Description

Technical Field

[0001] The utility model belongs to the technical field of aluminum profile demoulding, in particular to an aluminum profile mold which is convenient for demoulding. Background Art

[0002] At present, industrial aluminum profiles are stamped in molds. Stamping is a special process equipment that processes materials into parts. The discharge process is to place the workpiece into the extrusion molding die. The stamping process is to close the upper and lower molds to stamp the workpiece. The discharge process is to take the extruded workpiece out of the mold.

[0003] After searching, the Chinese utility model patent with announcement number CN218109076U discloses an aluminum profile forming mold that is easy to demold. Although the above device places the aluminum material on the die, and then the punch at the front end of the cylinder extends into the die to stamp the aluminum material, and then the cylinder retracts, the formed product will be stuck on the outside of the punch, and then the second spring will reset to push the ejector plate back to the top, and the ejector plate will push the product away from the punch, thereby realizing automatic demolding. When the demolded product is still in the inner cavity of the die, when taking it out, use your hand to reach into the die. If the product is in close contact with the inner wall of the die, when taking it out from the inner cavity of the die, the product may generate friction with the inner cavity of the die, resulting in jamming during removal, making it inconvenient to quickly take it out from the inner cavity of the die.

[0004] To this end, we propose an aluminum profile mold that is easy to demould to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problem in the prior art that it is inconvenient to quickly take out the aluminum profile, and to propose an aluminum profile mold that is easy to demould.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The top of described supporting plate is fixedly provided with the support column of the outer shell of the concave mold, and the top of described supporting plate is fixedly provided with the support column of the outer shell of the concave mold.

[0008] Preferably, the pressing assembly includes two pressing plates, one pressing plate close to the connecting plate is slidably sleeved on the connecting rod, and the other pressing plate away from the connecting plate is fixedly connected to the connection, and a spring sleeved outside the connecting rod is fixedly connected between the two pressing plates.

[0009] Preferably, the top surface of a pressing plate away from the connecting plate is flush with the top surface of the punch.

[0010] Preferably, the lifting member includes a lifting plate fixedly connected to the bottom end of the connecting rod, and a rectangular groove for the lifting plate to move is provided on the bottom plate.

[0011] Preferably, a vertical guide rod is fixedly connected in each of the movable grooves, and a guide hole adapted to the guide rod is provided on each side of the connecting plate.

[0012] Preferably, three sides of the top surface of the die are fixedly connected to limit bars.

[0013] Preferably, the distance between the top surface of the connecting plate and the inner top wall of the movable groove is greater than the distance between the top surface of the top plate and the top surface of the die.

[0014] In summary, the technical effects and advantages of the utility model are as follows: by arranging the top plate, the connecting plate, the connecting rod, the fixed plate, the cylinder, the fixed column and the lifting piece, the aluminum profile is placed on the top surface of the die, the punch is pushed down by the cylinder, and the fixed plates on both sides of the fixed column are lowered together with the connecting rods when the punch is lowered. After the aluminum profile is punched by the punch, it falls into the inner cavity of the die. When the cylinder lifts the die, the connecting rods on both sides of the fixed plate move up, and the lifting piece at the bottom of the connecting rod lifts the connecting plate when it moves up, and at the same time lifts out the top plate in the die and lifts out the product that falls into the die, thereby realizing demoulding of the product in the die and lifting the product out of the inner cavity of the die, making it easier to take out the material.

[0015] Through the setting of the downward pressing component, when the top plate is lifted, another aluminum profile is placed on the top surface of the die again, and then the punch is lowered again with the push of the cylinder. At the same time, the downward pressing component on the top of the connecting plate presses down the lifted connecting plate, and the connecting plate is slowly pressed down and reset as the cylinder moves, thus realizing the downward reset of the lifted top plate without hindering the stamping of the next product.

[0021] 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.

