[0024] Specifically, such as Figures 1-2 As shown, the blow molding body 100 has a cavity 101 inside, which is used for blow molding of thick-bottomed bottles.

[0025] Specifically, such as Figures 1-3 As shown, the base 200 is located at the bottom of the blow mold body 100 and corresponds to the position of the cavity 101. The base 200 is provided with a water inlet channel 201 and a water outlet channel 202.

[0026] Specifically, such as Figures 1-3 As shown, the bottom mold 300 is set on the top of the base 200, and the top of the bottom mold 300 is located in the cavity 101. The bottom mold 300 is provided with a water hole 301, which is connected to the water inlet channel 201 and the water outlet channel 202.

[0027] Specifically, such as Figures 1-3 As shown, the bottom of the water baffle 400 is fixed to the top of the base 200, and the top of the water baffle 400 is inserted into the water hole 301, dividing the water hole 301 into a U-shaped flow channel 401. One end of the U-shaped flow channel 401 is connected to the water inlet channel 201, and the other end of the U-shaped flow channel 401 is connected to the water outlet channel 202.

[0028] Furthermore, in this embodiment, the bottom mold 300 is made of beryllium copper, which has excellent heat transfer properties.

[0029] Furthermore, such as Figures 1-3 As shown, the top of the base 200 is provided with a mounting groove 504, and the bottom of the bottom mold 300 is set in the mounting groove 504.

[0030] Furthermore, such as Figures 1-3 As shown, a bottom cooling device for a thick-bottomed bottle after blow molding according to an embodiment of the present invention further includes: a positioning hole 501 and a positioning pin 502. The positioning hole 501 is formed at the bottom of the bottom mold 300; the positioning pin 502 passes through the base 200 and is inserted into the positioning hole 501, so that the bottom mold 300 can be positioned at the top of the base 200.

[0031] Furthermore, such as Figures 1-3 As shown, a rubber ring 503 is provided between the bottom mold 300 and the base 200 to improve the sealing and prevent water from overflowing.

[0032] Furthermore, such as Figures 1-3 As shown, the blow molding body 100 can have multiple internal chambers 101, and each chamber 101 is provided with a base 200, a bottom mold 300, and a water-separating plate 400, thereby allowing simultaneous cooling of the bottoms of multiple thick-bottomed bottles after blow molding, improving efficiency.

[0035] Cooling water is supplied through the water inlet channel 601 on the water plate 600. The cooling water enters the water inlet channel 201 on multiple bases 200 and enters one end of the U-shaped channel 401 in the corresponding bottom mold 300. It flows through the U-shaped channel 401 in the bottom mold 300, thereby allowing the bottom mold 300 to exchange heat and cool the bottom of the thick-bottomed bottle after blow molding. The cooled water after heat exchange flows out from the other end of the U-shaped channel 401 to the water outlet channel 202 on multiple bases 200, and finally is discharged from the water outlet channel 602 on the water plate 600.

[0036] Above, refer to Figures 1-3 This invention describes a bottom cooling device for a thick-bottomed bottle after blow molding, according to an embodiment of the present invention.
