Description

Technical Field

[0001] This application relates to the field of foam shoe production technology, and in particular to a foaming device for producing EVA foam shoe materials. Background Technology

[0002] EVA is the main material for athletic shoe soles, offering advantages such as lightweight and shock absorption. The EVA one-piece molding process typically uses paired upper and lower molds. After adding EVA, fillers, foaming agents, crosslinking agents, and other materials, the upper and lower molds are kept in close contact and pressed together before heating to form the molded product.

[0003] Currently, when using foaming equipment to process shoe soles, a layer of release agent needs to be manually sprayed onto the lower molding heating mold to facilitate demolding after foaming and prevent adhesion that could cause inconvenience or damage to the molded foamed shoe sole. However, manual spraying requires workers to spray multiple lower molding heating molds in sequence, and continuous operation can easily lead to worker fatigue and slow down subsequent spraying efficiency. Therefore, in order to solve the above-mentioned problems, a foaming device for EVA foamed shoe material production has been designed. Utility Model Content

[0004] To address this problem, this application provides a foaming apparatus for producing EVA foamed shoe materials.

[0005] The EVA foaming shoe material production foaming device provided in this application adopts the following technical solution: An EVA foam shoe material production foaming device includes a processing box, a cylinder installed at the upper end of the processing box, a mounting plate fixedly connected to the lower end of the cylinder, and several upper molding heating molds fixedly connected to the lower end of the mounting plate. A lower molding heating mold corresponding to the upper molding heating mold is installed at the upper end of the processing box. Slide grooves are opened on both sides of the upper part of the processing box, and a movable frame is installed in the slide groove. A support rod is rotatably connected in the movable frame. Several spray pipes for spraying release agent are installed at the upper end of the support rod. Each spray pipe is connected to a transport pipe on one side close to each other. The drive assembly is fixedly installed on the upper part of the processing box and is used to adjust the support rod and moving frame to achieve automatic spraying of release agent.

[0006] Preferably, the drive assembly includes an electric push rod fixedly installed in the upper part of the processing box, the output end of the electric push rod is fixedly connected to a fixed plate, and a push plate for pushing the moving frame is fixedly connected to one side of the fixed plate.

[0007] Preferably, the drive assembly further includes a rack fixedly mounted on the upper rear part of the fixed plate, the lower end of the rack being provided with a gear capable of meshing with it, and a support rod being fixedly connected through the middle of one side of the gear passing through the side wall of the movable frame.

[0008] Preferably, one side of the nozzle is also fixedly connected to a flexible hose.

[0009] Preferably, one end of the hose is fixedly connected to a storage box, and the storage box is fixedly installed on one side of the processing box.

[0010] Preferably, the lower end of the movable frame is fixedly connected to a slider, the lower end of the slider is slidably connected to a slide groove, the rear part of the slider is fixedly connected to an elastic sheet, and the rear part of the elastic sheet is fixedly connected to the inner wall of the slide groove.

[0011] In summary, this application includes the following beneficial technical effects: In this invention, the structure consisting of a movable frame, support rod, chute, spray pipe, and transport pipe can replace manual spraying of release agent, enabling automatic spraying of release agent before each foaming process to ensure smooth demolding after foaming. This reduces the labor intensity of workers, improves demolding efficiency during continuous foaming operations, and the push plate, gears, and racks can drive the support rod, spray pipe, and movable frame to move and adjust, facilitating uniform spraying during use and easy storage after use.

