Description

Technical Field

[0001] This utility model relates to the field of fireworks manufacturing equipment technology, specifically to a cylinder-type material pressing mold. Background Technology

[0002] In the process of fireworks production, pressing molds are required. Such equipment is widely used on production lines that need to position and compact bulk particles or powders in a porous array. The filling and compaction actions are usually completed by reciprocating motion between the upper and lower molds.

[0003] In existing drug cartridge pressing devices, the common structure is to arrange several hollow cylindrical drug cartridge units on a working support, and use a forming mold that can move up and down to drive multiple push rods or needles to enter each drug cartridge at the same time to compact the powder inside. After the push rods are withdrawn from the drug cartridge, their outer walls are often covered with powder. As the mold is raised, these adhering substances are easy to fall off the push rods and fall into the support or adjacent drug cartridges, causing cross-contamination, increasing the cleaning burden and affecting the consistency of the finished product.

[0004] Furthermore, if the push rod is pressed again without being wiped clean, the adhering drug dust on its exterior will increase the friction between it and the drug dust, which may pose a certain safety hazard in some high-frequency and high-intensity processing environments.

[0005] Some existing solutions rely on complex air blowing, vacuuming, or multi-part cleaning mechanisms, but these solutions increase structural complexity and maintenance costs, and are not convenient to retrofit and promote on existing equipment.

[0006] Therefore, we propose an in-cylinder material pressing mold to solve the problems mentioned above. Utility Model Content

[0007] Technical problems to be solved

[0008] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a cylinder-type medicine pressing mold, which can solve the problem of filler falling off and overflowing during the compaction / retraction process of the filler in the existing technology.

[0009] Technical solution

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] This utility model provides a cylinder-type medicine pressing mold, including a platform and an upper mold disposed above the platform and capable of reciprocating in the vertical direction. The lower end of the upper mold is provided with an array of pins that correspond one-to-one with the medicine column groups on the platform and are used to compact the medicine powder in the medicine column groups. A partition is fixedly disposed between the upper mold and the platform. The partition has a plurality of through holes at the positions corresponding to the pin arrays for the pin arrays to pass through, and the pin arrays are clearance-fitted with the through holes.

[0012] Furthermore, the pharmacopoeia on the platform is provided in two groups.

[0013] Furthermore, the drug grains in the drug grain assembly are arranged in a hexagonal pattern on a two-dimensional plane.

[0014] Furthermore, a positioning plate is fixed to the lower end of the partition plate, and the positioning plate has a hexagonal groove that corresponds to the hexagonal outer edge of the drug column assembly and is used to position and engage the drug column assembly.

[0015] Furthermore, a spring is provided between the partition and the upper mold.

[0016] Furthermore, the partition is made of metal and is fixed to the upper part of the platform with fasteners.

[0017] Furthermore, the fastener is a screw.

[0018] Furthermore, the inner edge of the through hole is machined with a chamfer or rounded.

[0019] Furthermore, the positioning plate is made of metal.

[0020] Furthermore, a wear-resistant bushing is removable inside the through hole.

[0021] Beneficial effects

[0022] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0023] This utility model fixes a partition plate between the upper mold and the platform and opens a through hole on the partition plate to match the pin, so that the pin and the through hole are in clearance fit. When the pin passes through the through hole, the edge of the through hole can wipe the outer wall of the pin to remove the adhering powder.

[0024] The baffle also serves as a guide reference for the pin to ensure concentricity with the propellant column, thereby improving compaction consistency and reducing pollution and cleaning workload caused by powder shedding. Compared with active cleaning methods such as air blowing or vacuuming, this solution achieves the dual functions of wiping and guiding with a simple rigid component, which is easy to modify on existing equipment and easy to inspect and maintain.

[0036] The present invention will be further described below with reference to the embodiments.

[0037] Example:

[0038] See attached document Figure 1-5 This solution proposes an in-cylinder material compression mold, as shown in the figure. The filling and compaction mold in this embodiment includes a platform 1 and an upper mold 2. The platform 1 is made of high-strength cast iron or steel plate welded together, and its surface is treated with anti-rust to ensure stability and corrosion resistance under long-term use.

[0039] Several vertically arranged slide rods 14 are fixed at the upper end of the platform 1. The upper mold 2 is fitted on the slide rods 14 and guided by them to achieve stable vertical reciprocating motion. The upper mold 2 is driven by a drive mechanism (such as a hydraulic cylinder, air cylinder or electric push rod, not shown in the figure) to complete the pressing and retraction actions.

