Problems solved by technology

Injection molding needs to make injection molds. The traditional middle frame proofing method needs to make an injection mold according to each sample, which will not only prolong the research and development cycle, but also lead to a significant increase in the development cost of injection molds.

Embodiment Construction

[0042] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0043] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as c...

Abstract

The invention relates to a middle frame proofing method. The method comprises the following steps of providing a plate; conducting CNC machining on the plate, and forming an injection molding structure and an injection molding runner on the front face and the back face of the plate; enabling the injection molding runner to communicate with the injection molding structure; using areas, outside theinjection molding runner and the injection molding structure, of the front and back faces of the plate as glue sealing surfaces; placing the plate in an injection mold for injection molding, enablingthe injection mold to be tightly attached to the glue sealing surfaces, guiding plastic materials to the injection molding structure through the injection molding runner, and forming an attached plastic part at the injection molding runner and the injection molding structure; and carrying out CNC machining on the plate and the plastic part to obtain a formed middle frame. According to the middle frame proofing method, after the plate is selected, the injection mold does not need to be structurally adjusted according to the style of the middle frame, so that universal use and rapid proofing ofthe injection mold are achieved, the research and development period can be shortened, and the development cost of the injection mold can be reduced.

Description

technical field [0001] The invention relates to the technical field of electronic product manufacturing, in particular to a middle frame proofing method. Background technique [0002] With the development of touch screen technology, most electronic products now use touch screens as display screens and input tools. Therefore, the structural design of electronic products has gradually changed to a combination of a touch screen, a middle frame, and a bottom cover. Among them, the middle frame is the main carrier of electronic parts, such as control circuit board, control chip, antenna, battery, data input terminal, and other electronic parts, etc. are installed on the middle frame. [0003] In the product development stage, it is necessary to proof the product design plan, test the samples obtained from proofing, and enter the mass production stage after the test is passed. Therefore, multiple product proofings may be required before the final design of the product is determi...
