250 Ton OEM Horizontal Rubber Injection Molding Machine High Repeatability Precision



Pre-plastic Injection Structure Thoery:


  1. The pre plastic injection device by plasticizing and injection parts, it is the role of uniform heating and plasticizing rubber, through the nozzle glue plastic is injected into the cavity, after the injection pressure is maintained, the rubber mold cavity is maintained in the set under the pressure of a certain period of time, to prevent the plastic material flow caused by inverse loose and uneven surface tissue products.
  2. The pressure is generally 80-120MPa, and the high person can reach the actual injection pressure of 60%-80%. According to the experience, when the pressure pressure is about 80% of the actual injection pressure, the quality of the products is high.
  3. Therefore, the requirements for the injection device are: strong plasticizing capacity, sufficient injection pressure, injection speed, and accurate measurement of feed.
  4. The preplastic injection device is usually divided into several types of screw extruding, plunger, reciprocating screw and preplastic screw.
Hydraulic Driving Device of The Injection Machine:


  1. The basic types of injection machine are mechanical transmission (motor and gear reducer), hydraulic transmission (oil pump and its components), hybrid drive (injection device for liquid, and mechanical clamping device for mechanical transmission) three kinds.
  2. Compared with the hydraulic transmission and mechanical transmission, generally has the following advantages: speed and pressure and stroke can be adjusted, the adjustment of the way is also more convenient, easy to direct numerical pressure; easy to realize the pressure and speed of program control and centralized control machine; smooth movement, with self lubrication characteristics, easy to implement prevention; overload protection.
  3. The disadvantages are: speed and pressure change of temperature and temperature will affect the system's speed and position accuracy; no precise mechanical transmission; many elements, relatively low efficiency (power consumption, water consumption, fuel consumption is relatively large); technical requirements for the maintenance of high noise and oil pollution.
  4. With the continuous improvement of the manufacturing and maintenance level of the hydraulic components, the above shortcomings are overcome in different degrees. At the same time, the injection machine requires more and more control technology. Therefore, at present, the hydraulic transmission type injection machine is the most.
  5. The advantages of the injection machine using the hydraulic transmission technology include: because of the system related reasons, the hydraulic transmission also has some advantages that the motor does not have. The hydraulic transmission directly produces a linear movement without any mechanical conversion, and the range of the ratio of strength to speed is very wide. The hydraulic system is more overloaded than the load, and the energy of the storage can be used instantly.


Injection Electronic Control Devices:
  1. The advanced injection machines in the world usually use the microcomputer controlled closed loop control system. The system includes keyboard input, screen display, system operation, system test, signal feedback and correction.
  2. The operator can enter instructions or data according to the problems displayed on the screen, such as the temperature of the machine barrel, the distance of the opening and closing, the injection pressure, the injection speed, etc. After the input is completed, the system will run according to the input data or instructions.
  3. At the same time, the microcomputer processing system starts monitoring and detecting whether the actual data and the setting data are consistent. If it is found that there is difference between them, it will feedback to the processing system to correct it in time.
  4. This not only ensures the reproducibility and repeatability of the products, but also realizes the rapid adjustment of the machine. At the same time, the machine tool has a storage system, which can store the current production data so that the next production can be used.
Machine Main Applications:
  1. Oil seal type rubber, rubber key, rubber for automobiles, ordinary inductrial rubber, medical rubber, trademark rubber, diamond cutters, national defance inductry, rubber toys, melamine, resin forming, plate work, etc.
  2. The rubber injection machine is used to produce auto spare parts,industral spare parts,electric appliances insulated spare parts,sealing washer,antivibration pad,toy and bodybuilding rubber parts,etc.
  3. It has short production time,good injection molding quality,stable physicome chanical character and precister and precise dimension.It is especially good for producing rubber products of complicated shape,thick wall or with embeddeb parts.
