Technical Field
[0001] The utility model relates to the technical field of production equipment for composite material plates, in particular to a die insulation device for pultrusion molding. Background Art
[0002] Pultrusion dies play a vital role in the pultrusion process. Their functions include shaping, determining cross-sectional shapes, and controlling dimensional accuracy. These dies are usually composed of a mold shell and an inner core. The mold shell determines the shape of the product, and the inner core is used to control the shape of the internal cavity of the product. The working principle of pultrusion is to extrude the metal billet into the mold by applying pressure so that it takes the desired shape inside the mold. When the pultrusion process is used to manufacture the sheet, the mold used needs to be kept at a high temperature of about 200 degrees for a long time. In order to maintain this state, it is necessary to continuously provide a high amount of power consumption for the heating plate of the mold. The high-temperature mold is directly exposed to the outside, and the temperature around it is too high, and the working environment of the workers is relatively poor. The working principle of the heating plate is to heat the heating plate to a certain temperature first, then stop working, and wait until the temperature drops to a critical value before heating again. This intermittent and intermittent heating method wastes a lot of energy. It always needs to maintain the temperature of the heating plate and the mold, and work continuously, which greatly increases the production cost of the pultrusion mold. Utility Model Content

[0023] A longitudinal fixing structure 4 is installed on one side of the interior of the heat-insulating shell 1. The longitudinal fixing structure 4 includes a threaded shaft 401 rotatably installed on one side of the interior of the heat-insulating shell 1.
