[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0017] Please see Figure 1-4This utility model provides an embodiment of a sintering mold, including a holding crucible 8. The holding crucible 8 has six placement chambers 801 evenly distributed inside. Zirconium beads 9 are arranged inside each placement chamber 801. Six positioning blocks 802 are arranged at the upper end of the holding crucible 8, symmetrical about the vertical center line of the holding crucible 8. The positioning blocks 802 and the holding crucible 8 are integrally formed. A support base 803 is provided at the lower end of the holding crucible 8. A through groove 805 is provided on one side of the support base 803. The placement chambers 801 allow for the placement of sintered items, and the zirconium beads 9 provide support, thus preventing adhesion between the sintered items and the holding crucible 8. It should be noted that, to save space and highlight the innovative elements of this patent, such as the specific working principle and process of the sintering mold, will not be elaborated upon in this patent.

[0018] See Figure 3 and Figure 4 There are four support bases 803, which are arranged sequentially at the lower end of the crucible 8. The support bases 803 and the crucible 8 are an integral structure. The lower end of the support base 803 is provided with a positioning groove 804. The positioning groove 804 is correspondingly set with the positioning block 802. The support bases 803 can support and place the crucible 8.

[0019] A pre-sintering furnace 1 includes an installation chamber 101 inside, with refractory bricks 2 installed inside the installation chamber 101. A support box 102 is located at the lower end of the pre-sintering furnace 1, and a control panel 103 is located at the front end of the support box 102. A sealing door 5 is installed on one side of the pre-sintering furnace 1, with heat insulation cotton 501 lining the inner wall of the sealing door 5. A sealing seat 6 is installed on one side of the sealing door 5, and refractory bricks 7 are installed on one side of the sealing seat 6. A support frame is located at the lower end of the installation chamber 101. A silicon carbide heating rod 3 is installed above the mounting chamber 101 on the support 4. The crucible 8 is located above the support 4. The pre-sintering furnace 1 is supported by the support box 102 and sealed by the sealing door 5, which improves the performance of the pre-sintering furnace 1. The silicon carbide heating rod 3 heats the inside of the pre-sintering furnace 1. The heat resistance of the pre-sintering furnace 1 is improved by refractory brick 1 2 and refractory brick 2 7, which makes the service life of the pre-sintering furnace 1 longer.

[0020] See Figure 1 and Figure 2The heat insulation cotton 501 is connected to the sealing door 5 by adhesive. The sealing seat 6 is set corresponding to the front end of the installation chamber 101. Several support placement seats 4 are arranged in sequence at the lower end of the installation chamber 101. Several silicon carbide heating rods 3 are arranged in sequence at the upper end of the installation chamber 101.

The heat insulation cotton 501 can improve the heat insulation effect of the sealing door 5, thereby improving the efficiency of the sintering furnace.

[0021] Working principle: During use, the sintering material is placed inside the holding crucible 8, above the zirconium beads 9. This allows the sintering material to move, preventing it from sticking to the holding crucible 8 during the pre-sintering process and affecting the sintering effect. Then, the positioning groove 804 at the lower end of the holding crucible 8 is aligned with the positioning block 802 at the upper end of another holding crucible 8, and the positioning block 802 is installed into the positioning groove 804. This facilitates the installation and placement of the holding crucible 8. The placed holding crucible 8 is then placed above the support base 4 inside the pre-sintering furnace 1. The silicon carbide heating rod 3 is controlled by the control panel 103 to heat the material. The silicon carbide heating rod 3 enables the heat inside the pre-sintering furnace 1 to reach the required temperature, thus enabling high-temperature sintering of the material.
