为了提高压铸件质量,压铸机压射机构的性能是十分重要的。国外许多厂家生产的压铸机,压射机构为三级压射,一、二级可调,三级增压建压时间短,一般可达0.01～0.03秒。而国产压铸机,如J1113、J1113A型,虽有三级压射,但因三级增压时间缓慢,对铸件产生增压效果不明显。为了解决这一问题,81年以长风机械厂为主研制成功了《三级压射快速建压装置》,在几台压铸机上试用,其建压时间不超过0.04秒;83年上海钢模厂、上海第一汽车附件厂和上海电表厂协同攻关,设计制造成功了DDK高性
In order to improve the quality of die casting, die casting machine pressure mechanism is very important. Many foreign manufacturers of die-casting machine, injection mechanism for the three shots, one or two adjustable, three supercharger pressure build time is short, generally up to 0.01 to 0.03 seconds. The domestic die-casting machine, such as J1113, J1113A type, although the three shots, but the three supercharger time is slow, supercharged effect is not obvious casting. In order to solve this problem, 81 years to Changfeng Machinery Factory successfully developed the “triple injection rapid pressure device” in a few die-casting machine on the trial, the construction pressure of not more than 0.04 seconds; 83 years Shanghai Steel Die Factory, Shanghai First Automobile Accessories Factory and Shanghai Electric Meter Factory collaborative research, design and manufacture of a successful DDK high
