The various embodiments of this utility model are described in detail below with reference to the accompanying drawings.
[0017] Example 1
[0018] Please see Figures 1 to 7The present invention preferably provides the following technical solution: a quick-release lip-adjustable casting die head, including an extruder port 312 and elongated wedge grooves 314 respectively opened on both sides of the extruder port 312; the casting die head further includes: a casting module; a quick-release module disposed on the casting module and assembled with the extruder port 312; wherein, the casting module includes a first casting module 111, a second casting module 112 and an elastic lip 113 forming the casting cavity from top to bottom; transmission pressure plate assemblies respectively disposed on opposite sides of the two second casting modules 112; each transmission pressure plate assembly includes a lifting transmission frame, a plurality of screw transmission units disposed on the lifting transmission frame; and a wedge block transmission assembly connected to the bottom end of each screw transmission unit. When the lifting transmission frame is running as a whole, the plurality of wedge block transmission assemblies on both sides move closer and further apart to achieve overall adjustment of the gap between the two elastic lips 113; when a local screw transmission unit is adjusted, the wedge block transmission assembly at the corresponding position performs local adjustment of the gap to meet different extrusion processes.
[0019] In this embodiment, the quick-release module and the casting module are arranged on the top and bottom, combined with... Figure 1 , 2 As shown in Figure 4, the quick-release module can be detachably assembled with the extruder and realize quick-release and quick-uninstallation operation between it and the extruder port 312. The casting module includes, from top to bottom, a first casting module 111, a second casting module 112, and an elastic lip 113 forming the casting cavity. Figure 3 , 5 As shown, there are two sets of transmission pressure plate assemblies. Each set of transmission pressure plate assemblies consists of a lifting transmission frame, several screw transmission units, and a wedge block transmission assembly connected to the bottom of each screw transmission unit. The two sets of wedge block transmission assemblies are respectively assembled on opposite sides of two elastic lips 113. When the lifting transmission frame is running, the two sets of wedge block transmission assemblies can be moved closer or further away from each other. This process can make the two elastic lips 113 move closer or further away from each other, thereby realizing the adjustment of the gap and satisfying the adjustment of the thickness of the extruded material. This design is suitable for quickly matching the basic thickness when changing materials or setting the initial thickness by synchronously changing the entire lip gap, while maintaining macroscopic uniformity. When adjusting the local screw drive unit, combined with Figure 3 As shown, the wedge drive assembly at the corresponding position can perform local adjustment of the gap, thereby satisfying the local gap adjustment of the two elastic lips 113. This design not only meets different extrusion processes, but also can accurately compensate for defects and specifically correct local deviations. By integrating the two adjustment methods of overall and local, this device can achieve the process of first adjusting the overall thickness to close to the target thickness, and then using local adjustment to optimize the remaining deviation, thereby improving extrusion accuracy. The method of adjusting locally first and then overall can significantly improve extrusion efficiency.
[0020] Furthermore, the bottom opening of the first casting module 111 is also provided with several flow-diverting grooves 116, combined with... Figure 7 As shown, this design can improve the uniformity of the film flowing into the first casting module 111.
[0021] Example 2
[0022] As another embodiment of the present invention, each set of wedge block transmission components includes a rectangular wedge groove 114 opened on the outside of the elastic lip 113, and a wedge block body 115 is provided in the rectangular wedge groove 114. Furthermore, each set of lifting transmission frames includes vertical plates 211 fixed on both sides of the second casting module 112, and an inclined plate 212 fixed between the two vertical plates 211; and a plurality of transmission grooves 213 opened on the side of the inclined plate 212 near the elastic lip 113, and a transmission block 214 is provided in each transmission groove 213, and the transmission block 214 is fixed to the side wall of its corresponding wedge block body 115; each set of lifting transmission frames also includes a drive mechanism for overall adjustment of the plurality of transmission blocks 214; further, the drive mechanism includes sliding grooves 215 opened on the opposite sides of the two vertical plates 211, a slider 216 is provided in each sliding groove 215, and a transmission bar 217 is fixed between the two sliders 216, wherein a plurality of screw transmission units are assembled on the transmission bar 217; and a mounting plate 219 fixed to the top of each vertical plate 211, wherein an electric telescopic rod 220 is mounted on the mounting plate 219, wherein the electric telescopic rod 220 is fixed to the transmission bar 217; Furthermore, each screw drive unit includes a screw hole opened on the drive bar 217, and a screw body 218 is provided in the screw hole. A nut is fixed at one end of the screw body 218, and a drive ring is rotatably installed at the other end, and the drive ring is connected to its corresponding drive block 214.
