Description

Technical Field

[0001] This utility model belongs to the field of mold forming technology, specifically relating to a multi-process forming mold. Background Technology

[0002] Product molding refers to the process of transforming raw materials into products with specific shapes and dimensions. By selecting appropriate molding methods and creating molds, products can achieve the desired shape and dimensional accuracy required for production, thereby improving their aesthetics and overall quality. The process from raw materials to finished product involves multiple processing steps. Current technologies often employ a multi-mold arrangement across an entire production line. This molding method requires the completion of each step before proceeding to the next, resulting in low molding efficiency. Furthermore, during the current process, the conveyor belt is prone to swaying, and the transport from one step to the next is susceptible to jamming, affecting both molding quality and efficiency. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a multi-process molding mold, which solves the problems of low molding efficiency and low molding quality in the prior art.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] A multi-stage molding die is disclosed, comprising an upper die mechanism, a lower die mechanism, and a guide frame. The upper die mechanism is positioned above the lower die mechanism, and a conveyor belt is provided between the upper die mechanism and the lower die mechanism. The guide frame is located on one side of the lower die mechanism and is used to transfer the material to be molded to the conveyor belt. The upper die mechanism is provided with an ejector mechanism and multiple upper die processes arranged sequentially according to the molding sequence along the conveyor belt. The ejector mechanism is positioned between two upper die processes. The lower die mechanism is provided with a floating mechanism and multiple lower die processes corresponding to the multiple upper die processes. The floating mechanism is positioned between two lower die processes.

[0006] In some embodiments, the upper mold mechanism includes a mold closing pressure component and a mold closing buffer component. The mold closing pressure component is disposed above the mold closing buffer component, and there is a buffer gap between the mold closing pressure component and the mold closing buffer component. The mold closing pressure component and the mold closing buffer component are connected by a guide component. When the upper mold mechanism closes the mold to the lower mold mechanism, the mold closing pressure component moves closer to the mold closing buffer component along the guiding direction of the guide component, and the buffer gap between the mold closing pressure component and the mold closing buffer component becomes smaller.

[0007] In some embodiments, the mold closing pressure assembly includes an upper pad, an upper clamping plate, and an upper mold base arranged sequentially from bottom to top in a direction away from the mold closing buffer assembly, and the upper pad, upper clamping plate, and upper mold base are detachably connected by bolts; the mold closing buffer assembly includes a stripper plate and a stop plate arranged sequentially from bottom to top in a direction away from the lower mold mechanism, and the stripper plate and the stop plate are detachably connected by bolts.

[0008] In some embodiments, the ejector mechanism includes an ejector pin and an ejector pin. One end of the ejector pin is connected to the mold closing pressure assembly, and the other end of the ejector pin is movably disposed within the ejector pin. The ejector pin moves up and down with the upper mold mechanism as it closes or opens the lower mold mechanism. One end of the ejector pin extends out of the bottom surface of the stripper plate. When the upper mold mechanism closes, the end of the ejector pin extending out of the ejector pin contacts the conveyor belt. When the upper mold mechanism opens, the end of the ejector pin retracts into the ejector pin.

[0009] In some embodiments, the lower mold mechanism includes a lower template, a lower pad, and a lower mold base arranged sequentially from top to bottom away from the upper mold mechanism. The lower template and the lower pad are bolted together, and the lower pad and the lower mold base are bolted together.

[0010] In some embodiments, the floating mechanism includes a floating rod, a floating cylinder, and a floating pin. One end of the floating rod is provided with a floating head, and the other end of the floating rod can move up and down inside the floating cylinder. When the floating rod moves up and down in the floating cylinder, it drives the conveyor belt to be pushed out or fall. The floating cylinder and the floating pin are threaded together so that the lower template and the lower pad are connected to each other.

[0011] In some embodiments, the guiding assembly includes a guide post, a first guide sleeve, and a second guide sleeve. The first guide sleeve is formed on the stripper plate, and the second guide sleeve is formed on the lower template. One end of the guide post is connected to the mold closing pressure assembly, and the other end of the guide post can slide within the first guide sleeve and the second guide sleeve.

[0012] In some embodiments, the upper mold process and the lower mold process constitute a forming process, which includes a pre-bending process, a bending process and a forming process arranged in sequence, wherein the pre-bending process, the bending process and the forming process operate synchronously for their respective target forming materials.

