Description

Technical Field

[0001] This application relates to the field of die casting machine technology, and in particular to a testing system for moving parts of a die casting machine. Background Technology

[0002] The toggle mechanism of a die-casting machine is a core component of the mold-closing system. The toggle mechanism mainly consists of a crosshead and a connecting rod assembly. The crosshead connects to the piston end of the mold-closing cylinder, and through the connecting rod assembly, it connects to the head plate and the moving mold. The mold-closing cylinder uses the toggle mechanism to perform the mold-closing, locking, and opening actions of the moving mold. Before assembling the connecting rod assembly with the die-casting machine's crosshead, it needs to be tested to ensure proper operation after assembly and to avoid production accidents caused by component quality issues.

[0003] like Figure 1 The diagram shown is a structural schematic of the moving parts of a linkage assembly. Figure 2 As shown, link assembly 1 is installed in the test system for testing. Figure 3 As shown, the existing linkage assembly 1 is installed in the testing system according to the following principle: First, the end of the linkage assembly 1 is inserted into the hinge seat 4 of the testing system. Then, the pin 7 passes through both the hinge seat 4 and the linkage assembly 1. Next, the retaining plate 5 is inserted into the corresponding slot 6. Finally, the retaining plate 5 is tightened with bolts to lock the pin 7, thus achieving the installation of the end of the linkage assembly 1. This connection method is cumbersome and time-consuming, affecting testing efficiency. In addition, different models of retaining plates 5 and bolts are easily confused or lost after disassembly. Therefore, how to improve the installation structure of the linkage assembly in the existing testing system to overcome the above problems is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: a testing system for moving parts of a die-casting machine, comprising a hinge seat, a pin, a pair of limiting members, a driving member, and a transmission assembly. The hinge seat includes a base body and a pair of ear plates connected to the base body. The two ear plates cooperate with the ends of a connecting rod assembly to be tested. The pin passes through the ear plates and the ends of the connecting rod assembly. The limiting members are rotatably disposed on the sides corresponding to the ear plates. The driving member is installed in the base body. The transmission assembly is disposed in the base body and its input end is connected to the driving member. The output end of the transmission assembly is connected to the limiting members. When the pin is locked, the driving member is adapted to drive the limiting members to rotate relative to each other and move closer to each other until they abut against the limiting grooves at both ends of the pin through the transmission assembly. When the pin is unlocked, the driving member is adapted to reverse and retract closer to the base body.

[0009] Preferably, the die-casting machine moving parts testing system further includes a transmission device and a support plate. The support plate is rotatably mounted on the bottom end of the ear plate. The transmission device is disposed in the base body and its input end is connected to the lead screw. The output end of the transmission device is connected to the support plate. When the pin is unlocked, the lead screw is adapted to drive the support plate to rotate near the bottom end of the connecting rod assembly via the transmission device. When the pin is locked, the lead screw is adapted to drive the support plate to rotate via the transmission device until it is attached to and housed at the bottom end of the ear plate.

[0015] Compared with the prior art, the beneficial effects of this application are as follows:

[0016] This invention, by incorporating a drive component and a transmission assembly, allows for locking the pin shaft by operating only the drive component when the connecting rod assembly to be tested is installed in the testing system. This eliminates the need for cumbersome operations such as installing clamps and tightening bolts as in existing technologies, greatly simplifying the installation process and significantly improving testing efficiency. Furthermore, when the limiting component releases the locking of the pin shaft, it can retract to the side of the base, thus minimizing space occupation and avoiding interference with the installation and removal of the pin shaft. This design also prevents confusion and loss of the limiting component during storage, greatly enhancing convenience. Attached Figure Description

Detailed Implementation

[0029] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0030] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.

[0031] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0032] One preferred embodiment of this application, such as Figures 1 to 11 As shown, a testing system for moving parts of a die-casting machine includes a hinge seat 4, a pin 7, a pair of limiting members 9, a driving member, and a transmission assembly 8. The hinge seat 4 is installed inside the testing system and includes a base 401 and a pair of ear plates 402 connected to the base 401. The end of the connecting rod assembly 1 to be tested engages with the two ear plates 402. The pin 7 passes through the ear plates 402 and the end of the connecting rod assembly 1. The two limiting members 9 are rotatably disposed on the outer side of the two ear plates 402. The driving member is installed inside the base 401. The transmission assembly 8 is also disposed in the base 401 and its input end engages with the driving member. The output end of the transmission assembly 8 is connected to the limiting members 9.

