[0023] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See Figures 1 to 2 The utility model discloses a high-frequency molding machine, including a workbench 10, a forming die 20 and a pressing mechanism. The forming die 20 is located on the workbench 10, and a forming cavity 24 is provided in the forming die 20. A bottom plate 21 and at least two partitions 22 are provided in the forming cavity 24, and the bottom plate 21 and the partition 22 are detachably connected to the forming die 20, and the bottom plate 21 and the at least two partitions 22 are spaced from bottom to top, and the forming cavity 24 is divided into at least three pressing cavities, so as to fill the material 60 through the at least three pressing cavities; and the pressing mechanism includes a pressing seat 30 and a pressing driving member 31, and the pressing seat 30 is arranged above the forming die 20, and the pressing driving member 31 is used to drive the pressing seat 30 to move toward or away from the forming die 20, and extend into the forming cavity 24 when moving toward the forming die 20, so as to press the material 60 and form the material 60.

[0027] On the basis of the above structure, when the high-frequency molding machine in this embodiment is used to produce products that need to be molded (such as plates or plastic floors, etc.), the pressing mechanism can use an existing high-frequency press, the pressing seat 30 is the hot pressing plate 23 of the high-frequency press, and the pressing drive 31 can use a driving motor 40 or a hydraulic drive, etc. In specific use, the bottom plate 21 is first set at the bottom of the molding die 20, and the first layer of material 60 is laid on the bottom plate 21, and then one of the partitions 22 is laid on the first layer of material 60. At this time, the second layer of material 60 can be laid on the partition 22, and then another partition 22 is laid on the second layer of material 60, and finally the third layer of material 60 is laid on the partition 22 on the top layer, so that at least three layers of material 60 are laid alternately in the molding cavity 24. In this way, when the pressing seat 30 moves close to the molding cavity 24 and is pressed above the material 60, at least three products can be molded in the molding cavity 24 at one time to improve processing efficiency.

[0028] After the material 60 is formed into a product, the pressing seat 30 is driven again by the pressing driving member 31 to move away from the forming cavity 24, so as to move it away from the forming mold 20. At this time, the forming mold 20 is moved from the workbench 10 to the demolding area. Since the bottom plate 21 and the two partitions 22 are removable, the operator can take out the formed products in turn and then start the next round of cycle operation.

[0029] It should be noted that the partitions 22 in this embodiment can be set to three, four or more according to actual production needs, so that the molding cavity 24 can be divided into four, five or more pressing cavities. In this way, more layers of materials can be laid in the molding cavity 24 in sequence, so that when the pressing seat 30 moves close to the molding cavity 24 and is pressed on top of the material, four, five or more products can be formed in the molding cavity 24 at one time, further improving processing efficiency.

[0030] In addition, the pressing mechanism in this embodiment can use an existing high-frequency press, the pressing seat 30 is the hot pressing plate 23 of the high-frequency press, and the pressing drive 31 is a driving motor 40 or a hydraulic drive or other driving structure, so that the hot pressing plate 23 applies pressure to the material 60 while heating it, so that the material 60 is tightly combined together in a softened state, thereby improving the pressing effect and allowing the product to be quickly formed.

[0031] Furthermore, a pressing plate 23 is provided in the molding cavity 24 . The pressing plate 23 is pressed on the uppermost portion of the molding cavity 24 after the material 60 is filled into the pressing cavity.

[0032] Specifically, after the third layer of material 60 is laid, if the pressing seat 30 is directly brought into contact with the material 60, the material 60 may be displaced due to vibration or impact, resulting in poor pressing effect. Therefore, in this embodiment, a pressing plate 23 is further provided on the third layer of material 60. The presence of the pressing plate 23 can seal the molding cavity 24 so that the material 60 is tightly pressed in the molding cavity 24, reducing the risk of displacement of the material 60 and making the position of the material 60 in the molding cavity 24 stable, thereby ensuring the molding quality of the product.

[0033] In addition, the uniform pressure provided by the pressing plate 23 can also enable the material 60 to be fully compacted under the action of the pressing mechanism, thereby improving the density and strength of the formed product.

[0034] Furthermore, both ends of the pressing plate 23 and the partition plate 22 are spaced apart from the side walls of the molding cavity 24 .

