Description

Technical Field

[0001] This utility model relates to the field of die casting machine technology, specifically to a die casting machine mold bridge frame structure with a split support structure. Background Technology

[0002] Currently, die-casting machines use a frame slide rail mold bridge with a single-support structure. For example, Chinese patent document CN212371141U describes a sliding device and a die-casting machine. It includes: a frame; a linear guide rail, which includes a slide rail and a first slider, the slide rail being mounted on the frame, the first slider being slidably connected to the slide rail, and a rolling element being disposed between the first slider and the slide rail; a first slide block, mounted on the first slider; and a mold bridge for supporting the mold, the mold bridge being mounted on the first slide block and not in direct contact with the frame, and the mold bridge being able to slide along the slide rail with the first slide block.

[0003] The single-support structure has the following problems during use: First, the structural rigidity is insufficient. The mold bridge and the sliding foot of the moving template share the frame support rail, resulting in an excessively large support span. Under the action of large machines and oversized molds, the deflection in the middle of the mold bridge can reach more than 0.3 mm / m. Second, the space utilization rate is low. The shared support structure requires reserved space for the sliding foot movement and the thickness of the mold bridge itself, which limits the minimum mold thickness. Third, the stress is concentrated. The weight borne by the frame is concentrated on the single support rail, which can easily cause excessive local deformation of the guide rail. Fourth, thermal deformation interference. The heat (up to 80℃) generated by the sliding friction of the template is directly conducted to the mold bridge support surface and the frame surface.

[0004] To address the aforementioned problems in existing technologies, it is necessary to design a die-casting machine mold bridge that can achieve high structural rigidity, high space utilization, uniform stress distribution, no deformation of the guide rail, and minimal thermal deformation interference. Utility Model Content

[0005] The purpose of this invention is to solve the problems of existing die-casting machine single-support structures, such as large support span, insufficient structural rigidity, low space utilization, limited minimum mold thickness, concentrated stress, and easy excessive local deformation of the guide rail, as well as interference from thermal deformation. The invention provides a die-casting machine mold bridge frame structure with a split double-support structure, small span, reasonable force transmission path, independent inward mold bridge support mechanism, reasonable space layout, which can significantly shorten the minimum mold thickness and meet the needs of more mold thicknesses.

[0006] The technical solution adopted by this utility model to achieve its invention objective is: a die-casting machine mold bridge frame structure, including a mold bridge frame body, on which a separate double-support sliding mechanism is provided, the separate double-support sliding mechanism including an inward mold bridge support sliding mechanism and an independent moving template sliding support mechanism; the inward mold bridge support sliding mechanism is separately arranged inside the independent moving template sliding support mechanism. This die-casting machine's mold bridge frame structure features a redesigned, dual-support sliding mechanism. Specifically, this mechanism includes a mold bridge support sliding mechanism and an independent moving template sliding support mechanism. The mold bridge support sliding mechanism is recessed and positioned inside the independent moving template sliding support mechanism. During operation, the fixed mold bridge and moving mold bridge are directly mounted on the mold bridge support sliding mechanism, while the moving template is independently mounted on its own mechanism. The mold bridge and moving template no longer share the same support mechanism; instead, they have separate support mechanisms. The recessed mold bridge support sliding mechanism and the independent moving template sliding support mechanism are separate and do not interfere with each other. This significantly shortens the mold bridge's support span, effectively solving the problem of insufficient structural rigidity. The separation of the recessed mold bridge support sliding mechanism and the independent moving template sliding support mechanism allows for full space utilization, eliminating space limitations on the minimum mold thickness and meeting the die-casting needs of molds with varying thicknesses. It also solves the problem of concentrated stress. Furthermore, the heat generated by friction during the moving template movement is not directly conducted to the mold bridge support surface and the frame surface, effectively preventing thermal deformation interference. The die-casting machine's mold bridge frame structure has a small span and a reasonable force transmission path. It adopts an independent inward-retracting mold bridge support mechanism with a reasonable spatial layout, which can significantly shorten the minimum mold thickness and meet the needs of using more mold thicknesses.

