The outside of slider is fixed with the handle, makes things convenient for personnel to pull the slider removes.
The bottom of the slider and the bottom of the base slider through hole are provided with corresponding dovetail grooves, and two ends of the dovetail grooves at the bottom of the base slider through hole are provided with limiting structures, so that the slider can slide out of the base while sliding is met.
Working process
The weighed mould pressing materials are loaded into the inner cavity of the outer die, the cylindrical pressure head at the lower end of the upper die is controlled by a press machine to be inserted into the inner cavity of the outer die, and the mould pressing materials are pre-pressed into a cake-shaped blank; after pressing is finished, the sliding block slides outwards to leave the descending channel, the upper die is controlled to continue to press downwards until the cake-shaped blank completely enters the sliding block through hole of the base, and the cake-shaped blank and the adjusting plate are dismounted from the lower end of the upper die from the other side of the sliding block through hole; and pushing the sliding block back to reset, and then placing the adjusting plate in the inner cavity of the outer die again, so that the prepressing of the next die pressing material can be repeated.
Has the advantages that:
the prepressing forming device has simple structure and simple and convenient operation, and can be directly added into a cake-shaped blank when a product is formally pressed by pressing the mould pressing material into the cake-shaped blank in advance; after the mould pressing material is pre-pressed, the air content is low, so that the heat transfer is accelerated, the preheating and curing time can be shortened, more bubbles in the product can be avoided, and the quality of the product can be improved; and the cake-shaped blank is directly added, so that the compression rate of raw materials is reduced, a feeding chamber of the die is reduced, and the structure of the die can be simplified.
