It adds additional components to the mold structure to protect the mold from damage by overload or impact during operation, helping to extend the service life of the mold, reduce the frequency of mold maintenance and replacement, and reduce production costs.

[0003] However, it still has the following disadvantages in actual use:

[0004] In actual use, the existing mold is prone to excessive stamping force, which may cause damage to the mold. Therefore, an overload protection block is used to protect the mold. However, during long-term use, if the damage to the overload protection block is not discovered in time, the performance of the overload protection block will be greatly reduced. Utility Model Content

[0005] The purpose of the present utility model is to provide a mold with an overload protection block to solve the problem raised in the above background technology that the existing mold is prone to excessive stamping force during actual use, which may cause damage to the mold. Therefore, an overload protection block is used to protect the mold. However, during long-term use, if the damage to the overload protection block cannot be discovered in time, the performance of the overload protection block will be greatly reduced.

[0006] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0007] The utility model is a mold with an overload protection block, comprising:

[0008] Main body, including overload protection block;

[0009] The mounting assembly includes a mounting frame fixed to one end of the lower surface of the overload protection block, slide grooves provided inside both sides of the mounting frame, sliders slidably connected to the inside of the slide grooves, a connecting plate connected to the inner surface of the slider, a silicone pad fixed to the upper surface of the connecting plate, and a magnetic overload protection sensor movably connected to the top surface of the silicone pad;

[0010] The limiting component includes a fixing column fixed to the other end of the lower surface of the overload protection block.

[0011] Furthermore, limiting holes are provided at the bottom ends of both sides of the installation frame, and there are eight groups of limiting holes in total, with four groups of limiting holes being provided on each side.

[0012] Furthermore, the limiting holes, the connecting plate and the interior of the slider are connected through the limiting columns, and threaded rods are fixed on both side surfaces of the limiting columns.

[0013] Furthermore, the outer surface of the threaded rod is threadedly connected to a connecting pipe, and guide columns are fixed to the surfaces of both sides of the connecting pipe. There are two groups of connecting pipes in total, and two groups of guide columns are fixed to the surface of any group of connecting pipes.

[0014] Furthermore, a first support plate is fixed to one side of the lower surface of the fixed column, a second support plate is fixed to the other side of the lower surface of the fixed column, and a movable plate is hinged to the bottom end of the first support plate.

[0015] Furthermore, a connecting wire is fixed inside one side of the movable plate, a spring is fixed inside one side of the second support plate, and a pressing plate is fixed on the other side of the spring;

[0017] Furthermore, the main body also includes a lower die base fixed to the lower surface of the overload protection block and an upper die base movably connected to the top of the lower die base.

[0018] Compared with the prior art, the advantages of the present invention are:

[0019] 1. The utility model sets a magnetic overload protection sensor. When the mold is overloaded, the magnetic material will produce a magnetic field change. The sensor detects the change and triggers the protection mechanism, issuing an alarm signal. The alarm signal is issued in time, thereby reducing the loss of the overload protection block and extending the service life of the overload protection block. In addition, with the setting of the mounting frame and the connecting plate, the sensor can be not only quickly fixed inside the mold, but also more stably fixed inside the mold.

[0020] 2. Based on beneficial effect 1, with the use of the limiting component, after the magnetic overload protection sensor is installed, by placing the power cord of the magnetic overload protection sensor into the gap between the first support plate and the second support plate, and fitting the movable plate to the bottom surface of the second support plate, the power cord can be limited to the bottom of the overload protection block to avoid excessive bending at the power cord connector, resulting in poor contact and affecting the normal use of the magnetic overload protection sensor.

[0036] Example 1

[0037] See also Figure 1-Figure 5 As shown, this embodiment is a mold with an overload protection block, comprising:

[0038] The main body includes an overload protection block 13;

[0039] The mounting assembly includes a mounting frame 21 fixed to one end of the lower surface of the overload protection block 13, slide grooves 22 defined within both sides of the mounting frame 21, sliders 23 slidably connected to the insides of the slide grooves 22, a connecting plate 24 connected to the inner surface of the slider 23, a silicone pad 28 fixed to the upper surface of the connecting plate 24, and a magnetic overload protection sensor 29 movably connected to the top surface of the silicone pad 28;

[0040] The limiting assembly includes a fixing column 31 fixed to the other end of the lower surface of the overload protection block 13;

[0041] The bottom ends of both sides of the mounting frame 21 are provided with limiting holes 25. There are eight groups of limiting holes 25 in total, with four groups of limiting holes 25 on each side.