[0033] It is understandable that in the initial state, such as Figure 9 As shown, the limiting member 9 retracts and approaches the position of the seat 401, meaning that at this time, the limiting member 9 will not interfere with the insertion, installation, and removal / removal of the pin 7. When locking is required after the pin 7 is installed, the driving member and the transmission component 8 drive the limiting members 9 on both sides to rotate relative to each other. During the rotation, the two limiting members 9 gradually approach and abut against the pin 7, meaning that the limiting members 9 also have a centering effect on the pin 7 during the rotation, until the two limiting members 9 abut against each other and are engaged in the limiting grooves 14 at both ends of the pin 7. This achieves axial and circumferential locking of the pin 7, thereby completing the connection and installation of the end of the connecting rod assembly 1. Similarly, conversely, when disassembling the end of the connecting rod assembly 1, i.e., unlocking the pin 7, the cooperation of the driving member and the transmission component 8 causes the two limiting members 9 to rotate in opposite directions (i.e., reverse) and move away from the limiting grooves 14, so that the limiting members 9 rotate back to their initial state.

[0034] Therefore, when installing and testing the linkage assembly 1, only a single drive component needs to be operated, eliminating the need for the cumbersome installation of the clamping plate 5 and tightening of bolts as in existing technologies. This greatly simplifies the installation process and significantly improves testing efficiency. Furthermore, when the limiting component 9 releases its locking mechanism on the pin 7, it can retract next to the base 401. This avoids occupying excessive space and prevents interference with the installation and removal of the pin 7. Moreover, this design prevents confusion and loss of the limiting component 9 during storage, greatly enhancing convenience.

[0035] As a further description of the above embodiments: such as Figures 5 to 7 As shown, the driving component is a lead screw 12, which is vertically and rotatably mounted inside the base 401. The transmission assembly 8 includes a transmission block 801, a pair of transmission rods 802, a pair of transmission blocks 803, and a pair of transmission rods 804. The transmission block 801 is vertically and slidably disposed inside the base 401 and threadedly engaged with the lead screw 12. The transmission blocks 803 are horizontally and slidably disposed on both sides of the base 401. The two ends of the transmission rods 802 are rotatably connected to the transmission blocks 801 and the corresponding transmission blocks 803, respectively. The two ends of the transmission rods 804 are hinged to the corresponding transmission blocks 803 and the limiting member 9, respectively.

[0036] To facilitate a more detailed understanding of the locking and unlocking process of the aforementioned pin 7, its working principle is described below:

[0037] like Figure 4 As shown, at this time, the limiting member 9 is in the locked state of the pin 7, the limiting member 9 cooperates with the limiting groove 14, and the limiting member 9 and the seat 401 are in a perpendicular state. When unlocking the pin 7, rotate the lead screw 12 in the forward direction, as shown. Figure 6 As shown, lead screw 12 acts on transmission block 801 to move downward, transmission block 801 acts on two transmission rods 802, and transmission rods 802 act on two transmission blocks 803 to move horizontally away from each other. Figure 7 As shown, the two limiting members 9 will rotate relative to each other away from the limiting groove 14, until they rotate to a state parallel to the seat 401, and then the limiting members 9 are in a retracted state, as shown. Figure 9 As shown, the pin 7 can then be pulled out and disassembled to facilitate the installation and testing of the next set of connecting rod assembly 1. Conversely, when locking the pin 7, the lead screw 12 is rotated in the opposite direction, causing the limiting member 9 to rotate relative to and approach the limiting groove 14 of the pin 7 until it engages with the limiting groove 14 of the pin 7.

