Description

Technical Field

[0001] This utility model belongs to the field of box foaming mold technology, specifically relating to a box foaming mold frame. Background Technology

[0002] Foaming molding involves directly filling a mold with foaming resin, which is then heated and melted to form a gas-liquid saturated solution. Through nucleation, numerous tiny bubble nuclei are formed, which grow to create foam plastic parts. Currently, after the refrigerator body is made into foam plastic parts, workers need to manually open the upper mold to remove the material. This not only increases the workload for workers but also slows down the material removal process, reducing production speed.

[0003] For example, patent CN209158738U discloses a refrigerator body foaming mold rack. By starting a cylinder to drive the extension rod to extend, the upper mold of the cabinet can be lifted. When the starting motor drives the transmission screw to rotate, the slide seat adapted to the transmission screw can drive the pulley under the lower mold of the cabinet to move to the left in the slide groove, so that the lower mold of the cabinet is away from the upper mold of the cabinet, and then the material is picked up. This foaming mold rack does not require workers to manually lift the upper mold of the cabinet, reducing the labor intensity of workers and improving the production speed.

[0004] However, after the foam plastic parts in the mold frame are formed, their outer surface will stick tightly to the inner wall of the lower mold. Therefore, even if the mold frame can automatically lift the upper mold, it is not easy for the staff to remove the foam plastic parts that are sticking tightly to the inner wall of the lower mold.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention features a lifting mechanism. When the motor is started, causing the threaded rod to rotate and slide the lower mold to the right along the upper side of the worktable, the second gear at its outer end rotates at the upper end of the second gear rod. This causes the rotating rod and the first gear to rotate together, simultaneously driving the third gear rod to slide along the inner side of the sliding hole and through groove. Consequently, the base plate slides upwards along the inner side of the lower mold, allowing the foam plastic part located above the base plate in the worktable to be lifted, making it easier for workers to remove the plastic part from the lower mold.

[0018] This invention features a mold-opening mechanism. When the second gear rotates on top of the second rack, it drives the first rack to move upward along the inner side of the limiting hole inside the limiting sleeve. This lifts the upper mold from the top of the lower mold. After the foam plastic part in the lower mold is formed, the upper mold is automatically lifted while the lower mold moves to the right. This eliminates the need for workers to lift the upper mold, reducing the labor intensity of workers and increasing production speed. Attached Figure Description

Detailed Implementation

[0025] 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.

[0026] This specific embodiment is a foaming mold frame for a box, and its structural schematic diagram is shown below. Figures 1 to 3 As shown, the device includes a workbench 1, with support columns 2 fixedly connected to the four lower corners of the workbench 1. A lower mold 3 is connected to the upper side of the workbench 1, and an upper mold 4 is installed at the upper end of the lower mold 3. An opening mechanism is installed at the upper end of the workbench 1, and lifting mechanisms are installed at both the inner and outer ends of the lower mold 3. The opening mechanism includes a top plate 501 fixedly connected to the middle position of the front and rear sides of the upper mold 4. A first toothed rod 502 is fixedly connected to the lower side of the top plate 501. Limit sleeves 503 are fixedly connected to the upper ends of the front and rear sides of the lower mold 3. Limit holes are opened inside the limit sleeves 503. The first toothed rod 502... The outer side is slidably connected to the inner side of the limiting hole. The left end of the second gear 611 meshes with the right end of the first gear 502. Thus, when the second gear 611 rotates above the second gear 605, it will drive the first gear 502 to move upward along the inner side of the limiting hole inside the limiting sleeve 503. This will lift the upper mold 4 from the upper end of the lower mold 3. After the foam plastic part in the lower mold 3 is formed, the upper mold 4 will be automatically lifted while the lower mold 3 is driven to move to the right. This eliminates the need for workers to lift the upper mold 4, reducing the labor intensity of workers and increasing production speed.

[0027] Cooperate Figure 4 The lifting mechanism includes a fixed plate 601 fixedly connected to the upper left end of the worktable 1. A motor 602 is installed on the left side of the fixed plate 601. A threaded rod 603 is installed on the right end of the output shaft of the motor 602. A support block 604 is fixedly connected to the upper right end of the worktable 1. A support hole is opened inside the support block 604. The outer side of the right end of the threaded rod 603 is rotatably connected to the inner side of the support hole. Thus, when the output shaft of the motor 602 is started and rotates, driving the threaded rod 603 to rotate, the end of the threaded rod 603 away from the motor 602 will move in the support hole, thereby enabling the threaded rod 603 to move stably.

[0028] The lower mold 3 has a threaded hole at its lower end. The outer side of the threaded rod 603 is threaded to the inner side of the threaded hole. The upper side of the workbench 1 is slidably connected to the lower side of the lower mold 3. The front and rear ends of the upper side of the workbench 1 are fixedly connected to the second gear 605. The inner side of the lower mold 3 is slidably connected to the base plate 606. The lower side of the base plate 606 is fixedly connected to the third gear 607. Bearings 608 are installed below the front and rear ends of the lower mold 3. A rotating rod 610 is fixedly connected to the inner side of the bearing 608. A first gear 609 is fixedly connected to the middle position of the outer side of the rotating rod 610. The outer sides of the front and rear ends of the rotating rod 610 are fixedly connected to the second gear 611. The right end of the third gear 607 meshes with the left end of the first gear 609. The upper end of the second gear 605 meshes with the second gear 609. The lower end of wheel 611 is engaged, the bottom end of the lower mold 3 has a sliding hole, and the inner transverse position of the workbench 1 has a through groove. The outer side of the third gear 607 is slidably connected to the inner side of the sliding hole and the through groove. Thus, when the motor 602 is started and the threaded rod 603 rotates, causing the lower mold 3 to slide to the right along the upper side of the workbench 1, the second gear 611 at its outer end will rotate at the upper end of the second gear 605, thereby causing the rotating rod 610 and the first gear 609 to rotate together. At the same time, it will drive the third gear 607 to slide along the inner side of the sliding hole and the through groove, thereby causing the base plate 606 to slide upward on the inner side of the lower mold 3. At this time, the foam plastic part located above the base plate 606 in the workbench 1 can be lifted, making it easier for the workers to remove the plastic part from the lower mold 3.

[0029] Working principle: When the foam plastic part in the lower mold 3 needs to be removed, the motor 602 is started, causing the threaded rod 603 to rotate and drive the lower mold 3 to slide to the right along the upper side of the worktable 1. At the same time, the second gear 611 at its outer end rotates above the second gear 605, which will drive the first gear 502 to move upward along the inner side of the limiting hole inside the limiting sleeve 503, gradually lifting the upper mold 4. At the same time, the rotating rod 610 and the first gear 609 rotate together with the second gear 611, driving the third gear 607 to slide along the sliding hole. The bottom plate 606 slides upwards on the inner side of the groove, thereby lifting the foam plastic part above the bottom plate 606 in the workbench 1. The rising rate of the first toothed rod 502 is greater than the rising rate of the third toothed rod 607. When the bottom mold 3 moves to the upper right side of the workbench 1, the upper mold 4 is lifted away from the bottom mold 3. At the same time, the foam plastic part in the bottom mold 3 is lifted out of the bottom mold 3 by the bottom plate 606. Then the worker can quickly take out the foam plastic part and carry out the next work.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
