250 T Small Plastic Injection Molding Machine Tie Bar Structure Design

250 T Small Injection Molding With Ultra-High Rigidity Square Plate and Tie Bar Structure Design

OUCO is a factory focusing on the research and development of small  injection molding machines. The injection molding machines we produce are efficient, energy-saving and intelligent equipment,which is mainly composed of the following four parts

Hydraulic System

The system pressure is upgraded from 16 MPa to 17.5 MPa, and the hydraulic system flow is upgraded and upgraded with low inertia and high response servo system. With the characteristics of large pipe diameter, short pipe length, fast response, low noise and strong power, the injection speed is fully improved.

Clamping Unit

1. Optimized design of five-point elbow clamping structure, with good central clamping effect, large opening stroke, low contact stress of shaft pin, more suitable for deep cavity product forming. This machine has a shorter drying cycle.

2. Ultra-high rigidity square plate + tie bar structure design, in line with international mold design standards, improve mold adaptability, reduce the main stress, more uniform plate force, extend the life of the tie bar, and more effectively fit and protect the mold.

3. Optimized switch structure improves the service life of the machine and reduces the maintenance cost. The ejection part is equipped with forced retraction device as standard, with longer ejection stroke and freely adjustable ejection position.

4. Side hanging new mechanical safety structure, more convenient to operate and safer to use.

Injection device

1. The injection base is made of integral casting. New injection structure has lower oil return resistance. Standard configuration of bushing guide and electronic back pressure with closed-loop function reduces friction for smoother machine operation and improved repeatable injection accuracy of products.

2. Optimized screw and barrel design with standard plated and bimetallic screw and increased barrel wall thickness. The screw drive adopts spline connection, which makes the screw rotate with more even force. It improves the plasticizing ability and injection precision.

3. Non-welded pipe effectively avoids oil leakage; self-sealing suction filter is more convenient for maintenance, and high-precision bypass filter improves oil cleanliness.

4. Automatic thin oil lubrication system design ensures full lubrication coverage and smoother. Built-in lubrication pump design, saving rack space and improving transportation safety.

Electrical control system

1. New generation of servo power system is more energy-saving and environmental protection; increased power of oil pump motor drive system, shortening the product molding cycle and widening the molding process.

2. Advanced electronic control system, larger operation panel, more stable and reliable work, higher operation precision and safety protection level.

The function of intelligent Internet management system follows the trend of Industry 4.0 and opens a new era of intelligent factory

3. The rotary switch supports opening the door and cutting off the power, and the new safety upgrade meets CE standards.
