Description

Technical Field

[0001] This utility model relates to the field of hard capsule dispensing mold technology, specifically a hard capsule anti-scratch dispensing mold. Background Technology

[0002] Hard capsules are a commonly used drug carrier in the pharmaceutical and health product industries. Their production process includes core steps such as gel preparation, capsule molding, demolding and unloading, and quality inspection. The unloading mold is a key piece of equipment that connects capsule molding with subsequent processing. Its technological development has always revolved around three core demands: reducing capsule damage rate, improving production efficiency, and adapting to diverse needs.

[0003] For example, the authorization announcement number "CN216225680U" is named a mold cleaning device for hard capsule production. The setting of the traction spring makes the brush plate have an extension effect, which allows the brush plate to clean the grooves on the surface of the lower mold plate well. The existing hard capsule processing discharge mold is a necessary piece of equipment. The traditional hard capsule discharge mold is a round hole. Therefore, when the cylindrical capsule is discharged, it is in surface contact with the mold hole. The large contact area makes it easy to scrape the outer wall of the capsule and cause wear on the capsule surface. If there are tiny burrs on the inner wall of the mold hole or slight protrusions on the outer wall of the capsule, the surface contact will cause the scraping force to be concentrated on the contact area, which can easily lead to deformation and cracking of the capsule shell. Utility Model Content

[0004] The purpose of this invention is to solve the problem that existing hard capsule dispensing molds have a large contact area between the cylindrical capsule and the mold hole during dispensing, which easily scratches the outer wall of the capsule and causes wear on the capsule surface. Therefore, this invention proposes a scratch-resistant hard capsule dispensing mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution: Design a hard capsule anti-scratch discharge mold, including a mold body, a capsule forming area and positioning holes. Multiple positioning holes are fixedly opened on both sides of the interior of the mold body. The capsule forming area is fixedly installed inside the mold body. Multiple capsule bodies are movably connected to the inner side of the capsule forming area. The outer side of the capsule body is provided with a hard capsule anti-scratch structure. The inner side of the mold forming area is provided with a discharge mold hole plate replacement structure.

[0006] This design features positioning holes drilled on both sides of the mold body, which guides the mold body used for hard capsule ejection and forming to be placed under the equipment for hard capsule processing, facilitating positioning. The capsule forming area can be distinguished from the capsule body by using a different color, making it easy for staff to quickly determine the location of the capsule ejection.

[0007] Preferably, the hard capsule anti-scratch structure includes polygonal holes and fitting cavities. The fitting cavity is slidably connected to the outside of the capsule body. The polygonal holes are fixedly opened on the outside of the fitting cavity, and the inner walls of the plurality of polygonal holes are fixedly connected with anti-friction coatings.

[0008] This design ensures that when the capsule is ejected, its outer wall only makes line contact with the edges of the polygonal die hole. The reduced contact area directly leads to a decrease in the friction between the capsule and the die hole, reducing discharge resistance and minimizing drag damage to the capsule during ejection. At the same time, the line contact concentrates stress on the edges rather than on a large area. Even if there are minor defects on the inner wall of the die hole, they will only form local line contact with the capsule surface, making it less likely to cause large-area scratches or cracks.

[0009] Preferably, a capsule cap is movably connected to the top of the capsule body, and the outer wall of the capsule cap is slidably connected to the inner side of the polygonal hole.

[0010] In this configuration, the capsule body has a diameter of 7.34 mm, while the capsule cap 4 has a diameter of 7.58 mm, so the capsule cap can be fitted onto the capsule body for assembly.

[0011] Preferably, the discharge mold perforated plate replacement structure includes a reserved groove and a replacement plate. The reserved groove is fixedly opened inside the capsule forming area. The replacement plate is movably connected to the inner side of the reserved groove. The outer wall of the replacement plate is fixedly connected to an interlocking protrusion. The inner wall of the reserved groove is fixedly connected to a splicing groove. An octagonal hole is fixedly opened on the inner side of the replacement plate.