[0007] Preferably, the retractable mold bridge support sliding mechanism includes a fixed mold bridge for mounting and supporting the fixed mold, a moving mold bridge for mounting and supporting the moving mold, and horizontally arranged dedicated mold bridge support slide rails. The retractable mold bridge support sliding mechanism mainly includes a fixed mold bridge for mounting the fixed mold, a moving mold bridge for mounting the moving mold, and dedicated mold bridge support slide rails for sliding the moving mold bridge. By setting independent dedicated mold bridge support slide rails, independent support for the mold bridge is achieved. The independent dedicated mold bridge support slide rails can effectively shorten the span of the mold bridge, improve structural rigidity, and avoid the problem of thermal deformation interference caused by the heat generated by the movement of the moving mold. The retractable mold bridge support slide rails can also make full use of space and are suitable for molds of various thicknesses.

[0008] Preferably, the fixed mold bridge is fixedly installed at one end of the mold bridge special support slide rail facing the fixed template, and the moving mold bridge is slidably disposed at one end of the mold bridge special support slide rail facing the moving template via a set of sliding blocks.

[0009] Preferably, the fixed mold bridge is equipped with a fixed mold bridge adjustment cylinder, and the moving mold bridge is equipped with a mold opening and closing cylinder. To meet the installation needs of molds of different thicknesses, the fixed mold bridge is equipped with a fixed mold bridge adjustment cylinder, which allows adjustment of the fixed mold bridge's position according to the mold thickness. The mold opening and closing cylinder on the moving mold bridge enables mold opening and closing operations during the die-casting process. Due to the use of an inward-retractable mold bridge support sliding mechanism, the fixed mold bridge adjustment cylinder and the mold opening and closing cylinder are also retracted into the lower interior of the fixed and moving mold plates, greatly saving space and making the structure more rational.

[0010] Preferably, the independent movable template sliding support mechanism includes template support sliding feet for mounting the movable template and independent movable template sliding foot support rails. The movable template sliding motion mechanism mainly includes template support sliding feet and independent movable template sliding foot support rails. Using independent movable template sliding foot support rails, the movable template is individually supported and guided to slide. The heat generated by friction during the movement of the movable template is not directly conducted to the mold bridge support surface and the frame surface, effectively avoiding thermal deformation interference. Simultaneously, the independent movable mold bridge sliding foot support rails and the retractable mold bridge dedicated support rails respectively bear the weight of the movable template and the mold, resulting in more even and reasonable force distribution.

[0011] Preferably, the template support sliding foot is slidably mounted on the moving template sliding foot support rail via a set of sliding foot sliders. The template support sliding foot is designed to facilitate the sliding of the moving template. Therefore, using sliding foot sliders to slidably connect the template support sliding foot to the moving template sliding foot support rail greatly facilitates the movement of the moving template.

[0012] Preferably, the mold bridge-specific support slide rail is recessed and positioned inside the movable template sliding foot support rail, and is slightly lower than the movable template sliding foot support rail. This recessed placement of the mold bridge-specific support slide rail inside the movable template sliding foot support rail results in a more rational structural design, independent load-bearing capacity, and more even stress distribution. The slightly lower position of the mold bridge-specific support slide rail compared to the movable template sliding foot support rail further optimizes the spatial layout, enabling the installation and use of molds of various sizes.

[0013] Preferably, the mold bridge frame body is provided with mold bridge support parts and template support parts arranged inside and outside. The arrangement of mold bridge support parts and template support parts on the mold bridge frame body facilitates the installation of dedicated mold bridge support rails and movable template sliding foot support rails.

[0014] Preferably, the mold bridge support is integrated into the mold bridge frame body. The mold bridge support can be integrated into the mold bridge frame body as a single unit.

[0015] Preferably, the mold bridge support is a separate component located inside the mold bridge frame body. Alternatively, the mold bridge support can also be a separate component located inside the mold bridge frame body; both configurations can accommodate the installation of a dedicated support slide rail for the mold bridge.

