Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a detachable cooling injection mold structure. Background Technology

[0002] Injection molds are tools or devices specifically designed for molding plastics, primarily used to mold various plastic products. Mold design and manufacturing are crucial steps in the injection molding process, determining the shape, size, and surface quality of the plastic products.

[0003] Patent application CN213291163U discloses a dual-guide mechanism for an injection mold base, including an operating table. A movable plate is positioned above the operating table, and a first fixed plate is positioned above the movable plate. The movable plate and the first fixed plate are connected by several first springs. An upper mold is positioned below the movable plate, and the movable plate and the upper mold are connected by an elastic component. A lower mold, which mates with the upper mold, is positioned at the top of the operating table. Two first limiting holes are formed at the top of the movable plate, and support columns are positioned within these holes. The tops of the support columns are fixedly connected to the bottoms of the first fixed plate, and the bottoms of the support columns are fixedly connected to the tops of the operating table. This dual-guide mechanism for an injection mold base belongs to the field of injection mold technology. It allows for buffering between the upper and lower molds during mold closing, thereby reducing damage and facilitating the replacement and maintenance of the electric telescopic rod.

[0004] During the use of injection molds, after the injection mold injects molten liquid into the mold cavity, it is cooled by natural cooling or air cooling. However, after the injection molding is completed, the molded mold tends to stick to the mold and is not easy to demold, which can affect the working efficiency of the equipment. In order to address the above problems, we have introduced a detachable cooling injection mold structure. Utility Model Content

[0005] This utility model discloses a detachable cooling injection mold structure. It studies and improves the existing structure and its shortcomings, and provides a detachable cooling injection mold structure to achieve better practical value.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A detachable cooling injection mold structure includes a base plate, a mounting bracket fixedly connected to the top of the base plate, a lower mold disposed inside the mounting bracket, a first telescopic rod disposed at the top of the mounting bracket, the bottom of the first telescopic rod extending into the interior of the mounting bracket and fixedly connected to a mounting plate, an upper mold fixedly connected to the bottom of the mounting plate, two sliding rods fixedly connected to the top of the mounting plate, the outer sides of the two sliding rods being slidably connected to the interior of the mounting bracket, a limit block fixedly connected to the top of the sliding rods, and a shaking component disposed inside the mounting bracket for swinging the lower mold.

[0007] In a preferred embodiment, the wobbling assembly includes two mounting rods, both of which are slidably connected to a mounting bracket. Nuts are threaded onto the outer sides of the mounting rods, with one end of the nut abutting against one side of the mounting bracket.

[0008] In a preferred embodiment, mounting blocks are fixedly connected at equal intervals to the bottom of the lower mold, the interior of the mounting blocks is slidably connected to the exterior of the mounting rod, and a spring is provided on the exterior of the mounting rod.

[0009] In a preferred embodiment, a fixing plate is fixedly connected to one side of the mounting frame, a drive motor is provided on one side of the fixing plate, a turntable is fixedly connected to one end of the output shaft of the drive motor, a fixing rod is fixedly connected to one side of the turntable, a connecting block is fixedly connected to one side of the lower mold, a connecting rod is rotatably connected between the connecting block and the fixing rod, and a movable groove is provided inside the mounting frame.

[0010] In a preferred embodiment, the bottom of the lower mold is provided with a second telescopic rod, the top of the second telescopic rod extends into the interior of the lower mold and is fixedly connected to a lifting plate, and the outer side of the lifting plate is slidably connected to the interior of the lower mold.

[0011] In a preferred embodiment, a fan is provided inside the mounting bracket, and a controller is provided on the top of the base plate.

[0012] The detachable cooling injection mold structure provided by this utility model has the following advantages: First, after the plastic is injected into the lower mold, the first telescopic rod is activated to extend downwards. Through the constraint of the sliding rod, the mounting plate moves vertically downwards, allowing the upper mold to insert into the lower mold to complete the molding process. A fan is used to accelerate the cooling of the plastic product. Then, the first telescopic rod is retracted, raising the upper mold, while the fan continues to promote further cooling of the plastic. Next, the drive motor rotates the turntable, causing the fixed rod to move in a circular motion. The connecting rod moves in the movable groove, thus pushing the lower mold back and forth. Simultaneously, multiple sets of springs are repeatedly compressed, helping to gradually separate the plastic product from the mold cavity wall. Finally, the second telescopic rod is activated, pushing the lifting plate upwards and ejecting the molded plastic from the mold cavity, completing the demolding process.

[0013] Secondly, by utilizing a shaking component to achieve vibration, the plastic product in the lower mold gradually separates from the mold cavity wall, reducing adhesion and thus accelerating demolding speed and significantly improving production efficiency. The combination of mechanical vibration, translational motion, and spring elasticity achieves smooth shaking, avoiding damage to the plastic product caused by excessive force and ensuring product quality.

