[0019] like Figure 1-2 As shown, a cylinder lower core mold with a core-binding mechanism includes a base 1 and a boss 12. The top surface of the base 1 is fixedly provided with the boss 12, and the top surface of the boss 12 is provided with a supporting assembly for supporting the sand core. The top of the base 1 is provided with core-binding assemblies at positions on both sides of the boss 12; the core-binding assembly includes a cylinder 7, an air-binding plate 8 and an air-binding needle 9, a bracket 6 is fixedly connected to the base 1, and the cylinder 7 is fixedly installed on the bracket 6 for driving the air-binding plate 8 to translate, and a plurality of air-binding needles 9 are fixedly provided on the side of the air-binding plate 8 facing the sand core.

[0020] Specifically, the supporting assembly supports and positions the sand core, and the cylinder 7 is started. The movement of the cylinder 7 drives the two air piercing plates 8 to approach the sand core placed on the supporting assembly. The air piercing needles 9 on the air piercing plates 8 are synchronously driven to move, and the air piercing needles 9 are inserted into the sand core, thereby piercing the sand core and making the sand core have ventilation function.

[0021] Preferably, the supporting assembly includes a first limiting rod 2, a first supporting seat 3, a second supporting seat 4, a center supporting seat 5 and a second limiting rod 11. The first limiting rod 2 and the first supporting seat 3 are arranged at the four corners of the boss 12. The center supporting seat 5 is fixedly arranged in the middle of the top surface of the boss 12. The second supporting seat 4 is fixedly arranged at the positions at both ends of the center supporting seat 5 on the top surface of the boss 12. The second limiting rod 11 is fixedly arranged in the middle of the side of the boss 12 close to the core-binding assembly.

[0022] Specifically, the first limiting rod 2 and the second limiting rod 11 position the sand core so that the sand core is in a correct position, and the first supporting seat 3, the second supporting seat 4, and the central supporting seat 5 support the sand core.

[0023] Preferably, the core-binding assembly also includes a linear bearing 10 for connecting the air-binding plate 8 and the bracket 6.

[0024] Specifically, the optical axis of the linear bearing 10 is fixedly connected to the air-binding plate 8 , and the bearing sleeve of the linear bearing 10 is fixedly connected to the bracket 6 , thereby ensuring the stability of the translation of the air-binding plate 8 .

[0025] Preferably, the two groups of core-binding assemblies are arranged opposite to each other, and the axial direction of the bracket 6 is arranged along the horizontal direction.

[0026] Specifically, the two groups of core-binding assemblies can synchronously insert the air-binding needles 9 on the air-binding plate 8 into the sand core.

[0027] Preferably, the tip of the air puncture needle 9 faces the sand core to facilitate puncturing the sand core.

[0028] Preferably, the first limiting rod 2 and the second limiting rod 11 are both in the shape of elongated strips, and the length direction is perpendicular to the boss 12, and the first supporting seat 3 and the second supporting seat 4 both have elongated protrusions.

[0029] Specifically, the long strips of the first limiting rod 2 and the second limiting rod 11 center the sand core when placed, and the first supporting seat 3 and the second supporting seat 4 simultaneously position the sand core through the long strip-shaped protrusions while supporting the sand core, so that the sand core is placed in the correct position.

[0030] In the above structure, the sand core is placed on the first support seat 3, the second support seat 4 and the center support seat 5. At the same time, the first limit rod 2 and the second limit rod 11 cooperate with the first support seat 3, the second support seat 4 and the center support seat 5 to position the sand core, and then the cylinder 7 is started. The movement of the cylinder 7 drives the two air piercing plates 8 to approach the sand core, and the air piercing needle 9 on the air piercing plate 8 is inserted into the sand core, thereby piercing the sand core, so that the sand core has a ventilation function, ensuring that the gas generated during the casting process can be discharged smoothly, reducing the occurrence of waste. After the core piercing is completed, the cylinder 7 is started to move and drive the two air piercing plates 8 away from the sand core, and then the air piercing needle 9 is pulled out from the sand core.

[0031] The above shows and describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present application.
