Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a double-injection foamed thick-soled shoe material with inner ribs, so as to solve the problem that the foaming operation of EVA vinyl acetate copolymer is commonly used in one-time injection foaming compression molding. As a result, the stacking stability of multiple types of polymers of the same quality is insufficient, and it is easy to induce the phenomenon of product overflow and plugging die-casting due to the injection of excessive EVA during foaming, which will damage the product qualification and affect the efficiency of injection mold release. question

Embodiment 1

[0030] see Figure 1-Figure 7 , the present invention provides a double-injection-molded foamed thick-soled shoe material with inner ribs, the structure of which includes: a hydraulic mold frame 1, a double-injection frame 2, a rail bar frame 3, a lower hopper trough 4, a pressurized push Machine 5, chain belt body 6, interlayer shoe sole block 7, baking cabinet 8, the double injection molding frame 2 is nested on the left side of the pressurized pusher 5 and the axes are collinear, and the lower hopper tank 4 is inserted Embedded in the upper left corner of the booster pusher 5 and interpenetrated with each other, the booster pusher 5 is mechanically connected with the chain belt body 6, the booster pusher 5 is installed on the top of the rail bar groove frame 3 and is perpendicular to each other, The hydraulic mold frame 1 is nested on the left side of the double injection molding frame 2 and communicates with each other. The sandwich shoe sole block 7 is installed inside th...

Embodiment 2

[0035] see Figure 1-Figure 7 , the present invention provides a double-injection-molded foamed thick-soled shoe material with inner ribs, the other aspects are the same as in Example 1, the difference is that:

[0036] see Figure 4 , the hydraulic mold frame 1 is composed of an upper parting surface block 11, a hydraulic piston rod 12, a shoe mold pressure groove 13, a base plate 14, and a lower parting surface block 15, and the upper parting surface block 11 is nested in On the top of the hydraulic piston rod 12 and perpendicular to each other, the hydraulic piston rod 12 is inserted on the top of the shoe mold pressure groove 13, and the shoe mold pressure groove 13 is installed on the top of the base plate 14, the base The seat plate 14 is closely attached to the top surface of the lower parting surface block 15 and is on the same level, and the shoe mold pressure groove 13 is matched with the mold groove on the base plate 14 to accommodate the injection molding liquid t...

Abstract

The invention discloses a double-injection-molding feeding foaming thick-sole shoe material with inner ribs, which structurally comprises a hydraulic mold frame, a double-injection-molding machine frame, a track strip groove frame, a discharging hopper groove drum, a pressurizing pusher, a chain belt body, an interlayer sole block and a baking machine box. After alternate injection molding of the double injection molding cylinder grooves, the interlayer injection core pipe is used for processing the middle layer to form a reinforcing rib injection molding operation effect, so that the saturation degree of a shoe mold pressing groove foaming pressing mold is effectively achieved, the product size is matched, and the realizability and stability of an EVA middle as an interlayer are also improved; and the EVA foaming quality protection operation effect of the shoe sole in the composite rigidity adaptive wear-resisting tension and distortion of the reinforcing rib interlayer for preventing the shoe sole from being broken subsequently is improved.

Description

technical field [0001] The invention relates to a double-injection-molded foamed thick-soled shoe material with inner ribs, which belongs to the field of chemical processing. Background technique [0002] Injection molding molded shoe body embossing commonly used slippers and rubber soles to adapt to the durability of sports shoes and running shoes to improve the upper tension, and then use EVA vinyl acetate copolymer to form intermediate material saturation filling and shoe body processing operation For the general promotion and operation of foaming processing, the disadvantages to be optimized in the current technology are as follows: [0003] The foaming operation of EVA vinyl acetate copolymer is often used for the operation effect of one-time injection foaming compression molding, which is insufficient for the stacking stability of multiple types of polymers of the same quality, and it is easy to induce product overflow due to excessive EVA injection during foaming The...
