A spring top block mold device for solving mold cavity jam

Abstract

The invention discloses a spring top block mold device for solving the problem of material jam in the mold cavity. The device includes a mold main body, the mold main body is installed on a bottom plate, and a knife edge is arranged on the surface of the mold main body; wherein, a plurality of springs are installed in the bottom plate, and each spring is respectively connected with a thimble and a thimble A block action column, the thimble and the ejector block action column both extend through the mold body to above the surface of the mold body and can slide, and the ejector pin is higher than the blade, and the ejector block action column above the thimble. In the present invention, a spring ejector mold device that solves the problem of material jam in the cavity can automatically eject the insert when the mold is opened by adding a spring device at the bottom of the insert mold, and then eject the product, thereby solving the problem of die-cutting. Problems such as material jam, waste discharge, embossing and film wrinkle, etc., and keep the overall pressure stable.

Description

technical field [0001] The invention relates to the field of molds, in particular to a spring ejector mold device for solving mold cavity material jam. Background technique [0002] In communication equipment, such as the mobile phone industry, the manufacture and installation of many of its components (such as speakers) are becoming more and more miniaturized and compact, and the corresponding die-cut products (such as waterproof and breathable membranes) in processing The size is also getting smaller, the shape is often very irregular, and there are often cases where multiple layers are stacked and processed at the same time. Therefore, when using traditional engraving molds and insert molds to process components, problems such as material jams, waste discharge, embossing, and film wrinkles often occur, and are often difficult to solve. Contents of the invention [0003] In order to solve the above problems, the present invention provides a spring ejector mold device th...
