Description
Technical field
The invention patent relates to resin transfer molding (abbreviation RTM) skills in liquid molding manufacture technology of composite material
A kind of art field, and in particular to RTM mold injecting glue sealant outlet structure.
Background technology
With the continuous development of manufacture technology of composite material, composite material dosage is in aerospace, the application of civil field
Also more and more.The application of Liquid molding techniques is also more and more, and resin transfer molding (abbreviation RTM) technology is as liquid
Most promising technology in forming technique obtains more and more applications in military and civilian's machine and automotive field.And
RTM mold is configured as the key in RTM technologies, directly affects the final quality of product, qualification rate, cost and mold longevity
Life.
RTM technologies generally use steel closed mould, and the pavings precast bodies such as carbon fiber, glass fibre are used in cavity,
It after molding, is infused resin into mold by gum-injecting port under the pressure of 3bar-6MPa, vacuum condition, after gum outlet plastic emitting
Injecting glue/gum outlet is closed, is cured by heating, composite material is obtained after cooling.Currently, injecting glue/gum outlet is often direct
Previously fabricated injecting glue/plastic hole on die ontology, and screw thread is processed in nose end, by the way that double outer silks are straight-through or other modes and ball
After valve connection, connection glue injection pipeline completes resin injection by injecting glue pipeline and obtains composite material, when mold reuses, by
It leads directly to and is blocked completely by resin in injecting glue/plastic hole and double outer silks, mechanical processing need to be used to keep resin hole unobstructed, and to remove useless
It is straight-through to abandon double outer silks, and frequently replacing can cause the connection screw thread on mold to damage, and mold is caused frequently to reprocess, and cause to produce
It stagnates, influences production efficiency.
Invention content
It is an object of the invention to overcome the deficiencies of the prior art and provide RTM mold glue injection structures, in injecting glue/gum outlet
When (injecting glue or plastic emitting only according to different objects for) damage, quickly realized the case where not influencing product line
Mold is safeguarded.
To achieve the above object, the application provides the following technical solutions：
A kind of RTM mold injecting glue mouth structure, gum-injecting port are connected to the forming cavity of die ontology, it is characterised in that：Mold sheet
It is set on body there are one rubber base hole, another there are one the injecting glue seats containing gum-injecting port to pass through the rubber base hole and die ontology sealed connection, institute
The injecting glue seat stated is a T-type structure, is made of the end body of plane and the guide post of protrusion, and the center of injecting glue seat has through end body
With the gum-injecting port of guide post.
The injecting glue seat guide post is a conical structure, is matched with the conical rubber bore on die ontology.Injecting glue
Seat is made of rubber or resin.The end body lower surface of injecting glue seat is additionally provided with annular seal groove, in order to ensure sealing effect,
There are two seal grooves, inner ring seal slot and outer ring seal slot, and sealing ring is equipped in seal groove.
In order to facilitate the installation of with replace injecting glue seat, be provided on the end body of injecting glue seat on die ontology corresponding mounting hole and
Location hole.
The beneficial effects of the invention are as follows：The present invention detaches the gum-injecting port on mold with die ontology, the note containing gum-injecting port
Rubber base is designed as standard component, is designed with double-layer seal slot, after installing sealing ring, after positioning pin and die ontology positioning, adopts
Injecting glue seat is connect with die ontology with connector, reaches the seal request of mold, the guide post of injecting glue seat, with die ontology portion
The rubber base hole divided is coordinated using tapered slope, and auxiliary ensures sealing effect.The present invention is ensureing that die ontology seals and intensity is wanted
Under the premise of asking, realize quick release replace function, reduce because use lesion ribbon come mold reprocess due to influence production stop
, improve production efficiency.
Technical scheme of the present invention is described in further detail below in conjunction with the accompanying drawings, but protection scope of the present invention is not limited to
It is as described below.
