Compared with the screw locking method, the design of the elastic latch 83 makes the replacement of the mold more convenient and quick, and the positioning support is stable, so that it can adapt to molds of various specifications, and it only needs to adjust the tightness of the elastic latch according to the size of the mold.

[0102] The general working process of the utility model is described in detail below:

[0103] During operation, the mold installation frame has been preset on the material transfer plate, and the mounting portion 82 of the mold installation frame 80 is used to cooperate with the mounting groove 90 of the material transfer plate 32 for positioning; moreover, the mold has been preset in the mold installation frame, and the mold is in an open state, and the foaming material is first installed in the foaming cavity of the lower mold;

[0104] Next, the first driving device transfers the material transfer plate to the transfer channel; the transport frame moves toward the transfer channel under the drive of the fourth driving device 716 to move the mold installation frame (together with the mold) on the material transfer plate in the transfer channel out of the transfer channel. At this time, the mold installation frame (together with the mold) is located on the transport frame, and the mold installation frame is positioned by the positioning portion 81 and the positioning groove 718.

[0105] Next, the gear driving device 7243 drives the moving plate 7247 to move along the third toothed belt 7231, so as to link the pulley assembly 722 to move upward along the slide bar assembly 721, thereby driving the moving frame 711 to move to the rear of the heating station 50. Then, the fourth driving device 716 drives the transport frame to move toward the heating station 50, so as to transfer the mold installation frame (together with the mold) into the heating station. At this time, the mounting portion 82 of the mold installation frame is positioned in cooperation with the mounting groove 90 of the upper fixed frame 51, and then the heating treatment is performed.

[0106] After the heating treatment is completed, the fourth driving device 716 drives the transport frame to move toward the heating station 50, takes out the mold installation frame and cooperates with the lifting mechanism to transport the mold installation frame to the rear of the cooling station; then the fourth driving device 716 drives the transport frame to move toward the cooling station to transfer the mold installation frame (together with the mold) after the heating treatment is completed to the cooling station. At this time, the mounting portion 82 of the mold installation frame is positioned in cooperation with the mounting groove 90 of the lower fixed frame, and then the cooling treatment is performed; at this time, the transport mechanism withdraws from the heating station;

[0107] After cooling, the mold installation frame returns to the transfer station and is transported to the transfer channel under the cooperation of the handling mechanism and the lifting mechanism. At this time, the material transfer plate is waiting in the transfer channel, and the material transfer plate moves the mold installation frame after cooling to the loading and unloading station.

[0108] The design focus of the utility model is that it mainly separates the heating station and the cooling station through the design of the transfer channel to prevent the residual temperature of the heating plate from affecting the cooling rate of the cooling plate; finally, through the coordination between the loading and unloading stations, the transfer station, the heating station and the cooling station, automatic transportation, heating and cooling of the processed products are formed, and the structural design is simple and the processing efficiency is high.

[0109] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
