250 Ton Horizontal Silicone Injection Machine With Infrare Camera Two Stage Injection

Application for Rubber Injection Machine Information:

1. The rubber injection molding vulcanizing machine is referred to as the rubber injection molding machine, and is one of the three molding vulcanizing machines in the industrial rubber molding products. In terms of number, (hot press molding machine) is much more than a rubber press molding machine (injection molding machine), occupying a total of 1/4 or more.
2. Although the cost of the rubber injection machine itself and its mold is higher than that of the rubber flat vulcanizing machine, but because the injection machine is advantageous for mass production, the production obedience and product quantity are greatly improved, and the material consumption and heat energy consumption are also correspondingly low. As a result, the ultimate cost of land has fallen, and it has been favored and widely accepted by large rubber factories. In recent years, due to the emergence of motorized mobile rubber injection machines suitable for small and medium-sized production, many specialized small and medium rubber factories have begun to choose.

5. Rubber injection molding machine pre-plastic injection device
6. The pre-plastic injection device is composed of plasticized and injection parts. Its function is to uniformly heat and plasticize the rubber compound. The plasticized rubber compound is injected into the cavity through the nozzle, and the injection pressure is held to make the glue in the cavity. The material is connected for a certain time under the set pressure, in order to prevent the rubber material from flowing backwards, resulting in loose structure and uncompromising appearance. The pressure of the holding pressure is usually 80-120 MPa, and the high one can reach the actual injection pressure of 60%-80%. According to the credential history, when the pressure of holding pressure is about 80% of the actual injection pressure, the amount of finished product obtained is higher than that. Therefore, the requirements for the injection device are: strong plasticizing power, sufficient injection pressure, injection rate, and accurate metering of the feed.

8. Over the years, with the rapid growth of modern high technology, higher requirements have been placed on the amount of finished rubber. However, the demand for large-scale rubber products has also increased greatly. The screw reciprocating injection machine has a certain limit of the capacity and pressure of the injected finished product. The screw plunger injection molding machine has gained new growth and application. The new plunger type injection device with pre-plastic device installs the hydraulically driven plasticizing screw in the injection piston and accepts the "first-in-first-out" (FIFO) injection method. The layout is shown in Figure 1. The compound is still plasticized using a screw-barrel, which typically places the injection cylinder symmetrically on either side of the screw. When injecting, the axial position of the screw and the barrel is stable, and the check valve at the head of the plunger closes the groove, and the screw is injected into the cavity with the plunger of the rubber injection molding machine.

Main Catagories of Rubber Injection Machine:

Rubber injection molding machine structure: There are many types of rubber injection molding machines. So far, rubber injection molding has gone through three stages: plunger injection, screw reciprocating injection and screw, Rod-plunger injection. Plunger injection molding machine

• The earliest rubber injection molding machine used a plunger injection molding machine. The injection molding method is: after feeding the rubber material from the feeding port to the barrel, it is outside the barrel.
• The heater of the part heats and plasticizes the rubber material so that the rubber material reaches a temperature that is easy to inject without being scorched. Finally, the plasticized rubber is high by the plunger
• Press into the mold. In fact, this injection method cartridge is mainly used for injection, supplemented by heat plasticization. Because rubber is a poor conductor of heat, pass
• The thermal efficiency is low. If the rubber is heated only by heat conduction, the temperature of the rubber compound rises too slowly and the plasticization is uneven. Therefore, it is necessary to first heat the rubber compound.

The machine is heated and heated to a certain extent before being fed into the injection machine. Therefore, although the injection molding method has a simple structure and a low cost, the injection molding method requires
It is necessary to configure the heat mixer and the rubber mixing workers, thereby increasing the equipment cost and the labor intensity of the workers. The most important thing is that the injection molding method has low production efficiency.
Uneven, which affects the quality of the product.
The rubber injection machine has the following 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.
