We adopt a removable (drawer style) design for the lower sand box located in the molding machine, which facilitates operators to accurately and easily place the coated sand core head, such as casting shapes such as valves, pipe fittings, brake discs, etc. after the sand mold is compacted and demolded. In the programming of the molding machine, it is possible to choose whether to remove the sand box according to actual operational needs. In the production of castings that do not require the placement of core heads, the function of removing the sand box can be turned off to shorten the molding cycle; At the same time, in the design of the mechanical structure of the molding machine, we also take into account the durability of the machinery and ensure the precision of the upper and lower molding sand boxes;
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;
From the early stage of the development of this machine, we analyzed the mechanical motion force and combined it with the structural design of mechanical plane motion and balance. We mainly considered that the repeated sliding and retraction of the lower sand box can always maintain a stable and accurate completion of this action in long-term use, avoiding problems such as misalignment of the sand mold caused by the misalignment of the upper and lower sand boxes. At the same time, we also need to consider the reliability and service life of the mechanical structure. On both sides of the lower sand box of the molding machine, precision sliding rails and steel limit rollers are installed. A hydraulic cylinder is used to push the lower sand box out of the equipment for 2/3 of its stroke, and an extension platform for support and clamping is installed at the bottom of the pushed out part of the sand box, so that it can also be in a balanced and stress free state when the lower box is pushed out;
This type of horizontal parting automatic molding machine was officially launched and provided to casting enterprises in 2019. Its feature is that after the molding machine sand box is compacted and demolded, the lower sand box can choose to slide out in a drawer style, making it convenient for operators to accurately place the core inside the sand chamber, reducing the difficulty of operators' work and improving personal safety. After the core is placed, the lower sand box can be retracted and the upper and lower box sand molds can continue to be automatically closed, When automatically shaping castings that do not require the placement of cores, this action can also be turned off through the touch screen.
The drawer type sliding out automatic molding machine for the lower sand box was applied to the conventional horizontal parting automatic molding machine for a single sandbox in 2019. Subsequently, the research and development of the large-sized sandbox double sandbox horizontal parting automatic molding machine and the top+bottom sandbox horizontal parting automatic molding machine were also applied to these two types of automatic molding machines. Therefore, regardless of the sandblasting method of the automatic molding machine, it can be upgraded and installed as a drawer type sliding out automatic molding machine with a lower sandbox according to actual production needs; Compared with conventional non sliding sand box molding machines, the biggest difference between the two is that the sliding sand box automatic molding machine requires two sets of oil cylinders, the upper and lower, to move and compact simultaneously. Therefore, the production cost is slightly higher than that of conventional automatic molding machines.
