The maximum deformation of the side wall of the high-pressure molding box allowed: high-pressure molding, sand box models, the side wall of the flask under a lot of pressure on the side, the side effect of pressure causes deformation of the side wall of the flask, especially when there is no box belt, Deformation more serious. Therefore, sand box must have sufficient strength and rigidity, Qingzhou sand box in use should not be plastically deformed. Elastic deformation should be restricted. This is because as the pressure load removal, sand box sales, in a state of elastic deformation of the walls of the box are also removed with force inward bounce. Casting sand box body design ① determine the type of sand box, select the flask material. ② riser arrangement and eat according to the amount of sand and other factors that determine the size of sand inside the outline. ③ determine the structure and thickness of the wall of the flask. ④ OK with me, strengthen the number, size and arrangement of the ribs and the air vent. ⑤ box set ears, and rings Xiangzhou location, the choice of positioning pins and pin sets. ⑥ flask fastening methods and aids design. Qingzhou sand box sand box _ _ Dragon Industrial production provided by the Industrial Development Co., Ltd. Shandong dragon. Qingzhou sand box sand box _ _ Dragon Industrial production in Shandong dragon Development Co., Ltd. (www.julongshiye.com/) this year introduced a new upgrade, the above picture is for reference only, please call the contact picture on this page or telephone obtain the latest information, contact: Mr. Wang.
