Description

Technical Field

[0001] The invention relates to an injection mold, in particular to a rubber injection processing center for multi-station continuous point injection molding. Background Art

[0002] The structure of the traditional rubber injection molding machine is mainly a lower mold clamping direct pressure structure. Two sets of fast mold clamping oil cylinders push the dynamic template and plunger to a large displacement and require a large filling pipe to fill the liquid. After the mold is clamped, the filling valve is closed, and then the high pressure is increased to realize the mold clamping and pressurization process. With the improvement of the automation level of modern factories, the traditional single rubber injection molding machine production and manual loading and unloading can no longer meet the growing production needs. Now it is difficult to recruit workers, and the labor cost is increasing year by year. The automation of rubber injection molding equipment and production lines is improved, and saving staff and increasing efficiency is the only way. .

[0003] Traditional rubber injection molding machines have a two-step mold clamping structure, a high table, a high whole machine, a large movable mold plate stroke, the product rack needs to be moved up synchronously, the moving stroke is large, the synchronization structure is complex, it is difficult to synchronize, and the cost is high; there are three-step mold clamping structures, which are complex in structure and movement, and are prone to problems during work; there are also upper-moving two-step mold clamping and three-step mold clamping structures, which are difficult to maintain. In order to further solve the problem of low production efficiency of manual loading and unloading of existing single rubber molding equipment, give full play to the labor enthusiasm of workers, reduce the labor intensity of workers, and do not affect the factory's single-piece small-batch production, the use of automated flexible production lines is the new direction of the industry.

[0004] Moreover, during the injection process, the injection speed cannot be adjusted according to the fluidity of the raw materials. When the fluidity of the raw materials is good, a slower injection speed will lead to insufficient pressure inside the mold, affecting the density and strength of the final product, while reducing the injection efficiency. When the fluidity of the raw materials is poor, a faster injection speed will cause uneven flow of the rubber raw materials in the mold, resulting in local unfilled defects, making it impossible to guarantee processing accuracy and efficiency.
