Description

Technical Field

[0001] This utility model relates to the field of refractory brick processing technology, and in particular to a hard alloy mold for irregularly shaped bricks. Background Technology

[0002] Carbide steel possesses extremely high wear resistance and can be reused after grinding. With a Rockwell hardness exceeding 70, it is suitable for mass production of large quantities of products. In actual production, over 200,000 pieces of pulp binder are produced using carbide steel. Ordinary steel molds, on the other hand, have a Rockwell hardness of only around 60, and the usable depth is only 0.1mm to 1.0mm, gradually degrading and not reusable, resulting in a lifespan of only about 600 molds. Using carbide steel molds significantly reduces production costs and increases efficiency. However, due to its high hardness, carbide steel cannot be machined and can only be ground using a surface grinder. Molds made from this steel are only suitable for producing standard bricks and cannot meet the needs of... Figure 1 To meet the production needs of irregularly shaped bricks, this utility model proposes a cemented carbide mold for irregularly shaped bricks. Utility Model Content

[0006] Preferably, the lower plate includes a plate-shaped portion and a block-shaped portion located at the bottom end of the plate-shaped portion, and the projection of the block-shaped portion on the horizontal plane is located within the projection area of ​​the plate-shaped portion on the horizontal plane.

[0007] Preferably, the notch extends downward and forms a sunken step on the block-shaped portion, the bottom end of the fixing plate is fixed on the step, and the upper end face of the fixing plate is provided with a second fixing hole.

[0008] Preferably, the upper end face of the fixing plate is provided with a guide slope on the side close to the frame.

[0009] Preferably, the thickness of the cemented carbide steel plate and the lower plate is at least 50 mm.

[0010] The beneficial effects of this utility model are: the fixing plate can accurately form the missing part of the irregular brick, ensuring the accuracy and regularity of the size of the missing part of the irregular brick, and meeting the special shape requirements of the irregular brick. The fixing plate and the lower plate are two independent plates, both of which can be processed by planar grinding. After processing, they are fixed together, thereby avoiding complex shapes and non-planar structures, so that the production needs of irregular bricks can also be met by hard alloy steel molds.

[0016] The present invention will be further described in detail below with reference to specific embodiments.

[0017] Example: This utility model discloses a cemented carbide mold for forming irregularly shaped bricks, used for molding such as... Figure 1 The irregularly shaped brick shown in the top view has a missing part at one corner. The structure of the cemented carbide mold is as follows. Figure 2-4As shown, the device includes a frame 2 enclosed by four hard alloy steel plates 1. A lower plate 3 is movably disposed within the frame 2. A lifting machine is connected to the lower end of the lower plate 3. A pressure plate is connected to the top of the frame 2 via a press. A fixing plate 4 is vertically fixed at one corner of the lower plate 3. Bricks are added into the frame 2. The fixing plate 4 is used to fill in missing parts of irregularly shaped bricks. The press drives the pressure plate to press down, pressing the irregularly shaped bricks into shape. Two adjacent sides of the fixing plate 4 and two adjacent sides of the lower plate 3 are located in the same vertical plane, which can accurately form the missing parts of the irregularly shaped bricks, ensuring the accuracy and regularity of the dimensions of the missing parts of the irregularly shaped bricks and meeting the special shape requirements of the irregularly shaped bricks. The fixing plate 4 and the lower plate 3 are two independent plates, both of which can be processed by planar grinding. After processing, they are fixed together, thereby avoiding complex shapes and non-planar structures, so that the production needs of irregularly shaped bricks can also be met by hard alloy steel molds.

[0018] The lower plate 3 has a notch 5 at its corner. The bottom end of the fixing plate 4 is fixed in the notch 5. The fixing plate 4 has two first fixing holes 6 on one side parallel to the length direction of the lower plate 3. The fixing plate is fixed to the side of the lower plate by bolts.

[0019] The lower plate 3 includes a plate-shaped portion 8 and a block-shaped portion 7 located at the bottom end of the plate-shaped portion 8. The projection of the block-shaped portion 7 on the horizontal plane is located within the projection area of ​​the plate-shaped portion 8 on the horizontal plane, which reduces the contact area between the lower plate and the inner wall of the frame, thereby reducing the friction between the lower plate and the frame and extending the service life of the mold.

[0020] The notch 5 extends downward and forms a sunken step 9 on the block-shaped part 7. The bottom end of the fixing plate 4 is fixed on the step 9, so that the fixing plate 4 has two support surfaces, the side and the bottom. The upper end surface of the fixing plate 4 is provided with a second fixing hole 10. The fixing plate 4 is fixed on the step surface of the step 9 by longitudinal bolts, so that the connection structure between the fixing plate 4 and the lower plate 3 is more stable.

[0021] The upper end face of the fixing plate 4 is provided with a guide slope 11 on the side close to the inside of the frame 2, which plays a guiding role when the pressure plate is pressed down, thus improving the ease of operation.

[0022] The thickness of the hard alloy steel plate 1 and the lower plate 3 is 50mm, which greatly improves the overall strength and wear resistance of the mold, extends the service life of the mold, and can adapt to long-term high-intensity and large-volume pressing work.

[0023] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
