Description

Technical Field

[0001] This application relates to the field of mold technology, specifically a mold support. Background Technology

[0002] Mold supports are indispensable support and positioning components in mold systems. They mainly bear the weight of the mold, provide a stable mounting base for the mold, and ensure that the mold maintains an accurate position and posture during operation. In industrial production, mold supports are like bridge piers, tightly connecting the mold to molding equipment (such as stamping machines, injection molding machines, etc.). They are a key link in ensuring the normal operation of the mold and improving production stability. Mold supports need to have sufficient load-bearing capacity to cope with the weight of the mold itself and the various forces generated during the molding process, preventing deformation or displacement due to excessive force, which would affect the molding accuracy of the mold.

[0003] Some existing mold supports use bolt connections to install the mold. Operators need to hoist the mold onto the support and ensure that the bolt holes on the mold are precisely aligned with the bolt holes on the support. This alignment process requires repeated adjustments and is very time-consuming. After alignment, bolts are inserted one by one and manually pre-tightened. During the tightening process, the horizontal and vertical alignment of the mold needs to be checked. If any deviation is found, the bolts need to be loosened and readjusted, which increases the labor intensity of the operators.

[0004] Therefore, it is necessary to provide a mold support to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0031] like Figure 1-2 As shown, this application provides a mold support, including a base 1 and a mounting plate 3. The base 1 and mounting plate 3 are typically forged from high-strength alloy steel, possessing excellent compressive and deformation resistance, and capable of withstanding the enormous pressure generated by the mold during the molding process. The base 1 is mounted on the worktable of the molding equipment. As the basic load-bearing component of the entire support, it needs to have sufficient rigidity to support all the components above it, ensuring that the mold does not shake or shift during operation.

[0032] Mounting plate 3 serves as the top support platform, located at the top of base 1. Guide rods 6 are fixedly installed at the four corners of the upper part of base 1. Mounting plate 3 is slidably connected to guide rods 6. Guide rods 6 are made of high carbon steel with chrome plating, which is not only smooth and wear-resistant, but also provides precise guidance for the up and down movement of mounting plate 3, allowing mounting plate 3 to move stably up and down along guide rods 6, facilitating mold closing and opening operations.

[0033] like Figure 3-5As shown, a quick-locking assembly 5 is provided on the base 1 and the mounting plate 3. The quick-locking assembly 5 includes a first limiting plate 51 and a second limiting plate 55, which are respectively fixedly installed on both sides of the base 1 and the mounting plate 3. The first limiting plate 51 and the second limiting plate 55 are made of thick-walled steel plates and are connected to the base 1 and the mounting plate 3 by bolts, ensuring sufficient strength to support the operation of the hydraulic cylinder.

[0034] A first hydraulic cylinder 52 is fixedly installed on one side of the two first limiting plates 51 by bolts. The output end of the first hydraulic cylinder 52 passes through the first limiting plate 51 and is then welded and fixedly installed with a first push plate 53. A first clamping plate 54 is fixedly installed on one side of the first push plate 53 by bolts. This detachable connection method facilitates the replacement and maintenance of the first clamping plate 54.

[0035] Both sides of the upper mold 4 are provided with first slots 59 that are adapted to the first card plate 54. The first card plate 54 is engaged in the first slots 59. Through this mechanical engagement, the upper mold 4 can be reliably locked and installed, preventing the upper mold 4 from shifting during operation.

[0036] Similarly, a second hydraulic cylinder 56 is fixedly installed on one side of the two second limiting plates 55 by bolts. The output end of the second hydraulic cylinder 56 passes through the second limiting plate 55 and is welded and fixedly installed with a second push plate 57. A second clamping plate 58 is fixedly installed on one side of the second push plate 57 by bolts. A second clamping groove 510 adapted to the second clamping plate 58 is opened on both sides of the lower mold 2. The second clamping plate 58 is clamped in the second clamping groove 510 to achieve the locking installation of the lower mold 2.

