[0033] In order for those skilled in the art to better understand the solutions of the present application, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0034] Figure 1 A structural view of a mold frame device for pressing a license plate of a motor vehicle provided for an embodiment of the present application is shown in the figure, Figure 1 As shown in the figure, the device for pressing a license plate of a motor vehicle comprises: a first mold frame 1 for mounting a first character mold 5; a second mold frame 2 arranged below the first mold frame 1 and used for mounting a second character mold 7, the second character mold 7 and the first character mold 5 being located between the first mold frame 1 and the second mold frame 2; and a driving mechanism 3, the driving mechanism 3 being movably connected with the first mold frame 1 and the second mold frame 2 respectively, the first mold frame 1 and the second mold frame 2 being capable of being moved towards each other under the action of an external force to press a license plate blank, and the driving mechanism 3 being used for driving the first mold frame 1 and the second mold frame 2 to move relatively so as to make the position of the first mold frame 1 coincide with or be staggered with the position of the second mold frame 2.

[0035] For the convenience of understanding, first introduce the process of using the mold frame device to press the license plate, usually the first character mold 5, the corresponding concave mold is installed in the first mold frame 1, the second character mold 7, the corresponding convex mold is installed in the second mold frame 2, the first mold frame 1 is located above the second mold frame 2, therefore, the first mold frame 1 can also be called the upper mold frame, and the second mold frame 2 is called the lower mold frame, after the first character mold 5 and the second character mold 7 are installed, the license plate blank is placed between the first character mold 5 and the second character mold 7, and the license plate blank is pressed by using the pressing machine to press the first mold frame 1 and the second mold frame 2, usually the pressing mode of the pressing machine is that the first mold frame 1 is located below the fixed baffle, the pressing machine presses the second mold frame 2 to the first mold frame 1, the first mold frame 1 and the second mold frame 2 are pressed to the fixed baffle, and the first mold frame 1 and the second mold frame 2 are pressed, so as to press the license plate blank.

[0036] The first mold frame 1, the second mold frame 2 and the driving mechanism 3 are movably connected in the embodiment of the application, the first mold frame 1 is located above the second mold frame 2, and there is a certain distance between the two. Under the action of external force, for example, under the driving of the pressing machine, the first mold frame 1 and the second mold frame 2 can approach each other and press each other, so as to press the license plate blank located therebetween; the driving mechanism 3 is used to drive the relative movement of the first mold frame 1 and the second mold frame 2, which can drive the movement of the first mold frame 1 relative to the second mold frame 2, or drive the movement of the second mold frame 2 relative to the first mold frame 1, or simultaneously drive the movement of the first mold frame 1 and the second mold frame 2, so that the positions of the first mold frame 1 and the second mold frame 2 coincide or are staggered, that is, the second mold frame 2 is located directly below or obliquely below the first mold frame 1. When the second mold frame 2 is staggered with the first mold frame 1, it is convenient to place the license plate blank at the corresponding position of the second mold frame 2 or the first mold frame 1. The embodiment of the application does not make specific limitation on the driving mechanism 3. The driving mechanism 3 can drive the first mold frame 1 and / or the second mold frame 2 to move in a straight line direction, or can drive the first mold frame 1 and / or the second mold frame 2 to rotate in a horizontal direction. No matter how the first mold frame 1 and the second mold frame 2 are driven to move, the purpose is to realize the coincidence or staggering of the positions of the first mold frame 1 and the second mold frame 2. Figure 1 Only the structure diagram of the mold frame device provided by the application does not constitute a limitation on the mold frame device of the application.

[0037] The mold frame device for motor vehicle license plate pressing provided by the embodiment of the application comprises: a first mold frame for mounting a first character mold; a second mold frame arranged below the first mold frame for mounting a second character mold, the second character mold and the first character mold being located between the first mold frame and the second mold frame; and a driving mechanism, which is movably connected with the first mold frame and the second mold frame respectively, and is used for driving the first mold frame and the second mold frame to move relative to each other so that the position of the first mold frame coincides with or is staggered with the position of the second mold frame. The driving mechanism is used for driving the first mold frame and the second mold frame to move relative to each other so that the position of the first mold frame coincides with or is staggered with the position of the second mold frame, thereby effectively avoiding the manual opening of the upper mold frame by a certain angle for placing the license plate blank, reducing the labor intensity of the staff, and when the position of the first mold frame is completely staggered with the position of the second mold frame, the license plate blank will not block the line of sight of the staff when placed, effectively avoiding the inaccurate placement of the license plate blank, thereby improving the convenience and accuracy of license plate processing.

