Description

Technical Field

[0001] The invention relates to the technical field of integrated die-casting, and in particular to an integrated die-casting molding device for aluminum profiles. Background Art

[0002] The die-casting machine is a series of industrial casting machines that hydraulically inject molten metal into the mold under pressure to cool and form, and obtain solid metal castings after the mold is opened. It can work in an uninterrupted cycle. In the field of aluminum profile die-casting, traditional die-casting equipment usually sets a separate airway inside the cavity for vacuum operation. However, this design has many disadvantages. During the grouting process, aluminum liquid easily flows into the airway, causing the airway to be blocked, affecting the vacuum effect, and then making the gas in the cavity difficult to discharge, increasing the possibility of flash on the product. Moreover, during the demolding stage, due to the unreasonable layout of the airway structure in the cavity, the problem of adhesion between the profile and the cavity often occurs, which not only reduces the quality and production efficiency of the product, but also leads to an increase in the amount of nozzle material generated, increasing production costs.
