Thermoforming Folding Clamping Device

Abstract

The invention discloses a hot-press molded foldable material-clamping device and relates to the technical field of hot press molding. The hot-press molded foldable material-clamping device comprises a fixed framework and a plurality of elastic material-clamping parts connected with the side wall of the inner peripheral side wall of the fixed framework, wherein the fixed framework is provided with a movable fork frame therein. The fork opening end of the movable fork frame is hinged with the fixed framework. The fixed framework is further connected with the movable fork frame by a spring; and the elastic material-clamping parts are arranged on the inner peripheral side wall defined by the movable fork frame and the fixed framework. Compared with a conventional hot-press molded material-clamping device, the hot-press molded foldable material-clamping device provided by the invention has high efficiency, can initiatively feed materials into a mold cavity, and has high material-feeding stability and reliability. A molded product has high quality, has no fold or rolling-up phenomena, and has increased product thickness.

Description

technical field [0001] The invention relates to the technical field of thermocompression molding, in particular to a clamping device for thermocompression molding moulds. Background technique [0002] Rubber body products such as automobile carpets need to keep the blank in a tensioned state during the hot pressing process. The traditional method is to use a clamping frame to clamp and fix the blank. This clamping frame includes two fixed frames, the upper and lower. The billet is placed between two fixed frames, and the billet is tensioned and fixed by pressing up and down. This structure cannot realize automatic feeding. When producing products with a large tensile modulus, the product will have serious deformation of the surface texture and edges. The problems of serious roll-up, thinning of both ends and serious waste of material. For this reason, the applicant has recently applied for an invention patent named as a clamping device for automobile carpet thermoforming, a...
