Description

Technical Field

[0001] The utility model relates to the technical field of foam molds, and particularly to an internal mechanism of a foam mold that can be dynamically adjusted. Background Technique

[0002] The internal mechanism of a foam mold is a mold used for manufacturing foam plastic products. The internal mechanism of this mold can be adjusted as needed to adapt to the manufacturing of foam plastic products with different shapes and sizes. Foam plastic products are everywhere in our lives, from packaging materials to building insulation, from automotive parts to the casings of electronic products. As a key tool for manufacturing foam plastic products, the quality and performance of the foam mold directly affect the quality and production efficiency of foam plastic products.

[0003] With the continuous progress of technology, the technology of foam molds is also constantly developing. Traditional foam molds are usually manufactured by mechanical processing. This method not only has low efficiency but also is difficult to guarantee accuracy. To solve these problems, modern foam molds usually use CAD / CAM technology for design and manufacturing. This technology can greatly improve the manufacturing efficiency and accuracy of the mold.

[0004] In addition, modern foam molds also adopt advanced heating systems and control systems to ensure the heating uniformity and temperature control accuracy of the mold. At the same time, the internal structure of the mold is constantly optimized to improve the opening and closing speed and service life of the mold.

[0005] The mold usually consists of parts such as a mold body, an internal mechanism, a heating system, and a control system. When manufacturing foam plastic products, the foam plastic raw material is injected into the mold, and then the mold is heated to a certain temperature by the heating system to make the foam plastic raw material foam and solidify into a shape. During this process, the internal mechanism of the mold can be dynamically adjusted as needed to ensure that the shape and size of the foam plastic product meet the requirements.

[0006] The internal structure of the mold usually includes parts such as a core, a cavity, a slider, and a push rod. These parts can be driven and controlled by mechanical, hydraulic, or electric means to realize actions such as the opening and closing of the mold, the extraction of the core, and the movement of the slider.

[0007] The existing internal mechanism of the dynamically adjustable foam mold generally aims to improve the problem that it is not applicable to adjusting foam boards of various different sizes, resulting in poor practicability of the foam embossing mold. For example, a foam embossing mold with an adjusting function disclosed in the authorized Chinese patent CN211730324U can realize the embossing of the foam board through the cooperation of structures such as a base, a motor A, a switch A, a working groove, a slide rail A, a slider A, a hydraulic press, a switch B, a hydraulic rod, a vertical plate, a horizontal plate, a chute, a motor B, a switch C, a rotating shaft, a connecting plate, a slide rail B, a slider B, and an embossing rope, avoiding manual embossing, reducing labor costs, and improving the quality of the finished foam board.

[0008] However, when the internal mechanism of the dynamically adjustable foam mold in the above cited document is in use, due to the limitations in the design and structure of the existing foam mold, it is not convenient for full - range dynamic adjustment. The structure of the traditional foam mold is relatively fixed and lacks flexibility. During the manufacturing process, each part of the mold is usually fixedly connected and cannot be flexibly adjusted as needed. This makes it difficult for the mold to achieve full - range dynamic adjustment when dealing with foam boards of different shapes and sizes, thus restricting the diversity and complexity of the foam boards.

[0009] In summary, due to its fixed structure and cumbersome operation, the existing foam mold is not convenient for full - range dynamic adjustment, which restricts the quality of the finished foam board and further affects the production efficiency of foam plastic products. Utility Model Content

Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

[0029] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: an internal mechanism of a dynamically adjustable foam mold, including a foam mold 1, and two dynamically adjustable mechanisms 200 which are installed on both sides of the foam mold 1 and are mirror-symmetrical;

[0030] By the mutual cooperation of the dynamically adjustable mechanisms 200 on the foam mold 1, precise adjustment and optimization can be carried out according to different production requirements, enabling each part of the mold to be flexibly adjusted according to actual needs, so as to cope with foam boards of various shapes and sizes, thereby achieving all-round dynamic adjustment and ensuring that the produced foam boards fully meet the production requirements, which not only greatly improves production efficiency but also reduces production costs.

[0031] In this embodiment, the dynamically adjustable mechanism 200 is a structure for precise adjustment and optimization according to different production requirements.

[0032] Such as Figure 1 、 Figure 2 Figure 3 and Figure 4 As shown, the dynamically adjustable mechanism 200 includes a regulation box 201 fixedly installed on one side of the foam mold 1 and a drive box 202 fixedly installed on one side of the regulation box 201. A sliding support plate 204 is fixedly installed on the inner side wall of the regulation box 201 by bolts. A drive assembly is installed in the drive box 202, and a threaded push assembly connected to the drive assembly and slidably connected to the sliding support plate 204. An auxiliary movement assembly connected to the outside of the threaded push assembly and connected to the sliding support plate 204 and a pressing plate 207 connected to the threaded push assembly are provided.

