射壓式造型機(jī)它是利用壓縮空氣將型砂均勻地射入砂箱預(yù)緊實(shí)，然后再施加壓力進(jìn)行壓實(shí)。常用的有垂直分型無(wú)箱射壓造型機(jī)和水平分型脫箱射壓造型機(jī)。垂直分型無(wú)箱射壓造型機(jī)造型不用砂箱，型砂直接射入帶有模板的造型室，所造砂型尺寸精度高，因砂箱兩面都有型腔，生產(chǎn)率很高，但下芯比較困難，對(duì)型砂質(zhì)量要求嚴(yán)。水平分型脫箱河北立體車庫(kù) 消防報(bào)警器塑料配件 電纜接地箱 電纜保護(hù)接地箱 塑料土工格柵 消弧線圈裝置 射壓造型機(jī)利用砂箱進(jìn)行造型，砂型造好后合型脫箱，下芯比較方便，生產(chǎn)率高。拋砂機(jī) 利用旋轉(zhuǎn)葉片拋出砂團(tuán)緊實(shí)砂型。拋砂機(jī)的特點(diǎn)是填砂與緊實(shí)同時(shí)進(jìn)行，機(jī)器結(jié)構(gòu)簡(jiǎn)單、重量輕，適應(yīng)性強(qiáng)。但葉片易磨損，生產(chǎn)率較低。
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.
