DETAILED DESCRIPTION

[0024] For better understanding and implementation, the technical scheme in the embodiment of the utility model will be clearly and completely described in the embodiment of the utility model in conjunction with the drawings.

[0025] In the description of the utility model, it needs to be explained that the orientation or position relationship indicated by terms "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like is the orientation or position relationship based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and is not intended to indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, so it cannot be understood as a limitation on the utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which the utility model belongs. The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0027] Reference Figs. 1 to 3The utility model discloses a kind of moulds of vehicle control box, comprising: mould main body 10, ejection assembly and driving assembly, mould main body 10 includes first mould group 11 and second mould group 12, driving assembly is used to drive first mould group 11 and second mould group 12 mutually close or is far away, first mould cavity is equipped in the bottom of first mould group 11, second mould cavity is equipped in the top of second mould group 12, so that first mould group 11 and second mould group 12 mutually close when forming cavity 13 is formed;

[0028] In addition, the ejection assembly includes a first ejection mechanism and a second ejection mechanism 30, the first ejection mechanism and the second ejection mechanism 30 are oppositely arranged, the first ejection mechanism is movably connected with the first mould group 11 and can move from top to bottom along the height direction of the mould main body 10 under stress to extend into or exit the forming cavity 13, while the second ejection mechanism 30 is movably connected with the second mould group 12 and can move from bottom to top along the height direction of the mould main body 10 under stress to extend into or exit the forming cavity 13.

[0029] On the basis of the above structure, during assembly, the first ejection mechanism and the second ejection mechanism 30 can be movably arranged at the upper and lower ends of the mould main body 10 respectively, so that they are oppositely arranged. When the product in the forming cavity 13 is formed, the driving assembly drives the first mould group 11 and the second mould group 12 to move away from each other. At the same time, the first ejection mechanism moves from top to bottom along the height direction of the mould main body 10 towards the product in the forming cavity 13 under external force until the top of the product is separated from the first mould group 11. At this time, the top of the product is separated from the first mould group 11, and the forming cavity 13 is also opened. Then, the second ejection mechanism 30 moves from bottom to top along the height direction of the mould main body 10 towards the forming cavity 13 under external force until it extends into the forming cavity 13 to eject the bottom of the product away from the second mould group 12. At this time, the operator can take out the product.

[0030] In specific use, since the vehicle control box usually has a relatively complex internal circuit structure and shell shape, if only one side is provided with an ejection mechanism, the product may be deformed due to uneven stress when demoulding, for example, when only the lower mould has an ejection mechanism, one side of the control box may be caused to sag or warp due to a large ejection force during the ejection process. Therefore, in the utility model, the first ejection mechanism and the second ejection mechanism 30 are arranged to enable the two ejection mechanisms oppositely arranged above and below to exert force simultaneously during the demoulding process, so as to act on the product from two opposite directions to ensure that the product maintains its original shape during the demoulding process and avoids damaging the internal circuit board and other precision components.

[0031] More specifically, relying solely on an ejector mechanism on one side may require a large ejection stroke and ejection force to completely demold the product. When both the first module 11 and the second module 12 are equipped with ejector mechanisms, the simultaneous action of both sides can reduce the ejection stroke of each ejector mechanism. At the same time, since the ejection force is shared by both sides, the required ejection force of a single ejector mechanism will also be reduced. This helps to reduce the strength requirements of the mold and ejector mechanism while ensuring smooth demolding of the product, and extends the service life of the mold and ejector mechanism.

[0032] It should be noted that in this embodiment, both the first ejection mechanism and the second ejection mechanism 30 can be existing ejector pin ejection mechanisms, ejector rod ejection mechanisms, or push plate ejection mechanisms. Specifically, both the first ejection mechanism and the second ejection mechanism can be driven by springs. For example, the first module 11 and the second module 12 can be connected to the first ejection mechanism and the second ejection mechanism 30 by springs, respectively. When the mold is closed, the spring is compressed to store energy. When the mold is opened, the spring releases energy to push the ejection mechanism upward to achieve the ejection of the product. Of course, the first ejection mechanism 20 and the second ejection mechanism can also be driven by hydraulic or cylinder drive mechanisms.

[0033] Furthermore, the first ejection mechanism 20 includes a first push plate 21, a first ejector 22, and an elastic member 23. The first ejector 22 is connected to the first push plate 21 and is disposed toward the molding cavity 13. One end of the elastic member 23 abuts against the outside, and the other end of the elastic member 23 is connected to the first push plate 21 and is used to provide an elastic stress to drive the first push plate 21 to move from top to bottom along the height direction of the mold body 10, so as to drive the first ejector 22 to extend into the molding cavity 13.

[0034] Specifically, when the mold body 10 is closed, the first module 11 and the second module 12 approach each other, and the outer peripheries of the first module 11 and the second module 12 are pressed by the mold locking mechanism. At this time, the elastic component 23 is compressed under pressure, causing the first push plate 21 to move away from the molding cavity 13. At this time, the first ejector will also exit the molding cavity 13. When the product molding requires mold opening, the clamping force on the first module 11 disappears. At this time, the elastic component 23 restores its own deformation, driving the first push plate 21 to move the first ejector toward the molding cavity 13, ejecting the product, so that the product is separated from the first module 11.

[0035] It should be noted that during assembly, the first push plate 21 can be connected to the first module 11 by a sliding connection, so that it can slide up and down in the height direction of the mold body 10 when subjected to force, thereby driving the first ejector 22 to move closer to or away from the molding cavity 13.

