Abstract
Plastics tray mould thimble board bearing guide mechanism, including mould cover half compound plate and movable mould compound plate, install hot runner plate under the cover half compound plate, install the fixed die plate under the hot runner plate, install two mould feet on the movable mould compound plate, install the movable mould board on two mould feet, set up thimble board and last thimble board down between two mould feet, the inside wall of two mould feet on respectively set up linear guide, respectively set up the straight line on the both sides lateral wall face of thimble board and last thimble board down and lead the slider, the straight line is led the slider and is cooperated with linear guide. Its advantages are: the linear guide rail is arranged on the mold leg, and the weight of the lower ejector pin plate and the upper ejector pin plate is transmitted to the mold leg through the linear guide rail, so that the mold leg can bear more weight, a guide pillar is not needed, and the problems of deformation and the like do not exist; and the linear guide rail is matched with the linear guide sliding block, so that the friction is smaller, the lower ejector plate and the upper ejector plate are ejected more smoothly, the service life is longer, the maintenance frequency is reduced, and the production efficiency is improved.
Description
Technical Field
The utility model relates to a plastics tray mould thimble board bearing guiding mechanism belongs to the injection mold field.
Background
The plastic tray is large in volume, so that the injection mold of the plastic tray is also large in volume and heavy in weight. After the plastic tray is injection molded, the push rod is pushed by the power of the injection molding machine, the push rod drives the ejector plate of the mold, the ejector plate drives the ejector pins to eject the plastic tray out of the mold, and then the plastic tray is taken away by workers. Traditional plastics tray mould thimble board is when ejecting, by guide pillar direction and bearing, and in actual production, the mould crouches on one's side and places on the injection molding machine, and the guide pillar is bearing the weight of thimble board, and when ejecting, the guide pillar is because the thimble board takes place the friction, consequently, leads to the guide pillar to warp very easily and wearing and tearing, needs often to change and leads to, increases the maintenance cost, influences production efficiency.
Disclosure of Invention
The utility model aims at overcoming prior art's shortcoming, providing one kind and adopting linear guide direction and bearing, the friction is little, long service life reduces the maintenance, saves the cost, improves production efficiency's plastics tray mould thimble board bearing guiding mechanism.
The utility model discloses plastics tray mould thimble board bearing guiding mechanism's technical scheme is: the hot runner plate is installed below the fixed die compound plate, the fixed die plate is installed below the hot runner plate, two die feet are installed on the movable die compound plate, the movable die plate is installed on the two die feet, a lower ejector plate and an upper ejector plate are arranged between the two die feet, the hot runner plate is characterized in that linear guide rails are respectively arranged on the inner side walls of the two die feet, linear guide blocks are respectively arranged on the two side wall surfaces of the lower ejector plate and the upper ejector plate, and the linear guide blocks are matched with the linear guide rails.
The utility model discloses a plastics tray mould thimble board bearing guiding mechanism, lower thimble board and last thimble board adopt linear guide and sharp slider cooperation mode ejecting (remove), and its advantage has: the linear guide rail is arranged on the mold leg, and the weight of the lower ejector pin plate and the upper ejector pin plate is transmitted to the mold leg through the linear guide rail, so that the mold leg can bear more weight, a guide pillar is not needed, and the problems of deformation and the like do not exist; and the linear guide rail is matched with the linear guide sliding block, so that the friction is smaller, the lower ejector plate and the upper ejector plate are ejected more smoothly, the service life is longer, the maintenance frequency is reduced, and the production efficiency is improved.
The utility model discloses a plastics tray mould thimble board bearing guiding mechanism, two mould foot inside walls on respectively set up two linear guide, respectively set up corresponding straight line guide block on lower thimble board and the last thimble board, it is more steady to remove when ejecting.

Fig. 1 is the structure schematic diagram of the plastic tray mould ejector plate bearing guide mechanism of the utility model.
Detailed Description
The utility model relates to a plastics tray mould thimble board bearing guiding mechanism, as shown in figure 1, including mould cover half compound plate 1 and movable mould compound plate 2, install hot runner plate 3 under the cover half compound plate, install fixed die plate 4 under the hot runner plate, install two film feet 5 on the movable mould compound plate, install movable mould board 6 on two film feet, set up down thimble board 7 and last thimble board 8 between two film feet 5, the inside wall of two film feet 5 on respectively set up linear guide 9, respectively set up the straight line on thimble board 7 and the both sides wall face of last thimble board 8 down and lead slider 10, the straight line is led slider 10 and is matched with linear guide 9. Ejector plate 7 and last ejector plate 8 adopt linear guide 9 and the sharp slider 10 cooperation mode ejecting (remove) down of this scheme, and its advantage has: the linear guide rail is arranged on the mold leg, and the weight of the lower ejector pin plate and the upper ejector pin plate is transmitted to the mold leg through the linear guide rail, so that the mold leg can bear more weight, a guide pillar is not needed, and the problems of deformation and the like do not exist; and the linear guide rail is matched with the linear guide sliding block, so that the friction is smaller, the lower ejector plate and the upper ejector plate are ejected more smoothly, the service life is longer, the maintenance frequency is reduced, and the production efficiency is improved. Two linear guide rails 9 are respectively arranged on the inner side walls of the two mold feet 5, and corresponding linear guide sliders 10 are respectively arranged on the lower ejector plate 7 and the upper ejector plate 8, so that the ejection is more stable in movement.
