An LED television light guide plate in-mold compression forming mold comprises a fixed mold base and a moving mold base, wherein a runner plate, a runner supporting plate and a fixed mold plate are mounted below the fixed mold base; a hot runner is mounted in the runner supporting plate; a fixed mold insert is mounted in the fixed mold plate; a backing plate is mounted on the moving mold base; anda moving mold plate is mounted on the backing plate. The LED television light guide plate in-mold compression forming mold is characterized in that a floating plate is arranged on the moving mold plate and matched with the fixed mold plate; a floating oil cylinder is connected with the lower part of the floating plate; a moving mold insert is mounted on the floating plate and fits the fixed moldinsert; a side runner is arranged between one side of the moving mold insert and that of the fixed mold insert; and the hot runner communicates with the side runner. The LED television light guide plate in-mold compression forming mold provided by the invention has the beneficial effects that after the injection and extrusion forming of a product, the interior of the product is protected against shrinkage, flow marks and the like; the smoothness and the light transmittance of the product are improved; and the product is high in quality and grade.
Description
technical field [0001] The invention relates to an in-mould extrusion molding mold of an LED TV light guide plate, which belongs to the field of injection molds. Background technique [0002] The existing technology uses injection molds to produce LED TV light guide plates, all of which use common injection pressure-holding molding technology. The disadvantage is that there are defects such as miniatures and flow marks on the light guide plate, which affect the smoothness and transparency of the product, and the product quality is poor. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the prior art, and provide a kind of in-mold compression molding of LED TV light guide plate which adopts injection extrusion molding, has no flow mark, miniature, smooth surface, good light transmittance and reliable quality. mold. [0004] The technical scheme of the in-mold compression molding mold for a LED TV light guide plate of...
