Abstract

The invention discloses a component of casting equipment, and particularly relates to a nozzle device. The nozzle device comprises a nozzle body, and a nozzle opening is formed in the front end of the nozzle body; two nozzle units are arranged in the nozzle opening, each nozzle unit is provided with an eccentric through hole, and the outer diameter of each nozzle unit is consistent with the inner diameter of the nozzle opening; the two nozzle units are spliced together in the front-back direction, and the eccentric through holes in the two nozzle units are identical in hole diameter and partially communicated. According to the nozzle device, the technical defect that a nozzle opening is prone to being blocked in the prior art is overcome, and the nozzle device is not prone to being blocked.

Description

technical field [0001] The invention relates to a casting equipment component, in particular to a nozzle device. Background technique [0002] The existing casting molding process is to pour the molten metal in the molten state into the forming mold through the casting equipment, and then wait for the molten metal to cool and form. [0003] Such as Figure 4 As shown, in the existing casting equipment, a nozzle device 11 is docked with the injection port 15 of the forming mold 4 to realize the drainage of the molten metal 13 . However, the molten metal flowing out during the drainage process is easily splashed and adhered to the nozzle opening of the nozzle device. When the adhered molten metal cools down, it will block the nozzle opening and seriously affect the next casting operation. It may even cause casting failure. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a nozzle device that can avoid clogging of ...
