Description

Technical Field

[0001] This utility model belongs to the field of mold structure design technology, specifically relating to a mold for forming thermally conductive samples of unshaped refractory materials. Background Technology

[0002] Thermal conductivity is a physical property characterizing the thermal conductivity of refractory materials, and the commonly used measurement method is the water flow plate method. When measuring the thermal conductivity of shaped refractory products using the water flow plate method, they need to be made into circular samples with a diameter of (160-180) mm × (10-25) mm. Since unshaped refractory materials are in bulk and cannot be directly sampled, a mold is needed to shape the sample first. Existing sample preparation molds, due to their integral circular structure, are difficult to remove after sample preparation, and sometimes the sample is even damaged after removal, requiring re-sample preparation, which is time-consuming and labor-intensive. Utility Model Content

[0003] This invention provides a molding die for forming thermally conductive specimens of unshaped refractory materials, which solves the problems mentioned in the background art of existing specimen preparation molds, such as difficulty in removing the specimen, specimen damage, and time and labor costs after the specimen is made.

[0004] The technical solution adopted in this utility model is: a molding die for forming thermally conductive samples of unshaped refractory materials, comprising:

[0005] Base plate;

[0006] The mold sleeve has a semi-circular ring structure. There are two of them, which are symmetrically arranged on the surface of the base plate. The two mold sleeves are movably installed on the surface of the base plate. When the two mold sleeves are close to each other to the limit position, a cylindrical mold cavity is formed between the two mold sleeves. Each mold sleeve has an outwardly extending step at the end of its outer surface.

[0007] The limiting block has an overall U-shaped structure. When the two mold sleeves approach each other to their extreme positions, the limiting block can be fitted onto the stepped part of the two mold sleeves to prevent the two mold sleeves from separating.

[0008] The upper surface of the base plate has an upwardly protruding frustum, the diameter of which is the same as the inner diameter of the mold sleeve.

[0009] Side plates are installed on both sides of the upper surface of the base plate, and at least two parallel guide rods are installed between the two side plates. Guide holes are provided in the stepped part of the mold sleeve, and the guide rods slide with the guide holes.

[0010] The mold sleeve has a limiting groove on the side of the stepped portion and along the center line of the mold sleeve. The U-shaped inner wall of the limiting block has a limiting protrusion that matches the limiting groove. The cross-sectional shape of the limiting protrusion is consistent with the cross-sectional shape of the limiting groove. The limiting protrusion is slidably connected to the limiting groove.

[0011] The cross-sectional shape of the limiting protrusion and the limiting groove is semi-circular, rectangular or trapezoidal.

[0012] The surface of the mold sleeve is provided with threaded holes.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model has a reasonable design structure, which can realize the rapid assembly of mold by using two movable mold sleeves. After the assembly is completed, the limiting block is used to prevent the mold sleeve from shifting. After the sample is made, the limiting block can be removed and the two mold sleeves can be moved to the sides to quickly achieve the demolding effect. It has the advantages of convenient mold assembly and disassembly, high sample yield, and saving time and effort. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] As shown in the figure, a molding die for forming thermally conductive samples of unshaped refractory materials includes:

[0028] Base plate 1, which can be fixedly placed on the molding equipment during the actual sample making process;

[0029] The mold sleeve 4 has a semi-circular ring structure. There are two of them, which are symmetrically arranged on the surface of the base plate 1. The two mold sleeves 4 are movably installed on the surface of the base plate 1. When the two mold sleeves 4 are close to each other to the limit position, a cylindrical mold cavity is formed between the two mold sleeves 4. The outer surface end of each mold sleeve 4 has an outwardly extending step portion 401. By using two semi-circular ring mold sleeves 4 to replace the traditional single cylindrical sleeve structure, demolding can be quickly achieved after subsequent molding, thus improving work efficiency.

[0030] The limiting block 5 has an overall U-shaped structure. When the two mold sleeves 4 approach each other to the extreme position, the limiting block 5 can be fitted onto the step portion 401 of the two mold sleeves 4 to prevent the two mold sleeves 4 from separating.

[0031] The upper surface of the base plate 1 has an upwardly protruding frustum 101. The diameter of the frustum 101 is the same as the inner diameter of the mold sleeve 4. The frustum 101 is mainly used to limit the movement of the mold sleeve 4. When the two mold sleeves 4 come into contact with the frustum 101, the mold sleeves 4 can no longer move towards each other, which has a quick positioning function. At the same time, during the equipment debugging stage, the frustum 101 can be used to align the center of the hammer head of the forming equipment, which can also play a positioning role, thereby improving the sample forming accuracy.

[0032] Side plates 2 are installed on both sides of the upper surface of the base plate 1. At least two parallel guide rods 3 are installed between the two side plates 2. A guide hole 403 is provided in the step portion 401 of the mold sleeve 4. The guide rod 3 slides with the guide hole 403. This arrangement is mainly to ensure that the mold sleeve 4 has only the freedom of left and right movement in the horizontal direction. It is also to avoid damage to the sample due to the mold sleeve 4 flipping or other reasons during the demolding process after sample molding, so as to improve the qualification rate of sample molding.

[0033] The mold sleeve 4 has a limiting groove 402 on the side of the stepped portion 401 along the center line of the mold sleeve 4. The U-shaped inner wall of the limiting block 5 has a limiting protrusion 501 that matches the limiting groove 402. The cross-sectional shape of the limiting protrusion 501 is consistent with the cross-sectional shape of the limiting groove 402. The limiting protrusion 501 is slidably connected to the limiting groove 402. When using the limiting block 5, the two mold sleeves 4 need to be in contact. In this way, the limiting block 5 can be fitted onto the stepped portion 401 to prevent the two mold sleeves 4 from separating. Since the fitting method is adopted, the disassembly and assembly are more convenient, which helps to improve work efficiency.

[0034] Specifically, the cross-sectional shape of the limiting protrusion 501 and the limiting groove 402 is semi-circular, rectangular or trapezoidal. In this example, the cross-sectional shape of the two is semi-circular. Other shapes can also be used, which are not limited here.

[0035] The surface of the mold sleeve 4 is provided with a threaded hole 404. The purpose of providing the threaded hole 404 is to install a screw in the threaded hole 404 after the sample is formed, so as to move the two mold sleeves 4 to both sides.

[0036] In use, this mold for forming thermally conductive samples of unshaped refractory materials involves fixing the base plate 1 on the worktable of a forming equipment, such as a brick-making machine. The center line of the frustum 101 is aligned with the center line of the adjustable hammer above the equipment. The two mold sleeves 4 are then moved towards each other until they contact each other, and the limiting blocks 5 lock the two mold sleeves 4 in place. Unshaped refractory material can then be introduced between the two mold sleeves 4, and the hammer is used to press the refractory material, thus forming the sample. After the sample is formed, the two limiting blocks 5 are removed from the mold sleeves 4. A screw is installed at the threaded hole 404 above the mold sleeves 4, and the two mold sleeves 4 are pushed outwards to achieve demolding, completing the sample preparation process.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
