Description

Technical Field

[0001] The utility model belongs to the technical field of molds and relates to an inner drawing mechanism of a slide block of a mold for a housing of a front combination lamp of an automobile. Background Art

[0002] The housing of the front combination lamp of an automobile is generally formed by injection molding. When the housing of the combination lamp is injection molded, a plurality of core pulling assemblies need to be arranged in the mold. Among them, the core blocks in most of the core pulling assemblies are inserted into the molding cavity from the outside to the inside of the mold. However, the core blocks in a small number of core pulling assemblies need to be inserted from the inside to the outside of the mold to the raised position at the bottom of the molding cavity. Since this position is located directly below the molding cavity, the driving assembly of the core block cannot be arranged on the upper mold plate to drive the core block to be pulled out of the core block by the movement of the upper mold plate without setting a cylinder. Although the core pulling of the core block can be achieved by setting a cylinder on the lower mold plate, because the cylinder is arranged on the inside of the mold, the high temperature inside the mold will affect the service life of the cylinder.
