DETAILED DESCRIPTION

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Reference Figure 1 The utility model provides a medicine charging mold which is easy to disassemble and clean, including a base 1, an outer cylinder 2, an inner core 4, a feed hopper 3 and a connecting bolt 5. The base 1 serves as a basic support member of the entire mold, on which the outer cylinder 2 and the inner core 4 are fixedly mounted. The feed hopper 3 is mounted on the upper end of the outer cylinder 2 and is used to introduce the medicine material to be formed. A connecting mechanism 6 is provided on the outer cylinder 2, a bottom ear 101 is provided on the outer side of the base 1, and a top ear 301 is provided on the outer side of the feed hopper 3. The connecting bolt 5 passes through the bottom ear 101, the connecting mechanism 6 and the top ear 301 in sequence and is fixed by a nut, thereby forming the base 1, the outer cylinder 2 and the feed hopper 3 into a complete whole.

[0020] Reference Figure 2 , Figure 3 The outer cylinder 2 is composed of two semi-cylinders 201, each semi-cylinder 201 has a symmetrical structure, which is convenient for assembly and disassembly. The two semi-cylinders 201 are firmly spliced ​​through a connecting mechanism 6, so that the outer cylinder can be quickly disassembled for internal cleaning while maintaining good sealing performance.

[0021] The connecting mechanism 6 includes a connecting seat 601 fixedly mounted on the outer cylindrical surface of the semi-cylinder 201, and a through hole 602 is provided on the connecting seat 601 for passing the connecting bolt 5; a telescopic groove 603 connected to the through hole 602 is also provided on one side of the connecting seat 601, and a fixing seat 604 and a locking tongue 605 are provided inside the telescopic groove 603, and the fixing seat 604 and the locking tongue 605 are connected by a spring 606. When the two semi-cylinders 201 are not assembled, the locking tongue 605 can extend into the through hole 602 under the action of the spring force; after the two semi-cylinders 201 are assembled, the connecting bolt 5 passes through the through hole 602 to push the locking tongue 605 out of the through hole 602; at this time, the elastic force directions of the spring 606 of the connecting mechanism 6 on the two semi-cylinders 201 are opposite, and when acting on the bolt 5, the two semi-cylinders 201 are tightened to each other, thereby ensuring that the two semi-cylinders 201 are well assembled to avoid drug leakage.

[0022] A limit plate 202 is provided on the top of the semi-cylinder 201, and a positioning column 203 is provided on the limit plate 202. Correspondingly, a positioning plate 302 cooperating with the positioning column 203 is provided on the feed hopper 3, so that the outer cylinder 2 and the feed hopper 3 can be accurately aligned when connected to ensure the smooth progress of the charging process.

[0023] In addition, matching overlapping grooves 205 and overlapping strips 204 are respectively provided on both sides of the semi-cylinder 201 so that the two semi-cylinders 201 can fit tightly when combined to prevent the powder from leaking from the gap.

[0024] Reference Figure 4 The inner core 4 is composed of a conical head 402 and an inner tube 401. The setting of the conical head 402 is conducive to the smooth introduction and filling of the powder. The conical head 402 is installed at one end of the inner tube 401. The fixing bolt 7 passes through the base 1 and is threadedly connected with the conical head 402 to tighten and fix the inner core 4 on the base 1.

[0025] In order to facilitate the understanding of the present invention, the following Figure 1 - Figure 4 The working principle of this solution is described in detail:

[0026] The assembly steps are as follows:

[0027] 1. Pass the fixing bolt 7 of the inner core 4 through the base 1 and thread it into the conical head 402, tighten and fix the inner core 4 on the base 1;

[0028] 2. After the connecting bolt 5 passes through the bottom ear 101, the combination of the base 1 and the inner core 4 is placed vertically;

[0029] 3. Align and fit the overlapping strips 204 and overlapping grooves 205 of the two semi-cylinders 201 to preliminarily assemble the outer cylinder 2;

[0030] 4. Pass the connecting bolt 5 through the through hole 602 and install the outer cylinder 2 on the base 1;

[0031] 5. Install the feed hopper 3 above the outer tube 2 and tighten the nuts on the connecting bolts 5.

[0032] During the assembly and disassembly process, it is only necessary to tighten and disassemble the connecting bolts 5 and the fixing bolts 7, which simplifies the operation compared with the existing charging mold. The outer cylinder 2 composed of two semi-cylinders 201 is not only easy to demould, but the split design is also conducive to cleaning the inside.
