Forming device of novel rubber spherical hinge mold opening mode and opening method of novel rubber spherical hinge mold opening mode

Abstract

The invention discloses a forming device of a novel rubber spherical hinge mold opening mode and an opening method of the novel rubber spherical hinge mold opening mode. The forming device comprises a rack, wherein two fixing beams arranged side by side are erected on the rack, the middle area between the two fixing beams is a forming station, the areas at the two ends are feeding and discharging stations, and two movable lower mold assemblies are installed between the fixing beams in a guiding mode; the lower mold assembly comprises a fixed lower mold body and a movable lower mold body; a top plate is erected above the forming station, an upper mold assembly is installed below the top plate and comprises a fixed upper mold body and a movable upper mold body, and the movable upper mold body is driven by gear pull rod mechanisms at the two ends of the movable upper mold body to move; and the upper end surfaces of the fixed lower mold body and the movable lower mold body and the lower end surfaces of the fixed upper mold body and the movable upper mold body are respectively provided with cavities which are mutually folded and are used for forming spherical hinge rubber. The machining efficiency is improved, the opening mode of the gear pull rod mechanism is good, stability is good, long-term use can be achieved, operation is simplified, and the requirements for batch machining and production are met.

Description

Technical field: [0001] The invention relates to the field of production and processing of a thrust rod, and mainly relates to a molding device and an opening method of a new rubber ball hinge mold opening mode. Background technique: [0002] The thrust rod of the car is mainly composed of a ball head, a ball joint and a sleeve. When the car starts, accelerates and brakes, the rubber ball joint will frequently receive tension and pressure. Due to the poor ability of the rubber to withstand the tensile force, in order to improve the service life , when the rubber ball joint is in use, the rubber is in a compressed state. According to the way of rubber precompression, it can be divided into: axial compression ball joint, radial compression ball joint and two pairs of T-mounted compression ball joints. At the same time, it is vulcanized together with the mandrel through the vulcanization process. Due to the characteristics of the ball head in the middle of the mandrel, it needs...

Problems solved by technology

[0003] In order to ensure the convenience of picking and unloading materials, the structure of double-shuttle inclined guide pillars has appeared after technical improvement, such as patent: 202020586387, which adopts the method of separating the movable upper mold and lower mold and the opening and merging of inclined guide pillars. After the glue is vulcanized at high temperature and integrated, the movable lower mold and the fixed lower mold of the lower mold are first opened by raising the inclined guide column. The ejector mechanism can push out the ball hinge to separate it and realize the forming of the ball hinge. However, since the mandrel will move with the opening and tightening of the inclined guide post after it is clamped and fixed, the positioning of the mandrel There will be a certain deviation, which will affect the vulcanization molding specifications of the rubber. The quality of the formed product is unstable, and the structure of the inclined guide column is adopted. The inclined guide post is easy to wear, so that the matching degree of the movable lower mold and the fixed lower mold will affect its overall service life, and most of the existing mold forming is a set of upper molds corresponding to a set of lower molds, so in the molding process Among them, each loading and unloading will affect the operation time, the production efficiency is low, and it cannot meet the requirements of batch processing and production
