Background

In the fields of aviation, aerospace, ships, electronics, communication, radar weapons and the like, some high-end electronic devices such as microelectronics, connectors, sensors and the like are widely applied. Since the chips in these precision electronic products are not protected from various external factors to cause their accelerated failure, some stainless steel glass package packages with specific functions are needed to provide connection and support for these electronic devices. The stainless steel glass packaging tube shell connects the internal chip with external equipment to serve as a data exchange medium of the electronic equipment to provide guarantee for the electronic equipment. In the design process of the product, the stainless steel packaging product is required to meet the requirements of oxidation resistance and corrosion resistance under specific conditions. However, because the expansion coefficient of the stainless steel product is far greater than that of the graphite mold, the problems of poor concentricity of the lead, poor position consistency, poor flatness of the glass surface and the like in the sintering process of the stainless steel product are core points influencing the quality of the finished product.

Furthermore, the lower positioning fixture is provided with three two-hole short graphite pipes and five one-hole short graphite pipes, and the upper positioning fixture is provided with three upper positioning graphite columns and six one-hole feldspar ink pipes.

Furthermore, a hole feldspar ink tube on the upper positioning fixture is arranged in a through hole with the diameter of 2.0mm, two upper positioning graphite columns are arranged in the through hole with the diameter of 3.5mm, and one upper positioning graphite column is arranged in the through hole with the diameter of 3 mm.

Furthermore, five short graphite tubes with one hole on the lower positioning clamp are arranged in blind holes with the diameter of 2mm, two short graphite tubes with two holes are arranged in the blind holes with the diameter of 3.5mm, two through holes with the diameter of 0.65mm are arranged at the bottoms of the blind holes, one short graphite tube with two holes is arranged in the blind hole with the diameter of 3mm, and two through holes with the diameter of 0.4mm are arranged in the blind holes.

Furthermore, a step hole with the diameter of 15.3 mm and the diameter of 13mm is formed in the position of the positioning bottom plate, a boss with the diameter of 7mm is arranged in the center of the positioning bottom plate, and a through hole with the diameter of 3mm is formed in the edge of the boss.

The utility model has the advantages that:

the utility model relates to a nonrust steel pipe shell glass package mold, the location form of positioning fixture under positioning fixture, the stainless steel on the stainless steel, effectively solved the coefficient of expansion difference and leaded to the problem of lead wire position degree deviation, the shell can be guaranteed to expand with huge concave huge synchronous at high temperature down with the same material of anchor clamps with the anchor clamps, and the relative position of lead wire does not produce the change. The graphite column embedded mode can avoid direct contact between the glass insulator and a non-sealing area, and avoid the phenomenon that the glass insulator overflows to other areas of the tube shell. The feldspar ink tube with the steps reduces the contact between graphite and the glass insulator as much as possible, and avoids the phenomenon that graphite powder is adhered to the surface of the glass insulator. Meanwhile, the graphite column is beneficial to the phenomena of difficult demoulding of the multi-lead clamp and cracking of the glass insulator caused in the demoulding process. Greatly improving the quality of the product and the production efficiency.
