Description

Technical Field

[0001] This utility model relates to the technical field of equipment for processing and manufacturing substitute wood boards, and in particular to a ring-shaped mold for forming substitute wood boards. Background Technology

[0002] "Wood substitute" means "to replace wood," also known as machinable resin board, or wood substitute. With the continuous development of industry (automobiles, ships, toys, home appliances, wind power, etc.), wood substitutes made of polyurethane, epoxy resin, etc., are becoming increasingly widely used. Wood substitutes produced from polyurethane and epoxy resin materials have excellent physical properties such as toughness, hardness, dimensional stability, temperature resistance, compressive strength, and bending strength. The manufacturing method of wood substitutes mainly includes two parts: the first is the preparation method of the hot-melt material for the wood substitute, specifically: first, weigh the raw materials according to the formula, then put them into a mixer and mix them, then add the mixed material to an extruder, heat it to a molten state, and extrude it; the second is the molding method of the wood substitute, specifically: inject the molten hot-melt material into the molding mold, and after the hot-melt material gradually cools in the molding mold, it is formed into a wood substitute, which is then removed from the molding mold.

[0003] However, existing board molding dies have the following drawbacks: First, they typically only mold square-shaped boards, making it difficult to mold ring-shaped boards. Second, existing board molding dies mostly rely on natural cooling, which is too rapid and affects the molding quality, strength, toughness, dimensional stability, temperature resistance, compressive strength, and flexural strength of the boards. This is especially problematic because the resin materials used in board molding vary widely, with different resins exhibiting different properties and requiring different cooling times. Therefore, natural cooling is unsuitable for molding boards with specific properties. Third, after molding, traditional board molding equipment often results in the board sticking to the bottom of the mold, making it difficult to remove the molded board. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a ring-shaped board molding die to address the shortcomings of the prior art. The ring-shaped molding cavity of the molding die can form a ring-shaped board. The molding die can use two arc-shaped heating plates to precisely control the cooling and molding temperature of the ring-shaped board to form ring-shaped boards with different properties.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a ring-shaped wood board forming mold, comprising a base, two arc-shaped heating plates and a ring-shaped forming cavity. The base includes a supporting base plate, on which two arc-shaped grooves are symmetrically arranged. Each arc-shaped groove is respectively installed with one of the aforementioned arc-shaped heating plates. The ring-shaped forming cavity is installed on the supporting base plate and located on the upper side of the arc-shaped heating plates. The upper end of the ring-shaped forming cavity is open. The ring-shaped forming cavity includes a ring-shaped base plate, a circular outer plate and a circular inner plate. The circular outer plate is fixedly installed on the outer edge of the ring-shaped base plate, and the circular inner plate is fixedly installed on the inner edge of the ring-shaped base plate.

[0006] The beneficial effects of this utility model are as follows: First, because this utility model has an annular forming cavity with an open upper end, the annular forming cavity includes an annular base plate, a circular outer plate, and a circular inner plate. The circular outer plate is fixedly installed on the outer edge of the annular base plate, and the circular inner plate is fixedly installed on the inner edge of the annular base plate. Therefore, this utility model's annular forming cavity can form annular substitute wood boards. Second, because this utility model has two symmetrically arranged arc-shaped grooves on the supporting base plate, and each arc-shaped groove is equipped with an arc-shaped heating plate, and the annular forming cavity is installed on the supporting base plate and located on the upper side of the arc-shaped heating plate, this utility model can conveniently control the cooling and forming temperature and forming speed through the arc-shaped heating plate. It can accurately control the cooling and forming time of the substitute wood board according to different performance properties, so that the strength, toughness, dimensional stability, temperature resistance, compressive strength, and bending strength of the substitute wood board all reach the best performance.

[0007] As a further explanation of this utility model: In the above technical solution, the supporting base plate is provided with two first air holes for inputting compressed air, located in the area between two arc-shaped grooves. The annular base plate is provided with two second air holes, which correspond to and are connected to the first air holes. Compressed air input from the first air holes can be injected into the annular molding cavity through the second air holes. This utility model can use the first and second air holes to inject compressed air into the annular molding cavity, causing the substitute wood board to separate from the annular base plate through compressed air, preventing the substitute wood board from sticking to the annular base plate, and facilitating the quick removal of the molded substitute wood board from the annular molding cavity.

