Abstract
Description
Technical Field
[0001] This utility model relates to rubber injection molding machines, and more particularly to an integrated large-tonnage rubber injection molding machine. Background Technology
[0002] A rubber injection molding machine is a primary molding device used to produce various shapes of rubber products from thermosetting rubber using rubber molds. During operation, the machine rolls strips of rubber raw material into a storage cylinder for plasticization, then injects them into an injection barrel. The injection unit then injects the rubber from the injection barrel into a rubber mold, where it is vulcanized and molded to produce rubber products of different shapes.
[0003] Existing rubber injection molding machines consist of an injection molding frame and a hydraulic control system. The pressure tonnage of the rubber injection molding machine is determined based on the power of the hydraulic output. However, for high-tonnage rubber injection molding machines, the hydraulic pressure output needs to be preheated to a certain temperature before hot pressing of the mold. Furthermore, the hydraulic control system of existing rubber injection molding machines is a flat-layout type, which results in a large footprint and limited site layout. Utility Model Content
[0004] The purpose of this invention is to provide an integrated large-tonnage rubber injection molding machine that solves the problems of slow oil heating effect and unreasonable local oil control structure in ordinary rubber injection machines.

The rubber injection molding structure includes an injection molding frame mechanism and an oil control equipment structure. The oil control equipment structure includes an electrical control operating box, a pressure supply oil tank disposed inside the electrical control operating box, an oil control motor disposed on the pressure supply oil tank, and an oil-gas circuit controller. The oil-gas circuit controller is connected to a mounting platform on one side of the electrical control operating box and a warm oil equipment group disposed on the mounting platform. The warm oil equipment group is connected to the oil-gas circuit controller, and the oil-gas circuit controller is connected to the injection molding frame mechanism.
[0006] The heated oil equipment assembly includes an assembly cover, a heated oil chamber located in the assembly cover, a booster motor located on the upper part of the built-in booster chamber, a heating block assembly located in the heated oil chamber, a heated oil radiator, and a heated oil output pipeline connected to the heated oil chamber.
[0007] The injection molding machine frame mechanism includes a bottom connecting seat, a hydraulic base located on the top of the bottom connecting seat, a bottom mold connecting platform located on the top of the hydraulic base, a bottom mold drive cylinder located between the bottom mold connecting platform and the hydraulic base, a central sliding column assembly located on the top of the bottom mold connecting platform, an upper mold base located on the top of the central sliding column assembly, an upper mold connecting structure located at the bottom of the upper mold base, and a downward drive main cylinder located on the top of the upper mold base.