[0016] The beneficial effects of this utility model are as follows: By adopting an inward-retracting mold bridge support sliding mechanism and an independent moving template sliding support mechanism, a separate dual-support structure is set up, making the transmission path of the mold bridge and the moving template more reasonable. Because the dedicated support rail for the mold bridge and the sliding foot support rail of the moving template are designed separately and independently, the support span of the mold bridge is greatly shortened, effectively solving the problem of insufficient structural rigidity. During use, it can effectively reduce the vibration amplitude of the mold bridge, greatly improve the parallelism of the mold surface, enhance the rigidity of the mold bridge, reduce deformation, and make the frame more evenly stressed. It can make full use of space, and the minimum mold thickness is not limited by space, allowing compatibility with smaller mold sizes and meeting the die-casting needs of molds of different thicknesses. At the same time, it solves the problem of stress concentration; the heat generated by the friction of the moving template is not directly conducted to the mold bridge support surface and the frame surface, effectively avoiding thermal deformation interference.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Components not specifically described in the present invention are existing components or general components.

[0030] Example 1:

[0031] exist Figure 1 , Figure 2 In the embodiment shown, a die-casting machine mold bridge frame with a split support structure includes a mold bridge frame body 1, on which a split double-support sliding mechanism 2 is provided.

[0032] The mold bridge frame body 1 is an integrated structure, including a fixed template mounting end 11 and a movable template sliding end 12. A fixed template mounting part 13 is provided on the fixed template mounting end 11. The fixed template mounting part 13 extends on both sides of the mold bridge frame body 1 and is used to install and support the fixed template.

[0033] A mold bridge support 14 and a template support 15 are integrated on the mold bridge frame body 1 between the fixed template installation end 11 and the moving template sliding end 12. The mold bridge support 14 is located inside the template support 15.

[0034] The split double-support sliding mechanism 2 includes an inward-retracting mold bridge support sliding mechanism 3 and an independent moving template sliding support mechanism 4; the inward-retracting mold bridge support sliding mechanism 3 is separately arranged inside the independent moving template sliding support mechanism 4.

[0035] The retractable mold bridge support sliding mechanism 3 includes a fixed mold bridge 31 for mounting and supporting the fixed mold, a moving mold bridge 32 for mounting and supporting the moving mold, and a horizontally arranged mold bridge-specific support slide rail 33. The independent mold bridge-specific support slide rail 33 provides independent support for the mold bridge. This independent support slide rail effectively shortens the span of the mold bridge, improves structural rigidity, and avoids thermal deformation interference caused by heat generated during the movement of the moving mold. The retractable mold bridge-specific support slide rail also makes full use of space and is suitable for molds of various thicknesses.

[0036] The special support slide rail 33 for the mold bridge is horizontally arranged on the mold bridge support part 14.

[0037] The fixed mold bridge 31 is fixedly installed at one end of the mold bridge special support slide rail 33 facing the fixed template, and the moving mold bridge 32 is slidably disposed at one end of the mold bridge special support slide rail 33 facing the moving template via a set of sliding blocks 34.

[0038] The independent movable template sliding support mechanism 4 includes a template support sliding foot 41 for installing the movable template and an independent movable template sliding foot support rail 42. The movable template sliding foot support rail 42 is horizontally arranged on the template support part 15. The movable template sliding foot support rail 42 is located outside the mold bridge special support rail 33, which is arranged in an inward-recessed manner.

[0039] The template support sliding foot 41 is slidably mounted on the movable template sliding foot support rail 42 via a set of sliding foot sliders 43.

[0040] like Figure 3 , Figure 4 , Figure 5 As shown, in use, a fixed template 5 is installed on the template mounting part 13, and a movable template 6 is installed on the template support sliding foot 41. The fixed template 5 and the movable template 6 are connected by a set of tie rods 7. The movable template 6 and the template support sliding foot 41 slide on the movable template sliding foot support rail 42. The movable template sliding foot support rail 42 supports the movable template alone and bears the weight of the movable template.

[0041] The fixed mold of the die casting mold is set on the fixed mold bridge 31, and the moving mold of the die casting mold is set on the moving mold bridge 32. In use, the fixed mold and the fixed mold bridge, as well as the moving mold and the moving mold bridge, are supported and slid by the mold bridge special support slide rail 33. The mold bridge special support slide rail 33 bears the corresponding weight of the fixed mold and the fixed mold bridge, as well as the moving mold and the moving mold bridge.

