Description

Technical Field

[0001] This utility model belongs to the field of aluminum-based copper clad laminate processing technology, specifically relating to a hot press for pressing aluminum-based copper clad laminates. Background Technology

[0002] Aluminum-based copper clad laminate, also known as aluminum substrate, is a type of raw material. It is a sheet material made by impregnating electronic fiberglass cloth or other reinforcing materials with resin or single resin as an insulating adhesive layer, covering one or both sides with copper foil, and then hot-pressing it. During processing, an auxiliary pressing thermoforming machine is required for production. In the existing technology, the pressing thermoforming machine uses an upper mold that moves up and down with the machine while the lower mold is fixed. After hot pressing is completed, the upper mold is lifted upwards, and personnel reach into the space between the upper and lower molds to retrieve the material. This not only poses a significant safety hazard, as personnel are easily injured or burned when retrieving the material, but also, in order to keep the overall thermoforming machine compact, the gap between the upper and lower molds is small, which is not conducive to the handling of workpieces. The convenience of use is limited, thus restricting its applicability and practicality. Summary of the Invention

[0003] The purpose of this utility model is to provide a hot press for laminating aluminum-based copper-clad laminates that has a reasonable structural design and is conducive to improving ease of use.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example

[0024] See Figure 1 and Figure 2 As shown, a hot press for laminating aluminum-based copper-clad laminates includes a base 1, a hot press platform 2 and a support 3 fixed on the base, a cylinder 4 fixed on the support, a mounting seat 12 fixed on the piston shaft of the cylinder, an upper hot press mold 5 fixed on the bottom surface of the mounting seat, and a lower hot press mold 6 disposed on the hot press platform. In this embodiment, a plurality of heating tubes 13 are disposed inside the mounting seat. The base, hot press platform, and support are all conventional structures of the prior art, and therefore are not described in detail. Furthermore, the upper and lower hot press molds are set according to processing needs and can be replaced.

[0025] The hot-pressing platform is provided with a strip-shaped groove 7, and a strip-shaped rotating seat 9 is rotatably connected to the groove via a shaft 8. An electric telescopic rod 10 is connected to the base via a pin. In this embodiment, the electric telescopic rod is a conventional structure of the prior art, simply applied, and therefore not described in detail. A positioning structure 11 is provided on the strip-shaped rotating seat. One edge of the bottom surface of the lower hot-pressing die is attached to the strip-shaped rotating seat and clamped and positioned by the positioning structure. The extension and retraction of the electric telescopic rod causes the lower hot-pressing die to rotate at an angle via the strip-shaped rotating seat. Through the above structure, the electric telescopic rod can drive the strip-shaped rotating seat to rotate around the shaft, simultaneously causing the lower hot-pressing die to rotate at an angle. Specifically, in practical applications, the rotation angle of the lower hot-pressing die is 20-45 degrees. The tilting of the lower hot-pressing die not only facilitates the loading and unloading of workpieces but also prevents accidental downward pressure from the upper hot-pressing die, and also prevents hand burns, thus improving safety and reliability.

[0026] In this embodiment, the positioning structure 11 includes a positioning support plate 111 and a locking screw 112. During installation, the bottom surface of the positioning support plate is fixed to both ends of the strip-shaped rotating seat. The height of the positioning support plate is less than the height of the hot-pressing die. The bottom surface of the hot-pressing die is attached to the surface of the strip-shaped rotating seat and is located between the two positioning support plates, and is fixed by the locking screw. This structure facilitates the disassembly and replacement of the hot-pressing die, while also ensuring that the hot-pressing die can rotate at an angle with the strip-shaped rotating seat as a fulcrum, thus improving its applicability and practicality.

[0027] In this embodiment, a power connection 14 and a control switch 15 are fixed on the base. The control switch includes an electric telescopic rod control switch and a cylinder start / stop button. The control switches enable control of the electric telescopic rod and the cylinder.

[0028] This utility model has the following positive effects: The structure of this utility model is reasonably designed. It is equipped with a strip-shaped rotating seat and an electric telescopic rod. After hot pressing is completed, the lower hot pressing mold can be tilted at a certain angle by the electric telescopic rod, which is conducive to the handling of workpieces. At the same time, since the lower hot pressing mold is tilted, it can also prevent the upper hot pressing mold from falling due to misoperation, and it can also prevent hands from being burned. It can improve the safety of use, is convenient to operate, stable and reliable in use, and has strong practicality.

[0029] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0030] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
