挡渣块模具的结构特征是按照铁路应用所使用的规格而言的，按照所提供的挡渣块模具图纸进行模具的生产工作。挡渣块模具的使用属于专属领域，因为挡渣块只有在铁路建设的时候才会用到，除了常规490*200*250mm型号外，还有很多异形的存在。为了保证在铁路建设的时候都能够使用到图纸所需要的挡砟块，有时候将很多异形的挡渣块的生产来使用钢模具替代，这样能够有效节省挡渣块塑料模具的开模费用，从而降低生产成本。挡渣液压钢坝块钢模具生产的挡渣块预制块外形也是非常不错的，而且节省了胎具费用，在脱模速度、价格方面优势比较明显。
The structural features of the mould are in accordance with the specifications used in railway application, and the production of the mould is carried out according to the provided mould drawings. The use of mould for blocking slag block belongs to the exclusive field, because the block can only be used in railway construction. In addition to the conventional 490 * 200 * 250mm model, there are many abnormal shapes. In order to ensure that the ballast block required by the drawings can be used in railway construction, sometimes steel mold is used to replace the production of many special-shaped slag block, which can effectively save the opening cost of plastic mold for slag retaining block and reduce the production cost. The shape of the block is also very good, and the mould cost is saved, and the advantages in demoulding speed and price are obvious
