Description

Technical Field

[0001] This utility model relates to the field of fireworks manufacturing equipment technology, specifically to a propellant column forming and 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 the prior art, the filling and compaction cycle is often accompanied by the adhesion and retention of filler on the contact surface, compaction part and its surroundings. Especially when the compaction part or pusher part retracts from the groove or hole, the powder or particles attached to its surface often fall off and fall into the forming surface or surrounding area, causing the workpiece or equipment surface to be contaminated, requiring additional cleaning, and may affect the stability of subsequent processes and product consistency.

[0004] Furthermore, the strong adhesion of this type of powder, if not cleaned in time, can lead to increased friction between the compactor or pusher and the powder during the next pressing process, posing a certain safety hazard.

[0005] To reduce this type of shedding and contamination, existing technologies have employed various methods, such as external blowing, vacuuming, surface coating, removable cleaning components, or sealing protection. However, these measures often increase equipment complexity, occupy additional space or maintenance resources, and under certain operating conditions, they are still difficult to completely solve the problem of shedding and scattering during the retreat phase.

[0006] Therefore, how to effectively suppress or control the shedding and overflow of filler during compaction / retraction without significantly increasing system complexity and maintenance burden, and how to facilitate compatibility and modification with existing mold systems, remains an urgent problem to be solved in this technical field.

[0007] Therefore, we propose a precipitate forming and pressing mold to solve the problems mentioned above. Utility Model Content

[0008] Technical problems to be solved

[0009] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a dummy charge forming and 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.

[0010] Technical solution

[0011] To achieve the above objectives, this utility model provides the following technical solution:

[0012] This utility model provides a pill forming and pressing mold, including a pressing panel, an upper mold, and a partition. The pressing panel has multiple hollow column slots for filling with pill powder. The lower end of the upper mold is provided with an array of pins corresponding to the hollow column slots. The partition is disposed between the pressing panel and the upper mold. During the reciprocating motion of the upper mold, the partition moves relative to the pin array, so that after the pins exit the hollow column slots, they come into contact with the partition and scrape off the pill powder adhering to the outer wall of the pins.

[0013] Furthermore, the multiple hollow column slots are arranged in a matrix.

[0014] Furthermore, the partition is movably installed at the lower end of the upper mold.

[0015] Furthermore, the partition is flexibly and movably mounted on the lower end of the upper mold.

[0016] Furthermore, the partition is fixed to the upper end of the panel to be pressed.

[0017] Furthermore, the partition plate is provided with a cleaning cavity that corresponds to and is connected through the pin array.

[0018] Furthermore, the cleaning cavity can be any one of a hole or a groove.

[0019] Furthermore, an elastic member is provided between the partition and the upper mold, so that the partition first contacts the panel to be pressed and undergoes elastic compression when the upper mold moves down, and then the pin passes through the cleaning cavity and enters the hollow column groove during the further downward movement.

[0020] Furthermore, the elastic member is a plurality of compression springs arranged in a matrix.

[0021] Furthermore, the partition is made of metal.

[0022] Beneficial effects

[0023] The technical solution provided by this utility model has the following advantages compared with the prior art:

[0024] This utility model, by setting an elastically movable partition between the lower end of the upper mold and the panel to be pressed, can complete the mechanical wiping and concentrated powder removal of the adhering material on the outer wall of the pin during the process of the upper mold moving down and retracting;

[0025] As the pin retracts into the cleaning chamber, the contact wiping of the cleaning chamber against the outer wall of the pin removes a large amount of adhering material, causing the wiped-off powder to naturally fall into the corresponding hollow column groove, thus preventing the powder from scattering on the panel surface or the surrounding environment.

[0026] By using mechanized wiping and cleaning processes, blockages, errors, or contamination caused by deposits on the pins are reduced, thereby minimizing downtime and manual intervention due to cleaning, and improving overall production efficiency and product consistency.

[0041] The present invention will be further described below with reference to the embodiments.

[0042] Example:

[0043] See attached document Figure 1-8 This solution proposes a drug cartridge forming and pressing mold, as shown in the figure. The filling and compaction mold of this embodiment includes a pressing panel 1, a hollow column groove 2, an upper mold 3, a pin array 4, a partition 5, a cleaning cavity 6, an elastic component 7, and a guide column 8.

