It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model embodiment provides a casting mold for an automobile engine cylinder body, such as Figure 1-4 As shown, it includes a support platform 1; a casting device arranged on the support platform 1; and a cleaning device arranged next to the casting device; wherein the cleaning device includes: a group of connecting plates 2 symmetrically arranged on the inner side of the support platform 1; a screw rod 3 rotating between the two connecting plates 2; a connecting block 4 threadedly engaged on the screw rod 3, and the connecting block 4 slidingly engages with the outer wall of the support platform 1; a fan 5 arranged on the outside of the connecting block 4; an adsorption cover 6 connected to the adsorption end of the fan 5; a filter box 7 arranged on the outside of the support platform 1, and the discharge end of the fan 5 is connected to the filter box 7 through a flexible tube 22; an activated carbon filter element 8 arranged in the filter box 7.

[0023] It should be noted that, due to the problems in the existing casting process such as the difficulty in completely removing dust and debris from the mold base 11 and the insufficient stability of the mold base 11, these problems not only affect the smooth progress of the casting process, but may also lead to a decline in product quality and even cause safety hazards. In this solution, the casting process has been significantly optimized by providing a cleaning device and a fastening plate 17; the cleaning device ensures the cleanliness of the casting environment, avoids the influence of impurities on the product, and improves the surface quality and overall performance of the product; at the same time, the activated carbon filter element 8 filters the air to improve the quality of the working environment; the fastening plate 17 ensures the stability of the mold base 11 during the casting process, promotes the smooth progress of the loading and unloading processes, and improves production efficiency; these innovative designs not only improve the precision and quality of the castings, but also promote the efficiency, cleanliness and stability of the overall casting process.

[0024] Specifically, in this embodiment, the scheme mainly includes a support platform 1; a casting device and a cleaning device arranged on the support platform 1; first, according to the design requirements of the engine cylinder body, a number of sand cores 12 will be accurately assembled into the required mold cavity shape in the mold base 11; then, the mold base 11 will be transmitted to the lower position of the die head 13, ready for the injection of liquid metal; however, before the liquid metal is injected into the mold base 11, the debris generated by the sand core 12 in the mold base 11 must be thoroughly cleaned to ensure that the casting process is not disturbed by impurities; at this time, the cleaning device begins to play its role; the connecting plate 2 is symmetrically arranged on the inner side of the support platform 1, providing a stable support and rotation space for the screw rod 3; when the screw rod 3 starts to rotate, it accurately drives the connecting block 4 to slide on the outer wall of the support platform 1 through threaded cooperation; this design enables the connecting block 4 to move freely along the support platform 1, thereby driving the fan 5 to move to the specific position where dust cleaning is required;

[0025] Once the fan 5 reaches the designated position, it starts; the adsorption end of the fan 5 generates a strong suction force through the adsorption hood 6, and quickly sucks in the dust and debris generated in the mold base 11; these impurities are then transported to the filter box 7 by the fan 5 through its flexible tube 22; in the filter box 7, the activated carbon filter element 8 can effectively filter the inhaled air, trap dust and impurities on the filter element, and only allow clean air to be discharged through the filter box 7; this filtering mechanism not only ensures the cleanliness of the casting environment, but also improves the casting quality and efficiency.

[0026] In a further preferred embodiment of the present invention, Figure 1 As shown, the casting device includes: a receiving platform 9 arranged on the outside of the support platform 1, and the receiving platform 9 is vertically distributed with the support platform 1; a material transfer plate 10 sliding on the support platform 1; a mold base 11 arranged on the material transfer plate 10; and a plurality of sand cores 12 arranged in the mold base 11.

[0027] In this embodiment, this design allows the mold base 11 to be conveniently transferred to or removed from the casting work area to achieve an efficient casting process. Inside the mold base 11, a plurality of sand cores 12 are assembled into the required mold cavity shape, ensuring that the metal can flow and solidify in a predetermined shape during the casting process.

[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the casting device also includes: a die head 13 sliding on the upper position of the support platform 1; a driving cylinder 14 arranged on the top of the support platform 1, and the output end of the driving cylinder 14 is fixedly connected to the end key of the die head 13.

[0029] In this embodiment, during the casting process, the driving cylinder 14 pushes the die head 13 up or down to a suitable position to ensure that the die head 13 is accurately pressed together with the die base 11 .