[0035] Specifically, during the processing of the material 60, due to temperature changes, thermal expansion and contraction will occur. If there is no gap between the pressing plate 23 and the inner wall of the molding cavity 24, the pressing plate 23 may be stuck in the molding die 20, making it difficult to remove or causing damage to the molding die 20. Therefore, in this embodiment, the pressing plate 23 and the partition 22 are spaced apart from the side wall of the molding cavity 24. The existence of the gap allows the pressing plate 23 and the partition 22 to have a certain amount of movement space when they are under pressure, thereby avoiding close fit with the inner wall of the molding cavity 24, which makes demolding difficult or causes mold jamming.

[0036] Furthermore, the pressing plate 23 is made of PP material. Since PP material has a high thermal deformation temperature and thermal stability, it can maintain stable performance in the high temperature environment of the pressing mechanism and will not deform or melt due to high temperature, thereby ensuring the stability and reliability of the pressing plate 23 during the hot pressing forming process of the material 60.

[0037] Furthermore, at least two partitions 22 are made of insulating material.

[0038] Specifically, the pressing mechanism in this embodiment uses a high-frequency press. In the working environment of the high-frequency press, the current may pass through the partition 22 or the material 60 to produce unnecessary thermal effects, or even cause a short circuit, causing damage to the equipment and the material 60. Therefore, the two partitions 22 are made of insulating materials. Since the insulating material has an extremely high resistivity, it can effectively isolate the current and prevent the current from leaking inside the forming mold 20 or between the materials 60, thereby avoiding short circuits and other phenomena and reducing the risk of high-frequency current causing damage to the material 60 and the forming mold 20.

[0039] Preferably, the partition 22 in this embodiment can be made of insulating materials such as electrical laminated wood or synthetic resin.

[0040] Furthermore, the material pressing driving component 31 includes a plurality of hydraulic driving components, and the plurality of hydraulic driving components are respectively connected to the material pressing seat 30 .

[0041] Specifically, multiple hydraulic drive components can act simultaneously, so that when the pressing seat 30 moves close to the molding cavity 24, the pressure in various areas of the molding cavity 24 is evenly distributed to achieve a better molding effect. In addition, compared with electric or pneumatic drive systems, the failure rate of hydraulic drive itself is lower, which helps to reduce the downtime and maintenance costs of the pressing process.

[0042] Furthermore, a pressing station and a conveying mechanism are provided on the workbench 10. The pressing mechanism is provided above the pressing station. The conveying mechanism is used to convey the forming mold 20 to the pressing station, so that the forming mold 20 can be automatically conveyed to the pressing station or moved out of the pressing station through the conveying mechanism, which is more automated.

[0043] Specifically, the conveying mechanism includes a conveying track, a driving motor 40, a transmission wheel, a driven wheel 52 and a conveyor belt. The conveying track extends along the length direction of the workbench 10. During assembly, the transmission wheel and the driven wheel 52 are rotatably installed at both ends of the conveying track. One end of the conveyor belt is wound around the transmission wheel, and the other end of the conveyor belt passes through the conveying track and extends around the driven wheel 52. Then the transmission wheel is connected to the driving motor 40 to drive the transmission wheel to rotate through the driving motor 40. In this way, when the transmission wheel rotates, the conveyor belt and the driven wheel 52 can rotate accordingly. After the forming mold 20 is installed on the conveyor belt, the conveyor belt can guide the forming mold 20 to move back and forth along the length direction of the workbench 10 during the movement, so that the forming mold 20 is transported to the pressing station, or moved out of the pressing station after the pressing is completed, making the entire structure more automated.

[0044] It should be noted that the conveyor belt can be a rack synchronous belt, a wire synchronous belt or a chain structure.

[0045] Preferably, the conveyor belt in this embodiment is a chain.

[0046] More specifically, a conveyor plate is provided on the conveyor belt, which is used to convey the forming mold 20, so as to provide stable support for the forming mold 20 and prevent the forming mold 20 from sliding or tilting due to bumps or vibrations during the conveying process, so that the forming mold 20 can be smoothly conveyed to the designated position.

[0047] The technical means disclosed in the present invention are not limited to those disclosed in the above-mentioned embodiments, but also include technical solutions composed of any combination of the above-mentioned technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and such improvements and modifications are also considered to be within the scope of protection of the present invention.
