Description

Investment casting sand shell cladding device Technical Field The utility model relates to the technical field of investment casting, in particular to an investment casting sand shell cladding device. Background Casting is one of the hot working processes of metals, and many parts in the industry today need to be worked by casting. The investment casting is to manufacture a shell mould firstly, the shell mould is generally manufactured by using wax to manufacture a wax mould of a part to be cast, the wax mould is put into sand or slurry mainly made of refractory materials such as quartz, corundum and the like, the sand or slurry is wrapped outside the wax mould to form the shell mould after drying, then the wax mould in the shell mould is melted, wax liquid flows out of the shell mould, at the moment, a casting cavity which is suitable for the shape of the part is formed in the shell mould, and molten iron is led into the cavity of the shell mould and then cooled, thus the casting process is completed. Typical sanding devices are prone to incomplete coverage of the complex casting wax pattern, resulting in incomplete shell mold. Disclosure of utility model Aiming at the defects existing in the prior art, the utility model aims to provide an investment casting sand shell cladding device which solves the existing pain point in the field. The technical aim of the utility model is realized by the following technical scheme: The utility model provides an investment casting sand shell cladding device, includes the packing box, the packing box bottom is provided with the platform, can fix on the platform and place the limit cylinder, with the unsettled putting into of wax matrix from the top in the limit cylinder. Further stated, the upper edge of the stuffing box is hinged with a sand blasting gun. Further, the metering cylinders are provided in different sizes, and different sizes of metering cylinders are used for different sizes of wax patterns. Further stated, the sand blasting gun is communicated with the storage box, and is connected with an air pipe, the air pipe is connected with an air source, and the storage box is filled with sand. Further stated, the conveying tower is fixedly installed outside the stuffing box, the discharging port is arranged at the bottom of the stuffing box, the feeding channel is arranged at the bottom of the conveying tower, the bottom surface of the feeding channel is inclined, the feeding channel is connected with the discharging port and communicated with the stuffing box, the spiral conveying shaft is rotationally installed in the conveying tower, the conveying motor is fixedly installed at the top of the conveying tower and connected with the spiral conveying shaft, the storage box is fixedly installed at the top of the conveying tower, and an opening is formed in the top of the conveying tower and communicated with the storage box. Further stated, the upper edge of the discharge opening is hinged with a separation door plate. Further, a door stop is vertically and slidably arranged at the top of the feeding channel, the door stop can stop the separation door plate from being opened, and an air cylinder is fixedly arranged on the side surface of the stuffing box, is connected with the door stop and can drive the door stop to move up and down. In summary, compared with the prior art, the utility model has the beneficial effects that after the wax mould is suspended in the air and placed in the limiting cylinder with the selected size, sand is injected into the limiting cylinder through the sand blasting gun, so that the sand buries the wax mould, the sand completely wraps the wax mould, the limiting cylinder is taken out after the shell mould is formed, the unattached sand is scattered into the stuffing box, and the unattached sand can enter the feeding channel through the discharge port, and then is sent into the storage box through the spiral conveying shaft for storage and repeated use.
