Description

Technical Field

[0001] This utility model belongs to the field of precision manufacturing technology of drug shaped covers, specifically relating to a single-mold electroforming integrated shielding mold frame. Background Technology

[0002] Precision electroforming propellant liner shapes are characterized by high purity, high dimensional accuracy, high surface finish, good consistency, and simplified processing. They also exhibit high and stable armor-piercing performance, hence their widespread application. Electroforming has become one of the main processes in propellant liner production. The shielding device is a crucial component of the electroforming process equipment, and its alignment with the mandrel is a key factor affecting product quality.

[0003] Currently, in the electroforming process of the liner, the shielding position is fixed at the bottom of the electroforming tank, while the core mold is fixed on the power head above the liquid surface. Because the electroforming solution is opaque, it cannot be directly observed manually. When installing the core mold, a person must reach underwater to feel for alignment. Since the mold frame and core mold are quite heavy, alignment is extremely inconvenient and can only be done underwater based on experience and intuition. This makes it difficult to guarantee the assembly quality (alignment) of the core mold and shielding device, easily leading to unstable quality of the electroformed liner. Utility Model Content

[0030] To make the objectives, contents, and advantages of this utility model clearer, the specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0031] refer to Figures 1 to 3The present invention provides a single-mold electroforming integrated shielding mold frame, which is made of polypropylene and includes a core mold support sleeve 1, a core mold support plate 2, a connecting rod 3, an adjusting sleeve 4, a shielding mounting bracket 5, a hexagonal nut 6, a slotted screw 7, a fixing screw 8, a hexagonal head bolt 9, a flat washer 10, a spring washer 11, and a shielding mounting base 12.

[0032] The core mold support sleeve 1 is fixed to the core mold support plate 2 by a combination of hexagonal head bolts 9, flat washers 10, and spring washers 11, forming a detachable connection. Both the core mold support sleeve 1 and the core mold support plate 2 support the core mold. Both are manufactured with high precision and can fit tightly together, minimizing contact between the core mold shank and the electroforming solution. The core mold shank and the core mold support sleeve 1 are radially tightened with fixing screws 8, ensuring that the core mold and mold frame remain relatively fixed and rotate as a whole during electroforming. This guarantees the alignment of the core mold and the shielding mold frame, helping to avoid inconsistent surface plating thickness of the molten metal liner during electroforming and improving product quality. Two symmetrically distributed connecting rods of equal length 3 are used to firmly connect the core mold support plate 2, adjusting sleeve 4, and shielding mounting bracket 5 using hexagonal nuts 6, forming a stable and symmetrical frame structure. The connecting rods 3 have cylindrical ends. The shielding mounting bracket 5 is used to fix the connecting rods 3 and the shielding mounting base 12. The two connecting rods 3 have equal positioning surfaces at both ends, and the gap between the positioning shaft end and the connecting hole of the support plate 2 is small, ensuring that the support plate 2 and the shielding mounting bracket 5 are parallel and aligned. The height between the support plate 2 and the shielding mounting bracket 5 can be adjusted by replacing the adjusting sleeve 4 to accommodate the assembly of various products and types of shielding. The shielding mounting base 12 is fixed to the threaded hole located at the geometric center of the shielding mounting bracket 5 by slotted screws 7, allowing for easy replacement of any shielding mounting base 12.

[0033] Compared with existing shielding installation methods, this utility model adopts an integrated design. By directly installing the core mold and shielding device on the mold frame, the core mold and shielding device form an integrated structure. This enables reliable alignment of the shielding device and the core mold, allowing them to be installed together. Furthermore, the core mold and mold frame remain relatively fixed during the electroforming process, ensuring the assembly quality of the core mold and shielding device and effectively improving the consistency of the electroformed liner.

[0034] Currently, the experimental device of this utility model has been successfully applied to the electroforming process of pharmaceutical liner products in the factory, and can meet the product process and quality requirements.

[0035] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