[0044] The panel to be pressed 1 is a flat substrate with multiple hollow column grooves 2 arranged in a matrix on it. Each hollow column groove 2 is used to accommodate the filler to be pressed.

[0045] The upper mold 3 is located above the panel 1 to be pressed, and a pin array 4 is provided at its lower end. Each pin of the pin array 4 is used to enter the corresponding hollow column groove 2 to carry out the compaction action. The upper mold 3 can be driven by a cylinder or other drive structure to move back and forth up and down.

[0046] A partition 5 is provided between the lower end of the upper mold 3 and the panel 1 to be pressed. The partition 5 is elastically movable relative to the lower end face of the upper mold 3 to allow relative displacement during the reciprocating motion of the upper mold. The shape of the partition 5 matches the lower end of the upper mold 3 to ensure coaxial alignment within the stroke.

[0047] The partition 5 has a through cleaning chamber 6 corresponding to the pin array 4. The cleaning chamber 6 and the pin 4 are fitted together in a certain way. The cleaning chamber 6 can be any of the following: a hole, a groove (including a strip groove), or an opening that matches the shape of the pin (such as a conical hole, a polygonal hole, etc.). It can scrape the outer wall of the pin as the pin passes through, thus achieving a cleaning effect. In addition, the inner wall of the cleaning chamber is provided with a chamfer or rounded transition to further optimize the scraping effect. The inner wall of the cleaning chamber 6 is provided with a chamfer or rounded transition to facilitate a smooth wiping contact surface and reduce wear.

[0048] Specifically, a cleaning chamber 6 with a scraper or brush can be used, with an elastic scraper or brush bristles installed inside the cleaning chamber 6 to enhance the cleaning effect. Alternatively, a replaceable wear-resistant bushing (such as hard alloy) can be used inside the cleaning chamber 6, or an opening can be formed inside the cleaning chamber 6 with an elastic material (such as rubber or polyurethane) to scrape the pin 4 by elastic deformation.

[0049] Four elastic components 7 are arranged on the back or edge of the partition 5. In this embodiment, the elastic components 7 are compression springs, arranged in a matrix to achieve the overall elastic displacement of the partition 5. The panel to be pressed 1 is slidably engaged with the upper mold 3 through the guide post 8. The guide post 8 ensures that the panel to be pressed 1 is stably displaced in the vertical direction without significant tilting.

[0050] The partition plate 5 is preferably made of metal to improve wear resistance and service life. The upper mold 3, pin 4 and other structural components can also be made of conventional mold steel or other engineering metals, and the guide post 8 can be made of hard steel and used with a sliding sleeve to reduce wear.

[0051] The cleaning chamber 6 can be a circular through hole or adjusted according to the shape of the pin; a chamfer or rounded transition can be provided at the inner edge of the through hole to facilitate a smooth wiping contact surface.

[0052] In one filling and compaction cycle, the upper mold 3 moves from top to bottom. When it reaches a certain position, the partition 5 first contacts the panel 1 to be pressed (or approaches its upper surface). During this contact process, the elastic member 7 undergoes elastic compression. At this time, the partition 5 moves relative to the upper mold 3, completing the pre-contact positioning.

[0053] As the mold continues to descend, the pin array 4 moves further down with the upper mold 3, passing through the cleaning chamber 6 on the partition 5 and entering the corresponding hollow column groove 2 to compact the filler in the hollow column groove 2. After compaction is completed, the upper mold 3 begins to move upward.

[0054] During the retraction (ascent) process, the pin 4 first exits the hollow column groove 2 and finally retracts to the cleaning chamber 6 position of the partition 5. Due to the relative displacement and contact boundary between the partition 5 and the pin 4, the adhering material on the outer wall of the pin wiping contact with the inner edge of the cleaning chamber 6 when it retracts to the cleaning chamber 6. The adhering material that is wiped off falls back along the original direction of the hollow column groove 2 or falls back to its adjacent position under the action of gravity, thereby reducing the possibility of the filler scattering to the outside or contaminating the surface of the panel 1 to be pressed during the retraction of the upper mold.

