Description

Technical Field

[0001] This application relates to the field of die casting molding technology for die casting machines, and in particular to a molding device for a die casting machine. Background Technology

[0002] Die casting machines, as important industrial production equipment, are widely used in the automotive, electronics, and aerospace industries. Their core function is to inject molten metal into a precision mold under high pressure, which then rapidly cools and solidifies to form metal parts. This process mainly includes injection, mold closing and molding, pressure holding, cooling, mold opening, and part removal. With the continuous development of the manufacturing industry, the market demands higher performance from die casting machines, especially for miniaturization, efficiency, and operational safety. While traditional die casting machine designs meet basic production needs to a certain extent, they still have many limitations in practical applications and urgently require further optimization to enhance overall competitiveness. Currently, die-casting machines include a material extrusion mechanism, a mold-closing mechanism, and a drive mechanism that provides power to the die-casting machine. The material extrusion mechanism pushes the molten metal in the pressure chamber at a preset speed, providing sufficient energy to make it flow through the mold of the mold-closing mechanism and then to the mold gate to fill the mold forming cavity. In order to realize mold closing and opening, the mold-closing mechanism is equipped with a moving mold group, a stationary mold group, and guide members. The moving mold group can slide on the guide members. Driven by a cylinder, the moving mold group reciprocates between the moving mold group and the stationary mold group under the guidance of the guide members. The existing design usually arranges a large-size cylinder horizontally on one side of the moving mold group to drive the moving mold group to move, so as to realize the mold closing and opening between the moving mold group and the stationary mold group. It is widely used because of its simple structure and low cost.

[0003] However, the layout of the aforementioned die-casting machines has significant shortcomings, especially in applications involving large-size die-casting machines. Firstly, the horizontal placement of the cylinders occupies considerable lateral space, significantly increasing the overall machine footprint and limiting equipment density per unit area in the workshop, thus reducing overall factory production efficiency. Secondly, die-casting machines typically heat the material within the injection molding assembly to melt it and shape it for die-casting. However, cylinders located near high-temperature operating areas are usually connected to multiple air pipes or electrical wires. Under high-temperature conditions, plastic air pipes are prone to softening, deformation, or accelerated aging, affecting not only the stability of the air supply but also potentially posing safety hazards. Furthermore, the disorganized pipeline layout reduces the cleanliness of the equipment's appearance, failing to meet the aesthetic requirements of modern factories. These problems urgently require new design solutions. Utility Model Content

[0004] In order to reduce the footprint of the die-casting machine, increase the equipment layout density per unit area in the workshop, improve the overall production efficiency of the factory and the stability of the cylinder's normal air supply, and improve the equipment's aesthetics and safety performance, this application provides a molding device for a die-casting machine.

[0005] To achieve the above objectives, this application provides a forming apparatus for a die-casting machine, including a frame and an extrusion mechanism, a mold-closing mechanism, and a drive control mechanism for driving the extrusion mechanism and the mold-closing mechanism, all disposed on the frame. The discharge end of the extrusion mechanism is connected to the feed end of the mold-closing mechanism. The mold-closing mechanism includes a stationary mold assembly, a moving mold assembly, a first fixed seat, a balance plate, and guide members. The guide members are all located between the stationary mold assembly and the first fixed seat. The balance plate is horizontally disposed at one end of the frame near the discharge end of the extrusion mechanism. The stationary mold assembly, the moving mold assembly, and the first fixed seat are sequentially spaced on the upper surface of the balance plate. The drive control mechanism includes a toggle assembly and a cylinder for driving the toggle assembly. The cylinder is disposed on the balance plate away from the guide members. On one side of the component, the toggle assembly includes a first connecting rod and a second connecting rod. One end of the first connecting rod is hinged to the side of the moving module near the first fixed seat, and the other end of the first connecting rod is hinged to one end of the second connecting rod. The other end of the second connecting rod is hinged to the side of the first fixed seat near the moving module. A connecting rod neck is provided at the end of the second connecting rod near the cylinder where it connects to the first connecting rod. The connecting rod neck is hinged to the end of the telescopic rod of the cylinder. The balance plate is provided with a first through cavity. The first through cavity is located between the moving module and the first fixed seat. Both the first connecting rod and the second connecting rod pass through the first through cavity. When the cylinder drives the toggle assembly, the toggle assembly pushes the moving module to reciprocate along the guide member.

