[0002] Copper plate is the basic material of the electronics industry. It is used to process and manufacture printed circuit boards and is widely used in electronic products such as new energy charging piles and computers. In new energy charging piles, copper clad laminates are usually used to connect various electronic components. During the cold pressing process of copper clad laminates, pressure is applied to cause the copper clad laminates to undergo plastic deformation under the action of the mold to obtain the desired shape and size.

[0003] During the cold pressing process, the copper clad laminate will be subjected to extrusion pressure. If the pressure distribution is uneven, it may cause the copper clad laminate to slip sideways during the cold pressing process. The existing cold pressing device is not convenient for maintaining continuous limitation on the side of the copper clad laminate during the cold pressing process, resulting in insufficient stability of the copper clad laminate during the cold pressing process. Summary of the invention

[0014] Cold pressing treatment: The copper clad laminate is cold pressed by the upper die assembly. During the cold pressing process, the copper clad laminate drives the movable pressure platform and the copper clad laminate into the forming cavity under the pressure of the upper die assembly.

The positioning plate enters the makeshift cavity as the die assembly is pressed, and the positioning plate always maintains a limit on the side wall of the copper clad laminate, which helps prevent the copper clad laminate from sliding sideways during the cold pressing process.

At the same time, the linkage assembly is used to move the linkage positioning plate so that the positioning plate maintains a certain distance from the copper clad laminate, and the copper clad laminate is taken out.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] According to the present invention, during the cold pressing process, the copper clad laminate drives the movable pressure platform and the copper clad laminate into the forming cavity under the pressure of the upper die assembly, the positioning plate moves synchronously with the clearance seat, and then when the die assembly continues to press, the positioning plate enters the clearance cavity under the pressure, thereby achieving the goal of always keeping the side of the copper clad laminate limited during the cold pressing process.

DETAILED DESCRIPTION

[0038] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0040] It should be understood that, specifically, the first elastic support member 9 can be a gas spring, and the height adjustment assembly is specifically four first cylinders 4, which are fixedly mounted on the top surface of the cold press table 1, and the piston rod passes through the cold press table 1 and is fixedly connected to the bottom surface of the lower support mold 3;

[0041] The entire cold pressing process is as follows:

[0042] Installing the copper clad laminate: The lower support mold 3 is adjusted to move out of the receiving frame 2 by the height adjustment component, and the linkage positioning plate 8 is moved away from the copper clad laminate by the linkage of the linkage component to make room for the placement, and the copper clad laminate is placed on the movable pressure platform 10;

[0043] Adjustment and positioning: In the process of adjusting the lower support mold 3 to enter the receiving frame 2 through the height adjustment component, the four positioning plates 8 are reset under the support of the four second elastic support members, and the four sides of the copper clad laminate are limited, so that the copper clad laminate is automatically adjusted and positioned in the process of moving the copper clad laminate to the cold pressing station;

[0044] Cold pressing treatment: The copper clad laminate is cold pressed by the upper die assembly, and during the cold pressing process, the copper clad laminate drives the movable pressure platform 10 and the copper clad laminate into the molding cavity 301 under the pressure of the upper die assembly, and the positioning plate 8 moves synchronously with the clearance seat 7. Then, when the die assembly continues to press, the positioning plate 8 enters the clearance cavity 502 under the pressure, so as to always keep the side of the copper clad laminate limited during the cold pressing process;

[0045] Unloading of copper clad laminate: cancel the pressing of the die assembly, adjust the lower support die 3 to move out of the receiving frame 2 through the height adjustment assembly, and push the cold-pressed copper clad laminate out of the receiving frame 2, and under the linkage of the linkage assembly, the four positioning plates 8 are linked to move, so that the positioning plates 8 keep a certain distance from the copper clad laminate, and under the support of the first elastic support member 9, the yield seat 7 and the movable pressure platform 10 will move upward, thereby pushing the copper clad laminate out of the molding cavity 301, thereby providing a taking space, and facilitating the removal of the copper clad laminate;

[0046] During the entire cold pressing process, by adjusting the positions of the four positioning plates 8, it is achieved to provide installation space when installing the copper clad laminate. In the process of moving the copper clad laminate to the cold pressing station, the four positioning plates 8 are used to provide limit support from the four side directions of the copper clad laminate, and the copper clad laminate is automatically adjusted and positioned so that it is positioned in the cold pressing position.

[0047] It should be further explained that, during the cold pressing process, the positioning plate 8 in the clamping positioning position is above the clearance cavity 502, and the die assembly can press the positioning plate 8 downward at the same time. The positioning plate 8 enters the clearance cavity 502 as the die assembly is pressed, and the positioning plate 8 always maintains a limit on the side wall of the copper clad laminate, which is beneficial to prevent the copper clad laminate from sliding sideways during the cold pressing process.

On the other hand, the positioning plate 8 is indirectly supported to maintain the positioning plate 8 at the upper position of the lower support mold 3.

[0049] like Figure 4 and Figure 5 As shown, as an embodiment, when the positioning plate 8 has completed the positioning of the copper-clad laminate, the bottom of the positioning plate 8 faces the clearance cavity 502, and a guiding slope 801 is provided at the bottom of the positioning plate 8. It should be understood that during the cold pressing process, the positioning plate 8 in the clamping and positioning position is above the clearance cavity 502, and the die assembly can press the positioning plate 8 downward at the same time. Under the action of the guiding slope 801, the slight deviation position between the positioning plate 8 and the clearance cavity 502 can be corrected, which is helpful to prevent the deviation from causing the positioning plate 8 to be unable to enter the clearance cavity 502.

[0052] It should be understood that in the process of adjusting the lower support mold 3 to move out of the accommodating frame 2 by the height adjustment component, the movable threaded rod 12 will move upward on the surface of the fixed threaded rod 15, and under the action of the thread, the movable threaded rod 12 will rotate, and then the external thread 1201 of the movable threaded rod 12 drives the linkage frame 13 to approach the lower support mold 3, and the linkage frame 13 simultaneously drives the four linkage rails 14 to move relative to the lower support mold 3, and the guide groove rail acts on the linkage pin 24, so that the linkage pin 24 pulls the second elastic support member, and the second elastic support member simultaneously pulls the positioning plate 8, so that a shelf space is reserved between the four positioning plates 8, which is convenient for installing the copper clad plate, and also convenient for unloading the copper clad plate. In the process of pushing the cold-pressed copper clad plate out of the accommodating frame 2, the copper clad plate is pushed out of the installation molding cavity, and the limit is cancelled to reserve a picking space;

[0053] Adjust the positioning: adjust the lower support mold 3 into the containing frame 2 through the height adjustment component, and link the four elastic support members to move toward the copper clad laminate, so as to automatically limit the support of the copper clad laminate in the cold pressing station.

[0054] like Figure 5 , Figure 7 , Figure 8 and Fig. 9 As shown, as an embodiment, the second elastic support member includes: a plug-in rod 16, which is plugged into the positioning plate 8, and after passing through the connecting end 702, it is slidably plugged into the plug-in end 1301 at the corresponding position; a support spring 17, which is sleeved on the surface of the plug-in rod 16, and the two ends are respectively fixedly connected to the connecting groove 703 and the positioning plate 8; a limit plate 18, which is fixedly connected to the end of the plug-in rod 16 close to the positioning plate 8.