[0042] By setting up dedicated support slide rails for mold bridges, the width between the two dedicated support slide rails is reduced to the inside of the sliding foot support rail of the moving template, making the distance between the two dedicated support slide rails for mold bridges smaller. The dedicated support slide rails for mold bridges adopt an inward-reducing design and have a smaller width, which can significantly shorten the minimum mold thickness of the die casting mold and adapt to more die casting mold thickness application scenarios.

[0043] Example 2:

[0044] exist Figure 6 , Figure 7 In the embodiment shown, a die-casting machine mold bridge frame with a split support structure includes a mold bridge frame body 1, on which a split double-support sliding mechanism 2 is provided.

[0045] In this embodiment, the mold bridge frame body 1 is generally a plate frame structure. A fixed template mounting end 11 and a movable template sliding end 12 are provided on the mold bridge frame body 1. A fixed template mounting part 13 is integrated on the fixed template mounting end 11, extending to both sides of the mold bridge frame body 1. A U-shaped support structure is formed between the fixed template mounting part and the fixed template mounting end, and the fixed template mounting part protrudes from the fixed template mounting end. The fixed template mounting part 13 is used to install and support the fixed template 5. The fixed template 5 is mounted on the fixed template mounting part 13, forming a drive stroke clearance space structure between the fixed template and the fixed template mounting end. This drive stroke clearance space structure is designed to facilitate the movement of the moving mold bridge drive mechanism. Through the reciprocating motion of the moving mold bridge drive mechanism, the moving template is driven to perform opening and closing mold movements.

[0046] A mold bridge support 14 and a template support 15 are integrated on the mold bridge frame body 1 between the fixed template mounting end 11 and the moving template sliding end 12. The mold bridge support 14 is located inside the template support 15. The mold bridge support 14 and the template support 15 are separately arranged on the mold bridge frame body, with the mold bridge support 14 independently built into the mold bridge frame body 1. The mold bridge support 14 is supported by a set of built-in support members 16. The template support 15 is located on the frame surface on both sides of the mold bridge frame body.

[0047] The aforementioned split-type double-support sliding mechanism 2 includes an inwardly recessed mold bridge support sliding mechanism 3 and an independent moving template sliding support mechanism 4, which are arranged in an inward and outward manner.

[0048] The retractable mold bridge support sliding mechanism 3 includes a fixed mold bridge 31 for mounting and supporting the fixed mold, a moving mold bridge 32 for mounting and supporting the moving mold, and a horizontally arranged mold bridge-specific support slide rail 33. In this embodiment, two fixed mold bridge adjusting cylinders 35 are horizontally arranged on the fixed mold bridge 31. The position of the fixed mold bridge can be adjusted by the two fixed mold bridge adjusting cylinders 35, so that the position of the fixed mold bridge can be adjusted according to the thickness of the mold to meet the support requirements of molds of different thicknesses. A mold opening and closing cylinder 36 is horizontally arranged on the moving mold bridge 32 for realizing the mold opening and closing operation.

[0049] The mold bridge special support slide rail 33 is horizontally set on the mold bridge support part 14, and the mold bridge special support slide rail 33 is slightly lower than the independent moving template sliding support mechanism 4, that is, the mold bridge special support slide rail 33 is slightly lower than the moving template sliding foot support rail 42. This structure facilitates the installation of molds and the sliding of moving templates. At the same time, it can make full use of space, making the overall design structure of the mold bridge frame body more reasonable. There will be no mutual interference during use, and the weight distribution of this design structure is more uniform.

[0050] The fixed mold bridge 31 is fixedly installed at one end of the mold bridge special support slide rail 33 facing the fixed template, and the moving mold bridge 32 is slidably disposed at one end of the mold bridge special support slide rail 33 facing the moving template via a set of sliding blocks 34.

[0051] The independent movable template sliding support mechanism 4 includes a template support sliding foot 41 for installing the movable template and an independent movable template sliding foot support rail 42. The movable template sliding foot support rail 42 is horizontally arranged on the template support part 15. The movable template sliding foot support rail 42 is located outside the mold bridge special support slide rail 33, which is inwardly recessed, and the movable template sliding foot support rail 42 is slightly higher than the mold bridge special support slide rail 33.

