Embodiment Construction

[0049]After extensive and in-depth research, the inventor of the present application accidentally designed an automatic resin transfer molding injection machine suitable for continuous fiber reinforced polybutylene terephthalate thermoplastic composites for the first time, including: A first tank to heat the monomer, a second tank to hold the catalyst, and a third tank. The monomer and the catalyst are transported to the third material tank through their respective metering devices to be mixed into the injection material; the injection material is injected into the mold through the discharge port and the pipeline at the bottom of the third material tank for molding, and the The volume of the third material tank is greater than the volume of the injection material that the mold can accommodate. The glue injection machine is capable of automatic metering and mixing, automatic glue injection, continuous process and high glue injection efficiency. On this basis, the present inven...

Abstract

The invention discloses a resin transfer molding forming glue injection machine of continuous fiber reinforced PBT (polybutylece terephthalate) composite materials. The resin transfer molding forming glue injection machine comprises a first material tank, a second material tank and a third material tank, wherein the first material tank is used for containing monomers and heating the monomers, and the second material tank is used for containing catalysts. The monomers and the catalysts are respectively conveyed to the third material tank through respective metering devices to be mixed into glue injection raw materials, the glue injection raw materials are filled into a mold through a material outlet arranged at the bottom end of the third material tank and a connecting pipeline for carrying out molding forming, and in addition, the size of the third material tank is greater than the size of the mold for containing the glue injection raw materials. The automatic glue injection machine provided by the invention has the advantages that the metering blending and the glue injection can be automatically carried out, the process is continuous, and the glue injection efficiency is high.

Description

technical field [0001] The present invention relates to a glue injection machine, in particular to a resin transfer molding glue injection machine, in particular to a special resin transfer molding glue injection for continuous fiber reinforced polybutylene terephthalate (PBT) thermoplastic composite materials machine. Background technique [0002] At present, fiber-reinforced resin composites are usually prepared by resin transfer molding (Resin Transfer Moulding, RTM) method or vacuum assisted resin transfer molding (VARTM) method. The so-called resin transfer molding refers to the process of injecting resin into a closed mold containing reinforcing materials, such as reinforcing fibers, infiltrating the reinforcing materials and curing them. [0003] Continuous fiber reinforced polybutylene terephthalate (PBT) thermoplastic composites have higher mechanical properties, and have higher impact resistance than thermosetting resin-based composites and can be recycled. Theref...