[0006] By adopting the above technical solution, the cylinder is positioned on the side of the balance plate away from the guide member, and the first and second connecting rods in the toggle assembly are used to drive the moving module. This design effectively reduces the lateral space occupation problem caused by traditional horizontally arranged large-size cylinders. At the same time, since the cylinder is located away from the high-temperature operating area, the risk of softening, deformation, or aging of the air guide tube due to the high-temperature environment is avoided. When the cylinder extends or retracts, it pushes the connecting rod neck upward, which in turn drives the connection between the first and second connecting rods upward. This causes the first and second connecting rods to push the moving module horizontally under the constraint of the guide member, thus transforming the vertical pushing of the cylinder into the horizontal pushing of the connecting rod. This design significantly reduces the overall footprint of the equipment, improves the stability and safety of the system, and ensures the smoothness and accuracy of the moving module during reciprocating movement, further improving the quality and consistency of die-cast products.

[0007] Preferably, the stationary mold assembly includes a stationary mold base and a stationary mold, the stationary mold base is fixed to the balance plate, the stationary mold is disposed on the side of the stationary mold base near the moving mold assembly, and the side of the stationary mold base near the stationary mold is connected to the guide member.

[0008] By adopting the above technical solution, the static mold assembly consists of a static mold base and a static mold. The static mold base is fixed to the balance plate, providing a stable support foundation for the entire static mold assembly. Because the static mold base is connected to the guide component, this design makes the position of the static mold assembly more stable, avoiding positional shifts or wobbling caused by external forces during die casting. Simultaneously, the static mold is installed on the side of the static mold base closest to the moving mold assembly. This layout facilitates precise alignment with the moving mold in the moving mold assembly, ensuring high precision when the two close to form a complete mold cavity. This improvement effectively enhances the dimensional accuracy and surface quality of the final die-cast product, while also improving the reliability and consistency of the die-casting process.

[0009] Preferably, the moving module includes: a moving mold base and a moving mold, the moving mold base is suspended above the balance plate, the moving mold is disposed on the side of the moving mold base close to the stationary mold, the moving mold base is provided with a through hole, and the guide member passes through the through hole so that the moving mold base drives the moving mold to reciprocate along the guide member.

[0010] By adopting the above technical solution, the moving mold assembly consists of a moving mold base and a moving mold. The moving mold base is suspended above the balance plate, avoiding the interference problem caused by the moving mold directly contacting the bottom support structure in traditional layouts. The moving mold base has through holes for guide members to pass through, allowing the moving mold base to achieve stable and reliable reciprocating movement with the precise guidance of the guide members. Specifically, when the drive control mechanism operates, the generated driving force is transmitted to the moving mold base via the transmission system, thereby driving the connected moving mold to slide precisely along the guide members. This structural arrangement not only effectively improves the linearity and accuracy of the moving mold assembly's movement trajectory but also significantly enhances the stability of the entire mold closing process, thereby reducing molding defects caused by vibration or misalignment. Furthermore, since the guide members penetrate the moving mold base and act as a constraint, this design can also effectively disperse the inertial force generated by the moving mold assembly during high-speed movement, further improving the safety and reliability of equipment operation. In summary, this technical solution, through the optimization and improvement of the moving mold assembly structure and its mating relationships, ensures efficient production while also providing strong guarantees for the quality of die-cast products.

[0011] Preferably, the static mold has a first injection groove on the side close to the moving mold, and the moving mold has a second injection groove corresponding to the first injection groove. The first injection groove and the second injection groove surround to form a mold forming cavity, which is located in the cuboid cavity surrounded by the guide member.

[0012] By adopting the above technical solution, the static mold and the moving mold are arranged opposite each other, and a first injection groove and a second injection groove are respectively opened. When the corresponding surfaces of the two are in contact, the first injection groove and the second injection groove cooperate with each other to form a mold forming cavity for molding the target product. Since the mold forming cavity is located inside the cuboid cavity surrounded by four guide members, it can play a certain protective role, preventing external factors from interfering with the molding process, thereby improving the overall structural compactness and operational reliability of the die-casting machine.