[0038] It should be noted that the pivot of the limiting member 9 is in a vertical position, and the lead screw 12 that drives it is also in a vertical position. If the lead screw 12 is to drive the two limiting members 9 to rotate simultaneously, the general design is to use gears, sprockets and chains, or belts and pulleys to drive the limiting members 9 to rotate. However, the above-mentioned methods have problems such as complex structure and large space occupation. For example, when using gears, the base 401 needs to have sufficient thickness to provide installation space for the gears; when using chain drives, multiple chains and sprockets are required, which is a complex structure; in addition, a locking structure is required to lock the lead screw 12 or the limiting member 9 after adjustment, because the above transmission methods do not have a self-locking function, that is, the limiting member 9 is in a free state after rotation, and therefore cannot play a role in locking the pin 7 axially; also, the limiting member 9 is only limited by the pivot at the end, and the stability after locking the pin 7 is not good enough.

[0039] This application adopts the design of the aforementioned transmission block 801, a pair of transmission rods 802, a pair of transmission blocks 803, and a pair of transmission rods 804, as follows: Figure 5 As shown, these components are all installed vertically along the base 401 and are evenly distributed within the base 401, making full use of the space within the base 401. Furthermore, the lead screw 12 and the transmission block 801 have a self-locking function; that is, after the lead screw 12 stops rotating, the transmission block 801 will remain in its current position under the action of the thread, thus ensuring the stable locking of the pin 7 by the limiting member 9. Additionally, as... Figure 4 As shown, when the limiting member 9 is in the locked state of the pin 7, the transmission rod 804 supports and limits the middle position of the limiting member 9, which can further enhance the stability of the limiting member 9 after locking the pin 7 and improve the overall strength.

[0040] Based on the above embodiments, the following problem may exist: Since the limiting member 9 rotates to engage with the limiting groove 14, and the limiting member 9 has a certain thickness, the ends of the limiting member 9 and the limiting groove 14 are in a clearance fit when they engage. This is because the limiting groove 14 needs to provide clearance space for the rotation of the limiting member 9. Figure 4 As shown, this may not effectively limit the pin 7 in the left and right radial directions.

[0041] Therefore, to solve the above-mentioned technical problems, an extension 16 is provided at the end of the limiting member 9, and an extension groove 17 is provided at the end of the limiting groove 14. It can be understood that when the limiting member 9 and the limiting groove 14 are engaged, the extension 16 and the extension groove 17 form an interference fit, that is, the thickness of the extension 16 is smaller than the thickness of the limiting member 9. When the extension 16 rotates, it will be forcibly engaged with the extension groove 17. This can limit the pin 7 in the left and right radial directions, and the limiting member 9 can stably limit the pin 7 in the up and down directions and the front and back directions, thereby achieving all-round limiting of the pin 7 and ensuring the stability of the connecting rod assembly 1 during test installation.

[0042] In one embodiment of this application, such as Figure 10 As shown, the cross-sectional area of ​​the middle part of the limiting member 9 is smaller than the cross-sectional area of ​​the end part of the limiting member 9. It should be understood that when the limiting member 9 rotates closer to the pin 7, the middle part of the limiting member 9 will first contact the pin 7. At this point, it is necessary to ensure that the limiting groove 14 on the pin 7 corresponds perfectly with the limiting member 9; otherwise, interference will occur when the limiting member 9 rotates. By "reducing" the size of the middle part of the limiting member 9, that is, the diameter of the limiting groove 14 is larger than that of the middle part of the limiting member 9, even if the limiting groove 14 and the limiting member 9 do not correspond perfectly during the rotation of the limiting member 9 closer to the pin 7, the thinner part of the middle part of the limiting member 9 can still smoothly enter the opening range of the limiting groove 14, improving the ease of installation. As the limiting member 9 continues to rotate closer to the limiting groove 14, the pressing action of the inclined side of the limiting member 9 can correct the pin 7, that is, the pin 7 will rotate circumferentially, causing the limiting groove 14 to correspond perfectly with the limiting member 9.

[0043] During the installation and testing of linkage assembly 1, the following problems may also be encountered: Figure 2 and Figure 4 As shown, when the end of the connecting rod assembly 1 is engaged with the ear plate 402, the operator needs to hold the end of the connecting rod assembly 1 with one hand and insert the pin 7 with the other hand. The connecting rod assembly 1 has a certain weight, and it is quite strenuous for the operator to hold it with their hand during this process, which will affect the accuracy and efficiency of the subsequent insertion of the pin 7.

