[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example 1

[0023] like Figure 1 、 Figure 2 and Figure 3 As shown, the square slide casting mold includes a casting mold body 1, a parting cover plate 3 is provided on one side of the casting mold body 1, the side of the parting cover plate 3 close to the casting mold body 1 is a second parting surface 31, and the side of the casting mold body 1 close to the parting cover plate 3 is a first parting surface 12, the inner wall of the casting mold body 1 is fixedly connected with a reinforcing rib 11, the parting cover plate 3 is installed with a snap-fit ​​plate 4 that cooperates with the casting mold body 1 through a rebound mechanism 5, and the side of the casting mold body 1 away from the parting cover plate 3 is fixedly connected with two symmetrically arranged slag strips 2, the length of the slag strips 2 is equal to the length of the casting mold body 1, and a slag discharge port located between the two slag strips 2 is opened on one side of the casting mold body 1.

[0024] Specifically, through the cooperation between the casting mold body 1 and the parting cover plate 3, when pressure is applied, the sand in the cavity of the casting mold body 1 is easier to be buried, reducing the sand wrapped in the casting to produce sand holes. At the same time, a slag strip 2 with the same length as the casting mold body 1 is added to the top surface of the pouring position, which is conducive to the discharge of foam vaporization residue. After the first parting surface 12 is buried with sand, the furan resin self-hardening sand is scraped flat, and the second parting surface 31 is not coated. After the furan resin self-hardening sand is hardened, two coats of alcohol-based paint are brushed on the sand surface to make the furan resin self-hardening sand directly contact with the paint, so as to prevent foam from gasifying during punching and the paint from collapsing and rushing into the model to form defects. In subsequent processing, carbon deposition defects and sand hole defects at the early slag strip 2 do not appear, and the quality of the casting is significantly improved.

[0025] Example 2

[0026] like Figure 1 、 Figure 2 and Figure 3 As shown, the square ram casting mold, compared with the first embodiment, a parting cover plate 3 is provided on one side of the casting mold body 1 of this embodiment, and the parting cover plate 3 is installed with a snap-fit ​​plate 4 that cooperates with the casting mold body 1 through a rebound mechanism 5. The number of the snap-fit ​​plates 4 and the rebound mechanism 5 are both eight groups, and no two groups are respectively provided on one side of the parting cover plate 3 so that they surround the outer wall of the parting cover plate 3. The side of the casting mold body 1 away from the parting cover plate 3 is fixedly connected to two symmetrically arranged slag strips 2. A slag discharge port located between the two slag strips 2 is opened on one side of the casting mold body 1, and each rebound mechanism 5 includes at least one first fixed seat 51 and the second fixed seat 53, the first fixed seat 51 is fixed on the side wall of the parting cover 3 close to the snapping plate 4, the inner ring of the first fixed seat 51 is fixedly sleeved with a rotating shaft 52, the second fixed seat 53 is fixed on the side wall of the snapping plate 4 close to the parting cover 3, the second fixed seat 53 is rotatably sleeved on the outer ring of the rotating shaft 52, the rotation angle of the first fixed seat 51 and the second fixed seat 53 is 30° to 60°, an elastic member 54 is fixedly connected between the first fixed seat 51 and the second fixed seat 53, the elastic member 54 is a spring, and is sleeved on the outer ring of the rotating shaft 52, and a rounded corner 41 is provided at one end of the snapping plate 4 away from the parting cover 3.

[0027] Specifically, when the parting cover plate 3 is assembled with the casting mold body 1, the side of the casting mold body 1 will first touch the snap plate 4. Since the snap plate 4 is processed with a rounded corner 41 on the end away from the parting cover plate 3, when the snap plate 4 is squeezed, the snap plate 4 will rotate toward the side away from the parting cover plate 3 with the rotating shaft 52 as the axis. When the snap plate 4 rotates to the maximum angle, the side of the casting mold body 1 will come to the side of the snap plate 4 close to the parting cover plate 3. At this time, as the casting mold body 1 continues to be assembled and moved with the parting cover plate 3, the center of the parting cover plate 3 and the center of the casting mold body 1 will overlap. When the parting cover plate 3 and the casting mold body 1 are assembled together, the elastic part 54 will drive the snap plate 4 to rotate toward the side close to the parting cover plate 3, so that it fits together with the outer wall of the casting mold body 1.

[0028] Working principle: first, through the cooperation between the casting mold body 1 and the parting cover 3, when pressure is applied, the sand in the cavity of the casting mold body 1 is easier to be buried, reducing the sand holes caused by sand in the casting, and at the same time, a slag strip 2 with the same length as the casting mold body 1 is added to the top surface of the pouring position, which is conducive to the discharge of foam vaporization residues. After the first parting surface 12 is buried with sand, the furan resin self-hardening sand is scraped flat, and the second parting surface 31 is not coated. After the furan resin self-hardening sand is hardened, two coats of alcohol-based paint are brushed on the sand surface to make the furan resin self-hardening sand directly contact with the paint to prevent foam vaporization during punching and the paint from collapsing and rushing into the model to form defects. When the parting cover 3 is assembled with the casting mold body 1, the side of the casting mold body 1 It will first touch the snap plate 4. Since the end of the snap plate 4 away from the parting cover plate 3 is processed with a rounded corner 41, when the snap plate 4 is squeezed, the snap plate 4 will rotate with the rotating shaft 52 as the axis to the side away from the parting cover plate 3. When the snap plate 4 rotates to the maximum angle, the side of the casting mold body 1 will come to the side of the snap plate 4 close to the parting cover plate 3. At this time, the casting mold body 1 continues to be assembled and moved with the parting cover plate 3. The center of the parting cover plate 3 and the center of the casting mold body 1 will overlap. When the parting cover plate 3 and the casting mold body 1 are assembled together, the elastic part 54 will drive the snap plate 4 to rotate to the side close to the parting cover plate 3, so that it is fitted together with the outer wall of the casting mold body 1.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
