Pneumatic double-station cylinder-free wax injection machine

Abstract

The invention discloses a pneumatic double-station cylinder-free wax injection machine. The pneumatic double-station cylinder-free wax injection machine comprises a machine frame, wax injection devices, wax feeding cylinders, control cabinets, wax storage cylinders and die assemblies, wherein the wax injection devices, the wax feeding cylinders, the control cabinets, the wax storage cylinders and the die assemblies are symmetrically arranged on the top surface of the machine frame; the wax injection devices are driven by air cylinders and are coordinated with hand wheels for fine adjustment so as to realize the movement of the six degrees of freedom; the wax feeding cylinders are driven by hydraulic pressure; the control cabinets are arranged at the tops of the die assemblies; a workbench is arranged on the top surface of the machine frame; the workbench and an operation table are arranged in a coplanar mode; positioning holes with the diameters of 5mm are formed in the surface of the workbench; and each wax feeding cylinder comprises a pipeline connecting part, a limiting plate, wax feeding cylinder fixing rods and a wax feeding cylinder fixing plate. Compared with the prior art, the pneumatic double-station cylinder-free wax injection machine has the advantages that the use response speed is high, double stations can work simultaneously, the service life of the wax feeding cylinders is long, the vibration is small, the three-column type supporting operation space is large, the operation safety is good, and the personal safety of operators can be protected.

Description

Technical field [0001] The invention relates to the field of precision casting equipment, in particular to a wax injection machine with two symmetrical operating stations driven by air pressure. Background technique [0002] Precision casting is also called lost wax casting. Its products are precise, complex, and close to the final shape of the part. It can be used directly without processing or with little processing. Therefore, investment casting is an advanced technology with near net shape, compared with traditional sand molds. The casting process, precision casting, the casting size is more accurate, and the surface finish is better. One of the more commonly used is investment casting, also known as lost wax casting: select suitable investment materials (such as paraffin) to make investment molds; repeat the steps of dipping refractory paint and sprinkling refractory sand on the investment mold, hardening the shell and drying; then Melt the internal investment mold to obtai...

AI Technical Summary

Problems solved by technology

The traditional wax injection machine adopts hydraulic drive, single station, short service life of the wax cylinder, small space for mold operation, and low operation safety, which limit the development of the wax injection machine. Therefore, there is an urgent need for a pneumatic double-station cylinder-free The wax injection machine solves the above problems