[0013] Preferably, the balance plate is provided with a second through cavity, which is located between the static mold and the moving mold, and the material after being formed by the mold forming cavity passes through the second through cavity.

[0014] By adopting the above technical solution, a second passage cavity is set on the balance plate, and this second passage cavity is located between the stationary mold and the moving mold. This design makes full use of the spatial layout characteristics of the molding device, opening a channel in the area between the stationary mold and the moving mold, so that the material after molding in the mold forming cavity can be directly discharged through the second passage cavity. Since the second passage cavity is located in the middle area between the moving mold group and the stationary mold group, the need for an additional independent material discharge mechanism is avoided, simplifying the overall structure. At the same time, this design can also effectively reduce the jamming phenomenon caused by the complex path of material during discharge, improving the working efficiency and reliability of the die-casting machine. In addition, by rationally planning the material discharge path, it also helps to keep the surrounding environment of the equipment clean and orderly, facilitating the smooth progress of subsequent processing or collection processes.

[0015] Preferably, the extrusion mechanism includes a feeding component and an extrusion component. The discharge end of the feeding component is connected to the feed end of the extrusion component. The discharge end of the extrusion component is provided with an extrusion die, and the discharge end of the extrusion die is connected to the feed end of the mold forming cavity.

[0016] By adopting the above technical solution, the extrusion mechanism consists of a feeding component and an extrusion component. The two components are connected at the discharge end and the feed end, enabling continuous material transfer from its initial state to a die-castable state. Specifically, the feeding component is responsible for feeding solid raw materials into the system, where they are internally heated or otherwise processed to transform them into molten metal suitable for the die-casting process. Subsequently, this molten metal flows into the extrusion component, where it gains sufficient pressure and fluidity. Finally, the extrusion die head, located at the discharge end of the extrusion component, precisely injects the controlled flow and pressure of the metal into the mold cavity to complete the filling action. This design not only ensures a high degree of automation and stability throughout the process but also effectively improves injection molding accuracy and production efficiency, laying the foundation for the stable production of high-quality products.

[0017] Preferably, the balance plate is provided with a first limiting block, which is located between the moving mold base and the first fixed seat. The first limiting block is provided with a first limiting through hole, and the guide member passes through the first limiting through hole. When the moving mold base moves toward the first fixed seat, the moving mold base abuts against the first limiting block.

[0018] By adopting the above technical solution, the first limiting block set on the balance plate plays a crucial role in the process of the moving mold base moving towards the first fixed seat. Specifically, the first limiting block is located between the moving mold base and the first fixed seat, and has a first limiting through hole for the guide component to pass through. This design allows the first limiting block to be accurately positioned when the moving mold base slides along the guide component, effectively preventing the moving mold base from getting too close to the first fixed seat due to inertia or other external forces, thus preventing damage. When the moving mold base reaches the predetermined position, it will contact the first limiting block and stop moving, thereby ensuring the safety and stability of the entire mold closing process. At the same time, this structure can also ensure the fitting accuracy between molds and avoid affecting the quality of the final product due to stroke errors.

[0019] Preferably, the balance plate is provided with a second limiting block, which is located between the moving mold base and the first fixed seat. The second limiting block and the first limiting block are correspondingly arranged on both sides of the balance plate. The second limiting block is provided with a second limiting through hole, and the guide member passes through the second limiting through hole. When the moving mold base moves toward the first fixed seat, the moving mold base abuts against the second limiting block and the first limiting block at the same time.

[0020] By adopting the above technical solution, a second limiting block is added and positioned on both sides of the balance plate along with the first limiting block, thus providing limiting and balancing protection as the moving mold base moves toward the first fixed seat. Specifically, when the moving mold base moves along the guide and gradually approaches the first fixed seat, the moving mold base contacts the first and second limiting blocks simultaneously. This effectively prevents structural damage or positional deviation caused by excessive movement of the moving mold base. Furthermore, since the moving mold base is pierced by four guides, the limiting blocks on both sides of the balance plate allow the moving mold base to be abutted at multiple points, resulting in a more balanced force on the balance plate along the guides. This design not only improves the stability and reliability of the device operation but also avoids localized wear caused by single-point force, thereby extending the equipment's service life.

