DETAILED DESCRIPTION

[0020] The preferred embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0021] As Figures 1-4As shown, a tape mold flow-blocking rod sealing device includes an upper mold 1, which is positioned above a lower mold 2. Both the upper mold 1 and the lower mold 2 are provided with inlets 3 and outlets 4. A mold head 5 is movably mounted on the bottom surface of the upper mold 1. An installation groove 6 is formed on the bottom surface of the upper mold 1. A flow-blocking rod 7 is movably mounted inside the installation groove 6. Fixing grooves 8 are formed on the left and right sides of the flow-blocking rod 7. Circular sealing strips 9 are fixed inside the two fixing grooves 8. A plurality of rotating grooves 10 are formed on the top surface of the flow-blocking rod 7. A plurality of first threaded holes 11 are formed on the top surface of the upper mold 1. First bolts 12 are threaded into the plurality of first threaded holes 11. Rotating blocks 13 are fixed to the bottom ends of the plurality of first bolts 12. The plurality of rotating blocks 13 are rotatably mounted in the plurality of rotating grooves 10.

[0022] In operation, the operator first installs the upper mold 1 and lower mold 2 onto the extrusion device (not shown in the figure) and closes the molds. The extrusion device then begins operation, conveying molten material through the feed inlet 3 into the cavity between the upper mold 1 and lower mold 2. When the material flows to the bottom of the flow-blocking bar 7, the operator rotates the first bolt 12, causing the rotating block 13 to rotate inside the rotating groove 10. This adjusts the gap between the flow-blocking bar 7 and the lower mold 2, thereby regulating the mold pressure and ensuring more uniform material output. Simultaneously, the circular sealing strip 9 seals the material, preventing leakage. The material then exits through the discharge port 4 between the upper mold 1 and lower mold 2 and the die head 5. The combined use of the flow-blocking bar 7, circular sealing strip 9, first bolt 12, and rotating block 13 facilitates mold pressure adjustment, improves material uniformity, prevents leakage, and enhances production efficiency and product quality.

[0023] like Figures 1-4 As shown, the top surface of the upper mold 1 and the bottom surface of the lower mold 2 are respectively provided with connecting grooves 14, and temperature sensors 15 are detachably installed inside the two connecting grooves 14.

[0024] During use, the temperature sensor 15 facilitates real-time monitoring of the internal temperature of the upper mold 1 and the lower mold 2, and feeds the data back to the control system (not shown in the figure), so that the staff can understand the temperature changes.

[0025] like Figures 1-4 As shown, the upper mold 1 is provided with a flow-blocking groove tip 16, and two positioning posts 17 are fixed on the bottom surface of the upper mold 1. Two positioning grooves 18 are opened on the top surface of the lower mold 2, and the two positioning grooves 18 respectively position the two positioning posts 17.

[0026] In use, when the staff installs the flow resistance rod 7 in the installation groove 6, the two sides of the circular sealing strip 9 are made of polytetrafluoroethylene, so that when the circular sealing strip 9 enters the installation groove 6 through the flow resistance groove tip 16, the excess part can be directly cut off, ensuring that the cut circular sealing strip 9 can tightly adhere to the inner wall of the installation groove 6 to form effective sealing, not only preventing the occurrence of glue leakage, but also improving the stability and durability of the flow resistance rod 7. Through the cooperation of the positioning column 17 and the positioning groove 18, it is beneficial to assist in positioning when the upper mold 1 and the lower mold 2 are closed, not only ensuring the accurate alignment between the upper mold 1 and the lower mold 2, but also preventing the deviation during the closing process.

[0027] As shown in Figures 1-4 The top surface of the die head 5 is provided with a plurality of movable holes 19, the top surface of the upper mold 1 is provided with a plurality of second threaded holes 20, a plurality of second threaded holes 20 are respectively threadedly connected with second bolts 21, the bottom ends of a plurality of second bolts 21 are respectively fixed with movable blocks 22, a plurality of movable blocks 22 are respectively rotatably arranged in a plurality of movable holes 19, the top surface of the upper mold 1 and the bottom surface of the lower mold 2 are respectively provided with two threaded grooves 23, the outer walls of the two temperature sensors 15 are respectively fixed with mounting frames 24, the top surfaces of the two mounting frames 24 are respectively provided with two third threaded holes 25, and the two third threaded holes 25 are respectively threadedly connected with third bolts 26. The threaded ends of the two third bolts 26 are respectively threadedly connected with the interiors of the two threaded grooves 23.

[0028] In use, the staff rotates the second bolt 21 to rotate the movable block 22 in the interior of the movable hole 19, thereby pushing the die head 5 to adjust up and down, so that the thickness of the discharged material can be adjusted according to different production needs. Through the cooperation of the mounting frame 24 and the third bolt 26, the staff can disassemble and assemble the temperature sensor 15, thereby facilitating the maintenance or replacement of the temperature sensor 15.

[0029] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
