Description

Technical Field

[0001] This utility model relates to the field of propellant processing technology, and in particular to a modular compression mold for irregularly shaped propellants. Background Technology

[0002] Irregularly shaped propellants need to be molded during the production process. In existing technologies, integral molds or simple split molds are mostly used to complete the pressing operation.

[0003] However, when using integral molds to press irregularly shaped propellants, the special shape of the propellant leads to close contact between the inner wall of the mold and the surface of the propellant during the demolding stage, significantly increasing the demolding resistance. This can easily cause damage to the edges and corners of the propellant, resulting in chipping and directly affecting the product molding quality. At the same time, the friction between the mold and the propellant during demolding can easily generate heat, and since propellants are flammable and explosive, such heat generation may cause safety accidents.

[0004] While some split molds attempt to improve demolding issues, they often employ a single drive source or a simple guiding structure, making it difficult to ensure the synchronization of the movements of multiple split mold segments. During the pressing stage, the split mold segments are prone to sealing failure due to loose fit, leading to powder leakage and failing to meet the density requirements for high-pressure propellant molding. During the demolding stage, uneven dispersion of the split mold segments may result in excessive friction between the propellant grain and the inner wall of the mold, failing to fundamentally solve the risks of propellant grain damage and heat generation.

[0005] To address the aforementioned problems, this utility model document proposes a modular compression mold for irregularly shaped propellants. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies, such as high demolding resistance of integral molds, easy damage to propellant, easy friction and heat generation, and significant safety hazards; and the lack of synchronization and excessive friction of some split molds. Therefore, this invention proposes a split-type combined compression mold for irregularly shaped propellants.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A modular compression mold for irregularly shaped propellants includes:

[0009] The base has an extension bracket fixedly installed on one side. The base and the extension bracket are provided with the same top plate. The bottom of the top plate is fixedly connected to the top of the base and the extension bracket by multiple support rods.

[0010] It also includes an upper mold and a lower mold. The top of the upper mold is provided with a moving mechanism, which enables the upper mold to move horizontally and move up and down accordingly. The lower mold is composed of multiple split mold pieces, which are tightly fitted and sealed together. The lower mold cooperates with the upper mold to complete the pressing and molding of the powder.

[0011] It also includes a drive mechanism, which is used to disperse and aggregate multiple split mold segments to adjust the degree of expansion of the lower mold.

[0012] In one possible design, the moving mechanism includes a movable frame slidably disposed on the top of a top plate. A second cylinder is fixedly inserted through the top of the movable frame, and two guide rods slide through the top of the movable frame. The two guide rods are located on both sides of the second cylinder, and the bottom ends of the two guide rods are fixedly connected to the top of the upper mold. One end of the piston rod of the second cylinder is fixedly connected to the top of the upper mold. The top of the top plate has three corresponding sliding grooves, which respectively cooperate with the second cylinder and the two guide rods to ensure the stable sliding of the movable frame on the top of the top plate. A first cylinder is fixedly installed on the top of the top plate, and one end of the piston rod of the first cylinder is fixedly connected to one side of the movable frame to realize the horizontal push-pull drive of the movable frame.

[0013] In one possible design, the driving mechanism includes a fixed plate fixedly mounted on the top of the base, a fixed seat fixedly mounted on the top of the fixed plate, and a cover plate fixedly mounted on the top of the fixed seat. A rotating plate is rotatably mounted inside the fixed seat. The top of the rotating plate has a first limiting groove. The top of the fixed seat has multiple second limiting grooves via a bracket, each corresponding to a multiple split mold piece. The top of the cover plate has multiple through grooves corresponding to the second limiting grooves. Each of the multiple split mold pieces slides into contact with the top of the cover plate. A fixed post is fixedly mounted at the bottom of each of the multiple split mold pieces. One end of each fixed post passes through a corresponding second limiting groove and slides through the inner wall of the first limiting groove, allowing the fixed post to move back and forth within the second limiting groove via the limiting drive of the first limiting groove. A limiting nut is threaded onto the outer wall of the fixed post via an external thread. The limiting nut is located below the second limiting groove and close to the top inner wall of the fixed seat, thus horizontally limiting the split mold pieces and ensuring stable movement of the multiple split mold pieces.

