Technical Field
[0001] The utility model belongs to the technical field of furnace charging tooling, in particular to a furnace charging tooling for gypsum mold investment casting and roasting. Background Art
[0002] After drying and hardening, the gypsum investment molds need to be fired in a firing furnace to remove the wax pattern. Traditionally, the gypsum investment molds are stacked in a straddle-the-bone arrangement, with the number of layers decreasing from bottom to top. This limits the number of layers that can be loaded, resulting in high production costs. Furthermore, the gaps between the upper and lower layers are small, causing them to overlap and overlap, which can affect firing quality.
[0003] For this reason, a furnace loading tool for gypsum investment casting and firing is badly needed. Utility Model Content
[0004] In response to the above-mentioned defects in the prior art, the utility model provides a furnace loading tool for gypsum investment casting and roasting, comprising a frame and a plurality of support frames, the frame comprising a first upright pole group and a second upright pole group arranged opposite to each other on the left and right, the first upright pole group comprising two first upright poles arranged opposite to each other front and back, the second upright pole group comprising two second upright poles arranged opposite to each other front and back, a plurality of first support blocks and second support blocks of the same number are respectively arranged on opposite sides of the first upright pole and the second upright pole, the first support blocks on the two first upright poles correspond to the second support blocks on the two second upright poles front and back and left and right, that is, the first support blocks on the two first upright poles correspond to each other front and back, and the second support blocks on the two second upright poles also correspond to each other front and back, and at the same time, the first support block on the first upright pole corresponds to the second support block on the second upright pole left and right, and each support block is provided with a positioning block.
[0005] The support frame is set on the frame body, and the support frame includes two square tubes arranged in the front and back. A fixing rod is fixedly connected between the two square tubes. Positioning holes are set at the top of the left and right ends of the square tubes, and the positioning holes match the positioning blocks. Slots are opened at the bottom of the left and right ends of the square tubes for the support blocks to pass through.
[0006] Optionally, the area of the cross section of the inner cavity of the square tube is larger than the area of the cross section of the first support block.
[0007] Optionally, the distance between the two square tubes matches the distance between two first support blocks on the two first upright poles that are opposite to each other front and back.
[0008] Optionally, the length of the square tube is greater than the distance between the first support block and the second support block opposite to each other on the left and right, and is less than the distance between the first vertical pole and the second vertical pole opposite to each other on the left and right.
[0009] Specifically, the support frame can be placed between the left and right upright poles.
[0010] Optionally, the lower parts of the two first upright poles and the two second upright poles are fixedly connected together by a connecting rod.
[0011] In addition, the frame and support frame are made of high-temperature resistant stainless steel, which has the characteristics of firm support, high strength and high temperature resistance.
[0012] The present invention also includes other components that enable the normal use of a gypsum investment casting and baking furnace loading tool, which are conventional technical means in the field. In addition, the devices or components not limited in the present invention all adopt conventional technical means in the field.
[0013] The working principle of the present invention is to install the support frame on the frame body, and the specific steps are as follows: first, the left and right ends of the square tube are respectively placed on the support blocks of the corresponding first upright and second upright, and then the positioning blocks on the support blocks are inserted into the positioning holes at the ends of the square tube to position the support frame. The height of the positioning blocks is not greater than the depth of the positioning holes. In this way, after the positioning blocks are inserted into the positioning holes, their tops will not protrude from the top surfaces of the square tubes. Then, the remaining support frames are installed on the frame body layer by layer. After all the support frames are installed, the gypsum molds are placed on each support frame layer by layer. In this way, not only the number of furnaces loaded on each layer is consistent, but also the upper and lower layers are separated by support frames, and the gap is larger, which not only increases the number of furnaces loaded, but also ensures that the roasting quality meets the process requirements.
[0014] The beneficial effects of the present invention are that it has a simple structure and is easy to operate. The frame body and the corresponding number of support frames are placed according to the length of the roasting furnace and the number of gypsum molds that need to be roasted. It is flexible to use, and the gypsum molds are evenly placed on each layer of support frames. This not only ensures that the number of furnace loads on each layer is consistent, but also the upper and lower layers are separated by support frames with a larger gap, which not only increases the number of furnace loads, but also ensures that the roasting quality meets the process requirements, greatly improves production efficiency, and saves costs.

[0024] Example
[0025] like Figure 1-6 As shown, an embodiment of the present invention provides a furnace loading tool for gypsum investment casting and roasting, including a frame 1 and several support frames 2, the frame 1 includes a first upright pole group and a second upright pole group arranged opposite to each other on the left and right, the first upright pole group includes two first upright poles 3 arranged opposite to each other front and back, the second upright pole group includes two second upright poles 4 arranged opposite to each other front and back, and the same number of first support blocks 5 and second support blocks 6 are respectively arranged on opposite sides of the first upright pole 3 and the second upright pole 4, the first support blocks 5 on the two first upright poles 3 correspond to the second support blocks 6 on the two second upright poles 4 front and back, that is, the first support blocks 5 on the two first upright poles 3 correspond to each other front and back, and the second support blocks 6 on the two second upright poles 4 also correspond to each other front and back. At the same time, the first support blocks 5 on the first upright pole 3 correspond to the second support blocks 6 on the second upright pole 4 left and right, and each support block is provided with a positioning block 7, and the lower parts of the two first upright poles 3 and the two second upright poles 4 are fixedly connected together by a connecting rod 8.
[0026] The support frame 2 is set on the frame body 1, and the support frame 2 includes two square tubes 9 set in the front and back, and a fixing rod 10 is fixedly connected between the two square tubes 9. Positioning holes 11 are set at the top of the left and right ends of the square tube 9, and the positioning holes 11 match the positioning blocks 7. Slots 12 are opened at the bottom of the left and right ends of the square tube 9 for the support blocks to pass through.
[0027] The area of the inner cross section of the square tube 9 is larger than the area of the cross section of the first support block 5 .
[0028] The distance between the two square tubes 9 matches the distance between the two first support blocks 5 on the two first upright poles 3 that are opposite to each other.
[0029] The length of the square tube 9 is greater than the distance between the first support block 5 and the second support block 6 on the left and right sides, and less than the distance between the first vertical pole 3 and the second vertical pole 4 on the left and right sides, so that the support frame 2 can be placed between the left and right vertical poles.
[0030] In addition, the frame body 1 and the support frame 2 are both made of high-temperature resistant stainless steel, and have the characteristics of firm support, high strength and high temperature resistance.
[0031] The working principle of the present invention is to install the support frame 2 on the frame body 1.
