公路鐵路界樁里程碑模具   河北宏旭模具

   公路鐵路界樁里程碑模具使用方法：在公路鐵路界樁里程碑模具的制造過程中要加強檢驗，把檢驗的重點放在尺寸精度上。雖然是在選定成型材料、成型設備時，在預想的工藝條件下進行界碑模具設計，但是人們的認識往往是不完善的，因此必須在界碑模具加工完成以后，進行試模試驗，看成型的制件質量如何。發(fā)現總是以后，進行排除錯誤性的修模。公路鐵路界樁里程碑模具出現不良現象的種類居多，原因也很復雜，有界碑模具方面的原因，也有工藝條件方面的原因。在修模前，應當根據界碑模具出現的不良現象的實際情況，進行細致地分析研究，找出造成塑件缺陷的原因后提出補救方法。修理地界碑模具更應慎重，沒有十分把握不可輕舉妄動。其原因是一旦變更了界碑模具條件，就不能再作大的改造和恢復原狀。Application method of milestone mould for highway and railway boundary piles: the inspection shall be strengthened in the manufacturing process of milestone mould for highway and railway boundary piles, and the inspection shall focus on the dimensional accuracy. Although the boundary pillar mold design is carried out under the expected process conditions when the molding materials and equipment are selected, people's understanding is often imperfect. Therefore, after the boundary pillar mold processing is completed, the mold test must be carried out to see the quality of the molded parts. When it is found that it is always wrong, repair the mold to eliminate errors. There are many kinds of bad phenomena in milestone molds of highway and railway boundary piles, and the reasons are also very complex, including boundary pillar molds and process conditions. Before repairing the mold, detailed analysis and research shall be carried out according to the actual situation of the bad phenomenon of the boundary pillar mold, and the remedial methods shall be put forward after finding out the causes of the defects of the plastic parts. Repair the boundary tablet mold should be more careful, not very sure, do not act rashly. The reason is that once the boundary pillar mold conditions are changed, it can no longer be greatly transformed and restored to the original state.