[0030] In a further preferred embodiment of the present invention, Figure 1 As shown, vertical plates 15 are provided on both sides of the upper surface of the support platform 1, electric push rods 16 are provided on the opposite sides of the two vertical plates 15, and fastening plates 17 are provided at the output ends of the two electric push rods 16, and the two fastening plates 17 are slidably matched with the support platform 1.

[0031] In this embodiment, during the processing when the mold base 11 needs to be fixed, the electric push rods 16 on both sides are synchronously extended and retracted to push the fastening plate 17 closer to the mold base 11 until the fastening plate 17 is in close contact with the mold base 11 and sufficient fixing force is applied, thereby ensuring that the mold base 11 will not be displaced during the processing; when the processing is completed, the electric push rods 16 are extended and retracted again, so that the fastening plate 17 loosens the mold base 11, thereby facilitating the removal of the mold base 11 and the start of the next processing cycle.

[0032] In a further preferred embodiment of the present invention, Figure 1 As shown, a first motor 18 is disposed on the outer side of the connecting plate 2 , and an output end of the first motor 18 is fixedly connected to an end key of the screw rod 3 .

[0033] In this embodiment, the rotational movement of the lead screw 3 is converted into a linear displacement of the connecting block 4 by the drive of the first motor 18 , thereby achieving precise adjustment and control of the position of the connecting block 4 .

[0034] In a further preferred embodiment of the present invention, Figure 3As shown, a screw rod 19 is rotatably engaged inside the receiving platform 9, and a nut block 20 is threadedly engaged on the screw rod 19. The nut block 20 extends to the upper position of the receiving platform 9 and is connected to the bottom side of the material transfer plate 10. A second motor 21 is provided on the end side of the receiving platform 9, and the output end of the second motor 21 is fixedly connected to the end key of the screw rod 19.

[0035] In this embodiment, the second motor 21 drives the screw 19 to rotate, thereby realizing the synchronous movement of the nut block 20 that cooperates with the screw 19. Since the nut block 20 is connected to the transfer plate 10, when the nut block 20 moves, it can drive the transfer plate 10 to move synchronously. Through this mechanism, the loading and unloading processes of the mold base 11 can be realized.

[0036] Working principle: First, a number of sand cores 12 are precisely assembled into the required cavity shape in the mold base 11, in order to ensure that the metal can flow and solidify in the predetermined shape during the casting process; this step is crucial, as it lays the foundation for casting;

[0037] Next, the mold base 11 will be transferred to the designated position to prepare for the injection of liquid metal; during this process, the second motor 21 starts to work and drives the screw 19 to rotate; since the screw 19 cooperates with the nut block 20, the synchronous movement of the nut block 20 is realized; and because the nut block 20 is connected to the material transfer plate 10, when the nut block 20 moves, the material transfer plate 10 also moves synchronously; this mechanism ensures that the loading and unloading processes of the mold base 11 can be carried out smoothly;

[0038] At the same time, the electric push rods 16 on both sides will be extended and retracted synchronously, pushing the fastening plate 17 to approach the mold base 11 until the fastening plate 17 is in close contact with the mold base 11 and exerts sufficient fixing force; in this way, the mold base 11 can remain stable during the processing and will not be displaced;

[0039] However, before the liquid metal is injected into the mold base 11, the debris generated by the sand core 12 in the mold base 11 must be thoroughly cleaned; at this time, the dust cleaning device begins to play its key role; the connecting plate 2 is symmetrically arranged on the inner side of the support platform 1, providing a stable support and rotation space for the screw rod 3; the first motor 18 drives the screw rod 3 to rotate; the screw rod 3 drives the connecting block 4 to slide on the outer wall of the support platform 1 accurately through the threaded fit, thereby driving the fan 5 to move to the specific position where dust cleaning is required;

[0040] Once the fan 5 reaches the designated position, it will start, and generate strong suction force through the fan 5, so that the dust and debris generated in the mold base 11 are quickly sucked in through the adsorption cover 6, and transported to the filter box 7 through the discharge end; in the filter box 7, the activated carbon filter element 8 can effectively filter the dust and impurities in the air, ensuring that only clean air is discharged;

[0041] After the dust cleaning process is completed, the mold base 11 will be transferred to the casting work area; during the casting process, the driving cylinder 14 plays an important role, which pushes the die head 13 up or down to a suitable position to ensure that the die head 13 reaches an accurate pressing state with the mold base 11.