[0033] It should be noted that the drive assembly includes a worm 2031, a handwheel 2032, and a worm gear 2033. One end of the worm 2031 is rotatably connected to the inner side wall of the drive box 202 through a bearing, and the opposite end penetrates through the drive box 202 and extends to the outside of the drive box 202 and is fixedly connected to the handwheel 2032. The worm 2031 meshes with the worm gear 2033 to stably drive the threaded push assembly to rotate.

[0034] It can be understood that the outer side of the worm 2031 is rotatably connected to the inside of the drive box 202 through a bearing so that when the handwheel 2032 is rotated, the worm 2031 can be stably driven to rotate, thereby driving the worm gear 2033 meshed with the worm 2031 to rotate and driving the threaded push assembly to rotate.

[0035] In addition, the screw driving assembly includes a screw rod 2051, a screw sleeve 2052, and a sliding support block 2053; one end of the screw rod 2051 is fixedly connected to the center of one side of the worm wheel 2033. The outer side of the screw rod 2051 is in threaded connection with the inner side of the screw sleeve 2052. The outer side of the screw sleeve 2052 is in sliding connection and fits with the inner side of the sliding support block 2053. One side of the sliding support block 2053 is fixedly installed on the inner side wall of the control box 201. This is to ensure that when the screw rod 2051 rotates, the screw sleeve 2052 can stably move inside the sliding support plate 204 and the sliding support block 2053 under the rotational thrust of the screw rod 2051, so as to drive the pressing plate 207 to move.

[0036] In this embodiment, the auxiliary moving assembly includes an annular connecting block 2061 and sliding rods 2062; the inner side of the annular connecting block 2061 is fixedly connected to the outer side of the screw sleeve 2052. The two ends of the sliding rods 2062 are respectively fixedly connected to the opposite sides of the control box 201 and the sliding support plate 204. The number of sliding rods 2062 is two and they are symmetrically distributed in a mirror image. The inner side of the annular connecting block 2061 is in sliding connection and fits with the outer side of the sliding rods 2062. This is to improve the moving stability of the screw sleeve 2052 while limiting the moving distance of the screw sleeve 2052.

[0037] It should also be noted that one end of the screw sleeve 2052 sequentially passes through the sliding support plate 204, the sliding support block 2053, the control box 201, and the foam mold 1 and extends into the foam mold 1, where it is fixedly connected to one side of the pressing plate 207 by bolts. This is to enable flexible adjustment according to actual needs, so as to deal with various foam boards of different shapes and sizes.

[0038] The working principle of the above embodiment is as follows:

[0039] In the initial state, each part of the foam mold 1 is in its default position. When adjustment is required, the operator rotates the handwheel 2032. The rotation of the handwheel 2032 drives the worm 2031 to rotate within the drive box 202. The worm 2031 meshes with the worm gear 2033. The rotation of the worm 2031 causes the worm gear 2033 to start rotating. A threaded rod 2051 is fixedly connected to the center of rotation of the worm gear 2033. Therefore, the threaded rod 2051 also rotates accordingly. The inner side of the threaded sleeve 2052 is threadedly connected to the threaded rod 2051. When the threaded rod 2051 rotates, due to the effect of the thread, the threaded sleeve 2052 will move along the axial direction of the threaded rod 2051. To ensure the stable movement of the threaded sleeve 2052, the inner side of the sliding support block 2053 is slidably connected to and in contact with the outer side of the threaded sleeve 2052. At the same time, the sliding support plate 204 also provides additional support and guidance for the threaded sleeve 2052. The annular connection block 2061 in the auxiliary moving component is fixed to the outer side of the threaded sleeve 2052, and the inner side of the annular connection block 2061 is slidably connected to and in contact with the outer side of the sliding rod 2062. In this way, the annular connection block 2061 can slide freely on the sliding rod 2062, thereby further improving the stability of the movement of the threaded sleeve 2052. As the threaded sleeve 2052 moves, one end of it will sequentially penetrate through the sliding support plate 204, the sliding support block 2053, the control box 201, and the foam mold 1, and finally be fixedly connected to the pressure plate 207 inside the foam mold 1 by bolts. Therefore, when the threaded sleeve 2052 moves, it will drive the pressure plate 207 to move correspondingly within the foam mold 1. By precisely controlling the rotation angle and direction of the handwheel 2032, fine adjustment of the position of the pressure plate 207 can be achieved, so that each part of the foam mold 1 can be flexibly adjusted according to actual needs.

[0040] Compared with the prior art: The internal mechanism of this dynamically adjustable foam mold can be precisely adjusted and optimized according to different production requirements through the mutual cooperation of the dynamically adjustable mechanism 200 on the foam mold 1, enabling each part of the mold to be flexibly adjusted according to actual needs, so as to cope with foam boards of various shapes and sizes, thereby achieving full - range dynamic adjustment and ensuring that the produced foam boards fully meet the production requirements. This not only greatly improves production efficiency but also reduces production costs, solving the problems of the fixed structure, cumbersome operation, and inconvenient full - range dynamic adjustment of existing foam molds.

[0041] It should be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or apparatus comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or apparatus. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or apparatus comprising said element.

[0042] Although embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
