Taking this embodiment as an example, there are four second guide posts 22. The middle mold 4 has second guide holes corresponding to the second guide posts 22, and the second guide holes slide in conjunction with the second guide posts 22. The movable mold 3 has third guide holes corresponding to the second guide posts 22, and the third guide holes slide in conjunction with the second guide posts 22.

[0041] Combination Figure 5 and Figure 6 As shown, the mold clamping frame 1 is slidably connected with several first ejector rods 7. The first ejector rods 7 are located on the side of the fixed mold 2 away from the intermediate mold 4. Taking this embodiment as an example, there are two first ejector rods 7, which are spaced apart. The mold clamping frame 1 is connected to a drive assembly 8, which drives the two first ejector rods 7 to slide towards or away from the fixed mold 2. The mold clamping frame 1 is fixedly connected to a support plate 12, which is located on the side of the fixed mold 2 away from the intermediate mold 4. When the first ejector rods 7 are in the initial position, they are located between the fixed mold 2 and the support plate 12. Four third guide pillars 121 are connected between the support plate 12 and the fixed mold 2, and the two ends of the third guide pillars 121 are fixedly connected to the support plate 12 and the fixed mold 2, respectively. The drive assembly 8 includes a carrier plate 81 slidably connected to the third guide post 121 and two second drive components 82 fixedly connected to the side of the fixed mold 2 near the support plate 12.

[0042] Combination Figure 5 and Figure 7 As shown, two second push rods 112 are fixedly connected to the side of the vertical plate 11 near the movable mold 3, and the two second push rods 112 are distributed at intervals.

[0043] like Figure 5 As shown, a first feeding barrel 23 is fixedly connected to the upper end of the fixed mold 2, and a first discharge pipe is fixedly connected to the bottom of the first feeding barrel 23. The end of the first discharge pipe away from the first feeding barrel 23 is fixedly connected to the fixed mold 2. A support frame is fixedly connected to the upper surface of the movable mold 3, and a second feeding barrel 33 is fixedly connected to the support frame.

A second discharge pipe is fixedly connected to the bottom of the second feeding barrel 33, and the end of the second discharge pipe away from the second feeding barrel 33 is fixedly connected to the movable mold 3. The paths of the first discharge pipe and the second discharge pipe are the same.

[0044] The implementation principle of a dual-mold molding machine according to an embodiment of this application is as follows: As the movable mold 3 slides closer to the fixed mold 2, the active rack 51 slides along with it. Since both the active rack 51 and the passive rack 53 mesh with the gear 52, the active rack 51 drives the gear 52 to rotate during the sliding process. The gear 52, in turn, drives the intermediate mold 4 to move along with the active mold until the intermediate mold 4 and the movable mold 3 come into contact with each other. The first feeding tank 23 fills the fixed mold 2 with plastic foam granules, and the second feeding tank 33 fills the movable mold 3 with plastic foam granules until both the fixed mold 2 and the movable mold 3 are filled with plastic foam granules. After the product is formed, the first driving component 111 drives the movable mold 3 to slide away from the fixed mold 2, meaning the intermediate mold 4 also slides away from the fixed mold 2. The driving assembly 8 drives the first ejector rod 7 to slide closer to the fixed mold 2. The first ejector rod 7 passes through the fixed mold 2 and abuts against the formed product, causing the product to detach from the fixed mold 2. This facilitates the ejection of the product formed in the fixed mold 2, avoiding manual removal and improving the overall processing efficiency. When the movable mold 3 moves away from the fixed mold 2, the second ejector rod 112 abuts against the product inside the movable mold 3 and causes the product to detach from the movable mold 3. This also facilitates the ejection of the product formed in the movable mold 3, avoiding manual removal and improving the overall processing efficiency.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
