Description

Technical Field

[0001] The utility model relates to casting equipment, in particular to a casting mold. Background Art

[0002] A prior patent with the authorized announcement number CN216028066U by the applicant discloses a chain casting machine, which includes an annular conveyor belt, a pouring device, and a conveying driving device capable of driving the annular conveyor belt to rotate. A plurality of molds are evenly distributed on the annular conveyor belt, and a pouring and forming groove is provided on the upper surface of the mold; the annular conveyor belt has a forward running section running from front to back and a return running section running from back to front, and the forward running section of the annular conveyor belt is above its return running section; the front part of the forward running section is provided with a pouring section that gradually slopes upward from front to back, and the pouring device is arranged above the pouring section; a lapping piece is provided on the front side edge of each mold; between two adjacent molds on the pouring section, the lapping piece of the rear mold lapped on the upper side of the rear side edge of the front mold. On the pouring section, since the lapping piece of the rear mold lapped on the upper side of the rear side edge of the front mold, the lapping piece blocks the gap between two adjacent molds; since the pouring section gradually slopes upward from front to back, the molds on the pouring section also gradually slope upward from front to back, and the lapping piece of the rear mold plays a role in guiding the flow. When the pouring device injects high-temperature molten iron into the mold on the pouring section, the high-temperature molten iron overflowing from the rear mold flows down from top to bottom along the lapping piece into the front mold, which can reduce the leakage of molten iron into the gap between two adjacent molds after the mold is deformed, prevent the molten iron from dripping onto other components of the casting machine, play a role in protecting other components of the casting machine, and ensure the normal operation of the casting machine. However, as Figure 1 shown, there will still be a gap 01 (the gap width is about 0.5 - 0.7 millimeters) between the lapping piece of the rear mold and the upper side of the rear side edge of the front mold between two adjacent molds on the pouring section, and in actual production, when the high-temperature molten iron flows into the front mold, there will be a certain backwash force. Therefore, a small amount of molten iron will still leak from the gap 01 between the lapping piece of the rear mold and the upper side of the rear side edge of the front mold. Summary of the Invention

[0003] The problem to be solved by the utility model is to provide a casting mold that can prevent molten iron from leaking into the gap between two adjacent casting molds, protect other components of the casting machine, and ensure the normal operation of the casting machine.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is as follows:

[0005] A casting mold, comprising a mold body. A casting forming groove is provided on the upper surface of the mold body. A lapping piece is provided on the front side edge of the mold body, and a lapping piece mating portion is provided on the rear side edge of the mold body. It is characterized in that: a strip-shaped baffle is provided on the upper surface of the mold body, and each casting forming groove is located on the front side of the strip-shaped baffle, and the lapping piece mating portion is located on the rear side of the strip-shaped baffle.

[0006] The height of the above-mentioned strip-shaped baffle is higher than the upper surface of the mold body and the upper surface of the lapping piece mating portion, separating each casting forming groove from the lapping piece mating portion.

[0007] The above-mentioned casting mold can be used in a chain casting machine. For example: the chain casting machine includes an endless conveyor belt, a pouring device, and a conveying driving device capable of driving the endless conveyor belt to rotate. A plurality of casting molds are evenly distributed on the endless conveyor belt; the endless conveyor belt has a forward running section running from front to back and a return running section running from back to front, and the forward running section of the endless conveyor belt is located above its return running section; the front part of the forward running section is provided with a pouring section gradually sloping upward from front to back, and the pouring device is arranged above the pouring section; between two adjacent casting molds on the pouring section, the lapping piece of the rear casting mold overlaps on the upper side of the lapping piece mating portion of the front casting mold. Since the strip-shaped baffle of the front casting mold separates its respective casting forming grooves from the lapping piece mating portion, during the pouring process, even if the molten iron in each casting forming groove of the front casting mold overflows the notch of the casting forming groove, the overflowing molten iron will be blocked by the strip-shaped baffle and cannot leak from the gap behind the strip-shaped baffle (i.e., the gap between the lapping piece of the rear mold and the upper side of the lapping piece mating portion of the front mold), thereby more effectively preventing the molten iron from leaking and dripping onto other components of the casting machine, avoiding failures of other components of the casting machine, and ensuring the normal operation of the casting machine.

[0008] In a preferred solution, the lower side edge of the strip-shaped baffle is integrally connected to the upper surface of the mold body.

[0009] In another preferred solution, the strip-shaped baffle is detachably installed on the upper surface of the mold body. When the strip-shaped baffle needs to be replaced due to long-term use, the lower side of the strip-shaped baffle can be detached from the mold body, facilitating the replacement of the strip-shaped baffle without disassembling the entire mold body, saving time and labor.

