Technical Field

[0001] This utility model relates to the field of casting and forming technology, specifically to a sand casting and forming device for cast iron wear-resistant parts. Background Technology

[0002] Sand casting molding equipment is the core equipment used in sand casting process. Through a specific structure and process flow, liquid metal is poured into a mold formed by molding sand. After the metal cools and solidifies, the casting with the required shape and properties is obtained.

[0003] Currently, most existing sand casting molding devices for cast iron wear-resistant parts are designed for single-stage molding, which cannot produce multiple sets of sand blanks at the same time. They require repeated processes such as filling sand, compacting, and pouring, resulting in long production cycles. Especially in mass production, frequent repetitive operations consume a lot of time and manpower. In view of this, we propose a sand casting molding device for cast iron wear-resistant parts.

[0029] Please see Figures 1-7 This utility model proposes a sand casting molding device for wear-resistant cast iron parts, including mold a and mold b. Both mold a and mold b are equipped with cover plates 6. The outer walls of plate 1, plate 2 and plate 3 of mold a are slidably connected with positioning rods 8 for positioning mold b and preventing deviation of the mold openings on mold a and mold b. Both cover plates 6 and bottom plates 5 are provided with handles. Mold a and mold b are both composed of plate 1, plate 2 and plate 3. Plate 1 and plate 2 and plate 2 and plate 3 are connected by hinges 4. There are two sets of hinges 4 between plate 1 and plate 2 and between plate 2 and plate 3 to improve the stability of the connection between plate 1 and plate 2 and plate 2 and plate 3. Locking components are provided on plate 1 and plate 3.

[0030] In an embodiment of this utility model, in order to assemble plate 1, plate 2, and plate 3 into a mold, the locking assembly specifically includes a fixing block 11, which is fixedly connected to the outer wall of plate 1, a rotating rod 12 is rotatably connected to the inner wall of fixing block 11, a bolt 13 is fixedly connected to the side wall of rotating rod 12, the bolt 13 passes through locking block 14 and is threadedly connected to locking block 14, and a fixing block 2 31 is fixedly connected to the outer wall of plate 3, and a slot 32 is provided in fixing block 2 31.

[0031] Furthermore, both mold a and mold b are equipped with a base plate 5, and a positioning pin 51 is fixedly connected to the outer wall of the base plate 5.