[0038] Based on the above embodiment, as shown in Figure 1 The driving mechanism 3 comprises two linear modules, and the two linear modules are fixed in parallel on two sides of the rack 4. Figure 2 The structure diagram of the linear module provided by the embodiment of the application is shown in Figure 2 The linear module comprises a guide rail support plate 301, two ball screw modules 302, two driving motors 303 and two mold frame seats 304. The two ball screw modules 302 are fixed in parallel on the guide rail support plate 301. One end of the ball screw module 302 is connected with the driving motor 303, and the other end of the ball screw module 302 is provided with the mold frame seat 304. The driving motor 303 is used for driving the ball screw module 302 to move and drive the mold frame seat 304 to reciprocate along the length direction of the guide rail support plate 301. Figure 1 The two ends of the first mold frame 1 are movably connected with the two mold frame seats 304 farthest away from each other on the two linear modules, respectively. The two ends of the second mold frame 2 are movably connected with the two mold frame seats 304 closest to each other on the two linear modules, respectively, and the second mold frame 2 is located below the first mold frame 1.

[0039] In this embodiment, the frame 4 serves as a support and fixation unit. The bottom surface of the guide rail support plate 301 of the linear module is fixedly connected to the frame 4. Two ball screw modules 302 are fixed parallel to each other on the top surface of the guide rail support plate 301. Two drive motors 303 can be connected to the same end of the two ball screw modules 302 respectively. A mold frame seat 304 is installed at the end opposite to the drive motor 303. The mold frame seat 304 is used to movably connect with the first mold frame 1 and the second mold frame 2 to ensure that the first mold frame 1 and the second mold frame 2 can move closer or further apart under the action of external force. The specific method of movable connection can be sleeve connection or movable connection through telescopic mechanism. This embodiment does not specifically limit this. The drive motor 303 drives the ball screw module 302 to move, which in turn drives the mold frame 304 to move, so that the first mold frame 1 and / or the second mold frame 2 move linearly along the length direction of the guide rail support plate 301. The first mold frame 1 and the second mold frame 2 are staggered. After the license plate blank is put in, the first mold frame 1 and the second mold frame 2 overlap each other, and then the license plate blank can be stamped by the press.

[0040] Based on the above embodiments, this application provides a connection method between a mold holder and a mold frame (a first mold frame and a second mold frame). Figure 3 A partial structural diagram of a mold holder and mold frame provided in this application embodiment is shown below. Figure 3 As shown, the mold holder 304 is provided with a mold holder guide 305. Both ends of the first mold holder 1 and the second mold holder 2 are provided with guide mounting holes. The first mold holder 1 and the second mold holder 2 are sleeved with the mold holder guide 305 through the guide mounting holes. The first mold holder 1 and the second mold holder 2 can reciprocate along the length direction of the mold holder guide 305.

[0041] In this embodiment of the application, the number of mold holder guides 305 provided on each mold holder 304 is not limited, such as Figure 2 As shown, each mold holder 304 is provided with two mold holder guides 305, and correspondingly, each end of the mold frame (first mold frame 1 and second mold frame 2) is provided with two guide mounting holes. Based on this, the mold holder guide 305 is a conical guide, with the larger diameter end of the conical guide connected to the mold holder 304. Therefore, when the first mold frame 1 and the second mold frame 2 are pressed against the fixed baffle by the press, the first mold frame 1 and the second mold frame 2 slide along the conical guide from the larger diameter end to the smaller diameter end. The resistance during the sliding process is small, and they will not get stuck on the mold holder guide 305, ensuring the stability and positioning accuracy of the first mold frame 1 and the second mold frame 2 during the stamping action, and making it easier to stamp the license plate.

[0042] Based on the above embodiments, such as Figure 3As shown, this embodiment of the application also includes a copper sleeve 306, which is sleeved on the conical guide and located between the guide mounting hole and the conical guide. By providing the copper sleeve 306, wear between the mold holder guide 305 and the mold mounting hole can be reduced.

[0043] Furthermore, to prevent the copper sleeve 306 from dislodging from the guide mounting hole when the mold base moves up and down along the mold holder guide 305, a spring 307 is also provided. A first limiting step is provided at the end of the guide mounting hole near the mold holder 304, and a second limiting step is provided at the end of the copper sleeve 306 away from the mold holder 304. The first limiting step and the second limiting step abut against each other. A third limiting step is provided at the end of the mold holder guide 305 with a smaller diameter. The spring 307 is sleeved on the mold holder guide 305 and located between the third and second limiting steps. When the first mold base 1 and the second mold base 2 move up and down with the stamping action, the spring 307 can provide a certain downward pressure on the mold base and also ensure that the copper sleeve 306 does not dislodge.

[0044] Based on the above embodiments, Figure 4 This is a partial structural diagram of a first mold frame and a drive mechanism provided in an embodiment of this application. Figure 5 A partial structural diagram of a second mold frame and a drive mechanism provided in an embodiment of this application is shown below. Figure 4 and Figure 5 As shown, in this embodiment of the application, the first mold frame 1 is provided with a first character mold slot, and the first character mold 5 is provided with limiting buckles on both sides. The limiting buckles cooperate with the first character mold slot to install the first character mold 5 on the first mold frame 1. The second mold frame 2 is provided with a second character mold slot, and a first positioning pin 8 is provided in the second character mold slot. The bottom of the second character mold 7 is provided with a first positioning hole 701. The first positioning hole 701 engages with the first positioning pin 8 to install the second character mold 7 on the second mold frame 2; wherein, the second character mold 7 is a frustum shape.

