Description

Technical Field

[0001] The utility model relates to the technical field of sand casting, in particular to a sand casting box closing and positioning device. Background Art

[0002] Sand casting begins with the creation of a sand mold. The mold, which contains the exterior shape of the casting, contains sand cores, which form the interior cavity or complex structure of the casting. Molten metal is poured into the sand mold, where it flows through the mold, filling the exterior shape and the interior cavity formed by the sand cores. After the metal cools and solidifies, the sand mold is disassembled and the cores removed, resulting in a casting with an internal cavity or a specific structure.

[0003] When the existing lower sand mold and the upper sand mold are combined, a positioning pin is usually required. The two ends of the positioning pin are inserted into the embedded positioning sleeves provided on the lower sand mold and the upper sand mold respectively, so as to complete the combination operation of the upper sand mold and the lower sand mold. However, the length of the existing embedded positioning sleeves is fixed. Sand molds or sand cores of different heights need to be replaced with different embedded positioning sleeves. In addition, the reinforcing ribs protruding from the embedded positioning sleeves are easily damaged during the sand falling process, thereby increasing the cost of sand casting.

[0022] The box body 1 may include an upper sand mold 10 and a lower sand mold 11 , the lower box housing 2 is arranged on the lower sand mold 11 , and a first sand hanging groove 20 is opened on the lower box housing 2 .

[0023] It can be understood that, by setting up the first sand hanging groove 20, the lower box sleeve 2 can be fixed on the lower sand mold 11, and the first sand hanging groove 20 is an annular concave setting, which facilitates the sand falling of the lower sand mold 11 and is not easy to be damaged, thereby avoiding that after the protruding reinforcement ribs are set on the lower box sleeve 2, during the sand falling process, the relevant staff hits the lower sand mold 11 with force, causing the protruding reinforcement ribs to be damaged by force, and the lower box sleeve 2 fixedly connected to the reinforcement ribs to be damaged, thereby reducing the sand casting cost of the device.

[0024] The upper casing 3 is arranged on the upper sand mold 10 , and a second sand hanging groove 30 is opened on the upper casing 3 .

[0025] It can be understood that by setting the second sand hanging groove 30, the upper box sleeve 3 can be fixed on the upper sand mold 10, and the second sand hanging groove 30 is an annular concave setting, which facilitates the sand falling of the upper sand mold 10 and is not easy to be damaged, thereby avoiding the situation where after the protruding reinforcement ribs are set on the upper box sleeve 3, during the sand falling process, the relevant staff hit the upper sand mold 10 with force, causing the protruding reinforcement ribs to be damaged by force, and the upper box sleeve 3 fixedly connected to the reinforcement ribs to be damaged, thereby reducing the sand casting cost of the device.

[0026] It should be noted that, the first sand hanging groove 20 described in this embodiment is provided with at least one on the lower box sleeve 2, and the number thereof is adjusted according to the length of the lower box sleeve 2, and the second sand hanging groove 30 is provided with at least one on the upper box sleeve 3, and the number thereof is adjusted according to the length of the upper box sleeve 3, thereby ensuring the sand mold fixing effect of the upper box sleeve 3 and the lower box sleeve 2, and ensuring the positioning accuracy of the sand mold during sand casting.

[0027] The sleeve 4 is arranged on the upper sand mold 10 , and the sleeve 4 is slidably sleeved on the upper casing 3 .

[0028] It can be understood that the sleeve 4 can be slidably mounted on the upper box sleeve 3, and the sliding distance of the upper box sleeve 3 on the sleeve 4 can be adjusted according to the upper sand mold 10 and the sand core, so that it can be suitable for sand molds and sand cores of different heights, thereby reducing the cost of sand casting.

[0029] One end of the positioning pin 5 is plugged into the lower box sleeve 2 , and the other end of the positioning pin 5 is plugged into the sleeve 4 .

[0030] It should be noted that the positioning pins 5 described in this embodiment need to be individually set according to the upper sand mold 10 and sand core of different heights, so that they can cooperate with the lower box sleeve 2, the upper box sleeve 3 and the sleeve 4 to achieve accurate positioning of the sand mold casting box.

[0031] Specifically, in the actual operation process, the relevant staff pours the sand casting material into the upper mold (not shown in the figure), and places the upper box sleeve 3 and the sleeve 4 in the upper mold to form the upper sand mold 10, and then pours the sand casting material into the lower mold (not shown in the figure), and places the lower box sleeve 2 in the lower mold to form the lower sand mold 11. The relevant staff inserts the positioning pins 5 of appropriate length into the lower box sleeve 2, and uses a crane (not shown in the figure) to lift the upper sand mold 10 so that the upper box sleeve 3 is plugged into the positioning pins 5, thereby completing the sand casting box positioning. In addition, during the sand mold falling process, the relevant staff knocks the upper sand mold 10 and the lower sand mold 11. Due to the first sand hanging groove 20 concavely opened on the upper box sleeve 3 and the second sand hanging groove 30 concavely opened on the lower box sleeve 2, the upper sand mold 10 and the lower sand mold 11 will not damage the upper box sleeve 3 and the lower box sleeve 2 when falling, thereby reducing the sand casting cost of the device.

[0034] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the positioning pin 5 is tapered.

[0035] It can be understood that by setting the conical positioning pin 5 and the top of the positioning pin 5 being conical, it is convenient for the upper box sleeve 3 and the conical positioning pin 5 to be quickly plugged and positioned after the upper sand mold 10 is lifted, avoiding the need for manual precise alignment when the positioning pins 5 with the same upper and lower diameters are plugged into the upper box sleeve 3 of the lifted upper sand mold 10.

[0036] In one embodiment of the present invention, Figure 1-Figure 3 As shown, the positioning pin 5 may include a positioning portion 50 and a guide portion 51 , the lower housing 2 and the upper housing 3 are respectively plugged into the positioning portion 50 , and the sleeve 4 is plugged into the guide portion 51 .

[0037] It should be noted that the length of the positioning portion 50 described in this embodiment is greater than the total length of the sand-hanging portions of the lower casing 2 and the upper casing 3 , thereby ensuring the precise positioning effect of the positioning pin 5 .

[0038] It should be noted that the diameter of the positioning portion 50 described in this embodiment and the gap between the upper casing 3 and the lower casing 2 are less than 1 mm, thereby ensuring the positioning accuracy of the positioning pin 5 .

[0039] In one embodiment of the present invention, Figure 1-Figure 3 As shown, a cover plate 40 is provided on the sleeve 4 .

[0040] It can be understood that the cover plate 40 provided on the sleeve 4 can prevent sand from entering the sleeve 4 during the sand casting process.
