[0002] The Chinese name of PIR is "polyisocyanurate", also known as "polyisocyanurate", also known as "polyisocyanurate foam PIR" or "polyester PIR". PIR is a foaming material made by the reaction of isocyanate with polyether after catalyst. Its physical and fire resistance are better than general polyurethane. It is an ideal organic low-temperature insulation material with low thermal conductivity, light weight and strong adaptability. It is widely used in refineries, chemical plants, ethylene, fertilizers, cold storage and construction industry insulation.

[0014] To achieve the above purpose, another technical solution adopted by the present application is: a method for using a PIR high-pressure foaming device, comprising the following steps: S1: During processing, the cylinder is started to drive the upper mold upward, and the lower mold will rotate outward. When the lower mold rotates to an inclined position, the turntable drives the lower mold to move to the spray gun position as a whole.

Before moving, the upper and lower molds will first pass through the rotating plate. Before the upper and lower molds pass through the rotating plate, the cylinder will be started first. The cylinder will drive the upper mold away from the lower mold. When the cylinder drives the upper mold away from the lower mold, the top frame of the upper mold will rotate at the same time, and the second gear connected to the top frame will push the rack to move into the bottom groove. After the slide seat is pushed, it will drive the support rod to lift the bottom plate, and the lower mold will rotate and remain in an inclined state. At this time, the top head extends out, and after passing through the extension seat, it will push the extension seat, and the rotating plate will drive the suction cup to move into the lower mold. When the suction cup moves to the foamed material after molding, it will absorb the foamed material. The staff will then rotate the rotating plate to a horizontal position, and the molded foamed material can be removed.

[0015] Compared with the prior art, the beneficial effects of this application are: The PIR high-pressure foaming equipment and method, when using the foaming equipment for production, first control the upper mold and the lower mold to keep in a separated state, and then control the turntable to drive the lower mold as a whole, and when it moves to the spray gun position, the spray gun can inject the foaming material into the lower mold, and after the injection is completed, the cylinders on the upper mold and the lower mold are started again, and the cylinders can drive the upper mold to reset. During the resetting process, the lower mold will also reset through linkage, and the upper mold and the lower mold can be overlapped. After the overlap, the foaming material will be foamed and formed in the upper mold and the lower mold. After foaming and forming, the upper mold and the lower mold are moved to the rotating plate position and opened again, and the upper mold and the lower mold are separated again and formed. The foamed product can be exposed, and the screw on the side after the upper mold and the lower mold are separated will also be driven, and the ejector head will move to the extended seat position. After the ejector head pushes the extended seat, the extended seat will rotate in the pushing direction, and the rotating plate connected to the extended seat will move to the lower mold position. After a suction cup is provided on the rotating plate, the suction cup will follow the rotating plate to extend into the lower mold, so that the suction cup is adsorbed on the foamed product. After the suction cup is adsorbed, the cylinder is started again, and the cylinder drives the upper and lower molds to move slightly. At this time, the ejector head will be reset, so that the extended seat will not be pushed. When the staff pulls the rotating plate to a horizontal state, the foamed product can be removed.

When a support rod is installed on the slide seat, the support rod can push the bottom plate when it is opened, and the lower mold on the bottom plate can rotate and adjust with the bottom plate, and finally keep the inclined state. When the support rod is recovered, the lower mold and the bottom plate are reset. A rack is arranged on the slide seat, the rack meshes with the second gear, the second gear meshes with the first gear, and the first gear is connected to the first rotating rod on the top frame. When the top frame is driven by the cylinder, the top frame will move away from the lower mold together with the upper mold. At this time, the first gear will transmit the second gear, and the second gear will drive the rack to move into the bottom groove, so that the support rod is opened, so that the position of the lower mold on the bottom plate is adjusted. At this time, the upper and lower molds overlap, and the reverse operation can be performed. When the lower mold is tilted, it can not only facilitate the adsorption of the suction cup, but also realize that the foaming material is evenly spread in the mold during the reset process.

