[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, this utility model provides a technical solution: a hot press for bamboo products, including a hot press body, a lower mold assembly 1 and an upper mold assembly 2. The lower mold assembly 1 includes a lower module 101, an elastic element is provided in the mold cavity of the lower module 101, and a heating plate 102 is fixed to the bottom wall of the mold cavity of the lower module 101 to heat the mold cavity. A hollowed-out shelf 107 is provided on the top of the elastic element, and protrusions 108 are fixed at the four corners of the shelf 107. Bamboo products are placed on the top of the shelf 107. It should be noted that after the bamboo products are placed on the top of the shelf 107, the height of the protrusions 108 is less than the height of the bamboo products.

[0024] like Figure 3 As shown, the upper mold assembly 2 includes an upper module 201. A mold head 202 is fixed at the bottom of the upper module 201, and the mold head 202 is adapted to the mold cavity of the lower module 101. During hot pressing, the upper module 201 moves downward until the mold head 202 is pressed against the top of the bamboo product. Through holes are provided at the four corners of the upper module 201 and the mold head 202. A pressing head 205 is provided in the through hole. That is, in the initial state, the pressing head 205 is stored in the through hole. It should be noted that the pressing head 205 is located directly above the protrusion 108. In this solution, the bottom end face of the pressing head 205 is flush with the bottom end face of the mold head 202. An electric telescopic rod 204 is fixed in the through hole. The pressing head 205 is fixed to the telescopic end of the electric telescopic rod 204. When the electric telescopic rod 204 retracts, it drives the pressing head 205 to move up and down.

[0025] like Figure 4As shown, the elastic member includes a fixed block 103 fixed with four corners of the mold cavity, an insertion shaft 104 is movably inserted on the fixed block 103, the bottom end of the insertion shaft 104 is fixed with a movable support block 105, and a spring 106 is fixed between the movable support block 105 and the fixed block 103. The storage plate 107 is detachably fixed or placed on the top of the insertion shaft 104.

[0026] As shown in the Figure 4 To achieve rapid cooling of the hot-pressed bamboo product, an air inlet pipe 3 and an air suction pipe 4 are fixed on one side of the lower mold block 101 and communicate with the mold cavity of the lower mold block 101. The air inlet of the air inlet pipe 3 is located at the top of the storage plate 107, and the air suction port of the air suction pipe 4 is located at the bottom of the storage plate 107. The air inlet pipe 3 is connected with an air pump, so that the external air is pumped into the mold cavity through the air inlet pipe 3.

[0027] To recycle the heat in the mold cavity and save energy, a heat exchanger 5 is connected to the pipe body of the air suction pipe 4 to recycle the heat of the hot air flowing out of the mold cavity.

[0028] To promote the rapid cooling of the bamboo product, the pipe body of the air suction pipe 4 extends into the mold cavity of the lower mold block 101. A plurality of air suction holes 401 are formed in the pipe body of the air suction pipe 4, and the diameters of the air suction holes 401 increase from left to right. In this way, the flow rate of the air sucked by the right air suction hole 401 is greater than that of the left air suction hole 401, effectively increasing the flow path of the external air in the mold cavity, and achieving rapid and uniform cooling of the bamboo product.

[0029] As shown in the Figure 3 To enable the top of the bamboo product to be heated sufficiently and facilitate uniform cooling of the bamboo product in the later stage, a cavity 203 is formed in the die head 202, and a plurality of air holes are formed in the bottom plate of the die head 202 and communicate with the cavity 203. In this way, the heat in the mold cavity can enter the cavity 203, so that the heat is heated to the top of the bamboo product through the air holes.

[0030] For the supplement of the present scheme, when in use, the bamboo product is uniformly placed on the top of the storage plate 107. The hydraulic cylinder on the hot press is controlled to elongate by the controller. The upper mold block 201 moves downward until the die head 202 is pressed against the top of the bamboo product. The heating plate 102 is controlled to heat by the controller. After hot pressing for a period of time, the heating plate 102 stops heating. When the bamboo product is hot-pressed, the electric telescopic rod 204 is controlled to elongate by the controller. The abutting head 205 moves downward and is pressed against the protruding block 108 until the bamboo product is separated from the die head 202. At this time, the air pump is started by the controller. The external air enters the mold cavity through the air inlet pipe 3, exchanges heat with the heat in the mold cavity, and is then discharged through the air suction pipe 4, thereby achieving uniform cooling of the bamboo product.

[0031] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
