Detailed implementation manner

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] Please refer to Figure 1-6 , the present invention provides a technical solution: a forming die for producing a foam box capable of rapid cooling, including a fixing frame 1, a lower forming die 2, a positioning convex block 3, a fixed connection bolt 4, a fixed connection plate 5, a support plate 6, an electric telescopic rod 7, a mounting plate 8, an upper forming die 9, an adding groove 10, a limiting rod 11, a heating box 12, a heating device 13, a cooling component 14, a cooling inlet pipe 15, a cooling channel 16 and a cooling outlet pipe 17.

[0030] When using the forming die for producing a foam box capable of rapid cooling, as Figure 1 , Figure 2 and Figure 3 shown, first place the lower forming die 2 in the middle of the fixing frame 1, and positioning convex blocks 3 are fixedly connected to both the left and right ends of the lower forming die 2. At the same time, the positioning convex blocks 3 are aligned with the connection holes on the fixed connection plate 5. Then, by rotating the fixed connection bolts 4 threadedly connected to the left and right sides of the lower end of the fixing frame 1, the fixed connection bolts 4 rotate with the fixed connection plate 5, and the fixed connection bolts 4 drive the fixed connection plate 5 to expand and contract on the fixing frame 1, so that the positioning convex blocks 3 are respectively inserted into the front and rear ends of the fixed connection plate 5, and the fixed connection plate 5 is in a fitting arrangement with the lower forming die 2, thereby facilitating the extrusion and fixation of the lower forming die 2. At the same time, fix the upper forming die 9 to the lower end of the mounting plate 8 by bolts, and at the same time pass the limiting rod 11 through the card slot on the side of the fixing frame 1, and rotate the limiting rod 11 so that the limiting rod 11 is respectively threadedly connected to the left and right sides of the upper end of the upper forming die 9, and the convex blocks on the outer side of the limiting rod 11 are in a fitting arrangement with the outer side of the fixing frame 1, which is convenient for disassembling, installing, positioning and replacing the die;

[0031] After installation, start the electric telescopic rod 7 installed in the middle of the support plate 6. The output end of the electric telescopic rod 7 is fixedly connected with a mounting plate 8. The electric telescopic rod 7 drives the upper forming die 9 to move downward through the mounting plate 8, so that the upper forming die 9 is inserted into the lower forming die 2. During the up and down movement of the upper forming die 9, the limiting rod 11 is driven to slide between the fixed frame 1. By sliding between the limiting rod 11 and the fixed frame 1, the stability of the upper forming die 9 during the lifting movement is improved, preventing the upper forming die 9 from shifting, as Figure 1 and Figure 4 shown, an adding groove 10 is formed on the right front side of the upper forming die 9. The raw materials for producing the foam box are added into the die through the adding groove 10. Combining Figure 5 and Figure 6 shown, start the heating device 13 installed inside the heating box 12. The heating device 13 heats the lower forming die 2, so that the raw materials at the inner edge of the lower forming die 2 are further heated. In addition, during the cooling and forming process, through the setting of the cooling component 14, the cooling component 14 includes a cooling water inlet pipe 15 installed at the front end of the lower forming die 2, a cooling channel 16 formed in the bottom of the lower forming die 2, and a cooling water outlet pipe 17 installed at the rear end of the lower forming die 2;

[0032] Connect the cooling water inlet pipe 15 and the cooling water outlet pipe 17 to the external cooling water pipeline respectively. The cooling water is introduced into the cooling channel 16 through the cooling water inlet pipe 15 and then discharged through the cooling water outlet pipe 17 to achieve the effect of circulating cooling, which is convenient for cooling and forming the foam box. When the forming is completed, the upper forming die 9 is withdrawn from the fixed frame 1, and then the formed foam box can be taken out.

[0033] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
