Description

Technical Field

[0001] The utility model relates to the technical field of acrylic plate production, in particular to an acrylic plate shaping and pressing device. Background Art

[0002] Acrylic plate, scientifically named polymethyl methacrylate, is a thermoplastic plastic made through the polymerization reaction of monomer methyl methacrylate. It plays an important role in modern society with its unique properties and wide application fields.

[0003] Currently, in the production and processing of acrylic plates, a hot press is mostly used to make the acrylic plate reach the required shape and size, while ensuring its stability and durability. However, in the actual use of traditional acrylic plate hot presses, since natural heat dissipation is mostly used after hot pressing, if the temperature control is not in place, it will cause the plate to stick to the pressing plate, resulting in plate deformation, or the plate falling after the upper pressing plate rises. Therefore, there is an urgent need for an acrylic plate shaping and pressing device. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to propose an acrylic plate shaping and pressing device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] An acrylic plate shaping and pressing device includes a hot press body. A hot pressing cavity is provided in the middle of the hot press body. An upper pressing plate and a lower pressing plate are respectively installed in the upper and lower parts of the hot pressing cavity. Multiple seamless holes are provided on the pressing surfaces of the upper pressing plate and the lower pressing plate. A top column is installed in the seamless holes in a limited way. Air channels are provided on both sides of the top column. A nozzle is provided above the air channel, and the nozzle is connected to a trachea.

[0007] In addition, a preferred structure is that an installation groove is provided on one side of the inner wall of the hot pressing cavity, and a trachea is embedded and installed in the installation groove. One end of the trachea is connected to the lower pressing plate, and the other end is connected to the upper pressing plate.

[0008] In addition, a preferred structure is that telescopic grooves are provided on both sides of the inner wall of the seamless hole. A spring is installed at the bottom of the telescopic groove. The other end of the spring is connected to a wedge block. The wedge block is installed on both sides of the outer wall of the top column, and the wedge block is installed in the telescopic groove in a limited sliding way.

[0009] In addition, a preferred structure is that a heat-conducting pressing piece is installed on the bottom wall of the top column, and the heat-conducting pressing piece is flush with the pressing surface of the upper pressing plate in the natural state.

[0010] In addition, a preferred structure is that the air channel and the inner wall of the seamless hole form a sealed cavity, and a nozzle is correspondingly provided at the top of the cavity.

[0011] In addition, a preferred structure is that the pressing surfaces of the upper pressing plate and the lower pressing plate are correspondingly provided with ejector pins.

[0012] The beneficial effects of the present utility model are as follows:

[0013] In the present utility model, a plurality of ejector pins are respectively arranged on the pressing surfaces of the upper and lower pressing plates. After the hot pressing operation is completed, gas is sent into the trachea through an external air pump, and the air channels on both sides of the ejector pins are pressurized through the air nozzles, so that the ejector pins press against the surface of the workpiece, and at the same time, gas is ejected to cool and separate between the workpiece and the pressing surface, effectively improving the cooling efficiency of the workpiece, and avoiding the situations of workpiece adhesion and uneven cooling, thereby improving the processing quality.

Detailed Embodiments

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0020] Refer to Figures 1-4 , an acrylic plate shaping and pressing device, including a hot press machine body 1, a hot pressing cavity 2 is arranged in the middle of the hot press machine body 1, an upper pressing plate 3 and a lower pressing plate 4 are respectively installed on the upper and lower parts of the hot pressing cavity 2, wherein a plurality of seamless holes 7 are opened on the pressing surfaces of the upper pressing plate 3 and the lower pressing plate 4, an ejector pin 8 is installed in the seamless hole 7 in a limited way, air channels 82 are opened on both sides of the ejector pin 8, an air nozzle 11 is arranged above the air channel 82, and the air nozzle 11 is connected to the trachea 6.

[0021] Further, an installation groove 5 is formed on one side of the inner wall of the hot pressing cavity 2. An air pipe 6 is embedded and installed in the installation groove 5. One end of the air pipe 6 is connected to the lower pressing plate 4, and the other end is connected to the upper pressing plate 3, thereby realizing the normal operation of the corresponding nozzles in the upper and lower pressing plates.

[0022] Further, telescopic grooves 9 are formed on both sides of the inner wall of the seamless hole 7. A spring 10 is installed at the bottom of the telescopic groove 9. The other end of the spring 10 is connected to a wedge block 83. The wedge block 83 is installed on both sides of the outer wall of the top column 8, and the wedge block 83 is installed in the telescopic groove 9 in a limited sliding manner.

[0023] Further, a heat conducting pressing piece 81 is installed on the bottom wall of the top column 8. The heat conducting pressing piece 81 is flush with the pressing surface of the upper pressing plate 3 in the natural state, ensuring the normal operation of the upper and lower pressing plates.

[0024] Further, an airtight cavity is formed between the inner wall of the air passage 82 and the seamless hole 7. A gas nozzle 11 is correspondingly arranged at the top of the cavity. The gas nozzle 11 is connected to an external air pump through the air pipe 82.

[0025] Further, top columns 8 are correspondingly arranged on the pressing surfaces of the upper pressing plate 3 and the lower pressing plate 4, thereby ensuring the uniformity of the pressing force applied to the workpiece.

[0026] In this embodiment, the corresponding acrylic plate workpiece is placed in the hot pressing cavity 2 in the heating machine body 1. By starting the heating machine body 1, the upper pressing plate 3 and the lower pressing plate 4 are heated and pressed against each other. After the pressing is completed, the external air pump sends gas into the seamless holes 7 in the upper and lower pressing plates 4 through the air pipe 6. Corresponding top columns 8 and gas nozzle 11 assemblies are arranged in the seamless holes 7. The gas nozzle 11 sends the gas into the air passages 82 formed on both sides of the top column 8. At this time, under the gas pressure, the ejected gas pushes the top column 8 outwards through the heat conducting pressing piece 81 at the bottom of the top column 8 and applies a uniform force to the surface of the workpiece. At the same time, during the ejection process, when the air passage 82 is exposed from the seamless hole 7, the gas flows outwards and flows into the gap between the workpiece and the pressing surface, thereby improving the cooling efficiency of the workpiece surface and increasing its separation efficiency.

[0027] Among them, during the actual use process, the top column 8 presses down to compress the spring 10. After the gas nozzle 11 stops discharging gas, the spring 10 retracts and drives the top column 8 to reset, so that the heat conducting pressing piece 81 is flush with the pressing surface again.

[0028] In the present utility model, a plurality of top columns 8 are respectively arranged on the pressing surfaces of the upper and lower pressing plates. After the hot pressing operation is completed, the external air pump sends gas into the air pipe 6, and the gas nozzle 11 applies pressure to the air passages 82 on both sides of the top column 8, so that the top column 8 presses against the surface of the workpiece, and at the same time, the ejected gas cools and separates the workpiece and the pressing surface, effectively improving the cooling efficiency of the workpiece and avoiding the situations of workpiece adhesion and uneven cooling, thereby improving the processing quality.

[0029] As described above, it is only the preferred specific embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
