Description

Technical Field

[0001] This utility model relates to the field of injection molds, specifically an injection mold for forming refrigerator drawers. Background Technology

[0002] Injection molds are tools used in the plastics processing industry, working in conjunction with plastic molding machines to give plastic products a complete shape and precise dimensions. Due to the wide variety of plastics and processing methods, and the varying complexity of plastic molding machines and products, the types and structures of plastic molds are also diverse. Typically, an injection mold consists of several parts, which together form a molding cavity.

[0003] After the refrigerator drawer is injection molded, it needs to be removed after it cools down. However, because the solution is viscous during injection, the drawer will stick to the inside of the mold even after it cools down. This makes it more time and effort to remove the drawer, which is inconvenient and reduces work efficiency.

[0004] Therefore, an injection mold for forming refrigerator drawers is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technology and solve the problem that even after the drawer cools down, it will stick to the inside of the mold, making it more time-consuming and laborious to remove the drawer, resulting in inconvenience and reduced work efficiency, this utility model proposes an injection mold for forming refrigerator drawers.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The injection mold for forming refrigerator drawers according to this utility model includes a bottom mold, a working component is provided inside the bottom mold, a disassembly component is provided at the bottom of the working component, the disassembly component includes a rotating seat fixedly connected to the bottom of the working component, a lifting rod is rotatably connected inside the rotating seat, a limiting rod is rotatably connected to the outside of the lifting rod, a placement groove is opened inside the bottom mold, the limiting rod is rotatably connected to the inside of the placement groove, and a transmission rod is fixedly connected to the end of the lifting rod.

[0007] Preferably, a pressing assembly is provided on the outside of the transmission rod. The pressing assembly includes two pressing rods rotatably connected to the outside of the transmission rod. A limiting plate is slidably connected to the outside of the pressing rods, and the limiting plate is fixedly connected to the outside of the bottom mold.

[0008] Preferably, the pressing assembly further includes a pressure plate fixedly connected to the top of the pressure rod, and a first spring is fixedly connected between the pressure plate and the limiting plate.

[0009] Preferably, the working component includes a top mold slidably connected to the inner top, a handle forming block fixedly connected inside the bottom mold, a movable plate slidably connected inside the bottom mold, and two limiting strips fixedly connected inside the bottom mold.

[0010] Preferably, the bottom of the movable plate is provided with an auxiliary component, the auxiliary component including a transmission frame fixedly connected to the bottom of the movable plate, a slide rod slidably connected inside the transmission frame, a limit frame fixedly connected to the top of the slide rod, and a second spring fixedly connected between the limit frame and the transmission frame.

[0011] Preferably, the bottom of the movable plate is fixedly connected to the top of the rotating seat, and the bottom of the movable plate abuts against the top of the limiting strip.

[0012] Preferably, the slide bar is fixedly connected to the inside of the bottom mold, and the limiting frame is fixedly connected to the inside of the bottom mold.

[0013] The advantages of this utility model are: 1. This utility model uses a pressing plate to move a pressing rod and compress a first spring, thereby transmitting power to a transmission rod. This causes the lifting rod to rotate along the limiting rod, which in turn causes the rotating seat to rise. The lifting rod then rotates along the rotating seat, causing the movable plate to rise, which in turn causes the cooled drawer to rise, thus separating the drawer from the bottom mold. This facilitates the retrieval of the drawer and subsequent injection molding work, thereby improving the ease of use of the device and increasing work efficiency.

[0014] 2. This utility model uses the lifting of the movable plate to drive the transmission frame to rise, thereby compressing the second spring. When the force acting on the movable plate disappears, the reaction force of the second spring can drive the transmission frame to return to its original position, thus facilitating the return of the movable plate to its original position and making it easier to carry out subsequent injection molding work, thereby improving work efficiency.

[0018] 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.

