Description

Technical Field

[0001] This invention relates to the field of mold clamping machines, specifically a high-precision large-scale mold clamping machine. Background Technology

[0002] Mold clamping machines are a type of large-scale equipment commonly used in die casting production units. With the rapid development of new energy vehicles, more and more new energy vehicles are adopting integrated vehicle chassis, which requires larger die casting molds. In order to meet the mold clamping adaptation needs of large die casting molds, large mold clamping machines are also needed, such as mold clamping machines with a capacity of over 1,000 tons. For mold clamping machines with a capacity of over 1,000 tons, the length and width of the lower mold base exceed those of conventional mold clamping machines. During the process of the lower mold base moving and positioning under the mold clamping machine, deformation is likely to occur. Deformation of the lower mold base will cause deformation or displacement of the mold, which will damage the mold or affect the normal repair of the mold. Summary of the Invention

[0003] This invention provides a large mold clamping machine that can solve the problem that the lower mold base of existing large mold clamping machines is prone to deformation during use.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a large mold clamping machine, comprising a base, four guide pillars vertically arranged on the upper side of the base, a top seat mounted on the top of the guide pillars, a middle seat that moves up and down along the guide pillars between the base and the top seat, a plurality of lifting cylinders connected to the middle seat mounted on the top seat, a tilting template rotatably connected to the front side of the middle seat, at least two tilting cylinders connected to the tilting template mounted on the upper side of the middle seat, a plurality of supporting cylinders for supporting the lifting of the middle seat mounted on the side of the base, and a side movable support frame arranged side by side on the front side of the base; a central movable support frame arranged in the middle of the front side of the base and parallel to the side movable support frame, guide rails extending to the rear edge of the base are laid on the upper side of both the central movable support frame and the side movable support frame, and a lower mold seat is rolled and translated on the upper side of the guide rails; the upper edge of the base... The base has at least two first mounting holes on the guide rails on both sides, in which a mold base side support assembly is installed. A second mounting hole is located at the center of the base, corresponding to the position of the guide rail in the middle, in which a mold base middle support assembly is installed. The rollers on the lower side of the lower mold base correspond to the positions of the mold base side support assembly and the mold base middle support assembly. Movable cylinder support seats are arranged side-by-side on both the front and rear sides of the base. Support roller seats corresponding to the movable cylinder support seats are arranged on both the front and rear sides of the lower mold base. The lower mold base is supported by both the middle and side movable support frames to prevent deformation during translation. Furthermore, during the lifting and lowering process after the lower mold base moves to the base position, the mold base side support assembly, the mold base middle support assembly, the movable cylinder support seats, and the support roller seats lift the lower mold base, effectively preventing deformation during lifting and lowering.

[0005] Preferably, the upper side of the base is provided with at least two guide seats close to the guide rails on both sides, and the side wall of the lower mold base is provided with a guide plate that matches the guide seats. The guide seats include a raised seat and a guide wheel limiting seat provided on the upper side of the raised seat. A guide wheel that contacts the guide plate is horizontally installed on the guide wheel limiting seat. The guide wheel can ensure that the lower mold base moves into place and will not detach from the guide rails.

[0006] Preferably, the guide wheel is a metal guide wheel. When the guide wheel contacts the guide plate, it generates a conduction signal and transmits it to the control unit of the mold clamping machine. This can monitor whether the lower mold base has moved into place and provide a signal for subsequent lifting and lowering to prevent damage to the lower mold base.

[0007] Preferably, mounting ears are provided on the front and rear sides of the base corresponding to the positions of the movable cylinder support. The movable cylinder support includes a movable seat and a lifting cylinder disposed on the top of the movable seat. The mounting ears are embedded in the movable seat and connected to the movable seat through a rotating component. The mounting ears enable quick installation of the movable seat, and the movable seat can rotate within a certain angle range. In this way, if the supporting roller seat is not accurately positioned when the lifting cylinder lifts it, it can adjust its angle to ensure effective lifting of the supporting roller seat. Moreover, since the mounting ears are embedded in the movable seat and the rotating component is installed, no other fasteners are required, making the installation very simple and reliable.

[0008] Preferably, the supporting roller seat includes a supporting base, and a supporting roller is mounted on the lower part of the supporting base via a rotating shaft. The supporting roller is in contact with the lifting cylinder. The supporting base is rotatably connected to the side wall of the lower mold base via a plug shaft. Horizontally adjustable limiting blocks are provided on the side walls of the lower mold base on both sides of the supporting base. The supporting roller can slide a short distance on the surface of the lifting cylinder by rotating. The supporting base can rotate at a small angle to ensure that the supporting roller can fully contact the lifting cylinder. The limiting blocks can be adjusted to change the adjustment angle of the supporting base.

