Description of the Invention: [Technical Field of the Invention] A method for injection molding. The present invention particularly relates to a product which is capable of producing a large thickness and a multi-color combination in the same process by using a plurality of injection molding machines. Injection molding method. [Prior Art] Plastic materials are widely used in the industry and have a wide range of uses. They are mainly used in many good properties such as light weight, high financial efficiency, low cost, easy processing and high mechanical strength. Among various industrial products. The method of plastic processing and molding varies according to the needs of various products, and the most commonly used processing method in the industry is injection molding, because this processing method is suitable for mass production, complicated shape, accurate size and price. The lower product can be fully automated in the process of manufacturing. The choice of traditional injection molding processing conditions in the past relies on the past experience of the practitioners. In many attempts, the mold design and processing conditions are improved. This method is not only time-consuming and labor-intensive. It is necessary to have the accumulation and inheritance of technology. In the production process of high-thickness finished products, the residual stress caused by heat often appears in the cooling stage, and when the polymer cools, it begins to shrink and the degree of shrinkage The orientation of the molecules is related to the residual stress if the cooling rates on both sides of the mold wall are different. This unbalanced cooling will cause asymmetric elongation and compression force in the finished product, which will cause bending moment and cause warpage of the finished product. Therefore, the general injection molding method is not suitable for directly making a high-thickness system 201130633 It is usually achieved by other methods, such as first casting a thin semi-finished product, then passing it through (secondary processing), or injecting a large-volume semi-finished product, and then cutting it. The above-mentioned types of processing methods cause problems such as lengthening of the process, different processing quality, and increased human resource costs. Please refer to "Figure 1" and "Figure 2". These two drawings are the front and back of a finished product. Please refer to the figure as a finished product of 1咼 thickness (thickness dl). ), if you want to enter the lamp in the traditional way, it is bound to be pre-formed by infusion [re-cutting two-person processing, and further, this finished product is composed of two colors, including a frame When the part 1G1 and the inner frame part 1Q2 are processed in a conventional manner, the process is more difficult, and it may be further required to perform a multi-stage milling machine. SUMMARY OF THE INVENTION In view of the above problems, the present inventors have conducted relevant research and analysis on the requirements of injection molding processes and high-thickness finished products based on years of experience in related industries, and can develop more. The appropriate process 'to improve the production efficiency of the finished product of the thickness; therefore, the main object of the present invention is to provide an injection molding method capable of completing the finished product of the thickness in the same manufacturing process. According to the injection molding method of the present invention, a plurality of injection molding machines are mainly used, and in the injection molding process, the first injection molding machine first performs the injection molding operation at the first thickness portion, and after the injection molding is completed, the 201130633 is completed. , that is, the semi-finished product is moved to the second injection molding machine, and the second thick-production partial injection molding operation is performed, and (4) when the __th thickness portion is injection-molded, the material of the semi-finished product is still in an incompletely cured state, and is immediately performed. The second thickness injection molding operation makes the thickness of the semi-finished product reach the thickness of the finished product, and accordingly, since the adhesive property and the molecular compatibility of the rubber compound in the molten state are optimal, the combination of the injection molded product is produced. The degree of optimum bonding can be achieved, and the requirements for high-thickness finished products can also be achieved.

Providing a high-thickness and multi-color to the first-thickness portion in a process, and forming at least a positioning portion: in a first-injection molding machine, in the mold, the injection-formed-thickness portion is formed The end edge of the first-thickness portion is formed with at least a positioning portion; the rotary mold is transferred to the second thickness forming portion of the second injection molding machine; the second thickness portion is injected, and the first thickness portion is completed Fusion: by the first injection molding machine - the second thickness portion is emitted, and the first thickness portion ' after the injection is merged with the first thickness portion to form 13 201130633 type machine conversion mold: the hole is completed The semi-finished product is transferred to the third portion to emit the third thickness portion, and is integrated with the first thickness portion: the third thickness portion after the third thickness portion of the different color is emitted by the second injection molding machine, and the The first-thickness part completes the fusion; the transfer mold··the semi-finished product completed by the drilling is transferred to the first type machine; the fourth thickness part is injected, and the thickness part is finished: the fourth injection molding machine enters - fourth thickness portion is emitted, the thickness of the fourth portion of the emitted 'each coated on the thickness of other parts of dazzle and complete melting of the two to form integrally manufactured; release: cooling after finished curing the mold prolapse. 14 I
