Products Applications:

  1. Rubber injection molding machine is mainly used in the production of auto parts, industrial parts, electrical insulation parts, connector sockets, seals, cushions, shockproof covers, shoes, corks, vacuum hoses, jackets, valve pads, toys And fitness equipment, etc. With the development of the automotive industry, the quality requirements for seals, electrical connectors, shock absorbers, etc. are getting higher and higher, and the demand for rubber injection only increases by more than 12,000 times. The strong market demand is the development of rubber injection machines. Provide an opportunity.


Machine Working Thoery Introduction:

  1. The injection part of the machine is mainly composed of a screw plasticizing system and a plunger injection system. The injection molding process is as follows: first, the cold rubber material is fed into the screw plasticizing system, and the rubber material is plasticized by the screw and squeezed into the plunger. In the injection system, z is finally injected into the mold cavity by the plunger. In order to make the rubber flow in a certain order, a check valve is installed at the end of the screw extruder. After the plastic material is plasticized, it enters the injection system through the check valve and pushes the plunger up. Going out of the nozzle, because the nozzle passage is narrow, the resistance is large. When the plunger injects the compound from the nozzle into the mold cavity at a high pressure, the rubber does not flow back into the injection machine due to the action of the check valve. Since this injection molding method combines the advantages of a plunger type injection machine and a screw type injection machine, it can produce large-sized, high-quality rubber products.
  2. Plasticizing system and injection system installation method, sometimes there may be some defects, because the rubber injected into the injection chamber is finally injected into the cavity, which may cause the rubber to stay in contact with the end face of the plunger to stay too long. Vulcanization, resulting in problems such as waste. Large devices are more prone to this situation. A first-in, first-out injection machine can solve this problem.
  3. Although the FIFO 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, the plunger is at the front position, when the plasticized rubber is from the screw. At the front end, after entering the injection chamber through the plunger, the plunger starts to retreat under the action of the rubber pressure until the injection chamber is filled with the required injection amount, and the plunger stops moving backward. Then, the power part drives the plunger to move forward to perform high pressure injection. 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.
