Description

A shaping jig for die-casting raw materials of communication base stations

Technical Field

The utility model relates to the technical field of die-casting, and in particular to a shaping jig for die-casting raw materials of communication base stations.

Background Art

In the prior art, die-cast steel sheets usually deform during the forming and ejection process, while die-cast flat steel sheets are widely used in modern production, such as in magnesium-aluminum alloy middle frame products for mobile phones. Since the flatness of the flat assembly surface of the mobile phone magnesium-aluminum alloy middle frame of die-cast flat steel sheets is required to be high, it is usually necessary to shape the die-cast steel sheets after die-casting and ejection. The conventional shaping method is to flatten them with upper and lower dies;

A Chinese patent discloses a die-cast steel sheet heat shaping jig (authorization announcement number CN 205463711 U). The patented technology includes an upper die and a lower die that are arranged correspondingly. The bottom of the upper die is provided with an arc-shaped protrusion, and the top of the lower die is provided with an arc-shaped groove corresponding to the arc-shaped protrusion. A number of positioning pins are protruding from the arc-shaped groove. Avoidance holes are provided on the arc-shaped protrusion corresponding to the positioning pins. The utility model has a simple and reasonable structure and an ingenious design. Through the cooperation of the arc-shaped protrusion and the arc-shaped groove, the die-cast steel sheet can be well calibrated. The deformation recovery after calibration is low, and the yield rate of the die-cast steel sheet after calibration is high, which can meet the needs of use.

However, the jig cannot automatically eject the die-cast module and requires manual operation, which increases production time and reduces efficiency. Therefore, those skilled in the art provide a shaping jig for die-casting raw materials of communication base stations to solve the problems raised in the above background technology.
