Description

Technical Field

[0001] This utility model belongs to the field of molding die technology, specifically relating to a molding die for silicon carbide ceramic parts. Background Technology

[0002] A molding die, also known as a mold, is a mold made to scale according to the shape and structure of a real object. It is a tool used to shape material into a specific form by pressing or casting. Molding dies are commonly used in the production of silicon carbide ceramic parts. Plastic raw materials are added to a preheated feeding chamber, and then pressure is applied to the pressure column. The silicon carbide ceramic raw material melts under high temperature and pressure and enters the mold cavity through the gating system.

[0003] It gradually hardens and takes shape, thus allowing it to be die-cast.

[0004] When die-casting silicon carbide ceramic parts, water needs to be sprayed into the mold first to facilitate demolding. Currently, most of these processes are done manually by spraying or applying water, which is time-consuming and labor-intensive. In addition, when silicon carbide ceramic raw materials enter the mold cavity, uneven injection during the die-casting process may result in a grainy texture on the surface, affecting the quality of the ceramic parts. Utility Model Content

[0005] The purpose of this invention is to provide a silicon carbide ceramic component molding die to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a silicon carbide ceramic component molding die, comprising an upper mold base and a lower mold base with an internal mounting cavity, wherein a concave mold is provided on the lower mold base, and a water injection component for spraying water into the concave mold is provided inside the lower mold base, the water injection component comprising a water storage cavity formed in the concave mold, a flow pump, and an outlet pipe and an inlet pipe connected to the outlet and inlet of the flow pump, wherein the outlet pipe is connected to the water storage cavity;

[0007] A vibration assembly is installed inside the mounting cavity. The vibration assembly includes a vibration motor and springs disposed on both sides of the vibration motor.

[0008] Preferably, a punch corresponding to the die is mounted on the upper die holder.

[0009] Preferably, a positioning element and a guide element are provided between the upper mold base and the lower mold base.

[0010] Preferably, the positioning component includes a positioning rod and a positioning post installed at the bottom of the upper mold base, the positioning post being installed at the top of the lower mold base, and the positioning post having a positioning hole that matches the positioning rod.

[0011] Preferably, the guide includes at least four guide posts and guide holes that match the at least four guide posts. The at least four guide posts are symmetrically installed on the bottom of the upper mold base, and the guide holes are opened on the lower mold base.

[0012] Preferably, a water outlet groove is provided at the inner edge of the concave mold, and the water outlet groove is connected to the water storage cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) By setting up a water injection component, the water inlet pipe is connected to an external water source, and the flow pump pumps the flow into the water outlet pipe and into the water storage chamber. When the water level reaches the water outlet tank, it can be discharged from the water outlet tank and enter the concave mold. It flows down from the top of the concave mold to wet the concave mold, so that the ceramic parts can be demolded. Moreover, there is no need to manually spray clean water, making it more time-saving and labor-saving.

[0015] (2) By setting up a vibration component, the upper mold base is provided with an installation cavity. The vibration motor base or flange transmits longitudinal and transverse vibrations to the upper mold base and the punch, thereby driving the lower mold base and the die to vibrate. This makes the carbonized ceramic material in the die compacted evenly, ensuring that the surface of the ceramic parts after die casting is smooth and improving the production quality.

[0023] A vibration assembly is installed inside the mounting cavity. The vibration assembly includes a vibration motor 12 and springs 13 disposed on both sides of the vibration motor 12.

[0024] In response to the above, when using this silicon carbide ceramic component molding mold, before closing the mold, connect the water inlet pipe 8 to an external water source or water tank, start the flow pump 6 through the external control device, and the flow pump 6 pumps the water in the water inlet pipe 8 into the water outlet pipe 7 and into the water storage chamber 14. When the water level reaches the water outlet of the concave mold 9, it flows out from the water outlet into the concave mold 9, wetting the concave mold 9, so that the ceramic component can be demolded, and there is no need to manually spray clean water.

[0025] After the upper mold base 1 and the lower mold base 5 are closed, ceramic material is injected into the cavity mold 9 through the injection mechanism box. After injection, the vibration motor 12 is started through the external control device. The vibration motor 12 drives the lower mold base 5 and the cavity mold 9 to vibrate, so that the silicon carbide ceramic material in the cavity mold 9 is vibrated evenly, ensuring that the surface of the produced silicon carbide ceramic parts is smooth.

[0026] Specifically, in Figure 1 and Figure 2 As shown, in this utility model, a punch 2 corresponding to the concave mold 9 is installed on the upper mold base 1, which facilitates the die casting of ceramic parts.

[0029] The positioning components include a positioning rod 11 installed at the bottom of the upper mold base 1 and a positioning post 10. The positioning post 10 is installed at the top of the lower mold base 5, and a positioning hole matching the positioning rod 11 is opened in the positioning post 10.

[0030] The guide component includes at least four guide posts 3 and guide holes 4 that match the at least four guide posts 3. The at least four guide posts 3 are symmetrically installed on the bottom of the upper mold base 1, and the guide holes 4 are opened on the lower mold base 5.

[0031] In response to the above, when the upper mold base 1 and the lower mold base 5 are closed, the upper mold base 1 is connected to an external driving device, which drives the upper mold base 1 to move downward, so that the guide post 3 enters the guide hole 4 and the positioning rod 11 enters the positioning hole of the positioning post 10. The punch 2 and the die 9 will not be misaligned, thus ensuring the production quality of silicon carbide ceramic parts.

[0032] In addition, such as Figure 4 As shown, in this utility model, a water outlet groove 15 is provided at the inner edge of the concave mold 9. The water outlet groove 15 is located on the top of the concave mold 9 to facilitate the wetting of the concave mold 9 with clean water. Multiple water outlet holes can be provided on the water outlet groove 15 to facilitate the control of the water output. The water outlet groove 15 is connected to the water storage cavity 14.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