[0036] In addition, the elastic component 23 in the embodiment can be a spring or an elastic column, and the first ejector can be a needle or a rod.

[0037] Further, the first ejecting mechanism 20 further comprises a linkage rod 24, one end of the linkage rod 24 is connected with the first push plate 21, and the other end of the linkage rod 24 is connected with the elastic component 23. The elastic component 23 can provide an elastic stress to drive the linkage rod 24 to move close to the forming cavity 13, so that the first push plate 21 moves close to the forming cavity 13.

[0038] Specifically, if the push plate is directly pushed by the elastic component 23 (such as a spring), due to the elastic deformation characteristics of the elastic component 23, the pushing force at different positions may be uneven due to the change of the local resistance of the first push plate 21, and the first push plate 21 may be inclined, resulting in uneven force on the product. Therefore, in the embodiment, the elastic component 23 is connected with the first push plate 21 through the linkage rod 24. The linkage rod 24 can guide and transmit force, and the elastic force of the elastic component 23 is uniformly transmitted to each part of the first push plate 21, so that the first push plate 21 moves vertically to the product surface under the driving of the elastic component 23, and the force exerted by the first push plate 21 on the product is more uniform and stable, which is beneficial to the smooth demolding of the product.

[0039] As a preferred, the elastic component 23 in the embodiment is a spring, and one end of the spring is abutted with an external structure (such as a locking mechanism or a pressing plate outside the first mold group 11), and the other end of the spring is sleeved on the linkage rod 24.

[0040] More specifically, the elastic component 23 and the linkage rod 24 in the embodiment are both provided with a plurality of corresponding elastic components 23 and linkage rods 24, so that the plurality of elastic components 23 can provide greater elastic force through the common action, thereby providing more ejecting force to drive the plurality of linkage rods 24 to push the first push plate 21 at the same time, so that the first push plate 21 is more easily driven to eject the product by the first ejector 22.

[0041] Further, the first ejector 22 is provided with a plurality of first ejectors 22, which are distributed on the top of the first push plate 21.

[0042] Specifically, the plurality of first ejectors 22 can complete the ejection of the product in a shorter time, and compared with a single first ejector 22, they can share the ejection task, reduce the ejection stroke and ejection force required by each first ejector 22, so that the product is demolded faster and the demolding efficiency is improved.

[0043] In addition, the product in the mold can have a complex shape and structure, and uniform force is needed to avoid deformation or damage when demolding. By providing a plurality of first ejection members 22, the ejection force can be uniformly distributed on different parts of the product, reducing the risk of deformation of the product due to local stress during ejection.

[0044] Further, the top of the first mold group 11 is provided with a first mounting cavity 111, and the first ejection mechanism is mounted in the first mounting cavity 111. The top of the first mold group 11 is also provided with a cover plate 112, which covers the first mounting cavity 111. The bottom of the cover plate 112 abuts against the end of the elastic member 23 away from the molding cavity 13.

[0045] Specifically, by providing the first mounting cavity 111 to mount the first ejection mechanism 20, and then covering the first mounting cavity 111 from above by the cover plate 112, the ejection assembly is not easily contaminated by impurities in the external environment after installation. In addition, by providing the first mounting cavity 111, the first ejection mechanism has a space for upward and downward movement, so that it can move up and down in the height direction of the first mounting cavity 111 after being stressed.

[0046] It should be noted that the cover plate 112 can be connected to the first mold group 11 by snap connection or through connecting members such as screws or bolts.

[0047] Further, the second ejection mechanism 30 includes a driving member, a second push plate 31, and a second ejection member 32. The second ejection member 32 is connected to the second push plate 31, and the driving member drives the second push plate 31 to move from bottom to top in the height direction of the mold body 10, so that the second ejection member 32 extends into or exits the molding cavity 13.

[0048] In specific use, the power output end of the driving member is connected to the second push plate 31, so that the second push plate 31 is driven by the driving member to move from bottom to top in the height direction of the mold body 10, thereby driving the second ejection member to extend into the molding cavity 13 to eject the product. When the product is ejected, the driving member again drives the second push plate 31 to move from top to bottom in the height direction of the mold body 10, so that the second ejection member 32 exits the molding cavity 13.

[0049] It should be noted that during assembly, the second push plate 31 can be connected to the second mold group 12 in a sliding manner, so that it slides up and down in the height direction of the mold body 10 when stressed. The driving member can be a hydraulic drive, a pneumatic drive, or a drive motor.

[0050] In addition, the second ejection member 32 in the present embodiment can also adopt a structure of a ejector pin or a ejector rod.

[0051] More specifically, the bottom of the second mold set is further provided with a second installation cavity, and the second ejection mechanism 30 is arranged in the second installation cavity, so that the second ejection mechanism 30 has a space for movement in the height direction of the mold.

[0052] Further, the mold body 10 is provided with an injection flow channel, which is communicated with the forming cavity 13.

[0053] In specific use, the injection flow channel is communicated with the nozzle of the injection molding machine through a pipeline, so that the processing raw material in the injection molding machine is transported from the nozzle of the injection molding machine to the forming cavity 13 in the mold body 10.

[0054] The technical means disclosed in the utility model scheme is not limited to the technical means disclosed in the above-mentioned embodiments, and also includes the technical scheme composed of any combination of the above technical features. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principles of the utility model, and these improvements and refinements are also regarded as the protection scope of the utility model.
