Description

Technical Field

[0001] This utility model relates to the field of casting device technology, specifically a multi-station casting device for investment casting. Background Technology

[0002] A gating system for investment casting is a specialized device for injecting molten metal into an investment mold. Its core function is to accurately and stably complete the filling of the mold with molten metal, ensuring the formation and quality of the casting. Core definition: A gating system for investment casting is a molten metal injection device adapted to the structure of lost-wax casting molds, encompassing a complete mechanism from molten metal transfer and quantitative control to mold spout connection. It needs to match the characteristics of investment casting—"fine molds and complex castings"—meeting the requirements for precise injection and avoiding mold damage. Main functions: Precise delivery of molten metal: Controlling the flow rate, velocity, and injection volume of the molten metal to ensure that the liquid metal completely fills the small cavities and complex structures of the mold. Protection of mold and casting: Preventing mold breakage due to excessive impact from molten metal, while reducing splashing and oxidation, and minimizing defects such as porosity and inclusions in the casting. Improved operational safety: Isolating the high-temperature molten metal from operators, reducing safety risks such as burns and splashes, and replacing or assisting manual pouring. Adaptable to production needs: It can perform manual, semi-automatic or fully automatic operations according to batch size and casting complexity, balancing flexibility and efficiency.

[0003] However, most traditional investment casting devices are single-station operations, requiring molds to be changed one by one, resulting in extremely low casting efficiency. They also lack a unified mold fixing mechanism, making it easy for molds to shift during casting, leading to molten liquid leakage and poor casting accuracy. In addition, traditional devices lack a molten liquid buffering and filtering process, and impurities in the molten liquid can easily cause casting defects. Furthermore, the mold movement is mostly done manually, which is inaccurate and labor-intensive.

[0004] Based on this, the present invention provides a multi-station casting device for investment casting to solve the above-mentioned technical problems. Utility Model Content
