[0043] The working principle and use process of the present invention are as follows: before use, water is injected into the liquid storage metal box 22 through the water inlet metal pipe 24, so that the liquid level in the liquid storage metal box 22 is slightly below the cooling metal plate 233 (for example, 1-3 cm apart). When in use, the second position changing member 311 is controlled to extend to move the fourth bearing metal plate 323 downward. The fourth bearing metal plate 323 after moving downward abuts against the metal lower mold 234, thereby achieving the mold closing of the metal lower mold 234 and the fourth bearing metal plate 323. Then, the injection machine is controlled to inject The material through hole 332 is used to inject material into the interior of the metal lower mold 234, thereby realizing the processing of the workpiece. In the process of cooling and shaping the workpiece, the second position changing member 311 is further controlled to extend so that the fourth bearing metal plate 323 drives the second bearing metal plate 232 to move downward, so that the cooling metal plate 233 is inserted into the water (the bottom of the metal lower mold 234 can also be inserted into the water), thereby realizing water cooling of the workpiece, so as to realize rapid cooling and shaping of the workpiece. At this time, the elastic pressure relief cover 25 expands accordingly to realize pressure relief;

[0044] Then, the second position changing member 311 is controlled to contract to make the metal upper mold 322 move upward. At this time, due to the limiting effect of the anti-slip metal rod 330 on the workpiece, the workpiece is separated from the metal lower mold 234 and moves up with the metal upper mold 322. As the metal upper mold 322 continues to move upward, the first position changing plate 312 cooperates with the second position changing plate 327 to press the deformable transmission rope 328, so that the anti-slip metal rod 330 shrinks to the inside of the metal upper mold 322 to release the limiting fixation of the workpiece. Then, the third position changing member 324 is controlled to extend and the second position changing member 311 is controlled to contract synchronously to achieve the relative stillness of the first position changing plate 312 and the second position changing plate 327, so that the metal upper mold 323 gradually moves upward relative to the fourth supporting metal plate 322, so that the workpiece stranded on the metal upper mold 323 is pushed down by the fourth supporting metal plate 322, so as to achieve rapid and reliable demoulding of the workpiece.

[0045] Therefore, through the linkage of multiple structures, the workpiece can be demoulded quickly and reliably, thereby eliminating the need for users to frequently demould manually, thereby improving the user experience of the plastic mold. Secondly, the present invention has a cooling function, which can effectively shorten the time consumed in the workpiece molding process, thereby improving the processing efficiency of the plastic mold. In addition, the present invention has a simple structure, is easy to use, and is worthy of promotion and use.
