Description

Technical Field

[0001] The invention relates to the technical field of thermal insulation strip processing dies, and in particular to a thermal insulation strip extrusion combined die and a thermal insulation strip processing method. Background Art

[0002] In the process of extrusion forming of thermal insulation strips, in order to obtain qualified thermal insulation strip profiles, extremely high requirements are placed on process parameters such as the temperature of the extrusion die and the pulling speed of the extrusion die. Therefore, cooling the corresponding parts of the extrusion die is an important issue that needs to be solved in the thermal insulation strip processing technology. In addition, the produced thermal insulation strips need to be cooled due to their high temperature. Currently, the cooling treatment of the thermal insulation strips is mostly carried out after molding by adding new cooling equipment, and cannot be carried out during the basic mold molding process. On the other hand, the current extrusion die cannot control its extrusion speed during the thermal insulation strip molding process, resulting in low production efficiency.

[0003] For example, a thermal insulation strip extrusion die disclosed in Chinese patent publication number CN211441091U can increase the moving speed of the thermal insulation strip in the molding cavity and improve production efficiency by setting a conveying roller; and can reduce the temperature of the thermal insulation strip by heat conduction during the molding process of the thermal insulation strip by setting a cooling channel, so that the produced thermal insulation strip does not need to undergo a cooling process; the water in the cooling channel can be replaced by setting a water inlet, a water outlet, and a connected water trough and a cooling pool; and the automatic replacement of cooling water in the cooling channel can be achieved by setting a first one-way valve, a second one-way valve and a pressure controller.

[0004] However, before the insulation strip is blow-molded and cooled, the material molecules of the insulation strip penetrate the surface of the mold under heating and pressure, which can easily lead to adhesion of the molded insulation strip and the molding cavity. In addition, due to the design of the conveying roller, it is difficult for the above-mentioned basic mold to ensure the sealing during the blow molding process, resulting in bubbles in the molded product.
