DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] A bottom groove 15 is provided near the center of the bottom of the lower mold 6, and a heat conduction cavity 26 is provided near the inner top of the bottom groove 15. A heat conduction plate 27 is fixed in the heat conduction cavity 26 by tightening bolts 28. A heat pipe 29 is pre-embedded in the heat conduction plate 27, and a heat dissipation fin 30 is welded to the outside of the heat pipe 29.

[0025] When in use, the servo electric cylinder 8 drives the pressing plate 20 to move into the molding cavity 25 when working. The molding cavity 25 can be used to foam the polyphenylene ether material. The heat generated by the foaming of the molding cavity 25 will be transferred to the heat conducting plate 27 through the bottom, and then the heat exchange of the heat conducting plate 27 will be realized through the heat pipe 29 and the heat dissipation fins 30, so that the mold has a rapid heat dissipation structure, which can facilitate the timely dissipation of the heat generated during foaming, and the efficiency during foaming production is higher.

[0026] For example, Figure 1As shown, the utility model also includes that connecting blocks 2 are provided at both ends of the base 1 near the bottom, and a mounting hole 3 is formed through the bottom of the connecting block 2.

[0027] When in use, the connecting block 2 is conveniently fixed by passing the external bolts through the mounting holes 3, thereby installing the mold.

[0028] For example, Figure 1 As shown, the utility model further includes that a reinforcing support plate 7 is connected between the vertical plates 4 near the bottom, and a supporting plate 9 is arranged between the bottom of the reinforcing support plate 7 and the base 1 .

[0029] When in use, by reinforcing the carrier plate 7 and the support plate 9, the bottom of the servo electric cylinder 8 can be provided with a reinforced structure, which is beneficial to improving the stability of the installation structure at the bottom of the servo electric cylinder 8.

[0030] For example, Figure 1 and Figure 2 As shown, the utility model also includes that guide grooves 13 are penetrated at both ends of the top of the lower mold 6, the bottom grooves 15 pass through the corresponding guide grooves 13, and vertical bearings 14 are provided at the top and bottom of the lower mold 6 near the guide grooves 13.

[0031] When in use, the vertical bearing 14 and the guide groove 13 provide limiting and guiding effects on the displacement column 12 , thereby effectively improving the stability of the upper mold 19 when it moves up and down.

[0032] For example, Figure 1 and Figure 2 As shown, the utility model also includes that extension columns 16 are provided at the top near both ends of the bottom groove 15, a first buffer pad 17 is provided at the bottom of the extension column 16 through a mounting groove, and second buffer pads 18 are provided at both ends of the top of the lower mold 6 through a fixing seat.

[0036] When the utility model is in use, the raw materials for the production of polyphenylene ether foaming are conveniently added into the multi-way valve 23 through the first feed pipe 24. When the stop valve 22 is opened, a variety of raw materials enter the molding cavity 25, and molding is performed in the stop valve 22. When the servo electric cylinder 8 is working, it can drive the three lifting plates 11 to move up and down. When the lifting plates 11 move, they can drive the displacement column 12 and the upper mold 19 to move downward. When the upper mold 19 moves downward, it drives the pressing plate 20 to move into the molding cavity 25, so that the molding cavity 25 is closed, and the molding cavity 25 can be used to perform foam molding on the polyphenylene ether material;

[0037] The heat generated by the foaming of the molding cavity 25 will be transferred to the heat conducting plate 27 through the bottom, and then the heat exchange of the heat conducting plate 27 will be realized through the heat pipe 29 and the heat dissipation fins 30, so that the mold has a rapid heat dissipation structure, which can conveniently dissipate the heat generated during foaming in time, and the efficiency during foaming production is higher.