[0013] This utility model includes, but is not limited to, the following beneficial effects: (1) This solution integrates multiple processes into the same mold, reducing the conversion time in the production process and improving the overall production efficiency; (2) By setting up a guide frame, the material to be formed can be smoothly transferred to the conveyor belt, reducing the loss and waste of materials during the conveying process; (3) The buffer design between the mold closing pressure component and the mold closing buffer component enables the mold to effectively absorb the impact force during the mold closing process, improving the stability and service life of the mold; (4) The design of the ejector mechanism makes the conveyor belt stable in this position, realizing the positioning of the conveyor belt, so as to reduce the forming of the current process. The shaking during the process improves the molding stability, thereby improving the molding quality. After the current process is completed, the conveyor belt is separated from the ejector pin by the ejector mechanism, which facilitates the further transportation of the conveyor belt. Furthermore, the design of the ejector mechanism realizes automated ejection, reduces manual intervention, and improves the automation level and safety of production. (5) Through the design of the floating mechanism, the conveyor belt can be floated after molding, which improves the smoothness of conveying the conveyor belt. (6) The setting of the guide components (including guide pillars, first guide sleeve and second guide sleeve) makes the mold closing pressure component move smoothly during the mold closing process, reduces friction and wear, and extends the service life of the mold.

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0020] This application discloses a multi-process molding die, specifically, as follows: Figure 1 As shown, the multi-process molding die includes an upper mold mechanism 2, a lower mold mechanism 3, and a guide frame 1. The upper mold mechanism 2 is located above the lower mold mechanism 3. A conveyor belt is provided between the upper mold mechanism 2 and the lower mold mechanism 3. The guide frame 1 is located on one side of the lower mold mechanism 3. The guide frame 1 is used to transfer the material to be molded to the conveyor belt. The upper mold mechanism 2 is provided with an ejector mechanism 5 and multiple upper mold processes 4 arranged sequentially according to the molding sequence along the conveying direction of the conveyor belt. The ejector mechanism 5 is located between two upper mold processes 4. The lower mold mechanism 3 is provided with a floating mechanism 7 and multiple lower mold processes corresponding to the multiple upper mold processes 4. The floating mechanism 7 is located between two lower mold processes.

[0021] It is understandable that multiple upper die processes 4 and corresponding multiple lower die processes constitute a forming process. The forming process may include a pre-bending process, a bending process, and a forming process to form... Figure 2 The molded products shown may also include Figure 3 The process shown is punching-punching-punching-trimming-trimming-pre-bending-bending-idle step-forming-idle step-cutting. It is understandable that... Figure 2 and Figure 3 The process description provided is merely an illustrative example. Based on the principle of integrating multiple processes into a single mold in this application, different processes can be arranged according to molding requirements. It should be noted that the molding processes operate synchronously for their respective target molding materials. For example, based on... Figure 3 In the process shown, when there are two materials, A and B, to be formed, transported sequentially, material B is in the initial waiting position when material A is punched for the first time. When material A is punched for the second time, material B is punched for the first time simultaneously. When material A is punched for the third time, material B is punched for the second time simultaneously. When material A is trimmed for the first time, material B is punched for the third time simultaneously. When material A is trimmed for the second time, material B is trimmed for the first time simultaneously, and so on. Each forming process operates synchronously for its corresponding target forming material.

[0022] Furthermore, there can be one or more ejector mechanisms 5. An ejector mechanism 5 can be set every few upper mold processes 4, or an ejector mechanism 5 can be set between every two adjacent upper mold processes 4. Similarly, there can be one or more floating mechanisms 7. A floating mechanism 7 can be set every few lower mold processes, or a floating mechanism 7 can be set between every two adjacent lower mold processes. The specific number of floating mechanisms can be set based on the requirements, and there is no specific limitation here.

[0023] Understandably, this technical solution reduces changeover time and improves overall production efficiency by integrating multiple processes into the same mold. Furthermore, by setting up the guide frame 1, the material to be formed can be smoothly transferred to the conveyor belt, reducing material loss and waste during the conveying process.

