Description

Technical Field

[0001] The utility model belongs to the technical field of wax injection technology for empty tube castings, and particularly relates to an empty tube wax injection machine. Background Art

[0002] The wax injection machine for hollow tube castings is an automated casting device primarily used to precisely inject heated liquid wax into hollow tube casting molds to form the desired wax pattern. These wax patterns are then processed through processes such as sintering to become the final metal casting. Solid wax pellets are added to the wax injection machine's hopper, where a heating device melts the wax pellets into liquid wax. Under set temperature, pressure, and time parameters, the liquid wax is injected into the hollow tube casting mold via a syringe or pressure pump. The wax cools and solidifies in the mold, forming a wax pattern in the opposite shape of the casting. Once the wax pattern has completely cooled, it is removed from the mold for subsequent sintering and other processing steps.

[0003] Wax injection machines for air tube castings are widely used in the manufacturing of castings that require high precision and complex shapes, such as aerospace, machinery manufacturing, automotive parts, jewelry, etc. However, the wax injection machines for air tube castings on the market can only perform casting operations on a single workpiece when in use. This wax injection process obviously does not have high efficiency. In addition, manual intervention is required during the wax injection process, which reduces the degree of automation. The surface of the casting cannot be evenly cooled after wax injection, which reduces the molding efficiency and thus reduces production efficiency. Utility Model Content
