Description

Technical Field

[0001] The utility model belongs to the technical field of foaming of flat box insulation modules, and in particular relates to a foaming tooling for a flat box insulation module in a deep cold storage and transportation system. Background Art

[0002] The cryogenic storage and transportation system is used in large-scale liquefied natural gas transportation and storage. Its core feature is the use of special film materials and low-temperature insulation technology. The flat box insulation module is a flat box insulation module body structure formed by polyurethane foam combined with plywood. It is used in the insulation system of some liquid natural gas and liquid nitrogen storage tanks. It is one of the important components of film-type cryogenic storage tanks. It can greatly reduce the construction workload and shorten the construction period. It has the advantages of improving the cold preservation performance of film storage tanks and reducing the evaporation rate.

[0003] The existing flat box insulation module foaming tooling is used only for polyurethane foaming molding. After the polyurethane foaming is molded, the mold is removed and plywood is glued to the two outer sides of the flat box insulation module, which increases the production process of the flat box insulation module. In addition, the subsequent plywood bonding effect is not good, which affects the production efficiency and production quality of the flat box insulation module. For this reason, we propose a flat box insulation module foaming tooling for deep cold storage and transportation system. Utility Model Content

[0010] Preferably, the sealing assembly comprises a fixing frame and a sealing plate;

[0011] There are two fixing frames, which are symmetrically arranged on the outside of the injection port. The fixing frame is an inverted L-shaped structure. The middle of the sealing plate is located on the injection port, and the two ends of the sealing plate are respectively located in the two fixing frames.

[0012] Preferably, the top plate is provided with symmetrically distributed lifting ears.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the foaming tooling in the utility model is in use, a release agent is first applied to the inner surfaces of the bottom plate and the second side plate to prevent the polyurethane from adhering to the second side plate after foaming, which is helpful for demoulding after foaming. The first side plate and the second side plate are then fixed by locking the locking assembly. The plywood is then placed on the inner side surface of the first side plate. The suction system then tightly adsorbs the plywood on the inner side surface of the first side plate through the adsorption port and the adsorption pores. The fiberglass skeleton is then placed one by one between the first side plate and the second side plate at equal intervals. The release agent is then applied to the inner side surface of the top plate. The top plate is then fixed by locking the locking assembly and the first side plate to form a foaming molding space between the bottom plate, the first side plate, the second side plate and the top plate. The sealing assembly is then opened, and polyurethane foam is injected into the foaming molding space through the injection port. When the polyurethane foam is injected, the sealing assembly is opened. The injection port is sealed by the sealing component. As the polyurethane foams, the air in the foaming molding space is gradually discharged from the exhaust hole, so that the polyurethane can fill the entire tooling. Then the water pipe continues to heat the polyurethane foam material in the foaming molding space through the water bath heating system, accelerating the foaming and molding speed, so that the plywood and the polyurethane foam material are directly molded into an integrated structure. The foaming molding of the flat box insulation module is completed, and then the locking component is opened to remove the first side panel, the second side panel and the top panel. The plywood can be directly molded into an integrated structure with the polyurethane foam material, and there is no need to bond the plywood to the two outer sides of the polyurethane foam molding again, saving the production process and time cost of the flat box insulation module, while improving the molding stability of the plywood and the polyurethane foam molding, and improving the product quality of the flat box insulation module;

[0015] 2. The second side plate and the top plate can be locked and fixed with the first side plate by means of the locking hook and the locking head, and the second side plate and the top plate can be quickly assembled and disassembled with the first side plate, thereby improving the production efficiency of the flat box insulation module;

[0016] 3. By rotating the sealing plate counterclockwise, the sealing plate can be released from the limit between the two fixing frames, and then removed from the injection port to facilitate injection. Then the middle part of the sealing plate is placed on the injection port, and then the sealing plate is rotated clockwise to limit the position between the two fixing frames. The injection port can be sealed to achieve pressurized foaming, which is convenient for injection and sealing of the injection port. At the same time, the structure is simple, easy to use, and reliable in sealing. BRIEF DESCRIPTION OF THE DRAWINGS
