Description

Technical Field

[0001] This invention belongs to the field of pyrotechnics manufacturing technology, and relates to an integrated combination mold design and usage method suitable for automatic loading and pressing of ignition devices. The loading and pressing process in the assembly and production of pyrotechnics can be realized through the design and application of the integrated combination mold to achieve automatic and continuous loading and pressing production of ignition devices and other similar pyrotechnics. Background Technology

[0002] In the pyrotechnics manufacturing industry, the assembly and production of ignition devices often employs modular mold designs. During the loading and pressing of propellants, the various parts of the modular mold need to be frequently and repeatedly disassembled and reassembled depending on the specific process. Personnel must repeatedly handle the propellant and the product to complete the loading or pressing. This process is complex, cumbersome, and physically demanding. Furthermore, the diverse product types and small batch production characteristics of ignition devices result in a large number and variety of modular molds with different specifications. These different molds are incompatible and cannot be directly applied to automated production processes for loading and pressing. Summary of the Invention

[0003] This invention primarily utilizes an integrated mold design to automate the continuous charging and pressing of propellants during the assembly and production of ignition devices. This effectively improves production efficiency, reduces labor costs, and enhances product quality.

[0004] This invention is achieved through the following technical solutions: An integrated combination mold design method for automatic pressing of ignition devices, wherein the combination mold includes a bottom mold, a guide mold, a positioning mold, and a core rod; The bottom mold structure is designed according to the outer diameter of the product and the clamping method of the equipment to meet the functions of automatic gripper clamping, mold assembly process and automatic positioning and guidance during conveying; The guide mold is used to guide the drug during the loading process and to guide the press punch during the pressing process. The guide mold needs to be designed in terms of the opening size and structure of the product, and at the same time, it should be easy to position and combine with the positioning mold. The positioning mold fixes the product, connects the guide mold and the bottom mold, and acts as a transitional connection in the combined mold, so that the automated production line can be used compatiblely according to different products; The core rod is located at the center of the combined mold and is assembled with the bottom mold. It is used for the production of ring-shaped products and also for floating cooperation with the pressing process to ensure the reliability of the pressing.

[0005] The method of using the combined mold designed by the above method is as follows: In the automated assembly of ignition devices, each part of the mold can be moved and assembled by the equipment grippers according to the process requirements of the charging and pressing process. When the mold is transferred to the charging station, the equipment grippers place the bottom mold at the equipment outlet, then insert the core rod into the bottom mold. Next, according to the shape and process of the product, the positioning mold is flipped and inserted into the bottom mold, and then the guide mold is inserted, completing the assembly of each part of the mold before charging. During the mold assembly process, the guide mold can be selectively flipped and the core rod can be selectively inserted according to the product type and process. After the combined mold is assembled, the equipment lifts it up, and the upper surface of the guide mold is aligned with the... The equipment connects to the drug outlet for drug loading; when the mold process reaches the drug pressing station, the combined mold is lifted by the equipment, the press is pressed down, and the press head and core rod are automatically aligned and aligned to press the drug. After pressing, the press is lifted and automatically disengages from the combined mold core rod. At the drug pressing station, the guide mold can be automatically and selectively replaced by the equipment's grippers according to the different products, thereby achieving compatible production of multiple mold products. After drug loading and pressing, the combined mold is then gripped in reverse order according to the assembly sequence by the grippers, disassembled into individual parts, placed on a pallet and transferred to the starting position, and then prepared for reassembly production, thereby realizing automatic cyclic production of the mold.

[0006] This integrated loading and pressing mold can also selectively perform deep cleaning of each part of the mold during the disassembly process, depending on the different performance requirements of the drug.

[0007] This integrated assembly and pressing mold design enables automated production of ignition products, effectively improving the inherent safety of the production process, reducing safety hazards, and increasing production efficiency and product quality.

