Abstract

The invention discloses a device and method for moulding and forming a micro-turbine, and relates to a device and method for forming a micro-turbine, for solving the problems in the prior art having low material utilization rate, low processing efficiency, high processing cost and unsuitable batch production in the event of manufacturing the micro-turbine. The device comprises a male mould, a female mould, a female mould holder, an ejector rod, an electrically heated component, a temperature sensor, a temperature control meter and a first screw. A groove is arranged in the middle of the upperhead face of the female mould holder. The female mould is in the groove of the female mould holder. The female mould and the female mould holder are detachably connected. A formed groove is arranged in the middle of the upper head face of the female mould. A blade groove is arranged on the lower head face of the formed groove. The male mould is in the formed groove of the female mould. The femalemould holder is in the electrically heated component. The electrically heated component and the female mould holder are glidingly connected. A probe of the temperature sensor is contacted with the female mould. A signal output end of the temperature sensor is connected with a signal input end of the temperature control meter. A signal output end of the temperature control meter is connected with the electrically heated component. The device is used for forming the micro-turbine.

Description

technical field [0001] The invention relates to a micro-turbine shaping device and method. Background technique [0002] With the characteristics of small size, light weight, small inertia, low energy consumption and high integration, micro-machines have broad application prospects driven by micro-electro-mechanical systems and micro-system technologies. The micro impeller pump is a micro fluid machine with fluid as the medium, and has broad application prospects in medical treatment, aerospace and modern industry. The principle of the micro impeller pump is to continuously transport liquid through the rotation of the micro impeller, which has the advantages of high efficiency, stable performance and long life. Its key component is the micro impeller, which has an important impact on the efficiency, life and stability of the pump. Therefore, it is of great significance to process high-quality, low-cost micro-impeller parts. At present, the micro-turbine mainly adopts MEMS...
