Description

Technical Field

[0001] This utility model relates to the field of valve wax pattern production technology, and in particular to a valve wax pattern injection molding device. Background Technology

[0002] Investment casting, also known as lost-wax casting, includes processes such as wax pressing, wax trimming, tree assembly, slurry application, wax melting, pouring molten metal, and post-processing. Lost-wax casting involves creating a wax model of the part to be cast, then coating the wax model with clay slurry to form a clay model. After the clay model dries, it is placed in hot water to melt the inner wax model. The melted clay model is then removed and fired to form a ceramic mold. Once fired, a pouring gate is typically left during the clay model making process. Molten metal is then poured through the gate, and after cooling, the desired part is formed.

[0003] In the current valve manufacturing process, casting wax is generally melted and cast into the shape of the valve, and then trimmed. The outer surface of the wax pattern valve mold is then coated, sanded, and dried in three repeated steps to form a shell. After heating and dewaxing, the valve shell is directly obtained. The obtained valve shell is then fired and poured. After cooling, it is vibrated to remove the shell and obtain the valve component. The wax obtained after heating and dewaxing can be recycled and reused. In the preparation of the wax pattern valve mold, molten wax is injected into the forming mold, and after cooling, it is removed to obtain the wax pattern. However, existing injection molding processes involve manually pouring wax into the forming mold. The wax temperature is high, which can easily cause safety hazards. Moreover, the wax is prone to solidification, which not only wastes manpower and resources but also results in low work efficiency. Summary of the Invention
