Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, and in particular to a molding mold for producing microporous refractory products. Background Technology
[0002] Microporous refractory products are widely used in high-temperature industries such as metallurgy, ceramics, and chemicals due to their excellent high-temperature resistance, low thermal conductivity, and good thermal shock resistance. Their core performance depends on the uniform distribution and precise molding of the internal microporous structure. As a key device for forming microporous structures, the rationality of the mold design directly determines the porosity, mechanical strength, and stability of the product. Therefore, developing efficient and high-precision molding dies is of great significance for improving the quality and production efficiency of microporous refractory products.
[0003] In the existing technology, the molding molds for microporous refractory products mostly adopt a split template structure. The template is fixed and closed by bolts or simple buckles. During the assembly process, the operator needs to manually adjust the position of the template and rely on experience to ensure the alignment accuracy. Then, multiple sets of fasteners are used to lock it in sequence. In addition, some molds use slide rail guides or pin positioning methods to assist in alignment. However, these structures usually rely on complex external adjustment devices and are prone to positioning deviation due to wear after repeated use.
[0004] However, the above-mentioned technologies have significant problems in practical applications. When the template needs to be replaced, the alignment process is time-consuming and the accuracy is difficult to guarantee. Especially in mass production, manual adjustment is prone to introducing deviations, which can lead to misalignment after the template is closed. Such alignment deviations can directly cause uneven distribution of microporous structures or damage to the pore walls, thereby affecting the heat insulation performance and mechanical strength of refractory products and significantly reducing the finished product qualification rate. How to achieve rapid and accurate alignment and stable locking of the template has become a key problem restricting the improvement of the molding quality of microporous refractory products. Utility Model Content

[0013] Furthermore, the connecting plate is provided with a plurality of balls and a plurality of springs, one end of each spring being fixedly connected to the inside of the connecting plate and the other end of each spring being fixedly connected to the outer wall of the balls.
[0014] Furthermore, one of the templates has a protruding post fixedly connected inside, and the other template has a through-hole groove inside, with the protruding post disposed inside the groove.
[0015] This utility model has the following beneficial effects:
[0016] 1. In this utility model, the connecting component cooperates with the rotating block through the rotating shaft.

[0017] 2. In this utility model, the rotating handle of the demolding component causes helical gear one and helical gear two to mesh and drive the threaded rod to drive the slider to move linearly.

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] Reference Figures 1-3This utility model provides an embodiment of a molding die for producing microporous refractory products, comprising two connecting plates 1, each with a template 2 on one side. The symmetrical design of the connecting plates 1 and template 2 ensures the stability and uniform force distribution when the die is closed. Connecting components and demolding components are provided inside the connecting plates 1. The connecting components include a rotating shaft 6, which is located inside both the connecting plates 1 and the template 2. A torsion piece 7 is fixedly connected to one end of the rotating shaft 6, providing a manual operation interface for quick adjustment of the shaft 6's position. A locking block 8 is fixedly connected to the outer wall of the rotating shaft 6. A rotating block 9 is located inside the connecting plates 1, with a through-hole 10. The rotating shaft 6 is located inside the through-hole 10. The cooperation between the through-hole 10 and the locking block 8 achieves mechanical self-locking. The function ensures that the template 2 will not loosen accidentally after positioning. The outer wall of the rotating block 9 is fixedly connected to the connecting rod 11, which serves as a rotation drive component and simplifies the operation process. Multiple balls 13 and multiple springs 12 are set inside the connecting plate 1. One end of the spring 12 is fixedly connected inside the connecting plate 1, and the other end of the spring 12 is fixedly connected to the outer wall of the ball 13. The ball 13 and the spring 12 form an elastic positioning mechanism. After the connecting rod 11 rotates to the position through the ball 13, the spring 12 returns to its original position. The ball 13 provides damping positioning to prevent rebound. A protruding post 3 is fixedly connected inside one template 2, and a through hole 4 is opened inside the other template 2. The protruding post 3 is set inside the hole 4. The precise cooperation between the protruding post 3 and the hole 4 realizes the pre-positioning function of the template 2, significantly improving the alignment accuracy and avoiding the forming deviation of the microporous structure.
[0027] Reference Figures 1-5 The demolding assembly includes a threaded rod 18, the outer wall of which is rotatably connected to the inside of the connecting plate 1. A slider 19 is threadedly connected to the outer wall of the threaded rod 18, and a push block 5 is fixedly connected to one side of the outer wall of the slider 19. The threaded transmission structure converts rotational motion into linear thrust, ensuring a smooth and controllable demolding process. A drive assembly is provided inside the connecting plate 1, including a helical gear 17. The helical gear 17 is located inside the connecting plate 1, and its inner wall is fixedly connected to the outer wall of the threaded rod 18. The helical gear transmission has a self-locking characteristic, which can prevent the mechanism from accidentally retracting during the demolding process. A helical gear is also provided inside the connecting plate 1. 16. Helical gear 16 and helical gear 2 17 mesh together, using a 90-degree transmission helical gear set, which optimizes the layout of the operating space. A drive shaft 15 is fixedly connected to one side of the outer wall of helical gear 16. A handle 14 is fixedly connected to one end of the drive shaft 15. The handle 14 is easy to operate and can accurately control the demolding force. A spring 20 is sleeved on the outer wall of the threaded rod 18. One end of the spring 20 is fixedly connected to the inside of the connecting plate 1, and the other end of the spring 20 is fixedly connected to one side of the outer wall of the slider 19. After demolding, the spring 20 automatically resets the slider 19, while buffering the demolding impact force and protecting the structural integrity of the molded product.
[0028] Working Principle: When using this type of molding die for producing microporous refractory products, firstly, two templates 2 are assembled using a connecting assembly. Then, the operator rotates the connecting rod 11, causing the rotating block 9 to rotate, so that the irregular hole 10 engages with the locking block 8 for positioning. Spring 12, through the ball bearing 13, locks the connecting rod 11, preventing it from rotating and ensuring that the templates 2 are quickly and accurately connected and locked, avoiding microporous structure defects caused by misalignment. Subsequently, refractory material is injected into the closed mold cavity, and uniform pressure is applied to the mold to ensure that the material fully fills the microporous structure. After molding, the demolding assembly is used to demold the product. By rotating the handle 14, the transmission shaft 15 is driven, causing the helical gear 16 and helical gear 27 to mesh and rotate, thereby driving the threaded rod 18 to rotate and compressing the spring 20. The rotation of the threaded rod 18 causes the slider 19 to move axially, pushing the push block 5 to apply a uniform pushing force to the molded product, completely ejecting the molded product. After demolding, the spring 20 assists the slider 19 and handle 14 to return to their original positions.
[0029] 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.
