Abstract
Description
Technical Field
[0001] This utility model belongs to the field of die-making technology, and in particular relates to die-making gaskets. Background Technology
[0002] The die is a key component located at the very end of the extrusion molding equipment. Its main function is to shape the molten material extruded by the extruder into a specified cross-sectional shape and size.
[0003] The existing die is made of mold steel, which needs to be frequently removed and heated at high temperatures to burn off the plastic on top. Over time, it will experience some wear and slight deformation. The lack of a gasket structure to prevent material leakage makes it easy for material to leak when the die is worn and deformed, which is both wasteful of materials and poses a safety hazard.
[0004] Therefore, we propose using a die gasket to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to solve the problem in the prior art that the die is prone to leakage after wear and deformation, which is both wasteful of materials and poses a safety hazard. The proposed die gasket is designed to address this issue.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A die gasket includes a die body. A fixing frame is fixedly connected to both the front and back of the die body. Each fixing frame has five mounting holes on its upper surface. A lower gasket is provided above the die body, and an upper gasket is provided above the lower gasket. The upper surface of the lower gasket has four limiting holes, and the bottom surface of the upper gasket is fixedly connected to four positioning pins.
[0008] Preferably, the bottom surface of the lower pad is in contact with the upper surface of the die body, the front surface of the lower pad and the front surface of the upper pad are both in contact with the back surface of one of the fixing frames, the back surface of the lower pad and the back surface of the upper pad are both in contact with the front surface of the other fixing frame, the upper surface of the lower pad is in contact with the bottom surface of the upper pad, the outer surface of each positioning pin is engaged with the inside of the limiting hole, and two first limiting sliders are fixedly connected to the front surface and the back surface of the lower pad, and the outer surface of each first limiting slider is slidably connected to the inside of the fixing frame.
[0009] Preferably, two second limiting sliders are fixedly connected to both the front and back sides of the upper pad, and the outer surface of each second limiting slider is slidably connected to the interior of the fixing frame.
[0010] Preferably, two threaded rods are provided above the upper gasket, and a lifting plate is fixedly connected to the top of each threaded rod.
[0011] Preferably, the upper surface of the upper gasket has two threaded holes, and the inner wall of each threaded hole is threadedly connected to the outer surface of the threaded rod.
[0012] Preferably, each of the lifting plates has two anti-slip sleeves fixedly connected to its outer surface, and each of the anti-slip sleeves has several identical anti-slip protrusions fixedly connected to its upper and lower surfaces.
[0013] In summary, the technical effects and advantages of this utility model are as follows:
[0014] Through the cooperation of the die body, fixing frame, mounting hole, lower gasket, upper gasket, limiting hole and positioning pin, the mounting hole can be used with external bolts and other fixing structures to fix the fixing frame to the end of the extruder head, thereby fixing the die body. The positioning pin can be engaged with the limiting hole, and the lower and upper gaskets can be stacked on the die body inside the two fixing frames, thereby effectively preventing material leakage from the die body. This avoids the problem that the die is prone to leakage after wear and deformation due to the lack of a gasket structure to prevent material leakage, which wastes materials and poses safety hazards.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0023] Reference Figures 1-6 This embodiment provides a die gasket, which includes a die body 1. A fixing frame 2 is fixedly connected to both the front and back of the die body 1. Each fixing frame 2 has five mounting holes 3 on its upper surface. A lower gasket 4 is positioned above the die body 1, with its bottom surface contacting the upper surface of the die body 1. Two first limiting sliders 8 are fixedly connected to both the front and back of the lower gasket 4. The outer surface of each first limiting slider 8 is slidably connected to the interior of the fixing frame 2. By setting the first limiting sliders 8, the lower gasket 4 can slide left and right along the fixing frame 2, thereby improving the fit of the lower gasket 4 on the die body 1. Two second limiting sliders 9 are fixedly connected to both the front and back of an upper gasket 5. The outer surface of each second limiting slider 9 is slidably connected to the interior of the fixing frame 2. By setting the second limiting sliders 9, the upper gasket 5 can slide up and down along the fixing frame 2, thereby improving the fit and stability of the upper gasket 5 relative to the lower gasket 4.
[0024] An upper gasket 5 is provided above the lower gasket 4. The front of both the lower gasket 4 and the upper gasket 5 are in contact with the back of one of the fixing brackets 2. The back of both the lower gasket 4 and the upper gasket 5 are in contact with the front of the other fixing bracket 2. The upper surface of the lower gasket 4 is in contact with the bottom surface of the upper gasket 5. Two threaded rods 10 are provided above the upper gasket 5. A lifting plate 11 is fixedly connected to the top of each threaded rod 10. By providing the threaded rods 10, they can be connected to other threaded structures. By providing the lifting plate 11, it is convenient to screw and pull the threaded rods 10.
[0025] The upper surface of the lower washer 4 has four limiting holes 6, and the upper surface of the upper washer 5 has two threaded holes 12. The inner wall of each threaded hole 12 is threadedly connected to the outer surface of the threaded rod 10. By setting the threaded holes 12, they can be threadedly connected to the outer surface of the threaded rod 10, thus making it easy to pull the upper washer 5 away from the lower washer 4.
[0026] Four positioning pins 7 are fixedly connected to the bottom surface of the upper pad 5. The outer surface of each positioning pin 7 is engaged with the inside of the limiting hole 6. Two anti-slip sleeves 13 are fixedly connected to the outer surface of each lifting plate 11. Several identical anti-slip protrusions 14 are fixedly connected to the upper surface and the bottom surface of each anti-slip sleeve 13. By setting the anti-slip protrusions 14, the anti-slip effect of the bottom and upper surfaces of the anti-slip sleeves 13 can be increased. By setting the anti-slip sleeves 13 and the anti-slip protrusions 14, the anti-slip properties of the outer surface of the lifting plate 11 and the stability of the hand pull can be increased together.
[0027] The working principle of this utility model is as follows: In use, the lower gasket 4 and the upper gasket 5 are not used initially. The mounting hole 3 is used in conjunction with external bolts and other fixing structures to fix the fixing frame 2 to the end of the extruder head, thereby fixing the die body 1. When the die body 1 undergoes slight deformation after multiple firings, the die body 1 and the fixing frame 2 are removed from the end of the extruder head. The lower gasket 4 is slid between the two fixing frames 2, and then the upper gasket 5 is slid between the two fixing frames 2. The positioning pin 7 is engaged with the limiting hole 6, thereby making the lower gasket 4 and the upper gasket 5 stably stacked on the die body 1 within the two fixing frames 2. This effectively prevents material leakage from the die body 1 and effectively reduces material loss and die replacement time. The design of the entire die gasket effectively solves the problem that the lack of a gasket structure to prevent material leakage leads to easy material leakage after the die is worn and deformed, which wastes materials and poses safety hazards.
