Detailed Description
The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.
Referring to fig. 1-3, the present invention provides a technical solution: the exhaust structure of the polyurethane foaming mold comprises an exhaust valve body 1, wherein the exhaust valve body 1 comprises an air inlet pipe 2 and an air outlet pipe 3, the air inlet pipe 2 and the air outlet pipe 3 are respectively welded below and above the exhaust valve body 1, and the air inlet pipe 2 and the air outlet pipe 3 are communicated with the exhaust valve body 1;
the air inlet pipe 2 comprises a main valve 8 connected to the left side of the air inlet pipe 2 through a flange, a circular ring 9 is clamped in the air inlet pipe 2, four embedded pieces II 13 are symmetrically embedded in the left side and the right side of the upper side and the lower side of the circular ring 9, a vent pipe 10 penetrates through the circular ring 9, the vent pipe 10 is movably connected with the air inlet pipe 2 through the circular ring 9, ring rings 11 are fixed at the upper end and the lower end of the vent pipe 10, the diameter of each ring 11 is larger than the inner diameter of the circular ring 9, the height of the vent pipe 10 is larger than the distance between the bottom of the circular ring 9 and the bottom of the air inlet pipe 2, the outer wall of each ring 11 abuts against the inner wall of the air inlet pipe 2, embedded pieces I12 are embedded in the left end and the right end of the inner side of each ring 11, the embedded pieces I12 correspond to the embedded pieces II 13 in position, the embedded pieces;
when the foaming mould is exhausted, the lower ring 11 can be pushed upwards firstly, so that the first embedded sheet 12 at the inner side of the lower ring 11 and the second embedded sheet 13 at the bottom of the circular ring 9 are sucked together, the vent pipe 10 is temporarily stabilized at a moving point, then the air inlet pipe 2 is connected to the air outlet of the foaming mould, then the main valve 8 is opened, the air in the foaming mould is guided into the air outlet valve body 1 through the air inlet pipe 2 and is filtered through the filter screen 14, when the filter screen 14 is used for a long time and needs to be cleaned, the lower ring 11 is pulled downwards until the upper ring 11 is close to the top of the circular ring 9, the first embedded sheet 12 at the inner side of the upper ring 11 and the second embedded sheet 13 at the top of the circular ring 9 are sucked together, can make the breather pipe 10 lower part stretch into to intake pipe 2 bottom, and the filter screen 14 will stretch out to intake pipe 2 bottom in the lump to need not to pull down filter screen 14 and just clear up.
Secondly, after gas discharges to the exhaust valve body 1 in, can unscrew closing cap 4, the air will be discharged from outlet duct 3, after the air current diminishes gradually, again with closing cap 4 lid back to the original place, then open sub valve 7, make the air current of leading-in outlet duct 3 discharge to gasbag 6 in making gasbag 6 swell through side pipe 5, after the air in the foaming mould discharges and finishes main valve 8 and sub valve 7 close together, then unscrew side pipe 5, and open sub valve 7 once more and discharge the air in the gasbag 6 can, can effectively reduce the probability that the air current leaked to in the foaming mould, influence when using to the foaming mould is less, and the practicality is better.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
