Vertical compression type horizontal die-casting machine and die-casting method thereof

Abstract

The invention discloses a vertical compression type horizontal die-casting machine and a die-casting method thereof and belongs to the field of metal die-casting. The vertical compression type horizontal die-casting machine comprises a supporting mechanism, an injection mechanism and a die locking mechanism, wherein the die locking mechanism comprises a movable die base, a fixed mounting plate, head plates arranged on the fixed mounting plates, tail plates arranged on the movable die base, pull rods hinged between the head plates and the tail plates and crankshaft rods connected with the pullrods and the head plates. When the movable die base instantly retreats and the included angle between the two pull rods is approximately horizontal, the vertical compression type horizontal die-casting machine transmits original backward push force of the movable die base to the T-shaped crankshaft rods, torque is greatly reduced, and the rebound effect is further reduced further through pressurestabilization of a gas resistor. A one-way valve is arranged at a feed port, and the vertical compression type horizontal die-casting machine conducts accurate feeding to prevent the situation of non-uniformity of the solution injection amount. The problems that a movable die base is likely to instantly retreat and the size precision of die cast parts is affected in the die-casting process of an existing die-casting machine are solved.

Description

technical field [0001] The invention belongs to the field of metal die-casting, in particular to a direct-pressure horizontal die-casting machine and a die-casting method thereof. Background technique [0002] Die casting refers to the method of filling liquid or semi-liquid metal into the metal mold cavity at a high speed under high pressure, and forming and solidifying under pressure to obtain castings. It is the fastest production speed among all casting methods. a method of It can produce metal parts with complex appearance, clear outline, thin wall and deep cavity. Now the die-casting process is widely used in industrial applications, and has become a popular choice in many fields such as automobiles and motorcycles, aerospace, electrical instruments, communication equipment, medical machinery, and daily necessities. Important or even necessary means of production of components. [0003] Among them, in the mold clamping and injection process, due to the expansion of t...
