This also helps to reduce the probability of glue leakage accidents and material waste; and thus helps to improve the quality of molding and processing.

[0027] Specifically, in some implementations, such as Figure 1 and 2 As shown, the first elastic compression component 500 includes a first connecting block 510, a first compression spring 520, and a second connecting block 530 connected in sequence; the first connecting block 510 is connected to the bottom of the molding main plate 210 by welding or screws; the second connecting block 530 is connected to the top of the supporting base plate 220 by welding or screws. Wherein, as Figure 2 As shown, the top of the support base plate 220 is provided with a storage groove; the second connecting block 530 is disposed at the bottom of the storage groove; and most of the structure of the first compression spring 520 is disposed inside the storage groove when it is compressed, so as to promote the sealing performance of the mutual compression process.

[0028] Specifically, in some implementations, such as Figure 1 and 2 As shown, the supporting base plate 220 has a mounting groove 221 on one side surface facing the molded main plate 210; the bottom of the molded main plate 210 is movably disposed inside the mounting groove 221.

[0029] Specifically, in some implementations, such as Figure 1 and 2 As shown, the second elastic extrusion component 600 includes a third connecting block 610, a second extrusion spring 620, and a fourth connecting block 630 connected in sequence; the third connecting block 610 is connected to the bottom of the molding main plate 210 by welding or screws; the fourth connecting block 630 is connected to the inner bottom of the mounting groove 221 (i.e., located at the top of the support base plate 220) by welding or screws. This structure, through the cooperation of the second extrusion spring 620 and the first extrusion spring 520, can achieve a sealing closure between the molding main plate and the upper mold body by extruding and pushing from the circumferential direction, as well as a sealing closure between the molding main plate and the upper mold body by extruding and pushing from the bottom; thereby improving the tight sealing performance between the upper mold body and the lower mold body, and also helping to reduce the probability of glue leakage accidents and material waste; thus, it can help improve the quality of molding processing.

The other side of the first delivery pipe 420 passes through the support base plate 220 and extends to the mounting groove 221. One side of the input hose 430 is connected to the other side of the first delivery pipe 420. The other side of the input hose 430 is connected to the input... One end of the mounting pipe 440 is connected to the bottom of the molding main plate 210 and communicates with the cooling groove 215; one end of the output mounting section 450 is connected to the bottom of the molding main plate 210 and communicates with the cooling groove 215; the other end of the output mounting section 450 is connected to one end of the output hose 460; the other end of the output hose 460 is connected to one end of the second conveying pipe 470; the other end of the second conveying pipe 470 passes through the support base plate 220. This structure uses the blowing air of the air blower 410 to achieve air cooling, so as to avoid the cooling rate of the lower mold body 200 being gradual rather than abrupt; and the mobility of the input hose 430 and the output hose 460 ensures the stability of the upper and lower extrusion.
