Description

Technical Field

[0001] The utility model relates to the technical field of metal tube shell glass packaging, in particular to a horseshoe-shaped glass and metal sealing mold. Background Art

[0002] Metallic glass, also known as amorphous alloy, has the advantages of both metal and glass, while overcoming their respective disadvantages, such as glass being fragile and having no ductility. The strength of metallic glass is higher than that of steel, its hardness exceeds that of high-hardness tool steel, and it has certain toughness and rigidity.

[0003] Reference patent publication number "CN207130160U" discloses a metal glass sealing mold, including a shell and a base with a shell placement area at the upper end, a fixed block placement groove is opened on the base, a shell fixing block is placed in the fixed block placement groove, a conical groove is provided at the bottom of the shell placement area, a core column placement hole is provided at the lower end of the conical groove, and a core column positioning block is placed in the conical groove.

[0004] This patent can reduce the sealing stress. In the traditional horseshoe insulator and metal sealing, the widely used method is to use a split mold to position from the inner cavity and the outer side of the shell respectively, and then use a clamp to fix the mold to achieve the positioning effect. This will cause errors in the positioning of the inner and outer molds. When the lead enters the high-temperature sintering furnace, as the temperature continues to rise, the insulator melts into liquid. Under the error of the inner and outer molds, the directions of expansion and contraction are asymmetric, causing the lead to be eccentric, and it is also easy to cause the lead to deflect upward. If the lead is to be restored to a horizontal level, it is necessary to reshape the lead. There is also a risk of cracking of the insulator during the subsequent reshaping process. At the same time, due to Due to the error of the mold itself, the gap with the tube shell is unstable, the amount of insulators is difficult to control, and the quality of the final molded shell fluctuates greatly. When the matching gap between the lead and the mold is too small, there will inevitably be interference between them, causing the lead to deform and bend, and eventually an eccentric short circuit will occur, affecting the electrical performance of the shell. When the matching gap between the lead and the mold is too large, although there will be no interference between them due to the difference in expansion coefficients, another problem will arise, that is, the length size and accuracy of the lead in the shell cannot be guaranteed. This is a common problem in the field of metal shell packaging, that is, the axial size of the lead fluctuates greatly. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-Figure 4 The horseshoe-shaped glass-to-metal sealing mold provides two technical solutions:

[0023] The first embodiment comprises a graphite mold 1, a metal shell 2 and a graphite clamp 3, wherein the graphite mold 1 is invertedly sleeved in the middle of the graphite mold 1, and two graphite clamps 3 are respectively clamped on the left and right sides of the top of the graphite mold 1, and the inside of the graphite mold 1 is provided with two left and right deep grooves 11 for inverted insertion of the metal shell 2, and the top of the graphite mold 1 is provided with two left and right glass insulator avoidance holes 14, and the inside of the graphite mold 1 is provided with two left and right lead holes 13, and the two lead holes 13 are respectively connected to the two glass insulator avoidance holes 14. The hole 14 is connected, and two left and right air avoidance structures 12 are also opened inside the graphite mold 1, and the deep groove 11, the air avoidance structure 12 and the lead hole 13 are in a connected state. The top of the metal shell 2 is provided with two left and right horseshoe glass insulator grooves 21, and the bottom of the inner wall of the horseshoe glass insulator groove 21 is provided with a lead through groove. The graphite card mold 3 is U-shaped as a whole, and a left and right through lead pressing groove 31 is opened in the middle position inside the graphite mold 1, and the left and right sides of the two graphite card molds 3 are fixedly connected with two left and right pressure plates 32.

[0024] By modifying the mold layout, the dimensional fluctuation caused by the mold can be reduced. The position of the lead can be determined by constraining the lead in the three directions of length, width and height. By positioning the lead in the three circumferential directions of X, Y and Z, the dimensional fluctuation is reduced.

[0025] The second embodiment is mainly different from the first embodiment in that: the front and back sides of the graphite mold 1 are both provided with left and right clamping assemblies 4 for enhancing the stability of the mold, the clamping assembly 4 includes a slide block 41, and the slide block 41 is fixedly connected to the front side of the graphite mold 1, a slide rod 42 is fixedly connected between the top and bottom of the inner wall of the slide block 41, a slider 43 is slidably connected to the surface of the slide rod 42, a limiting spring 44 is fixedly connected between the top of the inner wall of the slide block 41 and the top of the slider 43, a T-bar 45 is fixedly connected to the front side of the slider 43, a hook 46 is rotatably connected to the surface of the T-bar 45, and a hanging rod 47 for cooperating with the hook 46 is fixedly connected to the front side of the graphite mold 1.

[0026] After the two graphite clamps 3 are placed on the graphite mold 1, the positions of the two graphite clamps 3 are positioned and clamped by the clamping assembly 4, thereby ensuring the stability of the structure of the mold when it is used.

[0027] When in use, put the metal shell 2 upside down into the graphite mold 1, make sure that the graphite mold 1 is completely pressed down without leaving any gaps, then put the glass insulator into the horseshoe glass insulator groove 21, then insert the lead wire into the glass insulator, and put the outer side into the lead wire groove 15 of the graphite mold 1, the glass insulator and the lead wire groove 15 will limit the horizontal displacement of the lead wire, forming a constraint on the lead wire, then press the graphite card mold 3 on the lead wire groove, the gravity of the graphite card mold 3 will limit the deflection of the lead wire in the vertical direction, To prevent the lead from deflecting upward, the hook 46 is then rotated and lifted up so that the hook 46 is hung on the hanging rod 47. The hook 46 is pressed on the hanging rod 47 by the action of the limit spring 44. At this time, the graphite clamp 3 is fixed, and then the glass insulator is placed in the horseshoe glass insulator groove 21. By designing the gap between the clamp 3 and the metal shell 2, the glass insulator can be just placed in the horseshoe glass insulator groove 21 without protruding, thereby preventing the glass insulator from climbing up. Finally, the metal shell 2 is sent to the sintering furnace for sealing.
