Description

Technical Field

[0001] This utility model relates to the field of rubber injection molding equipment, and in particular to a high-efficiency, compact rubber injection molding machine with adjustable mold. 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 hydraulic filling. After mold closing, the filling valve is closed, followed by high-pressure boosting to achieve the mold closing and pressurization process. After product vulcanization, the filling valve is opened again, and the rapid-closing hydraulic cylinders quickly pull the moving platen back to its lowest position. During mold closing and opening, a large amount of hydraulic oil is required to coordinate with the plunger's lifting and lowering operations; therefore, a sufficiently large oil tank is also necessary.

[0003] Traditional rubber injection molding machines have two-step mold-closing structures, resulting in high table height, overall machine height, and a large moving platen stroke. The product holder needs to move upwards synchronously, leading to a large stroke, complex synchronization structure, difficulty in achieving synchronization, and high costs. Three-step mold-closing structures are also available, but these are complex in structure and operation, prone to problems during operation. There are also top-moving two-step and three-step mold-closing structures, which are difficult to maintain. Furthermore, the quick-change mold structure in the upper mold section, including the mold-changing transmission cylinder assembly, has a release platen connected to the linkage plate and located below it. The release platen is connected to the heat insulation plate via a side-end locking device, further contributing to mold damage and injection runner misalignment. Moreover, traditional rubber injection molding machines cannot meet the needs of customers with requirements regarding space area, height, and worktable size. Utility Model Content

[0004] The purpose of this invention is to provide a high-efficiency, compact, and adjustable mold rubber injection molding machine, which solves the problems of large footprint and inconvenient mold adjustment in ordinary rubber injection molding machines.

[0006] The upper mold body operating cylinder group includes an upper mold side control cylinder group located at the side end of the injection cavity and a vertical movement control and limiting cylinder group located between the top injection feeding frame structure and the outside of the injection cavity.

[0007] The injection base frame structure includes a bottom mold frame, a hydraulic chamber located in the middle of the bottom mold frame, a bottom mold control cylinder located between the bottom mold frame and the hydraulic chamber, and a bottom mold side displacement controller located on the outside of the bottom mold frame.

[0008] The top injection feeding frame structure includes a feeding melting chamber seat, a main control hydraulic column located on the upper part of the feeding melting chamber seat, a material strip guide located on the side end of the feeding melting chamber seat, and a main control cylinder connected to the lower part of the feeding melting chamber seat and between it and the injection chamber.
