casting shelling machine

Abstract

The invention discloses a casting casing remover comprising a frame. The frame comprises stand columns and an upper cross beam. Two vertical guide rails are fixed on the upper cross beam. A mounting plate is vertically and slidably mounted on the guide rails. A vibrating gun is fixedly mounted on the mounting plate. A vibrating rod of the vibrating gun is arranged downwards. A touch switch for opening the vibrating gun is arranged at the top of the vibrating gun. A plug seat is arranged on the mounting plate and above the vibrating gun, and is connected with a vertical push rod through a plug. The push rod is driven by a power device. Upward and downward movement positions of the mounting plate are limited by a limit device. The casting casing remover can remove casting casings rapidly; dynamic during casing removing is easy to control, so that damage to surfaces or internal structures of castings due to overexertion is avoided, and the rate of finished products is increased.

Description

technical field [0001] The invention relates to a shelling machine, in particular to a casting shelling machine utilizing the principle of vibration. 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. ", at this time the wax model is the same size as the real thing (the actual size is enlarged according to the casting shrinkage ratio), and then the surface of the wax model is covered with sand to a certain thickness. This step is called "staining sand". After the casting sand on the surface of the mold is bonded, the sand-covered wax mold is boiled in water, and the wax is boiled to leave a sand shell. This step is called "boiling wax". Finally, the sand shell is buried in the casting sand pit to melt the molten iron The sand shell is poured in, and the molten iron left in th...

Problems solved by technology

After the casting is formed, the sand on the surface of the casting needs to be crushed to take out the casting. At present, the method of manual hammering is generally used. This method not only has a very low efficiency of shelling, but also uses hard objects to knock it out The force cannot be controlled, and the surface or interior of the casting may be damaged due to excessive knocking, which has a negative impact on the quality of the casting and reduces the yield of the casting.
