Abstract

The invention relates to the field of injection molds, in particular to a structure allowing glue to be injected from the bottom of a sliding block. The structure comprises a hot nozzle, an upper moving plate, a die core, a first ejector rod, a second ejector rod, an inclined guide column, the sliding block, a mold plate, an upper ejector plate, a lower ejector plate and a bottom plate. By the adoption of the structure, the integrity of product appearance can be ensured, and smooth filling is ensured as well; the injection molding pressure is greatly reduced, and the problems of mold expansion, deformation, material shortage and the like caused by excessive pressure are avoided; the energy consumption and cost are saved, a material path is shorter, and the material cost is reduced; and a gate is formed in the non-appearance surface without affecting the appearance quality of the product.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a structure for feeding glue from the bottom of a slider. Background technique [0002] There are mainly two kinds of existing technical solutions, one is that the glue feed point is directly set on the product surface, which will affect the integrity of the product appearance. The other is that it is necessary to sacrifice the best glue-feeding position and choose a less-than-ideal glue-feeding position, which will cause various problems in the injection molding process, such as mold swelling, deformation, and material shortage caused by excessive pressure. These problems may require the selection of a larger-sized injection molding machine, or it may take several process adjustments to reduce the pressure. This is undoubtedly a loss of equipment energy consumption and labor costs. In addition, the flow path is too long, which increases the material cost. Contents of the invent...
