一般筆記型電腦的外殼中，有一種利用金屬材質的外 殼因為具有良好的質感，所以受到消費者的喜愛，但是金 屬材質的外殼的側面卻不容易加工出複雜結合、卡掣或定 位等結構，若直接在金屬材質的外殼上加工製作，既費時 又耗成本。In the outer casing of a general notebook computer, there is a metal casing that is favored by consumers because of its good texture, but the side of the metal casing is not easy to process complex structures, cassettes or positioning structures. It is time consuming and costly to process directly on a metal casing.

The main purpose of the embedded molding method of the casing of the present invention is to use the plastic two = let the r agent soften 'to make the plastic and the adhesive adhere to form a plastic layer fault to return the product yield and effectively shorten the process. A secondary object of the method of insert molding of the casing of the present invention is to dilute the diluent with a diluent to coat the metal appearance member. Another advantage of the method for insert molding of the casing of the present invention is that, in the twisting process, the heating causes the diluent to volatilize and the adhesive-curing (four) to be combined with the metal appearance member. Other objects, advantages, and novel features of the present invention will become more apparent from the following detailed description. [Embodiment] The technology, the means and the functions thereof used in the present invention are as follows - compared with the preferred embodiment of the present invention and the detailed description of the drawings, the description is for illustrative purposes only, and is not limited in patent application. The limitations of this structure. Referring to the drawings -' is a manufacturing flow chart of the present invention. The embedded molding method of the casing of the present invention comprises the following steps: preparing a metal appearance component; applying an adhesive on the inner surface of the metal appearance component; heating the metal appearance component coated with the adhesive to bond the adhesive to the metal appearance component 1. A metal appearance part is placed into a plastic injection molding mold, and a hot melted plastic is injection molded on the cured adhesive of the metal appearance member, and the temperature of the hot melted plastic is softened, thereby making the adhesive soften, thereby After the plastic and the adhesive are combined, the cured plastic forms a plastic layer on the metal appearance member; / the finished metal appearance member is taken out. Referring to Fig. 2 and Fig. 3, the metal The inner side of the appearance member 10 is concave, and the outer surface of the metal appearance member 10 is the outer surface of the casing. The inner surface of the metal appearance member 10 can be injection molded into a complicated combination, a cardinal or a position. «The outer edge of the inner surface of the appearance member 10 is coated with an adhesive, and the adhesive 20 is first mixed with the diluent and then applied to the metal appearance member 10. The adhesive 20 is viscous and is easily applied to the inner side surface of the metal appearance member, wherein the adhesive 20 is a polyurethane (PU) copolymer and the diluent is methyl ketone (METHYL ETHYL KETONE, ΜΕΚ). The polyurethane copolymer needs to be added with Ding Ding to make the adhesive 20 viscous and has a viscosity of 201105204 at room temperature, while the adhesive 2 viscous agent can be applied to the coating of the metal appearance. : Referring to Figure 4, the metal appearance member (7) coated with the adhesive 2 () is set to "°", and the ▲ is set to 30 to heat the material, and the heating device is 55-65 ^ * sr rr ^ ) heating / dish degree in the ... The temperature is such that the diluent of butanone in the adhesive 20 is volatilized, and at the same time, the adhesive which solidifies and solidifies the metal part is cured.

The second mold 42 is provided with a molding portion 相对 relative to the outer edge of the accommodating groove 411, and the 421 is corresponding to the metal appearance. 1 〇 of the adhesive 2 〇. The male mold is similar to a rubber passage 422 and two demolding portions. The rubber passage 422 is connected to the '1 M21 to cause the plastic to be ejected from the molding portion 421, and the demolding portion can extend beyond the molding portion 421. The outer surface. In the step of injection molding, the metal appearance member 1A of the adhesive 2〇 is placed in the receiving groove 411 of the mold base 41, and then the male mold 42 is clamped with the mold base 41, and the molding portion of the male mold 42 is formed. 421 corresponds to the bonding of the metal appearance member 1 j, and the hot squeezing plastic is injected through the rubber channel 422 of the male mold 42 on the adhesive 2 of the metal appearance member 1 And the temperature after the injection of the plastic A can soften the fixed adhesive 2 〇 opposite to the one side of the metal appearance member 10, and the softened adhesive 2 〇 can be combined with the plastic A. Therefore, while the hot-melted plastic A is ejected After the adhesive 2〇 is combined with the plastic 201105204 A, the plastic A is cured to form a plastic layer 5〇, and the demolding portion seems to be bonded to the plastic layer 50. The adhesive 2 is combined with the metal appearance member ι and the plastic. Layer 50. The plastic a is a thermoplastic plastic (Therm〇Piastlc), and the plastic A is emitted at a temperature of 160 to 250 degrees. Referring to FIGS. 7-9, when the male mold 42 is separated from the mold base 41, the metal appearance member 10 is moved up with the mold release portion 423 and separated from the mold base 41, and then the mold release portion 423 lowers the metal appearance member 1G. After the exit, the cut off portion is removed from the joint of the plastic layer 50 to obtain a finished metal part. The plastic injection molding of the invention is carried out on the same day as the metal appearance member 1 adhesive, and the adhesive is softened by the temperature of the plastic injection, so that the plastic and the adhesive 2 are bonded together and then solidified to form a plastic layer 5, which is shot by the plastic A. Straight ^ combined with the adhesive 20, it is not easy to produce positional errors to improve product yield, and effectively shorten the process and reduce production costs. The embedded forming technology of the present invention comprises the following steps: preparing a metal appearance member - coating the inner surface of the metal appearance member with a coating, heating the metal appearance member of the coating agent to heat the adhesive and bonding the metal appearance member Together - the metal appearance parts are placed - plastic injection molding die = melted plastic injection molding on the solidified adhesive of the metal appearance parts ^ = the temperature of the returning mixed green, the turntable turn ttr, and After the combination of the plastic enamel agent and the curing, the cured _ Γ Γ formation - plastic layer ^ metal appearance of the finished product is taken out to hunch the product yield and effectively shorten the process. As far as the above is concerned, it can be concluded that the present invention has the following advantages: 201105204 ι·本 翻 "the casing is embedded into the wealth method", and the (four) agent is softened by the (four) glue to make the combination of the plastic and the adhesive form a layer. In order to improve product yield and effectively shorten the process. 2. The "enclosure-incorporated method" of the present invention is carried out by adding a diluent to the adhesive-coated step adhesive to make the adhesive easy to coat on the metal-like appearance. 3: The invention discloses a method for inserting a casing into a body. In the heating step, the thinner diluent volatilizes and the adhesive is solidified, so that the adhesive and the metal appearance and the standard are only the present invention. The preferred embodiment is not limited to the scope of the present invention, so any change in the value or equivalent replacement or equivalent change according to the scope of the patent application of the present invention should still be covered by the patent of the present invention.
