[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figure 1 、 2As shown in Figures 3 and 4, the utility model provides a technical solution: a rubber-coated structure for an inflatable toy mouth, comprising: an upper mold 1 with a glue injection port on the top, a glue injection pipe inside the upper mold 1, and a mold cavity 3 for secondary rubber coating at the bottom of the upper mold 1; a lower mold 2 is placed below the upper mold 1, and a storage cavity 5 corresponding to the mold cavity 3 is opened in the middle of the bottom of the lower mold 2, a rubber sealing plug 11 is installed above the storage cavity 5, and a negative pressure part is provided at the bottom of the storage cavity 5, which makes the toy mouth swell in the storage cavity 5, and the mouth of the toy mouth is sealed with a silicone sealing plug, and then the outlet is completely sealed by secondary rubber coating of the mold cavity 3.

[0022] It should be noted that, the utility model places the inflatable toy mouth in the storage cavity 5, and then draws the storage cavity 5 into negative pressure through negative pressure merging. Under the action of air pressure, the inflatable toy mouth expands in the storage cavity 5 and the outer wall fits with the interior of the storage cavity 5, so that the glue sealing plug 11 is placed at the opening of the inflatable toy mouth, and then the upper mold 1 and the lower mold 2 are combined, and silicone is injected into the mold cavity 3 so that the silicone seals the inflatable toy mouth and the glue sealing plug 11. After cooling and forming, the upper mold 1 and the lower mold 2 are separated, and then the negative pressure at the bottom of the storage cavity 5 is cancelled, and air is blown into the storage cavity 5 through the exhaust pipe 7 to push out the inflatable toy mouth after sealing.

[0023] See also Figure 2 As shown, a positioning block 10 is fixed to the center position of the bottom of the upper mold 1, a positioning groove 9 is provided on the top of the lower mold 2 to cooperate with the positioning block 10, guide rods 12 are fixed to the four corners of the bottom of the upper mold 1, and a positioning hole corresponding to the guide rod 12 is provided on the top of the upper mold 1. A limiting plug-in block 14 is fixed to the outer side of the upper mold 1, and a limiting slot 13 is provided on the outer side of the lower mold 2 to cooperate with the limiting plug-in block 14.

[0024] It should be noted that when the upper mold 1 and the lower mold 2 of the utility model are closed, the guide rod 12 is inserted into the positioning hole at the top of the lower mold 2, and the limit plug 14 is inserted into the middle of the limit slot 13, so as to achieve precise positioning, so that the mold cavity 3 corresponds to the position of the positioning boss 4, and the guide rod 12 cooperates with the corresponding positioning hole to ensure that the upper mold 1 can be smoothly aligned when the mold is closed to avoid deviation; the cooperation between the limit plug 14 and the limit slot 13 provides additional positioning protection to prevent the mold from accidentally moving during operation.

[0025] See also Figure 3 As shown, a positioning boss 4 cooperating with the mold cavity 3 is provided on the top of the lower mold 2, and the receiving cavity 5 is located in the middle of the positioning boss 4. An exhaust cavity 6 is fixed inside the lower mold 2 and at the bottom of the receiving cavity 5.

[0026] It should be noted that the vacuum chamber 6 of the present invention is fixedly connected to the bottom of the storage chamber 5, and the two form a cavity that is compatible with the inflatable toy mouth. When negative pressure is pumped at the bottom of the vacuum chamber 6, the inflatable toy mouth fits with the cavity composed of the storage chamber 5 and the vacuum chamber 6 under the action of suction, and expands and deforms to fill the entire cavity, so that the inflatable toy mouth is in an expanded state before being sealed.

[0027] See also Figure 3 、 4 As shown, the negative pressure part includes an exhaust pipe 7 fixedly connected to the bottom of the exhaust chamber 6, and a valve 8 is fixedly connected to the end of the exhaust pipe 7, which is connected to the negative pressure device.

[0028] It should be noted that the negative pressure equipment of the present invention is a vacuum pump, which is connected to the valve 8 through the solenoid valve reversing valve. The vacuum pump forms a negative pressure inside the exhaust chamber 6 through the valve 8 and the exhaust pipe 7, thereby drawing the inflatable mouthpiece into an expanded state before sealing. In addition, the solenoid reversing valve is connected to an external air source, which can inflate the exhaust pipe 7, thereby demolding the inflatable mouthpiece after sealing is completed.
