国产护坡模具还存在一些缺陷,国产护坡砖模具设备在机床行业市场中的占有率很低,即使是在目前任务饱满的情况下,也应从长远发展出发,从战略高度去认识,并对这一市场进行充分研究与正确定位.特别是在中低档数控设备方面,国内企业也一样是大有可为的. 针对护坡模具的这种缺陷,国外企业非常重视,一方面,重点关注模具内冷却,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。大型护坡模具安装、拆卸如采用人工压压板等传统方式是非常占用时间的,通常需要一个班次.而国外,无论是压铸机还是压铸模具,都非常重视这个问题,包括模具的定位、模具的夹紧、顶出复位杆安装、行程开关连接、抽芯油缸油管连接、冷却水管连接等等,都做到快速连接,并且如果模具需要几个油缸或行程开关的接头在模具上串、并联好,做的非常人性化.而在型芯更换等其它细小环节上都下足了功夫,充分考虑了模具的使用性、模具的生产效率。
There are still some defects in the domestic slope protection moulds. The market share of the domestic slope protection brick moulds and equipment in the machine tool industry is very low. Even if the current task is full, we should proceed from the long-term development, understand from the strategic height, and make a full study and correct positioning of the market, especially in the field of middle and low-grade numerical control equipment. Domestic enterprises are also promising. In view of this defect of slope protection mould, foreign enterprises attach great importance to it. On the one hand, they focus on cooling in the mould, reducing the temperature balance of the mould by spraying, reducing the spraying time, reducing the cooling time of casting on the mould, improving the production rhythm and improving the production efficiency of die casting; on the other hand, they focus on cooling in the mould. Focus on the rapid disassembly and assembly of the die, as well as reducing the maintenance of the die, replacing the time of vulnerable parts. It takes a lot of time to install and disassemble large-scale slope protection moulds, such as using manual pressure plate, which usually requires a shift. However, foreign countries, whether they are die-casting machines or die-casting moulds, attach great importance to this issue, including the positioning of moulds, clamping of moulds, installation of ejection reset rods, connection of stroke switches, oil cylinder for core-pulling. Pipe connection, cooling water pipe connection and so on, all achieve fast connection, and if the die needs several cylinders or stroke switch joints in series and parallel on the die, it is very humanized. In the core replacement and other small links, all efforts have been made to fully consider the use of the die, the production efficiency of the die
