Embodiment Construction

[0023] In order to make the above-mentioned technical scheme of the present invention and its advantages clearer and easier to understand, the preferred solution is enumerated below and described in detail as follows:

[0024] see attached image figure 1 A to Figure 3B As shown, the present invention provides an injection molding method, which can be applied to integral injection molding of two or more raw materials.

[0025] One of the embodiments of the present invention is to manufacture the notebook computer case 10, because the notebook computer case body 11 is a plastic material, and the sealing layer 12 formed on the notebook computer case body 11 is a rubber material, this just needs two different materials to be integrally injected Forming, the main manufacturing methods are as follows:

[0026] (1) First provide an injection molding machine equipped with two injection molding devices, namely, injection molding rubber tubes A and B, and a rotary table C, wherei...

Abstract

The invention provides an integrating injection moulding method. Injection moulding equipment for injection moulding of two different raw materials is arranged on a revolving stage of an injection machine; then a first injection moulding is carried out in a first injection mould, namely one injection moulding apparatus is utilized to fill a first raw material into the first injection mould, so as to form a semi-finished product; then rotation of a revolving stage is employed to enable the first injection mould together with the semi-finished product thereon to change position with a second injection mould; then a second injection moulding is carried out that a second injection moulding apparatus is utilized to inject a second raw material into a mould cavity containing the semi-finished product, so as to form a product. Meanwhile, a first injection moulding is carried out in another mould cavity to form a semi-finished product; the finished product is taken out; and the above operations are repeated for continuous production. The method can not only increase product performance and qualified rate but also improve product quality.

Description

[0001] technical field [0002] The invention relates to an injection molding method, in particular to an integrated injection molding method adopting a combination of multiple materials, belonging to the field of injection molding of plastic products. Background technique [0003] With the continuous development of injection molding methods, many products often need to be integrally injection-molded with a variety of materials of different materials and / or colors during processing. For example, the color shell of the mobile phone, the shell of the notebook computer, etc. [0004] The existing method of integral injection molding of two different materials and / or colors is usually to inject one material and / or color on one injection molding machine, and then transfer the semi-finished product to another Injection molding of another material and / or color on the injection molding machine. With this traditional method, a large clamping force is required in the process of tran...
