Main Features Of Rubber Injection Machine:

With the rapid development of power-saving injection machines, many companies continue to choose power-saving rubber injection machine equipment as a way of production by manufacturers. The real use of mechanical equipment mainly has the following characteristics:

1. The full hydraulic injection machine has many unique advantages in forming precise and complex shapes. It has evolved from the traditional single-cylinder liquid-filled and multi-cylinder liquid-filled type to the current two-plate direct-pressure type. The direct pressure type is the most representative, but its control technology is difficult, the machining precision is high, and the hydraulic technology is difficult to master.
2. All-electric rubber injection machine has a series of advantages, especially in environmental protection and energy saving advantages, it is reported that the current advanced all-electric injection machine can achieve 70% power saving, in addition, due to the use of servo motor injection control accuracy Higher, the speed is also stable, and can be adjusted in multiple stages. However, all-electric injection machines are not as durable as full-hydraulic injection machines, and full-hydraulic injection machines must use servo valves with closed-loop control to ensure accuracy, and servo valves are expensive and costly.
3. The electric-hydraulic injection machine is a new type of injection machine that integrates hydraulic and electric drive. It combines the high-performance and all-electric energy-saving advantages of the full-hydraulic injection machine. This electric-hydraulic combination is combined. The injection machine has become one of the development directions of the injection machine technology.

Specifications of Rubber Injection Machine:

Expressed in terms of the maximum injection volume of the machine, the unit is cubic centimeter; the maximum injection volume indicated by the general equipment manufacturer is the theoretical maximum injection volume, the deviation caused by the actual machine manufacturing and use, so that the actual maximum injection volume of the machine Deviated from the maximum theoretical injection volume;

• The theoretical injection volume refers to the maximum amount of plasticized melt (cm3) that can be pushed out by the injection device in the maximum stroke of the screw (plunger) in the injection molding machine. The theoretical injection volume is the main performance parameter of the injection molding machine. From this parameter, the processing capacity of the injection molding machine can be known, so that the maximum quality of the injection molded plastic article can be determined.
• The national standard GB/T 12783-1991 stipulates that the theoretical injection amount is expressed by mass (g) or volume (cm3) when the material is molten. At present, domestic and world countries use volume (cm3) to mark more, because the material volume is independent of the density of the material's molten state. This marking method is suitable for the measurement of any plastic.
• Since there is a mutual movement clearance between the outer diameter of the screw (plunger) and the inner diameter of the barrel, when the screw (plunger) pushes the melt forward, the diameter of the nozzle is reduced and the friction between the material and the inner wall of the barrel is affected. A part of the material will flow back from the gap. In addition, there is a certain amount of shrinkage that needs to be replenished when the melt cools. Therefore, the actual injection volume of the rubber injection molding machine is smaller than the theoretical injection amount, and the calculation needs to be corrected by the coefficient K value, the size of the K value and the structure and parameters of the screw (plunger), the outer diameter and the gap, the injection force, Factors such as melt flow rate, back pressure, mold structure, product shape, and plastic properties. When the screw head has a check valve, the K value is 0.9; if only the reflow of the melt is considered, the K value is 0.97.
• Actual injection volume
• If the quality of the plastic product is known, when the injection molding machine is selected, the volume of the plastic in the molten state is converted into the density.
• If the type of injection molding machine is selected according to the quality of the single piece of plastic products (note: the quality of the single piece of plastic products should be 70% to 90% of the theoretical injection volume of the injection molding machine), select this type of injection molding machine to produce this plastic product as the most Good plan. If the quality of the plastic product is less than 40% of the theoretical injection volume of the injection molding machine, the production of the plastic product by the injection molding machine reduces the equipment utilization rate of the injection molding machine and greatly increases the production cost of the plastic product.

Expressed in terms of the maximum clamping force of the machine, the popular unit is tons;

In addition to the above two most important parameters, the size of the device template is also an important parameter of the device;

The basic structure of the rubber injection molding machine:

1. Plasticizing injection unit: The plasticizing injection unit is the core part of the rubber injection machine. The focus burning, air entrapment, density uniformity and convenience of changing the rubber compound play a decisive role.
2. Clamping device: The clamping unit is the main part of the rubber injection machine, which plays a key role in vulcanization quality, output efficiency and convenient operation.
3. Control system: The control system is the brain of the rubber injection machine, which plays a decisive role in machine precision, stability and energy consumption;
4. Safety protection: Safety protection is an essential part of the rubber injection machine and plays a role in ensuring safe production. The safety protection design mainly considers the safety protection device of the equipment and the humanization of the production process from the perspectives of convenience, efficiency and habit of the worker, and clearly guides and consolidates the foundation of production and development.
