Description

Technical Field

[0001] This utility model relates to the field of ceramic sanitary ware, specifically to a master mold for manufacturing ceramic blanks. Background Technology

[0002] Existing ceramic products are typically produced through slip casting. The conventional production process involves first assembling a tray and a mold to form a complete molding cavity. Then, the prepared slurry is injected into the molding cavity of the mold, where it gradually solidifies to form a ceramic embryo. After the ceramic embryo is formed, the mold is opened and the ceramic embryo is removed.

[0003] During the grouting process described above, the mold absorbs moisture from the slurry, causing the mud particles to coagulate into a blank. The mold can be a plaster mold or a resin mold. However, the absorption of moisture by the mold leads to extreme dampness on its surface and inside. Such a damp mold must be dried before further use. To solve this problem, the applicant conceived of pre-creating air channels within the mold, using high-pressure gas to dry the entire mold and expel liquid from the air channels. The mold is made using a master mold, and the manufacturing process is as follows: the operator first arranges pipes in the molding cavity of the master mold according to pre-set requirements; then, resin or plaster is injected into the molding cavity, and after these materials solidify in the molding cavity, the mold is formed; subsequently, the mold is removed and all the arranged pipes are pulled out. After the pipes are removed, interconnected pores naturally form inside the mold, which serve as air channels.

[0004] However, when it is necessary to fix the tube to the curved surface of the mold cavity, especially during the injection of resin or plaster into the cavity, the impact force during material injection, coupled with the curvature of the surface, makes the tube, originally fixed in its position on the curved surface, prone to slippage or misalignment. This slippage and misalignment will cause the air channels inside the mold to fail to connect as designed, or air channels may not form at the corresponding positions on the curved surface within the mold, thus prolonging the drying time of the mold and reducing its efficiency. Utility Model Content

[0005] Based on this, and in response to the aforementioned technical problems, this utility model provides a master mold for manufacturing ceramic blank molds.

[0006] The objective of this utility model can be achieved through the following technical solutions: A master mold for manufacturing ceramic blanks includes a molding cavity, a first tube, and a second tube. Multiple first tubes are longitudinally spaced on the left and right sides of the molding cavity, and multiple second tubes are transversely spaced on the left and right sides of the molding cavity. The second tubes on the same side intersect with the first tubes. The outer ends of all tubes extend downward into the molding cavity. The master mold also includes multiple magnetic components for fixing each tube to the inner wall of the molding cavity. Each magnetic component includes a magnet pre-embedded in the master mold and corresponding to the distribution position of the tubes, and a support member attracted to the magnet and capable of fixing and supporting the tubes.

[0007] By employing the above technical solution, multiple magnetic components are set up. Utilizing the attraction between magnets embedded in the mold and the support components, the first tubes distributed on the left and right sides of the molding cavity, as well as the second tubes intersecting with the first tubes on the same side, can be individually fixed and stably supported. This prevents the tubes from slipping or becoming misaligned at the curved surfaces of the molding cavity due to the impact force during material injection and the influence of the arc structure. It ensures that the tubes remain in the correct positions according to preset requirements, allowing the internal air channels to be interconnected as designed after mold forming, and avoiding situations where there are no air channels at corresponding curved surfaces. Furthermore, traditional fixing methods, such as clips and bolt connections, often result in difficulties in separation during demolding and require additional disassembly. However, by using magnetic components for magnetic fixing, the magnets and support components naturally disconnect when the mold separates from the mold, eliminating the need for manual disassembly and making the process very convenient.

[0008] In a specific embodiment of this utility model: the support member consists of a strut and a nut threaded to the root of the strut, and the top of the strut has a U-shaped fixing head.

[0009] In a specific embodiment of this utility model: the support rod is a plastic part.

[0010] In a specific embodiment of this utility model: both the first tube and the second tube are flexible tubes. Attached Figure Description

Detailed Implementation

[0013] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1 and Figure 2 As shown, this utility model is a master mold for manufacturing ceramic blanks, including a molding cavity 10, first tubes 11, and second tubes 12. Multiple first tubes 11 are longitudinally spaced on the left and right sides of the molding cavity 10. Multiple second tubes 12 are transversely spaced on the left and right sides of the molding cavity 10. The second tubes 12 on the same side intersect with the first tubes 11. The outer ends of all tubes extend downwards into the molding cavity 10. Thus, the intersections of the first and second tubes on the same side can be temporarily secured with ropes. When the tubes are removed, interconnected pores will naturally form inside the mold, which can serve as air passages. Furthermore, the outer ends of all tubes extend into the molding cavity, facilitating the removal of the tubes from the molding mold.

[0015] A grouting hole 13 and a venting hole 14 are provided at the bottom of the molding cavity 10. The grouting hole 13 is used to inject plaster or resin material into the molding cavity 10, and the venting hole 14 is used to vent air during the pouring of material.

[0016] Combination Figure 3 As shown, this embodiment also includes multiple magnetic components 20 for fixing each tube to the inner wall of the molding cavity 10. Each magnetic component 20 includes a magnet 21 pre-embedded in the master mold and corresponding to the tube distribution position, and a support member 22 attracted to the magnet 21 and capable of fixing and supporting the tube. In this way, by utilizing the attraction between the magnet pre-embedded in the master mold and the support member, the first tube and the second tube distributed on the left and right sides of the molding cavity can be fixed and stably supported. This avoids the tube slipping or misalignment due to the impact force during material injection and the influence of the arc structure at the curved surface position of the molding cavity, ensuring that the tube can be kept in the correct position according to the preset requirements. In this way, the internal air channels of the mold can be interconnected as designed after molding, and the situation of no air channels at the curved surface position in the mold can also be avoided. In addition, traditional fixing methods, such as buckles and bolts, can cause difficulties in separating the connection during demolding and require additional disassembly. However, by using magnetic components for magnetic fixing, the magnet and the support will naturally break the magnetic connection when the mold and the mother mold are separated, eliminating the need for manual disassembly and making it very convenient.

[0017] In this embodiment, the support member 22 consists of a strut 23 and a nut 24 threaded to the root of the strut 23. The top of the strut 23 has a U-shaped fixing head 25. The strut 23 is a plastic part. Here, resin or plaster material is injected into the molding cavity, and these supports, together with the material, form the desired mold in the molding cavity.

[0018] In this embodiment, both the first tube 11 and the second tube 12 are flexible tubes.

[0019] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
