[0042] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0043] The core of the utility model is to provide a mold replacement device, which is convenient for pulling the mold out of the machine, saving manpower and reducing the labor intensity.

[0044] Please refer to Figure 1 and Figure 2 The embodiment of the utility model provides a mold replacement device, including a support frame 1, a screw rod 2, a hook 3, a universal joint 4 and a torque wrench 5. The support frame 1 includes a support column 11 for abutting against the outer side of a machine where the mold is set; the screw rod 2 has a preset length, and the screw rod 2 is threadedly connected to the support frame 1; the hook 3 is used to hook the handle of the mold, and the hook 3 is connected to one end of the screw rod 2 through a universal joint 4; the torque wrench 5 is used to be connected to the other end of the screw rod 2 to drive the screw rod 2 to rotate under the action of an external force, so that the screw rod 2 moves relative to the support frame 1 along the length direction of the screw rod 2, so that the hook 3 drives the mold out of the machine.

[0045] When the mold needs to be pulled out of the machine, the support frame 1 is placed on the side of the machine, the support column 11 is abutted against the outside of the machine, the hook 3 is hooked on the handle of the mold, and then the torque wrench 5 is connected to the end of the screw rod 2 away from the hook 3, and the torque wrench 5 is turned to drive the screw rod 2 to rotate. Since the screw rod 2 is threadedly connected to the support frame 1, the screw rod 2 rotates while moving relative to the support frame 1 along the axial direction of the screw rod 2, and then the screw rod 2 drives the hook 3 to move, so that the hook 3 pulls the mold out of the machine. When turning the torque wrench 5, the torque wrench 5 drives the screw rod 2 to rotate using the lever principle. Therefore, the mold can be smoothly pulled out of the machine using very little force, which saves manpower, reduces the intensity of manual labor, and does not cause damage to the machine and the mold.

[0046] It is understandable that one end of the screw rod 2 for connecting with the torque wrench 5 is provided with an external hexagonal plug connector. When in use, the internal hexagonal hole of the torque wrench 5 is inserted into the external hexagonal plug connector of the screw rod 2, and then an external force is applied to the torque wrench 5, and the torque is transmitted through the joint surface of the external hexagonal plug connector and the internal hexagonal hole, so that the torque wrench 5 drives the screw rod 2 to rotate. When not in use, the torque wrench 5 is removed from the screw rod 2.

[0047] In addition, the screw rod 2 and the hook 3 are connected via a universal joint 4, that is, the screw rod 2 can rotate relative to the hook 3 via the universal joint 4, that is, in the process of the screw rod 2 rotating and moving, only the hook 3 has a moving movement, thereby preventing the hook 3 from generating torque on the mold and affecting the pulling out of the mold.

[0048] It should be noted that the present embodiment does not limit the specific structure of the universal joint 4, as long as it can meet the connection requirements of the screw rod 2 and the hook 3, and those skilled in the art can participate in the relevant technology. In addition, the present embodiment does not limit the specific connection method of the hook 3 and the screw rod 2 to the universal joint 4, as long as the universal joint 4 can be connected to the hook 3 and the screw rod 2 respectively.

[0049] In some embodiments, the hook 3 and the screw rod 2 are respectively connected with the universal joint 4 by threads, so that the hook 3 and the screw rod 2 can be disassembled from the universal joint 4 respectively; the threaded engagement direction of the hook 3 and the screw rod 2 with the universal joint 4 is opposite to the threaded engagement direction of the screw rod 2 and the support frame 1. That is to say, in this embodiment, the universal joint 4 and the hook 3 and the universal joint 4 and the screw rod 2 can be disassembled by threaded connection. Therefore, when not in use, the hook 3, the universal joint 4 and the screw rod 2 can be disassembled and separated. In this case, it is also convenient to unscrew the screw rod 2 from the support frame 1 and assemble it together when in use. It should be noted that in some embodiments, the number of screw rods 2 can be set to multiple, and the multiple screw rods 2 have different lengths. Therefore, screw rods 2 of different lengths can be replaced by disassembly. For example, the number of screw rods 2 is two, one of which is 300 mm long and the other is 500 mm long. Different screw rods 2 can be replaced according to actual needs.

