Injection mold for fixed mold sliding block of mobile phone rear cover

Abstract

The invention relates to an injection mold for a fixed mold sliding block of a mobile phone rear cover. The injection mold comprises a fixed mold body, fixed mold forming mechanisms arranged on the side faces of the fixed mold body and a movable mold matched with the fixed mold body; the fixed mold forming mechanisms are arranged on the left side and the right side of the fixed mold body correspondingly; the fixed mold forming mechanisms comprise locking blocks, T-shaped sliding-guiding blocks, inclined sliding blocks, pressing plates and side mold cores; the side mold cores are arranged in the fixed mold body, the pressing plates are arranged on the side mold cores, and the inclined sliding blocks are arranged on the pressing plates to be matched with the pressing plates; the inclined sliding blocks are provided with guiding rails, and T-shaped sliding blocks are arranged in the guiding rails to be connected with the inclined sliding blocks in a sliding fit mode; and the end faces ofthe inclined sliding blocks are connected with the end faces of the locking blocks in a sliding fit mode. The injection mold is formed through fixed mold sliding block core-pulling mechanisms, side mold cores and sliding blocks of the fixed mold sliding block core-pulling mechanisms are mounted on a front mold, contact between plastic parts and the sliding blocks is avoided, and thus the injectiontraces are not left on the surfaces of the plastic parts; and the high appearance requirements that the injection traces cannot exist on the surfaces of formed products is ensured, and the forming effect is good.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an injection mold for fixed mold sliders of mobile phone back covers. Background technique [0002] With the prosperity of the market economy, the application of injection molds is becoming more and more extensive, and the market demand is gradually increasing. Injection molds have a better development prospect, and the requirements for the quality of injection molds are also stricter. At present, injection molds are gradually developing in the direction of multi-function, high precision and automation. Injection molding machine and injection mold are the most important equipment in the injection molding process, and the core module in the injection molding process is the injection mold, and the design of various process parameters in the injection molding directly determines the production cycle and quality of the process. [0003] In the mobile phone back cover molding...

AI Technical Summary

Problems solved by technology

[0003] In the mobile phone back cover molding process, the molded product has the following requirements: 1. There should be no injection marks on the surface of the molded product; 2. The molded product has a certain mechanical strength, roughness and assembly accuracy; however, the existing injection molds use dynamic Mold slider core-pulling mechanism and submerged thimble gate, such a mold cannot meet the process requirements of the molded product
