of the core base 9 can be installed on the mold barrel 2 with a positioning scale 4, and the axes of the positioning pin 4 and the adjusting screw 6 are all perpendicular to the axis line of the slider;

[0043] Secondly, the powder is packed in the mold cylinder 2, so that the upper surface of the powder exceeds the upper surface of the mold cylinder 2;

[0044] The third, scrape off the powder beyond the upper surface of the mold barrel 2 with a scribe until the upper surface of the powder is flush w...

Abstract

The invention discloses a molding method for powder tablets and a device thereof. The device is characterized by mainly comprising a molding head (1), a die barrel (2), a die core (3), a die base (5), an adjusting screw (6), a connecting screw (7), a slide block (8) and a die core base (9), wherein the die barrel (2) is connected with the die base (5) through the connecting screw (7); the die core (3) and the die core base (9) are arranged in a guide hole in the die barrel (2); the slide block (8) is movably sleeved in the die base (5); the upper flat end of the slide block (8) is pressed against the die core base (9); the inclined surface of the downwardly-inclined end of the slide block (8) is pressed against the end part of the adjusting screw (6); the adjusting screw (6) is screwed in the die base (5); and the axial lead of the adjusting screw (6) is vertical to the axial lead of the slide block (8). The device is easy and convenient to operate, height consistence and uniform particle density distribution of initial powder can be realized rapidly, and powder tablets of different heights can be prepared as required.

Description

technical field [0001] The present invention relates to a powder tableting technology, in particular to a powder tableting molding method and device thereof with controllable initial powder height and uniform distribution of powder particle density, in particular to a powder tableting molding method and its device. Background technique [0002] As we all know, in the manufacturing industry, the mold is the most common device, especially in the powder tableting experiment, the tableting mold is an indispensable tool. At present, there is little difference in the structure of the traditional infrared tablet pressing mold, which mainly includes four parts: the forming head, the mold cylinder, the mold core and the base, so the operation is simple and convenient. However, the traditional infrared tableting mold cannot quickly and accurately ensure that the initial height of the powder loaded each time is the same, that is, the repeatability is poor, and when the powder is loade...
