DETAILED DESCRIPTION

[0015] The utility model will be further described below in conjunction with the accompanying drawings.

[0016] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] like Figure 1 , 2As shown in FIG. 3 , a multilayer board pressing device comprises a device frame 1, on which is a pressing platform 2, on which is mounted a downward telescopic cylinder 3, a pressing head 31 is connected to the bottom of the telescopic cylinder, and a pressing mold 4, wherein the pressing mold comprises a lower mold 42 and an upper mold 41, wherein the lower mold has a molding cavity 421 on the top, and the upper mold has a molding block facing downward, wherein the molding block and the molding cavity are a matching structure, wherein the lower mold is mounted on the pressing platform, and the upper mold is mounted under the pressing head; wherein the upper mold is characterized in that a cavity 411 is provided around the upper mold, and a heating tube 3 is installed in the cavity, and the heating tube is connected to a power source via a control device.

[0018] Design principle: During the use of the utility model, first, the raw material is placed in the molding cavity for pressing, which is the first pressing. After the first pressing is completed, the heating tube is turned on for heating. At this time, the surrounding part of the upper mold expands due to the heat, and the surrounding part of the upper mold occupies a larger space. The surrounding of the raw material is further squeezed, that is, the second pressing of the raw material is achieved. The second pressing is that the original surrounding part is subjected to greater pressure, which can achieve the production of plates with greater surrounding pressure and higher bearing strength to meet the requirements of some users.

[0019] Furthermore, the molded pressing block includes a peripheral portion 41a and a middle portion 41b, the peripheral portion and the middle portion are integrated with each other, and a heat insulating material layer 6 is provided between the peripheral portion and the middle portion.

[0020] The utility model is arranged in this way, so that the part around the multilayer board that is subjected to greater pressure can be more obvious.

[0021] Furthermore, under the action of the heating tube, when the temperature of the peripheral part rises to a specified temperature, the lower part of the peripheral part and the middle part are smoothly connected, that is, the inner edge of the lower part of the peripheral part has a chamfered structure 41a1.

[0022] The utility model is configured in this way, the surface of the formed multilayer board is smooth, that is, no obvious dividing line appears, for example, the specified temperature is 90°C.

[0023] As an additional technical feature, the telescopic cylinder is connected to a control device, under the action of the control device, the control device automatically turns on the power of the heating tube after turning on the telescopic cylinder for a period of time. For example, the control device used is a PCL control device.

[0024] The utility model is arranged in this way, and has the advantage of higher automation.
