Problems solved by technology
[0002] The core-pulling of the front mold slider of the existing mold is driven by the shovel structure to do the lateral demoulding movement of the front mold slider, which is the movement of the front mold slider horizontally away from the cavity, but for the front inner side with a horizontal inward For protruding products, the existing front-mold slider core-pulling cannot meet the requirements of one-time molding of the product, which requires secondary processing of the product, reducing the production efficiency of the product, and due to the secondary positioning, the processing accuracy of the product is low

The invention provides a loose core structure of a front mold slider insert. Due to adoption of the loose core structure, a product with a horizontal inward bulge on the inner side at the front part can be formed in an injection molding mode for one time, the production efficiency of the product is improved, and the machining precision of the product is high. The loose core structure comprises a front mold and a rear mold, wherein a forming chamber is formed between the front mold and the rear mold; the product is arranged inside the forming chamber; the product is provided with the horizontal inward bulge on the inner side at the front part. The loose core structure is characterized by further comprising the front mold slider insert, wherein the outer side of the lower end of the front mold slider insert goes deep into the inner side of the horizontal inward bulge of the product; the lower end surface of the front mold slider insert is clung to the forming chamber; the outer side of the upper end of the front mold slider insert is supported on the front mold; the upper end surface of the front mold slider insert is clung to the lower end surface of a plate A; the inner side surface of the front mold slider insert is an inner side inclined plane which slants outwards from bottom to top; a shovel machine is positioned inside a mounting chamber of the front mold.
Description
technical field [0001] The invention relates to the structural technical field of product molds, in particular to a core-pulling structure of a front mold slider insert.
