Pipe joint for vacuum pouring technology

Abstract

The invention relates to a pipe joint for a vacuum pouring technology, which comprises a plug piece and a plastic injection block, wherein the plug piece is provided with a plastic injection joint end and a plastic guide joint end which are communicated, a pipe connection part is arranged outside the plastic injection joint end and is capable of sealing and communicating with a plastic injection pipe, and a buckling part is arranged outside the plastic guide joint end; and the plastic injection block is provided with a cavity of which a bottom part is communicated with a plastic guide pipe, acontaining hole for the inserting of the plastic guide joint end of the plug piece is arranged on the upper part of the cavity, a stopping part is arranged at the inner end of the containing hole; and the buckling part can be locked in the stopping part. By means of the structure, the traditional direct connection mode of pipes is mainly changed into the insertion communication mode of two plastic pieces, and in this way, the problem that the plastic injection pipe falls off from the plastic guide pipe is solved; and a sealing plastic strip is matched with the pipe joint, so that the integralprocess of the vacuum pouring is in the sealed state.

Description

technical field [0001] The invention relates to the production process of fan blades, especially a pipe joint in the vacuum infusion process that can be conveniently connected in the glue injection process and can be effectively sealed and prevented from falling out. Background technique [0002] The vacuum infusion process is a process technology that uses vacuum pressure to make shapes. The concept is to lay fiber reinforced materials and foam materials directly on the mold, then close the positive and negative molds (female and male molds) or wrap them with vacuum bags, seal the mold, and then use a vacuum pump to evacuate to a negative pressure state, and finally the resin Through the entire system of the injection pipe and then through the pipe, soak the component layup. Specifically, the fiber reinforced material is directly placed on the mold, and a layer of peeling layer is laid on the fiber reinforced material. The peeling layer is usually a thin layer of fiber fab...

Problems solved by technology

[0003] At present, the commonly used process molding method for large-scale wind power generation blades is the vacuum infusion method, which uses the glue injection tube directly into the diversion tube for vacuum infusion of resin. , from the beginning of vacuum infusion to the end of the initial curing of the product, it is necessary to ensure that the entire product is in a vacuum state. If there is any air leakage during this process, it will seriously affect the product quality (causing product defects or even product scrapping).
