井盖模具延长寿命需要哪些细节
发布人:管理员   发布时间:2020-11-20

井盖模具经过****使用过后就会产生各方面的磨损,所以要想延长寿命的话就要定时维护模具,主要需要:主要工作零件的材料的问题,选材不当,不耐磨;模具钢未精炼,具有大量的冶炼缺陷。
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,锻坯改锻工艺不完善,遗存有热处理隐患.结构设计问题.细长凸模没有设计加固装置,出料口不畅现堆集,卸料力过大使凸模承受力变载荷加剧等。
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.

      

制模工艺不完善,主要表现在凸、凹模锻坯内在质量差,热处理技术及工艺有问题,造成凸、凹模淬不透,有软点及硬度不均.有时产生微裂纹、甚至开裂。
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.

井盖模具内冷却,减少用喷涂解决模具温度平衡,减少喷涂时间,减少铸件在模具上的冷却时间,提高生产节奏,提高压铸生产效率;另一方面,重点关注模具拆装的快速,以及减少模具维修维护,更换易损件的时间。
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.
