Description

Technical Field

[0001] The utility model relates to the field of aluminum substrate die-casting, in particular to an aluminum-based copper-clad plate die-casting device. Background Art

[0002] Aluminum-based copper-clad laminates play an important role in the electronics industry, especially in the manufacture of printed circuit boards (PCBs), due to their excellent thermal conductivity, mechanical strength, and electrical insulation properties. As electronic equipment develops towards miniaturization and high performance, higher requirements are placed on the thickness and uniformity of aluminum-based copper-clad laminates. Traditional production processes are difficult to use when processing multi-layer composite materials, especially when multiple layers, that is, more than 100 sheets of aluminum, adhesive, and copper layers need to be compressed at the same time. Existing die-casting equipment and technology can usually only process a small number of sheets, and it is difficult to ensure that multiple batches of sheets are compressed at the same time, resulting in low production efficiency and unable to meet the needs of large-scale production. In addition, the degree of automation is not high and it relies on manual operation, which increases production costs and ultimately affects product quality.

[0003] Therefore, it is of great practical significance to develop a device that can efficiently and uniformly compress a large number of multi-layer aluminum-based copper-clad laminates into thin sheets. Utility Model Content

The screw rod is arranged at the output end of the pressure plate drive motor, the connecting block is threadedly connected to the screw rod, and the two ends of the double-headed hinge are respectively hinged to the layered pressure plate and the connecting block.

[0008] Based on the above, the beneficial effect of the pressure plate driving motor is to drive the screw rod to operate; the beneficial effect of the screw rod is to drive the connection block to move; the beneficial effect of the connection block is to drive the layered pressure plate to press down.

[0009] Furthermore, the four corners of the platform frame are each provided with an expansion hydraulic rod, and the upper end of the expansion hydraulic rod is connected to the upper hydraulic mechanism for driving the upper hydraulic mechanism to move upward when the layered pressure plate is added.

[0010] Based on the above, the beneficial effect of extending the hydraulic rod is to allow the position of the upper hydraulic mechanism to be automatically adjusted when the number of layered press plates is increased.

[0011] Furthermore, the pressing mechanism also includes a temperature sensor for monitoring the temperature of the pressing area in real time.

[0012] Furthermore, a control box is provided on the platform frame, and the control box is electrically connected to the upper hydraulic mechanism, the lower hydraulic mechanism, the pressure plate drive assembly and the temperature sensor respectively.

DETAILED DESCRIPTION

[0018] like Figure 1 As shown, an aluminum-based copper-clad laminate die-casting device includes a carrier frame 1, in which an upper hydraulic mechanism 2, a lower hydraulic mechanism 3 and a pressing mechanism 5 are arranged. The upper hydraulic mechanism 2 and the lower hydraulic mechanism 3 are respectively located at the upper and lower ends of the pressing mechanism 5, and the pressing mechanism 5 includes a support plate 51, guide columns 52 arranged at the four corners of the support plate 51, at least one layered pressing plate 53 and a pressing plate driving assembly 54 respectively located on both sides of the layered pressing plate 53, the four corners of the layered pressing plate 53 are slidably connected to the guide columns 52, and the two pressing plate driving assemblies 54 are hinged to the two sides of the layered pressing plate 53 through double-headed hinges 544, a number of aluminum substrates 100 to be die-cast are placed between the layered pressing plate 53 and the support plate 51, and a number of aluminum substrates 100 to be die-cast are placed between every two layered pressing plates 53, the upper hydraulic mechanism 2 is connected to the uppermost layered pressing plate 53, and the lower hydraulic mechanism 3 is connected to the support plate 51.

[0019] The pressure plate drive assembly 54 also includes a pressure plate drive motor 541, a screw rod 542 and a connecting block 543. The screw rod 542 is arranged at the output end of the pressure plate drive motor 541, and the connecting block 543 is threadedly connected to the screw rod 542. The two ends of the double-headed hinge 544 are respectively hinged to the layered pressure plate 53 and the connecting block 543.

[0020] The four corners of the platform frame 1 are each provided with an expansion hydraulic rod 4 , the upper end of the expansion hydraulic rod 4 being connected to the upper hydraulic mechanism 2 for driving the upper hydraulic mechanism 2 to move upward when the layered pressing plate 53 is added.

[0021] The pressing mechanism 5 further includes a temperature sensor for real-time monitoring of the temperature of the pressing area.

[0022] A control box 6 is provided on the platform frame 1 , and the control box 6 is electrically connected to the upper hydraulic mechanism 2 , the lower hydraulic mechanism 3 , the pressure plate driving assembly 54 and the temperature sensor respectively.

[0023] The stage frame 1 is further provided with a high-temperature cavity 7 , and the pressing mechanism 5 is located in the high-temperature cavity 7 .

[0024] In summary, the specific implementation of the present invention is as follows: First, the operator places the aluminum substrate 100 between the support plate 51 and the layering plate 53 as needed. When multiple layers of the aluminum substrate 100 are to be die-casted, the aluminum substrates 100 of other layers are placed between every two layering plate 53 as needed. In this embodiment, these aluminum substrates 100 are composite materials composed of aluminum layers, adhesive layers, and copper layers.

[0025] Start the pressing plate driving motor 541, which drives the connecting block 543 to move via the screw rod 542. The connecting block 543 drives the layered pressing plate 53 to slide along the guide column 52 via the double-headed hinge 544, thereby preliminarily clamping the aluminum substrate 100.

[0026] The high-temperature chamber 7 begins to apply high temperature to the aluminum substrate 100, which helps to make the bonding between the plates stronger. The temperature sensor detects the temperature of the pressing area in real time and feeds the signal back to the control box 6 to ensure that the temperature remains within the set range during the pressing process.

[0027] At the same time, the upper hydraulic mechanism 2 is driven by the control box 6, and the hydraulic oil enters the piston, pushing the uppermost layered pressing plate 53 connected to it to move downward, while the lower hydraulic mechanism 3 keeps the support plate 51 in a fixed position, thus forming a process of applying pressure to the middle aluminum substrate 100 from both the upper and lower directions.

[0028] After the pressing is completed, the upper hydraulic mechanism 2 retracts, and the pressure plate drive assembly 54 drives the layered pressure plate 53 to return to the initial position. The external clamping mechanism can remove the pressed aluminum substrate 100 from the support plate 51 and each layered pressure plate 53, and replace the new plate to be die-cast to enter the next cycle.

[0029] The above description is only the optimal solution embodiment of the present invention and is not intended to limit the present invention. Various modifications or replacements of the present invention made by those skilled in the art without departing from the essence and protection scope of the present invention should also be within the protection scope of the present invention.
