[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 2-Figure 4The utility model provides an embodiment: a cylinder head casting mold for a diesel engine, comprising a fixed platform 1 and a base 2, a lower mold 3 is arranged on the top of the fixed platform 1, a mold body 4 is arranged on the top of the lower mold 3, an upper mold 5 is slidably connected to the top of the mold body 4, a connecting frame 6 is fixedly connected to one side of the mold body 4, a fixed column 7 is slidably connected inside the connecting frame 6, a fixing rod 8 is fixedly connected to the bottom of the upper mold 5, the fixing rod 8 is slidably connected inside the connecting frame 6, a clamping rod 9 is fixedly connected to the top of the lower mold 3, the clamping rod 9 is slidably connected inside the connecting frame 6, a clamping block 11 is slidably connected inside the connecting frame 6, a spring 10 is arranged at one end of the fixing column 7, one end of the spring 10 is fixedly connected to one side of the clamping block 11, one side of the clamping block 11 is fixedly connected to a connecting plate 12, one side of the connecting plate 12 is fixedly connected to a sliding block 13, a limiting component is arranged on one side of the fixing rod 8, the limiting component includes a limiting block 14, one side of the limiting block 14 is fixedly connected to one side of the fixing rod 8, and the limiting block 14 contacts the sliding block 13.

[0025] Specifically, when the mold needs to be disassembled, the upper mold 5 needs to be moved upward first. This movement process will drive the fixing rod 8 fixedly connected at the bottom to move inside the connecting frame 6. The movement of the fixing rod 8 further drives the movement of the limit block 14 fixedly connected on one side, and during the movement, the limit block 14 contacts the slider 13 and applies an extrusion force to it. At this time, the force applied to the slider 13 causes it to move toward the inside of the connecting frame 6, and the movement of the slider 13 drives the movement of the connecting plate 12 fixedly connected on one side. After the connecting plate 12 is subjected to force, it drives the clamping block 11 fixedly connected on one side to slide toward the inside of the connecting frame 6. This sliding process causes the clamping rod 9 engaged with the clamping block 11 to be loosened, thereby realizing the disassembly of the mold and achieving the effect of quick disassembly and assembly of the mold.

[0026] Reference Figure 1 and Figure 5 A fixed plate 25 is fixedly connected to the top of the base 2, a motor 15 is fixedly connected to the top of the fixed plate 25, a rotating wheel 16 is fixedly connected to the output end of the motor 15, two left-right symmetrical fixed frames 17 are fixedly connected to the top of the base 2, the rotating wheel 16 is rotatably connected to the inside of one of the fixed frames 17, and a rotating wheel 2 18 is rotatably connected to the inside of the other fixed frame 17, and a synchronous belt 19 is provided on the outer wall of the rotating wheel 2 18 and the rotating wheel 1 16.

[0027] Specifically, when using the mold, first place the mold on the surface of the fixed table 1. Next, the output end of the motor 15 drives the rotating wheel 16 to start rotating. The rotating wheel 16 rotates synchronously with the rotating wheel 2 18 through the synchronous belt 19 provided on the outer wall of the rotating wheel 16, thereby achieving the driving effect.

[0028] Reference Figure 1 and Figure 5A guide rail 21 is fixedly connected to the top of the base 2, a first slide 20 is fixedly connected to one side of the synchronous belt 19, the first slide 20 is internally slidably connected to the outer wall of the guide rail 21, a second slide 24 is fixedly connected to the other side of the synchronous belt 19, a guide rail 23 is fixedly connected to the top of the base 2, the second slide 24 is internally slidably connected to the outer wall of the guide rail 23, and a positioning rod 22 is fixedly connected to the top of the second slide 24 and the first slide 20.

[0029] Specifically, the force exerted on the synchronous belt 19 guides the first slide 20 fixedly connected on one side to move on the outer wall of the guide rail 1 21, and also drives the second slide 24 fixedly connected on the other side to move on the outer wall of the guide rail 2 23. Through the movement of the first slide 20 and the second slide 24, the positioning rod 22 fixedly connected at the top also moves accordingly. In this way, the positioning rod 22 can quickly and accurately position the mold, achieving the effect of rapid positioning.

[0030] Working principle: when the mold needs to be disassembled, the upper mold 5 is first moved upward. The upper mold 5 is forced to drive the fixing rod 8 fixedly connected at the bottom to move inside the connecting frame 6. The fixing rod 8 is forced to drive the limit block 14 fixedly connected on one side to move. During the movement, the limit block 14 contacts the slider 13 to squeeze it. At this time, the slider 13 is forced to move inside the connecting frame 6. The slider 13 is forced to drive the connecting plate 12 fixedly connected on one side to move. The connecting plate 12 is forced to drive the card block 11 fixedly connected on one side to slide inside the connecting frame 6, so that the locking rod 9 engaged with the card block 11 is released, thereby the mold is disassembled, achieving the goal of the mold being able to be quickly disassembled. The mold is used to achieve the effect of quick disassembly and assembly. When using the mold, first place the mold on the upper surface of the fixed table 1, and then drive the rotating wheel 16 to rotate through the output end of the motor 15. The rotating wheel 16 drives the rotating wheel 2 18 to rotate synchronously through the synchronous belt 19 arranged on the outer wall. At this time, the synchronous belt 19 is forced to drive the first slide 20 fixedly connected on one side to move on the outer wall of the guide rail 1 21. At the same time, the synchronous belt 19 also drives the second slide 24 fixedly connected on the other side to move on the outer wall of the guide rail 2 23. The movement of the first slide 20 and the second slide 24 drives the positioning rod 22 fixedly connected on the top to move, so that the positioning rod 22 positions the mold, achieving the effect of quick positioning.
