Description

Technical Field

[0001] This utility model relates to the technical field of mold separation devices, specifically an aluminum profile extrusion mold separation device. Background Technology

[0002] Aluminum alloy extrusion dies are composite dies composed of upper and lower molds. After extrusion production or trial molding, a certain amount of scrap aluminum remains in the die holes, preventing the upper and lower molds from separating. To separate the molds, a "cooking" process is required, where the mold is placed in an alkaline tank containing sodium hydroxide solution to remove the scrap aluminum clogging the die holes. Then, the molds are manually separated by tapping the gap between the upper and lower molds using homemade wedges and hammers. This separation method has the following problems: 1. After the cooking process, sodium hydroxide solution remains in the mold. During subsequent manual tapping, liquid splashes often occur. If the highly alkaline sodium hydroxide solution splashes into the eyes or arms, it can cause harm to human health. 2. The manual tapping process relies on the hands to hold the hammer and wedges, which can easily injure the hands, posing a safety hazard to the mold operator. 3. Uneven force distribution during manual tapping can damage the mold's interlocking seams, affecting the mold's lifespan. Utility Model Content

[0003] The main purpose of this utility model is to provide an aluminum profile extrusion die separation device to solve the problem that the separation of the upper and lower dies in the aluminum alloy extrusion die can easily cause injury to people and the die in the prior art.

[0004] To achieve the above objectives, this utility model provides an aluminum profile extrusion die separation device, including a portal frame. A slide rail is provided on the inner side of the portal frame along the front-to-back direction. A die moving trolley is slidably connected on the slide rail. A first hydraulic cylinder is connected to the front side of the die moving trolley to drive the moving trolley to move. Second hydraulic cylinders are fixedly connected to the left and right sides of the portal frame. The piston rods of the second hydraulic cylinders on the left and right sides are arranged opposite to each other and fixedly connected to a die-opening cutter for die separation. The head of the die-opening cutter is wedge-shaped.

[0005] Furthermore, a hydraulic station is fixedly connected to the top of the portal frame. The hydraulic station includes an oil tank, a hydraulic pump connected to the oil tank via a pipeline, a hydraulic valve connected to the hydraulic pump via a pipeline, and a first hydraulic cylinder and a second hydraulic cylinder connected to the hydraulic valve via a pipeline. The hydraulic valve and the hydraulic pump are electrically connected to a control box.

[0006] Furthermore, the top of the mobile trolley is provided with two opposing first rollers and two opposing second rollers; the second rollers are located outside the first rollers and are positioned higher than the first rollers.

[0007] This invention, by setting up a first hydraulic cylinder, a second hydraulic cylinder, and a mold-opening cutter, replaces humans in separating the assembled molds, avoiding corrosive liquids from hitting people and preventing injuries to workers when striking the molds; furthermore, by controlling the action of the mold-opening cutter through the hydraulic cylinders, the advancing speed and direction of the mold-opening cutter can be precisely controlled, making the force on the mold gap joint more balanced and preventing damage to the mold.

[0008] This invention, by setting a first roller and a second roller, can accommodate molds of more sizes; when the mold size is small, the mold abuts against the first roller; when the mold size is large, the mold abuts against the second roller. Attached Figure Description

[0014] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0015] like Figures 1 to 3As shown, according to an embodiment of the present invention, an aluminum profile extrusion die separation device is provided, including a portal frame 1. A slide rail 2 is provided on the inner side of the portal frame 1 along the front-rear direction. A die moving trolley 3 is slidably connected to the slide rail 2. A slider that cooperates with the slide rail 2 is fixedly connected to the bottom of the die moving trolley 3. A first hydraulic cylinder 4 that drives the moving trolley 3 to move is connected to the front side of the die moving trolley 3. Second hydraulic cylinders 5 are fixedly connected to both the left and right sides of the portal frame 1. The piston rods of the second hydraulic cylinders 5 on the left and right sides are arranged opposite to each other and are fixedly connected to a die-opening knife 6 for die separation through a knife holder. The head of the die-opening knife 6 is wedge-shaped.

[0016] A hydraulic station is fixedly connected to the top of the portal frame 1. The hydraulic station includes an oil tank 7. The oil tank 7 is connected to a hydraulic pump 8 through a pipe. The hydraulic pump 8 is connected to a hydraulic valve 9 through a pipe. The hydraulic valve 9 is connected to a first hydraulic cylinder 4 and a second hydraulic cylinder 5 through a pipe. The hydraulic valve 9 and the hydraulic pump 8 are electrically connected to a control box 10.

[0017] The top of the mobile trolley 3 is provided with two opposing first rollers 301 and two opposing second rollers 302; the second rollers 302 are located outside the first rollers 301 and are positioned higher than the first rollers 301; the extrusion die is cylindrical in shape, and the first rollers 301 and the second rollers 302 are used to support the extrusion die; by providing the first rollers and the second rollers, more sizes of dies can be accommodated; when the die size is small, the die abuts against the first roller; when the die size is large, the die abuts against the second roller.

[0018] The operating method of the aluminum profile extrusion die separation device is as follows:

[0019] First, the first hydraulic cylinder 4 pushes the moving trolley 3 to the rear of the portal frame 1, and the overhead crane hoists the extrusion mold and places it on the moving trolley 3;

[0020] The first hydraulic cylinder 4 pulls the moving trolley 3 back into the portal frame 1, so that the gap between the upper and lower dies of the extrusion mold is aligned with the blade of the die-opening knife 6.

[0021] The second hydraulic cylinder 5 pushes the mold-opening knife 6 into the gap between the upper and lower molds of the extrusion mold, thus separating the upper and lower molds.

[0022] The aluminum profile extrusion die separation device uses a first hydraulic cylinder, a second hydraulic cylinder, and a die-opening blade to separate the assembled die instead of a person. This avoids corrosive liquids from hitting people and prevents them from being injured by hitting their hands when striking the die, thus avoiding injury to workers. Furthermore, by controlling the action of the die-opening blade through the hydraulic cylinder, the device can precisely control the speed and direction of the die-opening blade's advance, making the force on the die's clamping joint more even and preventing damage to the die.

[0023] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
