Magnesium Alloy Semi-solid Injection Molding Mechanism

Abstract

The invention discloses a magnesium alloy semi-solid injection molding mechanism, which comprises a material cylinder arranged horizontally, a nozzle is arranged on one end surface of the material cylinder, a wear-resistant piston is arranged in the other end of the material cylinder, and a material spraying push block is provided by a second material cylinder. A push block driving mechanism drives and can move back and forth along the axial direction of the barrel. A barrel heating device is provided on the outer periphery of the barrel; a feeding port is provided on the upper side of the barrel, and a mixing and pulping conveying screw is arranged inside the feeding port to feed The outer seal of the feed port is connected to the lower end of a first feed channel; the upper end of the first feed channel is connected to the discharge port of a slanted silo, and the outer periphery of the first feed channel is provided with a feed heating device; The other side of the discharge port is provided with a feed push block, which is driven by the second push block drive mechanism and can push the magnesium ingots placed in the feed bin into the first feed channel. The magnesium alloy semi-solid injection molding mechanism uses magnesium ingots directly as raw materials, does not need to turn the magnesium ingots in advance to form granules, greatly reduces processing costs, and can increase welding capacity to realize the production of large products.

Description

technical field [0001] The invention relates to an injection molding mechanism, in particular to a magnesium alloy semi-solid injection molding mechanism. Background technique [0002] Under the wave of lightweight automobiles and the pursuit of humanization of electronic products, the design of traditional materials is difficult to meet the needs. The solution to the trend is magnesium alloy molded products. The density of magnesium is about 2 / 3 of that of aluminum. In practical applications The lightest of the metals. Magnesium alloy has strong vibration absorption ability, good cutting performance, good metal mold casting performance, and good wear resistance, which are very suitable for manufacturing auto parts. Therefore, under the requirements of quality and environmental protection, it has become a popular choice to use magnesium alloys to make car dashboard frames, seats, steering column components, steering wheel cores, gearbox casings, engine mounts, etc., as well...

Problems solved by technology

[0004] However, the existing magnesium alloy injection molding mechanism must use pellets, that is, magnesium ingots must first be turned into pellets before they can be put into the injection molding mechanism, which not only increases the process steps, but also has high processing costs; secondly, the existing injection molding The barrel melting capacity of the mechanism is restricted by the shape of the barrel, making it impossible to manufacture large products