[0050] It can be understood that the threaded engagement directions of the hook 3 and the screw rod 2 with the universal joint 4 are opposite to the threaded engagement directions of the screw rod 2 and the support frame 1. In this way, when the torque wrench 5 drives the screw rod 2 to rotate, the threaded connection between the screw rod 2 and the universal joint 4 can be prevented from loosening. On the contrary, as the screw rod 2 rotates, the connection between the screw rod 2 and the universal joint 4 becomes tighter and tighter, thereby ensuring the reliability of the connection.

[0051] In addition, a threaded hole can be directly opened on the support frame 1 to connect the screw rod 2 to the support frame 1, or the support frame 1 can be connected to the screw sleeve 13 to connect the screw rod 2 to the screw sleeve 13. By providing the screw sleeve 13, it is convenient to process the internal thread on the one hand, and it is convenient to adjust the length of the screw sleeve 13 and the screw rod 2 on the other hand, so as to ensure the stability of the movement of the screw rod 2.

[0052] In addition, considering that the weight of the mold is heavy or has a certain temperature (for example, the mold weighing 80KG is involved in production, and the mold temperature can reach 180°C), it is not convenient to rely on manpower to support and carry the mold after it is pulled out. In order to solve this technical problem, in some embodiments, the support frame 1 is provided with a bearing platform and a lifting drive mechanism connected to the bearing platform, and the bearing platform is used to receive the mold pulled out of the machine; the lifting drive mechanism is used to drive the bearing platform to rise and fall, so that the bearing platform rises to a position equal to the bottom surface of the mold before the mold is pulled out. That is to say, this embodiment lifts the bearing platform through the lifting drive mechanism, so that the bearing platform has a suitable height. In this way, before the mold is pulled out, by raising the bearing platform to a position equal to the bottom surface of the mold, the bearing platform receives the mold pulled out by the hook 3, which can avoid manual acceptance of the mold pulled out of the machine, save manpower, and effectively prevent safety accidents.

[0053] It should be noted that the present embodiment does not limit the specific structure of the lifting drive mechanism, as long as it can drive the carrying platform to rise and fall.

[0054] Furthermore, in order to ensure that the carrying platform is in the correct position, in some embodiments, the support frame 1 is provided with a first detection device and a control device, the control device is respectively connected to the first detection device and the lifting drive mechanism, the first detection device is used to detect whether the carrying platform rises to a position at the same height as the bottom surface of the mold; the control device is used to receive the detection signal of the first detection device, and when it is determined that the carrying platform has risen into place according to the detection signal of the first detection device, the lifting drive mechanism is controlled to stop the action, so that the carrying platform stays in the correct position, avoiding the carrying platform being higher or lower than the bottom surface height of the mold, thereby facilitating the mold to fall smoothly on the carrying platform after being pulled out.

[0055] It should be noted that this embodiment does not limit the specific structure of the first detection device and its detection method, as long as it can detect the position of the carrying platform to determine whether the carrying platform rises to a position equal to the bottom surface of the mold.

[0056] In addition, in some embodiments, the support frame 1 is provided with a second detection device, an alarm device and a control device, and the control device is connected to the second detection device and the alarm device respectively. The second detection device is used to detect whether the mold is fully pulled out; the alarm device is used to sound an alarm; the control device is used to receive the signal sent by the second detection device, and when the second detection device detects that the mold is fully pulled out, the alarm device is controlled to sound an alarm. That is to say, this embodiment uses the second detection device to detect the position of the mold to ensure whether it is fully pulled out. When the mold is fully pulled out, the control device controls the alarm device to sound an alarm, so that the operator can stop applying external force to the torque wrench 5 in time according to the alarm.

[0057] It should be noted that the present embodiment does not limit the specific structure and detection method of the second detection device, as long as it can detect the position of the mold to determine whether the mold is completely pulled out. In addition, the specific structure of the alarm device is not limited, and the alarm device can be a buzzer or an indicator light.