[0008] In the above technical solution, a sealing plug mechanism is provided below the supporting base plate corresponding to the first and second air holes. When the annular substitute wood board forming mold is forming the substitute wood board, the sealing plug mechanism blocks the first and second air holes. When it is necessary to remove the formed substitute wood board from the annular substitute wood board forming mold, the sealing plug mechanism opens the first and second air holes, allowing compressed air to enter the annular forming mold cavity from the first and second air holes, thus separating the formed substitute wood board from the annular base plate through compressed air. This utility model, by providing a sealing plug mechanism, can prevent hot-melt material from entering and blocking the first and second air holes during the forming of the substitute wood board.

[0009] In the above technical solution, the sealing plug mechanism includes a cylinder and a sealing plug. The cylinder rod extends upward, and the sealing plug is installed on the upper end of the cylinder rod. The shape of the sealing plug matches the hole walls of the first and second air holes. This utility model, by setting a cylinder and a sealing plug, can automatically seal or open the first and second air holes under the driving action of the cylinder.

[0010] In the above technical solution, the base includes a metal frame, and the supporting base plate is fixedly installed within the metal frame. Using a metal frame ensures a stable installation of the supporting base plate.

[0011] In the above technical solution, the arc-shaped heating plate is an infrared heating plate or a mica heating plate that can adjust the heating temperature. The heating temperature of the infrared heating plate or the mica heating plate is easy to control and can be controlled within 100 degrees Celsius to meet the molding temperature requirements of the wood board.

[0012] In the above technical solution, the circular outer perimeter plate is composed of four arc-shaped outer perimeter plates spliced ​​together, and the circular inner perimeter plate is composed of four arc-shaped inner perimeter plates spliced ​​together. This structure makes the circular outer perimeter plate and the circular inner perimeter plate easy to manufacture and assemble.

[0013] In the above technical solution, the outer diameter of the circular outer plate is 1560mm, the inner diameter of the circular outer plate is 1500mm, the outer diameter of the circular inner plate is 1060mm, and the inner diameter of the circular inner plate is 1000mm. This structure ensures that the circular outer and inner plates have optimal thickness dimensions when molding specific annular substitute wood boards, thus controlling costs while ensuring the annular molding cavity has good strength.

[0018] The structural and working principles of this utility model will be further described in detail below with reference to the accompanying drawings.

[0019] like Figures 1-4 As shown, this utility model is a ring-shaped wood board forming mold, including a base 1, two arc-shaped heating plates 2 and a ring-shaped forming cavity 3. The base 1 includes a supporting base plate 11, and two arc-shaped grooves 12 are symmetrically arranged on the supporting base plate 11. Each arc-shaped heating plate 2 is installed in each arc-shaped groove 12. The ring-shaped forming cavity 3 is installed on the supporting base plate 11 and located on the upper side of the arc-shaped heating plates 2. The upper end of the ring-shaped forming cavity 3 is open. The ring-shaped forming cavity 3 includes a ring-shaped base plate 31, a circular outer plate 32 and a circular inner plate 33. The circular outer plate 32 is fixedly installed on the outer edge of the ring-shaped base plate 31, and the circular inner plate 33 is fixedly installed on the inner edge of the ring-shaped base plate 31. The annular molding cavity 3 of this invention can form annular substitute wood boards. Because the base 1 has two symmetrically arranged arc-shaped grooves 12 on its supporting base plate 11, and each arc-shaped heating plate 2 is installed in one of these grooves, and the annular molding cavity 3 is installed on the supporting base plate 11 and located above the arc-shaped heating plate 2, this invention can easily control the cooling and molding temperature and molding speed through the arc-shaped heating plate 2. It can precisely control the cooling and molding time of the substitute wood board according to different properties of the substitute wood material, so that the strength, toughness, dimensional stability, temperature resistance, compressive strength, and bending strength of the substitute wood board all reach optimal performance.

