[0024] like Figure 1~Figure 4 The bottom mold structure with a built-in cooling seat shown includes: a base 1, a cooling seat 3 and a bottom mold insert 2. The top surface of the base 1 is concavely provided with a first positioning groove 11 corresponding to the bottom of the bottom mold insert 2. The bottom mold insert 2 is arranged on the first positioning groove 11, which is convenient for assembly and has high precision. In this embodiment, a stepped hole 16 pointing upward to the bottom mold insert 2 is arranged at the bottom of the base 1, and a screw 4 connected to the bottom mold insert 2 is arranged in the stepped hole 16 to ensure the stability of the structure.

[0025] like Figure 5~Figure 6 As shown, the cooling seat 3 includes a bottom plate 31 and a vertical pipe 32. The first positioning groove 11 is concavely provided with a second positioning groove 12 corresponding to the bottom plate 31. The bottom plate 31 is arranged in the second positioning groove 12 for precise positioning. A cooling cavity 21 is concavely provided at the bottom of the bottom mold insert 2, which can reduce its own weight and facilitate ventilation and heat dissipation inside the bottom mold insert 2.

[0026] like Figure 4 As shown, the stepped hole 16 is located outside the second positioning groove 12 , and the chassis 31 is small in size and does not affect the installation of the screw 4 .

[0027] The riser 32 is arranged on the chassis 31 and extends upward into the cooling cavity 21. In this embodiment, the chassis 31 and the riser 32 adopt an integrated steel structure, and the riser 32 is fixed by the chassis 31. Figure 3 As shown, the edge of the base 1 is provided with an exhaust hole 14 extending to the edge of the second positioning groove 12, and the top surface of the chassis 31 is concavely provided with an exhaust groove 33 connecting the cooling cavity 21 and the exhaust hole 14, which is beneficial to the discharge of the airflow in the cooling cavity 21 and improves the ventilation and heat dissipation effect.
