[0026] Please see Figure 1-4 A silicone rubber thermoforming anti-displacement positioning mold includes a mounting plate 1 and a mounting plate 2, which are used to install a lower template 5 and an upper template 4, respectively. Mounting plate 2 is positioned directly above mounting plate 1, and an auxiliary rod 3 is installed at the connection between mounting plate 2 and mounting plate 1. The auxiliary rod 3 assists in the up-and-down movement of the upper template 4. The lower template 5 is bolted to the upper part of mounting plate 1, and the upper template 4 is bolted to the lower part of mounting plate 2. The lower template 5 and the upper template 4 are used for silicone rubber thermoforming. Notches 1 8 and 2 9 are provided at the corners of the upper template 4 and the lower template 5, respectively. Notches 1 8 and 2 9 are used to install a positioning pin 6 and a positioning sleeve 7, respectively. The positioning pin 6 is installed below notch 1 8, and the positioning sleeve 7 is installed above notch 2 9. The positioning pin 6 and the positioning sleeve 7 are used to position the lower template 5 and the upper template 4. The lower template 5 has a product groove 10 on its inner side and a slot 11 on its upper part. The upper template 4 has a product groove 12 on its inner side. Product grooves 10 and 12 are used to fill the material for subsequent thermoforming. An anti-slip block 13 is fixedly connected to the lower part of the upper template 4. The anti-slip block 13 and the slot 11 limit the movement of the lower and upper templates 5 and 4. An inlet 14 is located in the middle of the inner part of product groove 12, and a filling port 15 is fixedly located in the middle of the upper part of the mounting plate 2. Both inlet 14 and filling port 15 are used to fill the material.

[0027] See Figure 1 and Figure 2 The auxiliary rod 3 is provided in two sets, and the structure of each set of auxiliary rod 3 is the same. By setting the auxiliary rod 3, the upper template 4 can be moved up and down.

[0028] See Figure 1 and Figure 2 The positioning pins 6 and positioning sleeves 7 are each provided in four sets, and the positioning pins 6 and positioning sleeves 7 are matched and set. By setting the positioning pins 6 and positioning sleeves 7, the lower template 5 and the upper template 4 can be positioned.

[0029] See Figure 3 and Figure 4There are four notches 1 (8) and 2 (9), symmetrically located at the four corners of the upper template 4 and the lower template 5. The positioning pins 6 and positioning sleeves 7 can be installed by setting notches 1 (8) and 2 (9).

[0030] See Figure 1 and Figure 3 The dimensions of product slot 10 and product slot 2 are adapted to each other, and adhesive can be filled by setting product slot 10 and product slot 2.