[0037] Rubber pads (not shown in the figure) are fixedly installed on one side of the first card plate 54 and the second card plate 58. The rubber pads have good elasticity and wear resistance. When the first card plate 54 and the second card plate 58 are engaged with the first card slot 59 and the second card slot 510, they can play a buffering role, reduce the impact force during the engagement process, and increase the friction between the first card plate 54 and the second card plate 58 and the first card slot 59 and the second card slot 510, thereby improving the reliability of locking. They also avoid direct contact between metals and prevent the first card plate 54 and the second card plate 58 and the first card slot 59 and the second card slot 510 from being worn.

[0038] The first hydraulic cylinder 52 and the second hydraulic cylinder 56 are both controlled by an external hydraulic system. In order to ensure the synchronization of the four hydraulic cylinders, a flow divider and combiner valve (not marked in the figure) is connected in series on the oil inlet lines of the two first hydraulic cylinders 52 and the two second hydraulic cylinders 56. The flow divider and combiner valve can effectively distribute the flow of hydraulic oil, ensuring that the flow deviation entering each cylinder is ≤5%, so that the extension speed of the four cylinders is consistent.

[0039] In addition, each hydraulic cylinder is equipped with a displacement sensor (not shown in the figure) and a proportional flow valve (not shown in the figure). The displacement sensor can monitor the extension and retraction stroke of the hydraulic cylinder in real time and transmit the signal to the PLC. The PLC compares the strokes of the four cylinders in real time and dynamically adjusts the opening of each proportional flow valve according to the stroke deviation to achieve closed-loop synchronous control, which further improves the synchronization accuracy of the hydraulic cylinder action and ensures the accuracy and reliability of locking the upper mold 4 and the lower mold 2.

[0040] like Figure 2-5 As shown, in terms of the initial installation and positioning of the mold, a first guide rail 7 is fixedly installed in the middle of the lower end of the mounting plate 3, and first limiting blocks 8 are fixedly installed on both sides of the lower end of the mounting plate 3. A first sliding groove 12 is opened in the middle of the upper end of the upper mold 4, and a first limiting groove 10 is opened on both sides of the upper end of the upper mold 4. The first guide rail 7 is slidably connected to the first sliding groove 12, and the first limiting block 8 is slidably connected to the first limiting groove 10. This double guiding and limiting structure can ensure that the upper mold 4 slides along a precise trajectory at the lower end of the mounting plate 3, avoiding deviation.

[0041] Both sides of the rear end of the mounting plate 3 are fixedly equipped with first baffles 13. The first baffles 13 are made of wear-resistant steel plates and are used to initially limit the installation position of the upper mold 4, preventing the upper mold 4 from sliding excessively backward and ensuring the accuracy of the installation position. Each of the two first baffles 13 is equipped with a first limiting bolt 14. The two first limiting bolts 14 pass through the first baffles 13 and are threadedly connected to the upper mold 4. By adjusting the first limiting bolts 14, the position of the upper mold 4 can be locked to ensure the accuracy of the installation of the upper mold 4.

[0042] First positioning plates 15 are fixedly installed on both sides of the front end of the upper mold 4. First positioning bolts 16 are provided on the two first positioning plates 15. The two first positioning bolts 16 pass through the first positioning plates 15 and are threadedly connected to the mounting plate 3 to further limit the installation of the upper mold 4, so that the upper mold 4 is firmly fixed in the front and rear directions, ensuring the stability of the upper mold 4 during operation. First guide posts 9 are fixedly installed on the two first positioning plates 15. Two first guide holes 11 are opened inside the upper mold 4. The first guide posts 9 are slidably connected to the first guide holes 11 to improve the stability of the upper mold 4 during installation.

[0043] For the installation and positioning of the lower mold 2, a second guide rail 18 is fixedly installed in the middle of the upper end of the base 1, and a second limiting block 17 is fixedly installed on both sides of the upper end of the base 1. A second sliding groove 21 is opened in the middle of the lower end of the lower mold 2, and a second limiting groove 20 is opened on both sides of the lower end of the lower mold 2. The second guide rail 18 is slidably connected to the second sliding groove 21, and the second limiting block 17 is slidably connected to the second limiting groove 20.

[0044] The base 1 has two second baffles 23 fixedly installed on both sides of the rear end, which are used to initially limit the installation position of the lower mold 2. The two second baffles 23 are provided with second limiting bolts 24. The two second limiting bolts 24 pass through the second baffles 23 and are threadedly connected to the lower mold 2, which can fix the position of the lower mold 2.

