[0002] Noise is one of the main environmental pollutions nowadays, and the acoustic environment of buildings is receiving more and more attention. Therefore, it is necessary to select appropriate materials to absorb and insulate the buildings to achieve the effect of acoustic environment control. The most important material is the sound insulation board. In the process of producing the sound insulation board, the molten composite material will be solidified through the molding equipment to form the sound insulation board.

[0003] However, the existing sound insulation board molding equipment still has certain defects when used;

[0004] For example, a sound insulation board compression molding equipment proposed in application number CN202211670305.4 includes a base, a bottom plate and a mold base, etc. The base is provided with a bottom plate, and a frame and a mold base are installed on the bottom plate. A bottom mold is provided in the mold base, and a first cylinder is provided on the top of the frame. The movable mold is fixedly connected to the first cylinder, and the movable mold is opposite to the bottom mold.

The movable mold is provided with a vibrator, and the vibrator can make the movable mold vibrate. An adjusting bolt passing through the mold base and the bottom plate is provided at the bottom of the bottom mold. The present invention realizes flexible adjustment of the bottom mold height by cooperating with adjusting bolts and bottom mold and other components, and can realize compression molding of products of different thicknesses without changing the mold, effectively reducing the design and manufacturing costs, and improving the production and processing efficiency during mass production. In actual use, the following problems still exist:

[0005] 1. The equipment cools down the mold by circulating the liquid in the cooling device to achieve the effect of rapid prototyping. However, a separate conveying structure is required for the liquid to circulate, and the kinetic energy of the equipment itself cannot be used to drive the liquid circulation, which reduces the use effect.

[0006] 2. When demolding the solidified sound insulation board, the equipment uses a demolding device to achieve demolding, and after demolding, the solidified sound insulation board is pushed out by a push rod to achieve discharge. The driving of the demolding device requires the lifting and lowering of the movable mold, which causes the demolding structure to be complicated, and the method of pushing the push rod to discharge also has the problem of reduced stability.