[0042] The limit holes 25 are provided in multiple groups, and the corresponding limit holes 25 can be selected according to the actual width of the magnetic overload protection sensor 29;

[0043] The limiting hole 25, the connecting plate 24 and the slider 23 are connected through the limiting column 26, and the two sides of the limiting column 26 are fixed with threaded rods 27;

[0044] The limiting posts 26 are provided to limit the connection plate 24 inside the mounting frame 21, and the threaded rods 27 are provided to stably fix the connection plate 24 inside the mounting frame 21;

[0045] The outer surface of the threaded rod 27 is threadedly connected to a connecting tube 271. Guide posts 272 are fixed to the surfaces of both sides of the connecting tube 271. There are two groups of connecting tubes 271 in total. Two groups of guide posts 272 are fixed to the surface of any one group of connecting tubes 271.

[0046] The connecting tube 271 is provided for installation on both sides of the threaded rod 27 to limit the position of the connecting plate 24. The guide column 272 is provided to facilitate the rotation of the connecting tube 271.

[0047] The main body also includes a lower die base 12 fixed to the lower surface of the overload protection block 13 and an upper die base 11 movably connected to the top of the lower die base 12;

[0048] The upper die base 11 and the lower die base 12 are used in conjunction with each other to press the product.

[0049] Working principle;

[0050] When installing the magnetic overload protection sensor 29;

[0051] First, after fixing the mounting frame 21 on the bottom surface of the overload protection block 13, the magnetic overload protection sensor 29 is placed inside the mounting frame 21, and an upward force is applied to the connecting plate 24 to make the slider 23 slide inside the slide groove 22. When the silicone pad 28 is in contact with the magnetic overload protection sensor 29, the limiting post 26 is placed into the corresponding limiting hole 25. After the limiting post 26 passes through the connecting plate 24, the slider 23 and the interior of the mounting frame 21, the connecting tube 271 is passed through the threaded rod 27. With the assistance of the connecting tube 271, the connecting tube 271 is rotated so that the connecting tube 271 is in contact with the surface of the mounting frame 21. The installation of the magnetic overload protection sensor 29 is completed. When the magnetic overload protection sensor 29 is installed, when the mold is overloaded, the magnetic material will produce a magnetic field change. The sensor detects the change and triggers the protection mechanism, sending an alarm signal.

[0052] This step reduces the loss of the overload protection block 13 and prolongs the service life of the overload protection block 13 .

[0053] Example 2

[0054] See also Figures 1-4 、 Figure 6 As shown, this embodiment is based on the above embodiment 1 and also includes:

[0055] A first support plate 32 is fixed to one side of the lower surface of the fixed column 31, a second support plate 33 is fixed to the other side of the lower surface of the fixed column 31, and a movable plate 34 is hinged to the bottom end of the first support plate 32;

[0056] The fixed column 31 is used to receive and install the first support plate 32 and the second support plate 33, and the movable plate 34 is used to limit the power line of the magnetic overload protection sensor 29;

[0057] A connecting wire 35 is fixed inside one side of the movable plate 34, a spring 36 is fixed inside one side of the second support plate 33, and a pressing plate 37 is fixed on the other side of the spring 36;

[0058] The top end of the connecting wire 35 is located in the gap between the pressing plate 37 and the second supporting plate 33;

[0059] Under the elastic force of the spring 36, the distance between the pressing plate 37 and the second support plate 33 is changed, thereby completing the disassembly and assembly of the connecting wire 35. The connecting wire 35 is used to stably fix the movable plate 34 to the bottom of the second support plate 33;

[0060] Working principle;

[0061] When fixing the power line of the magnetic overload protection sensor 29;

[0062] First, place the power cord of the magnetic overload protection sensor 29 into the gap between the first support plate 32 and the second support plate 33, then apply an upward force to the movable plate 34 so that the upper surface of the movable plate 34 is in contact with the lower surface of the second support plate 33. Then, apply an outward pulling force to the pressing plate 37, pass the connecting wire 35 through the gap between the pressing plate 37 and the second support plate 33, and continue to apply an upward force to the connecting wire 35 so that the movable plate 34 is in contact with the second support plate 33. Then, remove the force applied to the pressing plate 37, and under the elastic force of the spring 36, the pressing plate 37 and the connecting wire 35 are in contact.

[0063] This step prevents the power line connector from being excessively bent, which would cause poor contact and affect the normal use of the magnetic overload protection sensor 29.
