Description

Technical Field

[0001] The utility model relates to the technical field of die-casting equipment, in particular to a novel magnesium alloy speaker die-casting equipment. Background Art

[0002] Magnesium alloy is a lightweight metal with a density of 1.82g / cm 3 It is only 3 / 2 of aluminum alloy, but has higher strength and rigidity. This allows magnesium alloy die-castings to reduce overall weight while maintaining strength, and is suitable for applications that require light weight but structural strength. Although magnesium alloys have a low density, they have relatively high strength and rigidity, excellent impact resistance and vibration resistance, and can still maintain good mechanical properties at high temperatures. Magnesium alloys are widely used, and the bracket of magnesium alloy speakers is die-cast with magnesium alloy materials, so it can greatly increase the service life of the speaker and is widely promoted and used.

[0003] As is known, the speakers in the prior art are usually die-cast, and after the workpiece is formed, an ejection mechanism is usually used to eject the workpiece located inside the mold. During the mold opening process, a driving member is usually provided to drive the mold to open and close. Therefore, after the workpiece is cooled and formed, the driving member is first used to drive the mold to open. When the mold slides to a certain position, the ejection mechanism is used to eject the formed workpiece. In this process, it is necessary to wait until the mold opens to a predetermined position before the ejection mechanism can be used to eject the workpiece, which affects the work efficiency to a certain extent. At the same time, the additional provision of a driving source to drive the ejection mechanism to perform the ejection operation will lead to an increase in production costs. Utility Model Content