[0008] Compared with the prior art, the beneficial effects of the present invention are: 1. The design of this combined mold enables fully automated and unmanned production of ignition devices in the process of loading and pressing propellants, solving the problem of manual loading of propellants in the original process, and improving inherent safety and production efficiency; 2. The integrated combination mold design, combined with the automatic picking and placing of the equipment's grippers, results in higher consistency and can effectively improve the quality of loading and pressing drugs.

[0009] 3. The integrated modular mold allows the equipment to automatically and selectively assemble the various parts of the mold according to the product type and process, enabling flexible production of the drug loading and pressing process and effectively improving product compatibility.

[0010] 4. After the assembly and pressing are completed, the combined mold can be disassembled. At the same time, depending on the performance requirements of the agent, especially when producing agents with strong adhesion, each part can be cleaned. Through deep cleaning, the problem of drug spillage from the mold itself during the production process is effectively reduced, thereby effectively improving the inherent safety of this production line.

[0011] 5. It provides technical support for the automation of the assembly and production of ignition devices and other pyrotechnic products. Attached Figure Description

Detailed Implementation

[0013] The technical solution adopted in this invention is: A combined mold consisting of a base mold, a guide mold, a positioning mold, and a core rod is designed for automated assembly of ignition devices. Each part of the mold can be moved and assembled by the equipment's grippers according to the process requirements of the charging and pressing operations. This solves the problem of repeated manual clamping of molds during the assembly of ignition devices, thus achieving fully automated and unmanned production of the charging and pressing process. When the mold reaches the charging station, the equipment grippers place the base mold at the charging port, then insert the core rod into the base mold. Next, the positioning mold is flipped and inserted into the base mold according to the product's shape and process, followed by the guide mold. This completes the assembly of the mold parts before charging. During the assembly process, the guide mold can be selectively flipped and the core rod selectively inserted depending on the product type and process. After the combined mold is assembled, the equipment lifts it up, aligning the upper surface of the guide mold with the charging port for charging. When the mold reaches the pressing station, the combined mold is lifted by the equipment, the press is pressed down, and the press head and core rod are automatically aligned and aligned to press the drug. After pressing, the press is lifted and automatically disengages from the core rod of the combined mold. At the pressing station, the guide mold can be automatically and selectively changed by the equipment's grippers according to the different products, thus achieving compatible production of multiple mold products. After loading and pressing, the grippers reverse the assembly sequence of the combined mold, disassembling it into individual parts and placing them on a pallet to be transferred to the starting position, then preparing for reassembly production, thus achieving automatic cyclical production of the mold. This integrated loading and pressing mold design also allows for selective deep cleaning of different parts of the combined mold during the disassembly process, depending on the performance requirements of the drug.

[0014] The following is in conjunction with the appendix Figure 1-5 Further details on specific embodiments of the present invention are provided below: Figure 1The invention's structural schematic diagram is shown, including: bottom mold 5, guide mold 3, positioning mold 2, and core rod 4.

[0015] The bottom mold structure is designed based on the product's outer diameter and the equipment's clamping method, satisfying the automatic gripper's clamping, mold assembly process, and automatic positioning and guiding functions during conveying. A structural diagram is shown below. Figure 2 As shown.

[0016] The guide mold is mainly used for guiding the drug during the loading process and for guiding the pressing punch during the compression process. The guide mold needs to be designed with specific dimensions and structure for the opening of the product, while also facilitating positioning and assembly with the positioning mold. A structural diagram is shown below. Figure 3 As shown.

[0017] Positioning module structure such as Figure 4 As shown, it fixes the product, connects the guide mold and the bottom mold, and acts as a transitional connection in the combined mold, so that the automatic production line can be used compatiblely according to different products.

[0018] The core rod is located at the center of the assembly mold and is assembled with the bottom mold. It is used for the production of ring-shaped products and also serves to ensure the reliability of the pressing process by floating and engaging with the pressing material. Figure 5 As shown.

[0019] In practical use, this integrated mold effectively solves the problem of automated and unmanned production of ignition devices during the loading and pressing of propellant. It also improves the compatibility of different product types during production and enhances the flexibility of the automated production line. This effectively improves product quality and the fundamental nature of the production process.
