1. The composition, layout principle and type of the production line, in accordance with a certain technological process, through transportation equipment: mold transportation The machine, the roller table, etc. are connected, and a certain control method is used to form a machine Modeling and automated modeling production system
2. Factors affecting the fabric of the modeling production line There are six aspects:
2.1 Modeling process, such as modeling materials and modeling methods; type of metal: cast iron,Cast steel
2.2 Casting size and required cooling time; casting quality and precision requirements, etc.;Single unit line or multi-unit line, etc.
2.3 The operation mode of the production line: continuous, pulsating or intermittent
2.4 The structure, performance and supporting methods of auxiliary machinery
2.5 The automatic control method and the signaling device will also affect the production line. The attached machine and
The local structure of the conveyor and the layout of the production line
2.6 Plant conditions and environmental protection requirements affect the selection of main and auxiliary machines and the production line The layout also has an impact
3. The principle of modeling production line cloth
3.1 The layout of the production line should be determined according to actual conditions and specific requirements
3.2 The casting process selected for the production line must be tested and proved to be feasible,And after feasibility demonstration
3.3 The production line should meet the requirements of the production program
3.4 The production line is as far as possible to realize the mechanization of pouring, which can not only prevent the casting workers from danger and It is freed from heavy labor and can increase the utilization rate of the line
3.5 Pay attention to solving the problem of production balance between each process in the molding production line to achieve balance Production, improve equipment utilization and productivity
3.6 The transportation mode of the production line should adopt the flexible connection of the segmented cumulative raceway, or Add buffer links between processes
3.7 Each mechanical transmission mode of the production line should adopt electric, hydraulic, pneumatic and oil resistance.Nigeria’s comprehensive transmission with automatic lubrication system
3.8 The production line control system should adopt decentralized control
3.9 The production line has high maintainability, which means simple structure, durability,Pieces do not require scarce materials, etc.
3.10 Good building adaptability, small floor space, no large dynamic load in the venue The load and the pit, the lifting equipment serving the production line has a small load, etc.
4. Several types of molding production line layout
For the convenience of addressing, people are accustomed to adopting the name of the molding line host for modeling Line classification. Such as pneumatic micro-seismic molding line, high-pressure molding line, static Press molding line, vertical parting boxless injection molding line, horizontal parting off-box compaction molding Line etc.
5. Main auxiliary machines on the production line
5.1 Sand scraping machine, milling and pouring riser machine and blow hole machine For medium and low pressure molding machines, plow-shaped sand scrapers are often attached to the side of the box.For high-pressure molding machines, a rotary sand scraper must be installed.The gate milling machine uses a high-speed rotating shaped blade to cut the sand mold with higher hardness.The shape of the sprue cup.The vent hole can be pierced with the vent needle of the puncture machine. For fine and deep vents, then''''''''S shop It can be pierced out with a pneumatic drill instead of a puncture needle
5.2 Case Turning Machine
The main function of the box-turning machine is to turn the finished lower type 180°, and some upper types also turn over.Turn, the purpose is to check whether the sand mold is defective, repair the mold and turn off the floating sand
5.3 Drop box machine
The box drop machine is mainly used to steadily place the turned down mold or the completed mold Place on the mold conveyor
5.4 Forming machine
Process requirements: During the molding process, the upper and lower sand molds must be accurate; the action Smooth and no impact; rapid and flexible action.
5.41 Static closing machine This closing method is accurate and easy to ensure the quality. The machine The structure is also relatively simple, and is currently more commonly used.
5.42 Dynamic type closing machine Dynamic type closing is required for the upper and lower types during the movement.They are put together accurately and steadily, which leads to the complicated structure of the forming machine and it is difficult to guarantee The action is smooth and accurate, and it is easy to malfunction.
5.5 Core setting equipment
5.6 Iron Press
Molding production line. Equipment for pressing iron, taking iron and transporting iron.
5.61 Relying on the self-weight of the mold to consciously increase the weight of the upper mold, which can also serve as a weight
5.62 The sand box is pressed with the cylinder on the bracket while the additional pressure is poured during pouring.
5.63 Sand box with clamping mechanism
5.7 Case sorting machine, the upper grabbing case sorting machine is similar to the upper grabbing drop case machine
5.8 Box punching machine and mold ejection machine
5.9 Other auxiliary equipment Such as the reversing machine, the cleaning machine of the trolley table, the core turning machine, the core grinding machine, etc.
6. Casting conveyor
The casting conveyor is used in the molding production line to mold, set the core, mold, press iron, and pour The main transportation equipment connected by the processes of injection, cooling, and sand falling.
