Abstract

The invention provides high-temperature RTM (resin transfer molding) integrated molding equipment. The equipment comprises a resin tank, a high-temperature resin distributing pipeline and a curing tank, wherein the resin tank is arranged at the top of the curing tank in an integrated manner, the high-temperature resin distributing pipeline is arranged at the top part in the curing tank to meet the requirements of heat preservation property of the high-temperature resin distributing pipeline and the flowing property of the rein injection runners, the top part of the curing tank is provided with an opening at a glue outlet of the resin tank, three or more product molds can be placed in the curing tank, a mold vacuum pipeline is arranged outside the curing tank, the glue outlet of the resin tank is connected with the high-temperature resin distributing pipeline by a discharging valve, the high-temperature resin distributing pipeline is provided with three or more outlets, each outlet is connected with one mold through a resin distributing valve and a resin flowing pipeline, and each mold is connected with the mold vacuum pipeline by a liquid storage tank. According to the invention, high-temperature resin can be ensured to be fully poured and fed, the molding operation is convenient and the production efficiency is improved.

Description

technical field [0001] The invention relates to high-temperature RTM integrated molding equipment, in particular to an integrated molding equipment that integrates high-temperature RTM resin perfusion and high-temperature curing, can ensure the temperature of resin perfusion pipelines and realize high-efficiency production. Background technique [0002] Resin transfer molding, also known as RTM, is a molding technology of composite materials. It is a process method of injecting resin into a closed mold to infiltrate reinforcement materials and solidify composite materials. This process has high raw material utilization rate and low production cost. Low, the parts can be locally enhanced, the finish is good, the dimensional accuracy is high, and the process is simple. [0003] Traditional room temperature RTM molding equipment is suitable for infusing resin at 40-60°C, but not suitable for high temperature (higher than 150°C) infusion resin. The traditional high-temperature ...
