高速公路里程碑模具使用方法:在高速公路里程碑模具的制造過程中要加強(qiáng)檢驗(yàn),把檢驗(yàn)的重點(diǎn)放在尺寸精度上。雖然是在選定成型材料、成型設(shè)備時(shí),在預(yù)想的工藝條件下進(jìn)行界碑模具設(shè)計(jì),但是人們的認(rèn)識(shí)往往是不完善的,因此必須在界碑模具加工完成以后,進(jìn)行試模試驗(yàn),看成型的制件質(zhì)量如何。發(fā)現(xiàn)總是以后,進(jìn)行排除錯(cuò)誤性的修模。高速公路里程碑模具出現(xiàn)不良現(xiàn)象的種類居多,原因也很復(fù)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(yīng)當(dāng)根據(jù)界碑模具出現(xiàn)的不良現(xiàn)象的實(shí)際情況,進(jìn)行細(xì)致地分析研究,找出造成塑件缺陷的原因后提出補(bǔ)救方法。修理地界碑模具更應(yīng)慎重,沒有十分把握不可輕舉妄動(dòng)。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(fù)原狀。Use method of Expressway milestone mould: strengthen the inspection in the manufacturing process of Expressway milestone mould, and 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 Expressway milestone molds, 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.
