The following requirements should be paid attention to when making the curb stone plastic mold. The first qualified standard of the mold is the material, the second is the manufacturing process, and then the practicability. The mold is basically free from problems due to the restrictions of the above three requirements.
好的模具在外观和自身的质量上都是显而易见的,模具成型之后不要急于使用,用尺子测量一下看模具的尺寸是不是合格。
A good mold is obvious in appearance and its own quality. Don't rush to use it after the mold is formed. Measure it with a ruler to see if the size of the mold is qualified.
每个模具都是具有收缩量的,温度的变化是最明显的,在露天的场地上还好一点,主要是到了冬天保温室里面温度较高
Each mold has shrinkage, and the temperature change is the most obvious. It's better in the open field, mainly because the temperature in the insulation room is higher in winter
外界温度较低所形成的温度差距太大就很容易导致模具的损坏或是水泥成型以后脱不出模来。
The temperature difference formed by low external temperature is too large, which can easily lead to mold damage or failure to take off the mold after cement molding.
这样的现象应对措施,在预装混凝土之前把路沿石塑料模具里面喷刷上润滑剂就可以有效的防止水泥和模具粘连产生产不好脱模的现象。
Measures to deal with such phenomenon: spraying lubricant inside the plastic mold of the curb stone before pre installing the concrete can effectively prevent the adhesion between the cement and the mold, resulting in poor demoulding in production.
