Forming device and process for rubber sponge barrel-shaped sectional material

Abstract

The invention discloses a device and a process for forming a rubber sponge barrel-shaped sectional material. The device comprises a sizing grinding core rod, a sizing die and a forming die lower die,wherein the sizing die and the forming die lower die are the same in shapes, the sizing grinding core rod is matched with the tops of the sizing die and the forming die lower die, a first U-shaped barrel-shaped filling cavity is arranged in the sizing die, and a second U-shaped barrel-shaped filling cavity is arranged in the forming die lower die; by means of the device, the sponge barrel-shaped sectional material which is uniform and stable in foam hole size, of a micropore closed structure and low in apparent density can be prepared through the processes of sizing, vulcanizing and aftertreatment sectional forming; and the device has the advantages of simple structure, simple process, practicability and high efficiency.

Description

technical field [0001] The invention relates to the technical field of rubber sponge production, in particular to a molding device and process for rubber sponge barrel-shaped profiles. Background technique [0002] At present, rubber sponge checks have been widely used, but most of the rubber products continue to use traditional molds and traditional rubber sponge product molding processes. According to the amount of rubber filling in the molding cavity, there are two types: 1) full mold vulcanization, that is, rubber Fill the entire mold cavity; 2) Under-full mold vulcanization means that the rubber material does not fill the entire mold cavity. Both processes have problems such as uncontrollable structure, uneven cell structure, and high porosity. Contents of the invention [0003] In order to overcome the deficiencies of the above-mentioned prior art, the object of the present invention is to provide a molding device and process of a rubber sponge barrel-shaped profile....

[0002] At present, rubber sponge checks are widely used, but most of the rubber products continue to use traditional molds and traditional rubber sponge product molding processes. According to the amount of rubber filling in the molding cavity, there are two types: 1) full mold vulcanization, that is, rubber Fill the entire mold cavity; 2) The rubber material does not fill the entire mold cavity when the mold is not fully vulcanized. Both processes have problems such as uncontrollable structure, uneven cell structure, and high porosity.
