Description

Technical Field

[0001] This utility model relates to the field of helmet technology, and in particular to a mold fixing structure for a helmet foam molding machine. Background Technology

[0002] With the increasing awareness of traffic safety, helmets, as a key protective device for riders' head safety, have received much attention in terms of quality and manufacturing process. With the continuous growth of motorcycle and electric bicycle ownership, the market demand for helmets is enormous. According to relevant data, my country has nearly 100 million motorcycles and more than 300 million electric bicycles. In motorcycle and electric bicycle-related traffic accidents, the importance of helmets is self-evident.

[0003] In helmet production, foam molding is a crucial step, and the mold fixing structure plays a decisive role in the molding quality. Traditional helmet foam molding machine mold fixing structures have many problems. On the one hand, they lack stability. During the molding process, the mold is easily affected by factors such as pressure and vibration, causing displacement and shaking. For example, some structures that use simple bolts to fix the mold are prone to loosening under long-term, high-intensity production operations, causing the mold position to shift. This not only leads to deviations in the size and irregular shape of the produced helmet, but also causes uneven thickness in different parts of the helmet, greatly affecting the helmet's protective performance and making it difficult to meet the strict requirements of the "new national standard" in terms of absorbing impact energy and penetration resistance.

[0004] Traditional fixed structures are not user-friendly. When different mold sizes need to be changed to meet diverse production needs, the cumbersome disassembly and installation process consumes a lot of time and manpower. For example, some structures require the sequential removal of multiple complex connectors and positioning pins, and repeated adjustments and positioning are required during reinstallation, resulting in low production efficiency. This makes it impossible to meet the rapidly changing market demands, increases production costs, and reduces the company's competitiveness in the market. Therefore, a mold fixing structure for a helmet foam molding machine is proposed. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides a mold fixing structure for a helmet product foam molding machine, aiming to improve the problem that some devices in the prior art cannot fix the mold.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A mold fixing structure for a helmet foam molding machine includes a support fixing plate. A fixing mechanism is fixedly connected to the outside of the support fixing plate, and a molding mechanism is fixedly connected to the outside of the support fixing plate. The fixing mechanism includes a driving component for driving. A support fixing block is fixedly connected to the outside of the driving component. The outside of the driving component is fixedly connected to the inside of the support fixing plate, and the outside of the support fixing block is fixedly connected to the inside of the support fixing plate. A connecting sliding plate is fixedly connected to the outside of the driving component. A connecting rotating rod is rotatably connected to the outside of the connecting sliding plate. A rotating connecting block is rotatably connected to the outside of the connecting rotating rod, i.e., the end away from the connecting sliding plate. A connecting sliding plate is slidably connected to the inside of the connecting sliding plate. As a further description of the above technical solution: The forming mechanism includes a support connecting rod, with connecting and fixing rings fixedly connected to both outer ends of the support connecting rod, and a sliding telescopic rod fixedly connected to the outside of the connecting and fixing rings; As a further description of the above technical solution: The outer side of the connecting sliding plate is slidably connected to the outer side of the supporting fixed plate, and the inner side of the connecting sliding plate is slidably connected to a supporting rail, the bottom of which is fixedly connected to the inner side of the supporting fixed plate. As a further description of the above technical solution: The external rotating rod is rotatably connected to the outside of the support fixing plate, and the external rotating connecting block is rotatably connected to the outside of the support fixing plate. As a further description of the above technical solution: The drive assembly includes a telescopic cylinder, the drive end of which is fixedly connected to a connecting telescopic rod, and the outside of the telescopic cylinder is fixedly connected to the outside of the support block. As a further description of the above technical solution: The external connection of the telescopic rod is fixedly connected to the outside of the connecting sliding plate; As a further description of the above technical solution: The supporting connecting rod is externally fixedly connected to a connecting sliding column, and the connecting sliding column is externally fixedly connected to a connecting fixing block; As a further description of the above technical solution: A connecting compression plate is fixedly connected to the bottom of the connecting sliding column.

The outer side of the connecting sliding column is slidably connected to the inner side of the supporting fixed plate. A rotating connecting rod is rotatably connected to the outer side of the supporting connecting rod.

[0007] This utility model has the following beneficial effects: 1. In this utility model, the operation of the telescopic cylinder drives the sliding of the connecting telescopic rod, which in turn drives the moving of the connecting sliding plate. Under the stable support of the support rail, the connecting sliding plate drives the connecting rotating rod and the rotating connecting block to rotate synchronously, realizing the rapid fixing of the mold, shortening the mold fixing time, improving production efficiency, and ensuring the stable and reliable fixing process by the linkage of various components, reducing the risk of mold displacement. The modular structure facilitates maintenance and replacement, reduces equipment operating costs, adapts to various mold specifications, enhances equipment versatility, and lays a solid foundation for the rapid molding of foam for helmet products.

[0008] 2. In this utility model, rotating the connecting rod causes it to exert a squeezing effect on the connecting sliding column and the sliding telescopic rod. With the connecting fixing ring fixing the position of the connecting sliding column, the connecting extrusion plate is driven to slide downward, realizing the extrusion molding of the material in the mold. It has high stability and can effectively avoid molding failure caused by power system failure. It is simple to operate, reducing the technical threshold for operators. The connecting fixing ring ensures that the relative positions of each component are fixed, making the extrusion process controllable. The structure is compact, occupies little space, and facilitates the layout and installation of equipment, providing a guarantee for the efficient production of helmet foam products.

[0011] 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.

