beneficial effect
Compared with prior art, right angle or negative angle place priority air extractor on a kind of plastics suction mould of the present utility model, by arranging the pipeline of Preferential adsorption in the angle of mould, extracting gases is carried out at mould Local Priority in plastic uptake process, grinding tool is avoided to fold depths uneven when vacuum suction, and produce local plastic sheet material fold or the excessively thinning phenomenon of local plastic sheet material stretching, specifically there is following beneficial effect:
1. formed on mould near right angle or low-angle burst or gully place and some absorption pipelines are set, can in plastics sucking moulding process the very first time preferentially bled in this region, make the plastic sheet softened comparatively early can be adsorbed to this region, and under avoiding the overall situation of bleeding at vacuum forming, sheet material is difficult on the mould of the parcel above-mentioned zone comparatively sealed, or there is fold at this region unbalance stress due to sheet material, or the sheet material around this region more first attaches on mould and makes sheet material be difficult to again move, this region sheet material exists
Under the effect of stronger pull of vacuum, appearance stretches phenomenon by force.
2. piston and closed valve synchronous effect are in absorption pipeline, improve the shutoff to absorption pipeline, can form negative pressure extracting gas and not easily leak gas when piston moves.
3. cushion pore to coordinate with pore bolt, slow shutoff can be realized in the process of closed jamming of valve absorption pipeline, make gas pass through cushion pore amount reduce gradually by dying down by force, avoid piston to the shock of step, also make this region for the adsorption rate of sheet material and absorption affinity from large to small simultaneously, facilitate this region sheet material to carry out position and move adjustment.
4. the rubber washer with airslide can further for closed valve shutoff produces cushioning effect, and recycling airslide can extend the time shaft that gas enters absorption pipeline, to the sheet material in this region more multiposition regulating time.
5. the template of installing this adsorbent equipment can adopt the plastic sheet of low cost also can produce superior in quality finished product, reduces the input of production, improves the yield rate of plastic uptake.
