Core Description
A heavy-duty, two-way sliding mold hydraulic vulcanizing press designed for manufacturing large rubber products. It features a dual-layer hot plate system, high working pressure, and mold interchangeability for flexible, high-volume production.

Key Features & Specifications

1. Structural Design

   • Frame & Platens: Fabricated from Q235 steel, shot-blasted, zinc-rich primed, and stress-relieved via machining.

   • Hot Platens: Dual-sizing 45# steel plates, normalized; equipped with automated electric steam valves and bypass for precise temperature control (steam/water switching capability).

   • Platforms: Upper/lower platforms of Q235 steel, precision-welded using CO₂ shielded arc welding with alloy wire, followed by full furnace stress relieving to prevent deformation.

2. Hydraulic & Actuation

   • Cylinder Assembly: ZG270-500 cast cylinder with chilled alloy cast iron plunger.

   • Sealing System: Dual seals + integrated dust ring for extended service life.

   • Mold Movement: Front/rear sliding mold device supports hydraulic or mechanical actuation, capable of handling molds of any weight.

3. Control System

   • Automation: PLC-based full-automatic control for clamping, mold opening, exhaust setting, and manual override capability.

4. Production Advantages

   • Flexibility: Quick mold changeover for diverse rubber product lines.

   • Efficiency: Two working layers enable high throughput.

   • Precision: Camber-compensated rolls ensure uniform product thickness.

5. Safety & Reliability

   • Emergency stop system, bearing lubrication failure alarm, and robust construction for continuous industrial operation.

Applications
Ideal for vulcanizing large-scale rubber products such as seals, mats, industrial components, and customized molded rubber items.