Detailed Implementation

[0014] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0015] This application discloses a foaming apparatus for producing EVA foamed shoe materials. (Refer to...) Figure 1-4An EVA foam shoe material production foaming device includes a processing box 1. A cylinder 2 is installed on the upper end of the processing box 1, and a mounting plate 3 is fixedly connected to the lower end of the cylinder 2. Several upper molding heating molds 4 are fixedly connected to the lower end of the mounting plate 3. A lower molding heating mold 5 corresponding to the upper molding heating mold 4 is installed on the upper end of the processing box 1. Sliding grooves are opened on both sides of the upper part of the processing box 1, and a movable frame 6 is installed in the sliding groove. The movable frame 6 can easily move the upper spray pipe 8, so as to move the spray pipe 8 backward and evenly spray the release agent onto the lower molding heating mold 5. A support rod 7 is rotatably connected in the movable frame 6. Several spray pipes 8 for spraying release agent are installed on the upper end of the support rod 7. Each spray pipe 8 is connected to a transport pipe 9 on one side close to each other. The support rod 7 can be used to move the spray pipe 8 to the upper end of the lower molding heating mold 5 for use, so as to facilitate the spraying of release agent. To facilitate the movement of the movable frame 6 and the rotation adjustment of the support rod 7, a drive assembly is also provided, which is fixedly installed on the upper part of the processing box 1. The drive assembly includes an electric push rod 12 fixedly installed in the upper part of the processing box 1. The output end of the electric push rod 12 is fixedly connected to a fixed plate 13. A push plate 14 for pushing the movable frame 6 is fixedly connected to one side of the fixed plate 13. The push plate 14 is used to push the movable frame 6 to move.

[0016] The drive assembly also includes a rack 15 fixedly installed on the upper rear part of the fixed plate 13. The lower end of the rack 15 is provided with a gear 71 that can mesh with it. The middle part of one side of the gear 71 passes through the side wall of the movable frame 6 and is fixedly connected to the support rod 7. The gear 71 and the rack 15 are used to drive the support rod 7 and the nozzle 8 to rotate.

[0017] By adopting the above technical solution, a hose 10 is also fixedly connected to one side of the nozzle 8. The hose 10 is malleable, and its configuration allows the support rod 7 to easily move and adjust the nozzle 8, thus avoiding affecting the movement and use of the nozzle 8. A storage box 11 is fixedly connected to one end of the hose 10, and the storage box 11 is fixedly installed on one side of the processing box 1.

[0018] By adopting the above technical solution, in order to facilitate the sliding of the movable frame 6, a slider 61 is fixedly connected to the lower end of the movable frame 6, the lower end of the slider 61 is slidably connected to the slide groove, and an elastic sheet 62 is fixedly connected to the rear of the slider 61. The rear of the elastic sheet 62 is fixedly connected to the inner wall of the slide groove. The elastic sheet 62 can drive the movable frame 6 driven by the push plate 14 to move and return to its original position, which facilitates the continuous use of the movable frame 6.

[0019] The implementation principle of the EVA foam shoe material production foaming device in this application embodiment is as follows: An electric push rod 12 can be activated, causing the electric push rod 12 to move the fixed plate 13. The fixed plate 13 then moves the push plate 14, which in turn moves the rack 15. The rack 15 first meshes with a gear 71 on one side, causing the gear 71 to rotate. The gear 71 then drives the support rod 7 on the moving frame 6 to rotate around the center of the gear 71, and consequently, the spray pipe 8 and the transport pipe 9 on it to rotate, ultimately rotating to the desired position. Figure 1 As shown, the nozzle 8 is located at the upper end of the lower molding heating mold 5. The pump is then started to transport the release agent from the storage tank 11 to the nozzle 8 for spraying onto the lower molding heating mold 5. Simultaneously, the electric push rod 12 continues to move the fixed plate 13, causing the push plate 14 to push the moving frame 6. The moving frame 6 moves backward, moving the support rod 7 and simultaneously compressing the elastic sheet 62 to contract. The support rod 7 then moves the nozzle 8, continuously and evenly spraying the release agent onto the lower molding heating mold 5. After spraying, the electric... Push rod 12 drives fixed plate 13, push plate 14 and rack 15 to return to their original positions. During the movement, elastic sheet 62 drives moving frame 6 to move and return to its original position. At this time, moving frame 6 is still connected to push plate 14 until it moves to the initial position. Then push plate 14 separates from moving frame 6. After that, rack 15 drives gear 71 to rotate in the opposite direction and drives support rod 7 to rotate and return to its original position for continued use. Then cylinder 2 is activated to drive the upper forming heating mold 4 at the lower end of mounting plate 3 to descend and connect with lower forming heating mold 5 for foaming processing.
