Solid 300 Ton Horizontal Rubber Injection Molding Machine For Automotive Parts

Solid Silicone 300 Ton Horizontal Injection Machine For Silicone Automotive Parts

Main Features Of Rubber Injection Machine:

1. Simplify the process, which can realize high temperature and rapid vulcanization of rubber products and shorten the production cycle;
2. The product size is accurate, physical and mechanical properties are uniform, high quality, especially suitable for the formation of thick-walled products;
3. The high rate of genuine, less raw edges;
4. Simple operation, reduced labor intensity, high degree of mechanization and automation;
5. The mechanism of the injection machine and its mold is relatively complicated, the investment is large, the maintenance and maintenance level is relatively high, and it is mostly used for the production of large-volume molded products;
6. At present, there are many types of injection machines in the world, which are divided into plunger type and screw type according to the plasticizing method of the rubber compound; hydraulic type and mechanical type according to the type of machine transmission; according to the type of the mold clamping device, there are straight Press type, hydraulic mechanical type and secondary action type; according to the configuration of the machine parts, there are bedroom, vertical, angle, multi-mode injection machine and so on.

Basic Problems of Rubber Injection Machine:

1. In order to solve the shortcomings of the above two injection machines, people combine these two injection machines to make up for each other, which is the screw that is currently used more.
2. Plunger injection molding machine. The injection part of this machine is mainly composed of a screw plasticizing system and a plunger injection system. The injection molding process is as follows:
3. The cold compound is fed into the screw plasticizing system. After the rubber is plasticized by the screw, it is squeezed into the plunger injection system, and finally the rubber is injected into the cavity by the plunger. for
4. In order to make the rubber flow in a certain order, a check valve is installed at the end of the screw extruder, and the plastic material is plasticized and then enters the injection system through the check valve.
5. The plunger is pushed up, and the rubber does not go out of the nozzle because the nozzle passage is narrow and the resistance is large. When the plunger injects the compound from the nozzle into the cavity at a high pressure,
6. Because of the action of the check valve, the rubber does not flow back into the injection machine. Since this injection molding method combines a plunger type injection machine and a screw type injection machine
7. The advantage is that it can produce large, high quality rubber products.
8. Plasticizing systems and injection system installation methods, sometimes there may be some defects, because the glue first injected into the injection chamber is finally injected into the cavity,
9. This may cause the rubber which is in contact with the end face of the plunger to stay for too long to cause vulcanization, which may cause problems such as waste. Large devices are more prone to this kind of
10. Happening. A first-in, first-out injection machine can solve this problem.
11. Although the rubber 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,
12. The plunger is in the front position, and when the plasticized rubber enters the injection chamber from the front end of the screw through the plunger, the plunger starts to retreat under the pressure of the rubber material.
13. Until the injection chamber is filled with the required injection volume, the plunger stops moving backward. Then the power part drives the plunger to move forward, high pressure injection, and another
14. 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.
