Efficient cooling die-casting machine melting cup

Abstract

The invention discloses an efficient cooling die-casting machine melting cup. The melting cup comprises a cup body, a flange edge and an alloy liquid inlet and further comprises a spiral cooling pipe,wherein the cup body is in a hollow column shape, an injection hole is formed in the center of the cup body, the alloy liquid inlet is formed in the side wall of the tail end of the cup body, communicates with the injection hole and is used for injecting alloy liquid, a plunger pushes alloy liquid to be injected into a die-casting die, the annular step-shaped flange edge is arranged on the outerwall of the front end of the cup body and makes contact with a die for positioning, in order to adapt to die-casting machines of different tonnages, the outer diameter of a step at the front end of the cup body is smaller than that of a step at the rear end of the cup body, and the front end of the cup body is sleeved with a conversion sleeve; and the spiral cooling pipe is connected to the outercylindrical face of the cup body in a sleeving mode, the head and the tail of the spiral cooling pipe are connected with a liquid inlet pipe and a liquid outlet pipe respectively, circulating coolingliquid is connected into the liquid inlet pipe and the liquid outlet pipe through connectors, and the front end of the spiral cooling pipe is attached to the flange edge. The melting cup is easy to machine and assemble, the whole cup body can be evenly cooled, and the service life of the melting cup is prolonged.

Description

technical field [0001] The invention belongs to the field of die casting, and in particular relates to an efficient cooling melting cup of a die casting machine. Background technique [0002] In the production of auto parts, the slurry is directly poured into the melting cup for die-casting. When the die-casting machine is in die-casting production, the melting cup is fixed on the front plate of the die-casting machine, and the mold is positioned and installed through the sprue sleeve and the melting cup. The bore is connected with the cavity of the mold, and the alloy liquid enters the inner bore of the melting cup through the injection port of the melting cup, and the alloy liquid is filled into the mold through the inner bore of the sprue sleeve through the movement of the plunger in the inner bore of the melting cup. In the cavity, a casting product of a certain shape is produced. Since the temperature of the alloy liquid is about 660°C, the high temperature puts forwar...

Problems solved by technology

[0003] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is that the long-term high-temperature working environment leads to a reduction in the service life of the melting cup, and the processing and assembly of the existing cooling hole group is complicated, and only half of the cup body is cooled. The cooling effect is uneven, which can easily lead to the deformation of the cup body due to temperature difference
