Metal mold casting and molding device based on ultrasonic waves

Abstract

A metal mold casting and molding device based on ultrasonic waves comprises an ultrasonic wave generating system and a metal mold casting mould system, wherein the metal mold casting mould system is the traditional metal mold casting and molding device; an ultrasonic generator of the ultrasonic wave generating system is connected with an ultrasonic receiver arranged on the metal mold casting mold system through an ultrasonic wave amplitude-change pole; the amplitude-change pole is connected with the ultrasonic generator through an ultrasonic wave transducer; a central processing unit is respectively connected with an ultrasonic wave generator and an A / D (alternating current / direct current) converter; and the A / D converter is connected with the metal mold casting mould system through a temperature sensor. By the metal mold casting and molding device based on the ultrasonic waves, castings with accurate shapes, high precision, small surface roughness value, fine crystalline grains and high mechanical property are obtained on the premise that requirements on metal mold casting and molding are met. The molding rate of the castings is improved effectively. The metal mold casting and molding device is low in noise, easy to operate and control and suitable for casting and molding of most of metal molds.

Description

technical field [0001] The invention relates to the technical field of metal mold casting, in particular to an ultrasonic-based metal mold casting device. Background technique [0002] Metal mold casting, also known as hard mold casting, is a casting method in which liquid metal is poured into metal molds to obtain castings. The casting mold is formed by casting through a metal mold, and the mold can be used repeatedly many times. Castings produced by metal molds have higher mechanical properties, precision and surface finish than sand castings, and have higher production efficiency. However, the castings currently produced by metal mold casting are still limited in terms of weight and shape. They can only be castings with simple shapes and light weight; and the wall thickness is also limited, and smaller castings cannot be cast. Even in metal mold casting, the working temperature of the mold, the pouring temperature and speed of the alloy, the time the casting stays in th...
