什么是路沿石模具
路沿石模具是生产水泥预制路沿石的模具模型。路沿石是指用花岗岩材质或者水泥预制制作的用在路面边缘的界石，路沿石也称道牙石或路边石、路牙石。
The mold of the road along the stone is the mould for the production of the prefabricated road along the stone. Lu Yanshi refers to the use of granite material or cement prefabricated production used in pavement edge line, Lu Yanshi also praised the calculus or roadside stone, luyashi.
路沿石是在路面上区分车行道、人行道、绿地、隔离带和道路其他部分的界线，起到保障行人、车辆交通安全和保证路面边缘整齐的作用路沿石主要是道路两侧长条形水泥预制块或石材切割而成，路沿石模具主要是以生产预制混凝土路沿石为主，模具的材质一般分为塑料注塑成型还有钣金钢模具成型，生产原理是将混凝土倒入塑料模具或铁模具内，等水泥凝固后在拆模或者脱模成型，路沿石塑料模具主要采用工程聚丙PP注塑成型，材质直接影响模具的使用寿命。
Lu Yanshi is the distinction between the roadways, sidewalks, greenbelt, belt and other parts of the road line on the road, pedestrians and vehicles to ensure traffic safety and ensure the effect of road pavement edge and along the stone road on both sides of the strip is mainly cement block or stone cutting, Lu Yanshi mold is the main production Precast concrete curbstone, mold material generally divided into plastic injection molding and sheet steel mold, production principle is the concrete poured into the plastic mold or iron mould, cement solidification after stripping or demoulding and curb plastic mold mainly adopts polypropylene PP injection molding, the material directly affecting the mold service life.
