Abstract

The invention discloses a mold vacuum suction device, which comprises a movable mold plate provided with a movable mold core; a fixed mold plate provided with a fixed mold core, and the movable mold core and the fixed mold core are matched to form a cavity; and vacuum suction pieces comprising a first vacuum suction piece embedded in the fixed mold plate and a second vacuum suction piece embeddedin the movable mold plate. When the movable mold plate and the fixed mold plate are matched, the first vacuum suction piece and the second vacuum suction piece are matched to form an air flow channel,and the air flow channel is communicated with the cavity to discharge air in the cavity to form a vacuum state. The mold vacuum suction device disclosed by the invention is capable of sucking a largeamount of air out of the mold cavity to form a vacuum state by arranging the vacuum suction pieces, so that the bubbling phenomenon is reduced in the product manufacturing process, and the service life of products is prolonged.

Description

technical field [0001] The invention relates to the field of molds, in particular to a vacuum suction device for molds. Background technique [0002] Die casting is a metal casting process, which is characterized by applying high pressure to the molten metal in the cavity of the mold to cast the desired workpiece. [0003] In the field of die-casting, it is well known to adopt mold vacuum devices of different structures to realize a vacuum state in the mold cavity. In the process of researching and realizing the vacuum state of the mold cavity, the inventor found that the mold vacuum device in the prior art has at least the following problems: [0004] First of all, in the process of high-pressure casting with molten metal, there is a large amount of gas in the mold cavity, which will lead to a high gas content in the product after the molten metal is cast, causing bubbling in the product and affecting the quality of the product. mechanical properties. [0005] In view of...
