Description

Technical Field

[0001] The present invention relates to the technical field of molds, and in particular to a molding device of a mold. Background Art

[0002] In today's industrial manufacturing landscape, molds are essential tools for forming a wide variety of products. Their production efficiency and product quality are directly linked to the development of numerous industries. Mold production line technology continues to evolve to meet market demand for diverse, high-quality mold products. However, existing mold production lines still face significant technical bottlenecks in several key areas, limiting improvements in production efficiency and the expansion of product offerings.

[0003] In the mold-forming process, powder addition is a crucial initial step, directly determining key characteristics of the final molded product, such as shape, density, and performance. However, current mold production lines suffer from serious deficiencies in powder control. Most existing powder addition methods lack an adjustment mechanism, making it impossible to flexibly and precisely control the amount of powder added based on varying product specifications and production requirements. This results in production lines operating according to fixed powder addition parameters, resulting in a monotonous range of mold products and making it difficult to meet market demand for more diverse mold products.

[0004] In addition, the hot pressing and demolding steps in the mold forming process, as key process steps that determine the final quality and production efficiency of the mold, currently have obvious separation problems in actual production. In the traditional production line layout, the hot pressing process and the demolding process are usually set up in different work areas and equipped with independent equipment. After the mold is hot pressed, it needs to be moved from the hot pressing equipment to the demolding equipment with the help of a conveying system for demolding. In this process, the movement of the mold not only increases the length of the production line, but also leads to a significant increase in the floor space occupied by the entire production process, resulting in low space utilization in the production workshop and increasing the company's site costs.

[0005] Therefore, the present application has developed a molding device for a mold to solve the problems existing in the prior art. Summary of the Invention

[0020] The present invention will be described in further detail below with reference to specific embodiments: like Figure 1 As shown, a molding device of a mold includes a carrying plate 1, a preheating device 6 and a conveying mechanism 7; wherein, a powder filling machine 2, an implanting machine 3 and a demolding hot press 4 are provided along the moving direction of the mold, and the demolding hot press 4 includes a hot press 41 and a demolding device 42.

[0021] The carrier plate 1 provides support and installation platform for the entire device. The preheating device 6 is installed on the carrier plate 1, which is used to preheat the mold so that the mold reaches a certain temperature state first. In the subsequent hot pressing process, the time required for hot pressing can be greatly reduced. The mold is moved to the preheating device 6 or the hot press 41 through the conveying mechanism 7. The hot press 41 is arranged at one end of the preheating device 6. When the mold is preheated and moved to the hot press 41, the hot press 41 performs a hot pressing molding process on the mold to form the material in the mold into the desired shape. The mold is then moved to the conveying mechanism 7 through the conveying mechanism 7, and the mold at the outlet of the hot press 41 with a height difference is moved to the entrance of the demolding device 42 through the conveying mechanism 7. Finally, the demolding device 42 is used to separate the mold that has completed hot pressing molding from the product to realize the removal of the product from the mold.

[0022] In actual application, two types of products can be produced. One of them is: along the moving direction of the mold, a powder filling machine 2, an implanting machine 3, a powder filling machine 2, and a demoulding hot press 4 are arranged in sequence; the powder filling machine 2 is used to fill the mold with powder to form a first layer of powder, and then the implanting machine 3 is used to install the coil on the first layer, and then the second powder is added to form a three-layer structure with two layers and one coil layer, and finally enters the demoulding hot press 4 for molding; Second: along the moving direction of the mold, there are powder filling machine 2, implanting machine 3, powder filling machine 2, implanting machine 3, powder filling machine 2, and demolding hot press 4. The mold passes through the corresponding devices in sequence and finally forms a five-layer structure with three powder layers and two coil layers.

[0023] In this embodiment, the conveying mechanism 7 includes a moving device 71 and a transfer mechanism 72. The moving device 71 is used to move the mold on the conveyor belt 5 to the preheating device 6, and also move the preheated mold to the hot press 41, and move the hot pressing mold out of the hot press 41. Specifically, the moving device 71 includes a loading mechanism 711 and a unloading mechanism 712. The moving directions of the loading mechanism 711 and the unloading mechanism 712 are both arranged along the length direction of the preheating device 6, and the moving range of the loading mechanism 711 spans the conveyor belt 5, thereby meeting the need to move the mold from the conveyor belt 5 to the preheating device 6, and the unloading mechanism 712 can drive the mold to accurately stay at any specified position along the moving direction to ensure the orderly flow of the mold between various processes.

