Description

Technical Field

[0001] The utility model relates to the technical field of injection molds, in particular to an injection molding mold of an integrated foldable storage box. Background Art

[0002] Foldable storage boxes offer advantages such as ease of storage and portability. Currently, foldable storage boxes are generally made of plastic due to its excellent processing and mechanical properties and low raw material costs. Current foldable storage boxes are formed by injection molding five components: a bottom and four side panels (some also include a lid). These components are then assembled to create the foldable box. This is because a storage box consists of at least five surfaces, each of which must be removable and foldable. Current injection molds are unable to achieve this type of product through a single injection molding process, resulting in the lack of a one-piece foldable storage box. A one-piece foldable storage box not only offers the advantages of easy storage and portability, but also requires no manual assembly or the design and manufacture of molds for multiple components. Utility Model Content

[0005] Specifically, the driving oblique rod is fixedly connected to the side sliding block of the sliding die, and the die body of the sliding die is provided with a driving oblique groove which is matched with the driving oblique rod.

[0006] Specifically, it also includes a first mold opening drive mechanism and a second mold opening drive mechanism, the first mold opening drive mechanism is connected to the movable mold, and the second mold opening drive mechanism is arranged on the fixed mold and connected to the mold body of the sliding mold.

[0007] Specifically, a material ejecting mechanism is provided on the fixed mold, and the material ejecting mechanism is provided at the bottom of the fixed mold and passes through the fixed mold core.

[0008] Specifically, the ejecting mechanism includes at least five ejecting rods and an ejecting driving mechanism drivingly connected to the ejecting rods.

[0009] The beneficial effect of the present invention is that by adding a sliding mold that can slide sideways on the basis of the conventional upper and lower mold structures, the five sides of the foldable storage box can be integrally formed, thereby eliminating the need to use multiple molds to process multiple components separately, which not only reduces the processing cost, but also eliminates the need for subsequent manual assembly, thereby improving the processing efficiency of the foldable storage box.

[0015] Example 1, with reference to Figure 1-4, an injection molding mold for an integrated foldable storage box, comprising a fixed mold 1, a movable mold 2 and a sliding mold 3 arranged between the fixed mold 1 and the movable mold 2, the sliding mold 3 being slidably connected to the fixed mold 1, the fixed mold 1 being provided with a fixed mold core 11, a first mold cavity 41 being formed between the movable mold 2 and the fixed mold core 11 of the fixed mold 1, a second mold cavity 42 communicating with the first mold cavity 21 is formed between the inner side of the sliding mold 3 and the side of the fixed mold core 11; the sliding mold 3 comprises a mold body 31 and a side slider 32, the mold body 31 being sleeved on the outer side of the fixed mold core 11 and being movable along the mold opening direction of the movable mold 2, the side slider 32 being slidably connected to the fixed mold 1, the side slider 32 being movable along the side direction of the fixed mold 1, the mold body 31 being driven and connected to the side slider 32 by driving the oblique rod 33, and when the mold body 31 moves toward the mold opening direction of the movable mold 2, the side slider 32 is driven to move toward the outer side of the fixed mold 1 by driving the oblique rod 33.

[0016] In this embodiment, the fixed mold 1 is fixedly set on the injection molding processing table, the movable mold 2 can be opened and closed and is set above the fixed mold 1, and the sliding mold 3 is located between the movable mold 1 and the fixed mold 2, and the sliding mold 3 includes a mold body 31 and a side slider 32, wherein the mold body 31 is sleeved on the outside of the fixed mold core 11 and can move along the direction of the mold opening of the movable mold 2. When the injection molding is completed and the mold is opened, the movable mold 2 is first moved upward to separate from the fixed mold 1, and then the mold body 31 is driven upward so that the mold body 31 drives the side slider 32 to slide horizontally and separate from the fixed mold 1 through the driving rod 33, thereby completing the mold opening operation. The mold closing operation is the opposite of the above steps. Figure 5 , which is a schematic diagram of the approximate structure of the foldable storage box after injection molding (the actual foldable storage box needs to have a snap-fit ​​structure at the side edge for connecting and fixing with the adjacent side faces). In this embodiment, the first mold cavity 41 is used for injection molding the bottom surface and two opposite side faces of the foldable storage box, and the second mold cavity 42 is used for molding the other two opposite side faces of the foldable storage box. By setting the second mold cavity 42 for molding the other two opposite side faces on the side of the fixed mold core 11, the conflict between the two side faces molded in the second mold cavity 42 and the two side faces molded in the first mold cavity 41 at the connection point after folding can be avoided, thereby realizing the one-piece molding of the foldable storage box, effectively improving the processing efficiency of the foldable storage box.

[0017] Specifically, the driving oblique rod 33 is fixedly connected to the side slider 32 of the sliding die 3 , and the die body 31 of the sliding die 3 is provided with a driving oblique groove 34 that cooperates with the driving oblique rod 33 .

[0018] In addition, to achieve automatic mold opening, this embodiment also includes a first mold opening drive mechanism 51 and a second mold opening drive mechanism 52. The first mold opening drive mechanism 51 is drivably connected to the movable mold 2, and the second mold opening drive mechanism 52 is disposed on the fixed mold 1 and drivably connected to the mold body 31 of the sliding mold 3. The first mold opening drive mechanism 51 is used to drive the movable mold 2 to move upward and separate from the fixed mold 1, and the second mold opening drive mechanism 52 is used to drive the mold body 31 of the sliding mold 3 to move upward, so that the mold body 31 can drive the inclined rod 33 to drive the side slider 32 to slide horizontally and separate from the fixed mold 1.

[0019] Furthermore, in order to realize automatic ejection, a ejection mechanism 6 is provided on the fixed mold 1, and the ejection mechanism 6 is arranged at the bottom of the fixed mold 1 and passes through the fixed mold core 11. The ejection mechanism 6 includes at least five ejection rods 61 and an ejection drive mechanism 62 driven by the ejection rods 61. At least five ejection rods 61 can ensure that there is at least one corresponding ejection rod 61 for ejection on the five sides of the storage box after injection molding. Ejection rods 61 can also be added at different positions as needed to achieve a good ejection effect. After the mold is opened, the ejection drive mechanism 62 drives the ejection rods 61 to eject the injection-molded foldable storage box from the fixed mold core 11 of the fixed mold 1.

[0020] Of course, the above are only preferred implementation methods of the present invention, and are not intended to limit the scope of use of the present invention. Therefore, any equivalent changes based on the principles of the present invention should be included in the scope of protection of the present invention.