[0045] The lower mold 2 has two fixedly installed second positioning plates 25 on both sides of its front end. The two second positioning plates 25 are provided with second positioning bolts 26. The two second positioning bolts 26 pass through the second positioning plates 25 and are threaded to the base 1 to fix the lower mold 2, ensuring that the lower mold 2 will not be displaced during operation and guaranteeing the accuracy of mold forming. The two second positioning plates 25 are fixedly installed with second guide posts 19. The lower mold 2 has two second guide holes 22 inside. The second guide posts 19 are slidably connected to the second guide holes 22 to improve the stability of the lower mold 2 installation.

[0046] Working principle: The first stage is the mold installation stage. For the upper mold 4, align the first sliding groove 12 at the upper end of the upper mold 4 with the first guide rail 7 at the lower middle of the mounting plate 3, and at the same time align the first limiting grooves 10 on both sides of the upper end of the upper mold 4 with the first limiting blocks 8 on both sides of the lower end of the mounting plate 3. Then push the upper mold 4 to slide backward along the first guide rail 7 and the first limiting blocks 8 until the rear end of the upper mold 4 contacts the first baffles 13 on both sides of the rear end of the mounting plate 3, completing the initial limiting.

[0047] Next, adjust the first limiting bolt 14 on the first baffle 13 so that it passes through the first baffle 13 and is threadedly connected to the upper mold 4, locking the front and rear positions of the upper mold 4. Then, through the first positioning bolts 16 on the first positioning plates 15 on both sides of the front end of the upper mold 4, let them pass through the first positioning plates 15 and be threadedly connected to the mounting plate 3, further fixing the upper mold 4 and ensuring that it is stably installed at the lower end of the mounting plate 3.

[0048] For the lower mold 2, align the second slide groove 21 at the lower end of the lower mold 2 with the second guide rail 18 at the middle of the upper end of the base 1, align the second limiting grooves 20 on both sides of the lower end of the lower mold 2 with the second limiting blocks 17 on both sides of the upper end of the base 1, and push the lower mold 2 to slide backward until it contacts the second baffles 23 on both sides of the rear end of the base 1.

[0049] Subsequently, the second limiting bolt 24 on the second baffle 23 is adjusted to make it threadedly connected to the lower mold 2, and then the second positioning bolt 26 on the second positioning plates 25 on both sides of the front end of the lower mold 2 is threadedly connected to the base 1 to complete the fixed installation of the lower mold 2.

[0050] After the mold is installed, a locking operation is performed. The first hydraulic cylinder 52 and the second hydraulic cylinder 56 are controlled by an external hydraulic system. In the oil inlet lines of the two first hydraulic cylinders 52 and the two second hydraulic cylinders 56, a series-connected flow divider and combiner valve distributes the hydraulic oil flow, ensuring that the flow deviation entering each cylinder is ≤5%, thus making the extension speed of the four cylinders consistent. Simultaneously, displacement sensors on the hydraulic cylinders monitor the extension and retraction stroke in real time and transmit the signal to the PLC. After comparing the strokes of the four cylinders, the PLC dynamically adjusts the opening of each proportional flow valve according to the deviation, achieving closed-loop synchronous control.

[0051] Driven by the hydraulic cylinders, the output end of the first hydraulic cylinder 52 moves the first push plate 53 and the first clamping plate 54, causing the first clamping plate 54 to engage with the first clamping slots 59 on both sides of the upper mold 4; the output end of the second hydraulic cylinder 56 moves the second push plate 57 and the second clamping plate 58, causing the second clamping plate 58 to engage with the second clamping slots 510 on both sides of the lower mold 2. At this time, the rubber pads on one side of the first clamping plate 54 and the second clamping plate 58 will play a buffering role, reducing the impact force, increasing the friction force, and avoiding direct metal-to-metal contact that could lead to wear, thereby reliably locking the upper and lower molds 2.

[0052] When mold closing and opening operations are required, the mounting plate 3 will move steadily up and down along the guide rods 6 at the four corners of the upper end of the base 1. The guide rods 6 are chrome-plated, smooth and wear-resistant, ensuring the precise guidance of the mounting plate 3 and facilitating the smooth completion of mold closing and opening operations.

[0053] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
