When the first hollow cover (32) is driven by the first driving part (34) to move to the first closing position, the bottom end opening is in airtight contact with the upper disc surface of the rotary disc (21), and the gas can be prevented from flowing between the interfaces where the first hollow cover (32) and the rotary disc (21) are in contact with each other, so that the inner space of the first hollow cover (32) in close contact with the rotary disc (21) is defined as a first working space; in contrast, when the second hollow cover (33) is driven by the second driving part (35) to move to the second closed position, the top opening is in airtight contact with the lower disk surface of the turntable (21), and the gas can be prevented from flowing between the interfaces where the second hollow cover (33) and the turntable (21) are in contact with each other, so that the inner space of the second hollow cover (33) in close contact with the turntable (21) is defined as a second working space.

Each of the second vertical mold clamping mechanisms (40) is a known technical content for providing a mold clamping force, and its specific structure is not shown, but it should be noted that, as shown in fig. 1, the number of the first vertical mold clamping mechanism (30) and the number of the second vertical mold clamping mechanism (40) are two, that is, the number of the hot zone stations and the number of the cold zone stations are two, respectively, and the remaining one station is used as a cleaning station for taking, cleaning and placing the material.