[0045] The embodiments of this application do not specifically limit the shape of the first positioning pin 8 and the first positioning hole 701. Figure 6 A cross-sectional view of a second character model provided in an embodiment of this application, such as... Figure 6 As shown, the bottom of the second character mold 7 is provided with two first positioning holes 701. If the first positioning pin 8 is a trapezoidal positioning pin, the first positioning hole 701 is a trapezoidal positioning hole that matches the trapezoidal positioning pin. The first positioning hole 701 and the first positioning pin 8 cooperate, and the second character mold 7 can be positioned in one go without needing to be adjusted again. Figure 7 A side view of a second typeface provided for implementation of this application. Figure 8 A top view of a second typeface provided for implementation of this application, such as Figure 8 As shown, the upper surface of the second character mold 7 has raised numbers, such as... Figure 7As shown, the second character mold 7 is in the shape of a truncated pyramid, that is, the area of ​​the upper surface of the second character mold 7 is greater than the area of ​​the lower surface. The truncated pyramid shape of the second character mold 7 makes it easy to put the second character mold 7 into the second character mold slot.

[0046] In this embodiment, by setting a limiting buckle and a first character mold slot, the first character mold 5 can be accurately placed into the corresponding position of the first mold frame 1. By setting a second character mold slot, a first positioning pin 8 and a first positioning hole 701, the accuracy of the placement position of the second character mold 7 can be ensured without secondary positioning after the second character mold 7 is placed, and the character mold can be ensured not to shift during the stamping process of the license plate blank.

[0047] Based on the above embodiments, such as Figure 4 and Figure 5 As shown, both the first mold frame 1 and the second mold frame 2 are equipped with elastic pins 6. The elastic pins 6 are located around the first and second character mold slots. In this embodiment, the number of elastic pins 6 is not specifically limited and can be set according to actual needs. The elastic pins 6 can effectively prevent the license plate blank from getting stuck in the first mold frame 1 or the second mold frame 2 during the stamping process.

[0048] Based on the above embodiments, such as Figure 5 As shown, in this embodiment of the application, the surface of the second mold frame 2 facing the first mold frame 1 is provided with a plurality of second positioning pins 9. The plurality of second positioning pins 9 are arranged around the second character mold slot. The second positioning pins 9 are used to abut against the periphery of the license plate blank. The first mold frame 1 is provided with a second positioning hole. When the first mold frame 1 and the second mold frame 2 are close together, the second positioning pins 9 can pass through the second positioning hole.

[0049] The embodiments of this application do not specifically limit the second positioning pin 9. The second positioning pin 9 can be designed as a tapered positioning pin. The second positioning pin 9 and the second positioning hole facilitate more accurate engagement of the first mold frame 1 and the second mold frame 2 when the press performs the stamping action from below. At the same time, it can limit the position of the license plate blank around the perimeter, which not only facilitates the positioning of the license plate blank when it is placed, but also ensures that the license plate does not shift during the stamping process.

[0050] For ease of understanding, the following describes the usage of the mold frame device for pressing motor vehicle license plates. Drive the drive motor 303 corresponding to the first mold frame 1 and / or the second mold frame 2 so that the first mold frame 1 and the second mold frame 2 are completely offset. Then, place the first letter mold 5 and the second letter mold 7 into the corresponding positions of the first mold frame 1 and the second mold frame 2 respectively. Place the license plate blank on the upper surface of the second mold frame 2. Use the second positioning pin 9 on the second mold frame 2 to limit the license plate blank around its perimeter. Then, drive the drive motor 303 to drive the first mold frame 1 and the second mold frame 2 to overlap. Finally, cooperate with the press to press the license plate blank.

[0051] The mold frame device for pressing motor vehicle license plates described in this application can not only be used in conjunction with stamping equipment to achieve semi-automatic production of license plate pressing, but also in conjunction with a robotic arm to achieve fully automated production of motor vehicle license plates without human intervention. The first mold frame and the second mold frame adopt dual drive and have their own action modules. After the letter mold is placed, the first mold frame can be moved away independently. The operator does not need to manually flip over the heavy mold frame after the letter mold is placed, which makes it easier to put the license plate blank in. Without the first mold frame obstructing the view, the probability of the license plate blank being placed in the wrong direction or position is greatly reduced. Both the first mold frame and the second mold frame are equipped with elastic pin structures to push out the license plate blank. The license plate blank can be automatically pushed out after stamping without human intervention. The first mold frame is equipped with a first letter mold slot, and the second mold frame is equipped with a second letter mold slot and a first positioning pin. After the letter mold is placed, the accuracy of the letter mold placement can be ensured without secondary positioning, and the letter mold can be prevented from shifting during the stamping process of the license plate blank.
