Problems solved by technology

However, the mold clamping mechanism adopts a double toggle mold clamping structure. Due to the influence of machining accuracy, the force on the moving template is uneven, the mechanical parts are easily damaged by the bias load, the stability of the equipment is poor, and the maintenance is inconvenient.
Moreover, the molten metal inlet channel is unreasonable. When the molten metal enters the mold cavity, eddy currents will cause air entrainment. The produced die castings have many impurities inside, and there are scattered small bubbles, making it difficult to produce high-quality die castings. pieces

Abstract

The invention relates to the technical field of casting equipment, and discloses a vertical squeeze casting machine. The machine comprises a mold opening and closing device and an injection device, the mold opening and closing device comprises a rear mold plate, a fixed mold plate, a movable mold plate, an opening and closing assembly and a liquid filling assembly, in the casting process, the opening and closing assembly drives the movable mold plate to conduct mold closing or mold opening, and rapid mold locking is achieved; and in the mold closing state, the liquid filling assembly can conduct pressurization mold locking on the movable mold plate, the opening and closing assembly and the liquid filling assembly are separately controlled, the mold opening and closing time is greatly shortened, and the production efficiency is improved. The injection device comprises a base, an injection assembly and a feeding assembly, the fixed mold plate is provided with a liquid inlet in butt jointwith the injection assembly, and the injection assembly reciprocates between the feeding assembly and the liquid inlet. The feeding assembly independently provides molten metal for the injection assembly, then the injection assembly injects the molten metal into a metal impression to complete casting, the flowing path is short, gas is located on the molten metal, the gas entrapment phenomenon isreduced through injection from bottom to top, and the product quality is improved.

Description

technical field [0001] The invention relates to the technical field of casting equipment, in particular to a vertical squeeze casting machine. Background technique [0002] Squeeze casting (liquid die forging) technology is currently widely used in national defense and military industry, transportation, 3D forming and communication mobile phones and other industries, and has become one of the important technologies in advanced manufacturing technology to realize the formation of complex parts with less cutting and no cutting. The working principle is to directly inject a certain amount of molten metal into the cavity of the metal mold, then close the mold to realize the filling and flow of the molten metal, and undergo high-pressure solidification and a small amount of plastic deformation under the action of mechanical static pressure to obtain blanks or parts. [0003] A traditional casting machine includes a mold clamping mechanism, an injection mechanism, an electric cont...
