Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for loading explosive materials, particularly viscous ones, face challenges in achieving effective casting due to high viscosity, which complicates the process and results in poor loading quality.
Innovation Solution
A method and device that utilize a sealed pouring vessel with a funnel to create a vacuum both in the tank and the ammunition body, allowing for controlled vacuum casting by maintaining a deeper vacuum level in the body than in the tank, facilitating the flow of viscous explosive materials into the ammunition body.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If conventional gravity casting is used for viscous explosives, then the process is simple, but the loading quality is poor and filling is incomplete
Solution Approach 1:
The patent applies vacuum technology (pneumatic principle) to create a pressure differential between the casting tank and ammunition body. By maintaining a deeper vacuum level in the ammunition body than in the tank, the system overcomes the high viscosity of explosive materials and enables complete filling, thereby improving loading quality while maintaining process feasibility.
2Manufacturing precision
If vacuum casting is applied to viscous explosives, then loading quality improves, but the process complexity increases
Solution Approach 1:
The patent applies local quality by creating different vacuum levels in different zones of the system. Specifically, a deeper vacuum is maintained in the ammunition body compared to the casting tank, which locally optimizes the pressure differential to drive viscous explosive material filling while avoiding excessive complexity in the overall system.
3Reliability
If a sealed funnel connection is used, then vacuum control is improved, but the device structure becomes more complex
Solution Approach 1:
The patent introduces a sealed funnel as an intermediary component between the casting tank and ammunition body. This funnel enables controlled vacuum transmission and maintains the pressure differential necessary for filling viscous explosives, thereby improving vacuum control and reliability while adding only moderate structural complexity.

AI summary
The subject of the invention is a method of casting an explosive material into a munition body (2), in which method the explosive material is placed in the liquid or pasty state in the body (2) by means of a casting tank (4) placed above the munition body. This method is characterized in that the material is vacuum-cast into the munition body (2), the vacuum being created in the tank (4) on the one hand and in the munition body (2) on the other before the casting operation is carried out, the vacuum in the munition body (2) being higher than the vacuum in the tank (4). The subject of the invention is also a casting device for implementing such a method.
