The two ends of the circulation pipe can be connected to the main pipe, and a sealing ring is provided between the circulation pipe and the main pipe.

[0004] In actual use, due to the high temperature of the hot medium inside the main pipeline and circulation pipe, the damage rate of the sealing ring is high. Therefore, in order to improve the service life of the sealing ring, it is urgent to improve the structure of the sealing ring installation location. Utility Model Content

[0005] The purpose of this application is to provide a molding machine with a pipe sealing ring protection structure for the production of polystyrene boards, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides a molding machine for producing polystyrene boards with a pipe sealing ring protection structure, which adopts the following technical solution:

[0007] A molding machine for producing polystyrene boards with a pipe sealing ring protection structure includes a mold box with a side opening. A mold cover is provided on one side of the mold box opening. The bottom end of the mold cover is hinged to the mold box. A driving mechanism for opening and closing the mold cover is provided at the bottom of the mold box. Several locking components are also connected between the mold cover and the mold box. Flow channels are respectively provided inside the mold box and the mold cover. A main pipe connected to the internal flow channels is provided on the mold box. A circulation pipe connected to the internal flow channels is provided on the mold cover. Both ends of the circulation pipe can be connected to the main pipe. A connecting pipe connected to the end of the circulation pipe is provided on the main pipe. An annular boss is fixed on the surface of the connecting pipe. A sealing ring is installed on the end face of the annular boss. An annular groove is formed inside the annular boss. The annular boss is fixed on the surface of the connecting pipe. A cooling groove is formed between the annular groove and the connecting pipe. A heat insulation layer is provided on the surface of the connecting pipe corresponding to the position of the annular groove. An inlet and an outlet are provided on the annular boss.

[0008] Preferably, the annular boss comprises an integrally formed small cylindrical segment and a large cylindrical segment, the annular groove is formed in the small cylindrical segment, and sealing rings are installed on the end faces of both the small cylindrical segment and the large cylindrical segment.

[0009] The end faces of the small cylindrical segment and the large cylindrical segment are evenly provided with multiple through holes, and the circumference of the small cylindrical segment and the large cylindrical segment is provided with an annular groove. The annular groove is connected to the through holes. The sealing ring includes an integrally formed ring body and a positioning post. The positioning post passes through the through hole.

[0010] An annular stop portion is provided on the inner wall of the port of the circulation pipe, and the annular stop portion can abut against the end face of the small cylindrical segment.

[0011] By adopting the above technical solution, after the mold cover and mold box are closed, the end face of the circulation pipe abuts against the sealing ring of the large cylindrical section, and the annular stop part inside the circulation pipe abuts against the sealing ring of the small cylindrical section, thereby realizing the sealed connection between the main pipe and the circulation pipe. The setting of two seals can improve the sealing effect.

[0012] Preferably, in order to improve the strength of the positioning post, a number of metal wires are provided inside the positioning post.

[0013] In summary, this application includes at least one of the following beneficial technical effects: the molding machine for producing polystyrene board with a pipe sealing ring protection structure is equipped with a connecting pipe, a fixed annular boss on the surface of the connecting pipe, and a sealing ring installed on the annular boss. A cooling tank is provided inside the annular boss. After the mold is closed, a cooling medium is introduced into the cooling tank through the liquid inlet. The cooling medium can remove the heat on the annular boss, so that the annular boss as a whole is in a relatively low temperature state, thereby avoiding the sealing ring being in a high temperature environment for a long time, and thus improving the service life of the sealing ring.

Detailed Implementation

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0019] This application discloses a molding machine with a pipe sealing ring protection structure for polystyrene board production, referring to... Figure 1-3 The system includes a mold box 1 with a side opening, a mold cover 2 on one side of the opening, the bottom of the mold cover 2 being hinged to the mold box 1, a drive mechanism for opening and closing the mold cover 2 at the bottom of the mold box 1, and several locking components connecting the mold cover 2 and the mold box 1. Flow channels are provided inside both the mold box 1 and the mold cover 2. A main pipe 11 connected to the internal flow channels is provided on the mold box 1, and a circulation pipe 21 connected to the internal flow channels is provided on the mold cover 2. Both ends of the circulation pipe 21 can be connected to the main pipe 11. On the main pipe 11, a connecting pipe 3 is provided to connect with the end of the circulation pipe 21. An annular boss 31 is fixed on the surface of the connecting pipe 3. A sealing ring 4 is installed on the end face of the annular boss 31. An annular groove 313 is opened inside the annular boss 31. The annular boss 31 is fixed on the surface of the connecting pipe 3. A cooling groove 5 is formed between the annular groove 313 and the connecting pipe 3. An insulation layer 6 is provided on the surface of the connecting pipe 3 at the position corresponding to the annular groove 313. An inlet and an outlet are provided on the annular boss 31.

[0020] Reference Figure 2-3 The annular boss 31 includes an integrally formed small cylindrical section 311 and a large cylindrical section 312. An annular groove 313 is formed in the small cylindrical section 311. Sealing rings 4 are installed on the end faces of the small cylindrical section 311 and the large cylindrical section 312. An annular stop part 211 is provided on the inner wall of the port of the circulation pipe 21. The annular stop part 211 can abut against the end face of the small cylindrical section 311.

[0021] Reference Figure 2 Multiple through holes 3111 are evenly provided on the end faces of the small cylindrical section 311 and the large cylindrical section 312. Annular grooves 3112 are provided on the circumference of the small cylindrical section 311 and the large cylindrical section 312. The annular grooves 3112 are connected to the through holes 3111. The sealing ring 4 includes an integrally formed ring body and a positioning post. The positioning post passes through the through hole 3111. A clamp 7 is also matched and provided in the annular groove 3112. The clamp 7 is used to press the positioning post into the annular groove 3112. The clamp 7 is generally an earless, stepless clamp. In order to improve the strength of the positioning post, several metal wires are provided inside the positioning post.

[0022] By using clamp 7 to fix the sealing ring 4 on the annular boss 31, the sealing ring 4 can be limited to prevent it from falling off. On the other hand, the clamp 7 makes it easy to disassemble and replace the sealing ring 4, making it more convenient to use.

[0023] The implementation principle of a molding machine with a pipe sealing ring protection structure for polystyrene board production according to an embodiment of this application is as follows:

[0024] After the mold cover 2 and the mold box 1 are closed, the end face of the circulation pipe 21 abuts against the sealing ring 4 of the large cylindrical section 312, and the annular stop part 211 inside the circulation pipe 21 abuts against the sealing ring 4 of the small cylindrical section 311, thereby realizing the sealed connection between the main pipe 11 and the circulation pipe 21. The setting of two seals can improve the sealing effect.

[0025] After the mold is closed, cooling medium (usually water) is introduced into the cooling tank 5 through the liquid inlet. The cooling medium can carry away the heat on the annular boss 31, so that the annular boss 31 is in a relatively low temperature state, thereby preventing the sealing ring 4 from being in a high temperature environment for a long time, and thus improving the service life of the sealing ring 4.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
