Abstract
The object of the invention is to provide a chamber for a heating press which can cope well with the height change of a composite material article. In a chamber for a heating press, upper and lower metal flanges 6, 7 are provided between upper and lower press heating plates 1, 2 and an intrusion part 11 is further formed in the lower metal flange. This intrusion part 11 is intruded into the upper metal flange 6 and the gap between the intrusion part 11 and the upper metal flange 6 is sealed by a packing 22 having a lip.
Claims11
A movable vacuum forming apparatus comprising:
- a pair of frames provided respectively to upper and lower press plates of a press apparatus via seals for surrounding a predetermined space;
- an interpenetrated portion provided at one of the frames and capable of being interpenetrated into other of the frames movably in an up and down direction;
- a seal apparatus for slidably sealing an interval between the interpenetrated portion and the other of the frames;
- and a sucking apparatus for bringing a space surrounded by the interpenetrated portion and the other of the frames under a negative pressure, wherein the seal apparatus has a main body with a flexible lip projected therefrom that seals the interval by compensating for a strain of the interpenetrated portion caused by the negative pressure of the space.
A movable vacuum forming apparatus comprising:
- one frame provided between upper and lower press plates of a press apparatus for surrounding a predetermined space provided at the upper press plate via a seal;
- a base provided at the lower press plate via a seal and having an interpenetrated portion capable of being interpenetrated to the one frame movably in an up and down direction;
- a seal apparatus for slidably sealing an interval between the interpenetrated portion of the base and the one frame;
- and a suction apparatus for bringing a space formed by the interpenetrated portion and the one frame and the upper and the lower press plates under a negative pressure, wherein the seal apparatus has a main body with a flexible lip projected therefrom that seals the interval by compensating for strain of the interpenetrated portion caused by the negative pressure of the space.
A vacuum press apparatus comprising:
- upper and lower press plates moved in an up and down direction by a predetermined drive apparatus;
- one frame attachably and detachably provided between the upper and the lower press plates for surrounding a predetermined space provided at one of the upper and the lower press plates via seal;
- a member provided between the upper and the lower press plates, provided at the other of the upper and the lower press plates via a seal and having an interpenetrated portion capable of being interpenetrated to the one frame movably in the up and down direction;
- and a seal apparatus for slidably sealing an interval between the interpenetrated portion of member and the one frame;
- and a suction apparatus for bringing a space surrounded by the interpenetrated portion and the one frame under a negative pressure, wherein the seal apparatus has a main body with a flexible lip projected therefrom that seals the interval by compensating for strain of the interpenetrated portion caused by the negative pressure of the space.
