| 射压式造型机它是利用压缩空气将型砂均匀地射入砂箱预紧实，然后再施加压力进行压实。常用的有垂直分型无箱射压造型机和水平分型脱箱射压造型机。垂直分型无箱射压造型机造型不用砂箱，型砂直接射入带有模板的造型室，所造砂型尺寸精度高，因砂箱两面都有型腔，生产率很高，但下芯比较困难，对型砂质量要求严。水平分型脱箱河北立体车库 消防报警器塑料配件 电缆接地箱 电缆保护接地箱 塑料土工格栅 消弧线圈装置 射压造型机利用砂箱进行造型，砂型造好后合型脱箱，下芯比较方便，生产率高。抛砂机
利用旋转叶片抛出砂团紧实砂型。抛砂机的特点是填砂与紧实同时进行，机器结构简单、重量轻，适应性强。但叶片易磨损，生产率较低。 Injection molding machine uses compressed air to inject molding sand evenly into sand box for pre compaction, and then apply pressure for compaction. There are two kinds of injection molding machines in common use: vertical type and horizontal type. The vertical parting non box injection molding machine does not use a sand box for molding, and the molding sand is directly injected into the molding room with a template. The size accuracy of the sand mold is high. Because there are cavities on both sides of the sand box, the productivity is very high, but it is difficult to lower the core, and the quality requirements of the molding sand are strict. The horizontal parting and decanting injection molding machine uses the sand box for molding. After the sand mold is made, the final closing and decanting is convenient to lower the core, and the productivity is high. The sanding machine uses the rotating blade to throw out the sand mass and compact the sand mold. The features of the sanding machine are that the sand filling and compaction are carried out at the same time, the structure of the machine is simple, the weight is light, and the adaptability is strong. But the blade is easy to wear and the productivity is low. |
