It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.

In the description of the present utility model, it should be understood that the terms "upper," "lower," "left," "right," and the like indicate an orientation or a positional relationship based on that shown in the drawings, and are merely for convenience of description and for simplifying the description, and do not indicate or imply that the apparatus or element in question must have a specific orientation, as well as a specific orientation configuration and operation, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. In the description of the present utility model, unless otherwise indicated, the meaning of "a plurality" is two or more.

Referring to fig. 1 and 2, the utility model provides a special-shaped triamine board high-frequency heating molding press, which comprises a frame 1, a hydraulic assembly 2 and a mold assembly 3, wherein the hydraulic assembly 2 and the mold assembly 3 are arranged on the frame 1; the frame 1 comprises a base 11 and a support frame 12 arranged on the base 11, and the hydraulic component 2 is fixed on the support frame 12; the die assembly 3 comprises an upper die 31 and a lower die 32, the upper die 31 is fixedly connected with the hydraulic assembly 2, and the lower die 32 is fixed on the base 11; also included is a high frequency heater 4 connected to the die assembly 3. The high-frequency heater 4 forms a high-frequency electric field in the mold assembly 3, and when the planar triamine plate is placed between the upper mold 31 and the lower mold 32, molecules in the planar triamine plate are rotated or vibrated at a high speed, and friction and collision between the molecules occur, thereby achieving the purpose of heating. When the planar triamine sheet is heated, the brittleness of the planar triamine sheet is reduced, the flexibility is improved, and the melamine resin is softened, and at this time, the upper die 31 is gradually pressed down by the hydraulic cylinder 22, so that the planar triamine sheet is gradually bent, cooled, and fixed for molding.

Specifically, the mold assembly 3 has different shapes according to the production requirement, and the mold assembly 3 for manufacturing the strip curved veneer is shown in fig. 1. The bottom surface of the upper mold 31 or the middle of the top surface of the lower mold 32 may also be provided with different convex structures, so that a veneer having different stereoscopic effects on the surface is produced by molding.

Referring to fig. 3, in one preferred embodiment, the hydraulic assembly 2 includes an upper platen 21, a plurality of hydraulic cylinders 22, and a pump assembly 23 connected to the plurality of hydraulic cylinders 22; the lifting ends of the hydraulic cylinders 22 are fixedly connected with the top of the upper pressing plate 21; the upper die 31 is fixed below the upper platen 21. Specifically, the multiple hydraulic cylinders 22 may be controlled separately by the linkage pump assembly 23 to adjust the pressure of the different hydraulic cylinders 22. When different types of products are required to be produced, the hardness or stiffness of different parts of the products are different, the pressure required to be applied during mould pressing is required to be adjusted in real time, the pressing pressure of a plurality of hydraulic cylinders can be respectively controlled, and the hydraulic cylinders can be matched with mould components 3 with different shapes better to produce special-shaped triamine boards with different specifications.

Referring to fig. 3, in a preferred embodiment, a plurality of hydraulic cylinders 22 are arranged linearly, and include two side cylinders 221 respectively located at two ends and a plurality of master cylinders 222 disposed between the two side cylinders 221; the side cylinder 221 and the main cylinder 222 are connected to the pump-linkage assembly 23, respectively. The special-shaped veneer with the large length is suitable for production. Taking the production of a strip-shaped curved surface veneer as an example, the deformation resistance of the two ends of the strip-shaped planar veneer is weaker than that of the middle part of the planar veneer, so that when in mould pressing, the master cylinder 222 positioned in the middle part needs to adopt larger downward pressure, and the downward pressure of the side cylinders 221 at the two ends is smaller than that of the master cylinder 222. Specifically, in one embodiment, the master cylinders 222 are provided with three in total, the three master cylinders 222 are operated in synchronization, and the two side cylinders 221 are operated in synchronization.

Referring to fig. 3, the supporting frame 12 includes a transverse supporting structure 121 and vertical supporting structures 122 respectively disposed on two sides of the transverse supporting structure 121, and the vertical supporting structures 122 extend downward and are fixedly connected with the base 11. The master cylinder 222 and the side cylinder 221 are each fixed to the cross support structure 121.

Referring to fig. 4-6, in a preferred embodiment, the vertical support structure 122 has high conductivity metal risers 123 disposed on the inner side walls thereof; the two sides of the upper pressing plate 21 are respectively provided with a high-conductivity connecting piece 124, and the high-conductivity connecting piece 124 is in sliding connection with a high-conductivity metal riser 123; the top of the base 11 is fixed with a high-conductivity metal bottom plate 125, and the lower die 32 is fixed on the high-conductivity metal bottom plate 125; the bottom of the high-conductivity metal riser 123 is connected to the high-conductivity metal base 125; the positive electrode wire 41 of the high-frequency heater 4 is connected to the upper die 31, and the negative electrode wire 42 is connected to the lower die 32.

Specifically, the current flows out from the positive electrode wire 41 of the high-frequency heater 4, then sequentially passes through the upper die 31, the upper pressing plate 21, the high-conductivity connecting piece 124, the upper part of the high-conductivity metal riser 123, the bottom of the high-conductivity metal riser 123, the high-conductivity metal bottom plate 125, the lower die 32 and the negative electrode wire 42, and finally returns to the high-frequency heater 4 through the negative electrode wire 42 to form a loop. The above structure can prevent the current generated by the high-frequency heater 4 from diffusing to the frame 1, the hydraulic assembly 2 and other electrical equipment, and concentrate the current on the die assembly 3.

Preferably, the high conductivity connector 124 abuts against the high conductivity metal riser 123, and the high conductivity connector 124 is kept in contact with the high conductivity metal riser 123 during the lifting of the upper platen 21.

Preferably, in one embodiment, a copper sheet is further connected between the high conductivity metal base 125 and the top surface of the lower die 32. Since the lower die 32 is detachable as needed, the connection between the lower die 32 and the high-conductivity metal base 125 is not tight enough and the conductivity is not good enough. If the bottom of the lower die 32 is made of a light material with lower conductivity, current is not easy to reach the top surface of the lower die 32, and by arranging a copper sheet, the current communication between the high-conductivity metal bottom plate 125 and the top surface of the lower die 32 can be enhanced.