[0021] Preferably, the second limiting block is disposed on the side of the balance plate near the feeding component, and the second limiting block is also provided with a limiting groove. The feeding component is provided with a limiting rod. During die casting, the end of the limiting rod falls into the limiting groove and abuts against the bottom of the limiting groove.

[0022] By adopting the above technical solution, before the feeding assembly conveys the material to the extrusion assembly for processing, the equipment needs to be debugged to achieve precise connection between the extrusion die and the forming cavity. The alignment of the extrusion die and the forming cavity is determined by whether the end of the limiting rod can fall into the limiting groove of the second limiting block and abut against the bottom of the groove. This design ensures precise docking between the dies and enhances the stability of the entire forming device during operation, thereby improving the consistency of the final product quality.

[0023] Preferably, the drive control mechanism further includes a control system, which is disposed on one side of the frame, electrically connected to the extrusion assembly, and connected to the input air path of the cylinder.

[0024] By adopting the above technical solution, and adding a control system that is electrically connected to the extrusion assembly and to the pneumatic input of the cylinder, a high degree of integrated control of the entire die-casting machine's forming device is achieved. Specifically, the control system is located on one side of the frame. This design not only saves space but also facilitates centralized management of various parameters by operators. Electrical connection to the extrusion assembly allows for precise control of the pressure and speed of the extrusion mechanism, ensuring that molten metal flows into the mold forming cavity in optimal condition, thereby improving product yield. Simultaneously, precise control of the cylinder's movement through the pneumatic connection ensures smooth movement of the moving die while effectively avoiding adverse effects caused by excessive extrusion or sluggish movement. This electrical integration significantly enhances the overall stability and reliability of the equipment, laying a solid foundation for automated production.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting the cylinder on the side of the balance plate away from the guide, and using a toggle assembly to realize the relative movement between the moving and stationary modules, the problem of lateral space occupation caused by the layout design of the existing die-casting machine is effectively reduced, thereby reducing the overall size of the equipment and improving the space utilization and production efficiency of the workshop; at the same time, it significantly reduces the risk of softening, deformation or aging of the air pipe caused by heat radiation, and improves the reliability and safety of the system operation.

[0027] 2. The rectangular cavity formed by the four guide members and the precise guiding structure ensure the stability and accuracy of the moving module during reciprocating movement, which helps to improve the mold closing accuracy and the quality of the final product.

[0033] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0034] This application discloses a forming apparatus for a die-casting machine, referring to... Figure 1It includes a frame 1 and an extrusion mechanism 2, a mold closing mechanism 3 and a drive control mechanism 4 mounted on the frame 1. The extrusion mechanism 2 is used to inject molten metal into the mold closing mechanism 3, and the drive control mechanism 4 is responsible for controlling the cooperative operation of the extrusion mechanism 2 and the mold closing mechanism 3 to achieve die casting.

[0035] Specifically, the mold closing mechanism 3 includes a balance plate 31 horizontally installed on the frame 1, a stationary mold assembly 32 and a first fixed seat 34 spaced apart on the upper surface of the balance plate 31, a moving mold assembly 33 disposed between the stationary mold assembly 32 and the first fixed seat 34, and a guide member 35. In this embodiment, the guide member 35 consists of four guide rods, which are arranged parallel to each other and form a rectangular cavity. Specifically, all four guide rods are located directly above the balance plate 31. The stationary mold assembly 32, the moving mold assembly 33, and the first fixed seat 34 are all located within the cavity of the four guide rods. One end of each of the four guide rods is fixedly connected to the stationary mold assembly 32, and the other end of each of the four guide members 35 is fixedly connected to the first fixed seat 34. The moving mold assembly 33 is provided with four guide holes through which the four guide rods can pass. The four guide rods pass through the four guide holes, allowing the moving mold assembly 33 to move horizontally back and forth between the stationary mold assembly 32 and the first fixed seat 34 along the guide member 35. The guide component 35 can be made of high-strength alloy steel, because this type of material is not only hard and not easy to wear, but can also resist temperature fluctuations within a certain range.