[0040] like Figure 1-Figure 7 As shown, a method for using a PIR high pressure foaming device comprises the following steps: S1: During processing, the cylinder 7 is started to drive the upper mold 10 upward, and the lower mold 4 will rotate outward. When the lower mold 4 rotates to an inclined position, the turntable 5 drives the lower mold 4 to move as a whole to the position of the spray gun 3. The spray gun 3 is moved to the position of the lower mold 4 through the control of the mechanical arm 2. The spray gun 3 can spray the foaming material into the lower mold 4. After the foaming material is injected, the cylinder 7 is started again. The cylinder 7 drives the upper mold 10 to reset. During the resetting process of the upper mold 10, the lower mold 4 will also reset. The upper mold 10 and the lower mold 4 can overlap, and the foaming material will be reacted and formed in the mold; S2: After the foaming material is formed, the turntable 5 will drive the upper and lower molds 4 to move toward the spray gun 3 position again as a whole. Before moving, the upper and lower molds 4 will first pass through the rotating plate 14. Before the upper and lower molds 4 pass through the rotating plate 14, the cylinder 7 will be started first. The cylinder 7 will drive the upper mold 10 away from the lower mold 4. When the cylinder 7 drives the upper mold 10 away from the lower mold 4, the top frame 126 of the upper mold 10 will rotate at the same time, and the second gear 125 connected to the top frame 126 will push the rack 132 to move into the bottom groove 136. After the slide seat 137 is pushed, it will drive the support rod 131 to lift the bottom plate 8, and the lower mold 4 will rotate and maintain an inclined state. At this time, the top head 182 extends out, and the top head 182 will push the extension seat 181 after passing through the extension seat 181. The rotating plate 14 will drive the suction cup 16 to move into the lower mold 4. When the suction cup 16 moves to the foamed material after molding, it will absorb the foamed material. The staff will then rotate the rotating plate 14 to a horizontal position, and the molded foamed material can be removed.

[0041] The working principle of the present invention is as follows: when the foaming equipment is used for production, the upper mold 10 and the lower mold 4 are first controlled to remain separated, and then the turntable 5 is controlled to drive the lower mold 4 as a whole. When the turntable 5 moves to the position of the spray gun 3, the spray gun 3 can inject the foaming material into the lower mold 4. After the injection is completed, the cylinder 7 on the upper mold 10 and the lower mold 4 is started again, and the cylinder 7 can drive the upper mold 10 to reset. During the resetting process, the lower mold 4 will also reset through linkage, and the upper mold 10 and the lower mold 4 can overlap. After the overlap, the foaming material will be foamed and formed in the upper mold 10 and the lower mold 4. After the foaming and forming, the upper mold 10 and the lower mold 4 are moved to the position of the rotating plate 14 and opened again. After the upper mold 10 and the lower mold 4 are separated again, the foamed product after molding can be exposed. 0 and the lower mold 4 are separated, the screw 183 on the side will also be driven, the top head 182 will move to the position of the extension seat 181, the top head 182 pushes the extension seat 181, and the extension seat 181 will rotate in the pushing direction, and the rotating plate 14 connected to the extension seat 181 will move to the position of the lower mold 4, and the suction cup 16 is provided on the rotating plate 14. After the suction cup 16 is extended into the lower mold 4 with the rotating plate 14, the suction cup 16 is adsorbed on the foamed product, and the cylinder 7 is started again after the suction cup 16 is adsorbed, and the cylinder 7 drives the upper and lower molds 4 to move slightly. At this time, the top head 182 will be reset, so that the extension seat 181 will not be pushed, and the staff can remove the foamed product when pulling the rotating plate 14 to a horizontal state. The whole process only needs to operate the rotating plate 14 to remove it, thereby reducing the labor intensity of the staff.

[0042] By opening a bottom groove 136 on the base 9, a cross bar 134 can be installed inside the bottom groove 136, and a slide 137 can be installed on the cross bar 134. The slide 137 can slide along the cross bar 134. When the support rod 131 is installed on the slide 137, the support rod 131 can push the bottom plate 8 when it is opened, and the lower mold 4 on the bottom plate 8 can rotate and adjust with the bottom plate 8, and finally keep the inclined state. When the support rod 131 is recovered, the lower mold 4 and the bottom plate 8 are reset, and a rack 132 is provided on the slide 137, and the rack 132 meshes with the second gear 125, and the second gear 125 meshes with the first gear 12 3. The first gear 123 is connected to the first rotating rod 122 on the top frame 126. When the top frame 126 is driven by the cylinder 7, the top frame 126 will move away from the lower mold 4 together with the upper mold 10. At this time, the first gear 123 will transmit the second gear 125, and the second gear 125 will drive the rack 132 to move into the bottom groove 136, so that the support rod 131 is opened, so that the position of the lower mold 4 on the bottom plate 8 is adjusted. At this time, when the upper and lower molds 4 overlap, the reverse operation can be performed. When the lower mold 4 is tilted, it can not only facilitate the adsorption of the suction cup 16, but also realize that the foaming material can be evenly spread in the mold during the resetting process.
