Thus, after the foam is taken out from the mold structure 3 by the operator at the taking-out station, the mold frame 5 is continuously moved to the position of the third guide rail 73, and then the second sliding portion 521 of the second adjusting frame 52 slides on the third guide rail 73 as the mold frame 5 is continuously moved, the third guide rail 73 guides the second adjusting frame 52 to rotate from the inclined state to the parallel state relative to the horizontal plane, so that the second adjusting frame 52 with the second mold 32 is adjusted to the horizontal state, so that the process that the second mold 32 can be effectively operated when the second mold 32 is required to be in the horizontal state is performed (for example, a material injection station for injecting the foam material into the mold is arranged at the downstream position of the third guide rail 73, and the second mold 32 is adjusted to the horizontal state so that the second mold 32 can contain a sufficient amount of the foam material, and then the foam material is injected into the second mold 32), the second adjusting frame 52 does not need to be driven by manpower to rotate to the horizontal state, and the production efficiency is improved. In detail, in the present embodiment, an injection station for injecting the foaming material into the mold is disposed at a downstream position of the third guide rail 73; in other embodiments, the specific type of process station disposed downstream of the third guide track 73 may also be suitably adjusted according to the actual situation. In the present embodiment, the first sliding member 512 and the second sliding member 521 are both roller members.

In this embodiment, the base 53 is further provided with a support portion 532 for supporting the second adjustment frame 52, so that the second adjustment frame 52 can abut against the support portion 532 when not driven by external force. In this way, after the driving force applied to the second adjusting bracket 52 is cancelled, the second adjusting bracket 52 abuts against the support part 532 under the action of self gravity to keep a static state, so that the second adjusting bracket 52 is prevented from shaking back and forth to touch equipment or workers after losing the driving force, and the safety performance is improved.
