Embodiment 1

[0031] The multi-color double-density one-time molding process of rubber products in this embodiment completes the addition of multi-color double-density rubber materials (manually added), hollowing, foaming and vulcanization processes in the same mold cavity, and the mold cavity includes The cavity formed by the upper half mold, the lower half mold, the mold core and the three. The mold core lays the foundation for the hollow of the mold cavity. After being hollow, it has the conditions for filling the high temperature and high pressure gas required for vulcanization and foaming expansion to reduce the density. The high pressure required for vulcanization is generated while foaming and expanding, and then the manual feeding, hollowing, foaming and vulcanizing devices are integrated, which avoids the heat loss and process circulation costs caused by the circulation of various processes in the prior art, and solves the problem of traditional rubber products. The multiple times o...

Embodiment 2

[0033] The multi-color and double-density one-time molding process of rubber products in this embodiment, the specific steps are:

[0034] Step 1. Multi-color and double-density feeding: Open the upper film and mold core, manually add the rubber material into the cavity of the lower film, close the core, then manually add the rubber material into the cavity of the upper film, close the upper film and pump Vacuum, then the mold cavity can be heated to 130-180°C. The purpose can be achieved by adding heaters to the outer walls of the upper half mold and the lower half mold to ensure the vulcanization requirements of rubber products. Stand for 5-50s to form, according to the specifications of rubber products According to the requirements of shape or shape; the rubber materials are high-density rubber materials of one or several colors and low-density rubber materials of one or several colors, wherein the low-density rubber materials are high-density rubber materials. Foaming agen...

Embodiment 3

[0042] The multi-color double-density one-time molding process of rubber products of the present embodiment produces 34 yards of children's shoes soles. The shapes of the upper half mold, the lower half mold and the mold core are consistent with the shapes of the children's shoes soles. The specific steps are:

[0043] Pre-order preparation steps, rubber plasticization: high-density rubber is plasticized by regenerated rubber particles of cross-linkable waste rubber in the plasticizing injection screw, and the plasticized fluid rubber is temporarily stored in the plasticizing chamber , the plasticizing temperature is 60°C, the purpose is to fluidize the rubber material, facilitate the subsequent injection, and keep it warm. It can be kept warm by a built-in heater in the ring wall of the plasticizing material cavity; the low-density rubber material is another kind of or multi-color mixed rubber composition, the rubber particles are plasticized in another plasticizing injection ...

Abstract

The invention discloses a rubber product multi-color dual-density one-time compression molding forming process, and belongs to the technical field of a rubber product technology. According to the rubber product multi-color dual-density one-time compression molding forming process, adding (manual adding), hollow operation, foaming and vulcanization procedures of multi-color dual-density rubber arefinished in the same mold cavity, the mold cavity comprises an upper half mold, a lower half mold, a mold core and a cavity formed by the upper half mold, the lower half mold and the mold core, the mold core is a hollow foundation of the mold cavity, after hollow operation, conditions of inflating high-temperature high-pressure gas needed by vulcanization and density reducing for foamed expansionare achieved, high pressure needed by vulcanization is generated while foamed expansion is achieved, a hollow, foaming and vulcanization device is integrated, and the problems that in the prior art, due to circulation of procedures, heat losses are caused, work procedure circulation cost is increased, due to repeated pressurizing and heating and secondary glue bonding of a traditional rubber product production process, energy and time are consumed, and cost is high are solved.

Description

technical field [0001] The invention belongs to the technical field of rubber products, and in particular relates to a multi-color and double-density disposable molding process for rubber products. Background technique [0002] Existing multi-color double-density rubber products, such as the multi-color double-density soles produced by Adidas and Nike (the bottom layer is high-density, wear-resistant, non-slip, and the upper layer is low-density, good elasticity, and light). Sheets with different densities are cut and formed and glued together manually or mechanically with special glue. The low-density sheets are usually vulcanized in the next process after foaming outside the mold. Its defect is that there are many processes, it is difficult to ensure stable quality due to glue adhesion, and the failure rate is high. Moreover, it is easy to pollute the environment, requires a lot of labor, and the cost is relatively high. [0003] Existing rubber multi-color double-density...
