Description

Technical Field

[0001] This utility model relates to the field of high vacuum metal die casting technology, and more specifically, to a high vacuum amorphous metal die casting molding mold. Background Technology

[0002] Amorphous metals (also known as metallic glasses) have broad application prospects in high-end consumer electronics due to their excellent mechanical properties, corrosion resistance, and high elastic limit, especially suitable for structural components such as the folding frame of a tri-fold mobile phone, which require extremely high material strength and forming precision. However, during the die-casting process, the melting temperature of amorphous metals approaches 1000℃, far exceeding the die-casting temperature of conventional alloys such as aluminum, magnesium, and zinc, placing more stringent requirements on the high-temperature resistance and vacuum sealing performance of the mold.

[0003] In existing die-casting molds, conventional vacuum systems often employ localized sealing structures in areas such as ejector pins and slides. However, due to the aging and wear of sealing materials under high-temperature environments, it is difficult to maintain a vacuum level above 0.5 MPa, severely impacting the filling quality of the amorphous metal melt and the compactness of the product. Furthermore, traditional molds are prone to seal failure under high temperature and pressure, affecting not only the product molding yield but also leading to low yields and high costs in post-processing steps such as electroplating. Therefore, a high-vacuum amorphous metal die-casting mold is proposed to address these issues. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, embodiments of this utility model provide a high-vacuum amorphous metal die-casting mold. The technical problem to be solved by this utility model is that in existing die-casting molds, conventional vacuum systems often employ local sealing structures in parts such as ejector pins and sliders. However, due to the easy aging and wear of sealing materials under high-temperature environments, it is difficult to maintain the vacuum level above 0.5 MPa, which seriously affects the filling quality of the amorphous metal melt and the density of the product. In addition, traditional molds are prone to sealing failure under high temperature and high pressure, which not only affects the product molding qualification rate but also leads to low yield rates and high costs in post-processing steps such as electroplating.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-vacuum amorphous metal die-casting mold, comprising an upper pressing component, characterized in that: a forming component is provided in the inner cavity of the upper pressing component, and a lower pressing component is provided at the bottom of the upper pressing component; The pressure assembly includes a base block with a cavity and multiple slots on its surface.

In later use, the sealing performance and stability of the product are improved, and a perfect closed loop is formed, which solves the problem of poor sealing durability in the past, improves the vacuuming effect, can quickly assist in product molding, and improves production efficiency.

[0009] In a preferred embodiment, the lower mold and the bottom column are fixedly connected to the cavity at the top of the bottom block by bolts, and the mold groove and the material tube are fixedly connected to the cavity at the bottom of the top block by bolts. The mold groove and the mold block are both fixedly connected by bolts. If the lower mold, mold groove and multiple mold blocks are damaged after prolonged use and affect the quality of the product after molding, the bolts used for connection can be removed and replaced in time to avoid affecting the quality of the product after molding.

[0010] In a preferred embodiment, the connecting plate is fixedly connected to the bottom of the base block after being penetrated by bolts, and the multiple top rollers penetrate multiple top holes; this ensures the stability of the device during use, and the top rollers not only position the base block to prevent misalignment, but also support the top block, thus improving the stability of use.
