Description

Technical Field

[0001] This utility model relates to an injection mold, and more particularly to a multi-station continuous point injection molding rubber injection processing center. Background Technology

[0002] Traditional rubber injection molding machines primarily employ a bottom-closing direct-pressure structure. Two sets of rapid-closing hydraulic cylinders push the moving platen and plunger to large displacements, requiring a large filling pipe for fluid injection. After mold closing, the filling valve is closed, followed by high-pressure boosting to complete the mold closing and pressurization process. With the increasing automation of modern factories, the traditional single-unit rubber injection molding machine and manual loading / unloading can no longer meet the growing production demands. Recruiting workers is difficult, and labor costs are rising annually. Therefore, upgrading rubber injection molding equipment and production lines to automation, reducing manpower, and increasing efficiency are essential.

[0003] Traditional rubber injection molding machines have two-step mold-closing structures, which are high on the table, make the whole machine tall, have a large moving platen stroke, and require the product rack to move upwards synchronously. This involves a large moving stroke, a complex synchronization structure, and is difficult to synchronize, resulting in high costs. Three-step mold-closing structures are also available, but these are complex in structure and operation, and prone to problems during operation. There are also top-mounted two-step and three-step mold-closing structures, which are difficult to maintain. To further address the low production efficiency of manual loading and unloading on existing single-unit rubber molding equipment, to maximize worker productivity, reduce worker labor intensity, and without affecting small-batch single-piece production, the adoption of automated flexible production lines is the new direction for the industry.

[0004] Furthermore, during the injection process, the injection speed cannot be adjusted according to the fluidity of the raw material. When the raw material has good fluidity, a slower injection speed will result in insufficient pressure inside the mold, affecting the density and strength of the final product and reducing injection efficiency. On the other hand, when the raw material has poor fluidity, a faster injection speed will result in uneven flow of the rubber raw material in the mold, causing defects such as incomplete filling in certain areas. Consequently, neither processing accuracy nor processing efficiency can be guaranteed. Utility Model Content
