Embodiment Construction

[0031] In order to further explain the technical solution of the present invention, the present invention will be described in detail below through specific examples.

[0032] Such as figure 1 As shown, the present invention relates to a production equipment for air-free shoe materials, including a frame 1, an injection mechanism 2, a molding die 3, a die opening mechanism 4, and a vacuuming mechanism 5. In the present invention, the air-free The shoe material can be two-color or three-color shoe material.

[0033] The injection mechanism 2 injects shoe material raw materials into the forming mold 3. The forming mold 3 has a column 31, an upper heating plate 32, an upper mold 33, a lower heating plate 34 and a lower mold 35. The upper heating plate 32 is located at Above the upper mold 33 , the lower heating plate 34 is located below the lower mold 35 .

[0034] The die opening mechanism 4 has a mold opening and closing cylinder 41, a crank assembly 42 and a booster cylinder...

Abstract

The invention discloses a production device and process for bubble-free shoe materials. The production device for the bubble-free shoe materials comprises a rack, a material injection mechanism, a forming mold, a mold opening and drawing mechanism and a vacuumizing mechanism. The vacuumizing mechanism is provided with an upper vacuum cover, a lower vacuum cover, an ascending oil cylinder and a vacuum generator. By means of the arranged independent vacuumizing mechanism, during processing of semi-finished shoe materials through an upper mold body and a lower mold body while a color division plate is drawn out, the upper mold body, the lower mold body and the semi-finished shoe materials on the upper mold body and the lower mold body are totally put in an inner cavity formed by the upper vacuum cover and the lower vacuum cover and are then totally vacuumized, all bubbles concealed in the semi-finished shoe materials are eliminated, then pressurizing is performed through a pressurizing cylinder, heating is performed through an upper heating plate and a lower heating plate, and then the finished shoe materials are formed. By means of the production device and process for the bubble-free shoe materials, the high-quality bubble-free shoe materials can be formed, and the market competitiveness of the production device is greatly improved.

Description

technical field [0001] The invention relates to the field of shoe material processing equipment, in particular to a production equipment and a production process of a bubble-free shoe material. Background technique [0002] The foam molding machine for shoe materials is well known. The applicant once applied for and obtained the Chinese invention patent ZL201510074178.5, which discloses a three-color EVA injection foam molding equipment, but the current EVA injection foam molding equipment Among them, the shoe material formed by it still has some bubbles hidden inside, which ultimately affects the quality of the shoe material, and there is still room for improvement. In view of this, the inventor has studied deeply according to years of work experience, and then has this case to produce. Contents of the invention [0003] The main purpose of the present invention is to provide a kind of production equipment of bubble-free shoe material, and described bubble-free shoe mate...
