The utility model discloses set up two vacuum air cocks, reduced operating personnel's intensity of labour, also reduced the risk of vacuum bag gas leakage simultaneously, set up at the U -shaped inslot and turned round the form chain, effectively avoided the vacuum bag to get into the U -shaped groove and produced the deformation.
Description
Technical field
The utility model relates to a kind of composite material parts mould gas-guiding structure.
Background technology
Usually need after composite material parts lay-up molding to use vacuum bag cap piece, after being sealed by vacuum bag sealing joint strip, carry out compacting and solidification by the mode vacuumized.In existing known technology, two kinds are had to vacuumize mode.A kind of mode installs at least one cut hole on vacuum bag after for extracting vacuum valve and the vacuum detecting valve for vacuum in detection bag of air in bag out, vacuum valve is connected with vacuum source, after vacuum source, vacuum valve, vacuum detecting valve, vacuum bag, mould body form a confined space, in vacuum bag, air is by being pumped after vacuum valve.The shortcoming of the Vacuuming structure of this composite material parts mould is: 1. for ensureing that in vacuum bag, each region vacuum pressure is even, when accessory size is larger, need to lay more vacuum valve, the junction of vacuum valve and vacuum bag is increased, easily leaks gas; 2. because vacuum valve and vacuum detecting valve need human assistance whole process to grip, multiple operating personnel therefore in forming process, are needed to complete the operation vacuumizing and detect vacuum respectively.Another kind of mode is provided with U-shaped air guide channel between the seal area and material deposit region of composite material parts mould body, metal material cover having holes is set above U-shaped air guide channel, is provided with two bottom air guide channel and is distributed in the air guide through hole of both sides, mould diagonal angle and uses tee pipe coupling to connect vacuum valve and vacuum detecting valve.After vacuum valve is connected with vacuum source, vacuum source, vacuum valve, vacuum detecting valve, vacuum bag, U-shaped air guide channel, mould body form a confined space, and in vacuum bag, air is by being pumped after cover having holes, air guide channel, vacuum valve.The shortcoming of this composite material parts mould Vacuuming structure is that the cover having holes on U-shaped vacuum air guide channel is thinner, when part solidifies under HTHP in autoclave, cover having holes can deform owing to expanding with heat and contract with cold, cover having holes after distortion and the gap between U-shaped air guide channel become greatly, and in vacuum, vacuum bag easily enters the gap between cover having holes and U-shaped air guide channel and breaks.
Utility model content
The purpose of this utility model is to overcome when accessory size is larger, need to lay more vacuum valve, the junction of vacuum valve and vacuum bag is made to increase easy gas leakage, multiple operating personnel are needed to complete the problem of the operation vacuumizing and detect vacuum respectively in forming process, and because the cover having holes on U-shaped air guide channel is out of shape the deficiency causing vacuum bag to break, the utility model provides a kind of composite material parts mould gas-guiding structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of composite material parts mould gas-guiding structure, it comprises mould body, vacuum valve, material deposit region and vacuum bag, deposit region is placed with composite to material, material deposit region surrounding is provided with U-lag, be filled with in U-lag and turn round shape chain, vacuum valve comprises and vacuumizes valve and vacuum detecting valve, the air guide through hole matched with vacuum valve is provided with bottom U-lag, air guide through hole respectively be arranged on this external vacuum valve of mould and be connected, vacuum bag to be covered on composite and U-lag and to be tightly connected by vacuum seal adhesive tape and mould body.
Preferably, the quantity of described vacuum valve is two, and two vacuum valves are vacuumize valve and vacuum detecting valve respectively, and two vacuum valves are separately positioned on the edge, diagonal angle of mould body; Described air guide through hole is made up of air guide through hole A and air guide through hole B, air guide through hole A with vacuumize valve and be connected, air guide through hole B is connected with vacuum detecting valve.
The beneficial effects of the utility model are:
1), owing to being provided with U-lag, air guide through hole and vacuum valve on mould body, a smooth air guide path is defined in seal area, only need two vacuum valves (vacuumizing valve and vacuum detecting valve), decrease the quantity of vacuum valve and ensure that the uniformity of vacuum pressure;
2), arrange two vacuum valves, operating personnel can complete the work vacuumizing and detect vacuum, reduce the labour intensity of operating personnel, also reduce the risk of vacuum bag gas leakage simultaneously;
3), be provided with in U-lag and turn round shape chain, when material solidifies under autoclave HTHP, can not deform because of expanding with heat and contract with cold owing to turning round shape chain, effectively prevent vacuum bag and enter U-lag and produce distortion.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1-mould body, 2-vacuum bag, 3-U shape groove, 4-turns round shape chain, 5-material deposit region, 6-air guide through hole A, and 7-vacuumizes valve, 8-vacuum detecting valve, 9-air guide through hole B.
Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail, but protection domain of the present utility model is not limited to the following stated.
As shown in Figure 1, a kind of composite material parts mould gas-guiding structure, it comprises mould body 1, vacuum valve, material deposit region 5 and vacuum bag 2, material deposit region 5 is placed with composite, material deposit region 5 surrounding is provided with U-lag 3, be filled with in U-lag 3 and turn round shape chain 4, vacuum valve comprises and vacuumizes valve 7 and vacuum detecting valve 8, the air guide through hole matched with vacuum valve is provided with bottom U-lag 3, air guide through hole is connected with the vacuum valve be arranged on outside mould body 1 respectively, vacuum bag 2 to be covered on composite and U-lag 3 and to be tightly connected by vacuum seal adhesive tape and mould body 1.
