Secondary core puller for inclined fixed hole of fog lamp shell die for vehicle

Abstract

A secondary core puller for an inclined fixed hole of a fog lamp shell die for a vehicle comprises an upper compound plate and a lower compound plate; the upper compound plate is connected with a fixed template; a die pin is arranged on the lower compound plate; a thimble plate is arranged in the die pin and connected with a thimble; a movable template is arranged on the die pin; a movable die insert is installed on the movable template; the movable template, the movable die insert and the fixed template form a die cavity; a formed fog lamp shell is installed in the die cavity; an inclined fixed hole is formed in the lamp shell; and the inclined fixed hole is provided with an inclined hole chip. The secondary core puller is characterized in that an inner slide block is arranged in the movable template; an inclined slide slot and a push block are arranged on the inner slide block; an outer slide block is arranged above the inner slide block; a push slot is arranged on the outer slide block and matched with the push block of the inner slide block; the inclined hole chip is matched with the inclined slide slot after penetrating the outer slide block; a fixed frame is fixedly arrangedon the outer wall of the movable template; a core pulling cylinder is installed on the fixed frame; and a piston rod of the core pulling cylinder is connected with the inner slide block. By adopting a secondary core pulling and de-molding mode, the product can be automatically ejected via an injection mold, thereby high production efficiency is acquired.

Description

technical field [0001] The invention relates to a secondary core-pulling mechanism for an oblique fixing hole of an automobile fog lamp shell mold, and belongs to the field of plastic molds. Background technique [0002] Fixing holes are formed in the lamp housing of the fog lamp of the automobile, and screws are installed in the fixing holes to be fixed with the vehicle body. Most of the fixing holes of existing fog lamp housings are straight holes, which can be directly pulled out after injection molding, but the fixing holes need a certain depth to be installed firmly, so the straight fixing holes need to occupy the inner space of the fog lamp housing , that is, the hole wall of the fixing hole needs to pass through the shell wall of the lamp housing, resulting in an unattractive appearance of the lamp housing. Therefore, some people have also designed oblique fixing holes, which not only meet the hole depth required for assembly, but also do not penetrate the wall of th...

AI Technical Summary

Problems solved by technology

However, when the oblique fixing hole is injection molded, the core-pulling core in the hole also needs to be installed obliquely, so that the core cannot be pulled directly, resulting in difficulty in demoulding
