Description

Technical Field

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

[0002] Foldable storage boxes have the advantages of being easy to store and easy to carry and transport. At present, foldable storage boxes are generally made of plastic materials because plastic materials have good processing performance and mechanical properties and low raw material costs. At present, the foldable storage box is divided into five parts, namely the bottom and four sides (some will have a lid), which are respectively formed by injection molding, and then the five injection-molded parts are assembled to obtain a foldable storage box. This is because the storage box is composed of at least five surfaces, and the five surfaces need to be detachable and foldable. The current injection mold cannot achieve one-time injection molding of such products, so there is currently no one-piece foldable storage box; and the one-piece foldable storage box not only has the advantages of being easy to store and carry and transport, but also has the advantages of not requiring manual assembly and not requiring the design and manufacture of molds for multiple different parts. Summary of the invention

[0003] The object of the present invention is to provide an injection molding mold for an integrated foldable storage box, and more particularly to provide a mold and a molding method that can realize one-time integrated injection molding of the foldable storage box.

[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 cooperatively connected 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 drivingly connected to the movable mold, and the second mold opening drive mechanism is arranged on the fixed mold and drivingly 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] A method for forming an integrated foldable storage box adopts the above-mentioned injection molding mold of the integrated foldable storage box, and sequentially performs mold closing, injection molding, and mold opening to obtain an integrated foldable storage box finished product.

[0010] 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 surfaces 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.

DETAILED DESCRIPTION

[0012] Example 1, reference 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, and a second mold cavity 42 communicating with the first mold cavity 21 being formed between the inner side of the sliding mold 3 and the side surface 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 in the direction of mold opening of the movable mold 2, the side slider 32 being slidably connected to the fixed mold 1, the side slider 32 being movable in the lateral direction of the fixed mold 1, the mold body 31 being drivingly connected to the side slider 32 by a driving oblique rod 33, and when the mold body 31 moves toward the direction of mold opening of the movable mold 2, the side slider 32 is driven to move toward the outer side of the fixed mold 1 by the driving oblique rod 33.

[0013] In this embodiment, the fixed mold 1 is fixedly arranged on the injection molding processing table, the movable mold 2 can be opened and closed and arranged 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 mold opening direction 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 inclined rod 33, thereby completing the mold opening operation, and 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 be provided with a snap-fit ​​structure at the side edge for connecting and fixing with the adjacent side). In this embodiment, the first mold cavity 41 is used for injection molding the bottom surface and two opposite side surfaces of the foldable storage box, and the second mold cavity 42 is used for molding the other two opposite side surfaces of the foldable storage box. By setting the second mold cavity 42 for molding the other two opposite side surfaces on the side surface of the fixed mold core 11, the conflict between the two side surfaces molded in the second mold cavity 42 and the two side surfaces molded in the first mold cavity 41 at the connection after folding can be avoided, thereby realizing the one-piece molding of the foldable storage box, and effectively improving the processing efficiency of the foldable storage box.

[0014] Specifically, the driving inclined 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 inclined groove 34 which is matched and connected with the driving inclined rod 33 .

[0015] In addition, in order to realize automatic mold opening, the present embodiment further includes a first mold opening drive mechanism 51 and a second mold opening drive mechanism 52. The first mold opening drive mechanism 51 is connected to the movable mold 2 by driving, and the second mold opening drive mechanism 52 is arranged on the fixed mold 1 and 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 be separated from the fixed mold 1 by driving the inclined rod 33 to drive the side slider 32 to slide horizontally.

[0016] Furthermore, in order to realize automatic ejection, an ejection mechanism 6 is provided on the fixed mold 1, and the ejection mechanism 6 is provided 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 connected to the ejection rods 61. At least five ejection rods 61 can ensure that at least one corresponding ejection rod 61 is used for ejection on the five surfaces of the storage box after injection molding. Ejection rods 61 can also be added at different positions according to needs to achieve a good ejection effect. After the mold is opened, the ejection drive mechanism 62 drives the ejection rod 61 to eject the injection-molded foldable storage box from the fixed mold core 11 of the fixed mold 1.

[0017] Based on the above description of the injection molding mold, this embodiment also provides an imaging method for an integrated foldable storage box, which adopts the above-mentioned injection molding mold of an integrated foldable storage box, and performs mold closing, injection molding, and mold opening in sequence to obtain an integrated foldable storage box finished product.
