Engine guide vane wax pattern placing device

Abstract

The invention relates to the technical field of investment precision casting and discloses an engine guide vane wax pattern placing device which comprises a base, wherein a refrigerating mechanism and a plurality of buffering mechanisms are fixedly connected to the upper surface of the base, a placing box is fixedly connected to the top ends of the buffering mechanisms, a plurality of supporting net plates are fixedly connected to the inner wall of the placing box, a plurality groups of of placing mechanisms are fixedly connected to the upper surface of each supporting net plate, a rectangular inlet hole is formed in the side wall of the placing box, and a side plate is hinged to the outer wall of the placing box through a hinge. The engine guide vane wax pattern placing device has the capacity of cooling, shape preserving and reliable placing. Meanwhile, an engine guide vane wax pattern has a buffering protection function when the placing device moves, so that the safety and reliability of the engine guide vane wax pattern placed by the device are improved, the machining precision and quality of an engine guide vane can be guaranteed, and the yield of mass production of the engine guide vanes can further be guaranteed.

Description

technical field [0001] The invention relates to the technical field of investment precision casting, in particular to a device for placing a wax mold of an engine guide vane. Background technique [0002] "Wax mold" is a common casting method. First, the mold of the workpiece is made of aluminum, and then the wax is injected into the mold. This step is called "waxing", and then the wax mold is taken out after the wax cools down. At this time, the wax model is the same size as the real thing, and then the surface of the wax model is covered with sand to a certain thickness. This step is called "sanding". After the casting sand on the surface of the wax model is bonded, it will The sand-filled wax model is boiled in water to boil the wax and finally leave a sand shell. This step is called "boiling wax". Finally, the sand shell is buried in the casting sand pit and molten iron is poured into the sand shell. The guide vane is the aero-engine. 1. One of the important parts of th...

Problems solved by technology

[0003] Wax pattern preparation is one of the important processes of investment precision casting. The dimensional accuracy of the wax pattern directly affects the dimensional accuracy of the casting blank. However, it is affected by many factors such as the temperature of the wax pattern workshop and the placement of the wax pattern. It is very difficult. For example, if the temperature around the wax mold is high, the surface of the wax mold will be softened and deformed, and the overall shape of the wax mold has a large arc. If it is placed directly, the wax mold will be easily deformed by gravity, which will not only affect the processing of the engine guide vane. Accuracy and quality also affect the qualified rate of mass production of engine guide vanes