[0024] In some embodiments, the upper mold mechanism 2 includes a mold closing pressure component 21 and a mold closing buffer component 22. The mold closing pressure component 21 is disposed above the mold closing buffer component 22, and a buffer gap exists between the mold closing pressure component 21 and the mold closing buffer component 22. The mold closing pressure component 21 and the mold closing buffer component 22 are connected by a guide component 8. When the upper mold mechanism 2 closes the mold to the lower mold mechanism 3, the mold closing pressure component 21 moves closer to the mold closing buffer component 22 along the guiding direction of the guide component 8, and the buffer gap between the mold closing pressure component 21 and the mold closing buffer component 22 decreases. It can be understood that the buffer design between the mold closing pressure component 21 and the mold closing buffer component 22 enables the mold to effectively absorb impact force during the mold closing process, thereby improving the stability and service life of the mold.

[0025] In some embodiments, the mold closing pressure assembly 21 includes an upper pad 211, an upper clamping plate 212, and an upper mold base 213 arranged sequentially from bottom to top in a direction away from the mold closing buffer assembly 22, and the upper pad 211, the upper clamping plate 212, and the upper mold base 213 are detachably connected by bolts 6; the mold closing buffer assembly 22 includes a stripper plate 221 and a stop plate 222 arranged sequentially from bottom to top in a direction away from the lower mold mechanism 3, and the stripper plate 221 and the stop plate 222 are detachably connected by bolts 6.

[0026] In some embodiments, the ejector mechanism 5 includes an ejector pin 51 and an ejector pin 52. One end of the ejector pin 51 is connected to the mold closing pressure assembly 21, and the other end of the ejector pin 51 is movably disposed in the ejector pin 52. The ejector pin 51 moves up and down with the mold closing or opening of the upper mold mechanism 2 and the lower mold mechanism 3. One end of the ejector pin 52 extends out of the bottom surface of the stripper plate 221. When the upper mold mechanism 2 closes the mold, the ejector pin head 53 of the ejector pin 51 extends out of the end of the ejector pin 52 and contacts the conveyor belt. When the upper mold mechanism 2 opens the mold, the ejector pin head 53 of the ejector pin 51 retracts into the ejector pin 52. Understandably, the design of the top material mechanism 5 stabilizes the conveyor belt in this position, thereby reducing shaking during the current forming process, improving forming stability, and thus improving forming quality. After the current forming process is completed, the top material mechanism 5 separates the conveyor belt from the ejector pin, facilitating further transport of the conveyor belt. Furthermore, the design of the top material mechanism 5 enables automated top material feeding, reducing manual intervention and improving the automation level and safety of production.

[0027] In some embodiments, the lower mold mechanism 3 includes a lower template 31, a lower pad 32, and a lower mold base 33 arranged sequentially from top to bottom away from the upper mold mechanism 2. The lower template 31 and the lower pad 32 are connected by bolts 6, and the lower pad 32 and the lower mold base 33 are also connected by bolts 6.

[0028] In some embodiments, the floating mechanism 7 includes a floating rod 71, a floating cylinder 72, and a floating pin 73. One end of the floating rod 71 is provided with a floating head 74, and the other end of the floating rod 71 can move up and down within the floating cylinder 72. When the floating rod 71 moves up and down within the floating cylinder 72, it causes the conveyor belt to be pushed out or dropped. The floating cylinder 72 and the floating pin 73 are threaded together to connect the lower template 31 and the lower pad 32. It is understood that the design of the floating mechanism 7 can float the conveyor belt after molding, improving the smoothness of the conveyor belt's transport. Furthermore, the floating cylinder 72 and the floating pin 73 are bolted together, allowing the floating mechanism 7 to both float the conveyor belt and connect the lower template 31 and the lower pad 32. In one example, the floating head 74 can be circular, rectangular, or other shapes, and can also be integrally formed with the top rod.

[0029] In some embodiments, the guide assembly 8 includes a guide post 81, a first guide sleeve 82, and a second guide sleeve 83. The first guide sleeve is formed on the stripper plate 221, and the second guide sleeve is formed on the lower mold plate 31. One end of the guide post 81 is connected to the mold closing pressure assembly 21, and the other end of the guide post 81 can slide within the first guide sleeve 82 and the second guide sleeve 83. It is understood that the arrangement of the guide assembly 8 (including the guide post 81, the first guide sleeve 82, and the second guide sleeve 83) enables smooth movement of the mold closing pressure assembly 21 during the mold closing process, reduces friction and wear, and extends the service life of the mold.

[0030] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
