Mold for large-size uniparted hyperboloid injection molding part

Abstract

The invention discloses a mold for a large-size uniparted hyperboloid injection molding part. The mold comprises a front template, a hot-runner plate, a mold A and a mold B which are arranged from top to bottom sequentially, wherein pad bearing steps bulged on the edge of a cavity of the mold A are formed on a forming surface of the mold A, runner slots extending to the cavity are formed in the pad bearing steps, and hot sprues are arranged on the hot-runner plate and penetrate through the mold A to extend to the runner slots; a first core-pulling slider and a second core-pulling slider which are horizontally and coaxially butted are arranged between the mold A and the mold B, first slide rails are arranged on one side of the mold B and extend in the axial direction, first slider pieces are fixedly mounted on the mold B, and the first core-pulling slider can outwards slide out of the mold along the first slide rails; and second slide rails are arranged on the opposite side of the mold B and extend in the axial direction, second slide rail parts are fixedly mounted on the mold B, and the second core-pulling slider can outwards slide out of the mold along the second slide rails. The mold is used for injection molding of the large-size uniparted hyperboloid injection molding part, the problem about coaxiality of the core-pulling sliders and the injection molding part when the core-pulling sliders perform core pulling can be effectively solved, and the injection molding quality of products is guaranteed.

Description

technical field [0001] The invention relates to the field of mold technology, in particular to a mold for a large-volume single-leaf hyperboloid injection molded part. Background technique [0002] With the wide application of plastic products, in the production process of plastic products, people often require the production of beautiful and practical products with curvature and curvature, such as horn-shaped, single-leaf hyperboloid, and scabbard-shaped hollow structural parts, etc. . [0003] For single-leaf hyperboloid injection molded parts, the hollow structure needs to be core-pulled from two opposite directions during the overall injection molding. When core-pulling, in order to ensure the quality of the injection molded part, the two Coaxiality has higher requirements. Especially for larger single-leaf hyperboloid injection molded parts, the injection molding difficulty is higher. Due to the larger volume of the core-pulling slider, it is difficult for the core-pu...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the invention is to avoid the above-mentioned shortcomings in the prior art and provide a mold suitable for large-volume single-leaf hyperboloid injection molded parts, so as to solve the coaxial problem of the core-pulling slider and the injection molded part when pulling the core. To ensure the quality of production
