Abstract

The invention discloses a mold opening device for an aviation blade wax mold, comprising a first mold opening and a second mold opening, the first mold opening is connected with a moving mold of the wax mold, and the second mold opening is connected with the wax mold The fixed mold connection; the first open template and the second open template are connected by a relatively movable arc guide structure, and the arc guide structure includes an arc guide channel and at least two moving in the arc guide channel Guide moving elements, the center of the circular arc guide channel coincides with the center of the blade; the circular arc guide channel is arranged on the first or second open template, and the guide moving element is arranged on the second open template or the second open template Open the template. The mold opening device can solve the problems that the mold is too long and the equipment used in the mold has size limitations, and is especially suitable for long aviation blades.

Description

technical field [0001] The invention relates to an aviation blade manufacturing device, in particular to an aviation blade wax mold opening device. Background technique [0002] In the production of aero-engine blades, the process of melting wax casting is generally used to complete the manufacture of blades. First, the surface of the wax pattern is wrapped with refractory materials, and after the wax is lost in the investment mold, it is baked at high temperature to form a shell, and then poured; the pouring is completed Finally, it needs to go through the mold opening process to get the blade. Among them, since the blade crown and the tenon airway surface of the blade are surfaces that rotate around the center of the engine (the center of the blade), and the airway surface is also a very critical non-machined surface, it is necessary to follow these airway surfaces when opening the mold. The track of the road surface is released from the mold, that is, it must be rotated ...
