DETAILED DESCRIPTION

The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

1-7 , a demoulding device for a mold for metal parts processing includes a molding box 1 , in which a connecting plate 2 is sealingly and slidably connected, and two supporting legs 3 are fixedly connected to the lower end of the molding box 1 , and the two supporting legs 3 are symmetrically distributed along the center of the molding box 1 .

A lifting screw 15 is rotatably connected to the bottom of the molding box 1, and a lifting nut 18 is threadedly connected to the lifting screw 15. A plurality of lifting rods 19 are fixedly connected to the upper end of the lifting nut 18, and one end of the lifting rod 19 away from the lifting nut 18 is fixedly connected to the lower end of the connecting plate 2;

There are two brackets 12 slidably connected in the molding box 1, and a plurality of Z-shaped plates 13 are fixedly connected to the brackets 12. A vibrating ball 14 is fixedly connected to one end of each Z-shaped plate 13 away from the bracket 12. A moving device for continuously moving the bracket 12 up and down is installed at the bottom of the molding box 1. Two telescopic rods 7 are fixedly connected to the bottom of the molding box 1, and the telescopic end of each telescopic rod 7 is fixedly connected to the adjacent bracket 12. It should be noted that by providing the telescopic rod 7, on the one hand, after the telescopic end of the telescopic rod 7 is fixedly connected to the bracket 12, the bracket 12 can be limited so that the bracket 12 can only move up and down in the vertical direction. On the other hand, the movement of the bracket 12 can also be made more stable.

The moving device includes a turntable 17 rotatably connected to the bottom of the molding box 1, a plurality of arc grooves 8 are provided on the upper end surface of the turntable 17, and the plurality of arc grooves 8 are arranged at equal intervals along the circumference of the turntable 17, a servo drive motor 4 is fixedly installed at the lower end of the molding box 1, and the output shaft of the servo drive motor 4 is fixedly connected to the lower end of the turntable 17, and the lifting screw 15 is fixedly connected to the upper end of the turntable 17. Specifically, when the servo drive motor 4 is started, it can drive the turntable 17 and the lifting screw 15 to rotate synchronously.

Referring to Fig. 5, a sleeve 9 is provided on the outer side of the lifting screw 15, and the lower end of the lifting screw 15 passes through the sleeve 9 and is connected to the turntable 17. Two rotating rods 10 are fixedly connected to the side wall of the sleeve 9. The two rotating rods 10 are symmetrically arranged along the axis of the sleeve 9. The end of the rotating rod 10 away from the sleeve 9 is rotatably connected to the roller 11, and the roller 11 rolls along the upper end surface of the turntable 17. The lower end of the bracket 12 is fixedly connected to the rotating rod 10. It should be noted that the roller 11 rolls along the upper end surface of the turntable 17. When the turntable 17 rotates, the roller 11 passes through each arc groove 8. The roller 11 moves to the bottom concave part of the arc groove 8 for a while, and then moves to the upper end plane of the turntable 17. In this way, the roller 11 can move in the vertical direction, thereby driving the upper bracket 12 to move up and down through the rotating rod 10.

4, a condenser 23 is fixedly connected to the lower end of the connecting plate 2, and one end of the condenser 23 is connected to the water inlet pipe 5, and the other end of the condenser 23 is connected to the water pump 21, and a water supply assembly for supplying water to the condenser 23 is installed in the water pump 21. It should be noted that by providing the condenser 23 and the water supply assembly, cooling water can be continuously input into the condenser 23 through the water supply assembly. When the cooling water flows inside the condenser 23, it can quickly absorb the heat of the molded metal parts cast and processed above the connecting plate 2, so as to quickly cool down the molded metal parts, thereby facilitating subsequent assembly or packaging for storage, which also improves the production and processing efficiency of the entire metal parts.

7, the water supply assembly includes a piston 16 that is sealed and slidably connected in a water pumping cylinder 21, a water outlet pipe 6 that communicates with the inside of the water pumping cylinder 21 is fixedly connected to the side wall of the water pumping cylinder 21, a water inlet check valve is installed in the water inlet pipe 5, a water outlet check valve is installed in the water outlet pipe 6, a driving rod 20 is fixedly connected to the lower end of the piston 16, the lower end of the driving rod 20 is fixedly connected to the bracket 12, the water pumping cylinder 21 is fixedly connected to the lower end of the connecting plate 2, a spring 22 is fixedly connected to the lower end of the water pumping cylinder 21, and the lower end of the spring 22 is fixedly connected to the bracket 12. It should be noted that, as shown in FIG7, the driving rod 20 slides through the bottom of the water pumping cylinder 21 and forms a through hole, and the through hole and the driving rod 20 are provided with gaps around, so that the lower space of the piston 16 is connected to the outside, which enables the piston 16 to move up and down without being hindered by the lower air pressure.

