Description

Technical Field

[0001] This utility model relates to the field of refrigerator freezer drawers, specifically a mold for injection molding of refrigerator freezer drawers. Background Technology

[0002] Injection molds are tools used to produce plastic products, and they also give plastic products a complete structure and precise dimensions. The structure of refrigerator drawers processed by existing injection molds is relatively simple, but with the development of refrigerator technology, the structure of refrigerator drawers has also changed significantly.

[0003] When injection molding freezer drawers, the material needs to be injected into the mold. After it has completely cooled, the mold can be disassembled to remove the drawer. However, during the injection molding process, the outside of the drawer may stick to the inside of the mold, making it difficult to demold smoothly. Demolding requires more time, which reduces production efficiency.

[0004] Therefore, a mold for injection molding of refrigerator freezer drawers is proposed to address the above problems. Utility Model Content

[0005] To overcome the shortcomings of existing technology and solve the problem that the outside of the drawer sticks to the inside of the mold during the injection molding process, making it impossible to demold smoothly and requiring more time to demold, thus reducing production efficiency, this utility model proposes a mold for injection molding of refrigerator freezer drawers.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The mold for injection molding of refrigerator freezer drawers of this utility model includes a main mold, a base plate slidably connected inside the main mold, and a demolding assembly provided on the outside of the base plate. The demolding assembly includes four support blocks fixedly connected to the bottom of the base plate. The four support blocks are divided into two groups. Support rods are slidably connected inside each of the two groups of support blocks. A connecting plate is rotatably connected to the outside of the support rods. A slider is rotatably connected inside the connecting plate. A first sliding rod is slidably connected inside the slider. A limiting frame is fixedly connected to the outside of the first sliding rod. The limiting frame is fixedly connected to the outside of the main mold. A first spring is fixedly connected between the slider and the limiting frame.

[0007] Preferably, a pressing component is provided on the outside of the limiting frame. The pressing component includes a pressing tube fixedly connected to the top of the slider. The pressing tube passes through the limiting frame and is slidably connected. A pressure plate is fixedly connected to the top of the pressing tube.

[0008] Preferably, the main mold is provided with an auxiliary component, which includes two mounting seats fixedly connected to the inside of the main mold. A second slide rod is slidably connected inside the mounting seat. An auxiliary module is fixedly connected to the top of the second slide rod. The auxiliary module is slidably connected to the inside of the main mold. A second spring is fixedly connected between the auxiliary module and the mounting seat.

[0009] Preferably, the auxiliary component further includes a handle inner liner fixedly connected to the top of the auxiliary module, and two connecting rods fixedly connected to the outside of the auxiliary module. The connecting rods pass through the main mold and are slidably connected, and a pressing plate is fixedly connected to the end of the connecting rod.

[0010] Preferably, a shaping component is provided on the outside of the main mold. The shaping component includes a main inner liner that is slidably connected to the inside of the main mold. A mold cover is fixedly connected to the top of the main inner liner, and an insert rod is fixedly connected to the bottom of the mold cover. The insert rod is slidably connected to the inside of the main mold.

[0011] Preferably, the support rod passes through the main mold and is slidably connected, and the support rod passes through the support block.

[0012] Preferably, the handle inner liner is set at a lower height than the main body inner liner, and the outer side of the handle inner liner is slidably connected to the inside of the mold cover.

[0013] The advantages of this utility model are: 1. This utility model uses a slider to move the connecting plate, which in turn moves the support rod, allowing the support rod to slide inside the support block. Further pressing of the slider moves the limiting frame downwards, which in turn moves the main mold downwards, causing the base plate to slide inside the main mold. This separates the drawer from the main mold, thus completing demolding. This reduces the difficulty of demolding, shortens the time required for demolding, and improves production efficiency.

[0014] 2. This utility model moves the connecting rod by pressing the pressing plate, which in turn moves the auxiliary module, which in turn moves the second sliding rod, thereby compressing the second spring. When the auxiliary module moves, it can separate the handle inner liner from the drawer, thereby further improving the smoothness of demolding, further reducing the difficulty of demolding, and thus 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 Figures 1-4 As shown, a mold for injection molding a refrigerator freezer drawer includes a main mold 1. A base plate 2 is slidably connected inside the main mold 1. A demolding assembly is provided on the outside of the base plate 2. The demolding assembly includes four support blocks 3 fixedly connected to the bottom of the base plate 2. The four support blocks 3 are divided into two groups. Support rods 4 are slidably connected inside each group of support blocks 3. A connecting plate 5 is rotatably connected to the outside of the support rods 4. A slider 6 is rotatably connected inside the connecting plate 5. A first sliding rod 7 is slidably connected inside the slider 6. A limiting frame 8 is fixedly connected to the outside of the first sliding rod 7. The limiting frame 8 is fixedly connected to the outside of the main mold 1. A first spring 9 is fixedly connected between the slider 6 and the limiting frame 8.

