Description

Technical Field

[0001] The utility model relates to the technical field of lost foam, in particular to a guide and limiting device for a lost foam mould. Background Art

[0002] Lost foam casting is a solid casting method that uses a foam plastic mold with binder-free dry sand combined with vacuum technology. Lost foam casting is a new type of casting that combines paraffin or foam models with similar size and shape to the casting into a mold, and then paints refractory paint on the mold and dries it. It is then buried in dry quartz sand for shaping, and finally poured under negative pressure to vaporize the mold, allowing liquid metal to occupy the position of the mold, and finally the liquid metal solidifies and cools to form a casting.

[0003] However, the length of the delivery pipe used to guide and transport the metal liquid in the existing processing box is fixed, and the delivery pipe cannot be inserted into the mold according to the molds of different heights; secondly, after the mold is placed in the processing box and filled with quartz sand, part of the quartz sand cannot fit the outer wall of the mold, which will cause deviations in the shape and size of the casting after the final molding, thus affecting the use of the casting.
