Description

Thermoplastic one-piece metal shell embedding device

The metal shell embedding device of the invention is mainly used for forming the metal shell embedded plastic of thermoplastic molding.

According to the traditional metal shell, it is not formed in one piece, but is divided into several pieces and then combined into one. At the same time, the traditional method of embedding the plastic in the metal shell is mainly to first process the metal shell rough embryo through the CNC. After the anode treatment, the metal shell is taken out to shoot the plastic, which is not only expensive to manufacture, but also wears after a period of time, causing the machining tolerance to increase in tolerance, resulting in defective products. At the same time, the anodized chemical also erodes the metal and the plastic; moreover, when the plastic is shot, the plastic is easily raised from the metal shell, and the hand is touched, and the touch is not good. Problems and lacks to be solved.

The creator is currently engaged in the manufacture and design of related products, accumulated many years of practical experience and experience, and has actively invested in the spirit of innovation and improvement in response to the existing problems and lacks of traditional metal shell embedded plastics. One-piece metal shell embedding device.

The technical means applied by the new problem solving and the effect of the prior art are as follows: the thermoplastic molded one-piece metal shell finished through the anode, and the grooved arc surface in the metal shell is insulated by CNC machining, and then the inner layer is Etching or laser engraving at the required location Processing, and sizing in the inner layer etching process or laser engraving processing of the metal shell, the through holes of the same spacing are reserved in the grooves of the metal shell, and the sides of the groove are processed into a micro plane, which is set on the plane An arc-shaped mold having the same shape as the metal shell, the two sides of the curved mold are slightly larger than the two sides of the groove, and a spring is placed behind the mold, and when the injection molding is performed, the plastic is merged to the through hole reserved by the metal shell, and the outer hole is outward through the groove The effluent and the embedded thermoplastic are integrally formed, and when the plastic touches the curved mold, the plastic is pushed outward. At this time, the elastic shape of the curved mold is restricted by the elasticity of the rear spring, thereby achieving the plastic overflow tolerance. Within the acceptable range, the hand is touched, the touch is excellent, and the effect is improved, which is the main purpose.

In order to make it easier for those who are familiar with the art to understand the construction content of the creation and the functional benefits that can be achieved, a specific embodiment will be listed, and the detailed description will be given as follows: a thermoplastic molding Metal shell embedding device, please refer to the first figure to the first The five figures are shown. The utility model mainly comprises: a metal shell 10 and a plastic 20; wherein: the surface of the metal shell 10 of the thermoplastic integrally formed is provided with two grooves 11 above and below the surface of the metal shell 10, and the metal shell 10 protrudes from the inner surface of the two grooves 11 to form two arcs. After the surface of the metal shell 10 is processed through the anode, it is insulated by CNC machining on the two curved surfaces 111 of the metal shell 10, and the inner layer is processed by etching or laser engraving at the position of the inner layer, and the metal shell 10 is processed. The inner layer etching process or the laser engraving processing portion 112 is smeared 113, and a plurality of through holes 12 having the same pitch are reserved in the two grooves 11, and the two corners of the groove 11 are processed into a minute plane 13 and An arc-shaped mold 14 having the same outer shape as that of the metal shell 10 is disposed on the flat surface 13, and both sides of the curved mold 14 are slightly larger than both sides of the groove 11, while a spring S is placed behind the curved mold 14, and plastic is formed during injection molding. 20, the through hole 12 which is reserved to the metal shell 10, flows outward through the groove 11 (as shown in the first figure), and is pushed outward when the plastic 20 touches the curved mold 14, and the curved mold 14 is now pushed. By the elasticity of the rear spring S, the plastic 20 can be pushed outwardly to be limited, thereby controlling The allowable amount of plastic 20 overflow is within an acceptable range (as shown in the second figure). After injection molding, two plastics 20 can be integrally formed in the groove 11 above the metal shell 10 (such as the third and fourth The figure of the plastic 20 can be selected from plastics.

In summary, the present invention provides a thermoplastic integrated molded metal shell embedding device. After the actual fabrication and repeated operation tests of the creator, it is confirmed that the functional benefits expected by the creation can be achieved. For the first time in the world, there is no such thing as the creation of the industry, and it has the industrial use value. It has already met the important requirements of the practicability and progress of the new patent, and has filed a new patent application with the bureau.