All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The detachable cooling injection mold structure disclosed in this utility model is mainly used in injection mold applications.

[0021] Reference Figures 1 to 4 A detachable cooling injection mold structure includes: a base plate 1, a mounting frame 2 fixedly connected to the top of the base plate 1, a lower mold 3 disposed inside the mounting frame 2, a first telescopic rod 4 disposed at the top of the mounting frame 2, the bottom of the first telescopic rod 4 extending into the interior of the mounting frame 2 and fixedly connected to a mounting plate 5, an upper mold 6 fixedly connected to the bottom of the mounting plate 5, two sliding rods 7 fixedly connected to the top of the mounting plate 5, the outer sides of the two sliding rods 7 being slidably connected to the interior of the mounting frame 2, a limit block 8 fixedly connected to the top of the sliding rods 7, and a shaking component disposed inside the mounting frame 2 for swinging the lower mold 3; The wobbling assembly includes two mounting rods 9, both of which are slidably connected to the mounting bracket 2. Nuts 10 are threaded onto the outer side of the mounting rods 9, and one end of the nuts 10 abuts against one side of the mounting bracket 2. The bottom of the lower mold 3 is fixedly connected with mounting blocks 11 at equal intervals. The inside of the mounting blocks 11 is slidably connected to the outside of the mounting rod 9. A spring 12 is provided on the outside of the mounting rod 9. A fixing plate 13 is fixedly connected to one side of the mounting frame 2. A drive motor 14 is provided on one side of the fixing plate 13. A turntable 15 is fixedly connected to one end of the output shaft of the drive motor 14. A fixing rod 16 is fixedly connected to one side of the turntable 15. A connecting block 17 is fixedly connected to one side of the lower mold 3. A connecting rod 18 is rotatably connected between the connecting block 17 and the fixing rod 16. An movable groove 19 is provided inside the mounting frame 2. The bottom of the lower mold 3 is provided with a second telescopic rod 20. The top of the second telescopic rod 20 extends into the interior of the lower mold 3 and is fixedly connected to a lifting plate 21. The outer side of the lifting plate 21 is slidably connected to the interior of the lower mold 3.

[0022] In the above technical solution, considering the problem that after the injection mold injects molten liquid into the mold cavity, it is cooled naturally or by air, but the molded model tends to stick to the mold after injection and is difficult to demold, which can affect the working efficiency of the device, the specific operation is as follows: Plastic is injected into the lower mold 3, then the first telescopic rod 4 is extended downwards. Using the constraint of the sliding rod 7, the mounting plate 5 is moved vertically downwards, allowing the upper mold 6 to enter the lower mold 3 for molding. After the initial movement, the first telescopic rod 4 is activated, moving the upper mold 6 upwards. Then, using the shaking assembly, the drive motor 14 is activated, rotating the turntable 15 and causing the fixed rod 16 to rotate. The connecting rod 18 moves within the movable groove 19, driving the lower mold 3 to shake back and forth. The mounting block 11 moves left and right on the surface of the mounting rod 9, and multiple sets of springs 12 are repeatedly compressed, causing the plastic in the lower mold 3 to gradually separate from its inner wall. Finally, the second telescopic rod 20 is activated, pushing the lifting plate 21 upwards, using the lifting plate 21 to push the plastic up, completing the demolding. By using the shaking assembly to achieve vibration, the plastic product in the lower mold 3 gradually separates from the mold cavity wall, reducing adhesion and thus accelerating the demolding speed, significantly improving production efficiency. The combination of mechanical vibration, translational motion, and the elasticity of the springs 12 achieves smooth shaking, avoiding damage to the plastic product caused by excessive force and ensuring product quality.

[0023] Reference Figures 1 to 4 In a preferred embodiment, a fan 22 is provided inside the mounting bracket 2, and a controller 23 is provided on the top of the base plate 1; the cooling of the plastic product can be accelerated by using the fan 22.

[0024] Working principle: In use, plastic is injected into the lower mold 3, and then the first telescopic rod 4 is activated to extend downwards. With the restriction of the sliding rod 7, the mounting plate 5 is moved vertically downwards, allowing the upper mold 6 to enter the lower mold 3 for molding. The cooling of the plastic product can be accelerated by using the fan 22. The first telescopic rod 4 is activated to move the upper mold 6 upwards, and the fan 22 is used to further accelerate the cooling of the plastic product. The drive motor 14 is activated to drive the turntable 15 to rotate, and the fixed rod 16 to perform a circular motion. The connecting rod 18 moves inside the movable groove 19, which then drives the lower mold 3 to shake back and forth. The mounting block 11 moves left and right on the surface of the mounting rod 9. Multiple sets of springs 12 are repeatedly compressed, causing the plastic in the lower mold 3 to slowly separate from its inner wall. Finally, the second telescopic rod 20 is activated to push the lifting plate 21 upwards, and the lifting plate 21 pushes the plastic up, completing the demolding.
