[0024] See also Figure 1-4 As shown, a blow molding machine for producing plastic barrels includes an operating table 1 and a sealing blow molding mechanism 3. A blow molding tube 2 is provided above the operating table 1, and a sealing blow molding mechanism 3 is provided at the top of the operating table 1.

[0025] The sealing blow molding mechanism 3 includes an opening and closing component 31 and a pressure detection component 32 . The opening and closing component 31 is installed on the top of the operating table 1 , and the pressure detection component 32 is provided on the inner side of the opening and closing component 31 .

[0026] Furthermore, the opening and closing assembly 31 includes a support frame 311, an electric control push rod 312, a connecting frame 313, a mold box 314, an auxiliary support rod 315, a sealing connecting strip 316 and a sealing gasket 317. The support frame 311 is installed on the left and right sides of the top of the operating table 1, and the electric control push rod 312 is installed on the inner side of the support frame 311. The inner side of the electric control push rod 312 is fixedly connected to the connecting frame 313, and the mold box 314 is installed on the inner side of the connecting frame 313. The mold box 314 is driven to close together by the electric control push rod 312, and the mold box 314 is supported at the same time to ensure that the mold box 314 is firmly closed when blow-molding the plastic barrel.

[0027] Furthermore, auxiliary support rods 315 are installed on the upper and lower sides of the electric control push rod 312. The auxiliary support rods 315 are connected to the mold box 314 through a slot. The auxiliary support rods 315 provide auxiliary support to the mold box 314, thereby improving the stability of the mold box 314 during use.

[0028] Furthermore, a sealing connecting strip 316 is installed at the left end of the mold box 314, and a sealing gasket 317 is provided on the left surface of the mold box 314. When the mold boxes 314 are combined together, the air tightness inside the mold box 314 is improved to ensure the integrity of the plastic barrel.

[0029] Furthermore, the pressure detection component 32 includes a bottom pressure sensor 321, a side wall pressure sensor 322 and a buzzing alarm 323. The bottom end of the inner part of the mold box 314 is installed with a bottom pressure sensor 321, the inner side of the mold box 314 is installed with a side wall pressure sensor 322, and the outer side of the support frame 311 is installed with a buzzing alarm 323. The pressure sensor and the buzzing alarm 323 are electrically connected, and then the blow molding of the plastic barrel is pressure-detected through the pressure sensor. When it is detected that the blow molding pressure has not reached the predetermined threshold for a long time, the buzzing alarm 323 is used to buzz and warn, thereby ensuring that the blow molding pressure of the plastic barrel reaches the predetermined value and improving the qualified rate of the plastic barrel.

[0030] Example 2

[0031] See also Figure 1 and Figure 4 As shown, in contrast to Example 1, as another embodiment of the present invention, a cooling assembly 4 is installed on the outside of the mold box 314, and the cooling assembly 4 includes a cooling box 41, a connecting pipe 42, a cooling pipe 43 and a cooling card table 44. The cooling box 41 is installed on the inside of the operating table 1, and a connecting pipe 42 is installed on the outside of the mold box 314. The inner pipeline of the connecting pipe 42 is connected to the cooling pipe 43. The coolant in the cooling box 41 flows in the cooling pipe 43 and is cooled from the outside of the mold box 314, thereby reducing the overall temperature of the mold box 314 and improving the molding speed of the plastic barrel.

[0032] Furthermore, a cooling card platform 44 is provided on the outer surface of the mold box 314, and the cooling tube 43 is tightly fitted to the cooling card platform 44. By fitting the cooling tube 43 to the mold box 314 and the cooling card platform 44 being a hollow structure, the temperature transfer effect is improved.

[0033] Working principle: When in use, the first step is to install the device at the desired location, then connect the blank to the blow molding tube 2, and then drive the mold box 314 to close together through the electric control push rod 312, and at the same time support the mold box 314 to ensure the firmness of the mold box 314 when blow molding the plastic barrel. At the same time, the auxiliary support rod 315 provides auxiliary support to the mold box 314 to improve the stability of the mold box 314. The second step is to improve the airtightness inside the mold box 314 when the mold box 314 is combined together through the mutual cooperation between the sealing connecting strip 316 and the sealing gasket 317 to ensure the integrity of the plastic barrel. The third step is to connect the pressure sensor and the buzzing alarm 32 3 are electrically connected, and the blow molding pressure of the plastic barrel is detected by the pressure sensor. When it is detected that the blow molding pressure has not reached the predetermined threshold for a long time, a buzzing alarm 323 is used to buzz a warning to ensure that the blow molding pressure of the plastic barrel reaches the predetermined value, thereby improving the qualified rate of the plastic barrel. In the fourth step, the coolant in the cooling box 41 flows in the cooling pipe 43, and cools the mold box 314 from the outside to reduce the overall temperature of the mold box 314 and increase the molding speed of the plastic barrel. At the same time, by attaching the cooling pipe 43 to the mold box 314 and the cooling card table 44 having a hollow structure, the temperature transfer effect is improved, thus completing the use of a blow molding machine for plastic barrel production.
