Described upper formation die core and compacted under core rod adopt high-strength alloy mould steel, by the forging heat treatment steps such as roughing, modified and fine finishining rear surface nitriding of annealing, guarantee the existing very high intensity of this mould and hardness, also guarantee that this mould tool has good wearability simultaneously.
Described top mold frame and lower mold holder adopt the mould bases of the guiding of rolling, and to guarantee kinematic accuracy and the service life of mould bases, are conducive to the quick-replaceable of mould simultaneously and shorten the design and manufacture cycle.
Described a kind of water hole or wind-tunnel cellular board moulding composite die, thereby by changing difform upper formation die core and compacted under core rod, realize the cellular board that strikes out difformity wavestrip material, comprise square wave, square wave, sine wave, circular arc ripple and triangular wave.
The beneficial effect of water hole described in the utility model honeycomb cellular board mould:
1. realize can be in batches that molding of the cellular board of super wide foil material (thickness is no more than 0.1mm, and width surpasses 500mm) and super large slenderness ratio (ratio approaches 100) is lightweight, quality is high, honeycomb even thickness, wind, water hole honeycomb cellular board that tolerance is less;
2. this mould guarantees after moulding between honeycomb duct that the depth of parallelism of central axis and the perpendicularity of honeycomb duct central axis and honeycomb duct end face meet the demands;
3. can realize the moulding of various shape wavestrip material;
4. use this mould can improve greatly production effect, reduce workman's labour intensity.
