Multifunctional pouring cup and processing method thereof

Abstract

The invention provides a multifunctional pouring cup and a machining method thereof, and relates to the field of investment casting, the pouring cup is of a bowl-shaped structure, a top cover is arranged at a cup opening, a cylindrical channel extending downwards is formed in the bottom of the pouring cup, an upper step and a lower step are arranged in the channel, and a filter screen is arranged between the upper step and the lower step; a sprue stick is welded to the bottom of the channel, the inner wall of the sprue cup is an arch-shaped arc face, double-spiral protruding ribs are arranged on the inner wall of the sprue cup, grooves are formed between the double-spiral protruding ribs, and exhaust ribs are symmetrically arranged on the two sides of the outer wall of the sprue cup. The phenomenon that the shell at the pouring cup cracks under long-time high-temperature impact can be solved, and the problem that the whole model cannot be molded by casting due to the cracking of the shell is avoided. Meanwhile, the convex ribs of the double-helix structure can enhance the exhausting and slag accretion effects, and thin slag in molten aluminum is prevented from entering the module; the symmetrically-designed exhaust rib structure can quickly exhaust gas in the module, and the defect that the gas stays in the module to form air holes in the casting is avoided.

Description

technical field [0001] The invention relates to the field of investment casting, in particular to a multifunctional pouring cup and a processing method thereof. Background technique [0002] Aluminum alloy is an ideal lightweight material for automobiles, which can improve vehicle safety and fuel economy while reducing carbon emissions in the entire life cycle of automobiles. It has been widely used in many industries, especially in recent years, the production scale and output of aluminum alloy investment castings have increased rapidly, and a large number of production enterprises have appeared. [0003] The aluminum alloy investment casting process is to make a fusible material into a pattern, weld multiple patterns on the gate rod, then coat several layers of refractory material on the pattern surface to make a mold shell, and then melt the pattern out of the mold shell, thereby A casting plan without a parting surface is obtained, and the aluminum alloy solution can be...
