Problems solved by technology

[0003] But at present, the cooperation between the top mold and the mold cavity is a tight fit, and the sample powder is easy to absorb water and adhere to the inner wall of the mold cavity, so that the top mold is in the process of film pressing and demoulding. The friction resistance between them is large, not only it is difficult to press the film and release the mold, but also it is easy to damage the formed sheet, which often leads to the failure of the tablet and repeated tablet operations

Abstract

The invention relates to a powder slice pressing forming die capable of being disassembled conveniently. The die comprises a base provided with a round boss, and a die frame connected with the base. The center of the die frame is coaxially provided with a first guide hole and a second guide hole which communicate with each other. A lifting seat making contact with the inner wall of the first guide hole slidably is installed in the first guide hole. A lower pressing head connected with the lifting seat is installed in the second guide hole. A lifting adjusting rod is connected to the bottom of the lifting seat, installed in a base guide hole and connected with an eccentric adjusting device. A matched upper pressing head is arranged above the lower pressing head. At least two lifting adjusting screws are arranged on the outer side of the second guide hole axially. According to the die, die disassembly and die release are convenient, powder extrusion core forming is convenient, and after the lower pressing head extends out of the guide holes, a formed slice can be taken out and put in a transmission detector to be subjected to transmission detection conveniently.

Description

technical field [0001] The invention belongs to the technical field of infrared detection, and in particular relates to a mold for forming a powder tablet which is convenient for mold unloading. Background technique [0002] The infrared tableting mold is used to press the test sample. The general mold includes a base and a mold cylinder arranged on the base. Placed between the lower end of the top mold and the lower tablet block. [0003] But at present, the cooperation between the top mold and the mold cavity is a tight fit, and the sample powder is easy to absorb water and adhere to the inner wall of the mold cavity, so that the top mold is in the process of film pressing and demoulding. The frictional resistance between them is large, which not only makes it difficult to press the film and release the mold, but also easily damages the formed sheet, which often leads to the failure of the tableting and repeated tableting operations. Contents of the invention [0004] ...