[0014] In one possible design, the driving mechanism further includes a lever plate fixedly mounted on the outer wall of the rotating plate. The bottom of the fixed base has an adjustment groove. One end of the lever plate extends to the outside of the fixed base through the corresponding adjustment groove. A clearance hole is provided near one end of the lever plate, and a connector is hinged to the lever plate through the clearance hole. A cylindrical slider, which is a T-shaped cylinder, is fixedly mounted on one end of the connector. A fixed bracket is fixedly mounted on one side of the base. A lifting plate is slidably mounted inside the fixed bracket. A guide groove is provided on one side of the lifting plate. The guide groove is inclined, and the cylindrical slider slides in cooperation with the inner wall of the guide groove. When the lifting plate rises or falls, it can drive the connector to move horizontally, thereby actuating the lever plate to rotate the rotating plate. A fourth cylinder is fixedly mounted on the bottom of the fixed bracket. One end of the piston rod of the fourth cylinder slides through the bottom inner wall of the fixed bracket and is fixedly connected to the bottom of the lifting plate to complete the lifting and lowering drive of the lifting plate.

[0015] In one possible design, a third cylinder is fixedly installed inside the base. One end of the piston rod of the third cylinder slides through the top of the base. The center of the fixed plate, rotating plate, fixed seat, and cover plate are all provided with passages. One end of the piston rod of the third cylinder extends through the passage to the top of the cover plate and is fixedly installed with an abutment plate. The bottom inner walls of the multiple split mold pieces are provided with grooves at their close ends. The multiple grooves are combined to form a circular groove. The abutment plate is tightly fitted and sealed to the inner wall of the circular groove to ensure that the irregularly shaped propellant is lifted after molding to facilitate material removal.

[0016] In one possible design, a controller is fixedly mounted on one side of the base to control the device.

[0017] In this application, when in use, the piston rod of the fourth cylinder is pushed upward, at which time the multiple split mold pieces are tightly attached to each other and sealed together, and the abutment plate is tightly attached to the inner wall of the circular groove formed by the bottom of the multiple split mold pieces. At this time, propellant powder can be added into the mold cavity formed by the multiple split mold pieces.

[0018] After the powder is added, the first cylinder is activated. When its piston rod extends, it can push the moving frame to slide along the slide groove on the top of the top plate, which can move the upper mold to a position directly above the lower mold. Then the second cylinder is activated. Its piston rod extends downward, which can drive the guide rod to move downward synchronously with the upper mold. The upper mold gradually fits against the top of the mold cavity of the lower mold and applies pressure to the powder in the mold cavity until the powder is pressed into an irregular propellant.

[0019] After the propellant is formed, the piston rod of the second cylinder retracts upward, moving the upper mold upward to its initial height. Then, the piston rod of the first cylinder retracts, pulling the moving frame and the upper mold horizontally, moving it away from the top of the lower mold. Next, the fourth cylinder actuates, its piston rod retracts downward, and under the guidance of the guide groove, it drives the connector to move horizontally. When the connector moves, it drives the lever plate to move synchronously, thereby driving the rotating plate to rotate inside the fixed seat. The first limiting groove on the rotating plate rotates with the rotating plate, and its inner wall slides with the fixed column. Through the abutment and limitation of the limiting groove, multiple fixed columns can be pushed outward along the corresponding second limiting groove, thereby realizing the separation of multiple split mold segments to complete the expansion of the lower mold and achieve "zero coefficient" separation between the inner wall of the mold and the surface of the propellant. Then, the third cylinder actuates, its piston rod extends upward, which drives the abutment plate to move upward and abut against the bottom of the formed propellant, lifting it upward until the propellant moves to a height that is easy to pick up. After that, the formed propellant can be directly removed.