[0052] The template support sliding foot 41 is slidably mounted on the movable template sliding foot support rail 42 via a set of sliding foot sliders 43.

[0053] In use, a fixed template 5 is installed on the template installation part 13, and a movable template 6 is installed on the template support sliding foot 41. The fixed template 5 and the movable template 6 are connected by a set of tie rods 7. The movable template 6 and the template support sliding foot 41 slide on the movable template sliding foot support rail 42. The movable template sliding foot support rail 42 supports the movable template alone and bears the weight of the movable template.

[0054] The fixed mold of the die casting mold is set on the fixed mold bridge 31, and the moving mold of the die casting mold is set on the moving mold bridge 32. In use, the fixed mold and the fixed mold bridge, as well as the moving mold and the moving mold bridge, are supported and slid by the mold bridge special support slide rail 33. The mold bridge special support slide rail 33 bears the corresponding weight of the fixed mold and the fixed mold bridge, as well as the moving mold and the moving mold bridge.

[0055] By setting up dedicated support slide rails for mold bridges, the width between the two dedicated support slide rails is reduced to the inside of the sliding foot support rail of the moving template, making the distance between the two dedicated support slide rails for mold bridges smaller. The dedicated support slide rails for mold bridges adopt an inward-reducing design and have a smaller width, which can significantly shorten the minimum mold thickness of the die casting mold and adapt to more die casting mold thickness application scenarios.

[0056] The die-casting machine mold bridge frame with a split support structure described in the above embodiments uses a separate dual-support structure for the inward-retracting mold bridge support sliding mechanism 3 and the independent moving template sliding support mechanism 4. This makes the transmission path of the mold bridge and the moving template more reasonable. The dedicated mold bridge support rail and the independent moving template sliding foot support rail can each bear a portion of the weight. Because the dedicated mold bridge support rail and the moving template sliding foot support rail are designed separately and independently, the vibration amplitude of the mold bridge can be effectively reduced during use. The vibration amplitude of the mold bridge can be reduced by 60%, the parallelism of the mold surface is greatly improved, the rigidity of the mold bridge is increased and deformation is reduced, the frame is more evenly stressed, it can be compatible with smaller mold sizes, the amount of material used in the frame design is reduced, and the maintenance cycle is extended to 6000 hours.

[0057] In existing technologies, the mold bridge and template slide share the same frame support rail, resulting in an excessively large support span. Under the action of large molds in large machines, the deflection in the middle of the mold bridge can reach over 0.3 mm / m, leading to insufficient structural rigidity. This die-casting machine mold bridge frame with a split support structure adopts a design where the dedicated support rail for the mold bridge and the support rail for the moving template slide are separate. This significantly shortens the support span of the mold bridge, effectively solving the problem of insufficient structural rigidity.

[0058] In existing technologies, the mold bridge and moving template share a common support structure, resulting in low space utilization. Furthermore, the shared support structure requires space for the sliding foot movement and the mold bridge thickness itself, thus limiting the minimum mold thickness. This die-casting machine mold bridge frame with a split support structure employs a separate design for the mold bridge's dedicated support rail and the moving template's sliding foot support rail. This design maximizes space utilization, eliminating space limitations on the minimum mold thickness and meeting the die-casting needs of molds with varying thicknesses.

[0059] In existing technologies, a shared support structure is used, which concentrates the weight of the frame on a single support rail, easily causing excessive local deformation of the guide rail. The die-casting machine mold bridge frame with a split support structure adopts a design that separates the mold bridge-specific support rail from the sliding foot support rail of the moving template, thus solving the problem of concentrated stress.

[0060] In existing technologies, a common support structure is used, and the heat (up to 80°C) generated by the sliding friction of the moving template is directly conducted to the mold bridge support surface and the frame surface, causing thermal deformation interference. The die casting machine mold bridge frame with a split support structure adopts a design that separates the mold bridge dedicated support rail from the moving template sliding foot support rail. The heat generated by the sliding friction of the moving template will not be directly conducted to the mold bridge support surface and the frame surface, which can effectively avoid thermal deformation interference.

[0061] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
