Casting shelling and cleaning device

Abstract

The invention discloses a casting shelling and cleaning device. The casting shelling and cleaning device comprises a rack; a roller is arranged on the rack and internally provided with a rolling shaft in a rotary mode, the rolling shaft is provided with a spiral blade, and the roller is provided with a feeding port and a discharging port which is connected with a discharging cylinder; an opening is formed in the side wall of the discharging cylinder, a cavity is formed in the inner side wall of the discharging cylinder and internally provided with a piston in a slidable mode, and the piston is connected with a piston rod; a baffle is hinged to the discharging port, a first spring is connected between the baffle and the piston rod, and a filter net is connected with the opening and a casting collecting box; a spray head is arranged above the filter net, a waste water collecting box and a water supply box are arranged below the filter net, and the water supply box is provided with a water pump; and a first connecting pipe communicates between the water supply box and the cavity and is provided with a one-way valve, and a second connecting pipe is arranged between the cavity and the spray head. Compared with the prior art, the casting shelling and cleaning device is even in stress and easy to operate during sand shell separating.

Description

technical field [0001] The invention relates to a casting processing device, in particular to a casting shelling and cleaning device. Background technique [0002] "Wax mold" is a common casting method. First, the mold of the workpiece is made of aluminum, and then the step of injecting wax into the mold is called "waxing". 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 "sanding", etc. After the casting sand on the surface of the wax model is bonded, put the sand-covered wax model into water to boil. The wax is boiled and finally a sand shell is left. This step is called "boiling wax". Finally, the sand shell is buried in the casting sand pit. The molten iron is poured into the sand shell, and the molten iron left in the sand mold cools down and becomes a casting. After the casting is ...

Problems solved by technology

[0004] This cast shelling machine solves the shortcomings of the artificial hammering method, but it still has the following disadvantages: when the vibrating gun vibrates against the sand shell outside the casting, for the casting, it needs to be vibrated on the vibrating bar. In the process of vibrating the casting, move the vibrating rod to each surface of the casting, vibrate to break the sand shell, and separate the sand shell from the casting, avoid contact between the vibrating rod and one surface of the casting and vibrate to separate the sand shell, so that one part of the casting The surface is always vibrated, which is easy to cause damage to the casting. When vibrating each surface of the casting, the casting needs to be turned, which increases the complexity of the operation.