[0020] After the material is picked up, the piston rod of the fourth cylinder is pushed upward again, which can bring the multiple split mold pieces closer together. Then the piston rod of the third cylinder is retracted, and the lower mold can be restored to the state before processing started. Then the powder can be replenished again to start a new round of processing. During the processing, the controller can adjust the timing and stroke of each cylinder to ensure the precise coordination of the actions of each component.

[0021] Beneficial effects: In this utility model, the modular combination pressing mold for irregularly shaped propellants, through the moving mechanism of the upper mold, can achieve precise control of the horizontal movement and lifting of the upper mold, which facilitates material handling and ensures accurate alignment between the upper and lower molds during pressing, effectively reducing molding quality problems caused by misalignment. The lower mold is composed of multiple modular mold pieces, which, together with the driving mechanism, complete the dispersion and aggregation drive. During the demolding stage, it can drive the multiple modular mold pieces to slide outward synchronously, so that the inner wall of the mold and the surface of the formed propellant column can achieve "zero coefficient" separation, greatly reducing demolding resistance, avoiding damage to the edges and corners of the propellant column, and reducing the heat generated by demolding friction. This meets the characteristics of propellants that are flammable and explosive and need to avoid heat generation, significantly improving production safety.

[0022] In this invention, a modular compression mold for irregularly shaped propellants utilizes a drive mechanism. A guide groove on a lifting plate slides against a cylindrical slider, driving a rotating plate to rotate. The rotating plate then uses a first limiting groove on the rotating plate to engage with a fixed column, propelling multiple mold segments to move. This transmission structure ensures synchronized movement of the multiple mold segments, achieving tight fit and sealing during the compression stage to prevent powder leakage and guarantee the density required for high-pressure propellant molding. A limiting nut on the outer wall of the fixed column, tightly attached to the inner top wall of the fixed base, provides stable horizontal positioning for the mold segments, preventing deviation during movement and further improving molding accuracy.

[0023] In this utility model, the three-part combination compression mold for irregularly shaped propellants has a third cylinder inside the base that drives the abutment plate to rise and fall. After molding, the propellant column can be lifted upward to a position that is easy to pick up, eliminating the need for manual access to the mold area to pick up the material, thus improving the convenience of material picking and operational efficiency, and reducing operational risks.

[0024] In this invention, the mold uses a moving mechanism to achieve horizontal movement of the upper mold, facilitating material removal; the lower mold's multi-segment structure, combined with a drive mechanism, allows for synchronous separation during demolding, achieving "zero-coefficient" demolding, reducing frictional resistance, minimizing frictional heat generation, and ensuring safe production; the third cylinder can eject the material after processing, eliminating the need for manual material removal, improving efficiency, and reducing risk; the controller enables automatic operation of the equipment, balancing high-pressure molding and low-resistance demolding, ensuring the quality of the medicament and meeting the needs of mass production.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0031] In one embodiment: Refer to Figure 1-4 A pressing mold includes: a base 1, an extension bracket 2, a top plate 3, an upper mold 8, a lower mold 9, a moving mechanism, a driving mechanism, and a controller 10.

[0032] In this embodiment, the base 1 serves as the basic support component of the entire mold, and an extension bracket 2 is fixedly installed on one side of it; the same top plate 3 is provided above the base 1 and the extension bracket 2, and the bottom of the top plate 3 is fixedly connected to the top of the base 1 and the extension bracket 2 through multiple support rods to form a stable frame structure.

