压膜造型是用压縮空气的压力隔着一层胶皮膜,直接来压实砂型。我厂根据这一原理試制了一台簡易压膜造型机。这种造型机构造簡单,生产效率高,为广泛地实現造型机械化創造了有利条件。压膜造型机的构造和使用压膜造型机的构造如图1,主要可以分工作台、摇臂、压头三个部分。这台压膜机可以压制300×400公厘砂型。由于压头可以通过搖臂来轉动,所以可以两个人在同一台造型机上交差造型。操作时,先将上砂箱反扣在工作台上,上面放上型板,再将下箱按定位銷反扣在型板上面,然后在下箱上面放套箱。这时就可以依次放入界砂、面砂和背砂。装
Pressure film molding is the pressure of compressed air across the layer of rubber film directly to compaction sand. I plant based on this principle trial production of a simple film molding machine. This modeling machine structure is simple, high production efficiency, to create a wide range of mechanical mechanization has created favorable conditions. The structure and use of the film molding machine The structure of the film molding machine shown in Figure 1, the main can be divided into workbenches, rocker arm, head pressure three parts. This machine can suppress 300 × 400 mm sand mold. As the pressure head can be rotated through the rocker arm, so two people in the same molding machine cross shape. Operation, the first anti-buckle on the table in the workbench, placed on the template above, and then under the box by positioning pin anti-buckle on the template above, and then placed in the box under the box. At this time you can turn into the community sand, sand and sand back. Loaded