[0022] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] Reference Figure 1-Figure 2, an aluminum profile mold that is easy to demould, includes a bottom plate 1, a die 8 is fixedly installed at the center of the top surface of the bottom plate 1, and movable grooves 16 are opened on both sides of the die 8, and the movable grooves 16 are located in the middle of the die 8 on both sides. The four corners of the bottom plate 1 are fixedly connected to the support columns 2 located on the outside of the die 8, and the top surfaces of the four support columns 2 are fixedly connected to the mounting plate 3. The cylinder 4 is fixedly installed on the mounting plate 3, and the movable end of the cylinder 4 is fixedly connected to the fixed column 6. The bottom surface of the fixed column 6 is fixedly connected to the punch 7 above the die 8, and the circumferential surface of the fixed column 6 is fixedly connected to the fixed plate 5 above the die 8. A top plate 15 is provided in the inner cavity of the die 8, and the top plate 15 is slidably embedded in the inner cavity of the die 8. Both sides of the top plate 15 are fixedly connected with connecting plates 12 that pass through the movable groove 16 and extend out of the die 8. Each fixed plate 5 is away from the fixed column One end of 6 is fixedly connected with a connecting rod 9, and each connecting rod 9 above the connecting plate 12 is provided with a pressing component for pressing the connecting plate 12 downward, and the connecting rod 9 below the connecting plate 12 is provided with a lifting piece for lifting the connecting plate 12. By placing the aluminum profile on the top surface of the die 8, the cylinder 4 pushes the punch 7 to descend, and when the punch 7 descends, the fixed plates 5 on both sides of the fixed column 6 are lowered together with the connecting rod 9. When the aluminum profile is stamped by the punch 7, it falls into the inner cavity of the die 8. When the cylinder 4 lifts the punch 7, the connecting rods 9 on both sides of the fixed plate 5 move up, and the lifting piece at the bottom of the connecting rod 9 will lift the connecting plate 12 when moving up, and at the same time lift out the top plate 15 in the die 8, and lift up the product that falls into the die 8 together, thereby realizing demoulding of the product in the die 8 and lifting the product out of the inner cavity of the die 8, making it easier to take out the material.

[0024] Reference Figure 2-Figure 3 The pressing assembly includes two pressing plates 10. A pressing plate 10 close to the connecting plate 12 is slidably sleeved on the connecting rod 9, and the other pressing plate 10 away from the connecting plate 12 is fixedly connected to the connection. A spring 11 sleeved on the outside of the connecting rod 9 is fixedly connected between the two pressing plates 10. When the cylinder 4 descends, it pushes the punch 7 closer to the die 8. At the same time, the fixed plates 5 on both sides of the punch 7 will move down synchronously. At this time, the connecting plate 12 outside the die 8 will be contacted by the pressing plate 10 below, and the connecting plate 12 will be pressed down, and the spring 11 will be squeezed at the same time. As the punch 7 gradually descends, the pressing plate 10 and the spring 11 in contact with the connecting plate 12 will press and fix the connecting plate 12, and at the same time, the top plate 15 in the die 8 will be reset.

[0025] Reference Figure 2 The top surface of a pressing plate 10 away from the connecting plate 12 is flush with the top surface of the punch 7. As the punch 7 descends, the top plate 15 is first pushed to the bottom surface of the die 8, leaving enough space between the top surface of the top plate 15 and the top surface of the die 8 for the product to fall.

[0026] Reference Figure 3The lifting member includes a lifting plate 13 fixedly connected to the bottom end of the connecting rod 9, and a rectangular groove 14 for the lifting plate 13 to move is opened on the bottom plate 1. When the connecting rod 9 descends, the lifting plate 13 at the bottom of the connecting rod 9 will pass through the rectangular groove 14 opened on the bottom plate 1. When the connecting rod 9 rises, the lifting plate 13 will lift the connecting plates 12 on both sides of the top plate 15 as it moves, and at the same time lift the top plate 15, and then lift the product embedded in the inner cavity of the die 8 out of the top plate 15, which is convenient for demoulding and material removal.

[0027] Reference Figure 4 A vertical guide rod 17 is fixedly connected to each movable groove 16, and a guide hole adapted to the guide rod 17 is opened on each side connecting plate 12. When the connecting plate 12 moves up along the guide rod 17, the top plate 15 is prevented from being stuck in the inner cavity of the die 8 when the connecting plate 12 moves up, and at the same time, it guides the movement of the connecting plate 12.

[0028] Reference Figure 4 The three sides of the top surface of the die 8 are fixedly connected to the limiting strips 18, and the aluminum profile can be placed in the gap between the three-side limiting strips 18 to ensure the stability of the placement after being pushed from one side to the other.

[0029] Reference Figure 2 The distance between the top surface of the connecting plate 12 and the inner top wall of the movable groove 16 is greater than the distance between the top surface of the top plate 15 and the top surface of the die 8. When the connecting plate 12 moves, the bottom plate 1 completely lifts the product in the die 8 out of the inner cavity of the die 8 for easy collection.

[0030] Working principle:

[0031] The aluminum profile is pushed from one side of the die 8 to the other side and placed in the gap between the limit bars 18 on the three sides of the die 8. The cylinder 4 then pushes the punch 7 down. As the punch 7 descends, the fixed plates 5 on both sides of the fixed column 6 descend together with the connecting rod 9. After the aluminum profile is punched by the punch 7, it falls into the inner cavity of the die 8. When the cylinder 4 lifts the punch 7, the connecting rods 9 on both sides of the fixed plate 5 move up. At the same time, the lifting parts at the bottom of the connecting rod 9 lift the connecting plate 12 when moving up, and at the same time lift out the top plate 15 in the die 8, and lift up the products that fall into the die 8 together, thereby realizing demoulding of the products in the die 8 and lifting the products out of the inner cavity of the die 8, making it easier to take out the materials.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
