Description

Technical Field

[0001] The invention relates to the technical field of numerical control machine tools, in particular to a mold ejector numerical control machine tool capable of automatically loading and unloading materials. Background Art

[0002] When CNC machine tools process mold ejector pin materials, they often process cylindrical mold ejector pin materials in large quantities. The process efficiency is relatively high, and the volume of the mold ejector pin materials is relatively small, which makes it inconvenient to place. As a result, the automation of the loading and unloading work of conventional loading and unloading devices is poor, and manual assistance is often required for operation. It has the disadvantages of high error rate and low efficiency, which needs to be improved.

[0003] The Chinese invention patent with announcement number CN115156976B discloses an automatic loading and unloading device for a mold ejector CNC machine tool, including a machine tool placement table, a support frame is installed on the upper surface of the machine tool placement table, and a material sorting mechanism and an adjustment mechanism are installed on the surface of the support frame. A placement groove is used to provide space for placing batch mold ejector raw materials. The contraction operation of the No. 1 electric push rod drives the angle frame and then drives the No. 1 motor and the turntable to adjust the position. The operation of the No. 1 motor drives the turntable to rotate and cooperates with the structure of the guide plate, so that the mold ejector raw materials can enter the inner side of the slideway in turn. The operation of the No. 1 electric push rod drives the inner frame to move, and the spacing of the No. 1 conveyor belt is adjusted to achieve the driving effect of the No. 1 conveyor belt. With the operation of the No. 1 conveyor belt, the mold ejector raw materials can fall into the placement cylinder in turn to complete the material sorting function.

[0004] However, the above patent still has the following shortcomings during actual use: the patent can transport the mold ejector material placed in the placement groove into the slide through the structural coordination of the turntable and the guide plate. During transportation, the mold ejector material needs to be kept in a vertical state. However, the mold ejector material is placed in the placement groove at random. The mold ejector material cannot be adjusted to a vertical state only by relying on the abutment drive of the turntable. Moreover, when the mold ejector material in a vertical state enters the slide, there is a gap between the mold ejector material and the conveying surface of the No. 1 conveyor belt. The mold ejector material is very easy to tilt in this gap, which makes it impossible for the mold ejector material to enter the placement cylinder, affecting the feeding quality of the mold ejector material. Summary of the invention

The discharge cylinder 952 is horizontally arranged on the mounting plate 953.

[0042] The feeding conveyor belt 4 works, and several mold ejector raw materials fall from the discharge end of the feeding conveyor belt 4 into the adjustment interval 9212 just below. Then, the feeding conveyor belt 4 stops working, and the sixth motor 922 drives the driving gear 9221 to rotate, the driving gear 9221 drives the gear ring 9231 to rotate, the gear ring 9231 drives the connecting pipe 923 to rotate, and the connecting pipe 923 drives the adjusting body 921 to rotate, and all the toggle plates 9211 rotate synchronously with the adjusting body 921, and the mold ejector raw materials in the adjustment interval 9212 are driven by the toggle plates 92 11 is driven to roll, and the mold ejector raw materials gradually turn into a uniform placement state when rolling on the inner wall of the feeding hopper 91. When the next adjustment interval 9212 is located directly below the discharge end of the feeding conveyor belt 4, the feeding conveyor belt 4 continues to work to convey several mold ejector raw materials to the adjustment interval 9212. After that, the mold ejector raw materials in the feeding hopper 91 gradually approach the feeding slot 9111 as the toggle plate 9211 is toggled. After that, the mold ejector raw materials in the adjustment interval 9212 can be discharged from the feeding slot 9111 in sequence.

[0043] When the adjustment interval 9212 is connected with the feed slot 9111, the sixth motor 922 stops working and the seventh motor 933 starts working. The seventh motor 933 drives the swing plate 937 to rotate, and the swing plate 937 drives the eccentric shaft 9371 to rotate synchronously.

One end of the mold ejector material discharged from the feed slot 9111 can hit the guiding slope. The guiding slope can guide this end of the mold ejector material to the feeding end of the discharge pipe 94. Since the swing cone body 936 is continuously Swing, so the mold ejector raw material also shakes synchronously when it hits the guiding inclined surface, so that the mold ejector raw material can be prevented from getting stuck, that is, the mold feed slot 9111 can be prevented from being blocked, one end of the mold ejector raw material can directly enter the upper material sorting cavity 941 through the first material guiding step 943, and then the mold ejector raw material is guided to the lower material sorting cavity 942 through the second material guiding step 944, and several mold ejector raw materials discharged from the adjustment interval 9212 can be arranged in the upper material sorting cavity 941 and the lower material sorting cavity 942 in a vertical state, and the mold ejector raw material at the lower end is blocked by the stopper 954.

[0044] Next, the discharge cylinder 952 drives the stopper 954 to move backward and forward once in the chute 945, and the lowermost mold ejector material blocked by the stopper 954 is discharged from the discharge end of the discharge pipe 94. The mold ejector material can fall into the placement tube 11 directly below, and the stopper 954 blocks the next mold ejector material. In order to allow the mold ejector material to stably enter the placement tube 11, an inner chamfer 111 is provided on the top of the placement tube 11.

This cycle continues, and the mold ejector materials in the discharge pipe 94 can be discharged in turn and fall into a placement cylinder 11. After the mold ejector materials in the discharge pipe 94 are exhausted, the sixth motor 922 continues to work, and the placement cylinder 11 drives the mold ejector materials to gradually approach the transfer mechanism 6 as the turntable 1 rotates.