[0036] Among them, such as Figure 2 As shown, the stationary mold assembly 32 includes a stationary mold base 321 and a stationary mold 322. The stationary mold base 321 is fixed to the upper surface of the balance plate 31. The stationary mold 322 is disposed on the side of the stationary mold base 321 near the moving mold assembly 33. The side of the stationary mold base 321 near the stationary mold 322 is connected to the guide member 35. The side of the stationary mold 322 near the moving mold assembly 33 is provided with a first injection groove 3221. In this embodiment, both the stationary mold base 321 and the stationary mold 322 are cuboids, and four guide members 35 are respectively fixed at the four corners of the stationary mold base 321.

[0037] The moving module 33 includes a moving mold base 331 and a moving mold 332. The moving mold base 331 is suspended above the balance plate 31. The moving mold 332 is disposed on the side of the moving mold base 331 near the stationary mold 322. The moving mold base 331 is provided with a through hole. The guide member 35 passes through the through hole so that the moving mold base 331 drives the moving mold 332 to move back and forth along the guide member 35. The moving mold 332 is provided with a second injection groove 3321 corresponding to the first injection groove 3221. The first injection groove 3221 and the second injection groove 3321 surround to form a mold forming cavity for containing liquid materials. In this embodiment, the first fixed base 34 is designed as a cuboid, and four guide members 35 are respectively fixed at the four corners of the first fixed base 34. The moving mold base 331 and the moving mold 332 are also designed as cuboids, corresponding to the stationary mold base 321 and the stationary mold 322. The four corners of the moving mold base 331 are provided with through holes, and the four guide members 35 are respectively set through the four through holes, thereby forming a stable mold opening and closing structure between the stationary mold group 32, the moving mold group 33, the first fixed base 34, and the guide members 35.

[0038] Specifically, the balance plate 31 also has a first through cavity 311 and a second through cavity 312. The first through cavity 311 is located between the moving mold base 331 and the first fixed base 34, and the second through cavity 312 is located between the stationary mold 322 and the moving mold 332, and is located directly below the mold forming cavity. The material after being formed by the mold forming cavity falls from the second through cavity 312 and is collected. Specifically, a material collection box can be placed directly below the second through cavity 312 to collect the material.

[0039] Specifically, the extrusion mechanism 2 includes a feeding assembly 21 responsible for material conveying and an extrusion assembly 22 that extrudes the material after high-temperature treatment into the mold forming cavity. The discharge end of the feeding assembly 21 is connected to the feed end of the extrusion assembly 22 to ensure smooth material conveying. The discharge end of the extrusion assembly 22 is equipped with an extrusion die 221, which is connected to the feed end of the mold forming cavity to achieve precise injection molding. Specifically, such as... Figure 3 As shown, the balance plate 31 is equipped with a first limiting block 5, which is located between the moving mold base 331 and the first fixed seat 34. The first limiting block 5 has a first limiting through hole 51, and at least one guide member 35 passes through the first limiting through hole 51. When the moving mold base 331 moves toward the first fixed seat 34, the moving mold base 331 abuts against the first limiting block 5. Alternatively, the first limiting block 5 may have two first limiting through holes 51, with two guide members 35 on the side away from the extrusion mechanism passing through the corresponding first limiting through holes 51, which can further enhance the operational stability of the mold closing mechanism 3 and improve the balance of the moving mold assembly 33 during movement.

[0040] Furthermore, the balance plate 31 is also provided with a second limiting block 6. The second limiting block 6 is located between the moving mold base 331 and the first fixed seat 34 and is correspondingly set on both sides of the balance plate 31 with the first limiting block 5. The second limiting block 6 is provided with a second limiting through hole 61, and at least one guide member 35 passes through the second limiting through hole 61. When the moving mold base 331 moves toward the first fixed seat 34, the moving mold base 331 abuts against the second limiting block 6 and the first limiting block 5 at the same time. The second limiting block 6 can also be provided with two second limiting through holes 61. The two guide members 35 near the extrusion mechanism 2 pass through the corresponding second limiting through holes 61, which can further enhance the operational stability of the mold closing mechanism 3 and improve the balance when the moving mold assembly 33 moves. It is worth mentioning that the second limiting block 6 is also provided with a limiting groove 62. The feeding assembly 21 is provided with a limiting rod 211. Before die casting, the end of the limiting rod 211 needs to be adjusted so that it falls into the limiting groove 62 and abuts against the bottom of the limiting groove 62.