[0040] A pin array 3 is provided at the lower center of the upper mold 2. The number of pin arrays 3 corresponds to the drug column group placed on the stage 1, and the number of pins 3a on each pin array 3 corresponds to the number of drug columns 8 in drug column group A and / or drug column group B. The pins 3a are used to compact the drug powder into individual drug columns 8 during the downward stroke. The diameter of the pins 3a is determined according to the inner diameter of the drug column 8, and is usually slightly smaller than the inner diameter of the drug column 8 to ensure smooth insertion and compaction of the drug powder. The arrangement of the pins 3a on the two-dimensional plane corresponds completely to the hexagonal arrangement of the drug columns 8 in the drug column group, ensuring that each pin 3a can be accurately aligned and enter the corresponding drug column 8.

[0041] The partition 4 is a rigid metal plate, preferably made of wear-resistant stainless steel. It is fixed to the upper part of the platform 1 by fasteners 12 (screws are used in this case). The partition 4 has several through holes 5 machined at the positions corresponding to the pin array 3. The through holes 5 and the pins 3a are in clearance fit. The clearance can be adjusted according to the outer diameter of the pins 3a (a smaller clearance can enhance the wiping effect, and a larger clearance is conducive to reliable passage) to ensure that the pins 3a can pass through smoothly and make wiping contact with the periphery of the through holes 5 during the passage process.

[0042] During assembly, two sets of pill groups 6 and 7 arranged in a hexagonal pattern are first positioned on the platform 1, so that the outer edge of the pill 8 fits into the hexagonal groove 10 of the positioning plate 9. Then, the upper mold 2 is hung on by the slide rod 14 and the upper mold 2 is ensured to descend smoothly. The initial position of the pin array 3 is that the pin 3a is embedded in the through hole 5.

[0043] When the upper mold 2 moves down and compresses the spring 11, the pin 3a passes through the hole 5 and enters the medicine column 8 to complete the compaction. At the moment of passing through, the edge of the hole 5 wipes the outer wall of the pin 3a, scraping off the adhering medicine powder.

[0044] When the upper mold 2 retracts, the pin 3a retracts and is re-embedded in the through hole 5, in the containment position of the partition 4, thereby effectively preventing powder from falling onto the stage 1 or the adjacent drug column 8 during the rising phase of the upper mold 2.

[0045] Optionally, a chamfer or rounded edge can be machined along the inner edge of the hole 5 to improve the scraping and wiping effect on the pin 3a and reduce local wear on the surface of the pin 3a.

[0046] The lower end of the partition 4 is rigidly connected to the positioning plate 9. The positioning plate 9 is fixed to the lower end of the partition 4 by welding or screws. The material is the same as that of the partition 4. The positioning plate 9 has a hexagonal groove 10 that corresponds to the outer edge of the pill assembly. This is to position the outer edge of the pill assembly, which is arranged in a hexagonal pattern, to a predetermined reference position. This ensures that the pin array 3 is concentric with each pill 8 when pressed down, and that the pill assembly can be quickly and accurately positioned when placed, avoiding displacement during the pressing process. The inner wall of the hexagonal groove 10 can be lined with wear-resistant rubber or plastic pads to reduce the impact on the outer wall of the pill 8.

[0047] A spring 11 is installed between the partition plate 4 and the upper mold 2. The function of the spring is to provide force buffer when the upper mold 2 moves downward and the pin 3a passes through the through hole 5, and to provide buffer when the upper mold 2 is pressed down, so as to avoid rigid collision between the pin 3a and the drug cartridge 8 and avoid excessive instantaneous impact. At the same time, when the upper mold 2 stops or retracts, it helps the pin 3a to return to the embedded state in the through hole 5, and the restoring force of the spring 11 helps the pin 3a to quickly retract into the through hole 5, reducing powder carrying.

[0048] When it is necessary to replace or maintain the partition 4, simply remove the fastener 12 to remove the partition 4 and the positioning plate 9, clean the residual powder in the through hole 5 and the hexagonal groove 10, and if the through hole 5 is severely worn, a replaceable wear-resistant bushing can be installed in the hole to extend the service life of the partition 4.

[0049] Optionally, to improve cleaning efficiency and ease of operation, a dust collection trough can be arranged below the partition 4 or at the corresponding position of the platform 1, or an external vacuum port can be reserved to connect a suction device to collect scraped dust when needed (this is known technology and is not shown in the figure).

[0050] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
