Description

Technical Field

[0001] This invention relates to the field of straw board processing technology, specifically to molds for straw boards. Background Technology

[0002] Straw board is an environmentally friendly engineered wood product. Its core raw material is derived from the straw left after harvesting crops such as rice, wheat, and corn, encompassing agricultural waste such as stalks and wheat straw. Straw board can be used alone or combined with wood fiber, bamboo fiber, and other materials, making it suitable for various home furnishing scenarios. From cabinetry to decoration, it leverages its environmental advantages. Currently, some straw board manufacturing molds typically use a pressing method at a certain temperature. However, this method is time-consuming because moisture in the center of the straw board is difficult to expel. Often, the periphery dries and solidifies while the inner core remains moist, leading to bulging or even cracking. To solve this problem, the pressing time is usually extended to ensure the moisture in the straw board's core is expelled, thus resulting in a longer production cycle. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a mold for straw boards, which solves the problem that the existing pressing method for making straw boards results in slow moisture removal and a long overall production time.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: a mold for straw board, including a mold groove, a pressure plate provided in the mold groove, a plurality of holes opened in the side wall of the mold groove, the lower wall surface of the mold groove being an upper concave arched surface and having support frames on both sides, a plane being provided in the middle of the upper wall surface of the pressure plate and inclined surfaces being provided on both sides, and a transition slope being provided between the two ends of the plane and a pair of inclined surfaces.

[0005] Preferably, a pair of fixing plates are fixedly installed on the plane, and each of the pair of fixing plates is provided with a sleeve, and a reinforcing rib is provided between the sleeve and the fixing plate.

[0006] Preferably, the thickness of the pressure plate gradually decreases from the middle to both sides, and a gap is provided between the outer wall of the pressure plate and the inner wall of the mold groove.

[0007] Preferably, the thickness of the lower wall of the mold groove gradually increases from the middle to both sides.

[0008] This invention provides a mold for straw boards, which has the following beneficial effects: the pressing plate is made into a structure that is thick in the middle and gradually thins on both sides, and the lower wall of the mold groove is made into a structure that is thin in the middle and gradually thickens on both sides. This design allows the middle part of the mold groove to heat up first after being heated, while the temperature on both sides of the mold groove heats up more slowly. This allows the moisture in the core of the straw board in the middle of the mold groove to be gradually discharged outward, thereby ensuring that all the moisture in the straw board is discharged, and avoiding the situation where the surrounding area is dry while the core is damp.

[0009] During the production of straw boards, adhesive is added to the middle. This technical solution allows the adhesive to dry gradually from the inner core of the straw board outwards, effectively avoiding the problem of unevenness in the straw board caused by uneven drying of the adhesive.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Please see Figure 1-2 The present invention provides a technical solution: a mold for straw board, including a mold groove 1, a pressure plate 2 is provided in the mold groove 1, a plurality of holes 6 are opened in the side wall of the mold groove 1, the lower wall surface of the mold groove 1 is an upper concave arched surface 8 and a support frame 7 is provided on both sides, a plane 10 is provided in the middle of the upper wall surface of the pressure plate 2 and inclined surfaces 9 are provided on both sides respectively, and a transition slope 11 is provided between the two ends of the plane 10 and the pair of inclined surfaces 9; The upper wall of the mold groove 1 is flat and is used to support the straw board. The design of the concave arched surface 8 of the lower wall makes the mold groove 1 a structure that is thin in the middle and gradually thickens on both sides. This allows the middle of the mold groove 1 to be heated first, and the sides to be heated later, forming a structure with a temperature gradient where the heat in the middle is higher than that on both sides. The pressure plate 2 is thicker in the middle and thinner on both sides, which further enhances the temperature difference formation within the mold groove 1.

[0015] Furthermore, a pair of fixing plates 3 are fixedly installed on the plane 10, and a sleeve 4 is provided on each of the pair of fixing plates 3. A reinforcing rib 5 is provided between the sleeve 4 and the fixing plate 3. Sleeve 4 is used to connect the device that controls the lifting and lowering of pressure plate 2. This device is usually a hydraulic cylinder. The equipment and methods used are conventional techniques, so there is no need to describe them in detail.

[0016] Furthermore, the thickness of the pressure plate 2 gradually decreases from the middle to both sides, and a gap is provided between the outer wall of the pressure plate 2 and the inner wall of the mold groove 1.

[0017] Furthermore, the thickness of the lower wall of the mold groove 1 gradually increases from the middle to both sides.

[0018] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known in the field. The working principle and process are mainly described below.

[0019] Example: In use, the straw board is located in the mold groove 1 and pressed down by the pressure plate 2. A heat source is used to heat the area below the mold groove 1. Since the lower wall of the mold groove 1 is thinner in the middle and gradually thicker on both sides, the straw board in the mold groove 1 is heated first in the middle and then gradually heated on both sides. The pressure plate 2 is thicker in the middle and gradually thinner on both sides, so the heat dissipation in the middle is slower, while the heat dissipation on both sides is gradually faster. This creates a temperature difference between the mold groove 1 and the pressure plate 2, forming a high-temperature zone in the middle and a gradually decreasing temperature zone on both sides. This temperature difference helps the moisture in the middle to move to both sides, thus achieving a situation where both the middle and the outside are dry and avoiding dampness in the middle layer.
