Large size sand casting automatic molding machine

• Introduction to Features :

• A large-scale horizontal molding machine developed according to the requirements of foundry enterprises for tidal sand molding. Larger sand molds require more casting sand to be filled with air flow at once. Therefore, the design of using two sand injection cylinders to simultaneously inject sand on both sides of the sand box can reduce the gas pressure of sand injection and ensure that the sand box is uniformly filled to achieve the pre compaction of the sand mold, avoiding the shadow area of the sand mold and shortening the sand filling stroke, Enable it to easily complete sandblasting and achieve the desired effect in a specific short period of time during the modeling process.

• Detailed remarks:

• 1) This type of machine can customize specific sand box sizes according to specific needs;
  2) Use # 46 anti wear hydraulic oil;
  3) Double sided steel or aluminum molds are required;
  4) Fully automatic one button intelligent continuous or single cycle operation molding, automatic fault detection and alarm, emergency locking and safety warning;
  5) Language switching can be selected according to regional needs;
  6) Hydraulic compaction through air pressure and sand addition;

  7) You can choose the appearance color of the spraying equipment according to user needs;

  In the field of casting, a large proportion of casting enterprises produce castings with larger sizes or require a certain amount of molten iron to be poured and improve efficiency within a specific production time. Therefore, the requirements for the size of the sand box of automated molding machines are also higher. This double-sided and double-sided sand shooting horizontal parting automatic molding machine is developed and manufactured according to this requirement. The size range of the sand box is around 700mm-1600mm, and it adopts a structural design of two sand shooting cylinders shooting sand from both sides simultaneously. The purpose is to fully and evenly fill the casting sand inside the sand box by shooting sand from both sides when the size of the sand box is large, resulting in long shooting travel distance and other factors, And the method of shooting sand from the side can avoid the influence of gravity on the casting sand to the greatest extent. Therefore, under a certain air pressure, the flow rate of gas carrying sand is also greater, which meets the demand for casting sand in larger sand boxes during shooting;

   

   

  

   

   

  As of November 2023, we have provided 86 large-sized sand box double-sided sandblasting horizontal parting automatic molding machines to China and even the international community. The maximum size of the sand box can reach 1620mm. In Guangdong and Shandong provinces of China, two 1620mm x 1400mm large-sized sand box double-sided sandblasting horizontal parting automatic molding machines have been put into operation in casting enterprises, and have been widely used and recognized by users in casting production; This is also the progress we have made by daring to try and break through;

   

   

  

   

  3. In previous usage cases, this model has been used for automatic casting production of large-sized castings such as cast iron manhole covers, well rings, grates, fireplaces, fire hydrants, counterweight iron, and park patterned iron;