[0041] Specifically, the drive control mechanism 4 includes a cylinder 41, an elbow assembly 42 connected to the end of the telescopic rod of the cylinder 41, and a control system 43 disposed on one side of the frame 1. The control system 43 is electrically connected to the extrusion assembly 22 and is connected to the input air path of the cylinder 41. Wherein, as Figure 4 As shown, the toggle assembly 42 includes a first connecting rod 421 and a second connecting rod 422. Hinges are provided on both the side of the moving mold base 331 near the first fixed seat 34 and the side of the first fixed seat 34 near the moving mold base 331. One end of the first connecting rod 421 is hinged to the hinge of the moving mold base 331, and the other end of the first connecting rod 421 is hinged to one end of the second connecting rod 422. The other end of the second connecting rod 422 is hinged to the hinge of the first fixed seat 34 near the moving mold 33. Specifically, a connecting rod neck 4221 extends downwards from the connection point of the first connecting rod 421 and the second connecting rod 422. The connecting rod neck 4221 passes through the first through cavity 311 and connects to the end of the telescopic rod of the cylinder 41, forming a complete force transmission chain. This design avoids the space waste problem caused by traditional single-plane expansion, instead utilizing the potential for vertical development to maximize the saving of ground space. The cylinder 41 is vertically mounted on the lower end face of the balance plate 31. Only a small space is needed for the first through cavity 311 to accommodate the linkage of the first connecting rod 421 and the second connecting rod 422. This avoids the extrusion component 22 heating up and affecting the stability of the cylinder 41, which is both aesthetically pleasing and improves the safety of equipment operation.

[0042] The implementation principle of this embodiment is as follows: The device mainly consists of a frame 1, an extrusion mechanism 2, a mold clamping mechanism 3, and a drive control mechanism 4. In the process flow, molten metal is first transported by the feeding component 21 of the extrusion mechanism 2 to the extrusion component 22 for high-temperature treatment, and then precisely injected into the mold forming cavity of the mold clamping mechanism 3 through the extrusion die head 221. The mold clamping mechanism 3 is composed of a balance plate 31, a stationary mold assembly 32, a moving mold assembly 33, a first fixed seat 34, and four guide members 35 made of high-strength alloy steel. The stationary mold assembly 32 and the first fixed seat 34 are respectively installed at both ends of the guide members 35. The moving mold assembly 33 is located between the stationary mold assembly 32 and the first fixed seat 34 and moves horizontally back and forth along the guide members 35. The moving mold assembly 33 and the stationary mold assembly 32 cooperate to form the mold forming cavity. The balance plate 31 below the mold forming cavity is provided with a second through cavity 312 to facilitate the collection of the material after molding. The drive control mechanism 4 drives the moving module 33 to move via cylinder 41 and toggle assembly 42, realizing the opening and closing of the mold. Cylinder 41 is vertically mounted at the lower end of the balance plate 31, saving space and avoiding thermal interference. The toggle assembly 42 utilizes a vertical connecting rod design to optimize force transmission. Furthermore, the balance plate 31 is equipped with a first limit block 5 and a second limit block 6. A guide member 35 with a limit through-hole enhances the stability of the mold closing mechanism 3 and the balance of the moving module 33 during movement. Before die casting, the limit rod 211 of the feeding assembly 21 needs to be adjusted to abut against the limit groove 62 of the second limit block 6 to ensure proper preparation. The entire device design reduces the footprint of the die casting machine, increases the equipment density per unit area in the workshop, improves the overall production efficiency of the factory and the stability of the cylinder's normal air supply, and enhances both the aesthetics and safety performance of the equipment.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
