[0040] In order to improve the lamination effect, the present invention can produce three kinds of polyurethane insulation boards by using this set of molds 102, namely Figure 14The underlying insulation board A-1, the middle insulation board A-2, and the top insulation board A-3 shown. To clearly describe the working principle of the present invention, we take Figure 1 as the azimuth perspective for elaboration, as follows: S1. The output end of the first stepping motor 204 drives the first lead screw 202 to rotate, so that the three bottom covers 212 move to directly below the mold 102. The elongation of the output end of the second electric push rod 210 drives the three bottom covers 212 to move upward, realizing the occlusion of the three first notches 104 opened at the bottom of the mold 102. The output end of the second stepping motor 304 drives the second lead screw 302 to rotate, so that the three second arc-shaped molds 308 move to directly above the mold 102. The elongation of the output end of the fourth electric push rod 306 drives the three second arc-shaped molds 308 to move downward. The three second arc-shaped molds 308 are respectively inserted into the three second notches 105 opened at the top of the top plate 103. And sealing grooves and sealing ring structures are provided at the joints between the three bottom covers 212 and the bottom of the mold 102 and between the three second arc-shaped molds 308 and the top of the mold 102, realizing the sealing of the mold 102. Raw materials are injected into the mold 102 through the injection port 106, so that the underlying insulation board A-1 is formed. After that, the three second arc-shaped molds 308 are reset under the contraction of the output end of the fourth electric push rod 306. And the output end of the third stepping motor 404 drives the third lead screw 403 to rotate, so that the top plate 103 moves upward, no longer occluding the top opening of the mold 102. Then, the elongation of the output ends of the two third electric push rods 213 drives the ejector plate 214 to move upward, ejecting the formed underlying insulation board A-1, and transferring it to the top of the workbench 107 through the robotic arm 101; S2. The output end of the fourth stepping motor 504 drives the fourth lead screw 502 to rotate, so that the two first clamping plates 505 approach each other, clamping and fixing the underlying insulation board A-1 on the top of the workbench 107; S3. The output end of the first stepping motor 204 drives the first lead screw 202 to rotate, so that the three first arc-shaped molds 208 move to directly below the mold 102. The elongation of the output end of the first electric push rod 206 drives the three first arc-shaped molds 208 to move upward, occluding the three first notches 104 opened at the bottom of the mold 102. The top plate 103 covers the top opening of the mold 102. The three second arc-shaped molds 308 are still respectively inserted into the three second notches 105 opened at the top of the top plate 103. Raw materials are injected into the mold 102 through the injection port 106; S4. The output end of the drive motor 109 drives the drive gear 110 to rotate, and then the driven gear 108 rotates, so that the lifting frame 705 is located directly above the underlying insulation board A-1 and is parallel to the front edge line of the underlying insulation board A-1 (as Figure 11As shown, by the combined use of the output ends of the second servo motor 708 and the third servo motor 712, the glue spraying head 715 moves back and forth and left and right above the bottom thermal insulation board A-1. Under the action of the output end of the first servo motor 704, the glue spraying head 715 moves downward, and the glue spraying head 715 sprays glue onto the top of the bottom thermal insulation board A-1. After the middle thermal insulation board A-2 is formed in the mold 102, the three groups of first arc-shaped molds 208 and the three groups of first arc-shaped molds 208 are reset. The ejector plate 214 moves to directly below the mold 102. The elongation of the output ends of the two groups of third electric push rods 213 drives the ejector plate 214 to move upward, ejecting the formed middle thermal insulation board A-2, and transferring it to the top of the bottom thermal insulation board A-1 on the workbench 107 and fitting it through the robotic arm 101. The arc-shaped protrusions at the bottom of the middle thermal insulation board A-2 are located in the arc-shaped grooves at the top of the bottom thermal insulation board A-1. Then, it is pressed by the pressing plate 716, thereby realizing the composite molding of the middle thermal insulation board A-2 and the bottom thermal insulation board A-1; S5. Increase the number of middle thermal insulation boards A-2 according to the thickness of the polyurethane thermal insulation board to be produced, and repeat the above steps to continue spraying glue on the top of the middle thermal insulation board A-2 and laminating and molding the middle thermal insulation board A-2; S6. The output end of the first stepping motor 204 drives the first lead screw 202 to rotate, so that the three groups of first arc-shaped molds 208 move to directly below the mold 102. The elongation of the output ends of the first electric push rods 206 drives the three groups of first arc-shaped molds 208 to move upward to block the three groups of first notches 104 opened at the bottom of the mold 102. The output end of the second stepping motor 304 drives the second lead screw 302 to rotate, so that the three groups of top cover plates 312 move to directly above the mold 102. The elongation of the output ends of the fifth electric push rods 310 drives the three groups of top cover plates 312 to move downward to block the three groups of second notches 105. Raw materials are injected into the mold 102 through the injection port 106 to form the top thermal insulation board A-3, and it is transferred to the top of the middle thermal insulation board A-2 on the workbench 107 and fitted through the robotic arm 101. Repeated lamination is carried out, thereby realizing the automated production of polyurethane thermal insulation boards. During the lamination process, due to the cooperation of the arc-shaped protrusions and the arc-shaped grooves, the contact area is increased, the pasting effect is better, the production quality of the polyurethane thermal insulation board is improved, and no staff operation is required, meeting the needs of the staff; S7. It should be noted that during the lamination process, excess glue will flow out along the four edges of the polyurethane insulation board. The two groups of first clamping plates 505 clamp the two sides of the polyurethane insulation board. The output end of the driving motor 109 drives the driving gear 110 to rotate, and then the driven gear 108 rotates, causing the first vertical plate 601 to rotate to the other two sides of the polyurethane insulation board. The elongation of the output end of the sixth electric push rod 606 drives the connecting frame 607 to move towards the position close to the center of the driven gear 108. Then, the output end of the sixth stepping motor 604 drives the sixth lead screw 602 to rotate, causing the connecting frame 607 to move downward, realizing that the connecting frame 607 "bypasses" the second clamping plate 510. Then, the elongation of the output end of the seventh electric push rod 612 drives the first scraper 613 to contact the side wall of the polyurethane insulation board. Next, the output end of the seventh stepping motor 610 drives the seventh lead screw 608 to rotate, causing the first scraper 613 to reciprocate up and down to scrape the glue on the side wall of the polyurethane insulation board clean. Under the action of the output end of the fifth stepping motor 509, the two groups of second clamping plates 510 move closer to clamp and fix the polyurethane insulation board, while the two groups of first clamping plates 505 release the clamping. Then, repeat the above steps to clean the glue on the two sides clamped by the two groups of first clamping plates 505, thus realizing cleaning without dead angles. After cleaning these two sides, the output end of the eighth stepping motor 617 drives the eighth lead screw 615 to rotate, causing the second scraper 618 to move to the back of the connecting frame 607. Then, under the contraction action of the output end of the sixth electric push rod 606, the second scraper 618 is driven to contact and fit with the first clamping plate 505. Again, the output end of the seventh stepping motor 610 drives the seventh lead screw 608 to rotate, causing the first scraper 613 to reciprocate up and down to scrape the glue on the outer wall of the first clamping plate 505. It is convenient and fast, realizing automatic cleaning.
