Description

Technical Field

[0001] The present application relates to the technical field of hoisting equipment, and in particular to a mold hoisting mechanism for vacuum electromagnetic suspension smelting equipment. Background Art

[0002] The electromagnetic induction vacuum suspension melting method of a water-cooled copper crucible is a melting method that has developed rapidly in recent years. By cutting the copper crucible into equal copper petal structures, electromagnetic Lorentz force is generated during the melting process. The melt is in a semi-suspended state and accompanied by strong stirring. The formed hump allows the metal to separate from the crucible wall, avoiding contamination of the crucible wall; electromagnetic stirring allows the added alloy elements to be mixed quickly and evenly, which has a good effect on the preparation of high melting point, high purity, and extremely active metal materials or metal alloys.

[0003] In order to meet the needs of precision-made parts in different fields, it is generally necessary to design different molds and then prepare precision parts by casting. For metal materials with a melting point of about 1000 degrees, it is not necessary to use high-density graphite molds for casting. High-temperature heat-resistant mold steel has good thermal shock toughness. Compared with graphite molds, it is not easy to crack due to deformation of parts when preparing larger parts. Therefore, it has a longer service life than graphite molds within the temperature range. However, due to the high density of steel (7.9g / cm^3), which is 3.6 times that of graphite (2.2g / cm^3), and in order to improve the vacuum efficiency, the casting cavity position of the suspension smelting equipment is generally small, which makes it very difficult for operators to debug heavy molds in a small space. It is easy for the mold to fall and hit the furnace body, resulting in damage to the mold or furnace body and potential risk of personal injury. Utility Model Content

[0028] The adjusting member is a crank 12, which is rotatably connected to one side of the support seat 7, and is fixedly connected to the winding shaft 8. The winding shaft 8 is driven to rotate by setting the adjusting member. In the illustrated embodiment, the adjusting member is the crank 12, and in other embodiments, the adjusting member is a motor.
