造型机定义：
用于制造砂型的铸造设备。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、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。
造型机发展及分类：
造型机最早出现于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压实式、震实式、震压式、射压式造型机和抛砂机。
造型机组成单元及特点：
造型机由机身、起模机构、震击压实机构、转臂压头部分及气动管路系统等部件组成。
1.机身为一坚固的空心框架工件，上部支撑转臂压头部分，压实时转臂勾住机身使压实力由机身承受，机身与震击机构用螺栓连接在一起，转臂压头部分，压头固定在可以回转的摇臂上，压头有螺旋升降机可根据砂箱高度调至压头至砂箱的距离
2.转臂是通过手拉阀控制油缸活塞往返运动，实现正臂和转臂运动。
3.起模结构由两只起模缸、连杆、平衡轴、起模台、起模杆等组成，起模缸启动时带动连杆、平衡轴、起模台使四根顶杆同时顶起砂箱起模。
4.震击压实结构。采用弹簧微震气动压实结构，压实震击使震动增加。起模时夹紧气缸将震实缸体锁紧，落模时夹紧气缸松开。
5.气动管路系统：输入的压缩空气，经空气过滤器去除压缩空气中的水及杂质，然后经油雾器注入润滑油，供给各气动元件和机构，机器动作由手拉阀控制台实现。
6.气源供给和润滑。机器是由气源作能源和油做润滑来实现工作的。进气压力大小和油量大小分别由减压阀和调油阀来调节。气源经过油雾器时根据虹吸原理将油吸入管路，雾状进入各管路系统进行润滑。
造型机合理使用：
1、遵守造型机和制芯机通用操作规程。
2、造型机起模时，顶杆必须平稳而又同步上或，否则，通知维修人员修理。
3、造型机/html/Molding-machine/42.html
压实时，压砂横梁转架应平稳地转动，不要操作过猛，产生冲击。
4、操作者在生产前后必须注意模具是否良好，外模与芯模的定位销是否配套。
5、操作造型机的工作人员应思想集中。
6、造型机合箱完工后，应按工艺规定，将模子吊搬到制定的浇注点（线）。摆放整齐，并加以压铁或卡子锁箱。杂件必须注明记号。
7、造型机砂箱不准堆放太高，一般不得超过两米，所用工具必须堆放整齐，防止发生事故。
8、使用喷灯时应注意安全，防止火灾发生，使用行灯必须是36V以下低压灯泡，禁用220V以上高压灯泡。
9、造型机使用行车时应先检查吊具是否良好，起吊时应将钩子扎牢链条拉直，不准斜吊和超负荷起吊。
10、严禁在起吊砂箱下面修模操作。大型砂箱开箱，翻身垫箱时必须用方形物件垫妥。
11、造型机 使用的砂箱必须牢固，搭手要完整无裂纹和弯曲现象。Molding machine definition:
Used in the manufacture of sand mold casting equipment. Its main function is: sand filling, the loose sand filling into the sand box; Tight sand, through vibration compaction, the compaction, the shock pressure, different methods, such as the loose sand in the sand box tight, make the sand mould is necessary in the process of handling and casting strength; Draw, use different institutions to tighten solid after withdrawal of sand mold.
Molding machine development and classification:
Molding machine first appeared in the middle of the 19th century, the early moulding machine is a kind of simple manual compaction with a draw, then using compressed air as shock compaction and dynamic compaction sand. In 1890 the shock moulding machine, make modelling efficiency and precision of sand mold have been improved.
Molding machine according to the method of tight sand compaction can be divided into different type, vibrated type, pressure type, squeeze moulding machine and the sand slinger.
Molding machine component unit and features:
Molding machine consists of fuselage, stripping mechanism, shock compaction mechanism, jib head parts and components such as pneumatic piping system.
1. The fuselage artifacts for a solid hollow frame, the upper supporting arm head part, pressure hooked fuselage make real-time transfer arm strength by the fuselage, under the fuselage with shock bolting together, jib head part, head is fixed on the can rotary arm, head has a spiral elevator can be adjustable according to the height of sand box to head to the distance of the sand box
2. Turn the arm by hand valve control cylinder piston movement back and forth, positive arm and arm movements.
3. The die structure from two die cylinder, connecting rod, balance shaft, draw, draw pole etc, draw cylinder startup drive the connecting rod, balance shaft, draw four plunger jacking sand box draw at the same time.
4. Shock compaction structure. Use spring microtremor pneumatic compacting structure, increases vibration compaction hammer. Draw will be vibrated when clamping cylinder lock cylinder body, when clamping cylinder to loosen.
5. Pneumatic piping system: input the compressed air, the air filter to remove water from compressed air and impurities, and then through the oil mist lubricating oil injection and supply pneumatic components and institutions, the console machine action by hand valve.
6. Air supply and lubrication. The machine is made up of gas source for energy and oil lubrication to implement the work. Size of the inlet pressure and oil amount respectively by the pressure reducing valve and valve to adjust. Gas source through according to the principle of siphon oil mist detector will oil suction pipe, lubrication mist into the piping system.
Molding machine is reasonable use:
1, abide by the molding machine and core-making machine general operation procedures.
2, molding machine, stripping, plunger, or must be smooth and synchronization, otherwise, notify the maintenance personnel to repair.
3, molding machine pressure real-time, sand bar bogie should rotate smoothly, don&＃39;t too hard, operation impact.
4, the operator must pay attention to the mold are in good condition before, during, and after production, mold and core mold positioning pin is necessary.
5, molding machine operation personnel should be centred.
After the completion of the 6, molding machine box, should according to the provisions of the process by pouring mold crane moved to formulate point (line). Well organized, and weight or clamp lock box. Miscellaneous must indicate a mark.
7, molding machine sand box are not allowed to pile up too high, generally no more than two meters, the tool must be neatly stacked, prevent accidents.
8, when using a blowtorch, should pay attention to safety, prevent fire, using the line must be under 36 v low voltage lamp bulbs, disable more than 220 v high pressure lamp.
9, molding machine using driving should first check whether the spreader is good, when the lifting hook should be fastened chain straightening, no tilt hanging and overload lifting.
10, is strictly prohibited under the sand box operation mode operation. Large sand box out of the box, turn mat boxes square objects must be used when appropriate.
11, molding machine using sand box must be firmly, Mr To complete no crack and bending phenomenon
