[0022] The above structure is a plastic mold with ultrasonic vibration, which uses an injection molding machine to convey the hot-melt plastic through a nozzle 12 installed in a conveying trough 11, and then the plastic enters the male mold core 5 and the female mold core 6 for molding. During the molding, the bubbles in the hot-melt plastic are eliminated by the ultrasonic vibration part 8 provided on the lower mold plate 2, and the male mold core 5, the female mold core 6 and the plastic are cooled by the cooling part 9. After cooling, the injection molding machine opens the male mold core 5 and the female mold core 6, and pushes out the molded plastic through the material return mechanism 10. Compared with the existing technology, it can remove bubbles contained in the plastic product, improve product quality, and speed up the cooling and molding time of the plastic.

[0023] like Figure 3 As shown, in some embodiments of the utility model, the ultrasonic vibration part 8 includes a plurality of through grooves 81 penetrating one of the pads 3, and a plurality of placement grooves 82 are provided on the lower template 2, each of the placement grooves 82 is aligned with the adjacent through grooves 81, and an ultrasonic vibrator 83 is placed in each of the placement grooves 82 and the through grooves 81. The ultrasonic vibrator 83 is installed and placed through the placement grooves 82 and the through grooves 81. When the ultrasonic vibrator 83 is vibrated by external power supply, the air in the hot melt plastic is gradually eliminated due to its high-frequency vibration.

[0024] like Figures 3 to 5 As shown, in some embodiments of the utility model, the cooling part 9 includes a first cooling channel 91 arranged below the upper template 1 and above the lower template 2, and a second cooling channel 92 is provided on a side of each of the pads 3 close to the bottom of the upper template 1 and the lower template 2, the first cooling channel 91 and the second cooling channel 92 are formed in an S-shaped continuous tortuosity, a slot 93 is provided on the edge of each of the first cooling channels 91, a sealing edge 94 is fixed on the periphery of each of the second cooling channels 92, and an inlet pipe 95 and an outlet pipe 96 are respectively inserted at both ends of the second cooling channel 92. When the upper template 1 and the lower template 2 are respectively fixed on the adjacent pads 3, the first cooling channel 91 and the second cooling channel 92 are merged to form a complete cooling channel, and at the same time, the sealing edge 94 and the slot 93 are plugged into each other to make the cooling channel sealed.
