The implementation of multi station operation in hot press machines mainly relies on three core mechanisms: structural modular design, automated material flow, and independent station control. Combined with specific cases, the following technical paths can be summarized:

1、 Modular structure design: space reuse improves efficiency

Multi station hot press machines usually adopt a structure of multiple independent hydraulic mechanisms and shared frames. For example, a multi station hot press machine is used for processing insulation boards, with two hydraulic mechanisms arranged side by side on the base. Each mechanism includes an independent upper pressure plate, lower pressure plate, column, and hydraulic cylinder, forming two hot press stations. Two sets of workstations share a steam heating system and a cooling water tank, which are connected to the inlet and outlet of each pressure plate through air and water pipes respectively, achieving independent temperature control. This design allows the equipment to simultaneously process products of different specifications or batches, such as hot pressing thin plates at one station and thick plates at another station, without the need to stop and replace molds.

2、 Automated material flow: reducing manual intervention

Some multi station hot press machines achieve full process automation through integrated feeding, hot pressing, and discharging modules. For example, a multi station automatic hot press adopts a "zigzag" layout:

Feeding module: Push the material tray to the feeding end of the integrated hot pressing module through the feeding slide table, cylinder, and push rod;

Hot pressing module: After the tray enters the vacuum chamber, the closed door automatically seals, and the hot pressing lever drives the pressing shaft component to complete the hot pressing;

Discharge module: The discharge mechanical arm pull rod pulls the material tray out of the cavity and into the discharge chute.

The entire process is controlled by PLC, and the circulation time error of the material tray between workstations is ≤ 0.5 seconds, which is more than three times more efficient than a single workstation.

3、 Independent workstation control: dynamic parameter adaptation

Each station of the multi station hot press can independently set temperature, pressure, and time parameters. For example, a rotating multi station high-frequency hot press machine is equipped with three rotating hot press plates on the turntable, each plate corresponding to a station:

Workstation 1: Fixing materials with fixed grooves and limit clamps, suitable for heat sealing of fine electronic components;

Workstation 2: Adjust the pressure of the limit spring to adapt to different thicknesses of plates;

Workstation 3: Turn off the heating function and only use it for pressure maintaining cooling.

Operators can monitor the status of each workstation in real-time through the human-machine interface and dynamically adjust parameters according to product requirements to avoid an increase in defect rates due to parameter conflicts.
