Abstract
Description
Technical Field
[0001] This application belongs to the technical field of die-casting machines. More specifically, it relates to a die-closing mechanism with a double-link structure and a parting surface injection hot-chamber die-casting machine. Background Art
[0002] As a type of die-casting machine, the injection chamber and injection plunger of a hot-chamber die-casting machine are immersed in molten metal. Its working principle is that the injection chamber is connected to the gate of the die-casting mold through a gooseneck, and then the production of products made of alloy materials such as aluminum, magnesium, and zinc is realized through such a structure. With the increasing market demand for more complex die-cast products, it is necessary to develop larger hot-chamber die-casting machines to increase the size of the die-closing unit, especially the mold in the die-closing unit. However, with the increase in size, the machine's requirement for die-closing force is also getting higher and higher. In the currently common die-closing unit structure design, the driving member usually drives the moving template through a single link to move the moving template towards the fixed template, and then the die-closing of the moving die and the fixed die is realized to form a mold. However, in the case of a relatively high die-closing force, the existing single-link design is prone to the risk of poor machine durability. In addition, when the size increases, the existing design will have the problem that the injection nozzle must be lengthened, but the lengthened injection nozzle is prone to problems such as blockage of the molten metal in the nozzle and an increase in the use cost of auxiliary heating parts. Therefore, how to effectively avoid the risk of poor durability in a die-closing unit with a larger size and a relatively high die-closing force, and at the same time reduce the length of the injection nozzle has become an urgent problem in the industry.

[0036] An embodiment of the present application provides a mold clamping mechanism with a double-link structure.
[0037] Please refer to Figures 1 to 4 , in one embodiment, the mold clamping mechanism with the double-link structure 520 is used for a parting surface injection hot chamber die casting machine, which includes a main body substrate 100, a gooseneck 210 installed on the rear side of the main body substrate 100, and a nozzle 220 provided at the front end of the gooseneck 210 and passing through the main body substrate 100. Specifically, the mold clamping mechanism with the double-link structure 520 includes a moving mold 410 assembly, a fixed mold 310 assembly, a mold clamping assembly, a mold substrate 600, and a guide rod assembly. Among them, the moving mold 410 assembly includes a moving mold 410 and a moving template 420 for installing the moving mold 410; the fixed mold 310 assembly includes a fixed mold 310 and a fixed template 320 for installing the fixed mold 310. The mold clamping assembly includes a link outer shell plate 510, a double-link structure 520, and a first driving member 530; the link outer shell plate 510 is connected to the moving template 420 through the double-link structure 520, and the first driving member 530 is provided on the side of the link outer shell plate 510 facing away from the moving template 420. The lower ends of the fixed template 320, the moving template 420, and the link outer shell plate 510 are all connected to the mold substrate 600. The guide rod assembly includes an upper guide rod 710, and the upper guide rod 710 passes through the upper region of the link outer shell plate 510 and the moving template 420 in sequence and then is connected to the fixed template 320. During the mold clamping process, the link outer shell plate 510 is driven by the first driving member 530, and drives the moving template 420 and the moving mold 410 to move towards the fixed template 320 through the double-link structure 520, so that the moving mold 410 and the fixed mold 310 are clamped to form a mold; the mold substrate 600 is driven to drive the mold 410 towards the main body substrate 100, so that the injection port of the mold abuts against and communicates with the nozzle 220. At this time, the upper guide rod 710 is located above the top of the main body substrate 100.
[0038] Based on this design, in this embodiment, on the one hand, since the double-link structure 520 is used to connect the moving template 420 and the connecting rod outer shell plate 510, when the first driving member 530 drives the connecting rod outer shell plate 510 to move, especially when the clamping force is large, the double-link structure 520 can drive the moving template 420 to move better than the single-link design, effectively avoiding the risk of poor durability of the single-link connection, thereby ensuring the durability of the machine. Moreover, since the ejection mechanism is usually built into the movable template 420, using the double-link structure 520 can also avoid the occurrence of situations such as the ejection mechanism shifting. On the other hand, in the final clamping state, that is, when the nozzle 220 abuts and communicates with the injection port of the mold, since the upper convex portion 422 and the upper guide rod 710 are both located above the upper end of the main body substrate 100, the moving template 420 and the fixed template 320 can effectively avoid position conflicts with the main body substrate 100 after clamping, so that the nozzle 220 can be closer to the mold and effectively reduce its length. In this way, advantages such as facilitating the temperature control of the nozzle 220, reducing the risks of nozzle 220 blockage and molten metal splashing, reducing the cost of related heating accessories, and improving the die-casting performance can be obtained. In summary, the technical solution of this application can achieve the effect of effectively avoiding the risk of poor durability in a large-size clamping mechanism with a high clamping force and at the same time reducing the length of the nozzle 220.
[0039] Please refer to Figures 1 to 3 , in this embodiment, the double-link structure 520 is specifically a double toggle link, including a first toggle link 521 and a second toggle link 522 arranged side by side at intervals. Of course, in other embodiments, it can also be other types of link designs. However, in this embodiment, the toggle link design can better stably transmit the clamping force of the first driving member 530 to the moving die 410 assembly, and can reduce and relieve the impact force accidentally generated by the first driving member 530, improve the force stability of the moving die 410 assembly, and thus is beneficial to improving the die-casting quality.