[0033] In this embodiment, the upper mold 8 and the lower mold 9 are key components for completing the powder pressing and molding. The upper mold 8 is provided with a moving mechanism at its top, which enables the upper mold 8 to move horizontally and rise and fall. Specifically, the moving mechanism includes a moving frame 4 that is slidably disposed on the top of the top plate 3. The top of the moving frame 4 is fixedly connected to the second cylinder 6, and two guide rods 7 are slidably connected to it. The two guide rods 7 are located on both sides of the second cylinder 6, and the bottom ends of the guide rods 7 are fixedly connected to the top of the upper mold 8. One end of the piston rod of the second cylinder 6 is also fixedly connected to the top of the upper mold 8. Three corresponding sliding grooves are opened on the top of the top plate 3, which cooperate with the second cylinder 6 and two guide rods 7 respectively to ensure that the moving frame 4 slides stably on the top of the top plate 3. The top of the top plate 3 is also fixedly installed with the first cylinder 5. One end of the piston rod of the first cylinder 5 is fixedly connected to one side of the moving frame 4. When it is necessary to move the upper mold 8 horizontally, the first cylinder 5 is activated, and its piston rod extends and retracts to push the moving frame 4 to slide horizontally on the top of the top plate 3, thereby driving the upper mold 8 to move horizontally. When it is necessary to raise and lower the upper mold 8, the second cylinder 6 is activated, and its piston rod extends and retracts to drive the upper mold 8 to rise and fall.

[0034] In this embodiment, the lower mold 9 is composed of multiple split mold segments 20, which are tightly fitted and sealed together, and cooperate with the upper mold 8 to complete the pressing and molding of the powder; wherein, the driving mechanism is used to disperse and aggregate the multiple split mold segments 20 to adjust the degree of expansion of the lower mold 9.

The multiple split mold segments 20 slide in cooperation with the top of the cover plate 19, and a fixed post 22 is fixedly mounted on its bottom. One end of the fixed column 22 passes through the corresponding second limiting groove 18 and is slidably connected to the inner wall of the first limiting groove 15. When the rotating plate 14 rotates, the limiting effect of the first limiting groove 15 allows the fixed column 22 to move back and forth in the second limiting groove 18, thereby realizing the dispersion and aggregation of multiple split mold pieces 20. Furthermore, the outer wall of the fixed column 22 is fitted with a limiting nut 23 through an external thread. The limiting nut 23 is located below the second limiting groove 18 and close to the top inner wall of the fixed base 17, which can complete the limiting of the split mold pieces 20, prevent the multiple split mold pieces 20 from tilting during movement, and ensure the stable movement of the multiple split mold pieces 20.

An adjustment groove is provided at the bottom of the fixed base 17, and one end of the lever 16 extends to the outside of the fixed base 17 through the corresponding adjustment groove. A clearance hole 24 is provided near one end of the lever 16, and a connector 25 is hinged through the clearance hole 24. A cylindrical slider 26 is fixedly installed at one end of the connector 25.

An inclined guide groove 28 is provided on one side of the lifting plate 27, and the cylindrical slider 26 slides in cooperation with the inner wall of the guide groove 28. When the lifting plate 27 rises and falls, it can drive the connector 25 to move horizontally, thereby actuating the lever 16 to drive the rotating plate 14 to rotate. A fourth cylinder 30 is fixedly installed at the bottom of the fixed bracket 29. One end of the piston rod of the fourth cylinder 30 slides through the inner wall of the bottom of the fixed bracket 29 and is fixedly connected to the bottom of the lifting plate 27. The lifting and lowering of the lifting plate 27 can be achieved by extending and retracting the piston rod of the fourth cylinder 30.

[0037] This application can be used in the field of propellant processing technology, or in other fields applicable to this application.

