Semi-solid state magnesium alloy high-pressure injection molding machine

Abstract

The invention belongs to the technical field of forming machining and relates to a semi-solid state magnesium alloy high-pressure injection molding machine which is composed of an oil pressure propulsion device, a jet nozzle, a charging barrel, a connecting barrel, a screw rod, a non-return ring, a driving servo motor, a stock bin, a heating device and a cooling device, wherein the oil pressure propulsion device comprises a box body, a propulsion bearing and a partition board; the propulsion bearing horizontally penetrates through the box body; the partition board is fixedly mounted on the outer ring of the propulsion bearing in a sleeving manner and divides the interior of the box body into two closed spaces; two oil transportation openings are formed in the box body; the openings of thebox body are positioned in the cavities of the two closed spaces separately; the box body is fixedly connected with one side of the connecting barrel; the charging barrel, the connecting barrel and the oil pressure propulsion device are fixed on a base; and the driving servo motor is fixed on the slidable base. The semi-solid state magnesium alloy high-pressure injection molding machine is low inenergy consumption and fast in forming, can be used for machining a complicated workpiece and is suitable for being widely popularized and applied in the machining field of magnesium alloy. A formed product is smoother in surface, higher in size precision and more stable.

Description

Technical field [0001] The invention belongs to the technical field of forming and processing, and relates to a semi-solid magnesium alloy high-pressure injection molding machine. Background technique [0002] Magnesium alloy is a low-density alloy. Compared with other pure metal materials or alloy materials, and even compared to aluminum alloys, magnesium alloys are lighter in weight. Therefore, the use of magnesium alloy materials to process products is more in line with today's society The requirements for lightweight products have made magnesium alloy products the mainstream material for processing auto parts, military products, and daily necessities. The traditional magnesium alloy molding is a die-cast molding method, which has a slow molding speed and low processing efficiency. At the same time, the product is also prone to defects such as holes, and the quality is difficult to guarantee. Although there are currently injection molding devices for semi-solid magnesium allo...

Problems solved by technology

The traditional magnesium alloy molding is die-casting molding, which has slow molding speed and low processing efficiency. At the same time, the product is prone to defects such as holes, and the quality is difficult to guarantee.

Although there are injection molding devices for semi-solid magnesium alloys developed based on plastic extrusion and injection molding processes, the processed products still have defects such as poor dimensional accuracy, insufficient surface smoothness, and inability to form complex workpieces, which limits the development of magnesium alloys.