[0024] As shown in the figure, the demoulding device 42 and the hot press 41 are connected by a transfer device, and there is no need to move the mold out of the hot press 41 and then move to the next process to complete the demoulding, which reduces the complexity of the process. In addition, since the mold enters the demoulding device 42 after completing the hot pressing, instead of the traditional multiple batches entering the demoulding device 42 in batches along the conveyor belt 5, when the product has defects or damage after demoulding, the traditional method cannot determine which batch has the problem among the many molds, which increases the difficulty of troubleshooting. In this application, products from different batches are moved to the demoulding device 42 of the batch, and it is easy to determine which process has the problem, so as to carry out maintenance.

[0025] In actual application, as shown in the figure, in order to improve production efficiency and production capacity, two hot pressing modules are set in the hot press 41, and both are installed inside the hot press 41. Compared with the traditional hot press 41, which has only one hot pressing module inside, the present application provides two hot pressing modules in the hot press 41, utilizing the extra space inside the hot press 41 without increasing the volume of the hot press 41, and each hot pressing module is equipped with a complete set of preheating, demolding, conveying, transfer and reflux devices 722, forming two relatively independent and mutually coordinated production paths, thereby significantly improving the overall production efficiency of the hot pressing and demolding all-in-one machine and meeting the needs of large-scale production.

[0026] In this embodiment, as shown in the figure, the transfer mechanism 72 includes a lifting device 721 and a reflux device 722. A through hole 61 is opened on the preheating device 6, and the lifting device 721 is arranged inside the through hole 61; when the mold is in the conveying stage, the upper surface of the lifting device 721 and the surface of the preheating device 6 are at the same horizontal height, that is, the two are flush, so as to ensure that the mold can be smoothly and smoothly conveyed to the preheating device 6 or the hot press 41; when the mold completes hot pressing in the preheating device 6 and needs to be transferred, the unloading mechanism 712 moves the mold to the lifting device 721, and the lifting device 721 moves downward. After moving into place, its upper surface is at the same horizontal height as the upper surface of the reflux device 722, that is, the two are flush, thereby realizing a smooth transition and transportation of the mold from the preheating device 6 to the reflux device 722, and ensuring the continuity and stability of the mold flow between various processes in the all-in-one machine.

[0027] Specifically, as shown in the figure, the reflux device 722 includes a slide 7221, a first drive device 7222 and a second drive device 7223. The laying direction of the slide 7221 is the same as the direction of the conveyor belt 5, and extends to the entrance of the demolding device 42, providing a clear path guide for the movement of the mold in the reflux device 722. The first drive device 7222 is installed at one end of the slide 7221 away from the demolding device 42, and its movement direction is consistent with the movement direction of the mold on the preheating device 6. The second drive device 7223 is installed on one side of the slide 7221 to drive the mold to move along the laying direction of the slide 7221. When the mold completes hot pressing and is moved out through the lifting device 721, the first drive device 7222 is started, and its drive end pushes the mold from the lifting device 721 smoothly to the slide 7221, completing the initial transfer of the mold from the lifting device 721 to the slide 7221. After the first drive device 7222 transfers the mold to the slide 7221, the second drive device 7223 is started, driving the mold to slide in the slide 7221, and finally accurately transporting the mold to the position of the demolding device 42, realizing the automated connection of the mold from hot pressing molding to demolding processes.

[0028] Furthermore, a plurality of cooling pipes 7224 are installed on the reflux device 722. The plurality of cooling pipes 7224 are neatly arranged in an array in the moving direction of the mold. One end of the cooling pipe 7224 is connected to a cold source, and the other end, i.e., the outlet, is vertically directed toward the upper surface of the mold, thereby quickly taking away the heat accumulated in the mold during the hot pressing process, effectively reducing the temperature of the mold, and facilitating subsequent demolding.