[0038] In another embodiment: Reference Figure 1 , 2 A modular compression mold for irregularly shaped propellants is applied to the field of propellant processing technology. The structure of this embodiment is basically the same as that of the aforementioned embodiments, except that:

[0039] In this embodiment, a third cylinder 11 is fixedly installed inside the base 1. One end of the piston rod of the third cylinder 11 slides through the top of the base 1. Passages are opened in the center of the fixed plate 13, the rotating plate 14, the fixed seat 17, and the cover plate 19. One end of the piston rod of the third cylinder 11 extends through the passage to the top of the cover plate 19 and is fixedly installed with the abutment plate 12. Grooves 21 are opened at the bottom inner walls of the multiple split mold pieces 20 that are close to each other. The multiple grooves 21 are combined to form a circular groove. The abutment plate 12 is tightly attached to the inner wall of the circular groove and is sealed. When the powder is pressed into shape, the third cylinder 11 is activated, and its piston rod extends, driving the abutment plate 12 to move upward, lifting the shaped propellant after it is formed, making it easy to pick up the material.

[0040] In this embodiment, a controller 10 is fixedly installed on one side of the base 1. The controller 10 can control each cylinder in the equipment and realize the automated operation of the equipment.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of the first cylinder 5, the second cylinder 6, the third cylinder 11 and the fourth cylinder 30 are all conventional means or common knowledge, and will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience.

[0042] The working principle and usage process of this technical solution are as follows: When in use, the piston rod of the fourth cylinder 30 is pushed upward. At this time, multiple split mold pieces 20 are tightly attached to each other and sealed together. The abutment plate 12 is tightly attached to the inner wall of the circular groove formed by the bottom of multiple split mold pieces 20. At this time, propellant powder can be added into the mold cavity formed by the multiple split mold pieces 20.

[0043] After the powder is added, the first cylinder 5 is activated. When its piston rod extends, it can push the moving frame 4 to slide along the slide groove on the top of the top plate 3, which can move the upper mold 8 to a position directly above the lower mold 9. Then the second cylinder 6 is activated. Its piston rod extends downward, which can drive the guide rod 7 to move downward synchronously with the upper mold 8. The upper mold 8 gradually fits against the top of the mold cavity of the lower mold 9 and applies pressure to the powder in the mold cavity until the powder is pressed into an irregular propellant.

[0044] After the irregularly shaped propellant is formed, the piston rod of the second cylinder 6 retracts upward, causing the upper mold 8 to move upward to its initial height. Then, the piston rod of the first cylinder 5 retracts, pulling the moving frame 4 and the upper mold 8 horizontally, moving them away from above the lower mold 9. Next, the fourth cylinder 30 actuates, its piston rod retracting downward, which, guided by the guide groove 28, drives the connector 25 to move horizontally. As the connector 25 moves, it drives the lever 16 to move synchronously, thereby driving the rotating plate 14 to rotate inside the fixed base 17. The first limiting groove 15 on the rotating plate 14 rotates with the rotating plate 14. The inner wall slides with the fixed column 22. Through the abutment and limitation of the limiting groove 15, multiple fixed columns 22 can be pushed to move outward along the corresponding second limiting groove 18, thereby realizing the separation of multiple split mold pieces 20 to complete the expansion of the lower mold 9. The inner wall of the mold and the surface of the propellant can be separated with a "zero coefficient". Then the third cylinder 11 is activated, and its piston rod extends upward, which can drive the abutment plate 12 to move upward and abut against the bottom of the shaped propellant after it is formed, so as to lift it upward until the shaped propellant moves to a height that is easy to pick up. Then the formed shaped propellant can be directly taken out.

[0045] After the material is picked up, the piston rod of the fourth cylinder 30 is pushed upward again, which can bring the multiple split mold pieces 20 closer together again. Then the piston rod of the third cylinder 11 is retracted, and the lower mold 9 can be restored to the state before the start of processing. Then the powder can be replenished again to start a new round of processing. During the processing, the controller 10 can adjust the timing and stroke of each cylinder to ensure the precise coordination of the actions of each component.

[0046] The accompanying drawings in this application are for illustrative purposes only. The dimensions and shapes of the components shown are not actual limitations but are merely schematic representations. In actual implementation, the components can be reasonably configured and adjusted according to specific needs and actual conditions.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
