HC series plastic injection molding machine has moving platen featuring box type bridge structure and full-connected rear high-rigidity mold platen. Through finite element analysis, it can prevent deforming of mold platen, resist against fatigue, have high repetition accuracy, distribute mold closing force uniformly, greatly increase mold's service life and reduce the molded parts cost.
Clamping unit: 1. Internally-rolled 5-point double toggle mold clamp structure, greatly increases rigidity and precision of the mold clamp unit. 2. With box type bridge structure, moving platen, and high rigidity continuous rear platen reinforced through finite-element analysis, we guarantee that the mold platens are not deformable and are durable. 3. The tie rods are made of high quality structural alloy steel plated with hard chromium, with high mechanical strength and fatigue strength. 4. Provided with low-pressure mold protection device. 5. Multi stages controlling of mold clamp pressure, speed and position. 6. Mold thickness adjusted through ring gear driven by hydraulic oil motor. 7. Several hydraulic ejection modes.
Injection unit: 1. Use of double guide posts and dual-cylinder balance injection device, guarantees that balanced and uniform forces are applied on the screw during injection and moving forward. 2. High quality alloy screw nitride or with chromium plating, and nitride barrels, are protected against corrosion and fatigue, which greatly increase their service life. 3. With fine adjustment of nozzle centering. 4. Screw preplasticizing driven by high torque hydraulic motor device. 5. Multiple injection speed, pressure and position settings. 6. Special screws and barrels are provided according to different properties of engineering plastics to ensure the molding quality of finished products.
Lubricant unit: 1. With use of volumetric electrical lubricator, automatic centralized lubrication and uniform oil distribution in the pipeline, the machines have high lubrication efficiency and long toggle life. Hydraulic unit: 1. Well-known oil pump and control valves in the world are used, to execute accurate controlling over the force, speed and direction of hydraulic mechanism and ensure the accuracy, reliability, stability and durability of the machine. 2. Control system of the constant displacement pump ensures steady outputs and high response. 3. Main hydraulic elements and seals are international well-known brands. 4. The pipelines are arranged more reasonably and better, and thus ensure easy maintenance.
