Description

Technical Field

[0001] This utility model relates to the field of wax removal fixtures, specifically a 310S stainless steel wax removal sagger. Background Technology

[0002] Hot pressing is a common method of ceramic forming, especially for complex-shaped and thin-walled products. In hot pressing, paraffin wax is added as a forming binder. Before the product is fired at high temperature, the paraffin wax needs to be removed (dewaxing, wax removal, or degumming). The wax removal temperature is 1000℃±50℃.

[0003] Existing saggers are mainly made of porcelain clay. The ceramic product and adsorbent (alumina dewaxing powder) are mixed evenly, placed into the porcelain clay sagger, and then placed in a medium-temperature kiln for dewaxing according to a specific heating curve. However, the porcelain clay saggers will crack and break after a certain number of uses, forming solid waste, and have a short service life.

[0004] Meanwhile, due to the poor thermal conductivity of porcelain clay, products dewaxing using traditional saggers suffer from defects such as blistering, cracking, and wax runoff, resulting in a low product qualification rate. Furthermore, the dewaxing process is time-consuming and energy-intensive. Utility Model Content

[0005] The purpose of this invention is to provide a 310S stainless steel wax removal sagger to solve the problems of short service life and low wax removal efficiency of existing ceramic wax removal equipment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Example 1

[0034] like Figure 1 and Figure 2 As shown, the 310S stainless steel wax-removing sagger of this embodiment includes an inner cylinder 1 and an outer cylinder 2 with an open top. Both the inner cylinder 1 and outer cylinder 2 are circular. The inner cylinder 1 is used to hold the wax-removing product, and the outer cylinder 2 is located outside the inner cylinder 1. A receiving cavity is provided between the inner cylinder 1 and the outer cylinder 2. An inner through hole 11 is provided on the side wall of the inner cylinder 1, and an outer through hole 21 is provided on the side wall of the outer cylinder 2. The outer through hole 21 allows the receiving cavity to communicate with the outside, and the inner through hole 11 allows the receiving cavity to communicate with the inner cylinder. The inner cylinder 1 and outer cylinder 2 are made of 310S stainless steel. The receiving cavity includes a side receiving cavity 31, and a side high-temperature resistant adsorption layer 311 is provided inside the side receiving cavity 31.

[0035] In this embodiment, the outer cylinder 2 and the inner cylinder 1 are connected by welding. The inner cylinder 1 has an open structure at the top and bottom and shares a base plate with the outer cylinder 2.

[0036] Example 2

[0037] like Figure 3 and Figure 4 As shown, unlike Embodiment 1, the accommodating cavity includes a side accommodating cavity 31 and a bottom accommodating cavity 32. A bottom through hole 12 is provided at the bottom of the inner cylinder 1, allowing the bottom accommodating cavity 32 to communicate with the inner cylinder 1. A side high-temperature resistant adsorption layer 311 is provided inside the side accommodating cavity 31. A bottom high-temperature resistant adsorption layer 321 is provided inside the bottom accommodating cavity 32. In this embodiment, the inner cylinder 1 and the outer cylinder 2 are also fixedly connected, i.e., welded together at the top via connecting pieces.

[0038] Example 3

[0039] like Figure 5 and6 As shown, in this embodiment, the outer cylinder 2 is provided with an outer sliding member 22, and the inner cylinder 1 is provided with an inner sliding member 13. The inner sliding member 13 and the outer sliding member 22 are slidably engaged. The outer cylinder 2 is provided with an outer clamping notch 23. The inner cylinder 1 is provided with an inner clamping notch 14.

[0040] The inner cylinder 1 can be removed from the outer cylinder 2 by clamping the inner clamping notch 14 with clamping pliers. The separate inner and outer cylinder structure facilitates the installation of the side high-temperature resistant adsorption layer 311 and the bottom high-temperature resistant adsorption layer 321.

[0041] The bottom high-temperature resistant adsorption layer 321 is an alumina particle filler or an alumina cotton layer, and the side high-temperature resistant adsorption layer 311 is an alumina cotton layer; it can be replaced according to the different wax removal ceramic materials, such as zirconia particles, zirconia cotton layers, etc.

[0042] Taking Example 3 as an example, in use, the ceramic product to be dewaxed is placed in the inner cylinder 1, and filler is added to enclose the ceramic product. The filler is made of alumina particles. The side high-temperature resistant adsorption layer 311 and the bottom high-temperature resistant adsorption layer 321 inside the outer cylinder 2 are installed, and the inner cylinder 1 is placed inside the outer cylinder 2. Then, the whole unit is placed in the dewaxing kiln for dewaxing. As the temperature rises, the wax melts and moves. Some of the wax is absorbed by the side high-temperature resistant adsorption layer 311 and the bottom high-temperature resistant adsorption layer 321. As the temperature rises further, the wax is sintered and volatilized, completing the ceramic dewaxing. The outer cylinder 2 is clamped through the clamping notch using clamping pliers, and the inner cylinder 1 is removed from the outer cylinder 2. The dewaxed ceramic product is poured out, and new ceramic products can be put in for dewaxing. The side high-temperature resistant adsorption layer 311 can block the filler, preventing the filler from being discharged from the holes, and at the same time, it can make the heat distribution uniform. Due to its micropores, it facilitates the evaporation of wax.

[0043] The 310S stainless steel wax removal sagger in this embodiment solves the problems of short service life and low wax removal efficiency of existing ceramic wax removal equipment.

[0044] The above description is merely an embodiment of this utility model, and common knowledge regarding specific structures and characteristics is not described in detail here. It will be apparent to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this utility model.
