Medium-temperature and high-pressure wax preparing device

Abstract

The invention discloses a medium-temperature and high-pressure wax preparing device. The medium-temperature and high-pressure wax preparing device comprises a primary wax emulsifying system, a primarypressurizing system, a wax emulsifying system, a secondary pressurizing system, a heat preservation medium II preparing system, a heat preservation sleeve, a wax absorbing pipe, a heat preservation medium II, a low-pressure wax outlet pipe and a paste wax outlet pipe. The module dividing and system dividing design is adopted in the provided medium-temperature and high-pressure wax preparing device, the medium-temperature and high-pressure wax preparing device comprises the primary wax emulsifying system, the primary pressurizing system, the wax emulsifying system and the secondary pressurizing system, through heating and melting of the primary wax emulsifying system, primary pressurizing of the primary pressurizing system and the primary pressurizing and melting state of the wax emulsifying system, and the medium-temperature and high-pressure wax is finally obtained through secondary pressurizing. The provided machine can manufacture a large amount of medium-temperature and high-pressure wax for a die, and the production efficiency is improved. A heat preservation device is adopted in the disclosed machine in the whole preparing process, unnecessary heat losses are avoided, meanwhile, the machine shutdown cleaning frequency is reduced, the production efficiency is improved, and the service life of the machine is prolonged.

Description

technical field [0001] The invention relates to a wax preparation device, in particular to a medium temperature and high pressure wax preparation device. Background technique [0002] Wax materials for investment casting are divided into three types: low-temperature wax materials, medium-temperature wax materials, and high-temperature wax materials; the physical properties of medium-temperature wax materials: mainly rosin-wax-based mold materials and filled mold materials, with a melting point of 70-100 degrees Celsius , mainly used for castings with high requirements on size and surface. Generally, stainless steel and medium-high alloy steel products use mold materials, which are dewaxed by steam or microwave, and the wax materials can be reused.

Problems solved by technology

[0003] Although there are quite a lot of equipment for preparing medium temperature wax, the systems of most equipment are relatively chaotic, and the heat loss of the system is relatively serious, which is very unfavorable for energy saving. The blockage of the pipes caused the machine to be shut down for cleaning, which was not conducive to continuous production. At the same time, the medium temperature wax of many equipment could not reach the corresponding temperature, which had a great impact on the investment casting process.
