Description

TECHNICAL FIELD

[0001] The utility model relates to die casting mould technical field, concretely is a kind of end cover die casting device of convenient replacement mould. BACKGROUND

[0002] In the field of end cover die casting, the efficient replacement and stable operation of die casting mould are crucial. Although the current die casting technology is constantly developing, there are still significant pain points in the mould replacement process.

[0003] The mould installation in the prior art adopts bolt fastening mode. In actual production, when facing frequent mould replacement requirements, workers need to use wrenches and other tools to loosen multiple bolts one by one, and the whole process is tedious and time-consuming. The single mould replacement time often lasts for several hours, affecting the production efficiency. At the same time, this traditional installation method cannot guarantee the accuracy of mould installation. After multiple disassembly and installation, the mould is prone to slight deviation, which makes it difficult to control the size precision of the die-cast end cover.

[0004] For example, some conventional die casting equipment only relies on simple slot cooperation for mould installation and positioning, lacking effective guiding and fastening measures. During the die casting process, the mould is easily displaced due to the impact of high-temperature and high-pressure metal liquid and the vibration of the equipment itself.

[0005] In summary, the existing end cover die casting device has many shortcomings in terms of mould replacement convenience, installation accuracy and mould handling, and an innovative solution is needed to improve the overall efficiency and quality of end cover die casting production. In view of this, we propose a kind of end cover die casting device convenient for replacing mould. UTILITY MODEL CONTENT
