Problems solved by technology
At present, the glue injection / glue outlet is usually pre-manufactured on the mold body directly, and the thread is processed on the end of the hole. The plastic pipeline is completed with resin injection to obtain composite materials. When the mold is used again, since the injection / glue outlet hole and the double outer wire straight-through are completely blocked by the resin, machining is required to make the resin hole unobstructed, and the discarded double outer wire straight-through must be removed. Frequent replacement will cause damage to the connecting thread on the mold, resulting in frequent repairs of the mold, resulting in production stagnation and affecting production efficiency

Embodiment Construction
[0015] Such as Figure 1 ~ Figure 3 As shown, an RTM mold injection port structure, the injection port 3 communicates with the internal molding cavity of the mold body 1, the distinguishing feature of this application is that: the mold body 1 is provided with a rubber seat hole 4, and another one containing injection The injection seat 2 of the glue port 3 is sealed and connected with the mold body 1 through the seat hole 4. The injection seat 2 is a T-shaped structure composed of a flat end body 5 and a protruding guide column 6. The injection The center of the rubber seat 2 has a glue injection port 3 that runs through the end body 5 and the guide post 6 .
[0016] In a preferred embodiment, the guide column 6 of the injection seat 2 is a conical structure, matching with the tapered seat hole 4 on the mold body 1 .
[0017] In a preferred embodiment, the injection seat is made of rubber or resin.
[0018] In a preferred embodiment, an annular sealing groove 7 is provided o...

The invention discloses a RTM mould glue injection hole structure and a replacing method. A conical rubber base hole with a smooth inner wall is formed in a mould body; another glue injection base with the glue injection hole is in sealing connection with the mould body through the rubber base hole; the glue injection base is of a T-shaped structure, and consists of a planar end body and a convexguide column; the guide column is of a conical structure which is smooth with the outer wall matched with the rubber base hole; a glue injection hole which penetrates through the end body and the guide column is formed in the center of the glue injection base; a ring-shaped sealing slot is formed in the lower surface of the end body of the glue injection base; and a sealing ring is arranged in thesealing slot. In use, the guide column of the glue injection base is spliced into the rubber base hole of the mould body; the glue injection base is fixedly arranged on the mould body through a dowelpin and a fastening part; and when the glue injection base needs to replace, only the glue injection base needs to separate from the mould body for replacing a new glue injection base.
Description
technical field [0001] The patent of the present invention relates to the technical field of resin transfer molding (RTM for short) in the manufacturing technology of liquid molding composite materials, and specifically relates to a structure of an RTM mold injection outlet. Background technique [0002] With the continuous development of composite material manufacturing technology, the application of composite materials in aerospace and civil fields is also increasing. The application of liquid molding technology is also increasing. Resin transfer molding (RTM) technology, as the most promising technology in liquid molding technology, has gained more and more applications in the fields of military, civil aircraft and automobiles. As the key to RTM technology, RTM mold design directly affects the final product quality, pass rate, cost and mold life. [0003] RTM technology generally uses steel closed molds, and carbon fiber, glass fiber, etc. are used to lay prefabricated b...