[0058] In addition, in order to limit the position of the mold on the carrying platform, in some embodiments, two parallel limit guide rails are provided on the carrying platform, and the two limit guide rails are used to limit and guide the two sides of the mold pulled onto the carrying platform. The two limit guide rails are each used to have a guide portion facing one end of the mold, and the guide portions of the two limit guide rails form a bell mouth. In other words, when the mold is pulled out, the part of the mold that is pulled out first enters the bell mouth of the two limit guide rails, and gradually enters between the two limit guide rails from the bell mouth, and then under the action of the two limit guide rails, the mold moves along the direction defined by the limit guide rails, and finally the mold stays on the carrying platform at a position between the two limit guide rails. This is conducive to improving the stability of the mold when it is pulled out, and is conducive to pulling the mold out from the base in the machine.

[0059] In addition, it should be noted that the support frame 1 can be a structure having a base and a frame body, the base plays a supporting role, and the frame body is used to set the support column 11, the screw rod 2 and / or the bearing platform, etc. In order to facilitate the transfer of the support frame 1, in some embodiments, the support frame 1 includes a base arranged on the ground, and the bottom of the base is provided with a plurality of casters with foot brakes for moving the support frame 1. In this way, it is convenient to set the support frame 1 on the side of the machine, and it is also convenient to transfer the pulled mold to the desired position. In addition, the support frame 1 can also be set in an existing structure, and the existing structure is used to support the support frame 1.

[0060] For example, in some embodiments, the mold replacement device also includes a hydraulic cart 6, and the support frame 1 is arranged on the hydraulic cart 6; the hydraulic lifting platform 61 of the hydraulic cart 6 is used to receive the mold pulled out of the machine. That is to say, this embodiment improves the existing hydraulic cart 6, and uses the hydraulic cart 6 to support the support frame 1, so that the support column 11 and the screw rod 2 are located at a suitable position. In addition, the hydraulic lifting platform 61 of the hydraulic cart 6 is used to receive the mold pulled out of the machine, and there is no need to separately set a load-bearing platform and a lifting drive mechanism on the support frame 1. The hydraulic cart 6 is very common in industrial production. By improving the hydraulic cart 6, the improved hydraulic cart 6 is used to pull out the mold. When not in use, the hydraulic cart 6 can also be used in other places by removing the support frame 1 from the hydraulic cart 6. The structure is simple and easy to implement.

[0061] When the support frame 1 is arranged on the hydraulic vehicle 6, in some embodiments, the support frame 1 includes a support column 11, a connecting column 12 and a fixing column 14, the number of the support columns 11 is two, the two support columns 11 are arranged in parallel, the connecting column 12 is connected between the two support columns 11, the connecting column 12 is connected with a screw sleeve 13 with an internal thread, and the screw rod 2 is threadedly connected to the screw sleeve 13; the two fixing columns 14 are vertically connected to the two support columns 11 in a one-to-one correspondence, and the fixing columns 14 are fitted and connected to the frame 62 of the hydraulic vehicle 6. The structure is simple and easy to implement.

[0062] Furthermore, in order to improve the reliability of the connection between the fixed column 14 and the frame 62 of the hydraulic vehicle 6, in some embodiments, a first adapter plate 7 is provided between the fixed column 14 and the frame 62 of the hydraulic vehicle 6, and the fixed column 14, the first adapter plate 7 and the frame 62 are fixedly connected; a second adapter plate 8 is provided on the side of the frame 62 away from the first adapter plate 7, and the second adapter plate 8 is connected to the first adapter plate 7, so that the frame 62 is sandwiched between the first adapter plate 7 and the second adapter plate 8. In other words, this embodiment improves the reliability of the connection between the fixed column 14 and the frame 62 of the hydraulic vehicle 6 by adding the first adapter plate 7 and the second adapter plate 8.

[0063] Furthermore, in some embodiments, the position of the fixing column 14 along the height direction relative to the first adapter plate 7 is adjustable. That is, in this embodiment, by adjusting the position of the fixing column 14 along the height direction relative to the first adapter plate 7, the height position of the support frame 1 on the frame 62 of the hydraulic vehicle 6 is adjustable as a whole, so that the hook 3 and the support column 11 have the correct height position, which is convenient for pulling out the mold.

[0064] It should be noted that the present embodiment does not limit the specific implementation method of making the position of the fixing column 14 adjustable relative to the first adapter plate 7 along the height direction, as long as the height position of the fixing column 14 is adjustable.

[0065] It should also be noted that, in this specification, relational terms such as first and second, etc. are merely used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0067] The above is a detailed introduction to the mold replacement device provided by the utility model. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiments is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the utility model.
