Problems solved by technology

[0002] The traditional shoe making process is usually cumbersome. It needs to make the upper, sole, and footbed in sequence, and then combine them all.
The matching process of the shoe upper, sole, and footbed needs to be manually adjusted, and the glue is pasted. On the one hand, there are many places that need to be done manually, the quality is difficult to stabilize, and the rate of defective products is high. On the other hand, the amount of glue used is large, and it is not environmentally friendly.

Embodiment 1

[0045] The present embodiment provides a kind of preparation method of shoe shell, comprises the following steps:

[0046] (1) Prepare the rubber for shoe shells, and take the rubber for shoe shells of the required amount for shoemaking;

[0047] (2) Cut the shoe shell rubber obtained in step (1) into a strip or square size, so that the rubber can be properly arranged in the three-open shoe mold in the subsequent operation;

[0048] (3) if figure 2 and image 3 Shown is provided with three mold-opening shoe molds, which includes a machine platform 1 and a molding die 2 arranged on the machine platform 1, such as figure 2As shown, the forming mold 2 includes a bottom mold 21 movably arranged on the machine platform 1, and a mold main body 22 slidably arranged on the machine platform 1 and positioned at the side of the bottom mold 21, wherein the mold main body 22 includes A mold lower template 221, a mold upper cover plate 222 covered on the mold lower template 221, and a ...

Embodiment 2

[0071] The difference between this embodiment and embodiment 1 is:

[0072] The following formula is used for preparing shoe shell rubber in the step (1): 4 parts of SBR-1502 butadiene rubber, 8 parts of BR-9000 butadiene rubber, 18 parts of 3L natural rubber, 16 parts of white carbon black, dioxalic acid 2 parts of octyl esters, 0.8 parts of diethylene glycol, 0.5 parts of anti-wear agent SI-69, 1 part of zinc oxide, 0.2 parts of ST-stearic acid, 0.15 parts of SP-antiaging agent, 2 parts of PEG-40000, 0.1 parts of dibutyl hydroxytoluene parts, leveling agent AG-2020.5 parts, anti-cracking agent 0.2 parts, EPDM3168 parts.

[0073] The remaining parts are the same as those in Embodiment 1, and will not be repeated here.

Embodiment 3

[0075] The difference between this embodiment and embodiment 1 is:

[0076] In the step (1), the rubber for shoe shells is prepared using the following formula: 8 parts of SBR-1502 butadiene rubber, 12 parts of BR-9000 butadiene rubber, 14 parts of 3L natural rubber, 12 parts of white carbon black, dioxalic acid 6 parts of octyl esters, 0.3 parts of diethylene glycol, 0.2 parts of anti-wear agent SI-69, 3 parts of zinc oxide, 0.6 parts of ST-stearic acid, 0.10 parts of SP-antiaging agent, 0.5 parts of PEG-40000, 0.3 parts of dibutyl hydroxytoluene parts, leveling agent AG-202 1.5 parts, anti-cracking agent 0.1 parts, EPDM3163 parts.

[0077] The remaining parts are the same as those in Embodiment 1, and will not be repeated here.

Abstract

The invention discloses a manufacturing method of a shoe shell and a three-piece pattern shoe making mold. The three-piece pattern shoe making mold comprises a machine table and a forming mold, wherein the forming mold is arranged on the machine table and comprises a bottom mold and a mold main body; the bottom mold is movably arranged on the machine table; the mold main body is slidably arrangedon the machine table and is positioned on a side of the bottom mold; the mold main body comprises a mold lower plate, a mold upper cover plate and a mold core; the mold upper cover plate covers the mold lower plate; the mold core is embedded in the mold lower plate and the mold upper cover plate; a lower groove which allows the lower part of the mold core to be embedded is formed in the upper surface of the mold lower plate; an upper groove which allows the upper part of the mold core to be embedded is formed in the lower surface of the mold upper cover plate; and a cavity which is matched with a side of the mold core is formed in a side of the bottom mold. The technology of a whole process is greatly simplified, and the working efficiency is improved. By the three-piece pattern shoe making mold, the shoe shell is manufactured, and is obtained by an integrally forming process. Compared with the traditional shoe making process, the manufacturing method of the shoe shell has the advantage that the shoe shell is firm and durable.

Description

technical field [0001] The invention relates to a shoe preparation method and a mold, in particular to a shoe shell preparation method and a mold. Background technique [0002] The traditional shoe making process is usually cumbersome. It needs to make the upper, sole, and footbed in sequence, and then combine them all. The matching process of the shoe upper, sole, and footbed needs to be manually adjusted, and the glue is pasted. On the one hand, there are many places that need to be done manually, the quality is difficult to stabilize, and the rate of defective products is high. On the other hand, the amount of glue used is large, and it is not environmentally friendly. . If there is a preparation method that can integrally form the sole, the footbed, and part of the upper, the stability of product quality can be improved, and the amount of glue can be reduced at the same time. Contents of the invention [0003] In view of the above disadvantages, the object of the pre...