[0012] This setup allows the shape and size of the pre-drilled hole to match the replacement plate made of aluminum alloy. The replacement plate, with its inner polygonal hole, can be inserted into the pre-drilled hole inside the capsule forming area. Then, the trapezoidal interlocking protrusions are inserted into the splicing groove with a mortise and tenon joint, locking the replacement plate and the pre-drilled hole in place. Alternatively, the fixed replacement plate can be pried out, and another replacement plate with an octagonal hole can be inserted into the pre-drilled groove in the same way. This allows for different shapes of the discharge hole in the hard capsule discharge mold, making it more versatile.

[0013] Preferably, the sidewalls of the plurality of engagement protrusions are slidably connected to the inner side of the splicing groove.

[0014] In this configuration, the trapezoidal interlocking protrusions are inserted into the splicing groove with a mortise and tenon joint.

[0015] Preferably, a polygonal hole is fixedly opened on the inner side of the other replacement plate.

[0016] This setting allows for switching between polygonal and octagonal holes inside the hard capsule mold by changing the plate. The present invention provides a scratch-resistant ejection mold for hard capsules, which has the following advantages: when the capsule is ejected, its outer wall only forms line contact with the edge of the polygonal mold hole. The reduced contact area directly leads to a decrease in the friction between the capsule and the mold hole, reducing ejection resistance and minimizing drag damage to the capsule during ejection. At the same time, the line contact concentrates stress on the edge rather than on a large area. Even if there are minor defects on the inner wall of the mold hole, they will only form local line contact with the capsule surface, making it less likely to cause large-area scratches or cracks. In particular, it protects the locking part between the capsule cap and the capsule body, preventing scratches from affecting the sealing of subsequent drug packaging. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings: Example: Please refer to Figure 1-6 In this embodiment, a hard capsule anti-scratch dispensing mold includes a mold body 1, a capsule forming area 2, and positioning holes 3. The positioning holes 3 are drilled on both sides of the mold body 1, which can guide the mold body 1 used for hard capsule dispensing and forming to be placed under the equipment for hard capsule processing, which is convenient for positioning. Multiple positioning holes 3 are fixedly opened on both sides of the interior of the mold body 1. The capsule forming area 2 is fixedly installed inside the mold body 1, and the capsule forming area 2 can be distinguished from the capsule body 1 by different colors, which makes it convenient for the staff to quickly determine the position of capsule dispensing. Multiple capsule bodies 5 are movably connected to the inner side of the capsule forming area 2. The outer side of the capsule body 5 is provided with a hard capsule anti-scratch structure 7. The inner side of the mold forming area 2 is provided with a dispensing mold hole plate replacement structure 6.

[0020] The hard capsule anti-scratch structure 7 includes a polygonal hole 71 and a fitting cavity 72. The fitting cavity 72 is slidably connected to the outside of the capsule body 5. The polygonal hole 71 is designed as a regular hexagon. The polygonal shape on the inner side of the polygonal hole 71 is in line contact with the capsule, thereby reducing the contact area and thus reducing scratching and friction on the capsule. When the capsule is ejected, its outer wall only forms line contact with the edge of the polygonal die hole. The reduced contact area directly leads to a decrease in the friction between the capsule and the die hole, reducing discharge resistance and reducing dragging damage to the capsule during ejection. At the same time, the line contact makes... Stress is concentrated on the edges rather than on a large area. Even if there are minor defects on the inner wall of the mold hole, they will only form local line contact with the capsule surface, making it less likely to cause large-area scratches or cracks. In particular, it protects the locking part between the capsule cap and the capsule body, and avoids affecting the sealing of subsequent drug packaging due to scratches. A polygonal hole 71 is fixedly opened on the outer side of the bonding cavity 72. An anti-friction coating 73 is fixedly connected to the inner wall of multiple polygonal holes 71. The anti-friction coating 73 is a polytetrafluoroethylene coating sprayed on the edges and inner wall surface of the polygonal mold hole, which further reduces the friction between the capsule and the mold hole.

[0021] Capsule cap 4 is movably connected to the top of capsule body 5. The diameter of capsule body 5 is 7.34mm, while the diameter of capsule cap 4 is 7.58mm. Therefore, capsule cap 4 can be fitted onto capsule body 5 to achieve assembly. The outer wall of capsule cap 4 is slidably connected to the inner side of polygonal hole 71.

