Energy Saving Good Designed 400 Ton Horizontal Rubber Injection Molding Machine


Rubber Injection Machine Common Problems:

  • First, most of them use a lower system pressure of 21/22 MPa. The nominal 300-ton model can only provide a clamping force of 2600 KN, which is insufficient. The corresponding pumps and valves are relatively cheap in Japan or Japan. Brands such as Taiwan are prone to oil leakage and damage, and their service life is not long; hydraulic pipelines also use split valves and pipes, which are prone to failure and difficult to maintain. Second, the fuselage structure design is unreasonable, and the mold opening space is insufficient. The mold must be removed to open the mold outside. The design of the guide post is not reasonable. "Bread" and so on. The three-rubber injection machine is a backward advanced late-out injection unit. Each mold needs to shoot about 20 ~ 30g of rubber material first, and the temperature of the plasticizing cylinder is low; cleaning and replacing the rubber material is very tedious and requires disassembly. In actual use, the most fatal weakness of many machines is instability, and various problems often occur that affect customer use and production. The working principle of the injection molding machine is similar to the syringe used for injection. It uses the thrust of the screw (or plunger) to inject the plasticized molten state (ie, viscous fluid state) into the closed mold cavity. The process of obtaining products after curing and setting. The injection molding machine is a cyclic process, and each cycle mainly includes: quantitative feeding-melt plasticizing-pressure injection-filling cooling-opening and taking parts. After removing the plastic part, the mold is closed and the next cycle is performed.
  • As far as the characteristics of rubber itself are concerned, injection molding has become the mainstream method of rubber product molding with its unique advantages. The injection process is to increase the temperature of the rubber compound to the state with the best fluidity through the heating of the plasticizing cylinder and the stirring and shearing of the plasticizing screw, and then inject the rubber compound in this state through a higher injection pressure. Into the cavity of the mold clamping (evacuating), pressurize and heat to vulcanize the rubber. Throughout the process, time, pressure and temperature determine the efficiency and quality of production. There is a lack of professional rubber mold manufacturers in China. Most of them are specialized in plastic molds, and straps are used to make some rubber molds. The understanding and research of rubber molds are not enough and lack of innovation. There has always been a concept in China that rubber molds are simple, easy, and low in price. In fact, it is this wrong concept that has stunted the development and growth of domestic rubber injection molding processes. In addition, there is a lack of professional injection molding technology talents, as do the product factories. At present, there is a serious lack of related personnel in the process research of rubber injection machines in domestic product factories. Hiring a process engineer from a foreign-funded company with a monthly salary of 12,000 yuan can find clues. In foreign countries, the craftsmen of product factories can make clear requirements for machines and molds, and make process adjustments and corrections based on machine capabilities and molds. However, there is a shortage of craftsmen with the ability in this area in China. Constant temperature, pressure and time, but the research and deep understanding of the injection molding process is not enough.

What Factors Affect Plasticization of Rubber Injection Machine:

For the operation and maintenance of hydraulic presses, in addition to the maintenance of general mechanical equipment, there are some special requirements. The specifics are as follows by Changzhou Jianyang
The professionals introduce you:

  1. Familiar with the role of the main hydraulic components used in this equipment, the working principle of the hydraulic system and the sequence of actions of the actuators
  2. The system can monitor the working errors of this system for a long time, especially the working pressure and the operating speed of the actuator, so as to ensure the stable operation of this system.

Before starting the hydraulic system, it is necessary to check whether all solenoid valves and moving mechanisms are in their original state and whether the oil level of the fuel tank meets the requirements.