[0044] To solve the above problems, such as Figure 5 , Figure 6 and Figure 8 As shown, the die-casting machine moving parts testing system also includes a transmission device 13 and a support plate 15. The support plate 15 is rotatably mounted on the bottom end of the ear plate 402. The transmission device 13 is set inside the base 401 and its input end is connected to the lead screw 12. The output end of the transmission device 13 is connected to the support plate 15.

[0045] Understandably, when the pin 7 is unlocked, the lead screw 12 can drive the support plate 15 to rotate near the bottom end of the connecting rod assembly 1 via the transmission device 13. This provides support to the end of the connecting rod assembly 1 and improves installation convenience. Conversely, when the pin 7 is locked, the lead screw 12 can drive the support plate 15 to rotate via the transmission device 13 until it is attached to and stored at the bottom end of the ear plate 402. This allows for the storage of the support plate 15 and also prevents the presence of the support plate 15 from interfering with the rotation of the connecting rod assembly 1 during testing.

[0046] As a further description of the above embodiment: the transmission device 13 includes a worm gear 1301 and a worm 1302. The worm gear 1301 is mounted on the rotating shaft of the support plate 15, and the worm 1302 is connected to the lead screw 12. That is, the support plate 15 rotates through the cooperation of the worm 1302 and the worm gear 1301. It should be understood that there is a self-locking property between the worm gear 1301 and the worm 1302. In this way, when the support plate 15 supports the end of the connecting rod assembly 1, the stability of the position of the support plate 15 can be ensured, and it will not rotate on its own due to the weight of the connecting rod assembly 1 or other factors, thereby ensuring the reliability of the support for the connecting rod assembly 1.

[0047] Furthermore, the support plates 15 are preferably a pair and correspondingly arranged on the two ear plates 402, and of course, the worm gears 1301 are also a pair and located on both sides of the worm 1302. It is understandable that when the pin 7 is not locked, such as... Figure 9 As shown, the two support plates 15 are horizontal and aligned on the same straight line, providing support at the lower end of the gap between the two ear plates 402, forming a stable support surface and providing reliable support for the end of the connecting rod assembly 1. When the pin 7 is locked, the two support plates 15 rotate 180 degrees relative to each other under the cooperation of the worm gear 1301 and the worm 1302, thus attaching and storing themselves at the bottom end of the ear plate 402. At this time, the vertical projection of the support plate 15 completely coincides with the vertical projection of the ear plate 402, thereby maximizing the space saved during storage. Compared to using a single support plate 15, the pair of support plates 15 can more evenly distribute the weight of the end of the connecting rod assembly 1, further improving the stability during support.

[0048] It should be noted that, as Figure 1 As shown, the linkage assembly 1 has three ends (i.e., left, right and lower). During the specific installation test, the hinge seat 4 at the lower end of the linkage assembly 1 can support the linkage assembly 1 itself. Therefore, the hinge seat 4 at the lower end can be installed without the support plate 15 and other structures, depending on the actual situation. Only the support plate 15 and other structures need to be installed at the hinge seats 4 at the left and right ends.

[0049] Furthermore, a matching limiting component (not shown) can be provided at one end of each of the two trays 15. It is understood that when the two trays 15 are unfolded and supported, the opposite ends of the two trays 15 can be limited by the limiting component. Since the support of the trays 15 relies entirely on the pivot of their rotating ends, excessive force during support could damage the pivot. The limiting component provides a supporting limiting force to the supporting ends of the trays 15, thereby enhancing the overall support strength of the trays 15 and extending their service life.

[0050] This application does not specifically limit the structure of the limiting component; the following two specific embodiments are provided for reference:

[0051] Structure 1: The limiting component is a magnetic component. For example, magnets are respectively set at corresponding positions on opposite ends of the two trays 15. When the trays 15 are unfolded, the two magnets attract each other, thereby limiting the supporting end of the trays 15 and enhancing the supporting strength. Structure 2: The limiting component is a snap-fit ​​component. For example, snap-fits and snap-fit ​​grooves are respectively set at corresponding positions on opposite ends of the two trays 15. When the trays 15 are unfolded, the snap-fits engage with the snap-fit ​​grooves, thereby providing a stable limiting effect on the supporting end of the trays 15. Both structures can meet practical needs, and those skilled in the art can choose according to the actual situation.

