[0002] A foaming machine is a device that makes foam from an aqueous solution of a certain concentration of a foaming agent. The foaming agent itself cannot automatically become foam and must be mechanically acted upon by the foaming machine to become foam. Foam products are now indispensable daily necessities, such as shoes or cushions, which are even more necessities in life. Therefore, the foaming machine has become one of the most widely used production machinery in industrial production.

[0003] The large EVA foaming machines commonly used at present all adopt a single main cylinder structure. This large foaming machine with a single cylinder structure will have the following problems in actual use. First, since the main cylinder is set in the middle, when the main cylinder presses the movable beam upward, it will cause uneven force on the frame, and the clamping force in the center area of ​​the frame and the clamping force in the surrounding areas of the frame will be inconsistent, which will eventually shorten the fatigue life of the frame. Second, this large foaming machine with a single cylinder structure mainly relies on the heat emitted by the pressure plate for heating during foaming, which makes the heating uneven during the foaming process. The foamed finished product will have quality problems such as uneven density and thickness.

[0004] Therefore, the utility model provides a foaming machine with good constant temperature performance to solve the problems raised in the above background technology. Utility Model Content
