[0027] Figure 6 Schematic diagram of the structure of the front drive mechanism and the rear drive mechanism according to an embodiment of the present invention. Figure 6 As shown, the structures of the front driving mechanism and the rear driving mechanism according to the embodiment of the present invention will be described in detail.

[0028] In order to prevent the mold from slipping, the front driving mechanism 41 and the rear driving mechanism 42 both include a second driving mechanism 412 and a driving slide 413 respectively arranged on both sides of the driving frame 411. The movable end of the second driving mechanism 412 is provided with a clamping frame 414, and a driving slider 415 is slidingly provided on the driving slide 413. The end of the clamping frame 414 away from the second driving mechanism 412 is slidably connected to the driving slide 413 through the driving slider 415. The second driving mechanism 412 drives the clamping frame 414 to move, and at the same time, the driving slider 415 moves along the driving slide 413. The clamping frame 414 is driven to move, and the mechanical transmission coordination relationship between the four is used to realize the pushing and removing function of the clamping frame 414. A first clamper 416 for clamping the mold is provided on the inner side of the clamping frame 414, wherein the front driving mechanism 41 is provided on the outer side of the rear driving mechanism 42 relative to the driving frame 411. During the secondary foaming molding, the lifting frame 43 drives the front driving mechanism 41 and the rear driving mechanism 42 to cooperate to push the mold into the heating molding device 2 and the cooling molding device 3 of the heating layer and the cooling layer, and clamps the mold through the first clamper 416; When the upper and lower layers are exchanged and coordinated, the lifting frame 43 first rises to the height of the heating layer. At this time, the clamping frame 414 on the front drive mechanism 41 carries a mold to be foamed for the second time. Then the rear drive mechanism 42 takes out the mold of the heating layer first, and then the front drive mechanism 41 pushes the mold to be foamed for the second time to the heating layer. After completion, the lifting frame 43 descends to the height of the cooling layer. The front drive mechanism 41 first takes out the mold for cooling and shaping, and then the rear drive mechanism 42 pushes the mold after the second foaming to the cooling layer for cooling and shaping. At this time, a new mold to be foamed for the second time is assembled on the front drive mechanism 41, so as to continuously exchange and coordinate up and down to ensure that there are three molds exchanged in turn at each station when the equipment is working, thereby improving work efficiency and reducing labor costs.

[0029] In order to improve the clamping stability, the first clamper 416 is a pneumatic clamper. The pneumatic clamping method can accurately control the clamping force to ensure that the mold is not damaged, while maintaining stable clamping and improving product quality and efficiency.

[0030] In order to improve the stability when pushing and removing the mold, the first driving mechanism 431 and the second driving mechanism 412 are pneumatic pistons.

[0031] Example 2 For the sake of simplicity in description, the parts that are the same as other embodiments will not be repeated here. The main description is of the structure that is different from other embodiments of the present invention. The difference between Example 2 and Example 1 lies in the different types of the first clamper, the first drive mechanism and the second drive mechanism.

[0032] In order to improve the clamping accuracy and safety, the first clamper 416 is a hydraulic clamper or an electric clamper, and adopts a hydraulic or electric clamping method to provide a stronger clamping force, thereby improving the processing accuracy and safety.

[0033] In order to ensure the stability of the mold removal operation under high working conditions, the first driving mechanism 431 and the second driving mechanism 412 are one of hydraulic pistons or electric pistons. The use of hydraulic pistons can provide huge thrust, which is suitable for industrial applications requiring high loads. The use of electric pistons can accurately control the position and accuracy, and has higher energy conversion efficiency, lower long-term operating costs, and meets environmental protection requirements.
