Embodiment
Prepare mould below in conjunction with specific embodiment to resin cast thing oxygen index test described in the utility model to be described further, but protection domain of the present utility model is not limited to this.
Embodiment 1
Mould is prepared in the test of a kind of resin cast thing oxygen index, and described mould of preparing comprises base plate 1, U-shaped chamber plate and cover plate 2 from top to bottom successively; Described U-shaped chamber its surrounding of plate is the sheet frame be made up of two horizontal connecting links 5 and two vertical connecting links 6, and it is inner is multiple module unit be made up of U-shaped inside groove connecting link 7, U-shaped water jacket connecting link 8 and U-shaped chamber groove 9; There are multiple trapezoidal sprue 13 and an overflow groove 14 in described its front end of cover plate 2, and wherein there is cutting mouth rear end; Described sprue 13, overflow groove 14 are communicated with U-shaped chamber groove 9 with cutting mouth; Described base plate 1 there is setting nails 11, for fixing U-shaped inside groove connecting link 7 and U-shaped water jacket connecting link 8, forms close-connected structure; Respectively there is a carrying handle 12 described cover plate 2 upper wall both sides; Described cover plate 2 cover plate is fixed with the cutter 3 being realized lifting by elastic force apparatus; Described cutter 3 bottom connects the cutting blade 4 matched with cutting mouth; Described cover plate 2 inside surface, U-shaped chamber groove 9 and base plate 1 inside surface and the cutting blade 4 after closing form mold die cavity altogether; Described horizontal connecting link 5 and vertical connecting link 6 thickness are 10mm, it all have the eyelet passed for screw 10; Described U-shaped inside groove connecting link 7 and U-shaped water jacket connecting link 8 thickness are 10mm, and rectilinear end length is 150mm, and distance is 10mm between the two.