[0055] The elastic component 7 plays a buffering and resetting role throughout the process. When the upper mold moves down, it allows the partition 5 to contact and be compressed first. When it retracts, the spring resets the partition to the initial position, ensuring the consistency of the cycle.

[0056] The partition 5 automatically cleans the deposits on the outer wall of the pin by relative displacement and contact wiping with the pin 4, reducing spillage pollution during the retraction phase.

[0057] In addition, since the wiping action and the pin retraction are completed simultaneously, the wiped material can fall back into the original hollow column groove 2 or its corresponding position, which facilitates the stability and cleaning maintenance of subsequent processes.

[0058] Furthermore, the elastic component 7 and the guide post 8 ensure the positioning and stroke repeatability of the partition 5, making the structure reliable and easy to achieve compatibility with existing mold systems.

[0059] In this embodiment, a preferred design is provided for the cooperation details between the cleaning cavity 6 and the pin 4. Specifically, the cleaning cavity 6 on the partition 5 is a through hole that communicates with the pin 4. The inner edge of the through hole can be slightly chamfered, and the chamfer radius of the inner edge matches the smoothness of the outer wall of the pin so as to achieve linear contact wiping when the pin passes through.

[0060] When the pin 4 retracts to the cleaning chamber 6, the contact between the pin and the inner edge of the through hole generates friction and wipes, causing the attached material to fall off the outer wall of the pin. The fit does not necessarily have to be a sealed fit; preferably, it is a fit within a certain range to balance the wiping effect with manufacturing / assembly tolerances.

[0061] To facilitate centralized return, the wiped-off material can be collected through the through-hole and returned to the adjacent hollow column trough 2 or the specially designed collection trough via the guide port or free fall (the collection trough is an optional structure and is not shown in the figure).

[0062] In this embodiment, there are four elastic members 7, which are arranged on the back or edge of the partition 5. The arrangement position corresponds to the force center and edge support requirements of the partition 5 to ensure that the partition 5 undergoes overall elastic compression displacement and uniform force distribution throughout the entire working stroke.

[0063] Specifically, the spring can be connected to the partition plate 5 and the upper mold 3 via a pressure plate or nested seat to ensure that the spring does not shift during the cycle.

[0064] The guide post 8 is fixed to the lower end of the upper mold 3 or the upper mold body, and cooperates with the panel to be pressed 1 through a sliding fit (sliding sleeve / bushing) to ensure that the axial travel of the panel to be pressed 1 is accurate and does not deflect. The guide post 8 also facilitates assembly and subsequent maintenance.

[0065] The partition 5 is a sliding fit structure that is fixed but can make elastic displacement under the action of the spring. That is, the panel itself and the upper mold are in a constant connection relationship during assembly, but can produce relative displacement under the action of the spring force.

[0066] In this embodiment, the partition 5 is designed to be fixedly fitted with the upper mold 3 (not easily disassembled) to reduce inconsistencies during assembly. However, during equipment maintenance or replacement, the partition or spring assembly can be replaced by disassembling the upper mold or guide column bushing.

[0067] The partition 5 is preferably made of a metal material to obtain good wear resistance and dimensional stability. Stainless steel or other engineering alloys can be used. When necessary, the surface of the partition can be moderately hardened or surface-finished to improve the wiping life.

[0068] The outer surface of the pin 4 preferably has a certain surface roughness or is surface treated to improve its wiping effect with the cleaning chamber 6 (the specific value or treatment method is not specifically limited here).

[0069] In this embodiment, the design of the partition 5 takes into account compatibility with the existing upper mold 3 and pin 4. The partition can be integrated into the existing production line without significantly changing the size of the pin, which facilitates the implementation of the modification.

[0070] Additionally, as attached Figure 8 As shown, this embodiment also provides an assembly method, that is, the partition 5 is fixed to the upper end of the panel 1 to be pressed by screws. When the upper mold 3 moves down, the pin 4 passes through the cleaning cavity 6 on the partition 5 and enters the hollow column groove 2 to complete the compaction. At the moment of passing through, the edge of the cleaning cavity 6 wipes the outer wall of the pin 4, scraping off the adhering powder.

[0071] 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.
