[0021] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. Therefore, all other embodiments of this application described herein, and all embodiments obtained by those skilled in the art without creative effort based on the embodiments in this application, should fall within the scope of protection of this application.
[0022] Reference Figures 1-3 A detachable hot runner plate includes a fixed mold base plate 1. A hot runner fixing plate 2 is bolted to the bottom of the fixed mold base plate 1. A placement groove 11 is formed at the bottom of the hot runner fixing plate 2, and a hot runner plate body 3 is placed in the placement groove 11. Multiple support components are bolted to the bottom of the hot runner fixing plate 2. The support components include two sliding grooves 6, which are formed inside the hot runner fixing plate 2. A threaded groove 7 is formed on the hot runner fixing plate 2, and a threaded rod 8 is threadedly connected to the threaded groove 7. The outer side of the threaded rod 8 can rotate. A pressure plate 10 is connected, and two sliding rods 9 are fixed to the upper surface of the pressure plate 10 by bolts. The sliding rods 9 are slidably connected to the sliding groove 6. Through the cooperation of the sliding rods 9 and the sliding groove 6, the pressure plate 10 is guided to prevent the pressure plate 10 from rotating or tilting. The pressure plate 10 contacts the hot runner plate body 3. The operator rotates the threaded rod 8 to move it downward along the threaded groove 7, thereby moving the sliding rod 9 downward along the sliding groove 6 until the pressure plate 10 disengages from the hot runner plate body 3. At this time, the hot runner plate body 3 loses its compression support.
[0023] Specifically, two top blocks 13 are installed on the top of the hot runner fixing plate 2 via a guide connection assembly. Each top block 13 has a wedge-shaped block 12 integrally formed on one side, and the inclined surface of the wedge-shaped block 12 contacts the hot runner plate body 3. The guide connection assembly includes two slots 16, both of which are located on the top of the hot runner fixing plate 2, with the top blocks 13 located inside the slots 16. Two limiting grooves 15 are provided on the top of the hot runner fixing plate 2, and limiting blocks 14 are welded to the upper surfaces of both top blocks 13. 4. The top block 13 is slidably connected to the corresponding limiting groove 15. Through the cooperation of the limiting block 14 and the limiting groove 15, the top block 13 is guided. The groove 16 is connected to the adjacent limiting groove 15. The groove 16 and the limiting groove 15 are connected to the placement groove 11. The operator pushes the top block 13, so that the wedge block 12 squeezes the hot runner plate body 3 along the placement groove 11 through its inclined surface, thereby making it easy for the operator to separate the hot runner plate body 3 from the hot runner fixing plate 2, and making it easy to disassemble and replace the hot runner plate body 3.
[0024] It should be noted that a groove 5 communicating with the placement groove 11 is opened on the hot runner fixing plate 2. A sealing ring 4 is bonded in the groove 5 and the sealing ring 4 is in contact with the hot runner plate body 3. The sealing ring 4 can make the connection between the hot runner plate body 3 and the hot runner fixing plate 2 tighter. A knob is welded to the part of the threaded rod 8 that passes through the pressure plate 10. A rubber pad is bonded to the upper surface of the pressure plate 10. The rubber pad is in contact with the hot runner plate body 3, so that the pressure plate 10 protects the hot runner plate body 3 while squeezing it, reducing the wear caused by the squeezing support.
[0025] Working principle: When it is necessary to disassemble the hot runner plate body 3, the operator rotates the threaded rod 8 to move it downward along the threaded groove 7, thereby causing the slide rod 9 to move downward along the slide groove 6 until the pressure plate 10 disengages from the hot runner plate body 3. At this time, the hot runner plate body 3 loses its compression support. The operator pushes the top block 13, causing the wedge block 12 to press the hot runner plate body 3 downward along the placement groove 11 through its inclined surface. At the same time, the limiting block 14 and the limiting groove 15 guide the top block 13, thereby facilitating the operator to separate the hot runner plate body 3 from the hot runner fixing plate 2, and facilitating the disassembly and replacement of the hot runner plate body 3.
