The working principle of Vertical Rubber Injection Molding Machine: the rubber after the mixing process is automatically screwed into the storage barrel according to the preset metering through the screw, pre-plasticized and kept warm, and then injected into the product cavity of the mold. , heating vulcanization molding. Widely used in the production of rubber injection molding products: automotive shock absorber system accessories, air springs, tire capsules, power transmission insulators, arresters, cable accessories, rubber seals, medical devices, chemical valves, shoe soles, industrial and mining rain boots, casters, small tires , Navigation and aerospace, electronic communications and other silicone, rubber products molding production!
The main features of the Rubber Injection Molding Machine:
- The injection molding method simplifies the production and processing technology; realizes the rapid and uniform vulcanization of rubber products, and shortens the production cycle;
- The product size is accurate, the physical and mechanical properties are stable, and the quality is high, which is especially suitable for the forming and vulcanization of thick-walled products;
- Improve production efficiency, high pass rate; less product burrs, no need to trim; less loss, save rubber;
- The operation is simple, the labor intensity is reduced, the service life of the mold is improved, and the degree of mechanization and automation is high;
Rubber injection machines and their molds have complex mechanisms, large investment, and high level of maintenance requirements, and are widely used in the production of various large-scale rubber products.
At present, there are many types of rubber injection machines on the market. According to the configuration of machine components, there are horizontal, vertical, angle, multi-station injection machines and so on.
The external characteristics of the horizontal rubber injection machine are similar to that of the injection molding machine. Because the main structure of this type of injection machine is a horizontal mold opening method, it cannot realize functions such as mold shifting and top mold, and cannot use multi-layer complex molds. There are few fields of application.
The external characteristics of the vertical rubber injection machine are mainly that the injection cylinder and the material storage cylinder are placed on the top of the upper machine base, and the injection is directed from top to bottom. The structure of the main machine is the upper and lower mold opening method, which is widely used in the production of various rubber products.
The external characteristics of the angle type rubber injection machine are mainly that the injection cylinder, the material storage cylinder and the feeding system traverse the inside of the upper machine base, and the lateral conversion angle of 90 degrees (referred to as the angle type or simply the horizontal type) is injected into the mold cavity. The upper and lower mold opening method is widely used in the production of various rubber products.
The external features of the multi-station rubber injection machine are mainly that the injection cylinder and the material storage cylinder are placed on the top of the upper machine base, and the injection is directed from top to bottom. The host structure is a multi-station independent upper and lower mold opening mode, and the injection system can be moved to each station to independently complete the injection function. Duplex is the most widely used.