[0052] Furthermore, a drive unit flush with the base 401 can be provided at the top of the lead screw 12, and then the operator can drive the lead screw 12 to rotate by cooperating with the drive unit using a fastening tool. For example: Figure 4 As shown, the drive unit can be an internal hex head screw 10, and the fastening tool can be an internal hex wrench 11; of course, it can also be a combination of a screwdriver and a flathead / Phillips head screw.

[0053] The working principle of this invention is as follows:

[0054] ①For example Figure 2 As shown, before installation, the test moving mold 2 and the test tail plate 3 are far apart, which provides sufficient space for the installation of the connecting rod assembly 1. ② The operator can first connect the bottom end of the connecting rod assembly 1 to the hinge seat 4 on the mold closing cylinder below the test system. The connection method between the three ends of the connecting rod assembly 1 and the three hinge seats 4 in the test system is the same. The lower hinge seat 4 does not contain the support plate 15 or other structures due to its position, so it will not be described in detail here. ③ We will take the connection of the left and right ends of the connecting rod assembly 1 to the hinge seats 4 on the test moving mold 2 and the test tail plate 3 as an example for specific explanation. In the initial state, the hinge seat 4 is as follows... Figure 9As shown, the limiting component 9 is in the retracted state, and the support plate 15 is in the unfolded state. The operator can rotate and adjust the left and right ends of the connecting rod assembly 1 so that they rest on the corresponding support plate 15. At this time, the left and right ends of the connecting rod assembly 1 are roughly in a straight-line unfolded state. ④ Install the left end of the connecting rod assembly 1 first. The operator holds the left end of the connecting rod assembly 1 with one hand and holds the pin 7 with the other hand and inserts it into the ear plate 402 and the corresponding mounting hole of the connecting rod assembly 1. Insert the pin 7 into a suitable position and rotate the pin 7 so that the limiting groove 14 and the limiting component 9 are in a suitable corresponding position. Then insert the hex wrench 11 into the hex screw head 10, and then rotate the screw 12 in the opposite direction. As can be seen from the above, under the action of the transmission component 8, the limiting component 9 rotates relatively closer until it cooperates with the limiting groove 14 of the pin 7. Figure 4 As shown. Simultaneously, the lead screw 12 drives the worm gear 1302 to rotate. The worm gear 1302 acts on the two worm wheels 1301, causing the two support plates 15 to rotate relative to each other and attach to the bottom of the ear plate 402, thus completing the installation. The same procedure is repeated on the right end of the connecting rod assembly 1. Finally, the various performance indicators of the connecting rod assembly 1 are tested using a testing system.

[0055] It should be noted that the number of rotations of the limiting component 9 and the transmission assembly 8, the support plate 15 and the transmission device 13, and the lead screw 12 can be adaptively set according to actual conditions. For example, if the rotation range of the limiting component 9 is 180 degrees (i.e., half a turn), the commonly used single-stage worm gear 1302 and worm wheel 1301 transmission ratio ranges from approximately 5:1 to 100:1. Assuming the transmission ratio in this application is 30:1, this means that the worm gear 1302 rotates 30 times for the worm wheel 1301 to rotate 1 time, therefore the Allen wrench 11 needs to rotate 15 times. Assuming the moving distance of the transmission block 801 is 15 cm, and the lead of the lead screw 12 can be set to 10 mm, that is, for every one rotation of the lead screw 12, the transmission block 801 moves 10 mm, and 15 rotations is 15 cm. In other words, by reasonably setting parameters such as the lead of the lead screw 12 and the transmission ratio, the rotation angle of the limiting component 9 and the moving distance of the transmission block 801 can be precisely controlled, ensuring that the actions of each component are coordinated and consistent during installation. Furthermore, as can be seen from the above installation process, the movement of the limiter 9 and the support plate 15 can be achieved simply by rotating the lead screw 12 a set number of times, which greatly improves the installation efficiency and thus improves the testing efficiency of the connecting rod assembly 1.

[0056] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