[0022] The material discharge mold perforated plate replacement structure 6 includes a pre-reserved slot 61 and a replacement plate 62. The pre-reserved slot 61 is fixedly opened inside the capsule forming area 2. The shape and size of the pre-reserved hole 61 match the aluminum alloy replacement plate 62. The replacement plate 62 can carry the inner polygonal hole 71 and be embedded into the pre-reserved hole 61 inside the capsule forming area 2. Subsequently, the trapezoidal interlocking protrusion 64 will be inserted into the splicing groove 63 with the cut trapezoidal groove using a tenon and mortise connection method, thus locking and fixing the replacement plate 62 and the pre-reserved hole 61. Alternatively, the fixed replacement plate 62 can be pried out by force, and then... Another replacement plate 62 with an octagonal hole 65 is inserted into the pre-reserved groove 61 in the same way. This allows for different shapes of the discharge hole of the hard capsule discharge mold, making it more versatile. The replacement plate 62 is movably connected to the inner side of the pre-reserved groove 61. The outer wall of the replacement plate 62 is fixedly connected to the interlocking protrusions 64. The inner wall of the pre-reserved groove 61 is fixedly connected to the splicing groove 63. The inner side of the replacement plate 62 is fixedly provided with an octagonal hole 65. The side walls of the multiple interlocking protrusions 64 are slidably connected to the inner side of the splicing groove 63. The inner side of another replacement plate 62 is fixedly provided with a polygonal hole 71.

[0023] Working principle: The hard capsule anti-scratch discharge mold reduces scratch damage and friction by changing the shape of the mold hole in the traditional mold and optimizing the contact method when the capsule is discharged. Positioning holes 3 are drilled on both sides of the mold body 1, which can guide the mold body 1 used for hard capsule ejection and forming to be placed under the equipment for hard capsule processing, making it convenient for positioning. The capsule forming area 2 can be distinguished from the capsule body 1 by different colors, making it convenient for staff to quickly determine the position of capsule ejection. The polygonal hole 71 is designed as a regular hexagon. The polygonal shape on the inner side of the polygonal hole 71 is in line contact with the capsule, thereby reducing the contact area and thus reducing the scratching and friction on the capsule. When the capsule is ejected, its outer wall only forms line contact with the edge of the polygonal die hole. The reduction in contact area directly leads to a decrease in the friction between the capsule and the die hole, reducing the discharge resistance and reducing the dragging damage of the capsule during the ejection process. At the same time, the line contact causes the stress to concentrate on the edge rather than a large area of ​​contact. Even if there are minor defects on the inner wall of the die hole, they will only form a local line contact with the capsule surface, making it less likely to cause large-area scratching or cracking. In particular, it protects the locking part between the capsule cap and the capsule body, and avoids the impact of scratching on the sealing of subsequent drug packaging. The anti-friction coating 73 is a polytetrafluoroethylene coating sprayed on the edge and inner wall surface of the polygonal die hole to further reduce the friction between the capsule and the die hole. The capsule body 5 has a diameter of 7.34 mm, while the capsule cap 4 has a diameter of 7.58 mm. Therefore, the capsule cap 4 can be fitted onto the capsule body 5 to achieve assembly. The shape and size of the reserved hole 61 match the aluminum alloy replacement plate 62. The replacement plate 62 can carry the polygonal hole 71 on the inner side and be inserted into the reserved hole 61 on the inner side of the capsule forming area 2. Then, the trapezoidal interlocking protrusion 64 will be inserted into the splicing groove 63 with the trapezoidal groove through the tenon and mortise connection, so that the replacement plate 62 and the reserved hole 61 are locked and fixed. Alternatively, the fixed replacement plate 62 can be pried out by force, and then another replacement plate 62 with the octagonal hole 65 can be selected and inserted into the reserved groove 61 in the same way. This can realize the change of different shapes of the discharge hole of the hard capsule discharge mold, making it more versatile.
