Description

Technical Field

[0001] The utility model provides a processing mold, belongs to the technical field of foam packaging box processing equipment, and particularly relates to a mold for producing and processing foam packaging boxes. Background Art

[0002] Foam packaging boxes are a common packaging material, often used to protect fragile or valuable items from damage during transportation, storage and handling. These boxes are usually made of foam plastic, which is known for its lightweight, shock-absorbing and cushioning properties.

[0003] This type of box is made by injecting foam plastic into the mold and extruding it as a whole. They usually have a sturdy structure and good cushioning performance, suitable for various transportation and storage scenarios. By absorbing shock and vibration, foam boxes can effectively reduce the damage rate of goods during transportation and ensure that the goods arrive at the destination in good condition.

[0004] After the foam packaging box is pressed and formed, the box body and the pressing mold need to be separated. Since the formed foam plastic fits tightly against the inner wall of the mold box, it is very inconvenient to separate and the formed shape may be damaged. In order to achieve portable demoulding, most devices introduce complex mechanical mechanisms. For example, publication number: CN212636296U discloses a forming mold for the production of foam plastic boards, including a base, support rods are symmetrically fixedly connected to the base, a mold box is fixedly connected to the support rods, a motor is provided on the base, a threaded sleeve is fixedly connected to the output end of the motor, a threaded rod is threadedly connected to the inner thread of the threaded sleeve, the upper end of the threaded rod extends into the mold box, a support plate is fixedly connected to the threaded rod, a baffle is symmetrically slidably connected to the mold box, an elastic device is provided on the baffle, and a cover is provided on the mold box. The utility model opens the cover body, and the user slowly pulls the connecting rod outward, and then moves the L-shaped limit rod downward to insert it into the limit groove, so that the foam board is separated from the baffle plate, and then starts the motor to rotate the threaded sleeve, which drives the threaded rod to move upward, so that the support plate moves upward, and the foam board is separated from the mold box. In the above structure, it is necessary to use multiple structures such as the support plate, the threaded rod, and the motor for demolding, and the structure is too complicated.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field of the present invention; the terms used in the specification of the present invention are only for the purpose of describing specific implementation methods and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figure 1 , 2As shown in Figure 5, the utility model provides a mold for producing and processing a foam packaging box, including an outer shell 1, a pressure structure 2 is provided inside the outer shell 1, a limiting plate 11 is provided inside the pressure structure 2 and is placed above the outer shell 1, the pressure structure 2 includes a plurality of pressure blocks 21 that are evenly distributed and close to each other inside the outer shell 1, an inclined surface 22 is provided on the pressure block 21, a sliding surface 23 corresponding to the inclined surface 22 is provided at a corner of the pressure block 21 close to another pressure block, the connection order of the pressure block 21 is that the sliding surface 23 is close to the inclined surface 22, the shape formed in the middle of the pressure block 21 corresponds to the shape of the limiting plate 11, and a hydraulic telescopic device 12 is provided on one side of the outer shell 1, which passes through the outer shell 1 and is fixedly connected to any pressure block 21.

[0028] In this embodiment, a plurality of pressure blocks 21 arranged closely in sequence are provided inside, and with the help of a limiting plate 11 corresponding to the pressure plate 21, the pressure block 21 is pushed by a hydraulic telescopic device 12 so that the pressure structure 2 as a whole shrinks inward in the direction of the limiting plate 11, thereby completing the clamping work. When disengaging, the hydraulic telescopic device 12 is used to pull the pressure block 21 outward to move the pressure structure 2 away from the limiting plate 11, thereby completing the separation of the pressure mold and the box.

[0029] like Figure 3 and Figure 4 As shown, an L-shaped limit plate 13 is connected to the inner side of the upper opening of the outer shell 1, and a sliding groove 14 is formed between the limit plate 13 and the outer shell 1. A sliding plate 24 fixedly connected to the pressure block 21 is provided in the sliding groove 14. The shape of the limit plate 11 is consistent with the shape formed in the middle of the pressure block 21, and the end of the limit plate 11 away from the interior of the outer shell 1 is connected to a cover 15 placed above the outer shell 1.

[0030] In this embodiment, the hydraulic telescopic device 12 pushes a pressurizing block 21 in the pressurizing structure 2. The pressurizing block 21 slides forward as a whole under the restriction of the sliding groove 14 with the help of the sliding plate 24, pushing the sliding surface 23 of the other pressurizing block 21 to slide along the inclined surface 22, so that the whole shrinks.

[0031] It should be noted that the size and number of the internal pressure blocks 21 can be determined according to the shape of the box to be prepared, and the inclined surfaces 22 and the sliding surfaces 23 are kept connected in sequence so that the pressure blocks 21 can be pieced together into different shapes. The shapes of the outer shell 1 and the limiting plate 11 are then set to be the same, and polygonal foam boxes of different shapes can be pressed.

[0032] When in use, first, determine the size and number of the internal pressure blocks 21 according to the shape of the box to be prepared. These pressure blocks 21 should be able to form the shape of the required polygonal foam box; install the pressure blocks 21 in sequence inside the outer shell 1, and ensure that they are closely arranged and fit each other. The pressure blocks 21 are provided with inclined surfaces 22 and sliding surfaces 23 to achieve the operation of retraction and disengagement; the limiting plate 11 is installed above the pressure structure 2 to limit the movement direction of the pressure blocks 21. An L-shaped limit plate 13 is connected to the inner side of the upper end opening of the outer shell 1, and a sliding plate 24 is installed in the sliding groove 14 to limit the movement trajectory of the pressure blocks 21; the pressure blocks 21 are pushed by the hydraulic telescopic device 12, so that the pressure structure 2 as a whole retracts in the direction of the limiting plate 11 to complete the clamping of the foam box. The function of the hydraulic telescopic device 12 is to control the movement of the pressure blocks 21 to ensure the accuracy and stability of the clamping; after the pressure structure 2 completes the clamping, the foam material can be placed inside the outer shell 1 and formed. The foam material will be constrained by the shape of the pressure block 21 and the outer shell 1, thereby forming a polygonal foam box of the desired shape; after the molding is completed, the pressure block 21 is pulled outward by the hydraulic expansion device 12, so that the pressure structure 2 is away from the limiting plate 11, and the separation of the pressure mold and the box is completed. The control function of the hydraulic expansion device 12 is to restore the pressure block 21 to its original position so as to take out the molded foam box. Through the above steps, the utility model mold can be effectively used to prepare a polygonal foam box.

[0033] Although the present invention has been disclosed as above in terms of preferred embodiments, it is not intended to limit the present invention. Anyone familiar with the technology may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be based on the definition of the claims.
