Description

Technical Field

[0001] The utility model belongs to the technical field of molds, and in particular relates to a continuous in-mold floating roller feeding mechanism. Background Art

[0002] Moulds are various moulds and tools used in industrial production to obtain the required products by methods such as injection moulding, blow moulding, extrusion, die casting or forging, smelting, stamping, etc.; in the mould processing link, the raw material plate needs to be stamped first. The commonly used mould feeding is divided into manual feeding and automatic feeding. In the continuous mould of the prior art, due to the large number of divided plates, after the strips are cut on both sides and in the middle of the material strip, the material head will warp upward due to the stress release of the material, resulting in the material head not being able to enter the guide plate of the next workstation well, resulting in the inability to continue production, damage to the material strip, and even damage to the mould.

[0003] To this end, a floating guide block feeding continuous die with the announcement number "CN211304472U" includes an upper die and a lower die, the lower die includes a lower die base and a lower template, the lower template is provided on the lower die base, floating plates are provided on both sides of the lower template, a guide pin is provided below the floating plate, the guide pin is movably arranged on the lower die base, and a floating plate spring is provided on the guide pin jacket between the floating plate and the lower die base; a movable guide block is provided above the floating plate, the movable guide block is provided with a lower groove, a guide screw is provided in the lower groove, the guide screw includes a nut, a screw rod and a light rod between the nut and the screw rod, and the light rod is movably inserted into the bottom of the lower groove.

The elastic floating telescopic member 4 is hidden and fixed in the hidden hole 12, so that the elastic floating telescopic member 4 is more firmly and stably in the hidden hole 12, and one end of the elastic floating telescopic member 4 is fixed to the bottom side of the lower mold floating plate 2, so that the lower mold floating plate 2 can lift and suspend the aluminum material, reducing the aluminum The material is scratched, a positioning groove 13 is opened at the center of the surface of the lower mold floating plate 2, which can make the lower mold floating plate 2 move down and be positioned on the stamping core of the lower mold 1 by using the positioning groove 13, and strip-shaped through grooves 14 are penetrated on both sides of the surface of the lower mold floating plate 2, so that the roller 3 is rotated inside the through groove 14 to transport the aluminum material, and bearings 15 are provided on both side walls inside the through groove 14.

At this time, the cylinder 9 pushes the guide movable plate 6 to move downward on the guide vertical rod 7, and the downward movement of the guide movable plate 6 drives the upper die 5 to move downward to close the die with the lower die 1 for stamping. At the same time, the downward movement of the upper die 5 pushes the lower die floating plate 2 to move downward, and the elastic floating telescopic member 4 is retracted to the hidden hole 12, so that the lower die floating plate 2 contacts and fits the surface of the lower die, and the groove 14 passes through the bearing member 1 5, the bottom of the rotating roller 3 enters into the buffer chamber 16, so that the upper die 5 can punch the aluminum material fed on the lower die floating plate 2. After the punching is completed, the upper die 5 quickly moves up, and the elastic floating telescopic member 4 extends upward to lift the lower die floating plate 2 and suspend it on the vertical upper end of the lower die 1, so that the aluminum material can be kept away from the lower die 1 and continue to be conveyed by the roller 3, which can reduce the problem of friction and scratches between the aluminum material and the lower die 1 and the lower die floating plate 2. In addition, through the continuous punching of the mold, the aluminum material is continuously fed into the lower die 1 through the rotating roller 3, thereby improving the quality of the aluminum material conveying and the feeding efficiency.
