Description

Thermoplastic one-piece metal shell implant fitting method

The metal shell embedding and laminating method of the thermoplastic integrated molding of the invention is mainly applied to the molding technology of the metal shell embedding and laminating plastic which is integrally formed by 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 will also erode metal and plastic, which is a problem and a deficiency that has yet to be solved.

The present inventor is currently engaged in the manufacture and design of related products, accumulating practical experience and experience for many years, and actively investing in the spirit of innovation and improvement in order to solve the existing problems and lack of traditional metal shell embedded plastics. One-piece metal shell implant fitting method.

The technical means applied to solve the problem and the effect of the prior art are as follows: the metal plate is first placed in the lower die, the ring is surrounded by a ring-shaped groove, and the spacer is placed in the groove, and the top surface of the spacer is high. Out of the die plane, the metal plate is first placed in isolation The top surface of the gasket is pressed, and the upper mold is pressed downward to apply a certain pressure to the metal sheet. The lower mold and the upper mold are heated to a proper temperature by a heating device to deform the molding, and then the pressure of the high pressure gas is input from the upper mold. The molded plastic material is blown up and down into the cavity, and after the molding, the separator is not adhered to the cavity due to the isolation of the isolation gasket, and the excess portion is cut off after the finished product is taken out. That is, an integrally formed metal shell product is obtained, and a through hole having the same pitch is disposed in the groove of the metal shell, and the finished metal shell is processed by an anode, and then the inner layer is required to be etched or laser-engraved, and The metal shell inner layer etching treatment or laser engraving processing is used for sizing, the plastic inner mold is placed in the metal shell finished product and combined with the hot sol, and the squeegee is coated in the groove, and then the plastic slab is embossed. The pin is inserted into the through hole in the groove, so as to combine with the hole corresponding to the plastic inner mold, and the tail end of the combined post pin is slightly higher than the plane of the plastic inner mold, and then the heated mold is connected to the convex column. Pressing the end of the foot to make it fit with the plastic inner mold Synthetic one; not only the production of low cost, but also improve the precision machining, can effectively avoid defective, with enhance the effectiveness and reach of which the main purpose.
