AI Technical Summary
When casting and making beryllium bronze models, water ripples are easily generated at the pouring mouth, resulting in depression on the surface of the model and affecting flatness.
A casting molding equipment is designed, and a circular groove is opened at the bottom of the pouring port between the lower mold and the upper mold. The opening of the pouring cavity is inclined to form an integrated pouring cavity to prevent water ripples from occurring through the circular groove buffering.
Disc-shaped bulges appear on the top of the beryllium bronze casting after cooling, and water ripples appear on the top of the bulges. The bulges can be polished during subsequent processing to prevent water ripples from affecting the flatness of the outer surface of the model.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting and molding, in particular to a casting and molding device. Background Art
[0002] Beryllium bronze is a kind of Wuxi bronze with beryllium as the main alloying element. After quenching and aging treatment, the ultimate strength can reach 1250-1500MPa, which is close to the level of medium-strength steel. It has good plasticity in the quenched state and can be processed into various semi-finished products. Beryllium bronze has high hardness, elastic limit, fatigue limit and wear resistance, as well as good corrosion resistance, thermal conductivity and electrical conductivity. It does not produce sparks when impacted and is widely used as important elastic components, wear-resistant parts and explosion-proof tools.
[0003] At present, when the beryllium bronze model is made by casting, the upper and lower casting molds need to be engaged with each other, and then the molten beryllium bronze is poured into the internal molding area. After cooling, the mold is opened to obtain the beryllium bronze model. However, water ripples are easily generated at the pouring port during condensation. When the water ripples are deeply concave, it will cause depressions on the surface of the model after subsequent polishing, affecting the flatness of the outer surface of the model.