[0029] As shown in the figure, in order to prevent the product from falling directly after demolding and causing product bumps, which affects product quality, the demolding device 42 includes a demolding hole and a receiving box. The demolding hole is set at a designated position for the demolding operation, and the mold moves to this position to wait for demolding. The demolding hole also provides space for the product to fall, and the receiving box is set directly below the demolding hole, and its position precisely corresponds to the demolding hole. When the mold completes the demolding operation at the demolding hole, the product will fall directly into the receiving box directly below after it is ejected from the mold, thereby realizing effective reception and collection of the product, avoiding direct falling of the product and causing bumps to the product due to excessive height difference.

[0030] In this embodiment, the powder filling machine 2 further includes a powder feeding assembly 24 , and the powder filling box 21 , the powder quantity control unit 22 , and the powder feeding assembly 24 are sequentially arranged along the powder moving direction.

[0031] The main function of the powder filling box 21 is to accommodate the powder to be processed. A first through hole 25 is provided at the bottom thereof. The powder can flow out of the powder filling box 21 through the first through hole 25, providing a source of powder for subsequent quantitative and powder feeding steps. A second through hole 26 is provided inside the powder quantity control portion 22. One end of the quantitative column 23 is mounted on the cylinder, and the other end extends into the second through hole 26 of the powder quantity control portion 22. The quantitative column 23 is driven by the cylinder to move, and the distance between the top surface of the quantitative column 23 and the top surface of the powder quantity control portion 22 can be accurately controlled. This distance directly determines the capacity of the powder that can be accommodated in the second through hole 26, thereby achieving control of the powder capacity. The driving component 27 can control the powder quantity control portion 22 to move in a first direction. When the powder quantity control portion 22 moves to a specific position, the first through hole 25 at the bottom of the powder filling box 21 is connected to the second through hole 26 inside the powder quantity control portion 22. At this time, the powder can flow from the first through hole 25 to the second through hole 26; when the powder quantity control portion 22 moves to other positions, the first through hole 25 and the second through hole 26 are misaligned and separated, thereby preventing the powder from continuing to flow into the second through hole 26, thereby completing the quantitative control of the powder. The powder feeding assembly 24 includes a powder feeding hopper 241 and a control unit 242, and the powder feeding hopper 241 is provided with a powder feeding chamber 243. The feeding assembly can reciprocate along a second direction perpendicular to the first direction through the action of the cylinder. During the reciprocating motion, the feeding hopper will receive the powder processed by the powder filling box 21 and the quantitative assembly, and accurately move the powder into the mold to complete the powder feeding process of the entire powder filling press.

[0032] Specifically, the first direction is the driving direction of the first driving portion 271 , and the second direction is perpendicular to the first direction and is a direction away from the powder feeding box.

[0033] As shown in the figure, the powder amount control part 22 includes a powder amount control plate 221 and a transition plate 222 arranged in sequence along the powder movement direction. The second through hole 26 includes a quantitative hole 223 opened on the powder amount control plate 221 and a transition hole 224 opened on the transition plate 222. The driving component 27 includes a first driving part 271 and a second driving part 272 located in the first direction and arranged on both sides of the powder filling box 21. The driving end of the first driving part 271 acts on the powder filling box 21 and can drive the powder filling box 21 to move along the first direction; the driving end of the second driving part 272 acts on the powder amount control plate 221 to drive the powder filling box 21 and the powder amount control plate 221 to move together in the opposite direction of the first direction. In the initial state, the first through hole 25 at the bottom of the powder filling box 21 and the quantitative hole 223 on the powder amount control plate 221 are in a staggered state and are not connected. At the same time, one end of the quantitative column 23 passes through the transition hole 224 on the transition plate 222 and extends to the inside of the quantitative hole 223 of the powder amount control plate 221.

[0034] Its working principle is as follows: when it is necessary to adjust the powder feeding amount according to the requirements of different products, the operator will first adjust the height of the quantitative column 23. By changing the height of the quantitative column 23, the distance between the top surface of the quantitative column 23 and the top surface of the powder quantity control plate 221 can be accurately controlled, and then the powder capacity that can be accommodated in the quantitative hole 223 is adjusted, that is, the amount of powder to be fed; after adjusting the height of the quantitative column 23, the powder feeding process begins. First, the first driving unit 271 starts working, driving the powder filling box 21 to move in the first direction. As the powder filling box 21 moves, the first through hole 25 at its bottom gradually aligns with and connects with the quantitative hole 223 on the powder quantity control plate 221. At this time, the powder in the powder filling box 21 will flow into the quantitative hole 223 through the first through hole 25 until the quantitative hole 223 is filled with powder. The first driving unit 271 drives the powder filling box 21 back to its initial position again.

