The first guide rail is provided with a first guide groove, and the second guide rail is provided with a second guide groove. The first guide groove and the second guide groove are matched with the first guide rail, so that the first guide rail and the second guide rail can move horizontally relative to the mold rack 200.

[0131] In order to conveniently control the automatic control of the horizontal movement of the first guide rail and the second guide rail relative to the mold rack 200, the first conveying member further comprises: first and second horizontal driving members. The first and second horizontal driving members can be air cylinders, oil cylinders or electric cylinders, and are all installed on the mold rack 200. The first horizontal driving member is connected with the first guide rail and can drive the first guide rail to move horizontally along the first guide rail. The second horizontal driving member is connected with the second guide rail and can drive the second guide rail to move horizontally along the second guide rail.

When the first guide rail and the second guide rail move away from each other, a space can be reserved between the first guide rail and the second guide rail for the mold rack 200 to accommodate the mold set 300 to move up and down in the cavity without interference. When the required mold set 300 reaches the designated area, the first guide rail and the second guide rail move close to each other. The first guide rail and the second guide rail can be located below the required mold set 300 and directly act on the required mold set 300 to drive the required mold set 300 to come out of the accommodation cavity, and then the second conveying member conveys the required mold set 300 to the first locking member 400.

[0133] In some embodiments of the present application, the second conveying member comprises:

[0134] The third driver 570 is arranged on the mold rack 200 and can extend and retract relative to the mold rack 200.

[0135] The electromagnet 580 is connected with the third driver 570. The electromagnet 580 is used to adsorb the mold set 300 when powered on, and release the adsorption of the mold set 300 when powered off.

[0136] The controller is electrically connected with the electromagnet 580 and is used to control the power-on or power-off of the electromagnet 580.

[0138] The third driver 570 retracts, and the electromagnet 580 is powered to adsorb the mold set 300, so that the electromagnet 580 can grab the mold set 300 to move from the first locking member 400 to a designated position.

[0139] In the embodiment of the application, the third driver 570 can be a pneumatic cylinder, an oil cylinder, or an electric cylinder, and the telescopic rod of the third driver 570 can be telescopic relative to the mold rack 200.

[0141] In the above embodiment, it can be known that the first conveying member can only output the required mold set 300 to a designated position, and there is no power to continue to enter the first locking member 400. The third driver 570 and the electromagnet 580 are moved up and down to a position where the electromagnet 580 is horizontally opposite to the required mold set 300. The electromagnet 580 is driven forward by the third driver 570 at this time. The electromagnet 580 is not powered, and the electromagnet 580 is directly driven by the third driver 570 to resist the mold set 300, so that the mold set 300 is pushed from the designated position to the first locking member 400. When the mold set 300 to be withdrawn from the first locking member 400 is removed, the first locking member 400 and the second locking member 700 are both unlocked. The third driver 570 extends to the mold set 300 to be withdrawn, the electromagnet 580 is powered to adsorb the mold set 300 to be withdrawn, the third driver 570 retracts to drive the mold set 300 to be withdrawn to a designated position, the electromagnet 580 is unpowered, and the electromagnet 580 contacts and adsorbs the mold set 300 to be withdrawn. The third driver 570 continues to retract the electromagnet 580 to the original position. By adjusting the height position of the accommodating cavity of the mold rack 200, the mold set 300 to be withdrawn is opposite to the corresponding accommodating cavity. The mold set 300 to be withdrawn can be withdrawn into the corresponding accommodating cavity by the first conveying member, so as to be used for subsequent replacement.

[0142] In the embodiment of the application, the second conveying member can accurately push the mold set 300 to the first locking member 400, avoiding the position interference problem between the first conveying member and the first locking member 400. Moreover, the electromagnet 580 of the second conveying member can effectively adsorb and move the mold set 300 to be withdrawn from the first locking member 400 to a designated position, which is convenient and fast. Moreover, the second conveying member does not need to occupy a horizontal space and can be moved up and down relative to the mold rack 200, like the accommodating cavity, which is convenient and fast and saves equipment space.