[0020] like Figures 1-3As shown, the supporting base plate 11 has two first air holes 13 for inputting compressed air, located in the area between two arc-shaped grooves 12. The annular base plate 31 has two second air holes 34, which correspond to and are connected to the first air holes 13. Compressed air input from the first air holes 13 can be injected into the annular molding cavity 3 through the second air holes 34. A sealing ring is provided at the connection between the second air holes 34 and the first air holes 13 to prevent air from leaking down from the connection between the second air holes 34 and the first air holes 13. This invention can use the first air holes 13 and the second air holes 34 to inject compressed air into the annular molding cavity 3, so that the substitute wood board is separated from the annular base plate 31 by compressed air, preventing the substitute wood board from sticking to the annular base plate 31, and making it convenient for a robot arm with a suction cup to quickly remove the molded substitute wood board from the annular molding cavity 3. In addition, the present invention uses an arc-shaped heating plate 2, which makes it easy to position the first air hole 13 and the second air hole 34 in the area between the two arc-shaped heating plates 2.

[0021] like Figures 1-3 As shown, corresponding to the first air hole 13 and the second air hole 34, a sealing plug mechanism 4 is provided below the supporting base plate 11. When the annular substitute wood board forming mold is forming the substitute wood board, the sealing plug mechanism 4 blocks the first air hole 13 and the second air hole 34. When it is necessary to remove the formed substitute wood board from the annular substitute wood board forming mold, the sealing plug mechanism 4 opens the first air hole 13 and the second air hole 34, allowing compressed air to enter the annular forming mold cavity 3 from the first air hole 13 and the second air hole 34, so that the formed substitute wood board is separated from the annular base plate 31 by compressed air. By setting the sealing plug mechanism 4, this utility model can prevent hot melt material from entering the first air hole 13 and the second air hole 34 and blocking the first air hole 13 and the second air hole 34 when the annular substitute wood board forming mold is forming the substitute wood board.

[0022] like Figures 1-3 As shown, the sealing plug mechanism 4 includes a cylinder 41 and a sealing plug 42. The cylinder 41 rod extends upward, and the sealing plug 42 is installed on the upper end of the cylinder 41 rod. The shape of the sealing plug 42 matches the hole walls of the first air hole 13 and the second air hole 34. This invention, by setting up the cylinder 41 and the sealing plug 42, allows the sealing plug 42 to automatically seal or open the first air hole 13 and the second air hole 34 under the driving action of the cylinder 41.

[0023] like Figures 1-3 As shown, the base 1 includes a metal frame 14, and the supporting base plate 11 is fixedly installed within the metal frame 14. The use of the metal frame 14 ensures the stable installation of the supporting base plate 11.

[0024] In a preferred embodiment of this invention, the arc-shaped heating plate 2 is an infrared heating plate or a mica heating plate with adjustable heating temperature. The heating temperature of the infrared heating plate or mica heating plate is easy to control and can be kept below 100 degrees Celsius to meet the molding temperature requirements of the substitute wood board. Generally, after the molten substitute wood board material is poured into the annular molding cavity 3, the infrared heating plate or mica heating plate is maintained at a temperature close to 100 degrees Celsius. Then, according to the properties of the substitute wood board material, the temperature of the infrared heating plate or mica heating plate is gradually reduced within a set time period, so that the substitute wood board is cooled and molded in the best cooling manner.

[0025] like Figure 4 As shown, the circular outer perimeter plate 32 is composed of four arc-shaped outer perimeter plates 321 spliced ​​together, and the circular inner perimeter plate 33 is composed of four arc-shaped inner perimeter plates 331 spliced ​​together. This structure makes the circular outer perimeter plate 32 and the circular inner perimeter plate 33 easy to manufacture and assemble.

[0026] like Figure 3 As shown, the outer diameter Φ1 of the circular outer plate 32 is 1560mm, the inner diameter Φ2 of the circular outer plate 32 is 1500mm, the outer diameter Φ3 of the circular inner plate 33 is 1060mm, and the inner diameter Φ4 of the circular inner plate 33 is 1000mm. This structure ensures that the circular outer plate 32 and the circular inner plate 33 have optimal thickness dimensions when molding specific annular substitute wood boards, thus controlling costs while ensuring that the annular molding cavity 3 has optimal strength.

[0027] The above description is merely a preferred embodiment of this utility model. Any minor modifications, equivalent changes, and alterations made to the above embodiments based on the technical solution of this utility model shall fall within the scope of the technical solution of this utility model.
