水泥防撞墩模具结构设计时,尽量结构紧凑、操作方便,还要保证模具零件有足够的


强度和刚度;在模具结构允许时,模具零件各表面的转角应尽可能设计成圆角过渡,


以避免应力集中;对于凹模、型腔及部分凸模、型芯,可采用组合或镶拼结构来消除


应力集中,细长凸模或型芯,在结构上需采取适当的保护措施;对于冷冲模,应配置


防止制件或废料堵塞的装置。



防撞墩模具结构要确保模板的尺寸准确性,保证其表面是光滑没有瑕疵的,我们都是


严格按照设计图纸进行制作的,所以模具产品的线条更加平顺,边角的位置更加规整


。防撞墩模具在进行作业之前需要检查一下混凝土的塌落度,符合要求的混凝土才能


进行制作,在下料的时候要注意连续均匀,不能集中灌入导致应力集中,容易产生钢


模板错位或者变形的情况,在这个过程当中要随时注意混凝土的质量,已经受潮的混


凝土是不能投入到生产当中的,需要筛选以后才能使用,我们在振动的时候也要注意


混凝土的状态,而其标志就是混凝土不再有下沉的状况,表面不再有气泡产生,而且


混凝土预制块的表面十分光滑平坦

During the structural design of the cement anti-collision pier mold, try 


to be compact and easy to operate, and ensure that the mold parts have 


sufficient strength and stiffness; When the die structure allows, the 


corners of each surface of die parts shall be designed as fillet 


transition as far as possible to avoid stress concentration; For the 


concave die, cavity and some punch and core, the combined or inlaid 


structure can be used to eliminate the stress concentration. For the 


slender punch or core, appropriate protective measures shall be taken in 


the structure; For cold stamping dies, devices shall be equipped to 


prevent blocking of parts or waste materials.





The anti-collision pier mold 


structure shall ensure the dimensional accuracy of the formwork and ensure 


that its surface is smooth and free of defects. We are all made in strict 


accordance with the design drawings, so the lines of the mold products are 


smoother and the positions of edges and corners are more regular. Before 


the operation of the anti-collision pier mold, the slump of the concrete 


needs to be checked, and the concrete that meets the requirements can be 


manufactured. During blanking, pay attention to continuous and uniform, 


and do not pour it intensively, resulting in stress concentration, which 


is easy to cause dislocation or deformation of the steel formwork. Pay 


attention to the quality of the concrete at any time during this process, 


The damp concrete cannot be put into production and can only be used after 


screening. We should also pay attention to the state of the concrete when 


vibrating, and its sign is that the concrete will no longer sink, there 


will be no bubbles on the surface, and the surface of the concrete precast 


block is very smooth and flat