[0019] Example 1 Please see Figure 1-5 As shown, an injection mold for forming refrigerator drawers includes a bottom mold 1, a working component is provided inside the bottom mold 1, and a disassembly component is provided at the bottom of the working component. The disassembly component includes a rotating seat 6 fixedly connected to the bottom of the working component, a lifting rod 7 rotatably connected inside the rotating seat 6, a limiting rod 8 rotatably connected to the outside of the lifting rod 7, a placement groove 9 is opened inside the bottom mold 1, the limiting rod 8 is rotatably connected inside the placement groove 9, and a transmission rod 10 is fixedly connected to the end of the lifting rod 7.

[0020] During operation, pressing the transmission rod 10 causes the lifting rod 7 to rotate along the limit rod 8, thereby raising the rotating seat 6 and causing the lifting rod 7 to rotate along the rotating seat 6, which in turn raises the movable plate 4, thereby raising the cooled drawer and separating it from the bottom mold 1. This facilitates the retrieval of the drawer and subsequent injection molding work, thus improving the ease of use of the device and increasing work efficiency.

[0021] The transmission rod 10 is provided with a pressing assembly on its outer side. The pressing assembly includes two pressing rods 11 rotatably connected to the outer side of the transmission rod 10. A limiting plate 13 is slidably connected to the outer side of the pressing rods 11. The limiting plate 13 is fixedly connected to the outer side of the bottom mold 1.

[0022] The pressing assembly also includes a pressure plate 12 fixedly connected to the top of the pressure rod 11, and a first spring 14 is fixedly connected between the pressure plate 12 and the limiting plate 13.

[0023] During operation, pressing the pressure plate 12 moves the pressure rod 11 and compresses the first spring 14, thereby transmitting power to the transmission rod 10, which facilitates the lifting of the drawer via the lifting rod 7, thus making demolding easier.

[0024] The working components include a top mold 2 that is slidably connected inside the bottom mold 1, a handle forming block 3 that is fixedly connected inside the bottom mold 1, a movable plate 4 that is slidably connected inside the bottom mold 1, and two limit strips 5 that are fixedly connected inside the bottom mold 1.

[0025] During operation, the top mold 2 moves to combine with the bottom mold 1, which facilitates injection molding. In conjunction with the movable plate 4, it facilitates the forming and demolding of the drawer.

[0026] The bottom of the movable plate 4 is fixedly connected to the top of the rotating seat 6, and the bottom of the movable plate 4 abuts against the top of the limiting strip 5.

[0027] During operation, the rotating seat 6 moves, thereby causing the movable plate 4 to rise, which in turn makes it easier to lift the drawer and facilitate demolding.

[0028] Example 2 Please see Figure 6 As shown in the first embodiment, as another implementation of this utility model, the bottom of the movable plate 4 is provided with an auxiliary component. The auxiliary component includes a transmission frame 17 fixedly connected to the bottom of the movable plate 4. A slide rod 16 is slidably connected inside the transmission frame 17. A limit frame 15 is fixedly connected to the top of the slide rod 16. A second spring 18 is fixedly connected between the limit frame 15 and the transmission frame 17.

[0029] During operation, the lifting of the movable plate 4 causes the transmission frame 17 to rise, which in turn compresses the second spring 18. When the force acting on the movable plate 4 disappears, the reaction force of the second spring 18 can drive the transmission frame 17 to return to its original position, thus facilitating the return of the movable plate 4 to its original position and making it easier to carry out subsequent injection molding work, thereby improving work efficiency.

[0030] The slide bar 16 is fixedly connected to the inside of the bottom mold 1, and the limiting frame 15 is fixedly connected to the inside of the bottom mold 1.

[0031] During operation, the bottom mold 1 can fix the position of the slide rod 16 and the position of the limit frame 15, thereby facilitating the smooth operation of the device.

[0032] The working principle is as follows: by pressing the pressure plate 12, the pressure rod 11 is moved and the first spring 14 is compressed, thereby transmitting power to the transmission rod 10, which in turn drives the lifting rod 7 to rotate along the limit rod 8, thereby driving the rotating seat 6 to rise. The lifting rod 7 rotates along the rotating seat 6, thereby driving the movable plate 4 to rise, thereby driving the cooled drawer to rise, and thus separating the drawer from the bottom mold 1. This makes it easier to take out the drawer and facilitates subsequent injection molding work, thereby improving the ease of use of the device and increasing work efficiency.