[0009] Preferably, the base is provided with diagonal bracing brackets arranged side by side on the front side. The upper end of the diagonal bracing brackets is fixedly connected to the top seat. By setting two diagonal bracing brackets, the top seat can be reinforced, and no large swing will occur when the flipping template on the top seat flips forward.

[0010] Preferably, the upper width of the diagonal brace is smaller than the lower width, and several interconnected horizontal and vertical reinforcing plates are provided on both sides of the diagonal brace. This can improve the strength of the diagonal brace and make the support more stable.

[0011] Preferably, a limiting abutment device is installed on the upper side of the middle seat, located behind the tilting cylinder. The limiting abutment device includes a support column, an upper inclined brace located on the upper side of the support column and extending towards the tilting cylinder, and a lower inclined brace located on the rear side of the support column and extending diagonally downward to abut against the side wall of the middle seat. A cylinder backing plate is installed at the front end of the upper inclined brace. The entire limiting abutment device can be installed through the support column. The upper and lower inclined braces allow the tilting cylinder to act on the middle seat when tilted, thus providing abutment.

[0012] Preferably, a pair of threaded sleeves are arranged side by side at the front end of the upper inclined support, and a support screw is inserted inside the threaded sleeve. The end of the support screw is connected to the cylinder support plate, and a locking nut is fitted on the support screw. The position of the cylinder support plate can be adjusted by the support screw, thereby adjusting the position of the support point. The locking nut can lock the position of the support screw and prevent the support screw from moving axially.

[0013] Preferably, a first mounting plate is provided on the upper rear side of the supporting column. The first mounting plate is connected to one end of the lower inclined brace by fasteners. A base plate is installed at the bottom of the lower inclined brace, and the base plate is close to the top surface of the middle seat. A second mounting plate is provided perpendicularly to one side of the base plate. The second mounting plate is connected to the side wall of the middle seat by fasteners. The first mounting plate can realize a firm connection between the lower inclined brace and the supporting column, and the second mounting plate can ensure a firm connection between the lower inclined brace and the side wall of the middle seat.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] (1) Improve the existing double-stage support mold clamping machine by using three guide rails to support the lower mold base, and by setting multiple side support components and middle support components of the mold base to support the lower mold base at multiple points so that the lower mold base can descend synchronously. Also, install matching movable hydraulic cylinder support seats and support roller seats on the front and rear sides to provide auxiliary support for the lower mold base when it rises, prevent the lower mold base from deforming, and meet the usage requirements of large mold clamping machines.

[0016] (2) By setting two inclined support brackets, the top seat can be reinforced. When the mold on the top seat flips forward, it will not swing too much. It has obvious effect on the application of large mold clamping machines and has good promotion value.

[0017] (3) A limit contact device is installed on the middle seat. The entire limit contact device can be installed through the support column. The upper and lower inclined braces can act on the middle seat when the tilting cylinder is tilted, thus playing a contact role. This can solve the technical problem that the existing large mold closing machine's tilting cylinder has no support and cannot reliably support the template tilting. Attached Figure Description

Detailed Implementation

[0031] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0032] This invention addresses the problem of deformation of the lower mold base in existing large mold clamping machines during translation. Specifically, for large mold clamping machines exceeding 1000 tons, the lateral span of the lower mold base exceeds 6 meters, and the longitudinal span in the front-to-back direction exceeds 4 meters. During use, the lower mold base moves to the base of the mold clamping machine and is then lowered and mounted on the base to prepare for subsequent mold clamping. However, during the lifting and lowering of the lower mold base, due to the large weight and lateral span of the mold mounted on it, deformation is easily caused.

