Embodiment 1

[0031] see figure 1 As shown, it depicts a flow chart of the steps of a preferred embodiment of the manufacturing method of the strong casing of the present invention. In this embodiment 1, the manufacturing method of the strong casing of the present invention includes the following steps:

[0032] Step 101: Injecting high-rigidity plastic material into a structural part in a single-color machine injection mold.

[0033] Step 102: Embedding the structural part into another single-color machine injection mold with the RHCM system, and injecting soft rubber micro-foaming molding on the structural part. The micro-foaming process of the soft rubber is to first pass nitrogen or carbon dioxide through the supercritical fluid control system to generate a supercritical fluid, and then output it to the injection interface, and inject it into the stirring zone of the screw of the injection molding machine through the injection interface, and the molten soft Glue and supercritical flui...

Embodiment 2

[0036] In this embodiment 2, the manufacturing method of the strong casing of the present invention includes the following steps:

[0037] Step 201: In a two-component injection mold equipped with an RHCM system, inject a high-rigidity plastic material micro-foamed structural part. The process of the micro-foamed structural part is to first generate nitrogen or carbon dioxide through a supercritical fluid control system The supercritical fluid is output to the injection interface, and then injected into the stirring zone of the screw of the injection molding machine through the injection interface. The molten high-rigidity plastic material and the supercritical fluid are fully dissolved in the stirring zone to form a single-phase solution, and at a certain constant Keeping it under pressure, when the injection molding machine issues an injection command, the switch nozzle will open and inject the single-phase solution into the cavity of the two-component injection mold with RHC...

Embodiment 3

[0041] Step 301: Injection-molding the micro-foamed structural parts of high-rigidity plastic materials in a single-color machine injection mold with RHCM system, the same principle, the micro-foamed molding method is as described above;

[0042] Step 302: Embedding the structural part into another single-color machine injection mold, and injecting soft rubber on the structural part.

[0043] Therefore, when injecting high-rigidity plastic materials, RHCM combined with micro-foaming molding is used for injection molding to obtain an appearance without air marks, which can be used directly as appearance parts, and the obtained products are both light and strong, and beautiful in appearance. Through the overall structural design , The overall weight of the product can be reduced by 20-30%.

Abstract

The invention provides a method for making a strong shell and its products. The method includes the following steps: molding structural parts with high-rigidity plastic materials; molding products with soft rubber on the structural parts; wherein, the high-rigidity plastic materials, soft rubber At least one of them is injection-molded by RHCM combined with micro-foaming molding. The product is a product produced by the above-mentioned strong shell manufacturing method. The manufacturing method of the strong shell of the present invention can solve the problem of gas streamlines on the appearance of the existing micro-foaming products by adopting the combination of the RHCM molding method and the micro-foaming molding method to form products, and obtain lightweight products.

Description

[0001] 【Technical field】 [0002] The invention relates to a manufacturing method of a strong shell and its products, in particular to a manufacturing method of a strong shell applied to a strong equipment and its products. [0003] 【Background technique】 [0004] With people's increasing pursuit of high quality of life, people's pursuit of products is also paying more and more attention to its shape and appearance decoration effect, and the development of products in some special industries is increasingly demanding light and thin, high rigidity and toughness at the same time. . For example, the development trend of military specification computer products is towards thinner, lighter and stronger. [0005] Precision injection molding technology has attracted more and more people's attention, for example, high and low temperature plastic molding technology, micro foam molding technology, etc. Among them, high-low temperature plastic molding technology (RHCM: Rapid Heat Cycle ...
