Description

Technical Field

[0001] The utility model relates to the field of refractory bricks, in particular to a refractory brick mould for batch molding. Background Art

[0002] Refractory bricks, also known as fire bricks, are a type of brick that is resistant to combustion and high temperatures, with a refractoriness of around 1700°C. They are usually made of refractory clay or other refractory raw materials such as refractory aggregates, and are formed and fired. The fired refractory bricks are light yellow or brown in color and are mainly used for building smelting furnaces. The current mainstream practice of refractory bricks is to first use molds to form them. The formed refractory bricks are sent to high-temperature furnaces for baking by transport carts. The number and quality of early mold forming are the top priority affecting the entire refractory brick production work. Refractory brick molds are divided into single-brick, double-brick and four-brick molds. Single-brick and double-brick are suitable for larger-sized special-shaped bricks. Four-brick molds are most frequently used and have the highest loss. When in use, clay is poured into the mold, and then it is formed by injection molding. The entire process from filling-injection-demolding takes about 2-3 minutes. However, for some demolding processes, the clay at the bottom of the mold is too much, the refractory brick demolding time is long, and the mold needs to be processed and filled again. The overall time can be extended to about 7-10 minutes, which greatly affects production efficiency. Utility Model Content

[0018] The following is combined with Figure 1-2 , the technical solution of the utility model is further explained:

[0019] like Figure 1 and Figure 2As shown, a refractory brick mold for batch molding includes a main embryo 1, in which a plurality of finished product cavities 2 are evenly opened, and a partition 5 for dividing the finished product cavity 2 into two independent injection cavities 4 is arranged in the finished product cavity 2. That is to say, a plurality of finished product cavities are evenly arranged along the axial direction of the main embryo, and the plurality of finished product cavities are separated by a solid embryo, and a partition is placed in each finished product cavity, and the finished product cavity is divided into two injection cavities of the same size by the partition. When the refractory brick is subsequently injection-molded, after the refractory clay is introduced into each injection cavity, a pressing plate is then used to cover the main embryo for overall pressing until the refractory clay is safely immersed in the injection cavity and flush with the top of the injection cavity, and the refractory brick injection molding is completed.

[0020] Furthermore, a vibrating member for exhausting the refractory brick forming process is provided in the partition 5. That is to say, a vibrating member can also be provided in the partition, and after pouring the refractory clay into the injection cavity, the vibrating member can be activated, and the air in the refractory clay can be exhausted by the high-frequency vibration of the vibrating member, which is helpful for the subsequent solid injection molding of the refractory clay; at the same time, when the refractory bricks are demolded in the subsequent molding, the vibrating member can also be activated, which is helpful for the refractory bricks to be separated from the inner wall of the injection cavity and demolded quickly.

[0021] In some embodiments, Figure 2 As shown, the vibrating member includes a vibrating column 6, which is arranged in the partition 5, and the vibrating column 6 has a built-in vibrating motor, and the vibrating motor is electrically connected to the external control switch through the built-in wire of the main embryo. In other words, a vibrating column is arranged in the partition, and a built-in vibrating motor is built in the vibrating column. By clicking the external control switch, the vibrating motor is powered on and started. The high-frequency vibration generated by the vibrating motor can promote the discharge of air inside the refractory clay, which is helpful for solid injection molding.

[0022] Furthermore, if Figure 1 As shown, metal gaskets for improving the wear resistance of the mold are arranged around the inner wall of the injection cavity 4. In other words, metal gaskets are arranged around the inner wall of the injection cavity, and the structural strength of the inner wall of the injection cavity can be improved by the metal gaskets, so as to avoid the problem that the inner wall of the injection cavity is damaged due to long-term injection of refractory bricks, which affects the molding quality of the refractory bricks.

[0023] In some embodiments, a heating sheet is disposed on the back of the metal gasket and located in the inner wall of the injection cavity, and the heating sheet is electrically connected to an external control switch through the internal wire of the main embryo. In other words, a heating sheet is disposed inside the main embryo on the back of the metal gasket, and the heating sheet is powered on and heated by clicking the external control switch to preliminarily heat and shape the refractory bricks after injection. At the same time, the vibration column can be used to prevent adhesion to the inner wall during subsequent demoulding, thereby achieving rapid demoulding.

[0024] Specifically, Figure 1As shown, the main embryo 1 is provided with a connecting cavity connected to each injection cavity at the bottom, and a removable support pad 3 is provided in the connecting cavity, and the support pad 3 and the injection cavity 4 integrally form an injection groove for making refractory bricks. That is to say, a connecting cavity is provided at the bottom of the main embryo, and the support pad is inserted into the connecting cavity, and the support pad and the injection cavity are used to shape the poured refractory clay. Finally, after the refractory brick is formed, the mold is turned over and the support pad is pulled out to prevent the bottom of the refractory brick from adhering to the support pad.

[0025] In some embodiments, Figure 1 As shown, the support pad 3 extends out of one end of the communicating cavity and an arc groove is provided at the bottom of the support pad 3 to facilitate pulling out the support pad. In other words, the arc groove is provided at one end of the support pad, which is convenient for workers to grasp the arc groove and quickly pull out the support pad.

[0026] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
