Horizontal molding line casting structure should be designed to meet the requirements of the casting process, the structure is designed to explain the following Heidi sand molding line castings manufacturers should pay attention to. First, to reduce the tendency to produce casting defects: 1, uniform wall thickness of the casting should strive to prevent shrinkage, thermal cracking, when the need to ensure that when the solidification conditions, you should try to have a wall thickness variation in one direction, when At the same time the need to ensure the solidification conditions, should try to make it cross-section having a wall thickness, etc.; 2, the connection between the casting wall and the wall should prevent sharp corners and metal concentration should be a gradual transition between the thick and the thin-walled to prevent mutation, so section and causing thermal stress concentration, the formation of thermal cracking, shrinkage, etc.; 3, local thick section castings, hollowed or cast should be adopted in the pore structure, and to strengthen the proper reinforcement ribs; 4, casting plane wall casting hole Application knurled reinforcement to reduce the wall thickness; 5, casting structure should make it possible unhindered shrinkage during cooling; 6, should be avoided in the cast has a large horizontal; 7, the casting waterways, gas and other large Sandwich lumen area, the column should be several connections. Second, to facilitate the manufacturing model, core box and styling: 1, casting the shape should be simple, so that from the mold, you should try to make the casting parting surface is flat, and the minimum number; 2, the casting cavity should strive casting no or little use of the core, when using core, should facilitate its support, fixed and exhaust out of the sand, where necessary, provided with adequate technical hole; 3, the inner and outer sides of the casting and the ribs and other structures should be played Direction of slope with a certain structure; 4 bosses cast on the body part and the casting should not differ too much, the best to take the same height, the same distance closer to the surface of several bosses, even as the best overall convex portion.
