[0007] Furthermore, a rotating motor is installed in the cavity, and the eccentric rotating head is connected to the rotating motor. The rotating motor is connected to a power source through a control device. By operating the control device, the rotating motor drives the eccentric rotating head to change from one station to another.

[0008] The beneficial effect of the utility model is that such a multi-layer board forming mold has the advantage of being able to produce boards with greater surrounding pressure and higher bearing strength to meet the requirements of some users. BRIEF DESCRIPTION OF THE DRAWINGS

[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, a multilayer board forming mold comprises a mold body, and the mold body comprises a lower mold 1 and an upper mold 2, the lower mold has an upper forming cavity 11, the upper mold has a downward forming block 3, and the forming block and the forming cavity are a matching structure; the characteristic is that the forming block comprises a middle block 31 and a surrounding block 32 installed around the middle block, the surrounding block can slide up and down around the middle block, a spring 4 is installed between the surrounding block and the middle block, the spring is a spring that forms an upward movement trend of the surrounding block, there is a hole 311 on the side of the middle block, and an eccentric rotating head 5 is installed in the hole; the eccentric rotating head is rotated, and when the eccentric rotating head is in a station, the eccentric rotating head pushes the surrounding block downward, so that the bottom of the surrounding block and the bottom of the center block are on the same plane, as shown in FIG. Figure 1 As shown; rotating the eccentric rotating head, the eccentric rotating head is in another station, the eccentric rotating head pushes down the surrounding blocks, so that the bottom of the surrounding blocks is lower than the bottom of the center block, as shown Figure 3 shown.

[0018] Method and principle of use. When in use, first, the eccentric rotating head is in one station to press the raw material normally. After pressing once, the eccentric rotating head is changed to another station to press the raw material for the second time. Since the bottom of the surrounding blocks is lower than the bottom of the central block, the surrounding of the raw material can be subjected to greater pressure, and plates with greater surrounding pressure and higher bearing strength can be produced, which can meet the requirements of some users and achieve the purpose of the utility model. In the above scheme, the rotation of the eccentric rotating head can be manually controlled.

[0019] Furthermore, a rotating motor 6 is installed in the cavity, and the eccentric rotating head is connected to the rotating motor. The rotating motor is connected to a power source through a control device. By operating the control device, the rotating motor drives the eccentric rotating head to change from one station to another.

[0020] The above arrangement of the utility model can start the rotating motor to change the working position of the eccentric rotating head, which is more convenient to use.
