Description

Technical Field

[0001] This utility model relates to the field of casting machine equipment technology, and in particular to a thickness adjustment device for casting machines. Background Technology

[0002] Casting machines are essential equipment for producing various plastic films, and their performance directly affects the quality and yield of the films. In the production process of EVA film, the thickness adjustment mechanism of the casting machine plays a crucial role in controlling the thickness uniformity of the EVA film. Thickness adjustment of the casting machine refers to adjusting the thickness of the raw material output from the mold; In existing cast film production processes, plastic raw materials are first melted into a molten state, and then passed through the die head of a cast film machine to form a cast film. The cast film is then conveyed by the conveyor rollers of the cast film machine. However, because the position between the upper and lower lips of the die is fixed, the gap width between the upper and lower lips is also fixed, making it impossible to adjust the thickness of the cast film; thus, its application range is limited. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a thickness adjustment device for a casting machine to more accurately resolve these issues.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a thickness adjustment device for a casting machine, including an upper mold and a lower mold disposed below and cooperating with the upper mold. The front end of the lower mold is provided with a fixed lip. The front end of the upper mold, located above the fixed lip, is slidably connected to a movable lip via a sliding assembly. The sliding assembly includes a limiting slide rail disposed at the front end of the upper mold and a limiting slider disposed at the rear end of the movable lip and cooperating with the limiting slide rail. The top of the upper mold is provided with a fixing member for fixing the movable lip. Lifting components for lifting the movable lip are provided on both sides of the fixed lip.

[0005] Furthermore, the fixing component includes a fixing plate disposed on the top of the upper mold and a first fixing hole opened on the fixing plate. The rear end of the movable lip is provided with a plurality of second fixing holes that cooperate with the first fixing hole. The first fixing hole is threaded with a screw in the second fixing hole.

[0006] Furthermore, the lifting assembly includes cylinder components disposed on both sides of the fixed lip, and plate bodies disposed on both sides of the movable lip and cooperating with the output ends of the cylinder components.

Detailed Implementation

[0013] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, a clear and complete description will be provided below in conjunction with the technical solutions in the embodiments of this utility model. Obviously, the described embodiments are some, but not all, of the embodiments of this utility model. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0014] Example refer to Figure 1-4A thickness adjustment device for a casting machine includes an upper mold 1 and a lower mold 2 disposed below the upper mold 1 and cooperating with the upper mold 1. The front end of the lower mold 2 is provided with a fixed lip 21. The front end of the upper mold 1, located above the fixed lip 21, is slidably connected to a movable lip 11 via a sliding assembly 3. The sliding assembly 3 includes a limiting slide rail 31 opened at the front end of the upper mold 1 and a limiting slider 32 disposed at the rear end of the movable lip 11 and cooperating with the limiting slide rail 31. The top of the upper mold 1 is provided with a fixing member 4 for fixing the movable lip 11. The two sides of the fixed lip 21 are provided with lifting assemblies 5 for lifting the movable lip 11. The lifting component 5 provides an upward force to the movable lip 11, causing the movable lip 11 and the limiting slider 32 to move upward along the limiting slide rail 31 and increasing the distance between the movable lip 11 and the fixed lip 21. As the distance between the fixed lip 21 and the movable lip 11 increases or decreases, the thickness of the output material will be adjusted synchronously, thereby increasing the applicability of the equipment. In addition, this lifting method is not only easy to operate, but also has a low cost. In this embodiment, the fastener 4 is provided to fix the adjusted movable lip 11, thereby ensuring the stability of the movable lip 11 during use.

[0015] like Figure 4 As shown, the fixing member 4 includes a fixing plate 41 disposed on the top of the upper mold 1 and a first fixing hole 42 opened on the fixing plate 41. The rear end of the movable lip 11 is provided with a plurality of second fixing holes 43 that cooperate with the first fixing hole 42. The first fixing hole 42 is threaded with a screw 44 in the second fixing hole 43. The first fixing hole 42, the second fixing hole 43 and the screw 44 are provided to fix the adjusted movable lip 11 and ensure the stability of the movable lip 11 during use. In this embodiment, the advantage of having several second fixing holes 43 is that it facilitates the worker to fix the movable lip 11 at different heights, thereby ensuring the proper fixing of the movable lip 11.

[0016] like Figure 2 As shown, the lifting assembly 5 includes cylinder components 51 disposed on both sides of the fixed lip 21, and plate bodies 52 disposed on both sides of the movable lip 11 and cooperating with the output end of the cylinder components 51. The arrangement of cylinder 51 and plate 52 can apply an upward or downward force to the movable lip 11, thereby ensuring the adjustment of the distance between the movable lip 11 and the fixed lip 21.

[0017] like Figure 2As shown, a sealing plate 6 is provided between the fixed lip 21 and the movable lip 11, and an elastic body 61 is provided above and below the sealing plate 6. The sealing plate 6 can seal the space between the movable lip 11 and the fixed lip 21, thereby limiting the range of material output. The elastic body 61 provides a basis for the adjustment of the movable lip 11 and ensures the sealing between the movable lip 11 and the fixed lip 21.

[0018] like Figure 1 As shown, both the upper mold 1 and the lower mold 2 are provided with fixing screw holes 7, and screws 44 are threaded into the fixing screw holes 7. The fixing screw hole 7 and screw 44 can complete the fixing of the upper mold 1 and the lower mold 2.

[0019] like Figure 1 and Figure 2 As shown, a raw material injection pipe 8 is provided on one side of the upper mold 1 and the lower mold 2, and a flow channel 81 that cooperates with the raw material injection pipe 8 is opened inside the upper mold 1 and the lower mold 2. The raw material injection pipe 8 is designed to inject the raw material to be used into the flow channel 81 and to extrude it through the gap between the flow channel 81 and the fixed lip 21 and the movable lip 11.

[0020] Working principle: First, the operator injects the raw material into the flow channel 81 through the raw material injection port using a spiral extruder, and then extrudes it through the gap between the movable lip 11 and the fixed lip 21. When the operator needs to adjust the thickness of the output raw material, the operator first removes the screws 44 in the first fixed hole 42 and the second fixed hole 43, then starts the cylinder 51 and applies an upward force to the plate 52 through the output end of the cylinder 51. This causes the movable lip 11 and the limiting slider 32 to move upward along the limiting slide rail 31, increasing the distance between the movable lip 11 and the fixed lip 21. As the distance between the fixed lip 21 and the movable lip 11 increases or decreases, the thickness of the output raw material will be adjusted accordingly. After the position of the movable lip 11 is adjusted, the operator connects the screws 44 to the first fixed hole 42 and the second fixed hole 43 to fix the movable lip 11.

[0021] It should be noted that this utility model only protects the mechanical part, and the functions implemented by the software control part are not within the scope of protection of this utility model.

[0022] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
