井蓋模具經過****使用過后就會產生各方面的磨損,所以要想延長壽命的話就要定時維護模具,主要需要:主要工作零件的材料的問題,選材不當,不耐磨;模具鋼未精煉,具有大量的冶煉缺陷。
After long-term use, the well cover mold will produce various aspects of wear, so if you want to prolong the service life, it is necessary to regularly maintain the mold, the main needs are: material problems of main working parts, improper material selection, non wear resistance; mold steel is not refined, with a large number of smelting defects.

凸凹模,鍛坯改鍛工藝不完善,遺存有熱處理隱患.結構設計問題.細長凸模沒有設計加固裝置,出料口不暢現堆集,卸料力過大使凸模承受力變載荷加劇等。
There are some problems in the structure design, such as the lack of reinforcement device for the slender punch, the poor discharge port, and the increase of discharge force, etc.

制模工藝不完善,主要表現在凸、凹模鍛坯內在質量差,熱處理技術及工藝有問題,造成凸、凹模淬不透,有軟點及硬度不均.有時產生微裂紋、甚至開裂。
The imperfection of die making process is mainly manifested in the poor internal quality of punch and concave die forging blanks, problems in heat treatment technology and process, resulting in hardenability of punch and die, uneven soft spots and hardness, and sometimes microcracks or even cracks.

井蓋模具內冷卻,減少用噴涂解決模具溫度平衡,減少噴涂時間,減少鑄件在模具上的冷卻時間,提高生產節奏,提高壓鑄生產效率;另一方面,重點關注模具拆裝的快速,以及減少模具維修維護,更換易損件的時間。
The inner cooling of well cover mould can reduce the use of spraying to solve the mold temperature balance, reduce the spraying time, reduce the cooling time of casting on the mold, improve the production rhythm and improve the production efficiency of die casting; on the other hand, focus on the rapid disassembly and assembly of the mold, and reduce the time for mold maintenance and replacement of vulnerable parts.
