近年来我国井盖模具产品开发取得了长足进步,我国已成为模具制造大国.我国工业水平大范围的快速增长,这与水井盖模具行业发展是息息相关的.
In recent years, China's well cover mold product development has made great progress, China has become a big mold manufacturing country. The rapid growth of China's industrial level is closely related to the development of water well cover mold industry

聚丙烯和ABS工程塑料的井盖模具,在浇筑预制前一定要在塑料模具内壁涂抹一定厚度的脱模剂,脱模剂一般可以是费机油、洗涤液或其他一些有机溶剂,
Before pouring and prefabricating the well cover mold of polypropylene and ABS engineering plastics, a certain thickness of release agent must be applied on the inner wall of the plastic mold. The release agent can generally be oil, detergent or other organic solvents,

在根据水泥预制件的形状配合相关脱模机械设备来进行脱模,最为方便,而且水泥预制件脱模完成整体 质量更为****,不太容易会造成其缺角、表面裂纹等次品产生.相关的配套机械设备.
It is most convenient to demould according to the shape of cement preform with relevant demoulding machinery and equipment. Moreover, the overall quality of demoulding cement preform is better, and it is not easy to cause defective products such as lack of corner and surface crack

井盖模具及预制件都是平底结构,那么可以使用振动台来调整震动频率,非常容易.又或者一些水泥栏杆的预制脱模,可以使用离心机转动脱模,道理其实跟振动台差不多,只是用离心机可以更好的保障圆柱体形状的水泥预制件质量更佳.
Well cover mold and prefabricated parts are flat bottom structure, so vibration table can be used to adjust the vibration frequency, which is very easy. Or for the prefabricated demoulding of some cement railings, the centrifuge can be used to rotate demoulding. The truth is similar to that of the shaking table, but the centrifugal machine can better guarantee the quality of the cylinder shaped cement prefabricated parts
