Mold core with ultrasonic vibration device

Abstract

The invention discloses a mold core with an ultrasonic vibration device. The mold core is characterized in that the mold core comprises a mold core mechanism, an exhaust mechanism, a transducer cooling mechanism and a channel mechanism; according to the mold core mechanism, the mold core is provided with a mold core hole, a mold core head and a mold core rod are arranged in the mold core hole, hole channels for measuring temperature wire are arranged in the mold core head and the mold core rod, thermocouples for measuring temperature is arranged in the top end of the hole channel, the exhaustmechanism is arranged on the opposite side of the mold core head and on the outer surface of the mold core rod, the transducer cooling mechanism is arranged on the lower part of the mold core rod; andan ultrasonic transducer is arranged on the lower end of the mold core rod. According to the mold core with the ultrasonic vibration device, the ultrasonic vibration device fixed in the lower mold ofa metal mold is adopted so that aluminum liquid being injected is subjected ultrasonic vibration, so that the filling and forming are accelerated, the orderly exhaust speed is accelerated at the sametime, the forming quality of products is improved, the mold core is cooled automatically and rapidly, the air cooling process of manual operation is omitted, and the product quality and output are improved.

Description

technical field [0001] The application relates to a mold for gravity casting of a metal mold in the field of aluminum alloy casting, in particular to a mold core with an ultrasonic vibration device used in the lower mold of the metal mold. Background technique [0002] In order to keep up with the pace of energy saving and emission reduction, the popularity of superchargers in fuel vehicles has been developing and is highly competitive; the aluminum alloy compressor casing at one end of the supercharger is produced in the production process of metal mold gravity casting And it is easy to produce pores, which seriously affects the product qualification rate; the traditional method of degassing the lower mold today still only relies on setting an exhaust plug on the top of the core of the lower mold to exhaust, and its position is just below the gate, which is often compared Blockage occurs when the high-temperature aluminum liquid is poured, resulting in poor exhaust and air ...

[0002] In order to keep up with the pace of energy saving and emission reduction, the popularity of superchargers in fuel vehicles has been developing and is highly competitive; the aluminum alloy compressor casing at one end of the supercharger is produced in the production process of metal mold gravity casting And it is easy to produce pores, which seriously affects the product qualification rate; the traditional method of degassing the lower mold today still only relies on setting an exhaust plug on the top of the core of the lower mold to exhaust, and its position is just below the gate, which is often compared Blockage occurs when the high-temperature aluminum liquid is poured, resulting in poor exhaust and air bubbles and pinholes remaining in the product, and it is difficult for the operator to detect it at the time. After the detection is found, the only way to do it is to remove the mold, remove the mold, and replace the exhaust plug. production, resulting in increased mold maintenance workload, decreased production capacity and pass rate; in this industry, although ultrasonic vibration devices are used to degas the aluminum liquid or install it on the upper mold and retract it after treatment, its degassing effect Small, the effect on crystallization is not obvious, and the structure is complex