[0035] Subsequently, the metering column 23 descends until its top surface is level with the bottom surface of the powder quantity control plate 221. The second drive unit 272 is activated, driving the powder quantity control plate 221 and the powder filling box 21 to move in a direction opposite to the first direction. During this movement, the previously misaligned metering holes 223 gradually connect with the transition hole 224. At this point, the transition hole 224 corresponds to the position of the powder feeding chamber 243 in the powder feeding assembly 24. The powder filled in the metering hole 223 is smoothly transferred through the transition hole 224 to the powder feeding chamber 243, preparing for the subsequent feeding of the powder into the mold.

[0036] Furthermore, the first through hole 25 at the bottom of the powder filling box 21, the quantitative hole 223 on the powder quantity control plate 221, and the transition hole 224 on the transition plate 222 are all arranged in an array. When the first through hole 25 and the quantitative hole 223 are projected onto the transition hole 224 from a direction perpendicular to the plane where the transition hole 224 is located, the projection of the first through hole 25 and the projection of the quantitative hole 223 can correspond one-to-one with the transition hole 224, that is, the transition hole 224 needs to provide a moving channel for the quantitative column 23 and a moving channel for the powder to ensure the completion of the determined powder feeding.

[0037] As shown in the figure, the powder feeding hopper 241 is arranged along the second direction and away from the powder filling box 21. A powder feeding cavity 243 corresponding to the quantitative hole 223 is opened on the powder feeding hopper 241. Each powder feeding cavity 243 corresponds to a quantitative hole 223, ensuring that the powder transferred from the quantitative hole 223 can accurately fall into the corresponding powder feeding cavity 243. In order to achieve the precise flow of powder from the powder feeding cavity 243 into the cavity of the mold, a control unit 242 is set on the powder feeding hopper 241 for locating the position of the powder feeding cavity 243 to ensure that when the powder feeding cavity 243 corresponds to the cavity position of the mold, the powder can smoothly flow into the mold.

[0038] Specifically, the control unit 242 includes a mounting groove 2421, a limiting plate 2422, an elastic element 2423 and a limiting block 2424. The mounting groove 2421 is provided inside the powder feeding hopper 241 and close to the powder filling box 21, providing a mounting space for the limiting block 2424. The limiting plate 2422 is slidably provided on the bottom surface of the powder feeding hopper 241 and is provided with a limiting hole 2425 corresponding to the powder feeding chamber 243. When the limiting hole 2425 is aligned with the powder feeding chamber 243, the powder is fed into the powder feeding hopper 241. The material can flow out from the powder feeding chamber 243 through the limiting hole 2425. The limiting block 2424 is located in the mounting groove 2421 and is fixedly connected to one end of the limiting plate 2422, forming a structure protruding toward the mold. One end of the elastic element 2423 is connected to the limiting block 2424, and the other end is connected to the side wall of the mounting groove 2421, providing elastic support and reset function for the limiting block 2424 and the limiting plate 2422. Specifically, the elastic element 2423 is a spring.

[0039] During actual operation, when the powder feeding hopper 241 moves toward the mold, the limit block 2424 will first come into contact with the mold. As the powder feeding hopper 241 continues to move, the limit block 2424 is blocked by the mold and cannot move forward, while the powder feeding hopper 241 will slide relative to the limit plate 2422. During this process, the spring is compressed, resulting in elastic deformation. At the same time, the originally misaligned powder feeding chamber 243 and the limit hole 2425 gradually connect. When the powder feeding chamber 243 and the limit hole 2425 are fully connected, the powder in the powder feeding chamber 243 can flow smoothly into the cavity of the mold through the limit hole 2425, completing the precise powder feeding operation. When the powder feeding is completed, the elastic restoring force of the spring will reset the limit block 2424 and the limit plate 2422, preparing for the next powder feeding.
