Description

TECHNICAL FIELD

[0001] The utility model relates to ceramic product technical field especially relates to a ceramic faucet manufacturing mould. BACKGROUND

[0002] The ceramic faucet is widely used because of its smooth surface, corrosion resistance and other advantages, but its manufacturing process needs to realize the forming of complex internal flow channel through the slip casting forming mould. The traditional mould usually adopts the integral mould core structure, which leads to the difficulty in demoulding, the easy damage of the blank body and the low finished product rate. In addition, the existing mould has poor adaptability to the faucet structure with multiple branch flow channels, and the positioning accuracy of the mould core is insufficient, which affects the size consistency of the product. Therefore, a mould capable of realizing the rapid forming and convenient demoulding of complex ceramic faucet is urgently needed. SUMMARY

[0003] The utility model aims at providing a mould capable of realizing the rapid forming and convenient demoulding of complex ceramic faucet.

[0004] To achieve the above-mentioned purpose, the utility model adopts the technical scheme that:

[0005] A ceramic faucet manufacturing mould, comprising a mould main body composed of an upper mould and a lower mould, the upper mould and the lower mould being relatively buckled and arranged, characterized in that: a mould core assembly is further included, a mould cavity matched with the faucet is formed between the upper mould and the lower mould, the mould cavity comprises a horizontal section, a first vertical section and a second vertical section, the first vertical section and the second vertical section are arranged transversely and spaced apart, the horizontal section is connected between the upper ends of the first vertical section and the second vertical section, the mould main body is formed with a first inlet communicated with one end of the horizontal section, a second inlet communicated with the free end of the first vertical section and a third inlet communicated with the free end of the second vertical section, the mould core assembly comprises a first mould core, a second mould core and a third mould core, the first mould core is matched with the horizontal section and can be inserted into the horizontal section of the mould cavity from the first inlet, the second mould core is matched with the first vertical section and can be inserted into the first vertical section of the mould cavity from the second inlet, the third mould core is matched with the second vertical section and can be inserted into the second vertical section of the mould cavity from the third inlet, the second mould core and the third mould core inserted into the mould cavity can be respectively detached and inserted with the first mould core.

[0006] Through the adoption of the above technical scheme, the horizontal section of the mould cavity directly corresponds to the multiple channel flow channels inside the faucet with the two vertical sections, the problem that the traditional mould cannot form the complex internal cavity is solved, the second mould core, the third mould core and the first mould core can be sequentially extracted during demoulding, the ceramic blank body cracking caused by the structural interference of the traditional integral mould core is avoided, the three inlets correspond to each section of the mould cavity respectively, the slurry is filled from different directions during hot-pressing injection, the bubble residue is reduced, and the blank body density uniformity is improved.

[0007] The cross sections of the first mould core, the second mould core and the third mould core are all circular.

[0008] By adopting the above technical solution, the contact surface between the circular cross-section mold core and the mold cavity wall is uniform, and the slurry pressure distribution during injection is symmetrical, reducing the risk of local leakage caused by irregular cross-section shape.

[0009] The insertion end of the second mold core inserted into the second inlet has a first insertion groove adapted to the outer peripheral surface of the first mold core, and the insertion end of the third mold core inserted into the third inlet has a second insertion groove adapted to the outer peripheral surface of the first mold core.

[0010] By adopting the above technical solution, the insertion groove is tightly fitted to the outer peripheral surface of the first mold core, forming a mechanical interlocking structure to prevent the mold core from rotating or shifting laterally due to the impact of the slurry during the injection process, thus ensuring the consistency of the flow channel shape.

[0011] The second mold core and the third mold core are perpendicularly connected to the first mold core.

[0012] By adopting the above technical solution, the second and third mold cores are vertically connected to the first mold core, ensuring that the first vertical section and the second vertical section are precisely aligned with the horizontal section, thus avoiding flow channel deformation caused by misalignment.

[0013] The first mold core, the second mold core, and the third mold core all include a limiting part, which is circular and has a diameter greater than the diameters of the first inlet, the second inlet, and the third inlet.

[0014] By adopting the above technical solution, the limiting part forms a physical barrier to prevent the mold core from being pushed back out of the inlet by the high-pressure slurry during injection. When the limiting part abuts against the outer edge of the inlet, the insertion depth of the mold core is automatically fixed, avoiding the mold core being inserted too deeply or too shallowly due to human operation errors.

[0015] The first mold core, the second mold core, and the third mold core have the same diameter.

[0016] By adopting the above technical solution, mold cores of the same diameter can be seamlessly connected through standardized insertion slots, avoiding loosening of connections caused by dimensional deviations in multiple mold cores.

[0017] The length of the second mold core is 1.5-2.5 times that of the third mold core.

[0018] By adopting the above technical solution, when the longer second mold core is extracted first, the internal stress of the mold cavity can be released, and then the shorter third mold core can be extracted, reducing the risk of deformation of the blank caused by synchronous core extraction.
