Embodiment 1

[0032] exist figure 1 Among them, the plastic warm rain boots are composed of a boot blank 1, a boot tube piece 2, a left piece under the ankle bone 3, a sole piece 4, and a right piece under the ankle bone. The geometric shape of the right sub-ankle bone piece and the left sub-ankle bone piece 3 is exactly the same. The upper end of the left piece 3 under the ankle bone is sewn together, and the right piece under the ankle bone is sewn together with the lower end of the left piece 3 under the ankle bone and the bottom of the foot piece 4 to make a thermal inner cover, the thermal inner cover and the boot blank 1 Paste the link.

[0033] The preparation process steps of the above-mentioned plastic warm rain boots are as follows:

[0034] 1. Making boot blanks 1

[0035] Make boot base 1 with plastics by conventional scale injection molding process step.

[0036] 2. Make a warm inner jacket

[0037] According to the model of rain boots, the artificial imitation fur is cut ...

Embodiment 2

[0053] In this embodiment, air is injected into the boot-shaped inflatable inner mold, and the air pressure is 0.00606 MPa. In the baking and pasting step, the boot with a thermal inner sleeve and a boot-shaped inflatable inner mold is placed inside the thermal inner sleeve. Blank 1 was put into an oven and baked at 60°C for 20 minutes. Other processing steps are identical with embodiment 1.

Embodiment 3

[0055] In this embodiment, air is injected into the boot-shaped inflatable inner mold, and the air pressure is 0.01515 MPa. In the baking and pasting step, a boot with a thermal inner sleeve and a boot-shaped inflatable inner mold is placed inside the thermal inner sleeve. Blank 1 was put into an oven and baked at 100°C for 12 minutes. Other processing steps are identical with embodiment 1.

Description

technical field [0001] The invention belongs to the technical field of shoes characterized by shape or use, and in particular relates to a preparation method of plastic or rubber-plastic thermal rain boots. Background technique [0002] In rivers, oil fields, and places in direct contact with acid, alkali and salt chemicals, in order to protect the health of operators, operators usually wear high rain boots. The rain boots dissipate heat quickly, and the temperature in the tall rain boots is low, and the feet of the operator are often frostbitten. In the cold season in the northern region, the operator usually needs to wear warm rain boots. [0003] There are two types of wellies currently on the market. One is a long-tube plastic molded injection-molded rain boot lined with a long tube of stockings pasted inside the long-tube plastic molded injection-molded rain boots. The preparation method is as follows: before injection molding, put the stockings on the inner mold, spr...
