1.用於制造砂型的铸造设备。[1]它的主要功能是:填砂,将松散的型砂填入砂箱中;紧实型砂,通过震实 1. Used for sand casting equipment. The main function of [1] is to fill sand and fill the sand box with loose sand. Compact sand, by vibration 造型机 Molding machine 造型机 Molding machine ﹑压实﹑震压﹑射压等不同方法使砂箱中松散的型砂紧实﹐使砂型在搬运和浇注等过程中具有必要的强度;起模﹐利用不同机构将模样从紧实后的砂型中取出。造型机最早出现於19世纪中期,早期的造型机是一种简单的手动压实带起模的机构﹐后来采用压缩空气作为震实和压实型砂的动力。1890年出现了震击式造型机﹐使造型效率和砂型精度都有了提高。造型机按其紧实型砂的方法不同可分为震压式﹑震实式﹑压实式。 Different methods such as compaction, shock pressure and ejection pressure are used to tighten the loose sand in the sand box so as to have the necessary strength in the process of handling and pouring. The mould can be removed by using different mechanisms to tighten the shape of the sand. The machine was first developed in the mid-19th century, and the early moulding machine was a simple manual compaction and compaction, which was later adopted as the power of compaction and compacted sand. In 1890, the shock type moulding machine appeared, which improved the molding efficiency and the grinding accuracy. According to the method of compact sand, the molding machine can be divided into seismic pressure type, seismic compaction and compaction. 2.震压式造型机 对震实的砂型再进行压实﹐可以获得上下部紧实的砂型。常用的是微震压实式造型机(见图 微震压实式造型机 )﹐利用工作台下落与浮动的震铁相撞﹐微震紧实型砂﹐再进行压实。微震是以较高频率(500～1000次/分)﹐小振幅(5～25毫米)的振动代替震击式造型机的低频率 (60～120次/分)﹑大振幅的振动。这种造型机造出的砂型质量好﹐对基础要求也较低。 2. The jolting moulding machine can be compacted to the compacted sand, which can obtain the compactness of the upper and lower parts. It is commonly used for the micro - vibrating compaction moulding machine (see the microseismic compaction moulding machine), and the falling of the workbench is in collision with the floating shock iron, which compacts the solid sand and compacts the compaction. The microearthquake is a high frequency (500 ~ 1000 times/min), and the small amplitude (5 ~ 25mm) is substituted for the low frequency (60 ~ 120 times/min) of the jarring moulding machine and the vibration of the vibration amplitude. This type of molding machine has good quality and low base requirement. 3.震实式造型机 此种造型机又可分为震击式和微震式造型机两种。砂箱和模样固定在造型机的工作台上﹐利用工作台下落时与砧座撞击面的相撞﹑砂粒的惯性来紧实砂型。这种造型机噪声严重﹐所造砂型上部的紧实度很低﹐已被微震压实造型机所代替。 3. The jarring moulding machine can be divided into two types: shake-out type and microseismic moulding machine. The sand box and the shape are fixed on the working platform of the molding machine, and the impact of the impact surface of anvil on the head of the table and the inertia of the sand grain is used to tighten the sand mold. This kind of molding machine noise is serious, the compactness of the sand type upper is very low, have been replaced by the microseismic compaction moulding machine.
