Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure forming mold technology, specifically to a pressure forming mold for ceramic heating tubes. Background Technology
[0002] In the industrial production of ceramic heating elements, pressure forming molds are the core equipment that determines product quality and production efficiency. Traditional ceramic heating element pressure forming molds mostly adopt a metal mold assembly structure, achieving powder densification through unidirectional or bidirectional pressure. Gaps can easily form at the joint between the upper and lower mold bodies due to machining accuracy deviations or wear, causing powder to overflow during molding. This not only wastes raw materials but also requires frequent machine stops for mold cleaning, severely impacting production efficiency. Therefore, improvements to the forming molds are necessary.
[0003] In existing ceramic heating tube pressure forming processes, the material is typically extruded and die-cast using upper and lower pressure molds. However, during the actual die-casting process, insufficient lifting and anti-deviation capabilities of the upper and lower molds can lead to misalignment gaps during molding. For heating tube blanks with hollow cavities, the fit between the core and the mold cavity requires extremely high precision, resulting in serious defects that affect the quality of pressure forming. Furthermore, after molding, removing the formed material from the mold is inconvenient and requires manual removal, leading to high labor costs and poor mold removal efficiency. To address these issues, we propose a ceramic heating tube pressure forming mold. Utility Model Content

[0031] The beneficial effects of this solution are as follows: A U-shaped support frame 2 supports and supports the lifting hydraulic assembly 3. Operating the lifting hydraulic assembly 3 controls the lifting and lowering of the anti-deviation plate 4. Two limiting lifting blocks 5 slide and fit against the U-shaped support frame 2, providing limiting and anti-deviation positioning for both sides of the anti-deviation plate 4, resulting in excellent anti-deviation performance. The bottom mold 6 and top mold 7 achieve high precision after mold closing, with excellent anti-deviation performance. An opening lifting assembly 8 slides and fits against the inner bottom wall of the mold opening of the bottom mold 6. Operating the opening hydraulic cylinder 9 pushes the opening lifting assembly 8 upwards. After rising, the opening lifting assembly 8 pushes the formed heating element out of the mold, completing the removal operation. Automated mold removal is convenient, resulting in strong anti-deviation capability, high mold closing precision, high die-casting quality, convenient automatic removal, and easy operation, thus improving production efficiency.
[0032] Furthermore, both sides of the U-shaped support frame 2 are bolted with bolting seats 10, and the two bolting seats 10 are bolted to the top of the mold production table 1 on both sides respectively. The U-shaped support frame 2 is bolted to the top of the mold production table 1 by the bolting seats 10.
[0033] By setting bolt seats 10, which are bolted to both sides of the top of the mold production table 1, the U-shaped support frame 2 can be easily fixed to the top of the mold production table 1, making disassembly and fixing convenient.
[0034] Furthermore, the lifting hydraulic assembly 3 includes two sets of hydraulic cylinders, which are symmetrically installed on both sides of the top of the U-shaped support frame 2. The lifting anti-deviation plate 4 is located inside the U-shaped support frame 2, and the output end of the lifting hydraulic assembly 3 is fixedly installed on the top of the lifting anti-deviation plate 4.
[0035] By setting the lifting hydraulic component 3 to include two sets of hydraulic cylinders, the lifting hydraulic component 3 can remain stable during lifting and lowering, and is not easy to deviate or tilt. It can drive the lifting anti-deviation plate 4 to operate stably, making it convenient to use.
[0036] Furthermore, the U-shaped support frame 2 is provided with limiting posts 11 on both sides, and two limiting lifting blocks 5 are respectively sleeved and slid on the outside of the two limiting posts 11. The inner diameter of the limiting lifting blocks 5 matches and fits the frame of the U-shaped support frame 2 and the outside of the limiting posts 11.
[0037] By setting limit posts 11, limit lifting blocks 5 are respectively sleeved and slid on the outside of the two limit posts 11.
