河道护坡模盒生产出来的水泥河道护坡砖存在脱模难的问题，脱模是水泥砖制作的一个非常关键的步骤，脱模效率和脱模质量这两方面决定这工程的进度和水泥砖的品质，详细介绍护坡模盒脱模的流程，
It is difficult to demould the cement river slope protection brick produced by the river slope protection mold box. Demoulding is a very key step in the production of cement brick. The demoulding efficiency and demoulding quality determine the progress of the project and the quality of the cement brick. The demoulding process of the slope protection mold box is introduced in detail,
1.对塑料模具进行加热处理，模具内的水泥在进行了二十四小时凝固后还可能会出现粘膜情况，这个时候我们可以进行对模具加热处理。通过水泥和塑料的热胀冷缩膨胀率不同来实现的，首先大量烧制50°热水，然后尽量选择在中午高温时段进行热水喷洒，这样塑料内壁与水泥件分离效率更加高。
1. Heat the plastic mold. After 24 hours of solidification, the cement in the mold may have mucous membrane. At this time, we can heat the mold. It is realized by the different expansion rates of cement and plastic. Firstly, a large amount of 50 ° hot water is fired, and then hot water is sprayed at high temperature at noon as far as possible, so that the separation efficiency of plastic inner wall and cement parts is higher.
2.选择专用的脱模剂脱模剂是水泥脱模的重中之重，它从一定意义上决定这水泥件是否能顺利的从模具当中“滑”下来。采用高性能的混凝土脱模剂，再向模具内浇筑水泥前先将模具内壁刷满一层脱模剂，这个过程尽量保证每个内壁涂抹均匀，做到“不漏壁”的效果，涂抹后的模具内壁应该是避免非常光滑、四周颜色均匀并且光亮。
2. The selection of special release agent is the top priority of cement demoulding, which determines whether the cement can slide down smoothly from the mold in a certain sense. High performance concrete release agent is used. Before pouring cement into the mold, the inner wall of the mold shall be coated with a layer of release agent. This process shall ensure that each inner wall is evenly coated to achieve the effect of "no leakage". The inner wall of the mold after coating shall be avoided to be very smooth, and the color around the mold shall be uniform and bright.
3.击打脱模，最后一步则是人工进行敲打脱模，需要准备的工具有水泥件橡胶垫或者软木，击打的橡胶锤，将模具倒放至于橡胶垫上，人工使用橡胶锤轻轻击打塑料模具外侧四周和底部，使得模具内壁与河道护坡砖顺利脱离不粘固，最后击打底部时要做到轻、慢、稳，击打完毕后把河道护坡模盒直接平稳垂直向上拿走即可。
3. Knock demoulding. The last step is to knock demoulding manually. The tools to be prepared are cement rubber pad or cork. The rubber hammer is used to lay the mold upside down on the rubber pad. The rubber hammer is used to gently tap the outside of the plastic mold around and at the bottom, so that the inner wall of the mold can be separated from the river revetment brick without sticking. Finally, the bottom of the mold should be light, slow and smooth After hitting, the mold box of river slope protection can be directly and stably removed vertically.