[0012] Reference Figure 1 , Figure 4 This utility model provides an embodiment of a mold fixing structure for a helmet foam molding machine, including a support fixing plate 1, which serves as the basic load-bearing component of the entire mold fixing structure, providing an installation support platform for the fixing mechanism 2 and the molding mechanism 3, ensuring that each component remains stable during operation and withstands various forces during mold fixing and molding processes. The support fixing plate 1 is externally fixedly connected to the fixing mechanism 2, and the molding mechanism 3 is also externally fixedly connected to the support fixing plate 1. The fixing mechanism 2 includes a drive assembly 21 for driving, providing a power source for mold fixing, and connecting the sliding mechanism via the drive assembly. The plate 24 moves to clamp and fix the mold. The drive assembly 21 is externally fixedly connected to the support fixing block 22, which fixes and supports the drive assembly 21 and ensures the stability of the telescopic cylinder 211 during operation. The drive assembly 21 is externally fixedly connected to the inner side of the support fixing plate 1, and the support fixing block 22 is externally fixedly connected to the inner side of the support fixing plate 1. The drive assembly 21 is externally fixedly connected to the connecting sliding plate 24, which serves as an intermediate component for power transmission, converting the linear motion of the drive assembly 21 into the rotational motion of the connecting rotating rod 25, and allowing it to slide smoothly under the support of the support rail 23. A connecting rotating rod 25 is rotatably connected to the outside of the connecting sliding plate 24, which converts the linear motion of the connecting sliding plate 24 into the rotation of the rotating connecting block 26, thereby realizing the clamping and fixing action of the mold. The rotating connecting block 26 is rotatably connected to the outside of the connecting rotating rod 25, that is, the end away from the connecting sliding plate 24, and directly contacts the mold. The clamping and fixing of the mold is realized through the rotational movement, ensuring that the mold remains stable during the molding process and does not shift. The connecting sliding plate 24 is slidably connected inside the connecting sliding plate 24, and the connecting sliding plate 24 is slidably connected to the outside of the supporting fixing plate 1. The connecting sliding plate 24 is internally slidably connected to a support rail 23, which provides sliding guidance and support for the connecting sliding plate 24, ensuring that the connecting sliding plate 24 slides smoothly in the horizontal direction. The bottom of the support rail 23 is fixedly connected to the inside of the support fixing plate 1. The external part of the connecting rotating rod 25 is rotatably connected to the outside of the support fixing plate 1. The external part of the rotating connecting block 26 is rotatably connected to the outside of the support fixing plate 1. The driving assembly 21 includes a telescopic cylinder 211. The driving end of the telescopic cylinder 211 is fixedly connected to a connecting telescopic rod 212. The external part of the telescopic cylinder 211 is fixedly connected to the outside of the support fixing block 22. The external part of the connecting telescopic rod 212 is fixedly connected to the outside of the connecting sliding plate 24.

[0013] Reference Figures 1 to 3 The molding mechanism 3 includes a support connecting rod 31, which serves as the main support component of the molding mechanism 3, connects and fixes other components, and provides an installation base for connecting sliding columns 35 and rotating connecting rods 34. The outer ends of the support connecting rod 31 are fixedly connected to connecting fixing rings 32, which fix and position the sliding telescopic rod 33 and the connecting sliding column 35, ensuring that they maintain the correct positional relationship during movement and preventing swaying or displacement. The outer side of the connecting fixing ring 32 is fixedly connected to the sliding telescopic rod 33, which plays a buffering and guiding role during the molding process. Together with the connecting sliding column 35, it enables the connecting extrusion plate 37 to move up and down smoothly, while absorbing a certain impact force during the extrusion process to protect the equipment and mold. The connecting rod 31 is externally fixedly connected to a connecting sliding column 35, which converts the rotational motion of the rotating connecting rod 34 into linear motion, driving the connecting extrusion plate 37 to move up and down. At the same time, under the positioning of the connecting fixing ring 32, the accuracy and stability of the motion are ensured. The connecting sliding column 35 is externally fixedly connected to a connecting fixing block 36, which strengthens the connection strength between the connecting sliding column 35 and the connecting extrusion plate 37, ensuring that during the extrusion molding process, the bottom of the connecting sliding column 35 is fixedly connected to the connecting extrusion plate 37, which directly contacts the foam material in the mold. By moving downward, pressure is applied to the foam material, causing it to be formed into the required helmet product shape in the mold. The external sliding connection of the connecting extrusion plate 37 is slidably connected to the inner side of the supporting fixing plate 1, the external sliding connection of the connecting sliding column 35 is slidably connected to the inner side of the supporting fixing plate 1, and the external rotating connection of the supporting connecting rod 31 is rotatably connected to the rotating connecting rod 34, which converts the rotational motion into the linear downward motion of the connecting sliding column 35 and the connecting extrusion plate 37.

[0014] Working principle: When it is necessary to fix the mold, the operation of the telescopic cylinder 211 drives the sliding of the connecting telescopic rod 212, which in turn drives the sliding of the connecting sliding plate 24, thereby driving the rotation of the connecting rotating rod 25 and the rotating connecting block 26. At the same time, the support rail 23 provides support for the movement of the connecting sliding plate 24, thereby achieving the effect of fixing the mold and thus achieving the effect of rapid molding.

[0015] When molding is required, the rotating connecting rod 34 is rotated, thereby pressing the connecting sliding column 35 and the sliding telescopic rod 33, which in turn causes the connecting extrusion plate 37 to slide downward. At the same time, the connecting fixing ring 32 is used to fix the position of the connecting fixing ring 32 and the connecting sliding column 35, thereby achieving the effect of extrusion molding.

[0016] 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.
