Abstract

The invention discloses an intra-mold glue spraying method. A blanking female mold is positioned to a lower mold frame through a first dowel, and the blanking female mold is locked to the lower mold frame through first screws. The blanking female mold coordinates with a female mold fixing plate in a bilateral interference 0.02 MM manner, and a locking ring coordinates with the lower mold frame inan interference 0.01 MM manner. A locking ring cover plate is positioned to the lower mold frame through a second dowel and locked to the lower mold frame through second screws. A blanking male mold is connected with an upper mold frame through a male mold fixing plate and a male mold cushion plate. The blanking male mold is internally provided with a nozzle. A glue spraying pipe is connected withthe blanking male mold and a glue controller, stamped steel is cut off and enters the blanking female mold and the locking ring, a product is pressed through the locking ring, glue is cured at the normal temperature and adheres together, and after getting out of the locking ring, the stamped steel forms a product with an appointed height. According to the intra-mold glue spraying method, moldingopening for glue spraying of an injection molding machine can be avoided, glue spraying is uniform, the pasting quality is good, assembly lines can be reduced, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the field of mold processing, and in particular relates to an in-mold glue spraying method. Background technique [0002] Mold processing now refers to the processing of forming and billet tools, and also includes shearing molds and die-cutting molds. Usually, the mold consists of two parts, the upper mold and the lower mold. The steel plate is placed between the upper and lower molds, and the material is formed under the action of the press. When the press is opened, the workpiece determined by the shape of the mold is obtained or the corresponding waste is removed. Workpieces as small as electronic connectors and as large as automotive dashboards can be molded. Progressive die refers to a set of molds that can automatically move the workpiece from one station to another, and obtain formed parts at the last station. Mold processing technology includes: cutting die, punching die, composite die, extrusion die, four slide rail...
