Description

Technical Field

[0001] The present invention relates to the technical field of die production equipment, and specifically relates to an automatic die sheet removing mechanism. Background Art

[0002] Lost foam casting is a new type of casting technology. Different from traditional casting technologies, it is more convenient and produces less pollution. Lost foam casting generally includes several steps such as foaming, mold making, gluing, assembling, dip coating, post finishing, melting, and pouring. In the mold making process, the made die sheet needs to be taken out of the mold making machine in time. The existing mold making machines lack an automatic material taking device and use manual material taking for blanking. Because the mold making machine cannot cool down instantly after making the die sheet, and manual taking is prone to uneven or excessive force, resulting in deformation of the mold or many uneven points, thereby causing damage to the already made die sheet, increasing the artificial waste rate, bringing unnecessary losses to the enterprise. At the same time, the taken-out mold is cooled naturally, and the heat dissipation efficiency is relatively slow, thus bringing inconvenience to the staff. Summary of the Invention

Detailed implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Please refer to Figures 1-6 , in the embodiment of the present invention, an automatic die sheet taking-out mechanism includes a support floor footing 1, an air pump 8, and a pressure distribution device 7. The working principles and structures of the air pump 8 and the pressure distribution device 7 are prior arts, so no detailed description will be given here. And the air pump 8 is a rodless cylinder, thus reducing the floor area of the cylinder and saving the installation space of the cylinder. The upper surface of the support floor footing 1 is fixedly connected with a column 2. The upper end surface of the column 2 is horizontally and fixedly connected with a cross beam 5. The upper surface of the cross beam 5 is slidably connected with a moving support plate 3. A moving box 15 is arranged below the moving support plate 3. The air pump 8 is fixedly connected in the moving box 15. And a rotating shaft 12 is arranged below the air pump 8. One end of the rotating shaft 12 is rotatably connected to the inner side wall of the moving box 15. The other end of the rotating shaft 12 penetrates through the moving box 15 and is fixedly connected with a suction cup support plate 14;

[0026] The pressure distribution device 7 is fixedly connected to the suction cup support plate 14. And vacuum suction cups 13 are equidistantly and fixedly connected to the suction cup support plate 14. The vacuum suction cups 13 cooperate with the pressure distribution device 7.

[0027] A horizontally arranged strip-shaped through hole 16 is opened on the cross beam 5. A connecting rod 6 is slidably connected in the strip-shaped through hole 16. The upper end surface of the connecting rod 6 is fixedly connected to the lower surface of the moving support plate 3. The lower end surface of the connecting rod 6 is fixedly connected to the upper surface of the top plate of the moving box 15 to facilitate the fixed connection of the moving box 15 to the moving support plate 3.

[0028] Guide rails 4 are fixedly connected to the opposite side walls of the strip-shaped through hole 16. A rotating rod 17 is rotatably connected to the connecting rod 6. Both ends of the rotating rod 17 are fixedly connected with pulleys 18. The pulleys 18 are rollingly connected in the guide rails 4 to facilitate the movement of the connecting rod 6 driving the moving box 15.

[0029] A rack 9 is fixedly connected to the air pump 8, and a gear 10 is fixedly connected to the rotating shaft 12. The gear 10 meshes with the rack 9, facilitating the air pump 8 to drive the movement of the rack 9, thereby driving the rotation of the rotating shaft 12 through the gear 10.

[0030] A receiving groove 19 is formed on the side wall of the suction cup support plate 14 away from the hollow suction cup 13. The pressure distribution device 7 is fixedly connected in the receiving groove 19, and a pipeline 20 is fixedly connected to the vacuum suction cup 13. One end of the pipeline 20 away from the vacuum suction cup 13 is communicated with the pressure distribution device 7, facilitating the fixed connection of the pressure distribution device 7 to the suction cup support plate 14.

