A linkage demolding stop structure is arranged on one side of the heat insulation plate body. The linkage demolding stop structure includes a demolding outer auxiliary part connection channel arranged at the lower end of the hot plate body, an inserted flow-stop component arranged in a shape matching the intercepting channel of the demolding outer auxiliary part connection channel, a stop part connection hole arranged in the upper part of the hot plate body, a linkage pin component arranged in the stop part connection hole, and an inner locking part arranged in the upper part of the hot plate body.

[0005] The inserted flow-stop component includes a linkage demolding pin shaft body and a connection handle arranged at the outer end of the linkage demolding pin shaft body. The connection handle is connected to the whole-machine demolding control component.

[0007] The inner locking part includes an inner locking pin part and a locking inner sleeve body.

[0008] The beneficial effect of the utility model: This structure effectively ensures that the heat insulation plate body, the injection plate body, the demolding plate, and the film-changing drive cylinder group are quickly demolded under the action of the whole-machine demolding control component during the whole-machine demolding process. And an inserted flow-stop component is arranged on the heat insulation plate body to ensure that the upper mold body will not fall off, effectively ensuring the service life of the mold and improving the injection molding efficiency of the mold.