[0020] During operation, pressing the slider 6 moves the connecting plate 5, which in turn moves the support rod 4, allowing the support rod 4 to slide inside the support block 3. Then, pressing the slider 6 again moves the limiting frame 8 downward, which in turn moves the main mold 1 downward, allowing the base plate 2 to slide inside the main mold 1. This separates the drawer from the main mold 1, thus completing demolding. This reduces the difficulty of demolding and the time required for demolding, thereby improving production efficiency.

[0021] The outer side of the limiting frame 8 is provided with a pressing component, which includes a pressing tube 10 fixedly connected to the top of the slider 6. The pressing tube 10 passes through the limiting frame 8 and is slidably connected. A pressure plate 11 is fixedly connected to the top of the pressing tube 10.

[0022] During operation, pressing the pressure plate 11 moves the pressure tube 10, which in turn moves the slider 6.

[0023] The main mold 1 has a shaping component on its outer side. The shaping component includes a main inner liner 19 that is slidably connected to the inside of the main mold 1. A mold cover 20 is fixedly connected to the top of the main inner liner 19. An insert rod 21 is fixedly connected to the bottom of the mold cover 20. The insert rod 21 is slidably connected to the inside of the main mold 1.

[0024] During operation, the mold cover 20 moves, causing the insert rod 21 to enter the main mold 1, thereby causing the main body liner 19 to enter the main mold 1. Then, the mold cover 20 and the main mold 1 are fixed by a fixing device, which facilitates subsequent injection molding.

[0025] Among them, the support rod 4 passes through the main mold 1 and is slidably connected, and the support rod 4 passes through the support block 3.

[0026] During operation, the sliding of the support rod 4 with the main mold 1 and the support block 3 ensures that demolding can proceed smoothly.

[0027] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the main mold 1 is provided with an auxiliary component. The auxiliary component includes two mounting seats 12 fixedly connected inside the main mold 1. A second slide rod 13 is slidably connected inside the mounting seat 12. An auxiliary module 14 is fixedly connected to the top of the second slide rod 13. The auxiliary module 14 is slidably connected to the inside of the main mold 1. A second spring 15 is fixedly connected between the auxiliary module 14 and the mounting seat 12.

[0028] The auxiliary components also include a handle inner tube 16 fixedly connected to the top of the auxiliary module 14. Two connecting rods 17 are fixedly connected to the outside of the auxiliary module 14. The connecting rods 17 pass through the main mold 1 and are slidably connected. A pressing plate 18 is fixedly connected to the end of the connecting rod 17.

[0029] During operation, pressing the pressing plate 18 moves the connecting rod 17, which in turn moves the auxiliary module 14, which in turn moves the second slide rod 13, thereby compressing the second spring 15. When the auxiliary module 14 moves, it can separate the handle inner liner 16 from the drawer, thereby further improving the smoothness of demolding and reducing the difficulty of demolding, thus improving work efficiency.

[0030] The handle inner liner 16 is set at a lower height than the main body inner liner 19, and the outer side of the handle inner liner 16 is slidably connected to the inside of the mold cover 20.

[0031] When in operation, the inner liner 16 of the handle is set lower than the inner liner 19 of the main body, which facilitates the appearance of the drawer handle.

[0032] The working principle is that by pressing the pressing plate 18, the connecting rod 17 is moved, which in turn moves the auxiliary module 14, which in turn moves the second slide rod 13, thereby compressing the second spring 15. When the auxiliary module 14 moves, it can separate the handle inner liner 16 from the drawer, thereby further improving the smoothness of demolding, further reducing the difficulty of demolding, and thus improving work efficiency. Then, by pressing the slider 6, the connecting plate 5 is moved, which in turn moves the support rod 4, allowing the support rod 4 to slide inside the support block 3. Then, by continuing to press the slider 6, the limiting frame 8 is moved down, which in turn moves the main mold 1 down, allowing the base plate 2 to slide inside the main mold 1, thus separating the drawer from the main mold 1 and completing the demolding process. This reduces the difficulty of demolding and the time required for demolding, thereby improving production efficiency.
