[0002] Fiberglass, also known as glass fiber reinforced plastic, commonly known as FRP (Fiber Reinforced Plastics), that is, fiber reinforced composite plastic. It is divided into glass fiber reinforced composite plastic (GFRP), carbon fiber reinforced composite plastic (CFRP), boron fiber reinforced composite plastic, etc. according to the different fibers used. When fiberglass materials are produced and processed, a pultrusion die is required for extrusion molding, and when the pultrusion die is used, it needs to be installed and fixed. Most of the current installation methods are to place the pultrusion die on a forming frame and then use heavy objects to apply pressure for fixation. This method has an unsatisfactory fixation effect on the pultrusion die. During the production process of fiberglass by the pultrusion die, the pultrusion die is prone to move, resulting in deformation of the pultruded fiberglass products, and there are certain defects in use. Therefore, a special fixture for a fiberglass pultrusion die is now proposed. Summary of the Utility Model
