The design adopts independent sand injection and filling sand at the top and bottom, with the aim of making the sand filling method closer to manual molding, ensuring that the internal of the sand box can obtain a more uniform compactness when forming the sand mold, and allowing more complex or large concave and convex molds to be made into perfect sand molds through automatic molding machines. This machine is also a derivative of conventional automatic molding machines, so it has been widely recognized and used by many casting enterprises in recent years.
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;
This sandblasting machine was developed and put into use in 2018. After 4 years of feedback from users and repeated experiments, we launched a new type of machine in 2022. The main solution is to solve the problem of clogging of the sand injection port caused by prolonged use of the sand injection method machine in the case of high humidity and poor fluidity of the sand used for casting molding. The launch and use of the new machine have received unanimous praise from users, and so far, the maximum customizable sand box size range has covered 1200mm. The larger the sand box size, the higher the requirements for the machine's sand shooting performance. This also indicates that the new horizontal parting molding machine for top and bottom sand shooting has a stable sand shooting system;
2. During normal use, the upper and lower sand boxes can selectively open half of the number of sand injection ports. Under the same pressure and time, opening half of the number of sand injection ports and opening all the sand injection ports can complete the sand injection in the same time. That is to say, under the same pressure, the number of sand injection ports decreases and the speed of sand injection is faster (referring to only opening half of the number of sand injection ports); It is precisely because of this design that we can use this machine to shape the mold at a specific position, open the corresponding sand injection port to achieve targeted sand injection at the specific position, making the sand injection effect and the uniformity and pre compaction of the sand mold cavity before compaction more ideal.
3. In terms of machine structure, we have adopted a dual sand blasting cylinder design, which separates the sand blasting cylinders of the upper and lower sand boxes separately, allowing separate sand blasting cylinders to be used as corresponding sand boxes for sand blasting. For machines with large-sized sand boxes, the load of the sand blasting system is greatly reduced, and PE high molecular polyethylene breathable plates are installed on the inner side of the sand blasting cylinder. New designs are adopted for the air intake and guide systems, Enable the molding machine to easily and smoothly complete sand shooting with lower air pressure during operation; The sand box and shooting cylinder are assembled as a whole and have undergone airtightness treatment, ensuring that there is no air leakage or dust flying during the shooting process, and making the shooting system more stable and durable; When the machine is compacting and demolding, the upper sand blasting cylinder and sand box operate synchronously up and down, while the lower sand blasting cylinder and sand box are fixed to the frame and base. Considering the long-term and frequent use of the equipment and potential problems, we have also reserved cleaning and maintenance openings at the bottom of the sand blasting cylinder and hydraulic maintenance space at the bottom of the machine;
4. The new horizontal parting molding machine with top and bottom sandblasting is equipped with mold lifting devices, making it easy for operators to quickly and easily replace molds; The sand mold pushing device has been changed to a servo electric cylinder, increasing its service life and making the operation more stable and convenient for precise adjustment and control; On the hydraulic assembly, a servo motor has also been used as the power output, which has fast and accurate response speed and can handle more complex program instructions for matching; In addition, comprehensive intelligent design has been made for the safety warning and fault display of the entire machine, with the aim of making it more practical, durable, and reliable during use;
5. The horizontal parting molding machine with top and bottom sand injection is more comprehensive for molds with complex and deep concave shapes, and has the highest coverage rate in a wide variety of casting production. This is also a comprehensive horizontal molding machine that we have developed after years of continuous experimentation and summary;