[0033] To solve the above technical problems, such as Figure 1-11 As shown, the following technical solution is provided: A large mold clamping machine includes a base 1, four guide pillars 2 vertically arranged on the upper side of the base 1, a top seat 4 installed on the top of the guide pillars 2, a middle seat 3 that moves up and down along the guide pillars 2 between the base 1 and the top seat 4, a plurality of lifting cylinders 6 connected to the middle seat 3 being arranged on the top seat 4, a flipping template 10 rotatably connected to the front side of the middle seat 3, and at least two flipping cylinders 5 connected to the flipping template 10 being arranged on the upper side of the middle seat 3. The base 1 has multiple supporting cylinders 11 installed on its side to support the lifting and lowering of the middle base 3, and also includes a side movable support frame 12, which is arranged side by side on the front side of the base 1; a middle movable support frame 8 is located in the middle of the front side of the base 1 and is parallel to the side movable support frame 12. The upper sides of both the middle movable support frame 8 and the side movable support frame 12 are covered with guide rails 16 extending to the rear edge of the base 1. A lower mold base 9 is rolled and translated on the upper side of the guide rails 16; the base 1 has guide rails on both sides. The base 16 is provided with at least two first mounting holes 14, in which a mold base side support assembly 15 is installed. A second mounting hole is provided at the center of the base 1, corresponding to the guide rail 16 in the middle, in which a mold base middle support assembly 13 is installed. The rollers on the lower side of the lower mold base 9 correspond to the positions of the mold base side support assembly 15 and the mold base middle support assembly 13. Movable hydraulic cylinder support seats 19 are arranged side-by-side on both the front and rear sides of the base 1. The lower mold base 9... The front and rear sides are provided with supporting roller seats 18 corresponding to the movable cylinder support seat 19. The lower mold base 9 is supported by the central movable support frame 8 and the side movable support frame 12 to prevent the lower mold base 9 from deforming during translation. At the same time, after the lower mold base 9 moves to the position of the base 1, the lower mold base 9 is supported by the mold base side support assembly 15, the mold base central support assembly 13, the movable cylinder support seat 19 and the supporting roller seats 18 during the lifting process, which can effectively prevent the lower mold base 9 from deforming during the lifting process.

[0034] The mold clamping machine in this embodiment is a double-stage support mold clamping machine. In the upper half of the lifting stroke of the middle seat 3, the lifting cylinder 6 drives the lifting. When the lifting cylinder 6 extends to the limit position, the support cylinder 11 rises to support the middle seat 3, and the lifting cylinder 6 separates from the middle seat 3. The support cylinder 11 can make the middle seat 3 continue to descend to achieve mold clamping. This structure allows the length of the lifting cylinder 6 to be relatively short, reducing the height of the entire mold clamping machine.

[0035] Specifically, the lower mold base 9 can be driven to move by a transmission chain installed on the central movable support frame 8. During mold repair, the lower mold base 9 can be moved to the front end of the central movable support frame 8 and the side movable support frame 12. During mold closing, the lower mold base 9 moves to the upper side of the base 1, corresponding to the position of the flip template 10 on the lower side of the central base 3. After the lower mold base 9 moves to the upper side of the base 1, the lower mold base 9 can be supported by the mold base side lifting assembly 15 and the mold base central lifting assembly 13 at the same time, so that it descends until the bottom is in contact with the base 1. In this way, the mold on the upper side of the lower mold base 9 can be closed.

[0036] After the mold is closed, the lower mold base 9 needs to move outward, which requires lifting the lower mold base 9. If only the side support assembly 15 and the middle support assembly 13 of the mold base apply an upward force to the lower mold base 9, the lower mold base 9 is prone to deformation at the moment of upward lifting. Therefore, the movable cylinder support seat 19 and the support roller seat 18 on the front and rear sides are used to provide auxiliary support for the lower mold base 9. The movable cylinder support seat 19 and the support roller seat 18 are located in the area between the side support assembly 15 and the middle support assembly 13 of the mold base. Therefore, they are lifted simultaneously with the side support assembly 15 and the middle support assembly 13 of the mold base to prevent the lower mold base 9 from deforming.

[0037] In this embodiment, as Figure 4-5 As shown, at least two guide seats 21 are provided on the upper side of the base 1, close to the guide rails 16 on both sides. The side wall of the lower mold base 9 is provided with guide plates 31 that mate with the guide seats 21. Each guide seat 21 includes a raised seat 33 and a guide wheel limiting seat 32 located on the upper side of the raised seat 33. Guide wheels 34, which contact the guide plates 31, are horizontally mounted on the guide wheel limiting seat 32. The guide wheels 34 ensure that the lower mold base 9 moves into position and does not detach from the guide rails 16. Simultaneously, the guide wheels 24 are metal guide wheels. When the guide wheels 34 contact the guide plates 31, they generate a conduction signal and transmit it to the control unit of the mold clamping machine. This allows monitoring of whether the lower mold base 9 has moved into position, providing signals for subsequent lifting and lowering. Specifically, only when all guide wheels 34 contact the guide plates 31 to form a circuit does it indicate that the lower mold base 9 has moved into position, allowing for lifting and lowering operations to prevent safety accidents.

