Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The injection molding part fluidization molding machine shown in fig. 1 to 4 comprises a fixed mold 1 and a movable mold 2 for closing films and performing injection molding, wherein the fixed mold 1 is arranged on a base 3, and an injection head 4 is arranged in the movable mold 2; be equipped with the first 4 injection moulding's of cooperation mould plastics die cavity 5 in the movable mould 2, movable mould 2 still includes in 2 inner chambers of movable mould pressure platform 6 of elevating movement, is provided with elasticity in the pressure platform 6 and resets 7, and the protrusion is provided with clamp plate 8 on the membrane face that closes of movable mould 2, and clamp plate 8 is connected with pressure platform 6, and the side of pressing platform 6 and cover half 1 all is provided with connecting piece 9, connects through sprocket 10 between two at least connecting pieces 9. The injection molding processing is started after the movable mold 2 and the fixed mold 1 are combined, the injection molding part is molded after shaping and cooling, the mold is opened, the injection molding part at the moment is tightly adhered to the injection molding head 4 and the pressing plate 8, the movable mold 2 is gradually far away in the process of separating the movable mold 2 from the fixed mold 1, when the movable mold 2 rises to the maximum stroke, the movable mold 2 stops moving, as the movable mold 2 and the fixed mold 1 are connected through the chain wheel 10, the chain wheel 10 in the scheme is a chain, the structural strength is high, the chain wheel 10 is not easy to break, the chain wheel 10 is tensioned to the maximum stroke, the elastic resetting part 7 in the movable mold 2 elastically stretches in the process of rising the pressing table 6 and stores larger elastic potential energy, the elastic potential energy releasing direction of the elastic resetting part 7 is descending movement, the elastic potential energy is larger than the lifting force of the pressing table 6, the pressing table 6 descends under the acting force of the elastic resetting part 7, the injection molding head 4 is static at the, so accomplished the unloading work of injection molding for the injection molding is with moulding plastics head 4 steady separation, guarantees the injection molding quality, safety in production.