[0040] Furthermore, as Figures 1 to 4As shown, in this embodiment, the fixed template 320, the movable template 420, and the connecting rod outer shell plate 510 are arranged in parallel at intervals; the fixed template 320 and the movable template 420 each include a middle part, an upper convex part 422, and a lower convex part 423; the upper convex part 422 protrudes backward from the upper region of the rear side of the middle part; the lower convex part 423 protrudes forward from the lower region of the front side of the middle part; the mold is installed in the middle part. Accordingly, both ends of the first toggle link 521 and the second toggle link 522 are respectively connected to the middle part of the movable template 420 and the middle part of the connecting rod outer shell plate 510; the first toggle link 521 and the second toggle link 522 are located between the upper convex part 422 and the lower convex part 423, and are arranged at intervals up and down. It can be understood that this special compact structure design of the fixed template 320, the movable template 420, and the connecting rod outer shell plate 510 can make the widths of the respective plate members narrower, thereby facilitating material saving, weight reduction, widening the space around the mold for easy installation and disassembly of the mold, and improving the interference around the nozzle 220 to facilitate the nozzle 220 to become shorter. In addition, the guide rod assembly further includes a lower guide rod 720, and the lower guide rod 720 sequentially passes through the lower region of the front side of the connecting rod outer shell plate 510, the lower convex part 423 of the movable template 420, and the lower convex part 423 of the fixed template 320, and is connected to the fixed template 320. In fact, the first toggle link 521 and the second toggle link 522 are also located between the upper guide rod 710 and the lower guide rod 720. Here, compared with the common four-guide rod design in the prior art, the double-guide rod design of the upper guide rod 710 and the lower guide rod 720 in this embodiment occupies less space, which is conducive to the convenient disassembly and assembly of the fixed mold 310 assembly and the movable mold 410 assembly.
[0041] Please refer to Figures 1 to 3 , further, in this embodiment, the rotation connection point of the double-link structure 520 and the movable mold 410 assembly is located at the geometric center of the movable mold 410 assembly. In this way, the clamping force can be directly transmitted to the center of the mold, and the clamping force is evenly and balancedly distributed, which is conducive to improving the movement stability of the movable mold 410 assembly.
[0042] Please refer to Figure 1 and Figure 2, in this embodiment, the mold clamping mechanism with the double-link structure 520 further includes a moving mold sliding guide rail 610. The moving mold sliding guide rail 610 is installed on the mold substrate 600 and is located below the moving template 420. The moving template 420 moves towards the fixed template 320 on the moving mold sliding guide rail 610. During the actual operation process, the mold clamping process of the present application includes the process of the moving mold 410 and the fixed mold 310 being clamped to form a mold and the process of the mold being driven by the mold substrate 600 to contact and communicate with the nozzle 220. During the mold clamping process, after being driven, the moving template 420 will move towards the fixed template 320 along the moving mold sliding guide rail 610 until the moving mold 410 and the fixed mold 310 are clamped; during the mold clamping process of the mold and the nozzle 220, it is realized by the mold substrate 600 being driven to drive the mold 410 towards the main body substrate 100. In addition, as Figure 2 shown, to further reduce the movement resistance of the moving template 420, there is a gap between the lower end of the lower convex portion 423 of the moving template 420 and the mold substrate 600.
[0043] Please refer to Figures 1 to 3 , in this embodiment, the first driving member 530 is a mold clamping oil cylinder, and the mold clamping oil cylinder is installed in the middle area of the middle part of the link housing plate 510. Specifically, during the mold clamping process of the moving mold 410 and the fixed mold 310, the mold clamping oil cylinder drives the link housing plate 510, and then drives the movable template 420 through the first toggle link 521 and the second toggle link 522 to generate a clamping force. Installing the mold clamping oil cylinder in the middle area of the middle part of the link housing plate 510 is beneficial to directly transmit the driving force, so that the movement of the moving template 420 is more stable and the force is more uniform.
[0044] Furthermore, please refer to Figure 1 and Figure 3 , in this embodiment, taking the axial direction of the upper guide rod 710 as the left-right direction, the link housing plate 510 is arranged to cover the moving template 420 in the direction from right to left. In other words, the size of the link housing plate 510 should be larger than that of the moving template 420 and the fixed template 320, that is, when looking from right to left, the link housing plate 510 is arranged to cover the moving template 420. In this way, the movement stability of the link housing plate 510 can be improved. Of course, in this embodiment, the link housing plate 510 is also provided with an upper convex portion 422, and the upper guide rod 710 passing through the upper convex portion 422 is also located above the top end of the main body substrate 100 after the nozzle 220 is clamped in place. In this way, the link housing plate 510 will not interfere with the main body substrate 100, which is beneficial to shortening the length of the nozzle 220.
[0045] The present application also provides a die-casting machine with a parting surface injection hot chamber. The die-casting machine with a parting surface injection hot chamber includes a main body substrate 100, a gooseneck 210, a nozzle 220, and a die-closing mechanism having a double-link structure 520 as described above. The gooseneck 210 is installed in the upper region of the rear side surface of the main body substrate 100 facing away from the mold, and the nozzle 220 is provided at the front end of the gooseneck 210 and passes through the main body substrate 100. For the specific structure of the die-closing mechanism having the double-link structure 520, reference may be made to the above embodiments. Since the die-casting machine with a parting surface injection hot chamber adopts all the technical solutions of the above embodiments, it also has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated herein one by one.
[0046] In addition, please refer to Figure 4 , in this embodiment, both the die-closing mechanism having the double-link structure 520 and the main body substrate 100 are inclined backward, and the mold substrate 600 is perpendicular to the main body substrate 100. The axial direction of the nozzle 220 is perpendicular to the mating surface of the moving mold 410 and the stationary mold 310 facing the gooseneck 210. This design can raise the front end of the nozzle 220 to prevent molten metal from overflowing from the front end of the nozzle 220; and the design that the mold substrate 600 is perpendicular to the main body substrate 100 is beneficial to ensuring that the mold and the nozzle 220 are perpendicular to each other, thereby better preventing molten metal from overflowing.
[0047] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