[0023] Each elastic lip 113 has a corresponding rectangular wedge groove 114 and transmission groove 213 between it and the inclined plate 212 on the same side. The wedge block body 115 in the rectangular wedge groove 114 and the transmission block 214 in the transmission groove 213 are fixed to each other. At the same time, the transmission bar 217, which is longitudinally slidably installed between the two vertical plates 211, has several screw transmission units and several transmission blocks 214 mounted on it, which are rotatably installed. Therefore, when the electric telescopic rod 220 where the lifting transmission frame is located extends or retracts, it can realize the lifting and lowering operation of several screw transmission units and several transmission blocks 214 by raising and lowering the transmission bar 217, thereby realizing the overall adjustment of the gap between the two elastic lips 113. Specifically, in combination Figure 3When the two electric telescopic rods 220 extend, they push the two sets of transmission blocks 214 downward and closer to each other. At the same time, they simultaneously push the two wedge bodies 115 closer to each other, thereby reducing the gap between the two elastic lips 113. Conversely, the gap between the two elastic lips 113 widens. When the screw body 218 is turned, the local transmission block 214 can be raised or lowered, thereby adjusting the gap between the two elastic lips 113 locally.
[0024] Example 3
[0025] As another embodiment of this utility model, the quick-release module includes an assembly frame 311 fixed in the middle of the first casting module 111 and communicating with the first casting module 111, wherein the assembly frame 311 is connected to the extruder port 312; and a bolt drive assembly disposed on the assembly frame 311 for quick-release and quick-installation of the assembly frame 311 and the extruder port 312; further, the bolt drive assembly includes screw holes respectively opened on both sides of the assembly frame 311, each screw hole being provided with a bolt body 313; and wedges 315 respectively rotatably installed at opposite ends of the two bolt bodies 313, and the two wedges 315 being drively connected to two elongated wedge grooves 314.
[0026] It is known that one end of the assembly frame 311 is connected to the top of the first casting module 111, and the other end is assembled with the extruder port 312. Simultaneously, a bolt body 313 is provided on the side wall of the assembly frame 311, the inner end of which extends into the assembly frame 311 and is rotatably mounted with a wedge strip 315 that matches the elongated wedge groove 314. Figure 3 , 5 As shown, when the extruder port 312 is inserted into the assembly frame 311, rotating the two bolt bodies 313 inward will cause the two wedges 315 to move into the two elongated wedge grooves 314 respectively. Due to the shape characteristics of the elongated wedge grooves 314 and the wedges 315, as the two wedges 315 continue to extend inward, the extruder port 312 will continue to extend into the assembly frame 311, ensuring the stability of the installation. Conversely, the operation will disengage the wedges 315 from the elongated wedge grooves 314.
[0027] Furthermore, the lower part of the assembly frame 311 is also provided with a stepped portion, and a sealing ring 316 is provided inside the stepped portion, in conjunction with... Figure 4 , 5 As shown in Figure 6, the connection sealing between the assembly frame 311 and the extruder port 312 can be improved.

For example, it can be a fixed connection, a detachable connection, or an integral part. There are various ways to install detachably, such as by using a plug-in and snap-fit method, or by using a bolt connection, etc.