[0010] In a further preferred solution, the lower side edge of the strip-shaped baffle can be inserted and installed on the upper surface of the mold body. The lower side of the strip-shaped baffle and the mold body are designed as an insertion structure, facilitating the installation of the strip-shaped baffle onto the mold body and improving the installation efficiency.

[0011] In a further preferred embodiment, a strip-shaped slot is provided on the upper surface of the mold body, and a strip-shaped insert is provided at the bottom of the strip-shaped baffle plate to match the slot. The strip-shaped insert is inserted into the slot. The matching design of the strip-shaped slot and the insert ensures a tight connection between the strip-shaped baffle plate and the mold body, preventing loosening and improving the stability of the strip-shaped baffle plate. The strip-shaped slot typically extends in a left-right direction.

[0012] In a further preferred embodiment, the cross-sectional shape of the strip-shaped insert is dovetail-shaped, and the cross-sectional shape of the strip-shaped slot is dovetail-shaped.

[0013] In another further preferred embodiment, a plurality of screw holes are provided on the bottom surface of the strip baffle, and locking screws are installed in the screw holes. A plurality of through holes corresponding to the screw holes are provided on the mold body, and the rod of the locking screw passes through the corresponding through holes. The head of the locking screw and the bottom surface of the strip baffle jointly clamp the mold body.

[0014] In a preferred embodiment, a shielding strip is provided on the front side of the top of the overlapping piece, and the height of the shielding strip is higher than the top of the strip baffle. When the overlapping piece of the rear casting mold overlaps the upper side of the mating portion of the overlapping piece of the front casting mold, the shielding strip on the overlapping piece of the rear casting mold is located above the top of the strip baffle of the front casting mold. The shielding strip of the rear casting mold covers the top of the strip baffle of the front casting mold. During the pouring process, overflowing molten iron will be blocked by the shielding strip and cannot leak through the gap between the front side of the overlapping piece of the rear casting mold and the back side of the strip baffle of the front casting mold, further preventing molten iron leakage.

[0015] In a preferred embodiment, the strip-shaped baffle and the upper surface of the mold body are perpendicular to each other.

[0016] In a preferred embodiment, the strip baffles are made of steel, copper, copper alloy, or graphite. Since steel, copper, copper alloy, or graphite all have excellent thermal conductivity, mechanical strength, and corrosion resistance, they can more effectively conduct heat through the strip baffles, preventing deformation or damage due to overheating. They can also withstand corrosion from high-temperature molten iron, thereby extending the service life of the strip baffles.

[0017] In a preferred embodiment, a retaining wall is provided on both the left and right edges of the mold body, and the height of the retaining wall is higher than the upper surface of the mold body.

[0018] The casting mold also includes two support plates, one at each end of the mold body. The two support plates are used to connect the casting mold to a mold conveying mechanism (for example, the mold conveying mechanism includes two side-by-side endless chains, and the two support plates are connected to the two endless chains respectively).

[0019] Compared with the prior art, the present invention has the following advantages:

[0020] The strip baffle on this casting mold can block the overflowing molten iron, preventing it from leaking into the gap in front of the strip baffle and preventing the overflowing molten iron droplets from falling onto other components of the casting machine, avoiding malfunctions of other components of the casting machine and ensuring the normal operation of the casting machine.

[0029] The present utility model will be specifically described below in conjunction with the drawings and specific embodiments.

[0030] Embodiment 1, as Figure 2-4 shown, the casting mold in this embodiment includes a mold body 1. A casting forming groove 11 is provided on the upper surface of the mold body 1. A lapping piece 12 is provided on the front side edge of the mold body 1. A lapping piece mating portion 13 is provided on the rear side edge of the mold body 1. A strip baffle 14 is provided on the upper surface of the mold body 1. Each casting forming groove 11 is located in front of the strip baffle 14, and the lapping piece mating portion 13 is located behind the strip baffle 14.

[0031] The height of the above-mentioned strip baffle 14 is higher than the upper surface of the mold body 1 and the upper surface of the lapping piece mating portion 13, separating each casting forming groove 11 from the lapping piece mating portion 13.

[0032] The above-mentioned casting mold can be used in a chain casting machine, for example: the chain casting machine includes an endless conveyor belt, a pouring device and a conveying drive device capable of driving the endless conveyor belt to rotate, and a plurality of casting molds are evenly distributed on the endless conveyor belt; the endless conveyor belt has a forward section running from front to back and a return section running from back to front, and the forward section of the endless conveyor belt is located above its return section; the front part of the forward section is provided with a pouring section gradually inclined upward from front to back, and the pouring device is arranged above the pouring section; between two adjacent casting molds on the pouring section, the overlap plate 12 of the rear casting mold overlaps the upper side of the overlap plate matching part 13 of the front casting mold. Since the strip baffle 14 of the front casting mold separates its various casting molding grooves 11 from the overlapping piece matching part 13, during the casting process, even if the molten iron in the various casting molding grooves 11 of the front casting mold overflows the notch of the casting molding groove 11, the overflowed molten iron will be blocked by the strip baffle 14 and cannot leak from the gap on the rear side of the strip baffle 14 (that is, the gap between the overlapping piece 12 of the rear mold and the upper side of the overlapping piece matching part 13 of the front mold), thereby more effectively preventing the molten iron from leaking and dripping onto other parts of the casting machine, avoiding malfunction of other parts of the casting machine, and ensuring the normal operation of the casting machine.