[0031] A cavity 21 is formed in the suction cup support plate 14. A plurality of through holes 22 are formed on the side of the cavity 21 close to the vacuum suction cup 13. The through holes 22 cooperate with the vacuum suction cup 13. The cavity 21 is convenient for loading clear water, and the through holes 22 are convenient for the outflow of water.

[0032] A moving plate 23 is arranged in the cavity 21. A plurality of rubber plugs 24 are fixedly connected to the side wall of the moving plate 23 close to the through holes 22. The rubber plugs 24 are inserted into the through holes 22, and a plurality of circular through holes 25 are formed on the moving plate 23. The circular through holes 25 are arranged staggered with the rubber plugs 24, facilitating the control of the opening and closing of the through holes 22.

[0033] A limiting rod 26 is fixedly connected to the side wall of the moving plate 23 away from the rubber plug 24. A spring 27 is sleeved on the limiting rod 26. One end of the spring 27 is fixedly connected to the side wall of the moving plate 23, and the end of the spring 27 away from the moving plate 23 is fixedly connected to the side wall of the cavity 21. Due to the tension of the spring 27, the moving plate 23 is attached to the side wall of the cavity 21 where the through holes 22 are formed, thereby facilitating the insertion of the rubber plugs 24 into the through holes 22.

[0034] A connecting plate 28 parallel to the suction cup support plate 14 is arranged on one side of the pressure distribution device 7. The connecting plate 28 cooperates with the pressure distribution device 7, and the end of the limiting rod 26 away from the moving plate 23 penetrates through the side wall of the cavity 21 and is fixedly connected to the side wall of the connecting plate 28. The connecting plate 28 cooperates with the air outlet end of the pressure distribution device 7. By the discharge of the gas from the pressure distribution device 7, the connecting plate 28 is pushed to one side, thereby driving the rubber plug 24 to move away from the through hole 22 through the moving plate 23, causing the through hole 22 to open.

[0035] A feed hole 29 is formed on the side wall of the cavity 21 opposite to the through hole 22. A piston 11 is inserted into the feed hole 29, facilitating the injection of clear water into the cavity 21.

[0036] When the present invention is in use, the supporting floor feet 1 are fixed to the ground by means of existing technologies such as screws and are located on one side of the molding machine. Then, one end face of the cross beam 5 far from the column is fixed to the molding machine by screws and the like in the existing technology. Next, the movable support plate 3 is connected to a driving device such as a hydraulic rod in the existing technology. The piston 11 is pulled out, and clean water is injected into the cavity 21. When it is necessary to take out the molded mold, the air pump 8 is started, so that the air pump 8 drives the movement of the rack 9, and thus, through the meshing of the rack 9 and the gear 10, the rotation of the gear 10 is driven. Then, the rotation of the suction cup support plate 14 is driven by the rotating shaft 12, so that the vacuum suction cup 13 faces the molded mold. The pressure distribution device 7 is turned on, so that the pressure distribution device 7 pumps out the air in the vacuum suction cup 13, so that the vacuum suction cup 13 adsorbs on the molded mold. The air pumped out by the pressure distribution device 7 is discharged from one side of the connecting plate 28, and the connecting plate 28 is blown to the side far from the pressure distribution device 7 by the gas, so that the position of the moving plate 23 is driven by the limiting rod 26, and the rubber plug 24 is moved away from the through hole 22, so that the clean water in the cavity 21 flows to the molded mold through the through hole 22, thereby improving the heat dissipation efficiency of the molded mold. After the pressure distribution device finishes exhausting the air, the moving plate 23 is pushed to the side of the through hole 22 by the tension of the spring 27, so that the rubber plug 24 is inserted into the through hole 22, thereby automatically blocking the through hole 22, thus avoiding the waste of water resources and saving manpower and time.

[0037] In the present invention, the "fixed connection" described means that the two components connected to each other are fixed together, generally by means of welding, screws or adhesives; the "rotating connection" means that the two components are connected together and can move relative to each other.