[0038] In this embodiment, as Figure 6-8 As shown, mounting ears 17 are provided on the front and rear sides of the base 1 at positions corresponding to the movable cylinder support 19. The movable cylinder support 19 includes a movable seat 52 and a lifting cylinder 51 disposed on the top of the movable seat 52. The mounting ears 17 are embedded in the movable seat 52 and connected to the movable seat 52 through a rotating component 53. The mounting ears 17 enable quick installation of the movable seat 52, and the movable seat 52 can rotate within a certain angle range. Thus, when the lifting cylinder 51 lifts the support roller seat 18, if the support roller seat 18 is not accurately positioned, it can adjust its angle to ensure effective lifting of the support roller seat 18. Furthermore, since the mounting ears 17 are embedded in the movable seat 52 and the rotating component 53 is installed, no other fasteners are required, making the installation very simple and reliable.

[0039] In this embodiment, as Figure 6-8 As shown, the supporting roller seat 18 includes a supporting seat 42. The lower part of the supporting seat 42 is equipped with a supporting roller 41 via a rotating shaft 43. The supporting roller 41 is in contact with the lifting cylinder 51. The supporting seat 42 is rotatably connected to the side wall of the lower mold seat 9 via a plug shaft 44. The side walls of the lower mold seat 9 on both sides of the supporting seat 42 are provided with horizontally adjustable limiting blocks 45. The supporting roller 31 can slide a short distance on the surface of the lifting cylinder 51 by rotating, while the supporting seat 42 can rotate at a small angle so that the supporting roller 41 can fully contact the lifting cylinder 51. The limiting blocks 45 can be adjusted to change the adjustment angle of the supporting seat 42.

[0040] When using a mold clamping machine to repair a mold, the tilting platen 10 needs to be tilted forward. Due to the heavy weight of the mold, the top seat of the mold clamping machine swings significantly during the tilting process, posing a risk of overturning. To solve this problem, such as... Figure 1-2 As shown, the base 1 has two diagonal bracing supports 7 arranged side by side on its front side. The upper end of the diagonal bracing support 7 is fixedly connected to the top seat 4. By setting two diagonal bracing supports 7, the top seat 4 can be reinforced. When the flipping template 10 on the top seat 4 flips forward, it will not produce a large swing. The upper width of the diagonal bracing support 7 is smaller than the lower width. Several interconnected horizontal reinforcing plates and vertical reinforcing plates are set on both sides of the diagonal bracing support 7. This can improve the strength of the diagonal bracing support 7 and make the support more stable.

[0041] Furthermore, when the flipping template 10 is in the flipped state, if the flipping cylinder 5 is not supported by a support structure, the rotating shaft is prone to deformation, and the support of the flipping cylinder 5 for the template cannot be stable, which may lead to an accident. To solve this problem, such as Figure 9-11As shown, a limiting abutment device is installed on the upper side of the middle seat 3, located behind the tilting cylinder 5. The limiting abutment device includes a support column 66, an upper inclined brace 62 located on the upper side of the support column 66 and extending towards the tilting cylinder 5, and a lower inclined brace 61 located on the rear side of the support column 66 and extending diagonally downward to abut against the side wall of the middle seat 3. A cylinder backing plate 64 is installed at the front end of the upper inclined brace 62. The entire limiting abutment device can be installed through the support column 66. The upper inclined brace 62 and the lower inclined brace 61 can act on the middle seat when the tilting cylinder 5 is tilted, thus providing abutment.

[0042] In this embodiment, a pair of threaded sleeves 69 are arranged side by side at the front end of the upper inclined support 62. A support screw 63 is inserted into the threaded sleeve 69. The end of the support screw 63 is connected to the cylinder support plate 64. A locking nut 71 is sleeved on the support screw 63. The position of the cylinder support plate 64 can be adjusted by the support screw 63, thereby adjusting the position of the support point. The locking nut 71 can lock the position of the support screw and prevent the support screw 63 from moving axially.

[0043] At the same time, such as Figure 9 As shown, a first mounting plate 65 is provided on the upper rear side of the supporting column 66. The first mounting plate 65 is connected to one end of the lower inclined brace 61 by fasteners. A base plate 67 is installed at the bottom of the lower inclined brace 61. The base plate 67 is close to the top surface of the middle seat 3. A second mounting plate 68 is provided perpendicularly to one side of the base plate 67. The second mounting plate 68 is connected to the side wall of the middle seat 3 by fasteners. The first mounting plate 65 can realize the firm connection between the lower inclined brace and the supporting column, and the second mounting plate 68 can ensure the firm connection between the lower inclined brace 61 and the side wall of the middle seat 3.

[0044] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indication will also change accordingly.

[0045] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0046] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0047] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
