Abstract
The utility model discloses a mould rubber outlet rapid connector applicable to a resin transfer molding process. The mould rubber outlet rapid connector comprises a connector body (1), a rubber sealing ring (2), a locking piece (4) and a nut (6), wherein the connector body (1) is in a thread double-outer-thread structure; the locking piece (4) is arranged inside the connector body (1), and is arranged outside the rubber sealing ring (2) in a sleeving manner; the connector body (1) is in threaded connection with the nut (6); the locking piece (4) comprises a cylinder and retracting strips (5); the cylinder is fixedly connected with the retracting strips (5); a lug boss (7) is arranged at one end of the nut (6), and is internally provided with a containing cavity; the shape of the containing cavity is the same as that of the lug boss (7); a through hole (8) is formed in the bottom of the lug boss (7). The mould rubber outlet rapid connector can be rapidly connected with a transparent rubber pipe and can be repeatedly utilized so that the cost is reduced; the rubber sealing ring is tightly combined with the transparent rubber pipe so that the air tightness requirements on an RTM (Resin Transfer Molding) process technology are met.
Description
Technical field
The utility model relates to a kind of resin transfer molding process mould gum outlet snap joint that is applicable to.
Background technology
Resin transfer molding (being called for short RTM) technique is a kind of mold closing technique, low viscosity resin to be injected in the mold cavity of having placed precast body under certain pressure, make reinforcing material complete wetting, after plastic emitting, be heating and curing, thereby obtain the technique of composite.It is light that composite has quality, intensity is high, be easy to the feature of machine-shaping, and the every field such as RTM technology is good with its molded article outward appearance accordance, dimensional stability is high, low cost and other advantages is widely used in Aero-Space, warship, automobile industry become one of composite new technology that Ge great universities and colleges, enterprise competitively study.
RTM technique need to arrange gum outlet, RTM gum outlet mainly adopts pagoda joint at present, is connected and also adopts this to connect with mould, and joint is more complicated when being connected with mould, more difficult, and because RTM technique is had relatively high expectations to vacuum, below vacuum requirement-0.95bar, adopt conventional joint (pagoda joint), joint directly adopts and is threaded with pipeline, be difficult to reach quality of fit requirement, and easily cause mould or system gas leakage, be difficult to effectively guarantee RTM technology air-tightness; While reusing for the second time, more cannot guarantee the harsh requirement of RTM technique to vacuum, therefore, adopt conventional pagoda joint design, it only can use once, cannot reuse, and operation easier is larger, and efficiency is lower.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of resin transfer molding process mould gum outlet snap joint that is applicable to is provided, and can be connected fast with transparent hose, and this joint can Reusability, reduces the cost.
The purpose of this utility model is achieved through the following technical solutions: be a kind ofly applicable to the snap joint of resin transfer molding process mould gum outlet, it comprises joint body, rubber seal, locking member and nut, joint body is the two outer silk structures of screw thread, in joint body, be placed with locking member, locking member is enclosed within outside rubber seal, joint body is threaded with nut, rubber seal one end is provided with annular convex, locking member comprises cylinder and tightening, cylinder is fixedly connected with tightening, described nut one end is provided with boss, the cross section of boss is circular, one end section radius that boss is connected with nut is large compared with the other end section radius of boss, boss two ends rounding off, boss inside has an accommodating cavity, the shape of accommodating cavity is consistent with boss profile, the bottom of boss is provided with through hole, the diameter of through hole equals the external diameter of cylinder.
Described cylinder and tightening are one-body molded.
The beneficial effects of the utility model are:
1), the utility model can be connected fast with pipeline, guarantees the bonding strength of joint and transparent hose by the frictional force of rubber seal and pipeline (transparent hose or metal hose);
2), this joint can Reusability, lowers the operation easier that joint is connected with pipeline, raising joint efficiency, reduces the cost;
3), rubber seal and pipeline combine closely, and meets the air-tightness requirement of RTM technology.
Accompanying drawing explanation
Fig. 1 is that the utility model is taken structural representation apart;
Fig. 2 is the utility model boss cross-sectional view;
Fig. 3 is the utility model boss plan structure schematic diagram;
In figure, 1-joint body, 2-rubber seal, 3-annular convex, 4-locking member, 5-tightening, 6-nut, 7-boss, 8-through hole.