Furthermore, the water inlet one-way valve restricts the water to flow in one direction only from the water inlet pipe 5 to the condenser 23, while the water outlet one-way valve restricts the water to flow in one direction only from the water pumping cylinder 21 to the water outlet pipe 6. Therefore, after the piston 16 moves downward to generate negative pressure, water can only be sucked from the water inlet pipe 5 into the condenser 23, and then sucked into the water pumping cylinder 21 by the condenser 23. When the piston 16 moves upward, the water in the water pumping cylinder 21 can be squeezed out from the water outlet pipe 6.

In the present invention, when demolding is required, the servo drive motor 4 can be controlled to drive the lifting screw 15 to rotate in the forward direction. At this time, the lifting nut 18 can be moved upward under the transmission action of the thread, and the lifting nut 18 can push the connecting plate 2 upward through the lifting rod 19. Since the servo drive motor 4 actively provides an output torque to the lifting screw 15, the lifting nut 18 can provide a large lifting force to the connecting plate 2 on the upper side through the lifting rod 19, so the connecting plate 2 can effectively push the metal parts cooled and formed on the upper side to move upward and separate from the molding box 1 (equivalent to the lower mold in the mold).

In addition, when the lifting screw 15 rotates, it will also drive the turntable 17 to rotate. The sleeve 9 is fixedly connected to the bracket 12 through the rotating rod 10, and the bracket 12 is fixedly connected to the bottom of the forming box 1 through the retractable telescopic rod 7. Therefore, the sleeve 9 will not rotate, and the positions of the rotating rod 10 and the roller 11 on both sides of the sleeve 9 remain unchanged. When the turntable 17 rotates, the arc grooves 8 above the turntable 17 pass through the wheel surface of the roller 11 in sequence, and the roller 11 moves along the top of the turntable 17. When the roller 11 moves to the concave part of the arc groove 8, the spring 22 on the upper side can push the bracket 12, the rotating rod 10 and the roller 11 to move downward, so that the roller 11 contacts the inner bottom of the arc groove 8. When the roller 11 leaves the upper end plane of the conductive turntable 17 of the arc groove 8, the roller 11 rises and drives the bracket 12 to move upward through the rotating rod 10. Therefore, when the roller 11 walks around the upper end of the turntable 17, the bracket 12 can be continuously moved up and down under the joint action of the spring 22.

During the up and down reciprocating movement of the bracket 12, the Z-shaped plates 13 and the vibrating balls 14 will be driven to move up and down synchronously. Then, the vibrating balls 14 will continuously knock on the surroundings of the connecting plate 2 during the up and down movement, forcing the metal parts above the connecting plate 2 and the small connecting parts inside the molding box 1 to break, thereby greatly reducing the resistance of the connecting plate 2 to upward demoulding and improving the demoulding efficiency.

Furthermore, as shown in Figures 3 and 7, when the bracket 12 moves downward, the driving rod 20 is pulled downward, and the driving rod 20 pulls the piston 16 downward, so that the water inlet pipe 5 and the water outlet pipe 6 are both connected to a water tank. When the piston 16 moves downward, the space on the upper side increases, and negative pressure can be actively generated to suck the cooling water in the water tank along the water inlet pipe 5 into the condenser 23, and then sucked into the water pump 21 through the condenser 23. When the bracket 12 moves upward, the cooling water sucked into the water pump 21 and on the piston 16 can be sucked into the condenser 23. The cooling water on the side is discharged into the water tank along the water outlet pipe 6. In this way, when the bracket 12 moves up and down, it can drive the piston 16 to move up and down continuously, so as to continuously flow the cooling water along the pipeline direction of the water inlet pipe 5-condenser 23-water pump 21-water outlet pipe 6. When the cooling water flows through the condenser 23, it can quickly absorb the heat of the formed metal parts above the connecting plate 2 and dissipate it. In this way, the formed metal parts can be quickly cooled down to facilitate subsequent assembly, packaging and warehousing operations.

After demoulding is completed, the servo drive motor 4 can drive the turntable 17 and the lifting screw 15 to rotate in the opposite direction, so that the lifting nut 18 can drive the lifting rod 19 and the connecting plate 2 to move down and reset, and the casting process of the next metal part can be carried out.

The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
