Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing device production, in particular to a medicine pressing mold for an aerosol generating agent. Background Art

[0002] Aerosol generating agent columns are usually formed by compressing aerosol generating agent powder. Aerosol generating agents of different dosages and sizes usually use different compression molds according to the depth of the compression mold. However, since the agent in the mold is not always evenly distributed during the compression process, the high-density part of the agent exerts a large pressure on the inner wall, and the low-density position exerts a small pressure. Therefore, during the compression of the aerosol generating agent column, the compression mold will be damaged. In addition, during the compression, the core mold will also damage the inner wall of the compression mold, and the compression mold needs to be replaced more frequently. Since the inside of the mold is required to have a very smooth inner surface and the mold is required to have a high strength, the existing mold is customized by machining, and the frequent replacement of the entire mold causes an increase in production costs. Utility Model Content

[0020] In the figure, there are an outer tube body 10 , a slot 11 , a threaded hole 12 , a tube joint 13 , a connecting portion 131 , a matching portion 132 , an inner tube body 20 , a gasket 30 , a positioning hole 31 , and a screw 40 . DETAILED DESCRIPTION

[0021] See also Figure 1-3A medicine pressing mold for an aerosol generating agent comprises an outer tube body 10 and an inner tube body 20, wherein the inner tube body 20 is inserted into the inner hole of the outer tube body 10, a slot 11 is axially arranged on the inner wall of the outer tube body 10, a gasket strip 30 is installed in the slot 11, and a plurality of threaded holes 12 are arranged on the tube wall of the outer tube body 10 along the slot 11. By designing the medicine pressing mold into an outer tube body 10 and an inner tube body 20 inserted into the inner hole of the outer tube body 10, the outer tube body 10 has a high strength requirement and a low roughness requirement, while the inner tube body 20 has a relatively low strength requirement and a higher roughness requirement. When the medicine pressing mold is worn, it is also convenient to replace the inner tube body, thereby saving production costs.

[0022] Specifically in use, the outer tube body 10 is customized by machine processing, and the inner tube body 20 is made of a stainless steel thin-walled tube. The thickness of the stainless steel thin-walled tube is about 1.5 mm. The inner wall of the stainless steel thin-walled tube is polished and ground. When in use, the stainless steel thin-walled tube is lightly tapped into the outer tube body 10 and fixed. When the inner tube body 20 is worn, only the stainless steel thin-walled tube needs to be replaced, thereby saving production costs.

[0023] However, after the stainless steel thin-walled tube is repeatedly squeezed in the outer tube body 10, the inner tube body 20 is deformed outward, making it difficult to remove the inner tube body 20 when replacing it. Therefore, a slot 11 is axially arranged on the inner wall of the outer tube body 10, and a pad 30 is installed in the slot 11. The pad 30 plays a role in padding the slot 11 to ensure that the inner hole of the outer tube body 10 is circular. A plurality of threaded holes 12 are arranged on the tube wall of the outer tube body 10 along the slot 11. In this way, when removing the inner tube body 20, the pad 30 is first taken out, and then see Figure 4 , 5 The screw 40 is screwed through the threaded hole 12, and the inner tube body 20 is squeezed and recessed by the screw 40, and then the inner tube body 20 can be easily knocked out.

[0024] Further, the outer tube body 10 is formed by connecting a plurality of tube segments 13, so that when the inner tube body 20 is disassembled, Figure 6 , the inner tube body 20 does not need to be knocked, but the tube sections 13 can be removed one by one, thereby separating the outer tube body 10 from the inner tube body 20 more simply.

[0025] Furthermore, in order to ensure the stability of adjacent tube segments during the drug column compression process, the opposite ends of the adjacent tube segments 13 are respectively provided with a connecting portion 131 and a matching portion 132, and the connecting portion 131 and the matching portion 132 cooperate with each other to position the adjacent tube segments 13 concentrically.

[0026] Specifically, the connecting portion 131 is a ring groove, and the matching portion 132 is a convex ring, or the connecting portion 131 is a plurality of circular holes, and the matching portion 132 is a circular boss.

[0027] See also Figure 2 , 3, one end or both ends of the cushion strip 30 are provided with a positioning hole 31. When taking out the cushion strip 30, a punch needle can be inserted into the positioning hole 31, and the cushion strip 30 can be taken out by knocking the punch needle.

[0028] The working process or principle of the utility model is as follows:

[0029] During installation, multiple pipe sections 13 are stacked to form the outer pipe body 10, the slots 11 on each pipe section 13 are aligned, the pads 30 are inserted into each slot 11, and then the inner pipe body 20 is lightly tapped into the outer pipe body 10 to be fixed. Of course, in order to prevent each pipe section 13 from falling off after installation, a set screw can also be screwed into the threaded hole 12.

[0030] When removing the inner tube body 20, first take out the cushion strip 30, then refer to Figure 4 , 5 , screw the screw 40 through the threaded hole 12, squeeze the inner tube 20 with the screw 40 and then screw out the screw 40, see Figure 6 , only the pipe sections 13 can be removed in sequence, so that the outer pipe body 10 and the inner pipe body 20 can be separated more simply. Thereby, a new inner pipe body 20 can be replaced, and the outer pipe body 10 can be recycled.
