Die-casting die of cast steel bucket teeth

Abstract

The invention discloses a die-casting die of cast steel bucket teeth. The die-casting die comprises a fixed die base, a fixed die, a movable die, a material cavity, a movable die cavity, a fixed die cavity and an ejection block, wherein the fixed die is fixed to the upper part of the fixed die base, the fixed die cavity is formed in the upper end of the fixed die, a fixed die sand core is fixed to one side of the fixed die cavity, the material cavity is arranged under the fixed die cavity, the ejection block is arranged inside the material cavity, the bottom of the ejection block is connected to one end of an ejection rod, the other end of the ejection rod is connected to a hydraulic cylinder, the movable die is arranged on the fixed die, the movable die cavity symmetric with the fixed die cavity is formed in the bottom end of the movable die, a movable die sand core is arranged on one side of the movable die cavity, the movable die sand core and the fixed die sand core are provided with transverse blind holes, and transverse exhaust holes are formed in the part, located on the outer side of the movable die sand core, of the movable die and in the part, located on the outer side of the fixed die sand core, of the fixed die. The die-casting die of the cast steel bucket teeth has the advantages that the ejection speed is high, the forming period is short, the die-casting efficiency is high and the surface quality of the bucket teeth is guaranteed.

Description

technical field [0001] The invention relates to the field of casting molds for excavator parts, in particular to a die-casting mold for cast steel bucket teeth. Background technique [0002] Excavator is a kind of construction machinery and mining machinery commonly used in excavation and loading operations. Cast steel bucket teeth are an important part of excavators. Die casting is a metal casting process characterized by applying high pressure to molten metal using a mold cavity , due to the high cost of casting equipment and molds, the die-casting process is generally only used to manufacture a large number of products in batches. After the die-casting is completed, the mold is generally ejected by the ejector device, but the existing die-casting mold is slow due to the ejection speed , which affects the die-casting efficiency, and the heat dissipation is slow, the mold molding cycle is long, and the production efficiency is reduced.
