Description

Technical Field

[0001] This utility model relates to the field of guiding device technology, specifically a guiding device for injection molds. Background Technology

[0002] Injection molds are tools used to produce plastic products. Through injection molding, plastic material is injected into the mold cavity, and after cooling and solidification, the desired plastic product is obtained. Injection molds typically consist of a moving mold and a fixed mold. The cavity is located on the mating surface of these two mold parts. When the mold closes, molten plastic is injected into the cavity, where it cools and hardens. The mold is then opened to remove the product. The guiding device, as a key component of injection molds, is mainly used to ensure precise positioning of the mold during the mold-closing process and to withstand the enormous pressure during mold closing, preventing mold misalignment or damage. The guiding device typically consists of guide pillars and guide sleeves, which work together to guide the accurate opening and closing of the mold. However, the replacement of guide pillars and guide sleeves in existing injection mold guiding devices is not convenient. Guide pillars and guide sleeves are usually firmly installed inside the mold. When the guiding device wears or is damaged, replacing the guide pillars and guide sleeves often requires disassembling the entire mold, making the replacement process quite complex and time-consuming.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1 to 6 This utility model provides a technical solution: a guiding device for injection molds, comprising: a moving mold 1; a stationary mold 2 placed on one side of the moving mold 1; a first mounting hole 4 symmetrically opened inside the stationary mold 2, and a guide sleeve 6 installed inside the first mounting hole 4; a second mounting hole 22 symmetrically opened inside the moving mold 1; a side fixing frame 8 symmetrically fixed to one side of the moving mold 1, and a limit mounting opening 21 opened inside the side fixing frame 8; a guide post 3 installed inside the second mounting hole 22, the guide post 3 cooperating with the guide sleeve 6, and a fixing rod 1 fixedly connected to one end of the guide post 3. 6; The sliding sleeve 17 is slidably disposed on the outside of the fixed rod 16, and one end of the sliding sleeve 17 is fixedly connected to a fixed side block 19 that cooperates with the limiting installation port 21; the limiting plate 23 is slidably disposed inside the sliding sleeve 17, and the end of the fixed rod 16 away from the guide post 3 is fixedly connected to the limiting plate 23; the second spring 18 is disposed inside the sliding sleeve 17, one end of the second spring 18 is fixedly connected to the sliding sleeve 17, and the other end of the second spring 18 is fixedly connected to the limiting plate 23; the limiting slot 20 is symmetrically opened on one side of the fixed side block 19; the mounting part is placed inside the side fixing frame 8.

[0031] It is understood that when the guide post 3 is installed, the guide post 3, the fixing rod 16, the sliding sleeve 17 and the second mounting hole 22 cooperate. When the fixing side block 19 enters the limiting mounting port 21, the fixing side block 19 will push the inclined surface 11 on one side of the limiting block 10. The inclined surface 11 is forced to move the limiting block 10 and the limiting slide plate 9. The limiting slide plate 9 presses the first spring 13. When the fixing side block 19 is completely inside the limiting mounting port 21, the first spring 13 will reset and drive the limiting slide plate 9 and the limiting block 10 to reset. The limiting block 10 enters the limiting slot 20 on one side of the fixing side block 19, limiting the fixing side block 19 inside the limiting mounting port 21. Then, by rotating the mounting bolt 14, the mounting bolt 14 is threaded into the threaded groove 15, further stabilizing the position of the fixing side block 19 in the limiting mounting port 21. The guide sleeve 6 then enters the first mounting hole 22. The guide sleeve 6 is installed within the hole 4. The mounting side plate 7 at one end of the guide sleeve 6 enters the inner side of the mounting groove 5. The mounting side plate 7 is stably installed in the mounting groove 5 by bolts, thus fixing the position of the guide sleeve 6. The guide is guided by the cooperation between the guide post 3 and the guide sleeve 6. When the guide sleeve 6 needs to be disassembled and replaced, simply remove the bolt connecting the mounting side plate 7 and the mounting groove 5 to remove the guide sleeve 6 and the mounting side plate 7, thus completing the replacement of the guide sleeve 6 and the mounting side plate 7. When the guide post 3 needs to be replaced, the mounting bolt 14 is rotated outward, and the mounting bolt 14 is disengaged from the threaded installation between the mounting bolt 14 and the threaded groove 15. At this time, the pull rod 12 can be pulled. When the pull rod 12 is pulled, it drives the limit slide plate 9, the limit block 10, and the inclined surface 11 to move. The limit block 10 is disengaged from the limit installation between the limit block 20. At this time, the fixed side block 19 can be pulled out to disassemble and maintain the guide post 3.

[0032] Please see Figures 1 to 4 The installation part includes a limiting slide plate 9, which is slidably disposed inside the side fixing frame 8. A limiting block 10 that cooperates with the limiting slot 20 is symmetrically fixed to one side of the limiting slide plate 9. A slope 11 that cooperates with the fixed side block 19 is provided on one side of the limiting block 10.

[0033] It is understood that the limiting block 10 of this utility model enters the limiting slot 20 on one side of the fixed side block 19. The limiting block 10 restricts the installation position of the fixed side block 19 in the limiting installation port 21 through the limiting slot 20, and restricts the installation position of the fixed side block 19, the sliding sleeve 17, the fixing rod 16 and the guide post 3.

[0034] Please see Figures 1 to 4A pull rod 12 is fixedly connected to one side of the limiting slide plate 9. The pull rod 12 is slidably connected to the side fixing frame 8. A first spring 13 is symmetrically arranged inside the side fixing frame 8. One end of the first spring 13 is fixedly connected to the limiting slide plate 9, and the other end of the first spring 13 is fixedly connected to the side fixing frame 8.

[0035] It is understood that this utility model uses the pull rod 12 to pull the limiting slide plate 9 and the limiting block 10, thereby disassembling the limiting block 10 and the limiting slot 20, which facilitates the disassembly of the fixed side block 19, the sliding sleeve 17, the fixed rod 16 and the guide post 3.

[0036] Please see Figures 1 to 4 The side fixing frame 8 is internally connected with a mounting bolt 14, and a threaded groove 15 that mates with the mounting bolt 14 is provided on one side of the fixing side block 19.

[0037] It is understood that the mounting bolt 14 of this utility model is threadedly connected to the threaded groove 15 to stabilize the mounting position of the fixed side block 19 inside the limiting mounting port 21.

[0038] Please see Figures 1 to 6 The static mold 2 has symmetrically opened mounting grooves 5 on one side, which are connected to the first mounting hole 4. One end of the guide sleeve 6 is fixedly connected to a mounting side plate 7 that cooperates with the mounting groove 5. The mounting side plate 7 and the mounting groove 5 are connected by bolts.

[0039] It is understood that the guide sleeve 6 of this utility model is installed in the first mounting hole 4, and the mounting side plate 7 is installed in the mounting groove 5 for limiting installation. The mounting side plate 7 and the mounting groove 5 are installed and fixed by bolts to complete the fixed installation of the guide sleeve 6.

[0040] Please see Figure 1 A handle 24 is fixedly attached to one side of the fixed side block 19.

[0041] It is understandable that the present invention allows for easy disassembly and extraction of the fixed side block 19 via the handle 24.
