Preferably, the axle Central Symmetry of described first teeth portion and the second teeth portion opposed gear is arranged, and multiple first leader pin and multiple second leader pin arrange with homonymy symmetric mode.
Rotate to prevent leader pin and cause teeth crossbite, described first leader pin, Second Edge nail on and are provided with limited block.
Concrete, described limited block is connected with the first leader pin or the second leader pin buckle, and described dynamic model part or cover half part offer the accommodating spacing space for holding limited block.
In order to prevent teeth at the die sinking direction superior displacement of mould, described first leader pin, the second leader pin are fixed in dynamic model part, cover half part respectively by a briquetting.
Improve as one of the present utility model, described fixed block is arranged on the outside portion of mid portion, and described fixed block has oil dripping mouth.
The utility model has the following advantages and beneficial effect compared to existing technology:
1, the utility model is by directly on the leader pin of mould inside structural member, through the mode of processing and gear reasonable coordination, the synchronous die sinking to laminated mould controls, thus complicated synchronous mold-opening structure is simplified, the improved efficiency of folding mould, owing to not needing to increase other external hanging modules again, cost is minimized, and space utilization promotes greatly.
2, due to only processing process on the structural member of mould itself, namely leader pin can play synchronous die sinking effect, can play guide effect again, and stationarity and the net synchronization capability of the action of opening and closing mould are promoted.
