Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of extrusion dies, in particular to an extrusion die for PP hollow templates. Background Technique
[0002] The PP extrusion die is a key component in the extrusion process and is used to shape the molten PP material into the required shape. It is usually installed on an extruder to shape the extruded molten plastic into the required products, such as pipes, sheets, films, plates, etc. The design of the die determines the shape, size, and quality of the product. The PP extrusion die usually has a uniform runner design to ensure the smooth flow of the molten plastic and avoid dead ends and uneven flow. At the same time, a cooling system may be provided inside the die to maintain an appropriate temperature and ensure the stability of the plastic during the shaping process.
[0003] The PP extrusion die is mainly used to extrude molten polypropylene plastic into various shaped products, such as pipes, sheets, films, plates, etc. The traditional PP extrusion die is usually installed at the discharge end of the extruder. By extruding the molten PP material into the runner of the die, it is shaped into the required shape of the product. Since the PP extrusion die is relatively heavy, an auxiliary base is generally provided at its bottom during installation, and then the PP extrusion die is positioned through multiple bolt holes and bolts. However, in the subsequent maintenance process of the PP extrusion die, the staff still needs to disassemble the bolts one by one, which not only consumes manpower but also causes wear to the PP extrusion die due to repeated disassembly.
[0004] Therefore, in view of the above problems, we need to propose an extrusion die for PP hollow templates. Content of the Utility Model

[0026] A locking component 5 disposed in the inner cavity of the connection shell 3 for the staff to quickly disassemble and assemble the extrusion die head.
[0027] The locking component 5 includes a movable disk 501. The movable disk 501 is slidably connected to the surface of the connection shell 3, and its function is to remove the clamping plate 505 from the card slot 2 through the adjusting rod 502 to achieve the effect of quick disassembly. The inner cavity of the movable disk 501 is movably connected to the surface of the connection shell 3. One side of the movable disk 501 is movably connected to an adjusting rod 502 through a rotating shaft. The adjusting rod 502 is located on one side of the movable disk 501, and its function is to adjust the position of the clamping plate 505 through the connecting sleeve 503. One side of the adjusting rod 502 is movably connected to a connecting sleeve 503 through a rotating shaft.
[0028] The inner cavity of the connecting sleeve 503 is fixedly connected with a movable rod 504, and the movable rod 504 is located in the inner cavity of the connecting sleeve 503, and its function is to adjust the position of the clamping plate 505. One side of the movable rod 504 penetrates into the inner cavity of the connecting shell 3 and is fixedly connected with the clamping plate 505. The clamping plate 505 is located in the inner cavity of the connecting shell 3, and its function is to lock and position the connecting shell 3 with the extrusion die head. One side of the clamping plate 505 is clamped with the inner cavity of the card slot 2. A spring 506 is arranged on the surface of the clamping plate 505, and the spring 506 is located on one side of the clamping plate 505, and its function is to reset the clamping plate 505. The side of the spring 506 away from the clamping plate 505 is fixedly connected to the inner wall of the connecting shell 3.
[0029] The inner cavity of the card plate 505 is movably connected with a slide bar 507 . The slide bar 507 is located in the inner cavity of the card plate 505 and functions to limit the card plate 505 . Both ends of the slide bar 507 are fixedly connected to the inner wall of the connecting shell 3 .
[0030] The surface of the connecting shell 3 is provided with a slide bar 6 . The slide bar 6 is located on the surface of the connecting shell 3 . There are several slide bars 6 . The slide bars 6 are used to limit the movable disk 501 . The surface of the slide bar 6 is movably connected to the inner cavity of the movable disk 501 .
[0031] A limiting block 10 is disposed on the surface of the connecting shell 3. The limiting block 10 is located on the surface of the connecting shell 3 and functions to limit the movable disk 501. The limiting block 10 is arranged in a rectangular shape.
[0032] Working principle: When the staff needs to install the extrusion die head, firstly, the connection shell 3 is close to the connection head 1, and then the connection shell 3 is sleeved on the surface of the connection head 1. As the staff continuously inserts the connection shell 3 into the surface of the connection head 1, the inclined surface of the card plate 505 will first contact the connection head 1. One side of the connection head 1 is set to be smooth, so when the inclined surface of the card plate 505 contacts the connection head 1, the card plate 505 will be squeezed into the inside of the connection shell 3, and the spring 506 will shrink. When the connection shell 3 moves to a certain position, the card plate 505 is close to the card slot 2, and the spring 506 will return. The card plate 505 will be snapped into the card slot 2 of the connector 1. At the same time, the flow holes 8 of the first connecting disk 9 and the second connecting disk 7 will also be connected, which is beneficial to the flow of PP material, thereby achieving a quick connection effect. When the subsequent staff dismantles and maintains it, the movable disk 501 is pushed to one side of the connector 1. At this time, the adjusting rod 502 will pull the movable rod 504 upward through the connecting sleeve 503. At this time, the card plate 505 will be moved upward by the movable rod 504 and detached from the inside of the card slot 2. At this time, the staff can remove the connecting shell 3 from the surface of the connector 1 to achieve a quick disassembly effect.
