Problems solved by technology

If these are not cleaned up, they will fall into the shell cavity when the shell is roasted and poured, and remain in the casting to form sand holes, which will cause a lot of trouble for the finishing and grinding of the casting, and will bring great damage to the finishing of the casting. Hidden danger
If the sand falls on the finishing surface, it will seriously affect the sealing of the casting and cause the casting to be scrapped

Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, the device of the present invention for cleaning the sprue cup of a precision casting mold includes a cart 1, a water tank 2, and a grinding wheel 3. The water tank 2 is fixed on the cart 1. The bottom of the water tank 2 is fixed with two cross-arranged steel baffles 4, the two grinding wheel discs 3 are respectively clamped on the two opposite corners of the water tank 2, and they are waterproofed and bonded. Paste the grinding wheel disc 3 on the bottom of the water tank. The two grinding wheel discs 3 are equal in size, the sum of the diameters of the two grinding wheel discs 3 is equal to the length of the water tank 2, and the sum of the diameters of the two grinding wheel discs 3 is greater than the width of the water tank 2. The water tank 2 contains an appropriate amount of clean water, and the water level in the water tank 2 is higher than the upper surface of the grinding wheel 3 by 30-40mm. A control valve 5 is inst...

Abstract

The invention discloses a device for cleaning a pouring cup of an investment casting mould shell. The device comprises a trolley, a water tank and abrasive discs, wherein the water tank is fixedly arranged on the trolley; clear water is contained in the water tank; two baffle plates which are arranged in a crossed mode are arranged on the bottom of the water tank; the two abrasive discs are separately blocked on two opposite corners in the water tank, and are pasted on the bottom of the water tank through a waterproof binder; and a water drainage control valve is mounted on the bottom of the water tank. The device for cleaning the pouring cup of the investment casting mould shell is simple in structure, is low in cost, is convenient to operate, can effectively clear the pouring cup of the mould shell to be clean and orderly, and avoids the casting defect due to the fact that impurities of the pouring cup of the mould shell drop into a mould cavity of a cast piece.

Description

Technical field [0001] The invention relates to the field of investment precision casting, in particular to a clean processing device for a precision casting shell sprue cup. Background technique [0002] It is impossible to completely repair and tidy the shell sprue cup during the coating shell making operation. After dewaxing, there will be a small amount of slurry flash, extra shell protrusions and loose sand on the top surface of the shell sprue cup. . If these are not cleaned up, they will fall into the shell cavity when the shell is roasted and poured, and will remain in the casting to form blisters, which will cause a lot of trouble in the finishing and grinding of the casting, and bring a lot to the finishing of the casting. Hidden dangers. If sand loss occurs on the finished surface, it will seriously affect the sealing of the casting and cause the casting to be scrapped. Summary of the invention [0003] The technical problem to be solved by the present invention is t...
