Description

TECHNICAL FIELD

[0002] Casting is a method of pouring liquid metal into a casting cavity adapted to the shape of the part, and after cooling and solidification, a part or blank is obtained. After pouring metal liquid in the mold, cooling is needed before opening to take out the formed metal part.

[0003] When casting an automobile curved metal plate, metal liquid is poured into the mold after clamping through the liquid injection pipe. After the curved metal plate is cooled and formed, the mold is opened.

[0045] The working principle of the second embodiment is as follows:

[0046] In the initial state, the corresponding liquid injection pipe 11 on the uppermost upper die 10 is located directly below the casting liquid delivery pipe; the control lifting structure drives the casting liquid delivery pipe to be inserted into the liquid injection pipe 11; the control valve is started to pour a certain amount of metal liquid between the upper die 10 and the annular bottom die 6 in the closed die state; the control lifting structure drives the casting liquid delivery pipe to be separated from the liquid injection pipe 11; and the pouring is completed.

[0047] The driving motor 21 is started to drive the rotating shaft 24 to rotate, thereby driving the rotating lever 23 on the casting part 2 to rotate a certain angle in the sleeve 19, so that the annular bottom die 6 is rotated and moved by a certain angle; then the driving motor 21 is stopped, and the position conversion of each group of upper dies 10 on the annular bottom die 6 is completed.

[0048] In the process of rotating and converting the position of the annular bottom die 6, the bevel gear 33 close to the first bevel gear 34 rotates and walks on the first bevel gear 34, thereby driving the lead screw 29 to rotate, thereby driving the corresponding upper die 10 to slide away from the annular bottom die 6, and the mold is opened; in this process, the cooled bent metal plate 12 is clamped between the first arc-shaped top plate 40 and the second arc-shaped top plate 42, the ear lever 13 is separated from the liquid injection pipe 11, the ball head 44 on the corresponding ejection part 15 slides from the planar end of the guide pipe 4 to the curved guide groove 5, and the clamped bent metal plate 12 is ejected from the avoiding groove 14 under the elastic reset action of the reset spring 38; in the process of being ejected, the ear lever 13 gradually slides close to the cutting knife 17, and when the bent metal plate 12 is ejected to the position where the ear lever 13 contacts the fixed cutting knife 17, the ear lever 13 is cut off, and the cut-off ear lever 13 slides down along the second arc-shaped material guide plate 49 and is collected.

[0049] When the ball head 44 slides to the most concave part of the curved guide groove 5, the annular bottom die 6 stops rotating, at this time, the bent metal plate 12 clamped between the first arc-shaped top plate 40 and the second arc-shaped top plate 42 is completely slid out of the annular bottom die 6, the control starts the electric push rod 46 to drive the top rod to rise and eject the bent metal plate 12 from between the first arc-shaped top plate 40 and the second arc-shaped top plate 42, the bent metal plate 12 slides along the first arc-shaped guide plate 48 and is collected, realizing automatic discharging and improving work efficiency.

[0050] After the discharging is completed, with the rotation of the annular bottom die 6, the corresponding bevel gear 33 is driven to rotate on the second bevel gear plate 35, thereby driving the lead screw 29 to rotate reversely and reset, thereby driving the corresponding upper die 10 to slide towards the direction close to the annular bottom die 6, and the mold closing is completed.

[0051] Embodiment three, please refer to Figures 1-12 , the third embodiment is improved on the basis of the first embodiment, specifically, the side die plate 7 and the corresponding conical guide plate 8 are both hollow structures and are communicated with each other; the conical guide plate 8 is penetrated and communicated at both ends to be provided with a wind pipe 50; the guide pipe 4 is fixed with an extension frame 51 on the side; the extension frame 51 is respectively fixed with a semi-annular air supply pipe 52 and an annular air exhaust pipe 53 which are coaxially arranged; the semi-annular air supply pipe 52 and the annular air exhaust pipe 53 are both provided with a plurality of air vents 54 which are adapted to the wind pipe 50 on the side; the semi-annular air supply pipe 52 is communicated with a fan cover 55 on the side; the fan cover 55 is internally installed with an air extractor which is electrically connected with the output end of the controller 18.

[0053] After the pouring is completed, with the rotation of the annular bottom die 6, the corresponding wind pipe 50 is rotated to the semi-annular air supply pipe 52 to be communicated with the corresponding air vent 54, the control starts the air extractor to suck the external cold air into the semi-annular air supply pipe 52, the flowing cold air transports the heat in the corresponding side die plate 7 and the corresponding conical guide plate 8 to the annular air exhaust pipe 53, thereby improving the cooling efficiency, the air which completes the heat exchange is exhausted through the corresponding air vent 54 on the annular air exhaust pipe 53 into the side die plate 7 and the corresponding conical guide plate 8 after the discharging and mold closing, thereby preheating the mold after the discharging and mold closing, preventing the mold after the cooling from directly contacting the molten metal liquid, causing material defects due to the large temperature difference, and improving the service life of the mold.
