20MPa 300 Ton Rubber Gasket Seal Injection Machine Rubber Mudflap Molding

Vertical 300 Ton Rubber Gasket Seal Injection Machine Rubber Mudflap Molding


Common Problems for FIFO Rubber Injection Molding Machine:

  1. In order to solve the shortcomings of the above two injection machines, people combine these two injection machines to make up for each other, which is the screw that is currently used more.
  2. Plunger injection molding machine. The injection part of this machine is mainly composed of a screw plasticizing system and a plunger injection system. The injection molding process is as follows:
  3. The cold compound is fed into the screw plasticizing system. After the rubber is plasticized by the screw, it is squeezed into the plunger injection system, and finally the rubber is injected into the cavity by the plunger. for
  4. In order to make the rubber flow in a certain order, a check valve is installed at the end of the screw extruder, and the plastic material is plasticized and then enters the injection system through the check valve.
  5. The plunger is pushed up, and the rubber does not go out of the nozzle because the nozzle passage is narrow and the resistance is large. When the plunger injects the compound from the nozzle into the cavity at a high pressure,
  6. Because of the action of the check valve, the rubber does not flow back into the injection machine. Since this injection molding method combines a plunger type injection machine and a screw type injection machine
  7. The advantage is that it can produce large, high quality rubber products.
  8. Plasticizing systems and injection system installation methods, sometimes there may be some defects, because the glue first injected into the injection chamber is finally injected into the cavity,
  9. This may cause the rubber which is in contact with the end face of the plunger to stay for too long to cause vulcanization, which may cause problems such as waste. Large devices are more prone to this kind of
  10. Happening. A first-in, first-out injection machine can solve this problem.
  11. Although the rubber injection machine is also divided into two parts: screw plasticizing and plunger injection, the two parts are installed in a straight line. At the beginning of the work,
  12. The plunger is in the front position, and when the plasticized rubber enters the injection chamber from the front end of the screw through the plunger, the plunger starts to retreat under the pressure of the rubber material.
  13. Until the injection chamber is filled with the required injection volume, the plunger stops moving backward. Then the power part drives the plunger to move forward, high pressure injection, and another
  14. In addition, when the rubber material passes through a spherical splitting shuttle before entering the mold, it is further plasticized, and the temperature of the rubber compound is more uniform.

Rubber Injection Machine Characteristics:

  1. This machine is composed of four parts: body part, heating plate part, hydraulic power part and electric control part. The hydraulic cylinder is made of ductile iron and the plunger is cold.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 other parts are excellent.Made of carbon steel or alloy steel.
  2. The main seal of the cylinder adopts yx type seal, which is reliable in sealing and long in service life.
  3. Electric heating is controlled by electronic temperature controller, which has the advantages of high temperature control precision, intuitive display and convenient adjustment.
  4. This machine uses the moving template to move the moving template out of the machine through the guide rail, which greatly facilitates the user's demand 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 electric 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 rapid rise of the plunger, slow clamping, automatic injection, and automatic pressure retention, pressure, drop, push and pull, ejection and other actions.
