Description

Technical Field

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

[0002] Injection molds are key industrial equipment used in injection molding processes. Their core function is to inject molten plastic into a closed cavity under high temperature and pressure. After cooling, the mold forms a plastic product that conforms to the shape of the mold cavity. The molten plastic is pushed by the screw of the injection molding machine and injected into the mold cavity through the nozzle. It is filled and held under high pressure, then cooled and solidified. Finally, the product is demolded by the ejection mechanism. Traditional injection mold positioning mechanisms have the lower mold directly fixed to the support base, which does not have the function of positioning and installation. During installation, repeated adjustments are required, which increases the production preparation time. If the deviation is large, the mold needs to be disassembled and reinstalled, requiring the removal of multiple bolts. Utility Model Content

[0026] 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.

[0027] Please see Figures 1 to 5This utility model provides a technical solution: a positioning mechanism for an injection mold, comprising: a support base 3; a support base 25 installed on the top of the support base 3; a sliding support 4 symmetrically slidably disposed inside the support base 3, with a top limiting slide box 5 bolted to the inner side of the sliding support 4, the top limiting slide box 5 being slidably connected to the support base 3; a positioning clamping member 6 symmetrically slidably disposed inside the top limiting slide box 5, with multiple limiting blocks 7 fixedly connected to the inner side of the positioning clamping member 6; limiting slots 8 symmetrically opened on the outer side of the support base 25, the limiting slots 8 cooperating with the limiting blocks 7; a lower mold 1 fixedly connected to the top of the support base 25; an upper mold 2 placed above the lower mold 1; a side fixing plate 17 symmetrically fixedly installed on the outer side of the upper mold 2 by bolts, with a first guide post 18 symmetrically fixedly connected to the bottom of the side fixing plate 17; a side fixing bracket 19 symmetrically fixedly installed on the outer side of the lower mold 1 by bolts, with a first guide sleeve 20 symmetrically fixedly connected inside the side fixing bracket 19 to cooperate with the first guide post 18.

[0028] It should be noted that in this embodiment, the support base 25 and the lower mold 1 are placed on the support base 3. The device is centrally controlled by an external controller. The output end of the second servo motor 13 drives the second bidirectional lead screw 14 to rotate. When the second bidirectional lead screw 14 rotates, it drives the outer symmetrical second slider 15 to move. The second slider 15 drives the sliding support 4 to move. The sliding support 4 slides within the support base 3. The sliding support 4 drives the top limit slide box 5 to slide on the support base 3. The symmetrical top limit slide box 5 restricts the position of the support base 25 and the lower mold 1 on the support base 3. The output end of the first servo motor 11 drives the first bidirectional lead screw 9 to rotate. When the first bidirectional lead screw 9 rotates, it drives the outer symmetrical first slider 10 to slide within the top limit slide box 5. The first slider 10 drives the positioning clamp 6 and the limiting block 7 to move. The movement is achieved by positioning and restricting the position of the support base 25 through the positioning clamping component 6. The limiting block 7 is fixed with each limiting slot 8 to position and fix the support base 25. The position of the lower mold 1 is also positioned. The second guide post 21 at the bottom of the upper mold 2 cooperates with the second guide sleeve 22 symmetrically inside the lower mold 1. The first guide post 18 symmetrically at the bottom of the side fixed support plate 17 cooperates with the first guide sleeve 20 symmetrically inside the side fixed bracket 19 to position the lower mold 1 and the upper mold 2. The output end of the ejector cylinder 26 drives the ejector plate 24 and multiple ejector pins at the top to move, which facilitates the ejection of the molded part in the lower mold 1. Only periodic maintenance of each lead screw, servo motor and cylinder component is required to ensure the positioning effect of the injection mold and greatly shorten the time for mold disassembly and installation positioning.

[0029] In one embodiment, such as Figures 1 to 5As shown, a support base box 12 is fixedly installed at the bottom of the support base 3 by bolts. A second bidirectional lead screw 14 is rotatably installed inside the support base box 12. A second slider 15 is symmetrically installed on the outside of the second bidirectional lead screw 14. The second slider 15 is slidably connected to the support base box 12. The top of the second slider 15 is fixedly connected to the sliding support 4. A second servo motor 13 is installed on one side of the support base box 12 by bolts. The output end of the second servo motor 13 is fixedly connected to the second bidirectional lead screw 14.

[0030] It should be noted that in this embodiment, the output end of the second servo motor 13 drives the second bidirectional lead screw 14 to rotate. When the second bidirectional lead screw 14 rotates, it drives the outer symmetrical second slider 15 to move. When the second slider 15 moves, it drives the sliding support 4 and the top limit slide box 5 to move. The top limit slide box 5, which slides symmetrically on the support base 3, limits the position of the support base 25 and the lower mold 1.

[0031] In one embodiment, such as Figures 1 to 5 As shown, a first bidirectional lead screw 9 is rotatably installed inside the top limit slide box 5. A first slider 10 is symmetrically installed on the outside of the first bidirectional lead screw 9. The first slider 10 is slidably connected to the top limit slide box 5. One side of the first slider 10 is fixedly connected to the positioning clamp 6. A first servo motor 11 is installed on one side of the top limit slide box 5 by bolts. The output end of the first servo motor 11 is fixedly connected to the first bidirectional lead screw 9.

[0032] It should be noted that in this embodiment, the output end of the first servo motor 11 drives the first bidirectional lead screw 9 to rotate. When the first bidirectional lead screw 9 rotates, it drives the outer symmetrical first slider 10 to move. In turn, the first slider 10 drives the positioning clamp 6 and the limiting block 7 to move. The limiting block 7 cooperates with the limiting slot 8 to complete the installation and positioning of the support base 25 and the lower mold 1.

[0033] In one embodiment, such as Figures 1 to 5 As shown, the second slider 15 has a symmetrical sliding limit rod 16 inside, and the limit rod 16 is fixedly connected to the support base box 12.

[0034] It should be noted that in this embodiment, the second slider 15 slides to a limit outside the limiting rod 16, thereby improving the adjustment stability of the second slider 15 and the sliding support 4.

[0035] In one embodiment, such as Figures 1 to 5 As shown, an ejector cylinder 26 is installed inside the lower mold 1 and the support base 25. An ejector plate 24 is slidably arranged on the inner side of the lower mold 1, and the output end of the ejector cylinder 26 is fixedly connected to the ejector plate 24.

[0036] It should be noted that in this embodiment, the ejector plate 24 is moved by the output end of the ejector cylinder 26, and the ejector plate 24 drives multiple ejectors at the top to eject the molded part in the lower mold 1.

[0037] In one embodiment, such as Figures 1 to 5 As shown, the bottom of the upper mold 2 is symmetrically fixed with multiple second guide pillars 21, and the interior of the lower mold 1 is symmetrically fixed with multiple second guide sleeves 22 that cooperate with the second guide pillars 21. The interior of the upper mold 2 is provided with injection flow channels 23.

[0038] It should be noted that, in this embodiment, the No. 2 guide post 21 symmetrically arranged at the bottom of the upper mold 2 cooperates with the No. 2 guide sleeve 22 symmetrically arranged inside the lower mold 1 to improve the stability of the mold closing between the lower mold 1 and the upper mold 2.
