Dual-power pressure type large-size ceramic target material forming mold and method thereof

Abstract

The invention discloses a dual-power pressure type large-size ceramic target material forming mold and a method thereof. Under the condition that one set of mold can only mold a target material of one specification, demolding operation is tedious, secondary damage is easily caused to the molded target material, and the molding quality of corners is poor. According to the mold, a lower mold ring body sleeves a lower mold core, a lifting hole matched with the lower mold core is formed on a base, the lower mold core ascends or descends in the height direction of the lifting hole, the top surface of the lower mold core is a lower pressing surface, a pressing ring is arranged above the base, a plurality of elastic limiting pieces are arranged between the base and the pressing ring, the adjusting direction of the elastic limiting pieces is the same as the lifting direction of the lower mold core, an upper mold core is arranged above the pressing ring in a matched mode, an upper positioning sleeve sleeves the outside of the upper mold core, and a cavity with the adjustable volume is defined among the upper pressing face of the upper mold core, the pressing ring, the base and the lower pressing face of the lower mold core.

Description

technical field [0001] The invention specifically relates to a dual-dynamic pressure type large-size ceramic target molding die and a method thereof. Background technique [0002] Powder die-casting is an important process for preparing targets in material engineering. It applies pressure to the forming mold through a press, so that the material powders are bonded by PVA to form a solid target. The shape of the target is usually a cylindrical sheet. Since the size and thickness of most targets are small, the strength of the mold and the power of the press are relatively low. The current powder die-casting molds are mostly loaded axially by a single-power press, and the powder of this loading method Die-casting molds are not suitable for mold release and multi-size target powder molding, especially when the target size and thickness are large, due to the limitations of the size, structure and power of the mold itself, it cannot be achieved. Real-time adjustment of the height...
