Rubber Injection Machine Catagories:

There are many types of rubber injection molding machines. So far, rubber injection molding has gone through three stages: plunger injection, screw reciprocating injection and screw Rod-plunger injection.Plunger injection molding machine

• The earliest rubber injection molding machine used a plunger injection molding machine. The injection molding method is: after feeding the rubber material from the feeding port into the barrel, the barrel is outsideThe heater in the section heats and plasticizes the rubber material, so that the rubber material reaches a temperature that is easy to inject without scorching. Finally, the plunger will make the plasticized compound highPress into the mold. In fact, the barrel of this injection method mainly plays the role of injection, supplemented by the role of heating and plasticizing. Because rubber is a bad conductor of heat,The thermal efficiency is low. If the rubber compound is heated only by heat conduction, the temperature of the rubber compound rises too slowly and the plasticization is uneven. Therefore, the rubber compound needs to be smelted first. Hot smelting in the machine, and then feeding into the injection machine after smelting to a certain degree. Therefore, although this injection molding method has a simple structure and low cost, it requires. It is necessary to configure hot mixers and rubber mixing workers, which increases equipment costs and labor intensity of workers. The most important thing is that this injection molding method has low production efficiency and plastic. Non-uniform, which affects the quality of products.

The rubber injection machine has the following characteristics:

1. This machine is composed of four parts: fuselage parts, heating plate parts, hydraulic power parts and electrical control parts. The hydraulic cylinder is made of ductile iron, the plunger is cold. It is made of hard cast iron to improve its compressive strength and wear resistance, and reduce the structure of the whole machine. The platform and upper beam are welded with high-quality carbon steel, and the rest of the parts are made of excellent. Made of quality carbon steel or alloy steel.
2. The main seal of the oil cylinder adopts yx type seal, which has reliable sealing and long service life.
3. Electric heating is controlled by electronic temperature controller, which has the advantages of high temperature control accuracy, intuitive display and convenient adjustment.
4. The machine adopts the moving template to move the moving template and the mold out of the machine through the guide rail, which greatly facilitates the user's needs for various products.
5. Hydraulic control system. The rubber injection machine is equipped with two CBN-F310 hydraulic pumps, which are directly driven by the motor, and supply oil to the hydraulic cylinder through each control valve;
6. The control valve constitutes the entire control system. The system works in conjunction with the electrical control system to control the plunger's rapid rise, slow mold clamping, automatic injection, and automatic pressure retention, Compensation, descent, push-pull, ejection and other actions.