[0033] The lower edge of the strip baffle 14 is integrally connected to the upper surface of the mold body 1 .

[0034] The strip baffle 14 and the upper surface of the mold body 1 are perpendicular to each other.

[0035] The strip baffles 14 are made of steel, copper, copper alloy, or graphite. Because steel, copper, copper alloy, or graphite all have excellent thermal conductivity, mechanical strength, and corrosion resistance, they can more effectively conduct heat through the strip baffles 14, preventing deformation or damage from overheating. They also withstand corrosion from high-temperature molten iron, extending the service life of the strip baffles 14.

[0036] A protective wall 15 is provided on both the left and right edges of the mold body 1 . The height of the protective wall 15 is higher than the upper surface of the mold body 1 .

[0037] The casting mold further includes two support plates 2, which are disposed at the left and right ends of the mold body 1. The two support plates 2 are used to connect the casting mold to a mold conveying mechanism (for example, the mold conveying mechanism includes two side-by-side endless chains, and the two support plates 2 are respectively connected to the two endless chains).

[0038] Example 2, as Figure 5-6 As shown, the difference between this embodiment and embodiment 1 is:

[0039] The strip-shaped baffle 14 is detachably installed on the upper surface of the mold body 1. When the strip-shaped baffle 14 needs to be replaced due to long-term use, the lower side of the strip-shaped baffle 14 can be detached from the mold body 1, which is convenient for replacing the strip-shaped baffle 14 without disassembling the entire mold body 1, saving time and labor.

[0040] The lower side edge of the strip-shaped baffle 14 can be inserted and installed on the upper surface of the mold body 1. Designing the lower side of the strip-shaped baffle 14 and the mold body 1 into an insertion structure facilitates the installation of the strip-shaped baffle 14 onto the mold body 1 and improves the installation efficiency.

[0041] A strip-shaped slot 16 is provided on the upper surface of the mold body 1, and a strip-shaped insertion block 141 matching the strip-shaped slot 16 is provided at the bottom of the strip-shaped baffle 14. The strip-shaped insertion block 141 is inserted into the strip-shaped slot 16. The matching design of the strip-shaped slot 16 and the strip-shaped insertion block 141 ensures the tight connection between the strip-shaped baffle 14 and the mold body 1, prevents loosening, and improves the stability of the strip-shaped baffle 14. The above-mentioned strip-shaped slot 16 generally extends in the left-right direction.

[0042] The cross-sectional shape of the strip-shaped insertion block 141 is dovetail-shaped, and the cross-sectional shape of the strip-shaped slot 16 is dovetail-shaped.

[0043] Example 3, as Figure 7 shown, the difference between this example and Example 2 is that:

[0044] A plurality of screw holes 142 are provided on the bottom surface of the strip-shaped baffle 14, and locking screws 143 are installed in the screw holes 142. A plurality of through holes 17 corresponding to the screw holes 142 are provided on the mold body 1. The rod portion of the locking screw 143 passes through the corresponding through hole 17, and the head of the locking screw 143 and the bottom surface of the strip-shaped baffle 14 clamp the mold body 1 together.

[0045] Example 4, as Figure 8 shown, the difference between this example and Example 2 is that:

[0046] A shielding strip 18 is provided on the front side of the top of the overlapping piece 12, and the height of the shielding strip 18 is higher than the top of the strip-shaped baffle 14. When the overlapping piece 12 of the rear casting mold overlaps on the upper side of the overlapping piece mating portion 13 of the front casting mold, the shielding strip 18 on the overlapping piece 12 of the rear casting mold is above the top of the strip-shaped baffle 14 of the front casting mold, and the shielding strip 18 of the rear casting mold covers the top of the strip-shaped baffle 14 of the front casting mold. During the pouring process, the overflowing molten iron will be blocked by the shielding strip 18 and cannot leak through the gap between the front side of the overlapping piece 12 of the rear casting mold and the rear side of the strip-shaped baffle 14 of the front casting mold, further preventing the leakage of molten iron.

[0047] In addition, it should be noted that for the specific embodiments described in this specification, the names of their respective parts and the like can be different. Any equivalent or simple changes made according to the structure, features, and principles described in the inventive concept of this utility model are included within the protection scope of this utility model patent.
